Drill four 5/8-in.-dia. 1/2-in.-deep holes on the large disc?inside the traced circle?then use 5/8-in. dowel centers to transfer the hole locations to the underside of the small disc. Drill four 1/2-in.-deep holes on the underside of the small disc and a 1/2-in.-deep hole in the center of the top for the dowel handle. Glue in the dowels to join the discs, and glue in the handle. We drilled a wood ball for a handle knob, but a screw-on ceramic knob also provides a comfortable, attractive grip.
@cahudson42 I bored the holes in my sandwich top with a 3/4" power auger bit with the drill in a portable drill guide that kept it vertical and in a way a bit like a plunge router. The guide screw of the auger was dead easy to centre over the laid out grid points. The holes are dead straight and clean sided. The auger bit was new which probably helped. As stated I have three rows from an end vise running the length of the front as well as from the front vise and holes in the front apron to support long pieces as well.
The end vise will have both jaws made out of 1-1/2" thick oak. The front vise has its moving jaw made of 1-1/2" oak, but uses the edge of the bench as its stationary jaw. So while for the end vise, if we mount it lower, we can make both the jaws deeper to compensate, for the front vise we cannot, so we want it mounted as close to the edge of the bench as possible.
When this book showed up at my studio I was very sceptical. Yet another “book of everything”? But after spending only five minutes skimming through it, I learned about a couple of storage ideas my shop needed, some cool new jigs that would come in handy and a few tricks to make my time in the shop more enjoyable and productive. There will be hundreds of ideas in here you will have no interest in whatsoever, but that’s all right … there are over 650 ideas in total, so some are sure to tickle your fancy.
This table top is also made from the hardest wood out of any manufacturer we reviewed: oak. In fairness, this can be both a blessing and a curse. The oak wood is extremely durable and noted for its lack of a porous nature. This means the top can withstand plenty of abuse from tool and workpieces. Moreover, you will not have to worry about liquids like lacquers and stains from being absorbed into the top. That said, the hard oak can also do a number on tool sharpness, dulling them prematurely if they are not carefully handled.
