Thread: Slideway and machine oils

It is to save the scale, it's just a longer bolt with a plastic cap on it, and it has a nut that holds the way wiper on.

Perhaps the comment about "lifting" it is a bit misleading. It's not so much lifting it off the ways as taking pressure off the front of it. I doubt it's high enough to allow any more gunk to slide under, and I always make an effort to clean the ways before sliding it around too much anyway.

Just what works for me.

Pete has it right...the action is just to relieve the bulldozer effect on the leading edge of the tailstock. I have read that some larger lathes had air injection into the tailstock to allow it to float along the ways, a piece of innovation that I am doing my best to ignore while in the rebuilding phase

I'd never heard of it until you mentioned it, but the air sounds like a great idea Greg. The layer escaping would help blow any chips out of the way on the ways too. Goodness knows there's plenty of hot air to spare around my workshop, it's just a matter of harnessing it for such things!!!!

Pete

Thanks fellas. The tailstock wipers look like the go. I'll put it on The List.

Thanks everyone on the wiper advice.
Just finished fitting Tailstock wipers on my Hercus 260 lathe.
Purchased the die cut felt & metal holders from Mal at AMH.
With a bit of modification made one set to suit the flat way.
They work well.

I take it you are still working your way through the new Coolpix instruction book Bruce.

I have just been searching for Paula's saddle oiler modification details in PM's South Bend forum and found this thread about installing oil cups in the tailstock. Seems like a idea with some merit. Easy enough to acheive with a two piece tailstock. - Installing ball oilers for bedway lubrication

I'm still looking for Paula's thread.

Saddle oilers would be a worthwhile mod, but in their absence I just regularly flood each way wiper with oil. The oil runs down through the felt and onto the ways.

very soon

Found one of Paula's posts. It seems that an oil cup is more beneficial than a nipple. - Carriage way oilers

BT

From what I can read Bob the problem seems to be that there is no space for a reserve of oil to go. Paula was hoping to use the space at the top of the V. I'm wondering whether the top of the V in the carriage needs to be machined out a little bit so that it can store some oil. If you think about the volume of one of those cups not much would need to be taken off. All you want is a void that oil can sit in and will allow the air to be displaced/ compressed.
The bottom of my tailstock has a cavity in it for that reason - the oiler feeds to the cavity and then the oil gravity feeds to the oil outlets on the base. The system works fine (until some idiot decides that shooting it full of grease is a better move).

In the Seattle scraping class they showed us a tool for releiving the corner of dovetails. It was just a length of hacksaw blade set into a wooden handle. See illustration.

Such a tool could easily provide enough relief in the apex of the vee.

Bob, if you are planning such a mod, I have a plethora of ball oilers.
