I posted a similar question back on May 18 in this forum and got some good tips, but I'm still having trouble. I purchased the TandyPro Deluxe Leather Splitter a few months ago. My problem is, when I pull belt straps through to skive 7" at the buckle end, I am not getting a flat cut. It is cutting too deep in the middle of the blank, see photos. The light area on the end of my blank in the photo is cut too deep, I cut a cross section of the waste piece and am holding it in my hand in the photo, you can see how bad it is cutting. These are the steps I am taking to do my split/skive:
First, I sharpened the blade a LOT from how it came in the box, and kept the edge very flat.
I set the roller at the depth I want at both ends and tighten the two lock nuts
I start my cut while pressing back on the lever, cutting slowly for about 1/4" to 1/2" until the blade gets to depth
I stop and tighten down the roller with the large nob
Then I use a short piece of 2x4 to hold down the bar and the blank behind the roller, so the blank follows the curve of the roller from behind and slightly below
Then I pull the blank through slowly.
And it screws up the cut.
What am I doing wrong? Previously, and before I started holding down the bar and belt with a piece of 2x4, I'd split through the blank entirely and ruin belts.
I'd appreciate any tips or comments to correct this problem, thx!
