Well done. You’ll get the bugs out soon enough. Great community to help us along.

And you only did enough for one engine? Lol. Nice job.

Great pictures, some very nice setups that I hope to use in the future. Thanks for the post.

Beautiful job Jack. Can’t wait to hear/see it running. Thanks for helping me along the path on this engine. Karl

Jack, thanks for the tip on the depth of the cut in the clevis and mis match on hole sizes. Got my clevis, rods, and nuts done, now might have to change them a bit. Working on the explosion chambers and just noticed that you had 8 studs on the top, my drawing (and now the parts) only have 6. Was...

Great job Jack. Just started the clevis and rods to go along with the eccentrics. Making them to print dimensions is challenging, wanted to just use 3/8 or 7/16 square stock, but I’m making them to print. The exhaust chambers will be coming soon. Thanks for the details.

Nice going Jack and thanks again for your help. Guess I know what parts I might be making next. Won’t be in the shop for almost a month so will likely forget by then.

Jack, do you have a picture of your “under cutting” tool? Good progress on your engine, I’ve got too many other things going on right now, Mery progress is suffering

Jack, I’m at the same spot with the eccentrics. Wanted to bore and undercut on the lathe, can’t figure out how to hold them. Maybe on the mill in a vice and a special cutter to do the undercut.

Jack, did you do a scratch cut first? Did you cut full death in one pass?

When I cut my 150 tooth gear I used packing plates on both sides of the gear blank to reinforce it to reduce vibration and cut full deapth in one pass. I did do a scratch cut first to make sure my indexing was correct. I used the specific cutter, I can’t remember which one (#1 or #3).

Jack, enjoying your build as I’m also building a Mery. I had the required cutters to cut my gears so that I didn’t need to make the hob, but I’d like to add that skill. Could you please provide a link to the information you used?

I can see all your pictures on an iPad. Nice work.

Just googled it.PEEK 2” diameter rod, 12” long. $273 plus s&h

Here’s a picture of Rich’s polisher, been meaning to make one since my visit. Rich, hope you don’t mind me posting this.

Steve, those are looking good.

I’d look on Craigslist, or sold items on eBay. Maybe there’s a model engineering club near you that you could contact. Half of new price is usually a good starting point. I might be interested in some of them, where are you located?

Phil, did you use rattle cans or bulk paint and thin it? I just started to machine mine and I’m already worried about painting.

Phil, beautiful engine, I’ll be looking at your build for sure. Thanks for posting.
