Fuselage February 2005 Updates February 21, 2005 Construction of Firewall Saturday morning got started on drilling out all the holes in the stainless firewall. There are 2 sizes of holes. #30 around the edges and #40 in some of the cross members. I used lots of biolube on the bits. Next was lots of counter sinking all the aluminum angles to mate up with the dimples in the firewall. I mounted the countersink tool in the drill press. Setup the proper depth and away we go. This took allot longer than I thought it would. Next I setup the DRDT-2. I cannot emphasize enough how cool this tool is. Even with the stainless firewall this thing just cranks out perfect dimples and nice and quite. The only problem is I could not dimple around the edges of the firewall without a longeron yoke. I called Phil B. and he said I could borrow his to finish up. I will get that tomorrow. Looking at the dimples of the #30 holes in the firewall I rechecked the countersunk holes. I found I had to redo most of the #30 holes to get the dimples to seat properly. Last I buffed all the stiffeners and gussets with a scothbrite pad and preped them for priming. Monday is a holiday and the weather cleared up so I was able to get the priming done. Then Harley Dave called and asked me to go take his boat out for a test ride. We met Rob from Custom Kolors at the lake for the test ride. I talked with Rob about doing the paint on the plane when completed. I think he would do an awesome job.
