There is some extra information in this thread: www.modelgasboats.com/index.ph...=5&id=2352#2352

4-40 seems to work well. I have not heard of or experienced a difference between a shortened plug and regular one. Maybe it does affect it though, can't tell for certain.

I am going to try this with a silicon carbide wheel, and just tack on the cap nut, I could use shorter plugs, I think it would be a neater look.
