Well, still working on center. Photo needs explanation. The green line points to the silver dot which is the center both using a center tool and using the DRO to get center from the outside of the hub. This was taken at the same height in all locations thanks to DRO. The lines from the tool...

Not that I am aware Phil, will go back and look thru the spam folder. jackmartin29@gmailcom?

Well the last weekend in July and the first weekend in August he will probably be at the Great American Steam up in Brooks Oregon. Pretty cool place and well worth the trip if you havent gone. I saw it last year. Yes, Gary is not at all hesitant to give advice and tips. I have enjoyed every...

My head won't wrap around why just going with the outer diameter won't work. But I will do things the way suggested.

I have now spoken to Gary and he says.....Since I have placed the counter balance weights on the crankshaft the loss of material on the flywheel will not be important. Therefore indicate off the center parting line at the spokes and do the whole thing over.

Phil, I have considered this, but I would rather indicate off something that does not move, and fix the table to zero. You have the concept I need. I do think Marvin's suggestion will be easier and more accurate and eliminate the rotory table completely. I do not want to re do the outer...

You know Marvin, that is a good idea, as if I can stretch things out from the quill, instead of only being able to go from center, that I could reach both sides of the Y axis. Since I know I am off, I am thinking the only way to have it look right is to go from the outer ring. BUT I am not...

Well. Deep subject, right? Lots to discuss. First though, I need to shout out to Gary Martin, who reached out to me on the setup for the flywheel yesterday. He took the time to try and post here and had problems, so he emailed me to contact him. Unfortunately, it was too late, I already was...

came out good

I was planning on using an arbor, but good point that I had not considered.

The belt pulley polished out well and started on the flywheel

These tiny bubbles show in approximately the same area. Just not sure. At this point waiting for Prismatic Powders engineer to get back to me, customer support went to them because they didn't know what to do or why. As I look at the drawings for the flywheel, I may have to do some milling...

Yes, thank you for your thoughts. By using the 4" diameter pipe piece, I am supporting under the spokes evenly and clamping as close to as perfectly over the pipe section. Thusly, I don't get any change if I push on the outer wheel at one spoke or another. .. Still looking at it, thinking on...

Forgot the photo or it didn't upload apparently.

Unfortunately I am not good at describing something like this. Though, I think I have it. The part is clamped to the rotory table. It is supported on the spokes by the 4" diameter spacer. The center hub (best I can get with bumps and such on the hub...tho filed) is .0025 +/- so a total of...

Not having success with this. Let me back up, 5" rotory table. Centered to spindle of mill and DRO zeroed for later. I have a dial indicator in the mill spindle for the center hub of the flywheel. I have a dial indicator on the outer ring on the "up" side. Now we all know that the flywheel...

Not sure how to do the flywheel at this point. Researching ways to do it on the mill as it is too big for the lathe(10.5). Several ideas for mill are feasible, just not sure which is going to work or not. Cannot use a 3 or 4 jaw chuck, none fit the flywheel that will fit on the rotary table...

POWDER COAT IS NOT IMPERVIOUS TO CARB CLEANER/LACQUER THINNER. Oops

Hope all is well with everyone. Crank finished, cleaned up and powder coated. Did the piston rings today too. Crank turns nicely by hand, freely, getting about one full turn with a minor 'flip' on the shaft. Now, I am going to put the flywheel and the belt pulley on the same shaft which...

No I did not, and tho not done, it is straight. Fits well, turns easily. Still cleaning up and polishing to go.
