I cant remember where I bought it. A google search for mill z axis dro will bring them up. I have an odd enco mill. I bought one for a full size mill. As you can see there was a little adaptation necessary. So far I’m happy. I can hit depths in blind holes with it.It ran me around 100 bucks. I...

Wanted to publicly thank Gordon for the engines. He was easy to do business with and understanding when I had an unexpected delay in the process. I’ll post the engines up as I get them done. Dave

Danuzzo, Check out this on YouTube Tubal Cain builds an oscillating steam engine part 4/5 at minute 18:00 he describes how to locate the ports with transfer punches. worth watching the entire build, that’s how I built mine. He gives dimensions in part 6. I drew up a set of plans and wrote an...

I’ll look for the video that I used as instruction covering just that. Works out to be very easy but stressful because of the potential to need to remake parts. Give me a few hours and I’ll get back to you with it. Dave

Danuzzo, Couple things I found helpful. Make your piston to fit your bore. It’s much easier to make a new piston than a new block. I polished with compound to get a fit that pops when you cover the ports and pull the piston out. sand and polish the mating surfaces between the block and the...

I got mine on amazon. But they are available from multiple sources. I have volumes 1&2. There are at least 3 available. I’m very satisfied with the books. Step by step instruction and full drawings showing every dimension you need to know. Between the two books I have several years of work if I...

Flame eater from “steam and sterling 2” is next in the list.

First engine. Air powered wobbler. Got the plans and instruction from mrpete222 on YouTube.

thank you

okay im new and i read the thread. i have a question: is a dividing head the same as a rotary table with dividing plates? which one of the two is required to cut helical gears? they seem similar, maybe comparable, maybe even the same. thanx for your answers dave

Andrew that could be a problem for me. i substituted a quart paint can for the tin of sweets as im not interested in importing a can of mints just for this project. on the other hand I'm substituting Styrofoam for the displacer so it should be less mass to move. we'll see how it goes. i can...

worked on the stirling some more. glued the rubber diaphragm in place, used a glove the first time: then i tried a rubber diaphragm, that worked better. then i had the bearing problem, which i fixed with a dremel tool: I placed the rivets to be used as crank shafts and crank pins in my drill...

nomex wont sustain combustion on its own under most conditions, but i dont see it being appropriate here. i don't think it would do anything useful with molten metal. as to kevlar i dont see it being any better under this application. according to...

so i had some time today and got some of the thing done. cut out all the parts and glued up most of it. lots of sanding too. drilled some holes, if you use this mdf stuff for anything make sure you use a backer when you drill. painted it pics attached

everyone learns lessons, some people do it the hard way. thank you for sharing your lesson so i may choose the easy way. i was thinking heavy leather boots with a steel to for casting. should i be wearing steel foot covers too? thanx dave
