For my workbench project I think about what kind of feet are suitable. Sled feed seem to be a good solution. But I´ve seen two different styles. One has a flat bottom side, the other one is cut out in the middle - maybe 3/4 of an inch - so that the sled foot rests on two "end paws" only.
Which one is preferable, which one gives a better friction between floor and foot. Floor is OSB.
Du to the fact that my shop is in an old indoor pool there is no level floor. It inclines towards the former outlet. Therefore I´m in need of an opportunity to level the workbench without instability.
Any suggestions?
