Getting old and lazy. I bought a 355mm cut-off/chop saw to save myself some tedious hand hack-sawing. Built a rack for my 500-series Tektronix oscilloscopes. The lower two positions will carry my pair of 545Bs, the third from the bottom my 575 curve tracer, the fourth my 551 and the very top rung will carry the 551's power supply unit. For now the frame is brushed down in a phosphoric acid based rust converter. I'll let that dry over night and give the frame a couple of coats of gloss black "Rust Guard" epoxy enamel tomorrow morning.

Nice. But are you sure those little castor wheels are up to it?
You might find it worthwhile to add screw-down pad feet at the corners, to take the weight off the castors when it's left in one place for a while. Otherwise the castor wheels develop flat spots due to plastic deformation.

Resistance decade box - bigger than I thought it would be.

Also, I orderd 1 ltr of MG Chemicals Rosin Flux a couple weeks ago, it got delivered somewhere else (not where Amazon said it was) and I claimed against them for the loss and was refunded. A neighbour brought it round today - took her time! Still, can't complain - I guess it was free in the end..
Nice resistance box, I have the same one.  :-+

Specmaster, beautiful fab job on that scope rack!  Just be careful moving it about - I bet that sucker's gonna be pretty top heavy once it's loaded up with 500 series Tek scopes!

Probably not the brightest idea. But saw a 3458A with 002 for a somewhat reasonable price on fleabay.

I actually experimented with stability when determining the width of the outriggers for the castor wheels. The rack unloaded is easy to tip, though it may not look it perhaps, when loaded it is in fact rock stable. There is a lot of weight bearing down on the center line (most of it coming from the pair of 545Bs at the bottom) and to topple the rack you'd have to leverage that weight over the fulcrum point of the outer castor wheels. Not easy and you'd never do it by accident.

Almost gave myself a hernia loading it this evening. Lots of ventilation here and all of the side panels are easily accessible/removable for routine calibration. Hmm, I was getting nice and toasty sitting on the chair next to this equipment rack just now.

Wow, that equipment rack looks good, but the contents look even better! You can charge admission!

I am thinking of hitting the music stores for a used 19" rack on wheels for my coming Vectorscope monstrosity.

I always use the desktop view; in this case I forgot that the post had been quoted and simply scrolled up till I saw the pictures and used that post originator's name.  In this case I was a post or two too far down, and didn't notice that it was a quote.   One additional thing to try to pay more attention to in the future.   :-+
