“Easy to learn” should be banned from the English language. Nuclear Physics is easy to learn too, for some people. It depends on your background and ability. I find Fusion 360 impossible to understand. Same with Nuclear Physics. Can anyone explain the difference between Fusion 360 and Inventor?

If I could borrow a time machine I would head back to Tesla’s era and whisper in his ear 1 cent, 1 cent. George Westinghouse offered Tesla a fairly high license fee for each kw sent down the lines from Niagara Falls. The partners in the company complained about this and Westinghouse had to go...

If you can grind steel valves with toothpaste I wonder what it is doing to your teeth?

Hi Paul. I am an RC fan as well. Just tried printing my first model on my new 3D printer. Really want to build my own engines. I bought a lathe some years ago and now that I am retired and active in the shop I regret what I bought. Of all things make sure the lathe you buy has variable speeds...

I guess I should take all this advice to heart and attach the foot pedal to my new machine. It is a stick/tig/plasma machine and works very well in all modes. I just find that focusing on what my hands are doing while tig welding doesn’t leave enough brain cells available to add foot action. Oh...

Right, three is a good start.

That is like the speeder handle on a micrometer. I bought a used 1” Mitutoyo micrometer on Ebay. It is an expensive model but this one is pretty beat up. It was very had to turn so I took it apart, removed the adjuster and opened the fingers that tighten on the shaft. This reduced the effort...

Interesting about the ratchet idea. That will be a bit of a head scratcher. This is just a little plastic turntable that you can't open up without breaking. Not made to repair. A ratchet would have to drag on the side of the moving table and prevent it from backing up. So mount it on the frame...

Its called 3DF Zephyr. I tried a number of different programs and this one is by far the best. Great tutorials on the web site. You get a free copy that is limited to 50 pictures. You are supposed to use many more than that but I have had good luck with 50. I intend to buy their minimum level...

That is what I want. I want it to run the same direction every time I step on the pedal. There is no reverse switch. Just on/off. The turntable always comes to a complete stop as I take the picture.

I am really interested in an electronic lead screw for my King lathe. Have to get some time and study those You tube videos. There is a nice series on installing a variable speed motor on a lathe. The fellow is using a Grizzly but it is identical to mine. What a pile of work. And a lot of...

I want to use 3D photogrammetry to model engine parts, print them on my 3D printer and try lost PLA casting. I built a light box and gave it a try. Works great. I copied and printed several various objects around the shop. The process involves taking lots of overlapping pictures of the object...

That one looks way better than the 7X14 lathes. Nice little lathe. No gearbox so you would have to change gears to change feed rates.

So nice they are sold out.

I have a simple King 10X22 lathe and as I get in to the hobby and learn more there are a few things I really want. The main thing is electronic speed control. Changing the belts on the King is a long and frustrating job. So I just leave it on a spindle speed of 520 and do everything with that...

I checked Amazon for Alec Farmers book. One was listed for over $500 and another for over $2000. Just ridiculous. Are these people serious or is this a joke?

I groan when I think about moving again. Done it too many times. The old saying “three moves as good as a fire” is very true. Move all your tools yourself. I discovered that the people who come and box everything for a moving company like to take souvenirs. Like an outboard motor and every tool...

So other than work hardening does copper return to a hardened state with time? I am wondering about strength if the end plate was annealed for final shaping but still soft when used in the boiler. I guess this begs the question about silver soldering. If you get the copper hot enough to flow the...

I have read all the threads I can find on annealing the copper end plates of small boilers before hammering them over a form. You Tube videos show the fellow heating the endplate up to cherry red and dropping it into water. The main thread I could find on this forum had an entry saying you can...

I just want the cylinder and piston assemblies, don’t need the rest of the engine. Have you got odds and sods of spares for sale?
