So I am grabbing up the parts to upgrade my mini-lathe. Ordered new bearings. Ordering the extended bed (+6") in the next week or so. One thing that I want to do is install tapered gibs. I have seen it in bogs thread here and saw it in cfellows thread over at HMEM. What I am looking for is some good in depth detail on a how to. Anyone done this? Anyone know where one may find what I looking for?
Help

This will be my main machine until I can get the cash for that 10x22. Then it will become a CNC turning center :borg:

Hi Eric,
I think Bogs was improving on Rick Kruger's tapered gibs. Drawings for them can be found here: http://warhammer.mcc.virginia.edu/ty/7x10/vault/Lathes/7x10-7x12-Projects/TaperedSaddleGibs/
As an aside, my 7x12 (a machine made by Weiss in China, and with different architecture from from the Sieg C3 and Real Bull mini-lathes) has no gibs at all on the saddle, though they are shown in the manual. The side plates under the saddle seem to have been fitted to the bed. This hasn't given any problems with saddle rock over the last 4 or 5 years, so I'm not going to fix it unless a problem does arise. I could always put spacer strips on top of the side plates to create a gap, and add conventional gibs which are slightly thinner than the spacers.

I have had no trouble with my original factory bodge, over the last 6yrs. (Chester Conquest).

I intend, eventually, to make accurately stepped cross section strips, to bolt straight on in place of all the adjustable bits.
Or, am I missing something? :scratch:

Yup. That was what got me going on this. I just would like a little more info on it.
Thanks for the links... I may have what I need now!

I suppose you could cut down on parts by milling a slope along the relevant surface of the retaining plates, and use a single correspondingly sloped gib on each side.
If you buggered up the side plates (which I'm sure wouldn't happen ::) , replacements aren't expensive: http://littlemachineshop.com/products/product_view.php?ProductID=1388&category=5 , though they would be easy enough to make from scratch.
