Shopsmith Forums

hi there
I am hoping someone can help with a very basic question..I tried out the drill press and then went to put the1 1/4 " arbor back on to do some ripping - it won't go back on without forcing (I could get it on with the help of a mallet. However when I switch on it starts up and then the motor cuts out. What am I doing wrong? thanks for any help

For starters 'beating it on with a mallet'!:eek:

Are you aligning the set screw with the flat on the shaft?

Can you EASILY turn the spindle shaft?

Hi there ...thank you for replyig! There were no beatings, and no-one was hurt lol...I "tapped" it. Yes, I did have it lined up. The spindle seems to turn ok

Now, you seem to have two problems. First, the saw arbor doesn't seat properly on the drive shaft and secondly, there may be a power or motor problem.

Gotta deal with one at a time.

Put the Shopsmith into the horizontal mode (saw mode).

Take the arbor completely off and set it aside.

Inspect the power cord and measure line voltage if you have the means. I would hope you measure something on the order of 112 vac.

Look at the speed dial and tell us where it is set. I hope it is at low speed. DO NOT change the speed dial, at this time, without the machine being turned on.

Plug the Mark V in (I assume a Mark V) and turn it on.

It should turn on and you should be able to run the speed up and down through the range. Run it to low speed, turn it off and report your results.

We can go from there.

Did it run normally while you were in the vertical mode (drill press)?

......Checked the power cord - all good

.......The dial turns smoothly going up to fast...returning it to slow there was "resistance"...meaning it turns, but not as easliy as giong up

thanks

What you describe then seems to me to be normal. It is easier to move from low speed to high than it is to move from high speed to low. This is a characteristic of how the variable speed function is implemented.

I gotta go slow here though because I'm a little confused. I think in your original report you said that the motor cuts out shortly after you turn it on.

If that is true, now we need to test it fully assembled and ready to cut wood.

Put the arbor and blade back on and move the table into proper position as a table saw and turn her on. It should function exactly the same as it did without the arbor and blade.

Now for your other symptom. You were having trouble getting the arbor on and off the drive shaft. If that is still a problem, back the set screw all the way out and then slide the arbor on and off the shaft. There should be virtually no resistance felt while doing that. If there is some resistance, inspect the shaft for burrs and the arbor for any sort of contamination. Even an accumulation of saw dust in the arbor can cause what you are describing.

We'll be waiting to hear how this works out.

Be safe - remember you got that saw blade exposed.

.......The dial turns smoothly going up to fast...returning it to slow there was "resistance"...meaning it turns, but not as easliy as giong up



This is a good thing, it's ok to turn the dial fast going up, but you should always turn it slower when going down in speed.

Have you lubricated the machine? Maybe the extra weight of the saw blade is too much for it if it hasn't been lubed in a while. Just a thought trying to think what logically could cause this if it worked ok as a drill press.

The way the speed changer works you will feel more resistance going down in speed than going up. This is because when raising speed you are opening the speed changer pulley and basically the belt is going down hill.
When slowing the speed you are closing the pulley and making the belt climb the hill. in other words this is normal.

check the output shaft for any burrs. if there are any present file or sand them smooth.

Insure the set screw is backed out sufficiently. On more than one occasion I have found the set screw in a bit to far for the arbor to slip on.

mount the saw blade and test it again.

I just thought. If you are on an extension cord try running without it. Sometimes power loss through the cord can cause start up issues. If that is the case you will need a heavier extension cord. I use an appliance extension if I need one.

aaahhh - all is good....exactly as you suggested = cleaned the arbor and shaft and everything went great....thanks to all for quick and brilliant responses to damsel indistress...ina nswer to the cleaning and maintenance - I doubt this poor machine has ever had any maintenance...as soon as i get the manual I shall be right on it. thanks again
