telescoping legs slide down too easily

[James Jacoby]

Sounds as if the tubing used in the legs was slightly undersized, thus creating the "bad batch" of legs. The manufacturer probably got the tube from Sri Lanka or Borneo. I have stainless steel kitchen appliances that are covered in rust spots. Ya just can't tell where materials come from these days. I bought some 90 degree pipe elbows that weren't 90 degrees at all. They came from India.

Hi John. If my tubes were slightly undersized, it really shouldn't matter, because the clutch lining, (a short tube with a gap in the side, and chamfered ends), won't close around the tube enough to close the slot in the side. I think a defect in the clutch lining material, may be the culprit. -Jake-

Could be Jake. But if the slot is closing up all the way, and not grabbing the tube??? Don't know how you could test for that either. You could use a micrometer and measure the OD of your tubing, and see how it compares to others. But now we're just talkin' dirty!

I have taken the slider, and the clutch lining out, separately, placed the lining tube over the slider and manually squeezed the lining, to see if the slot would close. (didn't even come close), but I opened up the slot with a hacksaw blade, effectively doubling the slot width, and it still slipped down, even though I had tightened the collar with all my strength! !If it was just, the tube, being undersized, Wouldn't it still grab, if the lining had enough slot width, and was squeezed tightly enough?-Jake-
