Thm: Well done Andrew :) Kind regards, Arnold

Hi Marty If you can add an image of the section on the print showing the part with the mystery passage, it will help others to help you. Kind regards, Arnold

You're doing very well indeed Ed Thm: Enjoy your vacation :) Kind regards, Arnold

Ron / Stew / Stuart, thanks for your original responses :) ;D You got it Bez. But not so much because of the cylinder and/or piston expansion, but more because of steam efficiency. A cool engine running on steam is less efficient (or uses more steam) as it cannot use the full expansion effect...

Hi Ryan Clamp one end of the sheet in your mill vise, and use another vise or something that can clamp over the other end to twist it straight - that should straighten it up fairly well and evenly. Kind regards, Arnold

Thanks Jan :) - Yes, I agree there's a certain level of pleasure in making the really small bits... Sometimes it borders on masochism ;D Hi Ryan, no problem; please ask away if you have questions :) Yes, I could have threaded before parting and run each nut over the tap afterwards - in fact...

:-X I didn't get a chance to update yesterday evening, but it's a bit boring anyway... I just made about twenty 2mm washers x 0.2mm thick from some 4mm brass rod. Stan (sshire) mentioned earlier when I made some other thin washers about a method I'd shown in another thread, but I'll just show...

A very good question Ron, and one I'm also curious about as to how it's done. I know how to go about stuffing cylinder and valve rod pack nuts, but the actual piston packing has me in the dark as well. Kind regards, Arnold

Good start Dave, and nice tips :bow: ;D I love my faceplate; though it does not get used all that often, it's indispensable for some jobs. Kind regards, Arnold

Lovely work Dave. I particularly like your round-the-corner drill :bow: Kind regards, Arnold

Aye - aye :bow: Kind regards, Arnold

Thanks Ron :) - The posts will pretty much be weekend-to weekend now; a sudden cold spell has hit, and I tend to stay out of the shop if the machines turn a cold shoulder ;) Ed, thank you :) - I'm glad there's something of value to you in the posts. I very nearly built the #29 as this build, as...

:) Thanks Bob - Sorry for the late reply! Today I interrupted my current engine build to make a bit of tooling that will take some pain out of the engine build. It's something I've needed on a couple of occasions, and never bothered to get around to - even though it's simple to make... A...

Nice one Brian Thm: - congratulations! ;D Those fiddly bits - they do take a lot of time... Kind regards, Arnold

;D Well done Pete - those popping noises sounds _really_ promising Thm: Kind regards, Arnold

Thanks Dave - scratch.gif Now, why didn't I think of that :big: Something to keep in mind for future fixture plates; it'll be nice to spread the work! Brian, thanks :), they were easy to make. The biggest concern I had was forming the dome with the bits just engaged by the threads. The simple...

That's good going Manfred Thm: I like your coil winder :bow: Kind regards, Arnold

That's looking really good Jason Thm: Kind regards, Arnold

Hi Peter. No, drilling and tapping the valve itself will not work; the valve must be able to "float" on the valve rod, as it needs to be pressed against the valve plate by steam (air) pressure. Kind regards, Arnold

Hi Rich Yes, they're most likely all from the same factory with a bit of re-branding; the unit in your link looks exactly like the three axis version of the one I bought from TheDROStore.com. I'm enjoying it; and it's really easy to use. Kind regards, Arnold
