The ones I chopped last night were all over 30mm, had eight to chop and all were finished in much less than an hour, and I'm a slow worker, need my tea don't ch know. Once in the mortice, depending on the wood, I can remove a chip 3 to 4mm X 25 to 30mm with out working hard. A couple or three taps, a push against the bevel to remove the chip and on to the next chop. Doesn't take long and best of all no set up other than marking and putting the mortise appliance in the vise.
Anyway, cut to the chase.....I chopped the mortises for the second of the three side tables last night. I'll dig out whatever is going to be the rails after work tonight and unless MsOK has other plans for me I should have a table by Monday....Anyone want to make a bet.
