Hi BlueJets, I ordered 5 single boards today from JLCPCB yesterday. I'll update as parts start to come in. Jerry

Brian, I wondered about the valve guides and creating the valve seat in the aluminum. The press in valve guides that I like are the ones on the Howell V-Twin. They incorporate the valve seat at the bottom of the valve guide. Dont forget to drill holes thru the new valve guides for the intake...

BlueJets: I'm trying to order your V2 pcbs at JLCPCB. When I upload the gerber file, I get the attached files. Do I select Panel by JLCPCB? 2 row and 2 columns? Looks like JLCPCB wants to put 5 pcb on each panel. Thanks, Jerry

Here is a build that Blondihacks did.

I built the MLA Die Filer. Fun to build and works great. Highly recommend.

PM sent!

Hi TinkerJim, As far as tubing, I used what was specified the 1.312 OD x 1.072 ID for the power cylinder. I like the leather cup because its something we would of had back in the day. I'm interested in your offer for the leather cup. Thanks for the gasket material part number. Amazon...

Hi TinkerJim, Thanks on where to buy the bearings. They arrived today. My next question is the flexible leather cup seal. Do you have a good source for the seals? Any recommendations on the gasket material? Thanks, Jerry

TinkerJim, I'm fine on materials. But I'm wondering if you have some bearing part numbers. From what I read so far, the bearing plate needs bearings and the power crankpin. I do have a question. On the engine base, you have a .332 dia hole that you drill and tap for 3/8-24. What diameter...

Hi Jim, I have the Book Moriya Major coming in two days. I had never heard of the Moriya before, but what a cool working build to have in the workshop. I would be interested in your material offer. I would also pony up some spare change if needed. Thanks, Jerry

Looks really good. When I wind springs, If I need 4 springs, I wind them all at one time. That way there all the same and you just cut them apart. Jerry

Bob, Sorry to hear about your injury. It happens, just be glad it wasnt more serious then it was. Thanks for posting your CNC adventures. I love seeing the fixtures and how the machining is done. I'm self taught also and use these post for learning. I'm also applying my new CNC skills to...

Progess was the only model I received without dimensions. But Mrpete22's video were great on teaching me some techniques. I also enjoy Mrpete22's sense of humor.

go to 18:49 in the video. I watched his series of videos to build mine.

Watch this youtube video on building the Progress. If I remember right he has the dimensions in the video.

None of the cylinders I have received have been already machined. Which model is it?

Terry, Your work on this engine is awesome. I'm really interested in trying your epoxy method of holding parts while machining the part. What do you use for an oven? Can I use a convection toaster oven? Jerry

I just had a chance to test PM's customer service. My PM-1340 which I bought in 2018 had the DRO fail. Called PM, John had me perform a manual test to confirm the read head on the DRO scale was not working correctly. It failed of course. New part was ordered and received at no cost. I...
