Polishing lathe in a cabinet


#1

Has anyone tried mounting a polishing lathe in a cabinet similar to a
bead/sand blasting cabinet? That’d solve several problems, hooked up
to a vacum it’d trap the dust (precious metals too), and when things
went flying they couldn’t go very far. Guess I’ll have to put
together a set of plans, what’d ya think?

Hi all,

I recently made a cabinet to hold my polishing motor. The original
machine was a grinder that I removed the original grinding wheels and
guards and attached a pair of tapered spindles to mount the polishing
wheels. I made the cabined out of 12mm outdoor grade plywood in the
form of an open fronted cabinet about 900mm high, 700 wide and 300
deep with a couple of hoods on the top to enclose the wheels with the
motor bolted to the top. The cabinet was assembled with construction
glue (e. g., Liquid Nails) using 20 mm square section cleats in the
corners tacked together with nails. Access to a small compressed air
nail gun makes this task much faster. Polyurethane glue would work
fine as well but I would not trust the PVA white woodworking glue for
this task. It is not a piece of fine furniture but it is strong.
Inside the cabinet I installed 40 mm PVC waste pipe coming up into
the bottom of the two hoods joined to a T piece in the centre. On the
front I installed a relay switch with a green start button and a
large red stop button connected to the power and with 2 power
outlets. I sat a vacuum cleaner in the bottom of the cabinet with its
hose inserted into the T section of the drain pipes.

I plugged both the motor and the vacuum cleaner to the power outlets
and left them both switched on so that they are both switched by the
relay.

So far the whole system seems to work well.

If anyone is interested I can send a photo.

All the best

I think that Rio Grande, Otto Frei, and others sell such a hood. Rob

How well It will work will depend on wether your going to use glove
ports with the thick vinyl gloves.

Difficult to hold small items id think.

All the polishing setups ive seen in big industrial goldsmiths never
use them.

always a proper hood around the mop/spindle with a good strong
vacsystem.

also a grating to stop whats got away from you from going up the
spout and through the vac fan!!.

I’m late to this thread, but thought I would chime in on where to
possibly get hoods & hose parts:

The local “Woodcraft” store carries vacuum hoses, attachments and
various shaped small sized plastic “hoods” all designed for
woodworking vacuum systems. They even had a collar that pivots around
when screwed on to the table. I used this to thread the vacuum hose
through a homemade bench so all I needed was one little hood type end
and I use it for all my “dirty work”

Hope this helps!
