Locking knob lost
Hi - I'm a newbie as you will surely guess from my questions...
I inherited some tools including a router from my Dad, but no manual. It is a Craftsman 315.174771 fixed base model. According to the parts list on the Sears site there should be a locking knob which I believe locks the bit depth after adjustment. Sears no longer carries this part.
When I tried to use the router I found that the bit (and the housing) move vetically about 1/8 to 1/4 inch quite freely unless I apply some downward pressure as I operate it.
So my questions are:
1. Is the bit supposed to move up and down relative to the base when you press down/lift up the router?
2. Is the locking knob essential?
3. If so, can I simply use a nut, bolt and perhaps a spacer through the flanges in place of the knob?
Thanks for any advice...
