Hive Mind Question 2

[Bryan Milham]

Folks,

I bought out the contents of a retiring turners workshop, there are a couple of things I'm not sure about.

This is the second I have no idea about them, there are two of them, one has a removable centre, there are bearings for them to rotate on but otherwise I cannot see what they might be for,

Any suggestions welcome.

Bryan this could be totally wrong. Years ago when hand held routers (for cutting wood) first came on the scene there was a plate that bolted underneath a bench with a hole in. The router attached to a spindle that passed through this plate and was bolted to the bench. The top of the spindle had a thread that took a threaded cutter, usually a dovetail cutter, used for trenching out stair strings. As I said it could be totally wrong but it looks similar.

John,

I Can see where you are coming from, but the workshop came from a medical man who turned as a hobby. So not sure he'd have something for creating staircases, but unless someone else knows better it's a better idea than any I have.

What I will say is the wider flange on the discs fits between the bead bars of the lathe (Poolewood Euro 1500).

Could these be the base for the sphere cutting jig?

[Bryan Milham]

Paul,

I did consider that but if you look at the toolpost of the sp[here jig, at the top you can see the flat areas for a spanner, just then same as on the Sorby Toolpost system (but it's not Sorby, it has a different thread).

And the bush where the arm stands out from the post does allow it to rotate, so I don't think they would be needed for that.

Hi
They look to be stub axles of some kind. What size thread are they ?do they conform to any
Lathe spindle?
To be honest they look they have come off a trailer the grease and dirt on them rather than any thing connected to wood turning?
Sorry I could not be more helpful.
PS are there any grooves around the end of the plain dias of the shafts

[Bryan Milham]

Redtail, I'll check and get back to you.

I'm thinking they might be the two bearing plates for a turntable, does one fit on top of the other?
