I have a Lurem shaper, which was used for making raised panel doors at a custom van conversion manufacturer. At some point, the key for the drive pulley fell out and partially ate the motor shaft keyway. Do any of you have suggestions for repairing the shaft? It’s just 1/4″ square key stock. I assume the shaft diameter is larger than absolutely necessary, so I am thinking that it could be turned down a bit and an adaptor made for the pulley. Otherwise, I would consider selling/trading it. It has a sliding table with hold-down clamp, fence and is on a stand with casters that flip up to make it stationary. The motor is mounted on a plate that has 2 levers which rotate to release it from the base of the machine, 220V with magnetic switch. I also have 3 sets of Freud raised panel cutters for this shaper.
If anyone here is interested in this machine or the cutters, you can contact me by e-mailing to:[email protected]
I also need a bandsaw, minimum 14″ that I could add a riser block for resawing. I would like to have 12″ of height, if possible.

I think that the shaft could be TIG welded, providing that it is welded in steps. These steps would give time for the weld to cool and not do damage to the wire on the armiture. The shaft may also be turned and remachine the key way to the proper depth, than bushing the pulley or purchase a new pulley. Grizzly I believe sells pulleys with under size bores for finishing to your need.

It's not a regular pulley for a V belt. The motor is bolted to a plate that has 2 levers which capture one pin each and clamp it to a plate with the pulley and it's bearings, which are pressed onto the pulley. The belt is flat and the pulley is crowned, so the belt is self centering. The motor is behind the spindle on the opposite side from the sliding table. I'm not sure why they designed it this way, but it seems like the key was supposed to be slightly tapered. If I knew someone who can weld everything well, I would take it to them. I got a quote from a machine shop of $180 to repair the end and it seems excessive. I understand setup charges, but I also took shop in HS, so I know that a competent machinist can set it up in minutes since the centers weren't machined off when they finished the shaft.
The motor is disassembled already, so the armature can't be overheated. I was thinking that the shaft end could be ground so it's true and round, machine a new keyway, install a two piece(upper and lower) sleeve that's the same size as the shaft end was before it was damaged. If the sleeve is welded on with a keyway machined into it, the welds would be strong enough for this application.
On the other hand, I talked to a friend about this and he said I should try JB Weld. It's worth a shot anyway.

What part of the country are you located? I might be interested in this machine, but the freight could get a little ugly..
Also, how about some pictures?

I'm in the Milwaukee, WI area. It's really not tremendously heavy since the table is aluminum and has an open base. This shaper was mainly used for making stiles and rails for the doors in conversion vans. It also has a sliding table with clamps for holding the stiles and rails in place. In addition, I have some cutter sets, if you're interested.
