The DoAll 16" LHF Bandsaw, Part 6:
Now that the gearbox was in place, it was time to install the bandwheel. The old arrangement had used a rough
red phenolic washer that somebody had added as a spacer. Well, besides being a poor spacer, the new bearing
was a different thickness (the previous rebuilder had used an incorrect 'cartridge' bearing) so I needed a different
spacer anyway. AND, there's every chance I'll need to do some tweaking to the spacing as I adjust the band
tracking, so I wanted a measure of adjustability. So first I made a sort of primary spacer, that filled much of
the void around the bearing, in an effort to help keep dust and swarf from building up in there.
That fits in like so.
Over that goes a wide washer- if I have to adjust the wheel spacing, I can use thicker or thinner washers,
I won't have to make the entire spacer again.
And of course the bandwheel itself, which is now in exactly the same position it was when I got the saw.
the lever and shaft used to switch the gearbox from high range to low range, was a sloppy fit to the chassis.
This was because the shaft went through a rubber grommet, that after 67 years, had finally dried out and
cracked. I could have just replaced it with a new rubber grommet, but I had a better idea- I made this
Delrin plug that is a 'snap fit' to the body, and a snug fit to the shaft.
And, while not strictly necessary, I discovered I had a 5/8" locking collar in my drawer o' junk (hey, packrat)
which was a prefect fit. The original shifter eccentric and locking collar hold the shaft in place at the right,
while the new Delrin bushing and new collar hold it in place at the left.
And yes, I did, in fact, remember to put oil in the gearbox. Also note the, er, note-
"New Bearings, Nov. 2015". I wish more people left little notes like this...
Aaaand takin' it for a quick test run! Smooth, quiet... I'm happy so far.
