This is the current thinking / possible option for the baffle penetrations - gang up multiple plates together and make a bigger hole in the middle. A quick bit of CAD work.
And some scrap AL sheet. Seems to work OK, although I need to modify my drawings slightly.
This is the other side - I should be able to get the 1" connectors thought the gap ;-)
Then onto the oil door - more drawings, this time for the hartwell latches.
Drill, sabre-saw and files.
After cleco'ing the hartwell latches on, it is obvious the 1/32" step for the catch isn't going to be enough. I marked the inside of the cowl and decided to just remove the material and build up as needed.
I tried to just cut back the 'latch' areas, but in the end took out a larger area and added some .020" AL stricker plates.
Masked up / protected the cowl and latches for glassing - a double layer of electrical tape seems to work really well, one cured - sand back to the first layer is removed, then peal bak the second (lower) layer for a fine finish. A third layer of tape can be usd to remove excess resin if that is needed.
Dad glassed in the mini-half round previously made into the FAB - a little flox around the edges helped greatly in getting a smoothing contour - hopefully the whole of this will be outside the line of the K & R filter.
I rivetted the one half of the piano hinge to the oil door and topped with a small piece of 2oz cloth and peel ply.
Then the latch recesses - difficult to see in the photo, but a AL strike plate bedded on flox with a layer of 2oz over it. Then I just waxed the latches and cleco'd everything up. Tomorrow hopefully I'll be able to still open the door!
Dad also spent a few hours working on some gear stands that can be jacked up - more photos once complete.
The second part of the ACS order got delivered - a 'huge' box, with lots of worms and box in it, which contained lots of foam and a REALLY small vertical card compass. It cost US$70 to ship this large box (3lbs weight) to me - rather frustrating to be spending money on shipping 'air'.
