Rebuild Craftsman 101 Carriage
- Thread starter capt.ron
- Start date
That is a rather curt description of your problem and task at hand.
I can safely presume you are talking about a Craftsman lathe, hence the reference to "101".
On to the carriage gears... If I go out on a limb and presume this is a 12" swing lathe (not the smaller 6" with which I have no experiance) then the following gears are "sweged" to their shafts:
Carriage Traverse gear 9-102-125 (Qty 2)
Cross-feed gears 9-102-24 (Qty 2)
There are all installed on the square ended shafts and then the end of the shaft is dimpled with a center punch very close to the edge such that the dimple upsets the metal and causes it to expand against the inside square hole in the gear.
I have successfully removed these gears from their shafts by supporting the gear on top of a stub of pipe (or open bench vise jaws) and driven the shaft out with a pin punch and ball-peen hammer. If the gear is worn, broken, or teeth stripped you don't care about any damage to the gear. I have done this several times without any damage to the gear.
To install a replacement gear on the same shaft file any burrs left from the previous center punch marks so a replacement can can be fitted - don't file too much, just enough top remove the burr. Once the gear is seated then lay it down on a anvil or other hard steel surface with the shaft vertical and using a center punch and hammer set several ding marks in the end of the shaft close to the square edges so that the gear is held fast.

Where I said "...gears are "sweged..." to their shafts" the correct term I think is '"staked".

A heavier carriage for your 12x36? What model? No matter really, because there isn't one. The carriage for the Commercial version is built for the 1/2" thick ways and will not fit on a lathe with 3/8" thick ways without modifications. The carriage traverse gear mechanism will be 1/8" too low to engage the rack properly. You would need to figure out a way to shim under the carriage but on top of the ways or maybe mill 1/8" off the top of the apron. I don't know how this will impact alignment of the lead screw.

Sources for Atlas/Craftsman lathe parts:
- Clausing - They still have some parts available. You know they are genuine.
- Searspartsdirect.com - Anything they have Clausing will have for less
- Ebay - Prices are all over the grid. Often more than not Clausing will have parts for less. Often parts Clausing no longer has are available on Ebay.
- Craigslist.org - Usually complete or nearly complete lathes. Hopefully one will have what you need and you can sell off the rest on Ebay. Good luck!
- mymachineshop.net - A fellow named Joel (Ebay Joel7052) makes some parts such as traverse gear case, but I would call Clausing to get a price first.
- flywheelmachinetools.com - has a small selection including brass cross-slide nuts, tool post rockers, manuals, and sometimes has other loose used parts.

Ron,
Clausing sells parts based on cost at time of acquisition. Not on prices in some 1930's or 1940's catalog. For example, in 1941, a Steady Rest for the 618 or 101.07301 sold for $3.75. Average used price today is around $150. The list price in 2006 was $102. Lord knows what it would be today.

i bought parts from clausing before when i stripped the gears in the quick change gear box scared of ebay parts want to take it apart today if i get time im going to replace the brass huts and the striped gears while i got it apart iis there any thing else that should be replaced i am going to sell the lathe when i get it fixed this time want it right model number 101.07403
Hard to advise what to replace next. If you are going to sell it I would replace only what is broken. Things that may be loose and wobbly like the carriage handwheel can be fixed by installing or replacing a bushing in the apron, that's a cheap and easy fix. But buyers seem to want mostly bargains, i.e. low purchase price. So it is far easier to sell if all is functional though not necessarily perfect then it is to refurbish and paint to like-new condition in the hops if getting a higher price.
