Ghosty--I really like what you have done there. As near as I can determine, nobody in North America markets a toolpost mounted grinder like that.---Brian

I haven't seen any 'marketed' either. There are a few other home shop builds +/- size & other features s below. But I really like the compactness of what Ghosty constructed. I hope you draw up some plans when its all done. Or several guys on the forum have the resources to help in that regard.

Brian, petertha, Thank you, I will do a couple of drawings and post, It may take a week or so as I will have to look for the suppliers of the pullies, belt and motor as I bought them some time ago.
The smaller one I built was only for one job, under sized(20thou) bearing retainer rings(hardened) for axel bearings, It done the job but the small bearings started to fail at the end. I looked around for other grinder units and they were very over priced(over $2K) or the shipping would kill me. I don't know what some companies do for shipping but I went to order two small polly V belts from a US company, belts were only small, total cost of both belts were $4.40, $2.20 each, They wanted $119 postage.

Cheers
Andrew

Ghosty--It isn't just Australia. I live right next door to USA and most small items double in cost due to the difference in our dollars and the shipping. I try to always buy from Canadian suppliers. They buy from USA in batch lots and only pay one shipping fee on 500 items.---Brian

Hi All,
Grinding wheel holder, this has been machined to take these wheels, https://littlemachineshop.com/produc...=2585&category=
Some dia may have to be changed to suite the wheel that you use.

Cheers

Hi All,
Motor arrived for the small grinder today, It is going to be a hot one today, mid to high 30's C (around 95-100F), need to make up another motor pulley and machine engine mount plate to take the motor, don't know how much will get done.

Cheers
Andrew
