Buffing machine

[johnny5]

Wanted to convert my bench grinder into a buffer , the man in screwfix put me off saying that it can be done but is dangerous as the bench grinder has guards that make access difficult and limited and not meant for buffing.
He told me to buy a sealey purpose built bench buffer.
I have looked and the cheapest is £97
Anyone know of a cheaper bench buffing machine ?

 

[Neil Lawton]

Just take the guards off, they are usually just screwed on.
My buffer is just a double ended motor with pigtail mandrels attached.
Axminster used to sell left and right adaptors like this proops tapered spindle left hand 1/2" 12.5mm polisher pigtail tapered nose New | eBay, but I'm not sure they have them now.

 

[George Watkins]

keep in mind that you get best results on wood and or acrylic at under 1500rpm

Like George says, grinders can make very aggressive buffers.
Better to buff on the lathe in my opinion, I used to use the Charnwood solely for that purpose and it always worked well.
A bit of threaded stud held in a Jacobs chuck with the tailstock up the other end held three different grades of wheel easily.

I got one of these and use it on me lathe and they work perfectly Heavy Duty Polishing Kit for Plastic, Fibreglass & Bakelite - Polishing Mops & Adaptors - Grinding & Polishing - Workshop Equipment | Axminster Tools & Machinery

I used one of these the other day Woody and it melted the acrylic , did i have the lathe running too fast ?

I would say so or you were pressing it to hard or to long in one place run it at about 1300 rpm gentle touch and keep it on the move

I just put my mops on the lathe with threaded studding like Brian suggests, works a treat.

I use that system for wood and bowls Bill

Have you looked at the Beal Buffing System Johnny. Attaches to the lathe and very good results.

 

[Jim]

I just use a buffer on a motor controlled with an inverter for the speed .. See Here ..

 

[johnny5]

Thanks everyone for your comments,
just bought two buffing wheels , one wide stitched and one wide loose leaf 6 x 2 buffing wheels & two drill mounted pigtails and wax for £50 off evilbay.
I agree the polishers for sale are 2750 rpm and using the VS on my lathe would be better & safer option using the jacobs chuck.
thanks

My pen buffer a laboratory stirrer vertical in another life 240v variable speed control on the end with on off switch 50 mm buff I only lose it every now and again the blank ie.always get it back. I have others, msade an adapter in brass works now for many years.

Glad you got sorted Johnny

Buffing Station

I made this and I no longer wet sand anything. If interested, I would be happy to furnish the details. I am not saying this is best or anything like that; it happens to work well for me.

Cheers,

Tony

Does anybody have any experience of the buffing attachment for the ProEdge?

 

[wm460]

I use a beall buff system.

I would be interested Tony I can get studding and nuts locally I think I would have to send off to the polish shop to get the mops and polish bars.

Re inverter usually means something that converts 12 v DC to 240v AC usual use is in caravans and I used to use them with old valve transmitters I think what Jim has is a variac which usually convert one voltage AC to an other voltage AC either more or less than the original voltage with a turn of a knob in this use to speed up or slow down the motor.

An invester that Jim speaks about is actually converting the Hz (frequency) of the electrical supply and not the voltage.

Usually we run at 50Hz in the Uk t 240 volts. The one that Jim is using will usually change the frequency from 0 to 60 Hz

But the voltage will stay the same. They are a better way of controlling the speed of motors.

You can over speed a motor giving it 60Hz but if you reduce the Hz too far then you will need to supply some cooling for the motor as it may overheat.

Hope that explains ,

Up date, remember as a guide that 2 pole single phase motor runs at 3000 RPM, 4 pole motor runs at 1500. (1450 to be exact)
