Wrong!!! The accessories hub has 4 spline grooves but the plastic coupling shaft has 5 splines on that end.
So back to the pulley drive...
Anyone know the rpm's of the mark V drive motor?
I can figure out the nessessary speed by sizing the pulley ratios
On with the show...
I assume you purchased this
Read the second and third sentence.
You need one ofthese
The coupling kit includes the coupler and a hub for the HEADSTOCK shafts.
The spt hub comes with each spt when new.(not much help when purchasing 'used' and it ain't there.
If SS is 'out of stock', PM me and I will send you one to get you going.
Now about them pulleys etc.
The motor shaft is essentially inaccessible, and does not have a flatted shaft end for attaching anything anyway.
The idler shaft runs 1.6x the upper shaft speed. Thus the pulley ratio needs to compensate for that(larger pulley on the bandsaw shaft). A 3:2 ratio would be close(1.5)
Fortunately the bandsaw shaft is quite long.
You will have to size the belt very closely, but tension could be adjusted by raising/lowering the bandsaw in the spt mount(short distance!!!). You would want the belt to barely slip onto the pulleys, and then the bandsaw could be slightly raised to allow the belt to seat into the pulleys.
The bandsaw does not require much torque so minimal belt tension is needed.
With a 2" and 3" pulley, a 18" belt would probably work. A 4" and 6" would require about a 26" belt.
