A few months ago I bought a motorized wire stripper. It has saved me many hours work. But it does have its off days and sometimes needs micro adjusting. Mine is the CO-Z model, about $150 on ebay. There are others that look exactly the same.
Does anyone have this model? Have you done anything to get better results?
In my first pic the allen head screw loosens up at times. If I tighten it too much I can not adjust the cutting wheel. The screw is about 1/8" wide but the slot in the big adjusting screw is maybe 3/16" so if I loosen the allen screw there is a lot of up/down play. I feed a wire and as soon as it hits the cutting wheel it pops up about 1-16". Also the cutting head has left/right play of maybe 5 thousands inch. This does not affect the cutting but it vibrates and makes too much noise. So I took off the safety cover and put C clamp.
On my last pic it shows the feed wheel. Most of the wire I strip (12ga or so) fits in the bottom V area. In all machines that is smooth. I took my Dremel machine and and put little scuffs all around. I just did this and I think I get better feeding traction.
Have you done anything to get better results?
Any one with same problems?
I know this is Chinese made (what isn't) but it is very will designed and very sturdy. Just a couple of quirks.
Has anyone tried to get parts? I see cutting wheel but that is it.
