Converting to Belt
Just curious why so many knifemakers convert wheeled surface grinders to accept a belt? I have 4 surface grinders and wouldn't hesitate converting one if there is an advantage to doing so.

hmmm, no use converting, nope, no need in that!
in fact just send me one yellow freight Seriously, cooler running, new belt+true every time, convenient grit change, more takeoff per pass. With 4 machines, I'd definitely change one and see for yourself. Call Bader, they can fix you up. __________________ Jason G Howell ABS Journeyman Smith howellknives@yahoo.com http://www.howellbladesmith.com |

I agree with Jason, you don't need 4, you only need 2, so I'll gladly give one a home in my shop too!
Jason, is there any concern with flex in the wheel, or is that just splitting hairs? What durometer do you recommend? Thanks! -Darren __________________ Gas Forges, Refractory, & Knifemaking Supplies Refractory.EllisCustomKnifeworks.com Visit the Forge Gallery - forge building resource pages ForgeGallery.EllisCustomKnifeworks.com |

I don't think there should be a concern for flex. Serrated will let you hog off plenty per pass. Besides, I finish on the platen anyway.
Not sure on the duro, check with Bader, the can steer you right. Maybe even Rob Frink? __________________ Jason G Howell ABS Journeyman Smith howellknives@yahoo.com http://www.howellbladesmith.com |

Thanks everyone for the info and the links. Maybe I will convert one.
Sorry Darren and Jason I'm not ready to get rid of any of them yet. But nice try!! __________________ Shawn Scott |

The durometer on most knifegrinding contact wheels is too soft for this application. The rubber is going to cup slightly at the edge of the steel. You will not get as precision a surface as with stone wheels, even with a harder rubber, but except for critical applications it won't matter. It's a lot faster than stones, too, especially in applications like flattening damascus billets. The first one I'd ever heard of was a chap from Michigan back in the 80's who'd made one that was engineered so well he could put near a mirror finish on balisong blade flats, his specialty. Wish I could remember his name, but that was more than 2 minutes ago I last remembered it. Can anyone help me with the name? He sorta hung with Chuck Stewart and the Gottages in the 80's.
Many of the folks building their own conversion have happily purchased wheels from Bertie Rietveld in South Africa. He sells a higher-durometer wheel: http://www.batavia.co.za/ Last edited by fitzo; 07-29-2003 at 02:12 PM. |

Bertie wheels are out off this world,I bought a 10 inch contact wheel from him and is it the best tracking wheel I own.

I was all excited waiting for a conversion kit to come out. I almost fell off my chair when I saw the price. Geez, You could buy a whole grizzly for that, and have a 150.00 dollar buffer motor left over.

The diameter never changes on belt systems like the rocks do when they wear.
Rubber wheels hog it off, and metal flat wheels can dress off the billets quite nicely. You will only true the wheel ONE time(not every time). |
