Further to my previous post of some months ago, my on-going search for a "K" size belts has proved more difficult than I had imagined.
To recap, K-belts are common in the small drill presses which are ubiquitous in most tool stores. Not so the belt replacements. The crossection is 5/16" width and 1/4" (or 7/32") depth with the usual angle of 38 degrees.
The nearest I found is this belt by Gates:
The question then is: Is this belt likely to perform satisfactorily in a sheave designed for a 38 degree belt?
