Dad has run the 2-1/4HP one for years. There is a knob to lock the height. Your satisfaction with the cut when not locking the height will be directly proportional to your requirement ;-) The only other bothersome design of the router is the power switch. Let me see if I can get this straight; it has to be in the off position in order to raise and lock the collet for bit changes, you have to slide a spring loaded cover over and turn it on manually. This is only if you raise the collet up to lock and change bits, not during any other function. I would bypass this switch and use an external one but, dad has just made do. This is the only negative I can even remotely think of about the router. The supplied dust shroud has let dad hook a small vac directly to the router and he has never enclosed his table!?! Not a lift by any means but, bad deal at all.
