I would love to get my hands on an original drawing with the dimensions and specs of them.
Gents,
After a couple of weeks of fruitless searching, and finding only used and questionable
bronze bearings for my Heavy 10, and since SB/Grizzly is out of them,
I am going to have to make my own.
I plan to start with some 600 series bronze sleeve bearings, and then bore them in a
support sleeve in the 4-jaw. Then I will have to hone them on the Sunnen machine to
final dimension. Then on a long expanding collett, turn the OD to size.
Finally I will have to split the bearing (done in the chuck sleeve from the first step)
and then mill the dovetail for the key. Oil holes will be installed with an end mill.
Concentricity, ID dimension, and parallelism are the issues here.
Any suggestions? Experience? The bearings are cylindrical, not cam ground like a piston ring.
If there is any interest, i will photo document the project and the results.
Facing some interesting work,
Phil L
Was just about to post some pics of it.StepSide does your headstock look like this? It's the cast iron bearing version.
Supposedly it's very durable from what I've read on other forumsView attachment 234458
Those should be serviceable, pull the spindle and polish , maybe fine scotchbright
How many shims were in there ?
While your at it replacing the spindle oil wicks would be a good idea.
What problem is the spindle giving you.
I agree, I was wondering where the shims where as well, if any. Yup, polish that spindle up and get it set to spec with a lift test. Probably outlast us all!Those should be serviceable, pull the spindle and polish , maybe fine scotchbright
