Help with my new(to me) mark v

[13013]

Hi all, I'm new to shopsmiths, as well as this forum. Earlier this week I bought two shopsmiths, one is a greenie frame with a '92 head stock, the second is an entirely '92 machine, the head stock says mark v but it has all the 510 accessories. This second machine I could use some help with. When I got it there was some minor rust I removed, and I oiled the head stock per the instructions in the manual that came with it. It ran and dialed through the speeds fine, though it seemed a little loud(I have never heard a shopsmith run so nothing to compare.) anyway, after cleaning it up I cut off a 2x4 on the table saw. It worked but looked a little rough. I looked at the speed controller and realized there was an arrow that I assume is where I should line up the speed to, which would indicate that I had cut too slow. I increased the speed and started another cut, but the saw stopped as soon as it hit the wood. I could still hear the motor spinning, but none of the shafts moved. Inside, I see that the longer belt which connects to the motor is intact but just loose, not contacting the pulleys. Can anybody tell me what happened and what I did wrong, and how I can fix it? Sorry for the book, and thanks in advance,
Regards,
Robert.

Most likely the machine needed a little maintenance. It's very likely the pulley sheaves needed to be lubricated and didn't slide properly as you changed speeds. You will need to lubricate the sheaves, reset the belt and do a high speed adjustment. Possibly re-tension. All of this is manageable/fixable. I think you will find most if not all of your answers here: http://www.shopsmith.com/ss_forum/maint ... t7092.html

Hi,thanks for the reply. Ok, so I went through that entire thread again, am I missing something? As stated in my original post I had done all the maintenance from the manual, including oiling the sheaves, unless I am completely misunderstanding that section of the manual (I put 3 in 1 in two places described, in the holes, prior to running, post cleaning out sawdust)
I may have missed a link on resetting the belt, I'll look through it again, but I didn't see that. Thanks.

Oiling is needed but that does not mean things are moving as they should. On used machines one never knows when it was done last and how much setting time has passed. If thing are gummed up oil alone will not necessarily fix it.

Sounds like it time to get a feel for the sheaves and how easy or sticky they are. They may need a bit more then oil to get them sliding right again.

You should also look for belt wear, once a belt is worn out it will go too "deep" and muck things up and will need to be replaced.

That little bearing on the end of the shaft needs oil too, lots of oil it turns out. Like wise the pork chop needs cleaning and lubrication.

Every 10 hours of operation you need to re do the oiling, if you turn out to be a heavy user this could mean once a month where as others might find once or twice a year is enough.

One never knows the condition of a used machine. If it was well treated and cared for it will stay that way for a long time. If it wasn't taken care of then there can and will be more efforts needed when you first get started.

I suggest a critical look at the motor pulley. The floating sheave is likely gummed up.

You may need to take the pulley apart to degunk it.

Thanks for the suggestions and information, I hope to find some time this afternoon to take a closer look inside and see what needs to be done. I'll let you all know what I find.

Ok, so I removed the table saw and took the cover off to try and figure this out. I decided to try re oiling it first because there was a third oil point mentioned above that I missed. I also don't think I applied enough to either of the other two points. So I fired up the machine and all the drive shafts are moving again. I slowly dialed it through all the speeds twice before shutting it off, and I noticed the "high speed shaft for jointer only" is really warm. The others are fine. Is this normal? I'm afraid to attach a tool to it if the bearing is bad. Also, is it safe to assume that if everything is running without a load that it will with a load?
Thanks, I'm sorry if these are dumb questions, I just don't want to mess it up and while I'm learning more every day, I'm just not very mechanically inclined.

The idler shaft will tend to get hot. (as well as the quill shaft).

With the belt cover off, observe the floating sheave as the speed is varied. It should be responsive to speed control changes with minimal delay/hunting.

If the floating sheave operates properly, try the saw again.


BTW do not be stingy with the oil.

The sheave movement looked good, so I put the saw back on and tried again, and it works! It is a bit smoother now too. Thanks for all the help everyone!

Great news! So, who says you are not mechanically inclined?
