I would like to know the spindle speed and position, in order to dorigid tapping. My spindle can be connected to the pulley straight of through the backgear. On top of the head, the pulley shaft is hollow and I can mountsomething in there, but then I would have to account for the back gearand it is slightly messy. I believe that Jon Elson somehow mounted his encoder to a gear inside,which seems a little painful. Does anyone have a good idea?i

It seemed much more messy before I did it, now that I have done it it seems a lot simpler than I thought.See pictures, etc.This was on a Bridgeport 1J head, the step-pulley version. The varispeed version has a more complicated arrangement, where I believe the bull gear moves up and down instead of the pinion. You might still be able to find a position for the quadrature sensors that picks up the gear teeth in both positions. But, the index sensor would have to have a flag that trips the sensor both ways.Bridgeport didn't make this a drop-in option, that's for sure.Jon

How to mount encoder on the Bridgeport spindle?

Loctite 411 is really good stuff. I also use it to stick buna-n rubber sheets to polyurethane blocks.

Much better, but look at this vendor's shipping fee! I'll have to try some of that next time I need cyano.

It seems to be $214.05 for one pound of the stuff, according to the title.

One pound is 453.59237 grams, so this is $0.472 per gram, of $1.42 for 3 grams.

An industrial user could well use this much before it spoiled.

This is $4.34 for 3 grams, which isn't bad given the fixed per-package costs.
