Greetings fellow sawdust makers. I am a hobbyist woodworker looking to expand the tool arsenal. I need a biscuit joiner. I am making some cabinets, out of melamine, and the only way to join gables with floors or tops, without seeing screws, is by using biscuits. I borrowed my dads old canwood. Not too good. Depth gauge tightens on one side only and not parallel with the blade. I looked at the Porter Cable(MODEL 557). Looks good but no lock once depth is set for the fence. Does this matter. Norm doesnt seem to mind, I think he uses Porter Cable. The DeWalt looks ok too. (MODEL DW682K) Any advice or preferences or tips would be greatly appreciated.
