Mine works pretty well, but I'd still make some changes. It's two oak stair treads glued together and formed with a combination of my table saw, dynafile, and big ass rat tail file. Having it up on the wall is nice since it's out of the way. I got a wheel from McMaster Carr I think, then fabbed the rest up. I use a U shape piece of steel with a nut through it as a hold down, then slide a curved piece of a section of gas pipe in for support. I could take better photos, but this is all I found looking through my pages. I use a piece of rod as a stop which is adjustable according to it's placement by holes I drill. Simple and works. Before I made this one I went through about 3 that ended up breaking. Aside from the green wheel, everything came from Lowe's or Home Depot, I can't remember which.
