Hey Nick, first of all, where did you find my old video of my Buckman Beam, I thought it got lost in cyber space. It's not showing up in my You Tube library.
Non of my old ones are.
I like the safety stopper you made on your's. I'll have to try it maybe with a spit shot and a thin bead of silicone.
On my beam engine the weight arm is high up(see pics) so I made one with brass tube soldered in side another, soldered shut, a slit cut for the arm and a
slice of silicone tube for a gasket. The stopper, weight, and steam line was all that was missing when I got that one.
I didn't make the stopper, mine came with it, but I do have to make 5 or 6 someday...
Your old videos are under the youtube name "heyfugop" and your new ones are under "Thomas Metiva"
