Found out yesterday that every company/trade on the job site I am on was to provide something made by them for our Christmas, Oopps I mean trades tree.

So I bent up and tig welded an angel out of 1/8 AL tig wire.

Had a little trouble welding the wires together.

Here's the styli I bought, 18 bucks, genuine Renishaw. 2mm shank, 3mm ruby, 24mm shank length, 33mm from base of threads to ruby tip, love ebay, retail for this is 99 bucks. It has an m5 thread, I'll get others in the future but cheap is the name of the game.

I also ordered a 2" round of 7075 aerospace aluminum for the probe body, if you go through a metal supplier, 7075 is about 3x the cost of 6061, 7075 is the stronger better aluminum, less gummy, machines better

I'll have to check eBay. Unfortunately, I had already made the probe for a M3 thread. When I did the design, I looked at what was available and went from there. I have no idea which thread size is the most popular.

I am not expecting super accuracy for locating position. From what I have been able to find, even the active probes are only reliable to about a thousandth and I can do better than that with my edge finder and spindle mounted DTI.

Mostly, I am doing for the challenge. Like you, I am interested in the ability to do digital profiling.

there is a bunch of different threads sizes, so if I am unable to get a new one of the same M5 thread when I break it or need a longer styli I will just make another spider, that was pretty easy to do, the setup was the most time consuming part, having to put my super spacer on the mill, but it has locating keys so its generally quick, unless the part is long enough that I have to remove the kurt

my ebay search was Renishaw styli or stylus

I made a circle cutter for my dad's bandsaw:





The compartment is for the pins and small hardware that he will lose anyway.

I see our fathers have the same affliction!

That pocket is a great idea, I may need to incorporate some into my various jigs.......
