Question: ( JWL1236-49 )
Does this include the crank handle that is shown on the exploded diagram attached to this part?
I bought a used blue jet wood lathe. it starting making a noise when shifting into the higher speeds, and now it will not speed up when I shift it to go faster.
You may want to check your spindle and motor pulleys, to make sure they are separating and closing when changing speeds. Also check inside the head stock where the JWL1236-21 speed selector goes into the head stock. Make sure all the parts inside it look okay.
I took off the cover and can see the spindle pulley will squeeze together for lower speeds, but dose not exspand to higher speeds, so it only works at mid to lower speeds. i can see the shifting lever bracket move to the right to make room for the spindle pulley to exspand
or should the shifting lever bracket be pulling the spindle pulley with it for higher speeds ?
Question: Jet 12-36 Lathe
Some follow up info. Both electricians tried many different methods, however the motor was drawing between 60.5 Amps to 72 amps, but only for 8 to 15 seconds before a breaker would trip. Basic wiring appears to be in tact and not disturbed. The only wires being hooked up are the power cord.
Looking to buy a bed extension because I thought this lathe would take a piece that long. I turn baseball bats and need a few inches extension. Would that be part JWL1236-52w?
Unfortunately as for as far as I know Jet does not offer an extension for the the JWL1236. The part number JWL1236-52 is for the tool rest base and tool rest, for outboard turning.
Question: Part No. JWL 1236-02
Where can I get a spur center for a JWL 1236? It is listed on this site as unavailable/obsolete. Does this mean I don't need it, or can I use a generic one or one for a different manufacturer? What does one do if you need a spur center?
Reply: Part No. JWL 1236-02
All you need to know is the Morse taper size, probably a #2 on a lathe that size. You can get one at any woodworking retailer that sells lathe equipment. Or here's a link removed
Hope that helps.Merry Christmas.
Question: Describe Jwl 1236-46
In absence of a picture, is this a heavy walled, highly polished tube, @4.5" long, @1" OD, into which tail stock fits on one end, and lead screw fit into other end? If not what is number of described part? Thanks
