I found some time today to get the entire cabinet primed. So this upcoming weekend I can block sand with guide coat and prepare the cabinet for painting. This is the moment of truth when all that prepping pays off. The cabinet will sit in climate controlled area along with the parts I have already painted. You have to let the lacquer cure so all the solvents are gone (evaporated out). Block sanding this cabinet will take time and imperfections will be takin care of. I sprayed 3 coats of urethane primer surfacer , this stuff is tough as nails and will give the paint job the best foundation .

Hello all, spent all day up at radio shop working on the black beast. Most of the time was block sanding cabinet , once I was pleased with the smoothness and flatness of cabinet panels I checked it for any imperfections that needed fixing. Also sanded smooth the inside area where the turntable goes, that will go gloss also. Sanding the back side and the speaker area as well and those areas will go semi gloss. First I cleaned surfaces good and used a tack cloth also. Sprayed silver lacquer in the areas that the stripes will be. Let dry well and then measured the panels and layed down my fine line tape. Then I started laying down 3 coats of ebony lacquer, let that dry good. Removed the fine line tape , using take cloth again I started my clear coat putting down 4 coats of piano lacquer . I will let dry overnight and then I will wet sand the stripe areas and probably the whole cabinet then proceed to put down 4 more coats of clear. That will do it , in 3 weeks or so I will wet sand doors, and entire outside cabinet. Starting with 1200 grit wet, then 1500 grit wet, then 3000 wet , all time using my dual action sander as my tool of choice for wet sanding. Some areas will be done by hand. After wet sanding is done I will proceed to buff out using my variable buffer using a wool pad. I also have a small air buffer for tight areas also using a baby wool pad. After that is done I will go over the paint job with micro compound and then finally a good car wax like McGuire's. This radio will shine like a Rolls Royce and be just as smooth. This my friends is basically the same process as doing a grand piano in black lacquer. I will post pictures and such as I go though the wet sanding and polishing and assembly. Thanks for looking at this rare radio getting a new lease on broadcasting over the air waves in style.

Great job, going to be a rare beauty.

Ok guys, I spent several hours today wet sanding and buffing out the cabinet. Very little needs to be done like the door handles and the felt that goes in the turntable area. Joe can finish that part of it and install the chassis and speaker and turntable. I must say it sure looks sweet, about as shiny and smooth as you can get. These piano finish's are very time consuming when you having to redo one. I'm glad I don't have to do a grand piano, but if I was offered to restore one I would , that would make a nice pay check for the week.

One of the last pieces of the Norwich restoration project came in via UPS today.

The Little Giant 18-inch field coil speaker was missing when I got this radio. Now that the cabinet has been reconstituted and refinished, and the chassis has been restored, and the replacement chassis for the field coils and output transformer has been designed and built, the final piece is here - the speaker.

This is an 18-inch speaker, 8 ohm voice coil, and a massive and heavy frame. It has a frequency response up to 2,500 kHz so I expect it will be a bit on the bass side, so might consider a pair of PM tweeters and a crossover network in the future. The speaker board shows that this radio once had a pair of tweeters, so who knows.

Gotta get this thing all together and listen to it.

Is that the radio found in the basement of a house in Detroit a few years ago?

I don't know too much of the history of this radio. I understand it was sold on eBay I think a couple of years ago, and the speaker was resold, presumably overseas. I think it turned up in an Estes auction, and was then taken to Kutztown where I saw it and purchased it. Cannot imagine having cut this cabinet in half. Would like to know more of the history.

Here is a picture of the Masterpiece VI electronics all together. Since the Jensen Little Giant speaker was missing Cliff made a separate sub-chassis to mimic the two field coils and the output transformer of the Little Giant. The beauty of this system is that it required no modification of the power supply amplifier and simply plugs into the speaker socket. If I ever find a working Little Giant it can go right back together as it was in the day since nothing was changed. That 18-inch PM speaker is massive and is a hand full to carry!

Lookin like that will be the boss in the neighbor hood, with all that power and style you got yourself bragging rights Joe, that there radio Joe would draw a crowd if you had it going on display somewhere perhaps a High end audio video store . You know Joe I always thought maybe displaying some of my restored radios at the audio department at a best buy or similar store and have them up for sale by appointment only, having them on display with sales personnel only ones to show them off. Do not touch and have roped off , just a thought. I may inquire about doing just that, having antique radios for sale at best buy, the store can get a % of what they sell for. A warranty will be provided and a list of repairmen in the area for service if needed. What an idea hey Joe.

This post is for Fred Taylor. Fred restored three cabinets for me and somehow they all got lumped together, mostly the Mc Murdo Silver Norwich and the Zenith 16A63 Stratosphere.

The third cabinet was the orphan, and was the one in the worst condition, the Mc Murdo Silver Bristol. Installed the best grille cloth I had on hand, and put casters under the cabinet. I do this on these heavy cabinets to make it easier to move them around with much less stress on the cabinet. Just tonight I got the Masterpiece V and the Jensen speaker in the cabinet. So, Fred here is the final on the Bristol Cabinet. Your handiwork is now proudly displayed!

Hello Joe , it's nice to see the McMurdo silver Norwich all put back together. I bet it sounds real nice playing some big band music. All the work you had done on this radio sure payed off. Its look's great. Wish we lived closer, like same city we could have had some real good times working together on these old radios. I was fortunate to have the opportunity to have met you and to have worked on your radios. The Zenith Stratosphere and the Ebony McMurdo radios were a pleasure to work on, as rare as those radios are I may never get the opportunity to ever refinish such rare radios. Merry Christmas Joe.
