tension knob moving

[Woodrush]

I have an excelsior 21 and was wondering if anyone has found a solution to stop the rear tension knob from moving. I was told to tighten the nut underneath the knob, but it's so tight, I can't move it. If I don't keep an eye on it, it will move an inch by the time I'm done a couple of projects

There are a few postings on this topic. I had a similar issue with my EX-16. My solution may have not been elegant but it was fast and solved the problem. I used a wide rubber band and looped it around the threaded shaft and attached it to the 2 screws that are mounted on the side of the unit. It works.

What happens is the threads in the mounting block and maybe the threads on the shaft get worn and become a bit sloppy.. and it just continually gets worse.. You have several options to fix the problem but most people just use a rubber band as has been mentioned. 

You can buy a new mounting block and shaft if you feel like spending some money and also are comfortable with taking it apart to change out the parts.. Not awefully expensive parts but non the less you're buying a part that in time will do the same thing again..

I went a cheaper route and took mine apart and used blue ( make sure to use blue so you can still turn / adjust it ) lock-tite on the threads. It's been good for several years now and going strong.. If you don't have lock-tite another option is just wrap some pipe thread tape on the threads.. but that might not last as long as the lock-tite. 

I'm a person that likes to tinker and take things apart anyway and so it was the method of repair I chose.. I can understand the much easier rubber band method that others use too. 

 

Scroll down a ways on this posting and you'll see pictures of the set up and what I did to take this apart and use the lock-tite.. Rubber band is much easier but if you're handy and had the saw for some time.. might not be a bad idea to take it apart and grease up the bearings etc. anyway..

I also used blue locktite with great success
