I have a few old buckets around with brushed motors. Have replaced the
bronze bushing with sealed bearing and replacement brushes.

4HP=2.9828 kW
I(A) = 1 kW × 1,000 / 120 V
I(A) = 1,000 W / 120
I(A) = 8.33 A
So, generating 1 kW of power at 120 volts will draw 8.33 amps of current.
After looking at this, I may never run my Shop Vac again.

I blew up old bucket-vac by putting a larger diameter hose on the
intake. This raised the air flow and the amps it drew, and apparently
tripped a one time thermal fuse about 9 minutes into a 12 minute job.

Hello Gene,
4HP peak is probably more like 2HP in actual use. They’re probably measuring
peak current draw during startup and extrapolating that to horsepower with the
clear intent to bamboozle the unsuspecting consumer. At 120V, 4x750W is 25A.

I don’t think the 4hp is going to tell you much besides something to search for
to look up other comparable shop vacs. 1hp is 745.7 watts, so 4hp is 2982.8
watts. 2982.8W/120V = 24.86A which would be crazy. I searched for a 4hp shop
vac and found a porter cable one that advertises 960W.

With apologies to Douglas Adams, is there a way to make axis treat the A
tables rotation as a rotation the xy plane about the x=0,y=0 point?
This would be very useful in visualizing the progress of a part being cut on
the A tables face when it is mounted face up on the xy table, which is my

Hi Gene,
Yes, it is possible to set up the C axis - I have just done
it on my machine.. When I fire it up again tomorrow, I'll
let you see the ini file, its not completely straightforward
as you have to make the machine ignore the A and B axes..
