Re: Free and easy to learn 3D CAD
I've spent the better part of the last three months trying to wrap my head around this computer 3D drawing stuff. It is a very tall learning curve for me. BUT, all is not lost.... I tried, FreeCad, Onshape, Tinker Cad, Fusion and Solidworks. Hands down the easiest for me to learn was Solidworks. Not...

Re: Release agent question
Wish I could take credit for it, but I am a student in this group, so I do help a bit. This is part of the castings for a hit & miss engine.

Re: Release agent question
We use CRC silicone spray in our core box to release sodium silicate and sand core hardened with CO2. Our core box and patterns are 3D printed with 175 filament.

Do you still have this mini for sale? What is the price? Can you post a photo? Do you have a good guess on shipping weight?
Thx Scotty

I worked as a jet engine mechanic in the Air Force, (engine shop, flight line, phase docks and test cell) and subsequently for a pipeline company that used acft deritivative engines to drive the pumps.

Re: 'soft' silver solder...
The silver bearing solder you want is 95% tin, 5% silver. The hardware store stuff is 95% tin, 5% bismuth, or something like that, and is crap to use. The commercial names are Harris Sta-Bright, All State 430. Especially for brass or sstl, the liquid acid flux sold with those should be used. That a...

Re: MEG Wendy suspension
It does help to understand the potential problems and reasonable ways to approach changes.

MEG Wendy suspension
A question for any of those who have worked on the Wendy suspension, or any of the Hackworth Gear types I guess. The plans call for .250 x 2" neoprene everywhere neporene is indicated. Any neoprene I can find is very very soft. So, I found hockey pucks to cut up. Is that too stiff? Considering the s...

Re: Propane oriface size
The Marty burners that I'm playing with use a #71 which is what the instructions call for. He goes on to say .....as close to .026 as possible. Now, he is working with 1 psi and up to 5 psi. One nozzle. The two that I have made so far appear way too rich, but I suspect that is poor machining and the...
