Did the carving with a Modulus Arms jig on loan from Mr Skeezer of (clap clap clapclap) Texas.
Marv soothed nerves and read the instructions in the proper order.
Being extra careful, it took us about three hours.
When you do this yourself, remember the shop vacc!
Update:
You either need a drill press with at least 2.626" travel or a means to measure your depth when you reset the table. My press has 2" despite being advertised as 2.375". I drilled 1.750" then moved up the table 1.750" then did the remaining 0.876. The drill stop is my friend!
The huge problem is the price on a benchtop model with more spindle travel costs a lot more. Almost three times as much.
