I like your sliders Sumo:
Where did you get them (Link?) and what are they rated for, Do they come in different lengths . . . Bearings etc?
I am doing something the same but different. I targeted a 36" top of counter hieght for mine.
You could easily replace that OSB with a nice peice of metal of some kind, fire-proof /durable out door finish and rust proof . . .
Also curious on that fender flare piece : where from, what material etc.
LQQking good,
Martin
