Re: BOSS to servo's and reduction

If I use the pulley I want on the servo, it is a 17 tooth GT2. I
figured after boring it out to accept the 5/8" shaft that there
will be .116" of meat left between the bottom of the belt groove
and the inside of the 5/8" bore. I hope that is enough meat for
a roll pin to hold without spinning on the shaft. Loctite does
make some high stregnth retaining compounds, but the heating
of the pulley might make them worthless. This would not be an issue
converting a series 1 because the secondary pulley would not have
the space restrictions that the BOSS has. I could use larger
servo motors but I got these cheap and have the proper cables
for them. Mariss states that servos should be operating
at 80% or more of their rated speed to be operating efficiently
and properly. I think the motors I have are the biggest that
Gecko's can operate to their full rating. It all comes down to
gearing. I still have the option of leaving the steppers if
I can't make this work.
Thanks for your help.

the belt on both. I think as least one pulley has to have them. If the
original bore is off center it will have to be bored concentric before
drilling or the bit as you know will just follow it. I havent ran into
that as I use Martin pullies and they are concentric to begin with. To
hold in the lathe a sleeve could be machined with the ID to match the
OD pulley teeth portion and the OD of the sleeve a bit larger than the
flange. Then just split the sleeve in two pieces and use it to hold
the pulley in the chuck.
