LMS Oscillator
« on: August 31, 2012, 11:58:19 PM »
Well, it's a runner! I built the LMS Oscillating Engine.

http://littlemachineshop.com/Products/Drawings/2593OscillatingEngineAssembly.pdf

Not really complex, but it ran the first time I put air to it! Not pretty yet, but I plan to bling it up a bit.( This is the engine I asked about making a double acting, got ideas for that, too!) Spent the afternoon running it in and tweaking it. I think I'll decorate the base and upright with "engine turning".
I only have a very loud portable Hausfeld-Campbell portable air compressor, so the requsit video had to wait untill I finished a home brew adaptor to run it off of a computer tech's canned air supply.
Wow! Those cans of air don't last long!
I tried to make a video of the engine using the canned air, but it didn't come out well. I'll try again tomorrow.

Great job Chuck, there is nothing more satisfying like seeing your first runner. Keep up the good work.

Nice Job Chuck.  I'll bet you had a lot of fun building it.  Nothing like a runner on the first try!

A good start Chuck, If you are using canned air make sure of its contents. Some of the cans used are not air but butane. I found this out while using canned air from a air brush kit to test for leaks in a burner design. I spilled the cup of soapy water I had Ben using and rather than go upstairs to replace it I used a BBQ lighter flame. I almost had to go and change my pants when the "air leak" caught on fire. On looking at he can of propellant I did notice a very small notice that the product was flammable. Why don't you use a long hose on the compressor or let the pressure build up in the tank and then shut the compressor off.
Regards,
Gerald.

As promisced, a video of the LMS Oscillator running, although there is no sound. It's running of the air duster can at the left. It would only run in a few seconds burst before the canned air pressure dropped, but it was self starting!
Now to strip it down and bling it up a bit.
By the way, this is my second running engine, and my third build. I think I'll rebuild my flamelicker that I couldn't get running next. I did a poor job on the cylinder and didn't have any cast iron to remake it.

I'm working on the bling. Have been sanding the aluminum base and upright on a glass plate from a scanner, with 340 and 220 wet and dry. Some of the corrosion spots and deep scratches wont come out. Do I need to go to more coarse wet and dry? I plan to use "Machine turning with wet and dry glued on the end of a dowel, and then clear or color anodize. The flywheel
I'm happy with except I may paint it between the rim and brass hubs. Any advise?
Thanks for the comments guys...
