Bobbin case hanging up on Consew 225

[art]

Howdy from South Texas,

I am new to the forum.  I recently acquired a used Consew 225 in very good condition (or so it seems).  My problem is the bobbin housing and the bobbin seem to gall up.  A few drops of oil and the problem goes away for a few minutes.  Also, the thread regularly binds up in, around, and under my bobbin case.  It does this with #69, #92 and #138 thread (these are the only three I have tried).  After it binds up, I clean everything out with needle-nose pliers, a couple of drops of oil, and it works fine again for a few minutes.  Is this something I need to have a sewing machine shop look at?  I've done some internet research and haven't found anything to answer this question as of yet.  Hoping to draw on yall's experience.  Thanks, Art

Sounds like this machine is being improperly used.   Find a good book or info.  For basic sewing techniques or at least a guide for this consew 225, same as singer 111w155.

Greg, Thanks for the advise.Do you have a recommendation of any particular book? I do have the operators manual  however its not very helpfull. I am sewing 2 to 6 layers of sunbrela or cordura and webbing. I was told the consew 225 would work fine for this.  Any advise is helpfull.Thanks Art

My consew 226 did that a bit . But I learnt to keep tension on the threads as you start to sew - by gently pulling them.

I always do the first stitch manually , then continue on with power.

Same here. I've got the Singer 111-155. If I don't keep that top thread tight when I start sewing it'll bind up almost every time. I don't think theres any thing wrong, just the way the machine was made.
