What Did You Buy Today?

So, I have been working on a number of small parts on my lathe and many of these were too small/short to back up to the face of the chuck face and/or jaws soooo I picked up a Chuck Stop Spider (parallels), looking forward to trying this out....

ought me one of those nifty CNC Bridgeports. Got it for $2500, along with a Bridgeport vice, and a CNC pallet (flat piece of steal with lots of threaded holes for mounting), and Ah-ha control system, plus an Acorn control board. I got it in excellent condition, then proceeded to dump it on its face in the driveway.
:( That was hard to watch . I know all too well about the 1/4" ridge from the driveway to the garage floor . I bought a 8 ft Johnson bar which makes things pretty easy shuffling things around . After flipping my first lathe back in the eighties , I'm well aware these days that machines flip quite easily . Hope to see that machine workable one day soon . :)
 
that was all I was saying. They are a good price, but ultra precision holes... NO.. not for their intended use. As a matter of fact, I don't know if my Mits are precision, but they have screws that work. But if they are 123 they are overpriced.
Didn't get to check mine out fully yesterday. What arrived was two pairs of 246 blocks. One pair looked pretty good, matching parallelism on a surface plate on the 2" thickness to about .0001. The other pair on average matches that, but swings +/-.0001 around the nominal. Basically looks like the grinding wheel was out of balance or something, you can see ripples in the grinding. The better pair has nicer looking grind to it.

Most of them pivoted on the surface plate correctly, one block was slightly twisted. Pivoting on two opposite corners.

Not sure when I'll get a chance to check them for squareness or the other sides. Probably after I give them a bath in kerosene or paint thinner. I agree with @WobblyHand , they stink! There was enough cosmoline to protect them for 10 years at the bottom of the ocean.

Overall, I think the price was good for what's here. I'm sure it would cost a lot more to even buy material to make something similar!

Why are there threaded holes? I haven't found a video that shows why they're there and how to use them.
I have 123 blocks but they spend a lot of time just getting chips thrown on them

The threaded holes are there to make it more difficult to remove the accumulated chips. :laughing:
