I'm looking at a 3 phase 20" jointer, and the guy has it running off of 220 right now. He starts it up with a smaller 1.5 HP motor attached to an idler pulley, before engaging the start button on the jointer. It only produces between 1/2 to 2/3 the rated 8.5 HP.

How effective is this set up with an idler pulley and starter motor? My other choice would be to get a phase converter, so either way there's added cost to be factored in. Which route would cost less and/or provide better performance?

The machine has been completely reconditioned 5 years ago, but has its original 8.5 HP motor and was used primarily in a shipyard. All the knives and cutterheads have been sharpened. The asking price is $1800 CDN, is this too high?

Also, operating costs for a 20" vs. an 8" jointer. Are they significantly higher for your electricity bill? And for sharpening the knives, how much more will it set you back?

Thanks,

Aaron
