This may be the wrong area but I have an old Black & Decker model 9400 Type 1 drill press that I have been trying to find a belt for without success.
I bought the tool new some 30(?) years ago and unfortunately the manual now resides at some previous location and all of the internet sites I can find list the belt as obsolete/not available.
The drill press works perfectly otherwise and I see no reason to get rid of it when v-belts are pretty much standard.
By all the measurement instructions I can find it seems a 26 inch belt is indicated, but that is too short. Does anyone have info on an old classic the specifies the belt dimensions?
If you bought a 26" belt and still have the packaging take it back and get a longer one. You can buy V-Belts by dimension rather than model number. The Napa store I use the guy will take an old belt and put it on a tool that measures it.
There is more than just the length, the width is important too. If you have your old belt, measure it to make sure. I will cut the belt to get the right length measurement instead of trying to get an accurate measure around it.
I just recently ordered several belts from http://www.vbeltsupply.com/. Their prices were great, better than Amazon Prime, and I got better belts. I was shocked at the shipping, ordered Monday, arrived Wednesday.
