Belt tension question

[Chris'knives]

I am putting the finishing touches on my NWG and was wondering how to tell when you have got to much tension on the belt. I used a slightly different type of tension spring and am wondering if it is to much. The spring I used is called a stop shock spring for trapping. It is kinda like a door spring on steroids.
Any help is greatly appreciated.

Thanks

It really depends on how far out you place the spring and how long your arm is.

Generally speaking, on my two grinders (Burr King and KMG) I apply more tension until the belts track correctly and usually not any more. So start off with little tension and try adjusting tracking, the more tension, the more responsive the tracking adjustment will be. If you get the tension too tight, the bearings won't last as long and your platen (assuming you have the belt adjusted where it drags on the platen continuously) will heat up much faster.

Hope this helps

You should be able to run your tension pretty high without any problems.

I know makers that have air cylinders that are used for tension and the criteria for too tight is when the belt splice breaks.

I personally run my KMG as tight as I can get it. I have complete confidence in the way it is built and the bearing life at this tension.

tighten that junk ALL the way up

when I built my NWG I used a caliper spring from an old Drum brake
