    Garden / mowing tractor any built these days with a horizontal shaft engine

    I kind of bought a tractor by accident (a Kubota BX2230 at an estate sale). I needed a mower and it was close enough that I could drive it where it needed to be. Turns out I did need a tractor! I don't have the front end loader that many do, but the mower deck and 3 point accessory connectors on...

I was looking at this picture; Brown & Sharpe Microval 343 Manual CMM - CMM Technology Installing braces to form a triangle for the bridge and that very tall tower as well as strapping, would be good.

    Tips on Moving a Benchtop CMM

    Looks like an air bearing system. You don't want the bearings rubbing against the granite during shipping, so If you can get something between them (sheet of paper?) before you strap everything in place.

    Optical instrument for PCD insert's setting

    A handy method of killing side reflections in a tube is to use a coiled spring (around 10mm pitch, maybe 1 or 1.5mm wire thickness) inside the tube. The spring should be flat black. Common is bras with a black finish.

    light source for optical flat

    A cheap green filter and most any light source will let you see bands. More monochromatic lights will enhance the contrast. If you are actually measuring, you need to account for the actual wavelength (color).
