1182 ......'Twice Shy'

filler blocked back
<img src="<>/smile.gif" alt="smile" title="smile" height="15" width="15" />

When I first noticed the case lengths compared to the board widths I tried to fit the actual boards and ran smack into trouble.....
The boards wouldn't even start to go in to the case, the thickness of the board was way past the width of the case and now that I'd cut the boards length back and the packer fitted to the case it was time to find where the interference was coming from..... hope it's just a wayward dribble of resin or something simple...

I wasn't that lucky <img src="<>/mad.gif" alt="mad" title="mad" height="15" width="15" />

The cuts were first up and the bottom of the boards are now re-shaped ....... took me all of half an hour to get them into the desired shape.
Now the case slot, a visual inspection showed virtually no resin dribbles but I gave it a light sand regardless, which made no difference at all
<img src="<>/mad.gif" alt="mad" title="mad" height="15" width="15" />

My attention turned to the boards themselves, and it wasn't until I noticed some flaking varnish at the top that I realised what had been done to stop the fit......
A layer of varnish has been sprayed onto the boards and that layer was THICK..... ~1.5mm thick in some spots

I wasn't game to apply paint stripper incase the varnish had made it onto bare timber via a chip or cut, and I wasn't sure about the glassed surfaces reaction to the stripper either.
Next idea was to use the belt sander to rip it off, but I only had 80grit paper and I wasn't keen on the idea of cutting through the glass....

option c =

3 hours of hand sanding just to do 1 board <img src="<>/mad.gif" alt="mad" title="mad" height="15" width="15" /> <img src="<>/mad.gif" alt="mad" title="mad" height="15" width="15" /> <img src="<>/mad.gif" alt="mad" title="mad" height="15" width="15" />

The board on the right has been heavily sanded and yet the varnish is still visible as cloudy white spots on the trailing edge, these will get another sand to remove them entirely.
The up side is the finish on the sections I've done is brilliant, and the board slides sweet as into the case now....
1 down..... 1 to go
<img src="<>/tired.gif" alt="tired" title="tired" height="15" width="15" />
The 2nd board shouldn't be as bad, I'll start with the belt sander <img src="<>/wink.gif" alt="wink" title="wink" height="15" width="15" />

and while the sander was out......

I had a couple of 'sections' that were very orange peel in the finish and looked like a massive overspray mess, I was hesitant to go hard on them initially but after a few swipes with the hand block I figured I'd go a tad harder.

the white primer can easily be seen now I've given it a rub, this 'patch' extended back to the front beam (can still see a small patch where I started).... As I went I kept thinking I'd find an ugly repair under all this paint, its got to be here somewhere
<img src="<>/confused.gif" alt="confused" title="confused" height="15" width="15" />

and then a brain-storm said .... start up the front and have a light sand there, and that's when the

tree rings

of repaints appeared

green on green on white on green on white on original green
<img src="<>/crazy.gif" alt="crazy" title="crazy" height="15" width="15" />

and I kept going.....

and going.....

<img src="<>/smirk.gif" alt="smirk" title="smirk" height="15" width="15" />

until it was all gone <img src="<>/laugh.gif" alt="laugh" title="laugh" height="15" width="15" />

and no ugly repair under it all which has stumped me a bit as to why this was done in the first place, a color option that went wrong, was there a white blaze or something in there that was coated over....

what's really odd is this was only on the inner face of one hull, the other is clear of this paint mystery entirely.

yup definitely weird
<img src="<>/sick.gif" alt="sick" title="sick" height="15" width="15" />

remember that ugly repair I was looking for ?????

I found it ..... it's on the other hull
<img src="<>/grin.gif" alt="grin" title="grin" height="15" width="15" />

been a fairly serious impact here at some stage of her life

the other side of this repair is far smaller (about a 1/4) but similar in the style of repair, you can also see a small repair in the other hull right up at the front edge.

So why did I sand it all back ?????
I had a large area of bad orange peel paint, I have also sanded out the dark green stripes & original name which needed a light sand back from the 120grit I'd used.
I'm not running the block over the old girl like I am with karp, Twice Shy is just getting the orbital sander touch with a final swipe of 320grit, the finish will be smooth and blemish free and I'll have a better idea of what lies beneath it all and that's peace of mind as to what's under me <img src="<>/wink.gif" alt="wink" title="wink" height="15" width="15" />
and
its a major work time saver when I do the real teardown in the off season
<img src="<>/wink.gif" alt="wink" title="wink" height="15" width="15" />

today's tasks, 320 sand all the green, prime the repairs and sand back, flip it back over and get some trailer mods on the move
well that's the plan anyway
<img src="<>/wink.gif" alt="wink" title="wink" height="15" width="15" />

I saw the pics of Karp in the back ground, whats wrong with it? Why is it quicker to start from scratch on a unknown Mozzy then finish the boat you have been working on for months? Just curious, the season is slipping away...

Karp is the

good boat

, it has far superior equipment and the quality is 2nd to none, I want it to be right and that means time and $$$$ to finish it off to the level I'm after, sure I could rush it through, take a few shortcuts, but even so its still 2~3 months from hitting the water.
There are still a few headache's with Karp that need to be sorted, some of these are fiddly and require expertise I don't have so I'm relying on others and their 'free time' to assist with their services, as a result I have to

fit in

with them, others require time and money at the sail-makers, and I haven't even looked at the trailer or the replacement beams yet !!
<img src="<>/blush.gif" alt="blush" title="blush" height="15" width="15" />
Everything I've done with Karp so far has been calculated right out, even the weight of every thing I've added and taken out has been part of the process..... at the end of the day Karp is the pure race boat.

Twice Shy is much closer to making the water, sure I still have some ugliness to get past but its nothing in comparision to Karp's build, with Karp I've used fine hand tools for much of the process, Twice Shy has had a chainsaw thrown at it and it's likely to see it again !!!

If push came to shove I could probably be sailing Twice Shy within a week or two, it wouldn't look sexy n all that but it would be on the water.... Twice Shy is the hack, the one that's not seen a tape-measure of a set of scales and wont until I'm ready to rebuild it properly (once Karp is done most likely)

and

I need to be on the water, I need the practise and to get my head back in the game before I take on Karp and its abilities..... at the moment Karp is far better than I am and I need to get up to speed firstly.

Don't worry, there is still things happening with Karp, the new graffix were sorted recently and the way in which they'll appear on the boat is just about organised.....

<img src="<>/wink.gif" alt="wink" title="wink" height="15" width="15" />

Hows it coming? Ready for Sunday?
4 sleeps till race day.
Get it on the water!! lol worry about
Getting it right later.

Its close.......

I had a little opps with the rear deck on Sunday, gunna cost me a couple of nights to rectify it
<img src="<>/cry.gif" alt="cry" title="cry" height="15" width="15" />
w/end after Portland looks like launch day
<img src="<>/laugh.gif" alt="laugh" title="laugh" height="15" width="15" />

late Saturday arvo.....

<img src="<>/grin.gif" alt="grin" title="grin" height="15" width="15" />

had a spare hour so I had a little tinker..... <img src="<>/wink.gif" alt="wink" title="wink" height="15" width="15" />

don't know about this yet......

its certainly different ....... but then so is the rest of the boat

Sunday I decided to make some much needed repairs and changes to the trailer

cradle for the front beam was first off the drawing board

then came the rear beam's fold down cradle and mast support <img src="<>/smile.gif" alt="smile" title="smile" height="15" width="15" />

The rear carpeted 'loading pads' were also changed slightly.

Mostly finished now except for a coat of don't rust up on me just yet..
<img src="<>/wink.gif" alt="wink" title="wink" height="15" width="15" />

And it was about knock-off time when I was cleaning up from the days construction the poop did happen
<img src="<>/mad.gif" alt="mad" title="mad" height="15" width="15" />

I had a ~2metre length of the 40x40 tube I'd used left over and as I went to put it away I wasn't watching what I was doing I did the stupid thing
1 stabbed rear deck tearing out a great chunk of the ply instantly, as I jerked it away I plunged it into the other rear deck which split right down the guts.
<img src="<>/mad.gif" alt="mad" title="mad" height="15" width="15" /> <img src="<>/mad.gif" alt="mad" title="mad" height="15" width="15" /> <img src="<>/mad.gif" alt="mad" title="mad" height="15" width="15" /> <img src="<>/mad.gif" alt="mad" title="mad" height="15" width="15" />

after several minutes of expletives......

came several more minutes of colorfull mutterings

Tired / not focused / looking forward to the roast dinner I could smell all contributed but I have no-one to blame for this error except myself.

So with a full belly of yummy roasted beef I headed back to the shed to butts the damage, 10 mins later the rear decks were no more and I'd cut in some stringer slots in much the same manor I did Jurassic Karps rear decks

the 2 small stringers will give better support to the rear decks and offer the same to the inspection ports.
I've left ~3mm of clearance between the inspection port and the stringers, I had zero clearance on Jurassic Karp so lining up where the hole was to be cut had to be super accurate, didn't make that mistake again <img src="<>/wink.gif" alt="wink" title="wink" height="15" width="15" />

As of last night the stringers have been glassed in and sanded back ready for some new ply decking.

I wasn't going to touch any of the decks until the off season and at this stage that's still the plan.
The front and main's will get a quick coat of paint just to seal them up, with new rear decks I wont be painting these bits as I want to have the entire deck area in varnish, so for the short term I'll have colored fore and main decks and varnished rear decks....

on the plus side......
Atleast I wont have to replace the rears come winter

<img src="<>/smile.gif" alt="smile" title="smile" height="15" width="15" />

Slap it together and come racing!! Haha
Like you said its the hack job.
Not like the other three mozzis
Are works of art haha

yeah, but they FLOAT

yeah I know.... been a tad slack of late, family / work and car club have all interfered with the time availability, how dare they !!!

rear decks are done and ready for varnish.....

<img src="<>/smile.gif" alt="smile" title="smile" height="15" width="15" />

Stringer just visible inside the inspection port hole....

timber packer in the case slots has also been finished off, the decks are all sanded back and ready for a coat of white paint...

yep that's right, WHITE for the main and fore decks, They'll go in the off season and new decks will be varnished to match the rears
<img src="<>/smile.gif" alt="smile" title="smile" height="15" width="15" />

I also finished off some more of the trailer mods I'd started, hold-down bolts are now all machined up and installed .... 1 main one holds the front beam at the mast step and 2 hold the rear beam down.
The 2 rears have been machined so that they have a small locating pin and these line up with the spare holes in the rear track..... this holds the boat dead rigid.

front mount:

rear mount in fabrication:

**** welds
<img src="<>/wink.gif" alt="wink" title="wink" height="15" width="15" />

Further mods to the trailer will follow
<img src="<>/wink.gif" alt="wink" title="wink" height="15" width="15" />

The lights and numberplate will be fitted up later, and this was the easiest and quickest solution I could do....
As for legal.... meh <img src="<>/smirk.gif" alt="smirk" title="smirk" height="15" width="15" />

48/1353

One week to go, looking forward to seeing it
On the water! <img src="<>/smile.gif" alt="smile" title="smile" height="15" width="15" />
Al

With the car club stuff now out of the way until Febuary hopefully I wont loose another w/end....

oh yeah like that's going to happen <img src="<>/mad.gif" alt="mad" title="mad" height="15" width="15" />

first up I get the flu, so last Saturday and Sunday are gone as the couch and bed are as far as I can be bothered to move between

So Monday seems like a good day to take off work and recover from the nasty virus that's tried to kill me during the previous 2 days.....

Monday is paint day.... time to refresh the green, its a nice warm 30degrees, the heater is on aswell kicking the shed's temp up to just under the 40C. perfect for a glass finish....
<img src="<>/laugh.gif" alt="laugh" title="laugh" height="15" width="15" />

and glass we get ....

looking good.....
<img src="<>/cool.gif" alt="cool" title="cool" height="15" width="15" />

Or so I thought .......

Tuesday morning pics... <img src="<>/cry.gif" alt="cry" title="cry" height="15" width="15" />

overnight the paint has reacted severly to something, patches like these are intermittently spread over each hull, some smaller than a thumb-nail while others are quite large.
Totally random as to the placement of each patch..

only one thing to do......

<img src="<>/mad.gif" alt="mad" title="mad" height="15" width="15" />

Wednesday night.....
Thursday night.....
Friday night..... are spent stripping off ALL the primer and top-coats

Saturday morning is spent sanding

Saturday arvo and the primer is applied

This morning saw the primer sanded back and this afternoon saw the new coat of green applied.
Busy w/end <img src="<>/tired.gif" alt="tired" title="tired" height="15" width="15" />

Pic's when I know its all good.

The culprit at this stage appears to be a contaminated cloth that I used to wipe down the hulls prior to the original green being applied.
I wont know for sure until tomorrow, I used new cloths from an un-opened packet this time and I did a test with a cloth from the pack I think is contaminated, hopefully the old car door will be as wrinkled as nanna and the boat will be smooth as silk....
waiting waiting waiting

and inbetween all of that, I managed to make more alterations to the trailer and its now also ready for a fresh coat of paint.
Mods included shifting the mudguards so that they sat parralle to the chassis instead of the 2" angle they sat at.
Several lugs and other old welds cut off and cleaned up flush.
The main supports from the main chassis to the carpeted supports were shifted further inboard to assist the new beam supports.

all up its looking much more like a trailer should and is far more user friendly.......

Trailer color..... green or white ?????
<img src="<>/confused.gif" alt="confused" title="confused" height="15" width="15" />

decision made...... found some white I didn't know I had so figured I'd use it up and save the green for another job....

trailer mods all done, sanded back and sprayed.... lights fitted so now its ready to go <img src="<>/grin.gif" alt="grin" title="grin" height="15" width="15" />

sail-box is on the drawing board.... being in the steel fabrication industry I think I'll do a nice color-bond job
<img src="<>/wink.gif" alt="wink" title="wink" height="15" width="15" />

meanwhile........

Twice Shy has been sitting on Jurassic Karp's trailer <img src="<>/smirk.gif" alt="smirk" title="smirk" height="15" width="15" />

I could get the boat onto the trailer by myself without any real dramas, problem became I couldn't turn it over without the soft paint being marked.......
So I took it to work and used the overhead crane to spin it over and then re-fit it to Jurassic's trailer...

Its now 6 days since the respray and today is the first day I've been happy enough to put it outside for the day.
We live in a forest so the bird life is heavy .... as is the poop they splatter everywhere, soft curing paint and birdy poop is not a good combination so its stayed in the shed until now.

out sunning for the day, this was taken just on sunset

nice finish... <img src="<>/cool.gif" alt="cool" title="cool" height="15" width="15" />

and no contamination

Looking good!
I'd be interested to know if you nailed the reason for the orange peel in random places. A while back we had the same issue when painting an Opti for my son. It only puckered up in a few places and was quite random. We figured the only thing was that there was a 'softer' or damper section of paint. It was only on the interior, and relatively easily fixed. Hopefully you'll be able to get it wet soon!

No I haven't really nailed it down to a single thing.... possibly a combination of a few factors <img src="<>/confused.gif" alt="confused" title="confused" height="15" width="15" />

1/
First up were the cloth wipes I use to clean off the dust etc when I prep-wash the primer. Prep-wash is used as a cleaner and removes any gums/glues/silicates etc that can contaminate paint, the cloth pack was left out of its cupboard for a few days so contamination may have occurred there.

2/
Heat may also of had an effect, after reading the directions I found it wasn't best to use in hot temps, specifically above 30dergee, it was 29 on the day and I did have the heater on as well so at a guess it would have been nearing 40degrees in the shed.
Also with this, I did shut down the heater in the cool of the evening, it was around 20degrees outside so perhaps the rapid temp drop had an effect....

3/
off chance this one but..... maybe I'd laid down the 2nd coat a tad heavy ??????
Usually I'll hang a light coat first and allow it time to tack off, just dry enough to touch really gently but not completely dry, pending on the day that tack off can be 15mins through to 2~3hours.
The 2nd coat I applied was hanging on well so I slowed the gun down a tad and laid it on a bit thicker.....

<img src="<>/confused.gif" alt="confused" title="confused" height="15" width="15" />

Before I resprayed the boat I did a test on an old car door I have here as a test bench, half was wiped down with the cloths and the other half done with new cloths, I also cooked it at 40degrees and laid down the same style of coats......
I still got the peel effect, mostly on the bad cloth side but had some on the good cloth side as well..... <img src="<>/shocked.gif" alt="shocked" title="shocked" height="15" width="15" />

So.....

combination I guess, contaminated cleaning cloths, way too hot for the paint.

I've eliminated the spray style as I used the same style on the respray that's come out perfectly on the boat.

The respray was also done on a much cooler day ~20degrees and without the heater being used at all.

On another note:
we had some steel work do the exact same thing, strangely enough it was sprayed by a co-worker on the same Monday I did the boat. The 310-UB beams had very similar patches of peel effect and again only in some areas, the boss put it down to the heat of the day and an extra thick coat of industrial paint & ...... someone that doesn't normally paint doing the job.
<img src="<>/grin.gif" alt="grin" title="grin" height="15" width="15" />
So I wont rule out Monday as one of the possible causes either

<img src="<>/laugh.gif" alt="laugh" title="laugh" height="15" width="15" />

Today I decided I didn't like the white decks, just wasn't going to work with the final

look

I'm after....
I have already fitted new rear decks so I wanted to paint them in the style I want as a finished product when all the decks are replaced .....

so.....

The green decks are now finished
<img src="<>/grin.gif" alt="grin" title="grin" height="15" width="15" />

the rear deck...... just needs a coat of clear now and its done

I'll follow the same style on the main and forward decks when they are replaced......
<img src="<>/smile.gif" alt="smile" title="smile" height="15" width="15" />

The orange peel affect, is caused by applying too thick off the gun, to get auto finish thinner coats and more of it, what I saw in the pics is called fish eyed, means contamination on the cloths or on the work, usally siliconis the main cause and oil. other reasons undercoat not cured properly. Orange peel affect is on almost everything that is industral, as its a good strong coat and will last for years, auto finish is good bht need to be upkept
