Yes your belt has stretched to much from age or it is the wrong size. You might be able to get a little more adjustment by raising the lathe. That might give you some time to use the lathe while you are getting the right belt. ply v belts don’t need a lot of tension when they are in good shape because each v is pulling down into the groove giving you a lot of surface tension for friction. When they wear they slowly get narrower and eventually just the tip of the v is making contact and you loose all that surface and you have to replace the belt.
