The plate on the motor is stamped 4.5 hp. So maybe the china man who built it lied I’m not sure.

The amperage on the motor is probably more honest, and if it is from a residential treadmill, 15 or less. 1.5 actual HP at the very best, if it is 15 amp and the motor is efficient.
4.5 actual HP is way overkill for a treadmill for anything less than, say 4.5 horses...
I think the "shop-vac" HP ratings come from stalling the motor and measuring the current right before the motor burns out (which might be 50A very briefly). It can't even do that plugged in to 110 at your house because the breaker will trip at just over 15A. Note that by definition, the motor isn't doing any work at all when stalled, it is just turning electricity into heat very fast until the windings melt.
Anyway, not trying to rag on you. I am very interested in the forge and grinder and how they work out. 1-1.5 HP will be plenty for knife grinding in any case.

Depends on the knife!!
Jealous!My brother gave me this Peter Wright anvil this morning. It’s in good shape. From the markings appears to be right at 100 pounds.

If you can get a good clear pic of the markings, I'll look it up in my book "Anvils in America" and tell you what they mean. It is supposed to the the anvil collectors BibleMy brother gave me this Peter Wright anvil this morning. It’s in good shape. From the markings appears to be right at 100 pounds.

Looks like it says Peter Wright solid wrought 0 3 15 maybe. And has a D on the foot.

I know it’s rust, but in that photo it appears to be glowing hot.
Peter Wright is an English made anvil and considered to be a modern anvil. The first number on the left is increments of hundred weight (112 lbs). The center number is quarters of hundred weight (28 lbs) and the right number is the odd pounds. The 0 indicates it is less than 112 lbs, 3 x 28 lbs + 15 lbs or 99 lbs.

I'm still looking to see what the D means and to see if there is a way to date it.

Should be done this week. Got the wheel kit and platen in today. I’m at work though so I’ll work on it some tomorrow hopefully.
