Topic tags/keywords: question

I have a Delta 3-HP shaper. After a year without much use, I discovered that the spindle could not be raised or lowered with the side crank handle. It appears that there may be some light rust between the sliding surfaces that has locked it up tight. Just wondering if anyone has had this problem, or may have a suggestion.
Thanks very much!

I’d try some light penetrating oil, say PB Blaster or RustBuster and see if that helps. Also make sure that if there is a lock on the spindle height adj that it’s un-locked. I know, DUH but stranger things have happened. Otherwise you may have to remove the carraige and get it on the bench to see what’s up. Just remember, if it looks like it’s made from “cast metal”, don’t be too hard on it. That stuff breaks really easy and is a bitch to fix. Good luck.

I agree with Dbear, also check the owners/operators manual, it should cover this problem.

Thanks for the good suggestions. I did try the penetrating oil and double checked that the spindle lock is backed off. Before removing the carriage, I thought about lightly heating the out part of the assembly with a heat gun (probably not a torch!), and maybe tapping lightly with a small brass hammer. Any thoughts???

Give the penatrating old a day or so to work. Heating with heat gun before you use the oil will help it to get in all the cracks. Torch would be OK if you don’t heat to a color change, just get it warm not HOT. If it doesn’t break loose, pull the carriage and go from there.
The shaft should be chromed and the cariage plain steel so unless this was in a cave or under water I can’t think that the corrosion would be so bad as to fuse the parts together. Is the shaft bent? Just seems weird that it won’t move at all.

Update to Dbear on my Delta shaper problem:
Your suggestions gave me incentive to take a closer look. You were right that the parts were not corroded because the shop is fairly dry. While trying the heat and the tapping, I noticed that the raise/lower threaded shaft has a collar on the end of it, secured with a small set screw. The set screw was loose, letting the collar jam against the end stop of its travel. When I tightened the set screw, the shaft could turn freely again and everything works just fine.
That simple fix probably saved me a ton of work and money! Thanks again!

If you have the manual for the machine, I would suggest going through the initial set-up procedures again. Just to make sure everything is in the proper position and nothing binds. Glad it was something simple but I’d double check anyway.
