I loved the shop-made threaded knobs from Woodsmith video tips so much that I had to make some for myself. I decided to make them as part of a set of hold-down clamps, but I did make a small change. As you can see in the photos above and below, I created a riser under the knob to give my fingers more room when using it.
These knobs follow a similar style to those in issue 252, but with a little extra wiggle room.
After making the hold-down, I made a riser from a 1" maple dowel. I drilled a hole to accept the carriage bolt and made a recess in the threaded knob for a T-nut. The carriage bolt feeds up through the riser and into the bolt. To ensure the riser wouldn’t slip around, I glued it securely to the knob.
