Singer 211g151

I recently got a singer 211g151 and have been trying to sew leather holsters on it. I’m new to leather work. I been having trouble with the thread bunching up around the bobbin and/ or cutting the thread. Is there a way to get this machine to sew leather or am I wasting my time messing with it? I am using the braided wax thread and sewing 5-6 oz leather. Needle goes through the leather with ease it just doesn’t tighten on the bottom side resulting in the bunching up and cutting thee thread. Any help is appreciated

First: you should not run waxed thread through this type of machine because it will clog the eye of the needle. The only wet agent that won't clog the needle and throw off the tensions is liquid silicon in a wax pot on top (which your machine probably doesn't have). Your machine can be used with bonded nylon, bonded polyester, cotton or polycore sewing thread. Avoid braided thread. Use standard left twist sewing machine thread. Do not use hand sewing thread.

The maximum thread size is #138 (Tkt 20) for bonded nylon or polyester threads, using a #23 leather point needle for leather, or round point needle for webbing, vinyl, or cloth. You can compare thread sizes on this thread and needle size chart. If you want to sew with cloth thread, the biggest size would be heavy jeans thread, which comes in size 105, or heavy button thread. Just make sure your thread does not exceed .0163 inches (.414mm).

FYI: Size 138 bonded nylon thread has 22 pounds breaking strength. If you decide to sew a holster with #138 thread make sure you sew parallel lines of stitches an eighth of an inch apart. I sew most holsters with #277 bonded nylon thread, which is way beyond what your machine can handle.
