Greetings everyone,
We recently acquired a new DCS-S4 Consew bell skiver (It's possible it was refurbished. We purchased it from Consew itself). It worked great for the first month, but for the last few months has been behaving badly and I can't find a way to fix it. I'm newish to skiver repair, though fairly experienced with industrial sewing machines.
Here is what happens: after being skived off, the scrap somehow comes back up around the roller stone. The scrap seems to stick to it. This is with several types of leather, from buttery soft kid to crisp several-mm-thick laminated stuff used for a leather jacket. (forgive my lack of knowledge about leather types, it's not my area of expertise!)
I thought maybe the leather scrap deflector was bad in some way, so I moved it around, and even removed it to make sure the leather was not worn down all the way. I can't see anything obviously wrong. It is positioned firmly and fully against the stone.
The "waste feeder metals" (Consew's part names are bizarre...it's the same part as 1.50 1105 in the DCS-S3 parts book*) is present. I don't know how it is SUPPOSED to be set, but It looks like it's in the right place to "scoop" the leather scraps out of the bell knife. It doesn't adequately clear the bell, I should note. I have to go in fairly often with tweezers to pull scraps out.
I then thought maybe the stone had gotten sticky with leather residue so I cleaned it with a soft wire brush. No change.
So I'm out of ideas. Anyone have suggestions?? The image attached is from when I made the mistake of walking away from the student skiving, and this happened.
Thanks for ANY suggestions. I'll take them all into consideration.
