Incredible work. I agree on the sleeve valve - the wow factor on this is hard to beat, and about the only way to go from here would be a Bristol Centaurus or a Napier Sabre.

I got my hands on some 8/4 african mahogany, which was glued up a bit oversize, then thrown in the mill Roughing and finishing passes were done with a 1" ball nose I got a tiny bit of tearout on one top corner but the rest of it was fine after I changed the lead-in in...

So I've been remiss and neglected the thread, and finished the project in the meantime, so here is a whole raft of updates! Next up, the valve, done out of teflon. This made use of a very long and scrawny 1/8" HSS two flute I found laying around, which would have been completely awful on...

Update time! I've been doing lots of machining and not much sharing lately, so it's time to remedy that. Picking up where we left off, once the forks were finished up, it was on to the cylinder heads. For the lower head, the original design was modified to use a 6 bolt pattern to mount it to...

I'm definitely going to be following this closely - I really like that engine. I think my next undertaking will be a Stuart No. 1, but this is very appealing as well. I may just have to build both of them :)

Now for the crank disc! I haven't done much with stainless prior to this, but I selected some 303 for ease of machining, used some nice fresh tools and couldn't be happier with the results. I started off with a 3x3x0.5 piece of material which was drilled with a #3 for the 1/4-28 crank...

Update time! I've managed to complete the base plate and several of the brass components since last time. First, a few modifications were made to the design, including fancying up the piston and conrod forks and changing to a hexagonal bolt pattern and shape for the lower cylinder head. Here...

Got some more work done over the weekend finishing up the parts shown above. The hold down lugs were milled off of the leg, and then the pivot pin holes were located and drilled. Next, the bearings were bored, skimmed, drilled and tapped. Boring bar to get everything good and...

Thanks for the kind words. I made some small modifications and figured out the rendering software, so here are a couple more pictures of the cad model. I added the center cap to the flywheel and redid the eccentric strap. I changed the brass toppers on the arm and column too, but I'm still not...

Howdy folks. Now that I've spent a good deal of time on these boards admiring everone else's handywork, it's finally time to start making some chips of my own. I've been doing various things in machine shops for a number of years, but this is my first foray into model engines. Elmer's #37 caught...
