Shopsmith Forums

I am not sure what the soapbox post was about.

I want to thank you guys that actual offered good advice. Thanks to Dusty; he took the time to measure his runout.

I agree. My updated spindle measurement result was .001".

After about 20 attempts with two different size drill rods, I am still around .010" at 1" below the chuck. This makes me suspect that it is the drill chuck.

I retested my spindle runout and it is around .001"; which is excellent for 64 yr old shopsmith with original bearings(right?).
After cleaning the inside of the chuck and retesting; I am still receiving around .010" runout (measuring drill rod 1" out from the chuck).

So does that mean that my chuck ...

Your results seem perfectly fine to me. I would expect to see those numbers.

I going to retest mine using a thinner drill rod to see if it makes a difference. I used a 3/8" rod in my first test, which is the same rod that I used ito test my floor mounted drill press.

Using a dial indicator, The spindle reading was done at the end of the spindle .002~.003".
The first chuck measurement was done on the end of the chuck body (I realize that this is not ideal) it was at .005".
The drill rod measurement was done at 1" below the chuck (.010"~ .012").

I agree that the runout is only going to increase the further out that you measure.

However From what I have read <.003" is within factory spec for the spindle. That is why I am asking if anyone has measured Thier chuck runout. These machines came with middle to lower end Jacob's chucks.

I've found an older user Manual for the jigsaw on the web; just search for it.

The manual calls for 10wt oil; such as sewing machine oil. I found the oil at Walmart in the sewing section.

I like my saw. The blade changes are a little harder than on a newer scroll saw.

I am wondering how much runout is common with the drill chucks? My mark v chuck is practically new, so I was suprised to measure the same amount of run out testing both chucks.

Has anyone else tested their chucks?

I recently picked up a 10E in decent shape. I have be spending this week cleaning it up and getting it ready for use. While I was at it; I decided to check the spindle runout. I was very happy to see that it is at <.003". Which is remarkable for a 64 yr old piece if equipment.

Next I decided to ...
