Just a post of some roughed in clay work. Slow going, but all part of the plan I'm afraid.

Ongoing clay work...here you can see that there are still a lot of little cracks and crevices to fill - one day at a time - this stuff is worth the extra effort later on

Somewhere to Pry

I will leave the clay in these pry locations when I flip it over and mould the upper flanges. This will give a nice spot to get the crows foot into when separating the finished upper and lower mould sections. I've tried to target potential problem areas while placing them around the periphery.

1/4"-20 Flange Bolt Thread Inserts

Be careful not to over tighten the screws. Just pull them down flush.

Every time I go to use this mould and I don't have tighten a hundred nuts and washers onto all those bolts, I'm gonna grin from ear to friggin' ear! Just set the clutch nice and loose on the driver and give those 1/4" bolts hell. These thread inserts are going to save so much time it's not even funny.

So it looks like you are setting this up to be a three piece wing mold. Is that the reason for the wall you are building behind the leading edge there?

You're on the right track Hutch, but I'll also be doing separate sections for the tips on the upper side. This will allow for some processing options down the road. If I need additional access when installing the leading edge and spar, I can leave the upper tip sections off, and get inside there. A strong joint along the spar is more critical than the tip seam which is more of a cosmetic issue and is easily serviced by a straight forward, non-joggled butt seam.

So it will actually be 5 pieces. I hope that made some sense for you.

These are garage door hinges. I had them laying around from a past project and won't be needing them. I thought this might be a good opportunity to try something new and hinge the two main sections of my wing mould. If it doesn't work out, I will simply remove the hinge pins. I will align their axes with the laser level to give it the best shot at working since they can't simply be mounted flat against the angled back wall.

It's the classic risk vs reward. The question is - are yours big enough to get an angle grinder that close to 3 years work?

I'm not finished cleaning up yet but I needed a break, so here's some pics for today.

These hardwood blocks were $0.50 ea at the woodshop supply store.

Here's their website. They have lightweight ply too...

www.workshopsupply.com

Notice that I've set the hinge pins to level when the blocks are placed on the mould face where they will become part of the finished mould base.
