made a dimple die holder today. played with the drdt2 I made. Mucking about with the cleaveland tools dimple dies I got a great result...plenty of pressure...slight shadow more on one side so a little shimming to do. also not proper alclad just some rubbish 28 thou Ali I had laying around so ill wait till i get the right stuff before shimming it and get it perfect...nice flat dimples though and nicely formed on the back side.

These Bad boys waiting for work. A test of two different dimple die sets. 4 are done with CT dies and 4 are not. Care to guess which ones?

Default well box 1 of the empennage is here.

Box one arrive and no damage...cannot inventory as I am guess that is in the other box which was split up from this one somewhere. hopefully tomorrow. Also tomorrow another box from Vans with the practice kit and a few items...including clecos, scotch brite etc.

Also been working on getting my compressed air dry...done a small condensation type arrangement with stuff from home.

may help to condensate some moisture out and be able to drain it...I have the filter and a new desiccant water trap to fit. The desiccant will be just prior to the hose for the spray gun. I was going to rattle can it....but have now decided to make a booth...get better gear and do it with non toxic stewart systems ekopoxy. Maybe the next best thing to alodine and zinc chromate...at least i wont have that super nasty stuff around. The gun has a 1.6mm tip as stewarts recommend 1.4 to 1.8. I have a large three phase compressor so air is no issue.

Also cobbled together a rib straightener from bits I found at home....seems to work well on a scrap test rib I was given.

One question i have is the size of the holes....pre punch is number 42. my yard store dimple dies fit into those holes. my cleaveland ones do not...the cleaveland ones measure .094. why do we use a #40 making the hole .098 before dimpling?....#42 is .0935 and 3/32 is .0938 and 41 size is .096.
dimpling with the #40 yields a larger hole than anything else (.103)meaning the 3/32 rivets move about in them. dimpling after a #41 (both using the cleaveland dies) yields a .099 dimple hole...obviously lots of aircraft built like this without issue im just wondering why dimple dies are not closer to a finished rivet size?

Default Underway.

After setting up my machines and paint booth I got the practice flap done. Learnt a lot…got a bent trailing edge…rest of it seemed ok. Got to building the VS.

The paint booth still needs a door….I have some stick on zippers coming today. The booth is cobbled up out of stuff mostly from home. I’m surprised that the fan blows air through the booth and pressurises it well!….good air coming out the far filter. I’m using Stewart systems eko poxy.

I have a bandsaw, sander and I made the linisher. I geared it down turning the 3m wheels at 1600 rpm. One medium and one fine. Lots of working room around the wheels….the vacuum system helps a lot…

The VS appears to be coming out ok so far….I’ll see what happens when I get near it with the rivet gun. It’s match drilled ready for dimpling.

put a deposit on an IO-360 M1B with two P mags. **** price rises...wrong time for the engine but another 15% is huge. 13% 6 months ago....how long will they sit inhibited and still be ok? wont see it until next year...longer the better.

Had to also dep on the finishing kit although vans is not enforcing it currently due long lead times. still i did it to stave on any more price rises on that too.

I ordered the tail wings and fuse last june and since then its gone up by $4000 so glad i did that.

here is the vertical stab. happy with the way it came out. into the rudder and horizontal stab now.

Hey Glenn,
Looking good, you are really getting into it, the shop looks nicely set up so that will help.
When the engine arrives you can preserve it longer term by over-filling with motor oil so that everything inside is bathed in oil and no contact with air. Or, make a dehydrator that pumps through dried air. Prices are only going to go up further I expect!
Cheers,
Paul.

thanks Paul. I guess im reasonably well covered on the cost rise front. exchange rates still are a factor as they will come a calling for the balance at some stage next year. cannot ask for the motor past 31 dec 2022 however i dont see that as a problem because like vans lycoming are inundated with engine orders out their ears...i dont think ill have to pay till mid next year. The finishing kit ill use in its entirety except the spinner which I removed as I'm going to go fixed pitch Catto.

Not reinventing the wheel just be nice to have everything bolt up and fit. not interested in fancy exhausts or CSU's....just an efficient quick fit up. I have been down the road of putting every mod i could on my race car and all it did was create more problems, time spent and cost.

my formula is a bone stock rv7 with a nice bit of paint, a stock M1B with fixed pitch, G3X avionics package and the sliding canopy. only thing that is a want is a ballistic recovery chute....im not scared of the RV or flying...got 20000 hours in aeroplanes....just a personal want.
