I use Harris Safety Silv 56 for the silver solder, and Harris Stay-Silv white flux. For the torch, when the part isn't terribly big I use Bernzomatic Mapp gas (yellow tank) and use the proper torch head for Mapp gas. For bigger jobs, I use oxy acetylene with a gas weld torch tip. With the...

I found an old article - https://sceptreflight.com/Model%20Engine%20Tests/Atwood%20Glo-Devil.html It shows a cutaway view of the engine. It looks like the cylinder head gets removed, and then the steel finned cylinder, which extends down into the case as a liner below the fins, can come off...

If you aren't thrilled about the D cell setup, do some searches for glow drivers. There are some set up for multiple cylinders, and the systems run on a higher voltage. They control how much voltage goes to the plugs even with a higher supply voltage. The RC world has them in various setups. Dan

The Siamese Bee engine is designed for glow plugs. Glow plugs are 1.5 volt devices. Running lithium batteries are higher voltage than what the glow plugs are designed for. Dan

Great! Thanks a lot!

Yup, just general length, width and thickness. Thanks

Good luck with the Snow! Read all the forum threads for great ideas. Question, anybody have the base dimensions? I'm in Wisconsin, not too far from Speedy Metals. The base is my next step.

Yep, your slip ring looks just like mine, I just used some black delrin because it was there. I threaded the inside and screwed it onto the shaft. Only problem is, to remove it I have to unsolder the wires. Steamchick - I say that I wanted to leave the technical electrical stuff at my old...

Well, when I went down the ceiling fan route, I know that a Bruce Macbeth was already turning one successfully. Plus, I had several old fans at my disposal. By putting my own magnets in, if I found too much load, I could change out for smaller magnets. As a response to K2, I purposely keep as...

I will consider the open look at some point. I ruined one shell and snapped a tool bit because my rotary table simply isn't rigid enough. This was just an experiment for me. I know it can be done, I've seen it before, operating. I'm a retired electrical engineer, and still a rather fresh model...

The first image is what used to be the stator, what got fastened to the ceiling. There are only 2 windings. Selecting one or the other changes the speed. There are 4 wires, 2 for each winding. The wires are fed out through the hollow shaft. This becomes the rotor, what gets coupled to my...

I am going down the same path using old ceiling fan motors. I'm still in the experimenting stage. I attached the fan stator, which is normally stationary in a fan application, to the crankshaft of my Bruce Macbeth, using a rubber coupler. The surrounding shell, which is usually the rotating part...

I have an older Bridgeport, 60's vintage, with the motor that specs at 1730rpm at 60hz only. I usually leave my belt at between the second or third belt speed and run the variable thru the VFD. I never run faster than 60hz on the motor. I usually run 1/2" or 3/4" tooling max and I don't take...

OK, turns out that Aquafina bottled water is RO water. No wonder I can't stand the taste! So that plus regular good old green anti-freeze is the coolant of choice, and I need to incorporate a drain tap on my engine cooling system for draining after a show. Thanks!

I finished a Bruce Macbeth engine about a year ago. I ran it at Cabin Fever this year. I used Water Wetter as an additive to distilled water for the coolant. I left the coolant in the engine afterwards, thinking that the Water Wetter would keep corrosion at bay. WRONG! This pasty white stuff...

I know Roy has them listed on his website, but since he's attempting to ramp down his business, I did some extra searching, as I'm gathering up parts for a Snow engine build myself. I'm ordering from Roy for comparison, but I found this -...
