Skiving Machine Inquiry

[tribo korokan]

"The grinding wheel should touch the entire angle of the original grind of the bell knife, yours seems to be messed up" I need to move the bell knife forward to make the entire angle be grind. The grinder is only hitting the tip of the bell knife. Thanks you all for all the great suggestions.

HI Tribo,

your feed wheel should feed the material true. You need to go true the adjustment to find the zero position on the feed wheel (parallel to the knife) then work on you knife edge. You should not have to run grind stone very long, but if your edge is wrong and has burr`s. Then you must use the time it takes to make i good again.

And Like Ferg says (that I wrote too) use the dresser tool on your grind stone; it should sharpen the entire edge.

Well, the paper adjustment method is quit simple and is to make your feed wheel parallel to the knife. Its not a thickness adjustment! you must bring you feed wheel out again to the proper (desired) distance from the knife. Like I wrote in my post.

I adjust the feed wheel distance from thin to thick leather, but leave as is for most upholstery weight of leather. Then I only have do the adjustment on the foot height.

And of course; I too have to do test runs on the same material before doing the actual skiving job.

Tribo,

is your machine a constant speed knife or a variable speed one? Mine has a constant speed knife and variable peed feed wheel of course. If you have the first option, perhaps it will skive better on a higher speed. I thinks its possible to change the knife speed relative to the feed wheel, change the belt to another pulley (inside the machine). I do not know because thats never been an issue on my machine.

Good luck
