10" Utility Grinder

[platapus77]

Just picked up this bench grinder for cheap. 10" wheels and only powered by 110 volts. It seems to have good power once up to speed is very stable and literally has a 6 min coast down. However, getting up to speed is a little slow and I am not sure if it normal or if the ancient capacitors are to blame. My problem is I cant find any values on the old caps to replace them with, anybody have a value I should start with? There are currently 2 caps in parallel.

The grinder is a beast and ways at least 150 lbs.

Hi and welcome to GJ! Sorry I can't help with the electrical. That's a great looking grinder. The badge is neat too. It would look great restored. I googled "the united states electrical tool company" and got some links to vintage machinery and others to the current existing company "the US Electrical Tool Company" You may be able to get info contacting them.
