The project continues. Fun when your saw kerf is as narrow as your scribe line. :wink:

I'm only making the metal bits for a friend who is the wood worker/pilot. I'm waiting engine choice for the mount but I think he mentioned Continental.

Interested in seeing more of the metal bit progress, tools etc.?

Sure! Love seeing what others can do to perfect their art. Students used to look at me like I was nuts when I'd tell them they were becoming artists, until they'd done complex fabbing and a lot of them told me 'you were right' It IS art.
(plus I don't have to cut my fingertips up!) :lol: :wink:

It has been a great time and once you find the connection, it doesn't make much difference how you apply it. From these Pietenpol bits, to armor I made for my kid, to the racing engines, it all works the same.

My grandfather told me when I was young, "Learn to work with your hands and you will always have work."

Bet the armor comes in handy @ the wedding buffet line. 360 or 410 motor?

That looks like a coping saw. You can't be cutting steel with a coping saw.

Or can you?

.010" jewelers saw on 4130! Yahoo! If you ask the experts, can't be done. Glad I am not an expert. 8)

Tail feather bits done. Redid the hinges four time until I liked what I had. My friend wanted to use AN bolt all the way around but you have to "engineer" a bit to get them to be usable. Original dimensions don't allow for actual assembly clearances. But issues resolved, they came out nice.

Don't forget a thin washer under the head and a standard one under the nut to prevent galling-your work looks impecable!! :D

The header configuration threw me. looks like, from the photo #1 & #7 (thinkin' normal SBC V8) are scavenging each other and #3 & #5 scavenging each other and I figured the injection setup was some sort of local organizations carburetion limiter-850 H.P. IMPRESSIVE!!

For sure. My guy is a qualified A&P and CFI. I'm just the metal bender in the dungeon.

When these engines came out, they shortened the small block by 4.4" the bore center spacing. All else stayed the same. So I took a Hilborn V8 manifold and sectioned it and welded it back together, then massaged for appearance. These were 240" and could run 57" of boost. Torque up the wazzoo. Revs to 9500 in 1979. This fit a Lola GTP driven by Danny Ongais.
