Offie engine

A great and ambitious project. Very Impressive. I loved the old Indy roadsters before the rear engine cars showed up. 

That's cool Don.  You know when you finish it you're going to have to put it in a sprint car!

Too big!

I have another less ambitious offie for a 1/12 sprint car I am working on, and another for a 1/12 midget, that the 110 ci version.  Hope to get to work again soon on the midget.

Got some more work done.  Polished aluminun Alclad on cam covers, mounted same, and nose engine support.  The magneto is just setting on its mount- have more work to do in it before I mount it.   I have the engine sitting on its wood display mounting, but need to do more work on that, later.

Very interesting project. Looks really good so far Don.

Is there any wiring or detail pieces going on this one?

Oh, yes.  Ignition wiring, fuel plumbing, and fittings for water and oil but no hoses for same.

WOW!! That's really cool! How did you make the fins?

WOW!! That's really cool! How did you make the fins?

 

I started with the basic plates of 30 mil styrene, then laid down strips of 80 mil by 20 mil, alternating one flat, one standing up.  Then laid 20 x 80 around edges to level everything. On left side I cut pieces of 20 mil to fit around crankcase breather pipes, and pieced those on on fins in that area.

Had a big setback recently.  I found I had made the crankcase too long by about 90 mil, and the head hold-down rods would not engage with fitting on head.  Had to saw off bell-housing and in-out box with my band saw, and sand on disk sander the back of crankcase.  Got it all sanded and filled now, and about to glue the two pieces back together.  Pics soon. 

Hate it when that kinda stuff happens. Looking forward to the recovery efforts Don.

Dang!! That looks GREAT!

Got the bell housing and in-out box back on engine.  Got the back of the block repainted.  That was a job because the rest of the cylinder block was a mixed color and I had to mix it again the match.  When I took the tape off, a bit of the iron color on the in-out box came off, and still touching that up.

Working on the mag now.  Also started cutting out the exhaust manifold.  That will be done from a sheet of three eighth's basswood with some small pieces glued on.  I think that manifold will be the hardest part of the whole project.  It will have to be perfect, because I intend to Alclad it and then ghost on some red and blue burned areas.

Okay, here is the picture.  The model is now about a tenth of an inch shorter.  Still blemish on the in-out box, still working on it, another coat of paint.

More problems.  The plastic cap I used for the in-out box just will not hold paint :-(  I am scraping it and will do a new one, maybe a bit more accurate too.  Filling of the scar on the back of the crankcase has become more effort than I anticipated too.  I am putting it up on my shelf of doom for awhile while I do a simpler project (new Revell sprint car).

Been there.....done that. My Arado 234 build took 3 friggin' years because of this same kind of stuff. Sorry you're having so many issues with this one Don. Looking forward to more progress when you get back to it.
