Ah, a fellow tinkerer. Best of luck and remember, it's not the finished product, it's the process of creating that is fun.

Phil, The case will (if needed) be machined after full weld. I will do a full measure of it when I have welded some more. The goal is to use as little out Fri, 13 Nov 2009 00:17:34 GMT Phil Dorothy http://groups.yahoo.com/group/HCIRadialbuilder/message/894 http://groups.yahoo.com/group/HCIRadialbuilder/message/894 ... Joakim, This looks really interesting. If this is the final crankcase and not just a mock-up, I wonder if the final machining should be done AFTER the Thu, 12 Nov 2009 23:43:10 GMT joakim.svedin http://groups.yahoo.com/group/HCIRadialbuilder/message/893 http://groups.yahoo.com/group/HCIRadialbuilder/message/893 I took the liberty to create an album for my pictures. - Swedish 7cyl radial Mon, 02 Nov 2009 09:23:15 GMT joakim.svedin http://groups.yahoo.com/group/HCIRadialbuilder/message/892 http://groups.yahoo.com/group/HCIRadialbuilder/message/892 just curious...

We no longer have access to the person who set it up, and we're struggling. Yes, we're still here.

The nature of a "Master Rod" Radial is that each piston "sees" a different crank center and thus a different deck height.

Whenever I am in need of motivation, I just pop in the video and watch you fly your plane.

There are several ways to accomplish this compensation, but this seemed to be Fri, 23 Oct 2009 21:20:42 GMT Damjan http://groups.yahoo.com/group/HCIRadialbuilder/message/883 http://groups.yahoo.com/group/HCIRadialbuilder/message/883 Hello! Can someone tell me why the clinder spacers have different height dimensions (0.440, 0.340, 0.314, 0.395)? 7 cylinder R-220 STARMOTOR.

They probably work OK in a drag bug with forced air
