What Did You Buy Today?

[WobblyHand]

Finally these were delivered from far, far away.

A 22mm R8 gear arbor and an R8 FMB22 arbor to go with my face mill that I got earlier. You can see I have some gear cutters, well you can see one of them on the arbor. Now I can try my hand at cutting a gear. With the FMB22 arbor, I can use my face mill! Lots of fun to be had. I am pretty sure they are both 7/16-20 threads, but only the FMB is marked that way. I will have to go check both of them.

Also got some Bud Boxes for my ELS project, a 5x7 and a 10x12, the small one for my controller and display and the larger one for the stepper driver and stepper motor power supply.

Also some small M8-5 connector pairs, (panel plus mating cable type), an IEC power inlet with fuse and switch, and a power cord arrived today, for the ELS as well. There was some small electrical stuff that I didn't bother showing, like little polyurethane board feet, and some tiny terminal blocks.

And last but not least, a 12" piece of ground 303 stainless rod showed up. 1-1/2" diameter. Found this in the For Sale section on HM. Bought it just to have on hand.

Post Office tried to do a number on the rod package, but the contents arrive unscathed thanks to the good packaging.

All in all, a pretty good haul for the day.

Phew! Both arbors are 7/16-20! Thank goodness. Can't wait to try this out.

I visited my buddy this morning and he made a very good deal on a handful of goodies. His dad owned a machine shop in the 50s & 60s, and these are some of the things he held onto and finally decided to sell. He has other cool things he's not ready to part with. The tap wrench was his dad's design and something he sold in quantity. It is well made and spring-loaded. It has 4 sizes from 3/32 (by eyeball), 1/8, 3/16, and 1/4". It was too cool to pass up. The larger threaded (3/8-16) fixture plate is stamped F.O. Bacon 1939.

The indexer only has one plate, no name brand, and no collet closer for the 5C collets. Next to the indexer are the jacks with several different tops. There are three of them.

Added a NOGA indicator stand and Mitutoyo dial test indicator (angled face). Wow...now I understand why people rave about the NOGA system! The Mitu seems really smooth and I'm sure it will be good enough for me for a long time.

I got some IBeams when I bought my Mill. What are they used for?

Those are machining parallels…

I’d kind of guessed they were parralells of a sort, but hadn’t seen them like that before. My set of parallels (and all others I’ve seen) aren’t an ‘I’ shape and don’t have holes drilled down the length. Are these built to take larger weight, hence the ‘I’ shape?

(I should say I’ve only had time to skin through that video so far, so the answers to my questions may be in there)

Someone here with more knowledge can answer… how to or what they are used for is not covered in the video… or why the shape…

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.
