I am considering constructing a hand wheel. I have no idea what kind of bearing to
use, however, as I don't know a pillow block from a thrust bearing. I know pillow
blocks have been used with success, but is there any type of bearing I should avoid?
What supports the weight of the shaft? Any direction would be more than welcome.
Thanks!

Hello Chris,
Sounds like you are headed in the right direction...I am no expert myself,
but I have been working on building a Leach Style Treadle Wheel and found
the best bearing for my application to be a "Bolt Flange Bearing" or "Block
Flange Bearing" rather than a "Pillow Block." The only significant
difference is in the way they are connected to the supporting structure of
your wheel. Look on the internet at these two different styles and you will
see what the difference is. One may be better for you than the other. As far
as supporting weight, they usually have at least one set screw, if not two.
If you need more support than that buy a good fitting "shaft collar" to hold
some of the weight.
Good Luck.
Chris

To best support a vertical load such as on the wheel head shaft for a
kickwheel a thrust bearing would be in order. I built one of these long
ago and the materials I used were as follows
6X6 steel plate, drilled for bolts in each corner for mounting.
Automotive wheel bearing (this was a tapered Timken roller bearing. -
very specific - must be tapered roller type.
Bearing race
Piece of leather - Circular or square to cover the steel plate.
I had a machine shop machine the steel plate to accept a press fit of
the bearing race.
I had the machine shop turn the end of the shaft so there was a
shouldder on one end that would sit on the inner bearing race. This was
the thrust point of the bearing and shaft. The load of the shaft was
transferred to the inner bearing race then to the tapered bearing whose
rollers were set at an angle, in turn transfering the load in to the plate.
The bearing race was pressed in to the plate. The shaft was set into the
hole in the inner race. The leather had a hole cut in the center to fit
the shaft. The bearing was greased and the leather slid down over the
shaft. the edges of the leather were fastened down with a sheetmetal
ring and screws, making a dust and dirt catcher to prevent gret from
wearing out the bearing.
The upper end of the shaft near the wheelhead was held in place with a
pillow bblock bearing mounted sideways.
The system worked really well. I built it out of some premium hardwood,
was very careful with the carpentry, counter sunk all screws, plugged
holes, applied fillers, sanded finely then stained and varnished the
thing. Someone came along and made me an offer I couldn't refuse. I sold
it for enough to buy my first brand new Brent CXC.!!!
