This instructable will show you how to make custom wooden knobs for a fraction of the cost of ugly, plastic store-bought ones. I recently had a need for a few knobs for an adjustable miter fence for my table saw. Rather than buy the plastic ones, I thought I'd make my own - always a better choice!
For each knob, you will need:
- A scrap of wood - preferably a hardwood like maple, oak,
mahogany, cherry, hickory, etc.
- A threaded insert
- A screw that fits the threaded insert (cut the head off
- Sanding/shaping tools like a belt sander, wood rasps,
- A drill press helps, but is not necessary
Step 1: Find a Blank & Lay Out the Shape
The first step is to identify the blank of wood you will be using. Things to take into consideration are aesthetic quality, grain direction, species, or any blemishes you want to either include or avoid. For a really hard hardwood like maple, the grain direction will not be critical - assuming you won't be really reefing on the knob with all your might. For this Instructable, I am using maple.
Step 2: Drill a Hole For The Threaded Insert
It is easier to install the threaded insert while the blank has square and parallel edges, so next we will drill a hole that will receive the threaded insert. With a hardwood, it is important to size the hole properly for the insert. You can probably look it up, but the hardware store where I got mine has the drill size listed in the bin with the inserts. Carefully lay out the location of the hole and clamp the blank into a drill press vise. Set the depth of the hole based on the dimension of the threaded insert. Just turn on the machine and drill away.
