Hello All:

Did a search and didn't come up with the proper steps to grinding in a distal taper. Any help would be greatly appreciated. Thanks for the help.

before you start the bevels, try grinding vertically on your platen and push hard with a push stick at the tip. I forge my taper in, but on some knives, especially big ones, it needs some help on the grinder. Another way to get it done would be to do whatever you would do to taper a tang. Lots of tutorials on that, including one in the old Bob Loveless book.
 
Thanks Joe.....I'll give 'er a try. Was kinda what I thought, but wanted some feedback before I screwed something up. Oh well, if I screw it up, I'll chalk it up to learning experience and try again. And Bruce Bump would be proud of me, 'cause I'd throw something in the screwup box. HaHa.

I put on a large contact wheel,and draw the blade upward and out.The point of contact is the place where the belts comes off the wheel and goes back to the drive wheel (The lower slack belt).The blade is pointed toward the drive wheel.A few well applied pulls on each side,using a 50 grit blaze belt, will taper a blade prior to grinding.Like jmd61, I forge in the bevels on most all non-stainless.But, there is no shame to grinding it in either.After the basic taper is roughed in,switch to the flat platen and clean it up prior to grinding the bevels.I do the tang the same time as the distal. ( On smaller stainless blades,I do the whole taper on the 6X48 sander)
 
If it is a forged blade the tapers can be forged in. If its a bar stock blade the taper can be ground in on the flat platen.

side note: if the bevels are ground all the way to the spine, a distal taper will form automatically.

BTW Bob Jensen is my ABS apprentice and makes some very fine knives. I would put my own name on most of them. Im looking forward to see him post some pictures of his work.
