I would like to have turned the Rollers from Sycamore or Beach but I dont have anything suitable the only thing I do have is Oak not my first choice but should be OK.
The piece of Oak is about 7 feet long and 6" x 4.5" that will be OK for 4" x 20" Rollers
I thought cutting this size of Oak on my new Sliding Mitre Saw would be a real test but it went through it like a hot knife through Butter.
A couple of passes over the planer does the trick.
I will be turning the Rollers this will be on my update Tomorrow
