Not posted any updates for a week or so because I've been going backwards - but that's OK. Gave up with the Melamine wheels and switched to MDF which is featured in this post. Also spent time setting up a sewing machine motor but not enough grunt, then tried a grass trimmer motor, power OK but revs far to high...so for now powering the bandsaw with a Bosch drill. Another thing...I think the skateboard bearings are really to small even for 8”/20cm wheels, might have to visit Schunk in Scoresby.
Bolted both wheels onto the shaft to trim them to same size and minimize radial run out, then put a 5° crown on each one.
You can see the crown here, need to visit a auto tyre place to get some used inner tubes so I can make tyres for the wheels.
The electric drill will be fine until I fine a suitable motor.
After cutting the wheels on the jigsaw table it’s over to the sander. To ensure concentric sanding my setup is to use two boards. The bottom board just provides a larger work area, the top one pivots. I position the wheel on the top board to overlap the edge and then tack the wheel centre to the top board. The top board is clamped in the bottom right corner so the wheel can be pushed against the sanding disc with the left hand and slowly turned with the right.
Also made a jig for the router table to cut smaller wheels and V-pulley stuff.
More to come…
