Hey. I’m stuck. Trying to build this thing and I need a handle that spins for one end of it. I’ll use a steel rod epoxied in the other end with a cordless drill to power it. I recall someone here had already solved this but I can’t find the post. I bought the rolling pin at Target for anyone interested.
Depends on the intended purpose…is it hand held or bench mounted ?..If its high revving , you’ll need perfectly aligned bearings both ends , inside of the drive , with matched housings. Discuss it with a good wood-turner…there’s also off the shelf inflatable dolly sander attachments with easily changeable sleeves with different grits available .
I watched the vid Gadgetuk and (all humour aside) , a dolly sander would work well. It is an inflatable cylinder with rubber inner-tube that can be deflated to low pressure or pumped up to be as hard as wood . The abraisive sleeves are quick and easy to change , and any grit can be used …also inexpensive and off-the shelf…interesting !
3/4 plywood cut end plugs to fit inside of pvc…used a hole saw to cut end plug, epoxied them in with the all thread in place. The pilot hole from the hole saw will align perfectly in center. So all you need to do is get the proper hole sawcut out that fits in the innerdia of the PVC pipe. easy.
I got the bearings from a industrial supply place…they had literally Millions of different bearings…all .25 to $1.00 each, I got one that fit around the all thread size. The all thread runs all the way into the handle…The handle has bearing in it. The handle is 1/2 PVC. I just pushed the proper bearings into the 1/2 PVC and epoxied into place. The PVC cap hides the nut that locks the all thread…the cap keeps your hand from getting chewed up by the spinning all thread.
There probably more but my pea brain cant remember.
