Damn Bubba cut to the chase.....As I've posted before I've round heels when it comes to ways of sharpening. Basically I've decided there is no one correct way to do the job just some ways work better with one type of tool and iron than than others. Lately I've been trying CBN grinding wheels on the tools I grind. They, CBN wheels, grind supper fast and stay cool but I'm not sure if it isn't too much of a good thing. Bottom line while driving the Princess around the PNW I thought of some changes to make to the grinding station. Once home and back to work, projects this small are about all that can be done for another month or so.
All that is a long way around to posting a photo of the changes I made to the shop's grinding station a couple of days ago. I removed the Tormek rest, mounted both the 80 and the 120 CBN wheels and installed a couple of adjustable tool rests. Does it work any better? Maybe....I'm not 100% convinced the CBN wheels are better and may replace the 80 grit wheel with a Norton.
Why the switch from the tormek to what you have now. (Lee Valley tool supports?) I read that the CBN wheels lose their ability to grind straight. Derek Cohen did a write up on these wheels.
ReplyDeleteCBN wheel can be pricy, I hate the idea that they don't stay straight long...??
ReplyDeleteLook like a Veritas grinder support on the left and a Wolverine jig on the right.
Both made in the land of Maple syrup and Ski-Doo , heh! :-)

Ralph,
ReplyDeleteThe Tormek set up was a little too fiddly, I'm a lazy sod don'tchknow. In time I might have figured it all out but but I'm not a big fan of grinders and use 'em as little as I can. Went with simple.
The CBN wheel is really fast, almost too fast. It also runs very cool but, there's that damn but, even the 120 grit leaves a very deep scratch pattern. I'll play some more with it because some of it may be lack of skill using a wheel but I expect the grinder will end up with at least one Norton wheel.

Bob,
ReplyDeleteCan I be an honorary Canadian? I instruct in Bombardier aircraft and like Cross Canadian Ragweed's music (OK so they aren't from Canada instead they are a Red Dirt group from Oklahoma but I like the name anyway).

LOL
ReplyDeleteOK Ken, I'll hereby by the power invested in me by Labatt Blue ( a fine Canadian beverage used in moderation) I grant you the title of honorary Canadian :-)
Which A/C do you work on, Dash turboprops or the Regional Jets?
Bob, who flew the Dash umpteen times and was briefly involved with the 604 in an EW role, fun days :-)

ReplyDeleteBob,
ReplyDeleteI instruct in the Challenger 604 and have instructed in LearJets. It's a pretty cush job, a chance to tell almost 50 years of "there I waz" stories and get paid to do it.
