What a tough winter here in Ohio! The shop was always cold, my coolant tanks were frozen, The doors and windows were always shut ...it was dark and just plain miserable at times. ...
But at last it seems that spring is arriving and its time to un-roll my new horizontal edge finishing grinder.
I took one down to Larry Harley's Hammer-In last week and it received great reviews.
I elected to use a 2x48 belt which proved to be more economical and practical than a 2X72 due to the over all size of the machine. This one measure 26" long and 12" wide. The 2X72 version was just over 40" long which became impractical to machine in one set-up. To reduce the 2X72 size, I had a few designs that had muliple pulleys to snake the long belt around ...but the multiple pulleys added more cost. After several iterations and a few protoypes, I think this is the most practical and cost efficient design.
A few of the features include quick change contact wheels from 1/2" up to 2" diameter on the small wheel end.
These are the same wheels for the HardCore small-wheel system and have become very popular. The simply slide in and out of the retaining fork.
It also has precision tracking by a knurled thumb screw on top of the springloaded tension arm.
Inside contours and fingers grooves can be ground/finished on the contact wheel....and straight and outside curves can be finished on the platen.
It is mostly made from aircraft aluminum with a Black anodized finish. The work tables, platen and tension arm are steel. All of the parts are CNC machined.
I found that 1X48 belts work better than 2X48 since you can track the 1" belt up and down to use the entire abrasive surface. With a 2X48 belt, you simply wear out the abrasive in a narrow groove and if you track it up or down too far, it will run off of the rollers or crash into the small wheel fork. So, for the best belt economics, I split the 2X48 belts into a pair of 1X48s.
My web site has some brief info which will be updated as the pages are built in the next few days. I should have the final prices by mid week. It will be available:
i) without a motor.
ii) with a single speed 1hp motor.
iii) with a VS DC motor and drive.
Feedback is sincerely appeciated...don't worry about hurting my feelings.
So whatta ya think? Is it a keeper...or boat anchor. Any suggestions, advice, comments.
Sincerely,
Rob
