I have just learned on my other post that the knife jig of the tormek can only be precise when holding up to 3mm thick blades. Is this correct? My knives are mostly 4.8 mm ( 3/16 ) thick.  Do I always have to turn the stop of the knife jig to make the correct angle every time I turn over the knife.  Any help is greatly appreciated :-)

I have a tormek T7 that I bought 2 years ago. I used this machine to sharpen long and thin kitchen knives. So far I find the results very good. Recently I started to get in the knife making hobby. For my first initial offering I made two models. A small knife with a 3 inch  Wharncliffe blade and a survival knife with a 5 inch drop point blade.  This two knives are made in D2 steel and has a 3/16 inch thickness. The angle I choose is 30-35 degrees since this two are both sporting knives. 

Now, one problem that I have noticed is at this angle the knife has a high risk of throwing back at the operator. It has happened so many times already that some times it will put a damage on the stone.  When this happen, I fix the wheel with a truing tool.  Is there a way to fix this problem? Am I push the blade to hard on the wheel?
