I've got one tucked away Peter. Cheers Dave that good to know Had a couple of sucessful days in the shop. Made the crank webs, they are of the pinch clamp type so you can get them on and off due to the design of the engine. First drill the holes 2 with 8mm crank pins 2 with 6 mm crank pins...

Thanks Guys Started back on the engine for a little while at least. Finished off the rest of the linkage Made the piston today its a job I've been putting off don't know why I guess I just had a funny for doing it. I liked the idea of making the piston out of PTFE, the main reason is its...

That,s worth knowing Stew

Looking good Tel Increasing the bore is a good idea, at 1/2" I think they are a little under powered. Watch out for those Hex bolts fouling the cross head guide I swopped mine for slotted cheese heads. Stew

I got very close to these sizes when i ran it through my maths (.438 and .748) for 1/8 and 3/16 ports. If you've done the cad simulation and and it looks OK it probably is OK Brian, we can keep our fingers crossed and hope the black cat comes up trick. There is more than one way to skin a...

Brian Have you worked out the throw of the cam for the slide valve. ??? Just ran you're figures through the vormula I use and I'm strugling to get the same answer as you, or see how the valve would work. I take it you're trying to use standard imperial cutters of 1/8" and 3/16" I think these...

Tel:- that how i would have done it but these things are so small I thought I'd have a bit more to grip on, I did keep them in pairs by wiring them up after i'd drilled them. I thought I'd got lucky bending the first one, I was right putting those bends in was a bit of a headace. I was using...

Thanks Guys You know I looked at this three times before i twigged on about the ck not x bit:- I just can't see these things :big: :big: :big: Some more set up pics Turning the taper and 10ba thread problem was getting the compound back to the same pint ended up putting a stop on it, you...

A friend ask me if i could make hime some Bibcoxs for his 1 1/2" Allchine traction engine, Bibcox is the old fasion name for a tap. This is the drawings Tiny little buggers arn't they. First make the D bit Slew the compound over 3 deg and turn a taper on a length of silver steel, give it...

Cracking Job :bow: :bow: :bow: Stew

The cold has kept me out of the shop for the last few days or so, to keep my sanity i've drawn up this engine. It a type that found a lot of uses as in the yourkshire woolen mills, but it can trace in origins back to the North East coals feilds where it was one of the earliest types of winding...

Wow that's a surprise, Thank you all very much Guys I feel greatly honored. Stew

Hi Brian that looks real good, i like your idea of actualy putting an engine to work, I've long toyed with the idea of coupling an engine up to a rolling mill. I thought my popcorn engine was a little small on the cylinder bore, I put a pressure gauge onto the air line to see what it took to...

Great build Jason very informative, very interesting use of adhesives and materials. Thanks for showing Stew

Jerry My over crank had excentrics inside the crank web. I just made them solid and pinned one of the webs so that the crank could be split, once everything was up and running and proven, I simply pinned the web in a more permanent fasion. Hope this helps Stew

Thanks for your kind comments Guys. I was realy quite suprized how soon the article was published after i submitted it. From comments made by the editor on the forum though, I think they are running short of suitable articles. Brian:- I understand what you mean, there is a couple of guys that...
