A few years ago i made myself Dan Comeau's @DanCom excellent 2x72 belt grinder. It has served me very well since. However recently I have yearned for a little more versatility, especially the use of a contact wheel or various projects. Dan very kindly supplies his version which I am sure is great. However when I researched the £3000 machines out there, I found they used a slightly different approach which I thought might work for me too. Anyway, it turned out to be very cost effective: the steel used was from my scrap bin and the only real expense was the 10" contact wheel I got on Aliexpress for about £50 and the bearings which were another £10.
The wheel I ordered can be found here: https://www.aliexpress.com/item/1685...390e4c4dVX4eo4
Hope this be of interest to some of you. Take good care.
