Maybe my eyes got crossed as I was measuring but the piston pin offset on my 94 mm Mahle pistons is approximately .115 (29mm) This seems like a lot and will...
Never mind, the offset is actually .0575. I was really taken back by the first amount! In my excitement I forgot to divide the figure. OOPS! Jeeez! At the...
I saw this engine and was wondering about using it in a WW I replica. Specifically a Sopwith Camel, but any round engined plane. I noticed most of the...
Right about now everyone's pocketbooks are stretched! (Thanks in part to some maligned pilots) How big is the plane that you're wanting to put this in? If it's...
Hi Jim, I noticed in your message (attached) you mentioned using 94mm pistons. Do you know if the R-220 plans specify 85.5mm or 94mm? I've been unable to find...
According to my parts list, it calls for 1600 cc VW pots. That is 85.5 mm bore. As the case for the R180 and R220 is very much the same and that the pitch of...
Jim Using Jack's 180 on a Fisher Celebrety. What does your Dyno say about the five? In final stage of mounting with plumbing and speed ring. Keeline...
Sorry, I don't have a set of the seven cylinder plans yet. Here's something which may help. It's very likely that 94mm cylinders are not on the menu. One easy...
I put some screen captures of Dyno 2000 in the photo section. Some of the dyno simulations were run with my valve timing/size specs and others were done with...
Jim, I need to build a tool post grinder, and I assume thats yours in the pictures... Can you put up or email me a bigger picture (or plans!) if you have them?...
That's my toolpost grinder all right. Someday I might even splurge and make a protective cover for it. For now I keep very clear of it and make sure that...
Atlas tool Company made a great little tool post grinder. I've used one for years. You can find them at good prices on e-bay occasionally.. I use six inch...
Jim, If you want to frighten yourself to death, go to a shop that rebuilds and grinds auto crankshafts. There is something inherently insane about standing ...
Most important thing to remember about grinding wheels is the RPM rating.. If it isn't marked then don't use it.. I generally pay $150 - 600 for diamond...

The idea of using a diamond wheel is very enticing aside from the cost. Up until your post I thought diamond wheels were soley for use on carbide and other...
The beauty of using diamond wheels is the "sharpness" of the abrasive.. There is very little heat build up and no galling. I regualarly hold .00001". I always...
Here's a picture of the prototype heads for HCI's seven cylinder radial. Remember it's a PROTOTYPE meaning that it may not look great but it will satisfy the...
... can ... I ... Andy, Have you been able to come up with anything on the heads for the R-220? Anything you can do will be appreciated. Please let me know. ...
Has anyone accumulated any significant time on the R180? I'm curious about the reliability and maintanence problems of the design. Also, could someone give me...
hi i was wondering would a 9 cyl radial be easier to built that a 120cc v8. i allready have v8 plans but no casts. in anyone can help please do so thanks tom...
Where can you find plans for a v8? Can you get plans for any other engines? Robb, ... __________________________________________________ Do you Yahoo!? Yahoo!...
Hi Tom, I'm like Robb, were does one find drawings for a V-8 and is 120cc a typo or is this a model engine? As for ease of building I'll just say one word in...
Howdy-You are wondering about if you should try to build a radial engine. Well I went through the same kind of thinking, as I have never even turned on a...
I've been watching posts on this site, waiting for someone to respond to "whammy666's" question about accumulated time on the R180. Is there any reason why...
As it sits there are a handful of people who have working examples of HCI radials. Jack and Andy at HCI could tell you the experiences of themselves and...
Here's a roundabout answer to your question. It seems that you and I started at the same point. Bear in mind that the plans I had have been revised since 1997....
Jim: Jack and Andy built SN-002 for me to install in my Nieuport. It is installed and I'm currently in the process of installing fuel injection after two...
