I live near Frederick, MD. Pretty much the center of the state. I could meet you towards Baltimore possibly?

I didn't build this one, I acquired it a few years ago at a sale. I'm 99% sure it's an "Upshur" engine. ~ 3 1/2" flywheels, no governor mechanism just throttled by hand. Seems complete a pretty well built, but low on compression. I haven't tried running it, it's just been a shelf ornament...

Sold, thanks for looking.

I have an untouched casting kit for the Vaughn sideshaft engine made by Debolt: http://www.homemodelenginemachinist.com/showthread.php?t=25738

Anyone interested at $600? Cheaper than a new Debolt kit, and an out-of-production one at that.

I have a complete and untouched Vaughn sideshaft engine casting kit. Originally produced by Debolt, although they haven't made it for quite a few years now. This one is all there, well stored, and includes all the original paperwork, prints, build photos, brass nameplate, etc. Asking $700...

Or the faint of talent...

You can also just wind a coil in a couple minutes with a lathe and a spool of copper wire from RadioShack :)

I'm still here and still working on the Webster when I have a chance. I had to modify a few small details in my plans. The cam roller retainer, which is basically just a small flanged nut, was supposed to have #4-40 threads inside but the walls were too thin and it kept breaking during...

Although my model isn't running, I do have a number of full-size H&M engines. I buy old motorcycle coils at sawp meets and such for a couple bucks. They're compact, potted to keep out moisture, and they're pretty small. You can use the primary side alone for a low-tension setup or use the...

It's been too cold to spend too much time in the shop at once, but I've gotten a bit more done. I made the valve spring retainers, lapped the valves, and installed the valves and springs on the engine. I made a change to the prints (again) in the spring retainers. I counterbored the top side...

Was that crank left "as cast" or did you roughen those surfaces after machining to resemble cast? What material did you choose for the crank?

I bought mine from CenturySpring. They have a $40 minimum order, so I bought springs for the Webster, the Farm Boy (future build), and a few standard sizes I'll find a use for someday to flesh out the order.

It's not pinned in place until i get the came done, and without it being pinned it slides back and forth into the cutout I made in the baseplate. I don't want it getting dinged up. Hopefully soon it will be installed for good!

Although I found some of Brian's earlier comments on this thread a bit harsh and one-sided I thought the most recent post about roller cams to be informative. In fact, upon further reflection I think my mistake in cam duration will help me because I didn't account for how the roller would...
