Wing Mould Day One

In order to mould the leading edge without a seam line, I need to stand the plug on the trailing edge. Easier than it sounds...

Rule #1 of Modelling - Waste not; want not.

This is the section of my junkpile desk that I did not have room for in my kitchen. The top is steel and is complete with T-slots. Best of all it's free!

The T-slots will let me bolt on some fixturing that can be removed or adjusted as necessary. If you can't see it yet - stay tuned, this thread is about to come to life again.

PostScript - you know, I probably drove by a thousand junk piles without a second glance - but a steel top of the right length to fit my wing mould pulled my truck to the side of the road without a second thought - crazy how your subconscious is always watching....

I did some shopping this morning. I found a source for two interesting items only three doors down from my new apartment.

Half-round wooden knobs for registration between mould sections.
These were $0.22 each.

Coroplast Sheet - this is a very interesting material...
I will be using this material for parting planes. $1.39/sq/ft^2 is a little steep, but most of that charge was for the cutting service. It's just what they had ready to go; they thought they could custom cut me larger sections cheaper than what I picked up today. It has a nice smooth surface but there are undulations from the underlying internal structure. The ripple will provide some additional self-alignment in areas were a half-round registration key will not work.
The more interesting property of this material is it's strength to weight ratio in terms of longitudinal shear and compression. Will I be using longer lengths of this to cut ribs and a spar shear web from rather than ply and balsa? There's a very good chance.

Not to jump around too much, but I also found a heat source for my canopy mould. $10 on sale from $50 - wow I think this thing should work great. I read a few reviews and they were all outstanding. (sometimes I'm a little leary about this particular brand name...)

I thought about making up an elaborate heating station, but frankly, I don't think I could've done any better for the cost.

It's a fine line and I'm not sure which side this one comes down on....lol
At least I should be able to sit in my chair rather than standing bent over for hours while I make up this leading edge section.

(I never claimed to be a carpenter....)

...more to come, but I had a couple of minutes and these are necessary steps, so....

#1 - Ensure parting board is clean.
#2 - Wax on, wax off. 3X Carnauba paste (small, small circles)

Dime-in-clay corner fillets will form upper, outer radiused edge of mould face once all white board formers have been removed later.

The parting plane along the trailing edge of the flap bay has turned out quite well and has been carefully positioned to fall precisely at half thickness. This will give the best case scenario for trimming along the mould edges prior to joining.

This clay work isn't finished yet. Stay tuned, there's still plenty of work to do before we paint on that silicon carbide tooling coat.
