dan,
If it was me I'd take it apart (carefully) and check for any burrs along the slide and rack gear. Best probably to use a fine india or arkansas stone to go over the edges. Check for any swarf in the gearing. If it sticks in the same place consistently, it might be burrs. Use a good magnifier.
Hope this helps,
Frank

Dan, to make it slide better your going to need oil, and lots of it. I recommend 80-120wt well used differential oil. The "milky" looking kind is best. Shake off the excess, and your ready to go.

Me, I'd watch out for that Joel guy. http://bbs.homeshopmachinist.net//wink.gif

PolskiFran's advice sounds reasonable to me, although it sounds to me as though it may just be dry. You might try some lightweight oil of your favorite brand http://bbs.homeshopmachinist.net//smile.gif and see if that helps before you go to the bother of disassembling. With something like this, it's probably impossible to precisely diagnose at a distance. You'll have to just wade in and figure it out. Remember, the first rule of intelligent tinkering is to save all the parts!

If anybody cares (probably not), my "favorite brand" is Birchwood Casey synthetic gun oil.

Craftsman precision stuff used to be pretty good (1960s, 1970s), but I have no idea what it is like these days.

Dan,take that caliper back to Sears and tell them it doesn't work right ! Craftsman tools are guarenteed for ever.(Says so in the fine print) I used to exchange tools from work,took a feeler gage that someone picked up off the highway,had been run over by many wheels!! The salesman said 'as long as it was just used and not abused',gave me another one. They still have vernier calipers.

Well, I'm not so sure about taking it back....

If you can actually get something equivalent now (you better believe they will exchange, not fix), it may be worse than what you have.

What you have can be fixed, the newer variety will very likely be a worse POS from the start, and unfixably so.

Can you tell I am not a Craftsman fan?
