A smaller "Mill" file should cut those cornerss and edges. Just go slow, light pressure. Hard to put the metal back on.

NO, don’t bother. Your sail is NEVER going to touch the track at the mast base.
Go back & read the legacy assembly manual you have.
Look at Item #51
The sail does not, (and cannot) be fed in from the base of the mast. Look at your mast, about 18” up from the base. The sail inserts there, then once raised, the “sweeper” gets fed into that slot & pulled down.
Everything you need is in that little document.
The only thing you should think about is sealing that base & all rivets so the mast won’t fill with water when you flip it.

thanks again Ed that works perfectly.
However, instruction 52 says to make sure halyard is inside the slot in the mast.
Unfortunately I cannot see because the copy of the pictures are so shitty.
I think there referring to another type of mast

The wire lock system, which I have, says to hook the ball in the halyard lock. It then says to hook halyard to halyard snap in the front of the mast to keep halyard from flying loose.
It then says it is not intended to hold up the mainsail.
What is intended to hold up the mainsail?

Once again thank you Ed
I raised the sail the this way and it works very smoothly.
The mast appears to be sealed well.

This is a 5.7 mast top. Very simple design and the ball and hook is for holding the sail up, not the halyard below the hook! A 5.8 mast has a much more advanced design with hook and ring.

Thanks that is what I have. I just read the manual
which states 52 .wire lock system "hook the halyard on the halyard snap provided at front of mast"

Anyone know what the halyard snap is?

The small ball that is swaged onto the wire halyard...it hooks under the SS fork that is on the front of the mast, about 18” down from the masthead.
Pull til the ball is just below that fork. Keeping halyard centered on mast, bring it right into the mast, you should be able to see the wire position itself in the small fork near the masthead. Release halyard, the ball will catch on the fork.
To drop the sail, simply pull halyard down a bit to get ball out of the fork, then move the halyard outwards.
Halyard snap- there should be an “eye” riveted to the front of the mast, about 3’ up from the mast base. It’s the same type of “eye” you were thinking of shackling the forestay to. Get a shirt piece of bungee,tie a stopper knot in one end. Feed bungee through this eye, then attach a shock cord snap to the other end.
Once you raise the sail, you attach this snap to the small ring, (where the wire & rope halyard meet). Make the bungee a length that will provide some tension on the wire portion of the halyard once connected. This keeps it from flopping around. Cool the line portion & stuff in the tramp pocket.

Be aware that whatever is swaged on your halyard has a limited lifespan. If you see little wires starting to pop out from around the swage, time to replace. Sometimes it can slip when under load, the downhaul puts a lot of pressure on it, time to replace. Find a rigger that has the equipment to create the enormous pressure needed to use an aircraft fastener (ball) rather than a copper swage and it will never slip and last much longer.

Yes, I do t think a copper swage would hold up very long, it’s just too soft.
Both mine are a small ball, & have lasted decades.
