Thanks For The info. Very valuable to me.
My current HF bench, I bought when I started this hobby, with regular casters as I have to have everything stowed away when I am done so my wife can park inside.
Even with the regular caster, I get stuff rolling on the floor due to the unevenness and v grooves on the concrete .
3/4 of the floor sound pretty good. Maybe “embedded” permanent on one side and “lifting” caster on the other might work.
I guess I will have to try when I build.
Thanks Again!
