MY TAKE ON RUDY'S RADIAL
« on: August 25, 2021, 02:15:50 PM »
After seeing some of the recent builds on Rudy's radial, I was inspired to make one myself.
However, I wanted it to look a little more like the real thing. So I modeled it up and started adding the details to make it
look more prototypical.

Time it start making chips!

Thanks Chris.

Yeah, his design was a little too plain. I think this will wake it up.
I don't know when I will actually start on it. Maybe a piece here and there.
I've got too many paying projects in line right now.

I've build the ubiquitous five cylinder wobbler radial too.

I see these as a build up to a "real" five or nine cylinder radial. Definitely on my bucket list in retirement.

Your design looks really good, Sid. The exhaust stubs are a great touch, I wish I'd thought of that!

If I had planned the touches I added to mine from the start, I too would have put the pushrod tubes at the front. Mine are a little bit hidden at the back, but it was the easier way to incorporate what was more or less an afterthought.

Ron

I also added a bunch more fasteners. Again to make it look more proto.
Going to have to be patient doing all those 2-56's!

Here is the start.
40 2-56's.
No errors!

Center case came out great - thats a lot of tapping!
Anyone ever try a double-acting version of an engine like this? Would need a lot of redesign. Anyway, this is looking great!

Excellent work!  That's a lot of tapping.  I believe I broke a tap off in that part when I made mine.  Glad you were able to complete it with no tap breakage!

And you even did extra holes above and beyond the plans!

I used a tap guide, starting and bottoming taps and butter cut for each hole.
Also, I take the part to work and at lunch time, or when in a online meeting I'll do a couple of holes.
Basically, take my time doing each.

Here is the front housing.
I'll be using shielded ball bearings instead of the bushing.

No, it's 6061 aluminum.
I'm debating to glass bead it (to look more like casting) or black anodize it???
Most of my other engines are black anodize.

Don, Chris- Thanks!
