Mike,
Paint tends to darken with time. In 30-40 years, everything will probably be back to the color that the NOS bed was,
I bought my 3996 new in I think 1982 (I recall the dealer saying late in 1981 that they were out of production). I envy you the larger garage. Mine is only about 600 square feet, about 200 of which is closed off for the radio area.
Did you actually buy the last bed? I was told that I bought the last follow rest. And was too late for the last rectangular tank coolant system. Should have bought it in 1982.

What kind of radio area? I used to be really into CB until a few years ago. Used to run 2k watts out of the garage on a 5/8 wave. I built a 70 foot crank up tower that took me 6 months to finish. It's at my dad's now but rarely cranked up. Used to talk skip all over the country on AM and SSB. Finally got tired of it though and sold it all. I still have 4 100 amp power supplies I built for running class C amplifiers in the garage. Now if you're an amateur radio operator then you don't like anytbing I just wrote haha.
Now I just race my Mustangs and play with machines.

My understanding on gears is... The cast iron gears dampen vibration and noise but steel gears are stronger.
As for gibs.. I had to make some and it was a real learning adventure.
Cutting them from steel stock, tried cold rolled and hot rolled. They curled like a banana. Had to cut it way thick and keep flipping it, machining just a bit off
each side and using force to straighten them up enough to flip for the next pass.
Haven't tried putting them in the oven. That might help!
Cut some from brass. Same problems.
Finally got some in brass and some in steel good enough to scrap flat but even scraping tended to make em curl.
Lots of people will scrape the old gibb and put shims behind it to fit. Nothin wrong with that.
I would have done so but the original gibs were so mis-sized and crappy I deemed em trash.
The brass gibbs I put in my lathe seem to be working fine, haven't had to make any adjustments since installation, but after getting more use on em will pull the slide off and have a good look.
I understand that steel is better than brass but cast iron gibs are the best for low coefficient of friction as well as for dampening vibration.

Nitmare,
I've been a ham since 1962. The radio area is a combined operating area and maintenance area. At present, the only equipment in the operating area is a TCS-14, an R-388/URR, an AN/URC-35B, an AN/PRC-47 and a BC-312-D. Obviously all ex-military. It occupies about 1/3 of the space. The other 2/3 is taken up by test equipment and work bench space.

Ya both my boys love being out here with me. They will love the new bigger garage even more I'm sure. I plan to have the corner area setup with a flat screen and some stuff for them to do so they can just hang out in the shop with me all the time if they want.
The pan is a 14 gauge stainless steel pan that I made similar to the original specs but a little deaper and 1 inch wider... with the 1 inch being offset towards the operating side of the lathe. I did this so the QCGB levers wouldnt be so close to the pan and hopefully prevented my fingers from being smashed over time lol
