|Making Wheels without a
Not having a lathe, I devised the following method on my router
table to make the required wheels for my John Smith Senior 20.
Using a piece of MDF board, I marked the radius centres of the various wheels
from the leading edge and drilled holes the size of the shaft on which they
will run. Cut roughly shaped wheels and mount on the board with a piece
of shaft set in the appropriate radius hole.
Move the board forward so that the edge is just touching the cutter edge
(I find that a cutter with a profile-following bearing is ideal for this)
and clamp board in position. Move the blank slowly in an anti clockwise
direction against the cutting action of the bit and you will have a smooth
wheel. Use smooth slow actions and dont try to cut too much at
one go and you will get perfect results.
This would work equally well on a bandsaw with a narrow blade or also on
a disc sander.
To put a groove in the edge of the wheel, clamp the board vertically to the
fence and with the correct sized core cutter, it is a simple matter.
