Since we are all making guesses -----

Maybe the announcement will be asking for testers.That would be interesting!

Maybe the announcement will tell they have given up on releasing this year.Hope that is wrong!

Maybe, as we hope, it will be available soon.Right on!

Think about it. A new motor, two new pulleys, maybe a new idler shaft and a new poly-v belt. Maybe a new motor pan.

1. With the speed control 'pork shop' mechanism being removed, what will hold the idler/control sheeves in position firm enough to take a belt traveling 10,000 rpm? So some sort of modification to the idler shaft will be required.

2. Is the single v-belt going to work well under additional torque from 10K rpm? When I took apart my headstock that has had very little use since I had a factor work-over conducted, there was no sawdust, but a good deal of black dust from wearing of the v-belt. A poly-v seems more suited.

3. If all the sheeves are not removed, are there any additional issues with them traveling at 10,000 than at 5200 rpm?

If they do switch to a poly-v on the lower drive, some new additional mechanism will need to be installed for belt tensioning.

And, tool-hunters comment about whether all the bearings in all the different Mark 5/V machines--from greenies and brownies through greys--will handle the new speeds is right on.

So, I don't see it being easy or "relatively inexpensive."

So some sort of modification to the idler shaft will be required. There appears to be a grooved pulley (for a poly-v belt) that will be added there. That pulley could have a set screw to lock it to the shaft.

2. Is the single v-belt going to work well under additional torque from 10K rpm? When I took apart my headstock that has had very little use since I had a factor work-over conducted, there was no sawdust, but a good deal of black dust from wearing of the v-belt. A poly-v seems more suited. It appears to me that the motor drive belt will become a poly-v.

3. If all the sheeves are not removed, are there any additional issues with them traveling at 10,000 than at 5200 rpm? Don't understand the question but it seems that speed ranges would have been a design requirement ultimately solved by the new pulley/belt arrangements, the speed control and the variable speed motor.

If they do switch to a poly-v on the lower drive, some new additional mechanism will need to be installed for belt tensioning.

And, tool-hunters comment about whether all the bearings in all the different Mark 5/V machines--from greenies and brownies through greys--will handle the new speeds is right on. What old bearings. The motor bearings will be new, the idler shaft bearings will be new and the quill may need to be upgraded (maybe), the drive sleeve bearing ($100.00+) and all that is left is.

Easy for me to say. I have a new Drive Sleeve Assembly and I am just hoping that there is no bearing change there.

So, I don't see it being easy or "relatively inexpensive."
