Internal Tube Sander

<< < (4/4)

RichardShute:
As commented a couple of times above, but I'll repeat it for emphasis, use something like paraffin or diesel or even white spirit in copious quantities. If you use 'oil' you will end up with a black paste and a clogged hone. If you were to use the drill press rather than the lathe to drive the hone, you could stand the tube on end with the bottom in a pot/tin/bucket of whatever you choose. That way, each time the hone goes down to the bottom of the bore, it will splash new fluid all round. Not quite as good as a pumped flow, but a lot better than an occasional squirt from a bottle.

You can use the above with wet & dry as well, I regularly do so for minor lapping jos.

By the way, did anyone say use lots of fluid?.......

Hi Richard

Im glad you mentioned that 'Black Paste', thats what I was talking about in my previous post.

My lathe is a 3-1 so i can use the mill and put the cylinder in a bucket, just need to work out how to keep it still.
