I’m glad others responded because I hadn’t seen them before. I assumed they were for setup. I’ll watch the videos. ThanksI got some IBeams when I bought my Mill. What are they used for?

The only I-beam shaped parallels I'm aware of are 'shop made'. You can see they are a relatively simple project for beginners. The I-beam shape and multiple holes allows for use of multiple metalworking machines and processes including heat treating and grinding. The holes allow for more utility when clamping the parallel is desired. The configuration also reduces the weight of the finished parallels which becomes important by the time one has a box full of tools.
When I read your original question, parallels didn't come to mind. If you had included some dimensions or a picture (including some common object for scale reference) your question would have been more clear.

Than extropic. My question was a response to a post further up (which I quoted) which had a picture called ‘Ibeams’. I’d not heard them being called I beams before I read that post. Mine are almost exactly the same as the ones in that post.

That DTI is marked 0.002mm per division if I am reading the picture correctly! That's 78.7 micro inches per division! 0.0787 thousandths of an inch. That's a lot better than 0.002"!Swapmeet find today. $2 each. The indicator works great. It is only .002 resolution but will work great for plenty of jobs. The small bore gages are of unknown manufacturer. Really does not mater as it is a static tool.
Cutting oil is my blood.
