i have a weaver 8" splitter. this is my experince and i also have a question to others who use these types of rollar splitters.
i used this many times on about 8/9 leather down to about 5/6 with veg tan. if the width is below 2" about the cuts are smooth. meaning if you are cutting a 3' strap with 2" width to 5/6, it begings at 5/6 and ends at 5/6
now, im noticing on some PARTS of the hide, usually but not always the belly, and over about 3" width you will start with 5/6 and end with 2/3
i can not say for sure it is the softer parts because this happens with the firmer parts. I also ntice a lot that this happens more with the bigger widths over 3"
ive done so many and i can not figure it out for sure. some times i pull on the feeding ends upwards and might help and cranking faster might help too.
i think it comes down to the rollars as the bottom one is on springs and pushing the feeding leather into the top so the crank can push it into the blade. the problem is it is not always a consistant level
has anyone figured this out? is it the width, type, parts of leather?
