5-40 is standard.

Nicely done. It’s fun to use the fab tools for home related fixing.

it may get you within .01

Yeah that'd have to be cast to get that geometry, a similar effect could be achieved with a slot cut into the clamp body and a bolt in the lil swivel, but it wouldn't be as good. Load wouldn't be symmetrical, and it'd get stuck more often... Now if you can cast the things!

Very clever design! I bet you could simplify them when scaling them. Could probably knock one out in 10 operations between the lathe and mill, assuming you have a rotary table, boring head, and time to kill. Funny thing is the half cylinder requires about the same work as the main clamp

Those are "Riffler Files" not needle

Those are awesome, specially for $30

Great tool!

Nice clamps.

Good enough to rough set the rotary, but with a turret mill there is too many variables to trust this for fine tolerance work. Just NO. DIAL IT IN!

Excellent year

Works great for most things that don’t have a tight tolerance. But for anything that needs to be +/- a few thou indicating it in can save hrs later on if your part ends up being out of tolerance

I was 3 years old

Think you will find that is a ‘J’ head unit with its serial number. The other serial number is for the rest of the mill.

Do you have to stone the bed first? Cutting oil?

I believe you could choose different combinations of the upper and lower assemblies when the original machine was ordered.

Sure hope it runs true and the heads in perfect tram

A year older than me ( but looking better😢)

Bridgeport is the original and best. That J number is a factory machine number I think

I've got an 81, a 68, and a 1942 Bridgeport. The 68 and 42 are for sale, 68 has a shaper attachment 😎

How else would u do it😂

Floating your vise.

Excellent advice

🤠👍

What is the angle of the taper on the center bar?

That is an absurdly impressive amount of capability packed into those square feet.

Like it but add the following. Indicate your taper shaft. Make sure it is in the center of rotation of your spindle. Then take your rotary table and mill in your thru bore to make sure that it is in the center of rotation of that device. NOW you are ready.

Exact same machine learned on in trade school and had at work almost 30 years ago

Naturally the stamp stating serial number isnt the serial number

Supposedly sends him something he has no idea whats for

Would've figured year 65 by the last 2 digits. I guess the concept of including the build year wasn't a thing for Bridgeport back then.

Your equipment looks far more used and professional than mine so I will certainly give this a try. 🙏

Look at those twistlocks!!

So rad.

Now put a coaxial indicator on it and see just how far off it really is!

Hi! Could you measure the length of the platen after you shortened it?

Great Deal - I have those sets as well and they definitely come in handy 👍👍

Healthy 👍😎👍

great find and addition

went like how? :p

Very nice microphone. I’m surprised it doesn’t say where it was made.

You also need a step chuck closer for each step chuck size/type.

Well, this is quite the suprise because, I own that console. I bought it as a rescue in NY from a second owner who was storing an obscene amount of mostly damaged broadcasing equipment before it was deemed to be tossed or perhaps sold to someone else. I shipped it to AZ where It has been dormant for the 16 years that I've had it. I have since racked modules and pres (m600 wow) and with litterally miles of cabling I haven't been able to finish restoring it. It was to be the main control room console in my studio. It had some water damage but nothing too bad. I dismantled almost everything and started cleaning. Long story short about 15% into the restoration the reality of understanding that the team of talent that originally set such a piece of equipment into motion was of astronomical proportion and that myself, even with some help, getting it back to even 60% was and is a long shot. As you see from the documentation, there is SO MUCH involved with this console. Something like, 30+ elco connectors. Something like 10 psu. Four or five different types. I have maybe 70% of what I started with left. I had to let go of some of the millitary telephone 1/4 patchbays. I've often thought building a few sidecars or just parting it out but couldn't let myself do that. I'd like to restore it to a basic split in line/tape send/ret console for music production. Also my father was employed by ABC for many years so, they fed us. Looks like there's other ST series owners! Next obviously I have to ask, would you be willing to sell or loan to copy etc.. How amazing is THAT! I honestly never thought I would see documentation on this console. Wild and very cool. Message me and I'll take some picks etc. We can check serial numbers to make sure too.

OMG !! I have an ST 24 at my studio, and a partial book, would love to have a look through these manuals :)

What’s your US cleaner solution?

Where can I find this part? I can't find it anywhere. Thanks in advance.

Replace the spindle bearings

😎

I think I missed a whole tray of cool corner notchers

Well you definitely got him on the right machine. Nothing better than learning on a Hardinge DSM
