For KMG grinder owners

[Natlek]

Well , tension spring for tightening belt works .Gas spring works even better and ratchet is best , right ? What do you think about this simple modification on this kind of grinder ?Should work with steel spring and with gas spring ? So simple to do and all you need to do it is to tight that bolt after you put belt on ? Grinder should work same as you have best ratchet tension on the world ? I cant find clear picture on net of KMG from that side so I draw this .I think it is clear what I mean ? I can t see any reason why this should not work ? Only one more bolt to tight before you start grinding ? You can use that handle for bolt , I forgot how you call it .............. ?

Interesting idea - A question here. I was under the impression that grinders with a fixed tension (rachet, etc) didn't use the "tilting" tracking wheel for tracking adjustment because the act of tilting the wheel would increase or decrease belt tension. I have changed my KMG clone to a horizontal tracking adjustment as used by the new Reeder grinders (shown here:

) and really like it. A fairly easy mod to make and think that work work nicely with a "locked" type tension adjustment.

Ken , on KMG grinder you adjust tracking before you tight that lock bolt on modification I suggest .Put belt on ,tighten belt as always ,run grinder ,adjust tracking and last tight that lock bolt, simple as that . If you have no play in tracking/tension arm it will work perfectly .Even if it need little correction I don t see problem with little adjusting after locking arm....main advantage of that kind of locked tension is better tracking ,no belt walking on side , more efficient grinding , no belt slip on drive wheel . . . .
About that grinder on that video ......I don t see any reason to complicate simple thing like this .If grinder was build precise I don t see why you would need that ?

The biggest purpose of the tracking in the grinder video is the tracking wheel always stays level, not tilted in any direction.

Put belt on ,tighten belt as always ,run grinder ,adjust tracking and last tight that lock bolt, simple as tha

You're right, that would work nicely for sure.

I understand that , but noting wrong if tracking wheel is tilt for one or two degree ....On this grinder when I adjust tracking , tracking wheel is 99% aligned with all other wheel .One plate ,small distance between wheel and it is easy to get everything in line .......In 100% precise build grinder and 100 % properly jointed belts tracking would not be necessary .....

looks like it should work. i would put the tightening bolt as far away from the fulcrum point (pivot) as possible to increase the holding leverage, and to decrease how hard you need to tighten it down to make it not move.

Yes , it should work . All the benefits that come from ratchet mechanism on belt grinder come from the fact that ratchet mechanism does not allow tension/tracking arm to be pushed down and lose tension on belt when we put pressure on belt . . . . And this is even better then ratchet mechanism .With ratchet you depend on size of teeth how much +- you can adjust tension , at least it would be more complicated .For slack belt grinding this way you can adjust tension as much as you like ....
