My current 6" contact wheel on my combo platen has a ton of wear, 2 large grooves in the surface and smaller ribbing after a little over a year of hobby use. Most of the use is profiling out and shaping handles with a little contact wheel profiling, but I dont think it should look this bad already! It uses 1/2" bolt for a shaft so I am looking at the usaknifemaker poly 6" wheel to replace it. Any other options out there that arent crazy expensive?
