Chassis Stand testing - Simon Wa3uay - 08-20-2021

First of all, thank you to all for the compliments.
I yanked the Chassis out of the 90B recently acquired, it weighs a little more than 20 lbs.
While the stand is sufficient as is, I am going to lengthen the foot 1-1/2" for better center mass.
Also will probably include the hardware.
-Simon

**EDIT** for dimensions
Philco 90 14.75"L x 10.25"W x 2.625"H and 7.50"H overall (overall Height is to the highest point- in this case, the top of the Power Transformer)

One of the larger chassis I work on are 1938 Zenith 9 & 12 tube chassis (same size).  I was going to test the size limits of the stand but these chassis have a ridge that prevents the fixture from sliding on:
   

So I shrunk the chassis stand down as far as it would go and it did accommodate my tiny Detrola 4 tuber (model 4D):

   

Great job Simon  Icon_thumbup  Icon_thumbup  Icon_thumbup Thank you!

Thanks John; I think we can make a 'mouth' for that profile, but I need more details...and pic of the inside

RE: Chassis Stand testing - RodB - 08-21-2021

So I was wondering how to mount a German made chassis like a Grundig which has a dial glass wider than the chassis. I can see from John's photo that it could work mounting it by the rear chassis panel.

Rod, I had to use the rear panel because the controls on the front of the chassis were blocking the fixture.

Simon, I'll email you some pictures and measurements next week when I get back home, thanks!

RE: Chassis Stand testing - Simon Wa3uay - 08-23-2021

Yes, I'm finding that the Rear of the pan works better than the Front on some radios- so that is an option......
I did that to this little 5-tube Motorola 51A, but I had to grind out the 'tang' on the sliding back stops...that's one change I shall make.
   

RE: Chassis Stand testing - Phlogiston - 08-23-2021

I just got mine!

Feeling a little foolish - 

After spraying the metal with a little clear lacquer, that I just happened to be using and assembling as shown - - I had a hard time picturing how to mount the chassis. If you look at the picture above - no problem. I just could not picture it before. I think that I expected the chassis located somewhere closer to the center of gravity - in the holder rather than above it. It isn't and it doesn't need to be, but I think that ,if this were to be marketed, that picture above should accompany the layout description.

OR - is it just me? Icon_crazy

I've got a little 5-toob Zenith chassis here, one of the early ones, so it is about 10" X 10". I'll give it a try.

I think that there is going to need to be a larger model too - for working on 15 to 30 toob radios. Icon_lol

I wonder if the hardware store has some fasteners that could replace the nuts & bolts that I am using now?

Back in a while - -

5-S-252 -

Did I say small?! This chassis has so little open space on top that there is nowhere for the lower slides to land.

I can see that some people might want to put on rubber edges (bumper strips) so as to not scratch a chassis.

Unless I grow another arm, it is going to be easy for me to bend the mild steel tangs.

I'll try some other chassis from the wood/parts shed but probably not till morning.

RE: Chassis Stand testing - Simon Wa3uay - 09-10-2021

Russ, something that small, one could employ magnets I bet....
John, on that Zenith this new version could (might) work (see attached). I'm a little worried the PT will touch.

Thanks, Bob! Thats a nice bench you have there. All I have is an old kitchen table Icon_smile

RE: Chassis Stand testing - PaulFischer - 05-19-2023

Hey Guys,
I have a 1964 fisher 400 receiver that weighs 27 pounds. Do you think this chassis holder could handle that okay? Love this idea as the fisher has no easy way to support it on it's back.

thanks,
Paul

RE: Chassis Stand testing - radiohenry - 05-20-2023

Simon,
  I have been using my fixture a lot recently on a variety of different size chassis and am very happy. I think the more you use it the easier it becomes to use set up wise.
                                           Thanks again.
                                                   Henry

RE: Chassis Stand testing - DaleHCook - 05-21-2023

How does one acquire one of those MillerMetal stands? Are they still available new? Are they built to order?

RE: Chassis Stand testing - morzh - 05-21-2023

Paul

The chassis holder is made of steel and will hold lots of weight; 27lbs is not a problem.

The only thing you have to make sure is that there are two spaces at the vertical long sides of the chassis which go into the slots in the holders. Usually there are.
