What might this be??

My guess is you are planning to build a mounted laser that will show the depth of cut depending on the blade used. Or - if the slide works, it can be used to align a drill bit.

I gotta give that some thought. It was not part of the original scheme but some good things happen that way.

Fear not! That is NOT an issue for a couple reasons. First - just how often do you adjust poly-v tension. Second - it's covered in the design. See drawing changes.

The revision incorporates a 6" steel ruler, held in pace by a magnet. The position of the steel rule allows for "calibration"

Remember that this is dependent upon a laser line. I use a Craftsman 4 in 1 Level (Laser Trac) part number 948247 to provide that.

The final version of this will have the two drive shaft holes enlarged to accommodate the hubs rather than the 5/8" shafts.

But from a different perspective...you could just mark the depth of cut right on the blade and read it direct. SWMBO made that suggestion. Gotta think about that.:o

How cum she got so wise after she got married?:D

Remember the lower shaft also moves sideways as well as up/down.])

Actually marking the blade is not too shabby, although any 'applied' marking will easily wear off and not be very concise. SWMBO's typically do not think past the obvious!:D

Speaking of which(the obvious), drill alignment? We gonna bore out the quill etc.? Think bore sight!

This thing worked, sorta, but it is being abandoned as a bad idea. Its' usefulness is limited to times of the day when I normally do not work in the shop. The laser line, essential to the gauge, is not visible in the sun light unless I wear special glasses. Too much fuss.

Just look at how much the blade is exposed - no fuss. If critical, measure it. That has worked well for years now.
