Link belt too wide

[BruceW]

I bought some link belt to run my belt head driven lathe.
I have removed 5 links so far but stile can’t get enough friction in the v pulleys.
The spindle head bogs down when cutting and slips with little force.
I have about the max tension on the belt and believe this is not the problem.
I belief the belt is a bit wide or my vees are a bit small.
It sits high up in the pulley.

I’ve been thinking, if I can get the belt into the pulley more and create more friction it should work properly.

Do you think that say taking a grinder and sand off a little of the side of the belt when it is running to narrow the belt some and make it seat deeper in the pulleys will work?
Better way of thinning the belt a wee bit?
These measure b belt but a bit weird. The old belt ended up riding way down in the vees a lot more before giving up the ghost, but still had more friction drive than this does.

Suggestions / fixes?

Thanks
Bruce

Link belts come in different widths, maybe you bought one a size too large? In the US they sell it in 3/8", 1/2" and 5/8" (roughly 10mm, 13mm and 16mm).

Direction matters too
If the belt is not in the correct orientation, it will not transmit power effectively

The next smallest belt would have been too thin and ride on the bottom of the pulley’s/gear head.
The direction of rotation is correct.
The last belt was a gates and took a beating till it died.
I change the bearings in the pulley’s as they were shot.
I didn’t want to disassemble the head bearings and shaft again to put a new belt on and thought these would work well.
I have 3/4 hp but the belts loose fiction with anything but light cuts.
I guess I will try and see if sanding the edge thinner will help grip and friction.
The belt hasn’t stretched anymore for a while so I think the links are well seated now.
It is quiet and vibration free thou.
If the tabs of the belt are facing inwards and backwards from rotation, then I have it the right way round.
