Use of the 14" wheel

I use a 14" on my Bader was scared to death of it at first but now I could'nt get by with out it. I use it to rough grind out the "junk" on the bevels and rough grind the flats.
 
I use a 14" wheel on a Dozier, but only for hollow grinding. I'm not sure why you would want to grind a blade vertically on a wheel. It seems to me like it would be difficult to maintain the flats on the blade without making ripples.
 
My homemade grinder has a wheel that is 15.25" and I sometimes grind blades vertically for rough clean up or hitting a high spot that I see while flat grinding on the platen.
 
I use a 14" wheel for flat grinding - I hollow grind the blade first and then flat it on the platen. There's not much to grind off after it's ground on 14.

The guys who do grind vertically tend to follow up by flattening on the disc grinder. My limited experience is that grinding vertically get scale of more quickly for some reason.
 
Same as the rest.....Clean it up on the 14" vertically ( pretty flat), then the 9" dis ( nice and flat), final either on the flat platen and/or by hand ( as flat as I want it).

That is how and why I do it. The belts seem to last a little longer because the heat does not build up on the wheel, like it does on the platen thus transfering the heat to the belt. It tends to fall away with the "grindings". I dont use a disk though, I put them on the platen but only as long as it takes to true everything up which seems to be very quick.
 
Don't have a 14" but have a dedicated machine setup with a 16"......love it but I don't do much flat ground blades but when I do I use the flat platen to rough in and work the rest on a 9" and 4" flat disk grinder.

There would be a lot less surface area involved in the grinding which would make the belt cut quicker I guess. I never have thought about it before but it would make sense it you followed it with a trip to the flat platen or disc grinder to be sure it was flat. We just do it all on a flat platen with sharp belts and a glass face on the platen.
