Commlock scratch build

eagle2010 · 01-11-2010, 01:59 AM

Hi all...trying to scratch build a commlock with working screen. Here are some pics of the progress so far. I purchased a couple different versions of pocket LCDs. May have to make some changes to get them to work properly.

The Starlog Technical Notebook blueprints are not actually correctly to scale...sorry to be the bearer of bad news on that one...

MkIXHawk · 01-11-2010, 10:07 AM

They are approximately 90% full size so at the least you'll have to scale them up

eagle2010 · 01-11-2010, 04:41 PM

are there more exact measurements available?

eagle2010 · 04-11-2010, 10:23 PM

The posting "Commlock size myth investigated" shows that the Starlog Technical Notebook blueprints are spot on. Any comments?

Thanks JD for the heads up.

Some more progress. Decided to go with the Starlog prints to just see how it will turn out. Here are some more pics.

I had to go find the thread to recall what I said

I'd still like to see actual measurements of that real prop; shouldn't be hard to settle the issue if it's still in the hands of someone who doesn't mind measuring it.

Well good luck with that, getting measurements around here can be like asking to be shown State Secrets sometimes. In fact it's entirely possible you'll be told who shot Kennedy before being told a S99 model/prop dimension

MkIXHawk · 09-11-2010, 10:29 AM

I applied some logic to the drawings and realised that they were probably likely to be in imperial measurements thus:
Length overall: 7"
Width 2", Depth 1.5"

Antenna Tube 0.75" OD, 1.75" Length

Bottom Section: 1.5" x 1.5" x 1.5"

Screen: 1.5" Diagonal

Gap between sections: 1/16"

Sure, I'm dismayed at that attitude as well when it crops up. But in this case, there's already photographs with a ruler in them -- so maybe there's a willingness to actually share.

eagle2010 · 14-11-2010, 11:38 PM

I would think someone would have the right measurements with the several kits out there. Maybe we will get lucky!

**w8cmp** · 15-11-2010, 07:19 AM

I'm not sure any of the kits have actually got it spot on either, as the makers are all in the same boat regarding measurements.

eagle2010 · 15-11-2010, 09:37 PM

I didnt know that. Thanks. I do have to say that the kits are very well done. I would like to get as close to the actual measurements as possible to compare to the finished Starlog blueprints Commlock I am building.

**w8cmp** · 15-11-2010, 09:57 PM

This seems to be a pretty spot on build / kit. Worth having a look through his threads...

Thanks w8cmp!

Has anyone ever put a working viewfinder into a commlock like the original? I found a 1.5" CRT like the original used made by Matsushita co. for $24.99. Wandered if it could be made to work selfcontained.

NeoGoglu · 16-11-2010, 01:42 AM

Correct me if i'm wrong, but the studio working commlock had a 2'' CRT
screen in it and not 1.5''. The 1.5'' crt tubes weren't available in the
mid-70's.

But if the commlock could have existed for real, it was probably made to suit
a 1.5 crt tube in it.

I built a functionnal commlock in 1997-98, using a Panasonic professional
video camera (viewfinder). Only the CRT tube can fit into the commlock,
all the electonic gear must be placed in a separate stand, and the major issue
is to bring a 200 volts current for the yoke and another 1500 volts from
the flyback located in the stand to the tube located in the commlock itself.

Not an easy task when the commlock is made from aluminium square tubing.

All those pictures below are screen grabs from the WIP.

And the following picture was taken 5 minutes ago, the commlock
is in the middle of various used viewfinders

**w8cmp** · 16-11-2010, 06:24 AM

The screen used working Commlock was oversized to allow the 2" tube to be fitted, and it had all the wiring coming out of the pointy end...

commlock · 16-11-2010, 09:10 AM

The Starlog Commlock blueprints are a fantastic guide, but size wise it's wrong. If you look at the bottom of the page it has a scale guide, cm & inches, measure this & you will see how out it is. All you need to do is scale it up so the cm & inch are the right size. That's what I did & I have put mine next to originals & it is the right size.
Hope this helps?
