    Default Performax/Jet 10- 20 Design Problem

    Pete Sent me the drum support arm from his Jet 10-20 drum sander..He wanted me to see if I could fix it for him..The thread on the lifting screw had stripped causing the sander height adjustment to fail..It wasn't the thread on the steel leadscrew that had stripped but the female thread in the extruded aluminium arm ..I thought of a few ways of fixing it but couldn't decide which to go for..so this morning I went into the shed to take some measurments from off my Jet 10-20, I wound down the adjusting screw to the bottom setting, then started to wind it back up again but nothing happened the handle turned the screw shaft turned...then I realised what had happened THE HOWLETT CURSE had come to visit me..Mine had stripped as well...A quick search around the Web proved that this is a common fault with the 10-20 and I found about six owners in 5 minutes of searching who had the same problem...."Now I have two machines to fix"....I think that the problem is that the extruded aluminium material is not thick enough at 15mm or strong enough or suitable to lift the weight of the roller assembly and motor combined...In this thread I'll attempt to show you how I went about the fix.....

    EDIT Due to Photobucket for removing all my pics and asking for a ransome to restore them ..I have made a video of the repair and it can be seen here https://www.youtube.com/watch?v=RsmnY8dCODA

    If you can believe that moving images and sound, can fly through empty space across the universe and be seen and heard on a box in your living room ?.. then you can believe in anything.

    I noticed that on Petes spindle that there was no sign of lubrication, so I thought at first that was what caused it...but mine is covered in grease from the first day I received it, and it still stripped just the same ...anyway when i've done my mod it should fix it for good. (Fingers crossed)

    I wonder if this is a problem with the 16/32 as well. My screw has developed quite a bit of slop in it. Perhaps a sign of impending failure? Then again, I've never thought of lubricating it!

    Remember that the whole weight of the motor and roller assembly hang from that single point ...just the threads that is...sometimes when they go, is during sanding operation and the spinning drum and motor just drop onto the conveyor belt/workpiece and gouge out a drum size hollow bit..."Chuck" the relacement part on the 16-32 dosn't look as expensive as the 10-20 it can be found here on page C http://www.ereplacementparts.com/jet...661_32864.html ..item 37 $64..90

    Good Link! I've looked all over for replacement parts for the Performax without any luck. For me it's the "spiders" that keep wearing out. That's a valuable site to bookmark. Thank you Ken.

    EDIT: I've just ordered the part (as well as some spare spiders) expecting impending disaster. Why would they use aluminum for this critical part?

    Wow, I just got mine a week ago, & have sanded exactly one fingerboard. I didn't find any mention of this problem in researching the purchase. Guess I'd better spend more time researching next time. I'll be eagerly following this thread.
