new 2x72 grinder

That's cool.Is that a pattern you came up with yourself ? If so you should draw up a set of prints to sell,or cut them out and sell it as a kit.

God bless,Keith
 
The inspiration for this grinder came from Wayne Goddard, except I bought the idler wheel and contact wheel instead of scrounging for a skateboard wheel and a trolly cart wheel.

My Craftsman ran at 4400fpm and this one at 4500fpm - difference is this one doesn't slow down when you touch the steel to it:)
 
Nice job, any chance you saved the cutout plans? If so, I sure would be interested.

Bruce! Great design here, I have been wondering about trying to build a simular setup out of wood. You have done all the brain work for us. Really looks great!

Any chance you might have time to put some dimensions up on here when you are not playing with your new grinder? Would be greatly appreciated!!

Bruce that is a nice set up. Would you be able to share the dimensions? Looks like it would save someone alot of money on buying one. Thanks again for sharing. John
 
Very, Very cool!! Nice job. Maybe this will help more new guys get a 72" grinder.
 
this is great its exactly what i have been looking for. great job thanks for posting!
 
Being a wood worker I applaud your ingenuity and design, the fact that is functional and actually works makes you da-man----great job--I gather from the remarks and hints from the other post as well as my own interest that there is an interest and market for your unique invention in one way, shape, or form......Steve
 
Honestly guys you could get a Coote or Grizzly for near the same price (shipping one of those up here to Canada would have been pricey though).

Here is a breakdown of the costs in CAN $ including shipping & border taxes:

$202 idler wheel, 9" ceramic platen liner, 4ft of link belt, mandrel, & 2 three-step pulleys
$100 10" Grizzly contact wheel
$30 machine shop charge for putting a bushing in the contact wheel so it fit the mandrel shaft, and cutting a key-way slot into the madrel shaft
$80 plywood, Gorilla glue, wood screws, hinges, bolts & nuts, spring
$145 for the 1hp motor (and it was on sale $50 less than normal)

Total was $557

If you guys still want some dimensions, or tracing of parts - let me think about it for a bit and use the grinder some more. So far all I've done is grind on the flat platen & slack belt (yet to try hollow grinding on the contact wheel). Also I'm sure there are improvement that could be made over the original design. I'm already brainstorming as to how I could have made it to incorporate a finger sized contact wheel.

Thanks for all the comments:thumbup

I'll try to get an action shot posted of it throwing sparks:D
 
Bruce, great grinder... ingenious and resourceful (and huge!!!).

I am thinking about converting an old surface grinder into a belt surface grinder, and I have heard a few people buying Grizzly contact wheels as of late. But when I got on Grizzly’s site, I couldn’t find it. I have a new Grizzly catalog, and I couldn’t find it in there, either. If you bought it through Grizzly online, can you send me a link to the actual wheel, or if you have a Grizzly part number, can you post it? Thanks for the help.
 
Great, thanks, Bruce. Will do. I really like what Indian George did, so my plan will be to convert my old Norton Surface grinder (isn't real accurate at this point, anyway, but has X Y Z travel already) to a belt surface grinder, similar to what he did. It'll help to hog off more material when surface finishing


IG, hope you don't mind, but I post a few links from your site, showing what you created. Good stuff!

-Bruce- Im a newbie to the metal/knife world- but have some background in woods- and that grinder is sweet.
-Just a thought- I have a woodworking friend who made a similar setup for a vertical sander and found that change of season the plywood swelled and threw off his tracking constantly... He replaced the center post on his with corian (from a scrap at a kitchen refurb place) and the swelling wasnt an issue. He also doesnt have the tensioning setup you do- so that may be a factor- but I just thought I would toss my 2 cents in and say I like the rig- awesome you can pivot the whole thing too!
