Faceplate sanding disc.

(1/3) > >>

DickDastardly40:
Take one 7" disc of plywood

Drill 8 holes to the pitch of the slots on your faceplate not quite through

Adjust for length 8 suitable wood screws and find some suitable spacers in this case nuts and washers

Screw disc to face plate

Skim edge and face lightly to true up

Stick on some abrasive paper with spray mount and trim edge


Yet to make, a work surface.

John Hill:
They are going to be right onto you Dick for allowing abarasives near your lathe!

I am only mildly paranoid on the subject but I do believe in taking precautions and I have been warned NOT to lay a cloth over the ways to protect them, the danger is that the cloth could be picked up in the machinery and maybe drag a hand in with it,  ouch!  I suppose newspaper would be OK and you could hold it in place with magnets.  Mr Sparey (?) author of the amateur lathe users Bible (c 195x ?) says to use damp rags.

BTW, does anyone know if a lathe coolant system is likely to recirculate abrasive particles?

Al,

Nice post.

It wasn't long ago that metalworking machines were sold as dual fuel. They could be used with both wood and metal, with the ones designed to handle metal as well, having ball raced bearings to take the extra speed.

I personally have no issue about using abrasives on a lathe, as long as the bed is protected as well as possible. I use a toolpost grinder, which I am sure will bang off a lot more abrasive than a sanding disc. Some people go way over the top and won't even allow a bit of emery near a lathe, quoting that it will remove x amount of material from the lathe bed at each operation. All I can say is that they are talking thru their a**e. Those sorts of people need to get into the real world, and stop polishing and start using their machinery. Without having abrasives near a lathe, most manual production shops would soon go out of business.
It is all to do with common sense, if you don't have any of that, you shouldn't be using machinery anyway.


With regards to your question John.

Lathe coolant systems usually work with an impeller type centrifugal pump, and will quite merrily pump anything that is put into it. I used to work with one that pumped hot liquid solder.

To prevent contaminants being pumped about, usually you have a couple of good quality fine mesh filters in the line from the lathe drip tray, and the last stage is to send the liquid to trickle over a barrier plate that allows solids to settle out before reaching the pump sump. That is why you should always have a regular regime where the filters and settlement tank are cleaned out. Your pump should be like mine, and it has all the necessary requirements.

Good project Al:- thats a real useful bit of kit :thumbup:

Putting a magnet in the suds tank will pick up the iron bits  :headbang:

John Hill:
Thanks John for the practical opinion on the question of abrasives though I am rather upset that you think it is not necessary to polish my lathe!  Over the last few weeks I have managed to get all the showroom rust off and got a nice shine on all bare steel using a Scotch Brite pad and WD40/CRC.
