Does anyone have a Lortone LU-6? I just got one but it needs a lot of work but luckily it was free. The biggest problem is the arbor has been cut so now it is just a saw. I need to track down a new arbor or have one machined. If anyone has one or the owners manual please let me know. I need to get some pictures so I know how the thing was suppose to be prior to modification.

Lortone is pretty good about having parts lists and exploded diagrams on there website in PDF format:

http://www.lortone.com/pdf/LU6X_130_PartList.pdf

of course, the manual for the current model may not exactly match older units. I found drive motor shaft size and other detals had changed between my ancient LS12 and their current diagrams, but it was a lot bettter than nothin.

I do not know if Lortone sells the arbor as a part. But I did see in the Covington catalog that the have a wide range of arbor shafts, and also take custom shaft orders. So, that might be an option besides local machine shops.

Good luck

I email Lortone and they are going to check and see if they have an arbor in their old stock. They said that prior to 1978 the LU-6 had several variations so I need to measure the unit to determine which arbor I need. They were not able to help on a manual and the current model is substantially different as for what parts are used. It seems like a pretty basic machine so hopefully I can get it running without to many mistakes. I just cannot understand what would make someone cut the arbor in the first place.

Was it cut or did it break?

I guess it could of broke and then was cut flush. The amount of force it would take to break an arbor seems unlikely to happen though normal use but you never know after 38 years of use.

Your probably correct in that it was cut.  I doubt if it broke someone would then cut it off.

Have you made any progress?

If you are having trouble finding the shaft let me know,  I probably can make you another one stronger than the original.  It shouldn't be all that bad. thinking13

Thanks for the offer but Lortone was able to find a shaft in old stock along with all the various parts that go on it. The shaft is only $12 which I bet is less money then having one machined. The only thing that they do not have is the top cover over the wheels. So I will have to try to figure out a way to fabricate one.

I emailed Lortone about getting a manual for my used machine and they were kind enough to send me a PDF manual via e-mail at no cost.

Yes they have been very helpful with all my questions. I just placed my order this morning for some of the parts and am in the process of tracking down the others. Once I am done it should be very close to being a new machine. yippie

One thing I've learned from refurbishing old units is the original units had a 1" SC 100 grit wheel and a 2.5" expanding drum.  Almost impossible to slide belts on and off without running into the pan edge.  I would recommend if you have to buy wheels, go with a 100 1.5" diamond wheel and 1.5" expando drum.  Belts will cost less also.
