Mechanical help

[onebdzee (Premo)]

Here is the issue: I work with a industrial size sewing machine....There are set screws that hold the presser foot(the piece that feeds the material through the machine) in place....After using the machine for a little while the screws vibrate out....I have tried heavy duty Lock-tite so far and it didn't work....Is there something that will hold those screws in place?

J B Weld. If ya do use that, don't plan on taking the screws out anytime in the near future.

flat head washer then a lock washer with some red loctite should fix the issue. Otherwise maybe use a rubber washer then a flat head washer then a lock washer. This would allow them to handle the vibration. You have to figure out a wash to absorb the vibrations.

What color Loc-Tite?? how long did you let the Loc-Tite set/cure? Is there heat build up (friction maybe) on the shoe that may cause the Loc-Tite to release?

Neither red nor blue Loktite should loosen with that application. You may want to crimp the threads on the setscrew plus Loktite.

And if the loctite is white.. check the bottle, you maybe using Whiteout!!

Hopefully it will work.

I did a search on "sewing machines" yesterday, so ironic you brought this up today.

I just replaced a 60+ year old Singer with a new modern machine.

Of course, industrial machines are not so dispensable or cheap for that matter.

Yeah no kidding....I bought this one almost 2 years ago($3500) and I use it everyday with heavy weight material....Other than some of the smaller screws loosening up, it does great!

Still have my moms old Singer(60+ years old, too) that's holding up even better for the house ....figure I'll give it to my daughter
