- Now that I have the radio working I need to tear it apart to restore the chassis but it's worse than I thought, this is going to need more that a clean up. Music www.bensound.com
Another great job. It’s nice to see one working to restore rather than talk ones ear off explaining every aspect of what their trying to do. Your on the right path.
Hi Jim, I don't know enough to talk one's ear off 😄
Amen to that. David rarely dawdles and gets to it.
Looks like you had a bit of a battle with this one! :)
This was I think a very early video and I was struggling with a lack of knowledge and recording skills, thanks pi-duino 🙂
Good on you David!!! What an excellent job! I am impressed with the degree you went to in order to make this the most presentable and functional radio it could be. It is a genuine work of art my friend! Keep up the excellent work.
Thank you Wayne, very kind of you to say 🙂
your chassis always look super clean and shiny
Hi Latürnich, thanks 🙂
Excellent video Mr. David. Impressive patience was in his first video to correct the fault and this second for details. I congratulate you on your work, which is technique and an art for restoration.
Hi Luis, thank you very much 🙂
Very Very thank you Sir ji 😊👌👆🙏
Thank you Rssuthar 🙂
Lots of interesting "stuff" at this Part 2 session. Always amazed at the way you manage to restore the "look" of the previously rusted and dirty chassis and components. You do still make me laugh with your patter especially about how "easy" the dial string was. Some really clever tricks with your masking - especially using the punch to cut the tiny covers for rivets etc.
Thanks Kenneth, you are very kind. I do like to make them look new, the purest wouldn't like it but these radios are not worth much so I don't worry too much. Maybe I meant easy by comparison to other dial strings 😄 It's good to pick up some tips on the way, I have plenty from watching other RUclipsrs 😃 Cheers mate 👍
I enjoy watching your videos , Dave. You put a lot of effort into each project.
Those caps are called tubular capacitors. I remember seeing some many years ago. I think they were on VHF mil equipment.
The string on the spindle comes off the bottom of the spindle so it is clear of the opening on the chassis....see 12' 00 on part 1.
Hi binarybox, I just Googled "tubular capacitors" and I'm still none the wiser 😟 I changed the routing of the string later on but didn't show it as I should have. Thanks 🙂
Yes David I know all about purists - used to restore old motorbikes - had a 72 Triumph Tiger and "purist friends" nearly had heart attacks when I suggested repainting parts where the paint had been damaged! :)
I know exactly what you mean Kenneth 🙄😉
I'm in the market for a candlestick phone. Do you know how many people turn them into lamps. I may have to buy the lamp to put it back to a phone.
Dave, Yes, the brass insert into a cylinder is indeed a piston capacitor. It's like a parallel plate capacitor wrapped up or a short piece of transmission line. The further the plunger is inserted, the higher the capacitance. We used to use something like this in tv tuners, however the plunger was a brass or aluminum screw, for fine adjustment.
Thanks Fred, a screw thread would be a good addition 👍😀
Looks really great.
Wow, that's an old video, sorry about that. Thanks FC 😄
Very good job. Most enjoyable. Dial string “That was easy” lol.
Haha... yes it was easy compared to some 😄
Pretty good and formidable restoration work. Best regards from germany.
Hi wthnel, thank you. Hi to Germany 👋🙂

تحفة رائعة عاشت ايدك عندي مجموعة من الراديو القديم محتاجة هذه الادامة الرائعة تحياتي .
هناك سحر في أجهزة الراديو القديمة ، شكرا لك وتحية 😃
May dear you Are vary good in thes rado
Dear. Abdul iraq
Thank you Abdul 🙂
The phosphoric acid disolves the zinc from the brass and leaves copper on the surface, hence the colour change.
Yeah, that makes sense jonka1 👌
Congratulations! You have gone deeper into the woods than I dare go. I'm afraid I'll run out of bread crumbs.
You should see one of my current projects Cosimo, it's sooo much worse 😲
good job 👍
Thanks Ibrahim 👍🙂
A great job well done!!
Thank you Colin, much appreciated 🙂
40's RCA communication receivers used a bunch oh those caps
Oh really, thanks @tamtgirl 🙂
The wire around the tuneshaft is the wrong way round if you look at 4:15 in the vid. At 30:04 it appears to be changed. You also turn the dial into the other direction at 33:00 Interesting :-) . You are however spot on what the tube airgap capacitor is concerned. Philips and Telefunken used these before WWII as well. They live forever as long as the cerarmic ring does not crack. Do not use rubber as it deteriorates to quicky. . Better is poly ethyleen tube cut to size. Or if you cannot get it... use teak or bakelite you can cute it back on your laithe.
Cleaning only with high grade alcohol. No contact cleaner as the brass tube is coated and if that is damaged oxidation will have the C value floating away. Also the cleaner leaves residue that changes the dielectric constant value. Topwork nonetheless. I find myself always mucking about and getting PO. Your voice over makes me feel better about myself hahaha. Keep it going Dave.. greetings, Ruud
Hi Ruud, thanks for the info, I couldn't find anything on these anywhere
Thanks!
Thank you for your support John 👍🙂
I loved these vids, but the direction of the tuning string is driving me crazy! I always wind it so clockwise moves the indicator right, counter-clockwise moves left. I think you would have had better string clearance of the chassis that way too. But I enjoy watching a tech go through the process, problems and missteps included, rather than just show the edited and cleaned up version.
Hi OldWhitebelly, I reversed the cord direction on the control shaft later on so it works the way you say now and gave more clearance to the chassis. I should have noted it on the video, sorry to drive you crazy 😄
@@DavidTipton101 I assumed it was just your preference. Either way, I'm watching to see you do things your way, not mine :)
And they wonder why some people go bald. Restoring old radios is probably a good starting point. Is "Patience" your middle name by the way? Nice work David.
It's a funny thing Graham, I can work on a problem all day no worries but put me in a queue or a doctors waiting room for 30 seconds and I get frustrated 😰 I guess there are different types of patience 🙂
@@DavidTipton101 Yeah that's absolutely true. I'm extremely patient when it comes to problem solving because I'm just wired to do that and make things happen. I'm not so good however with things like time wasting bureaucracy. Externally I'm cool but inside I'm as frustrated as hell.
@@grahamserle7930 ha ha, yep nailed it
I dont know if you have seen befor, some poiters had a piece of felt at the bottom end .
Hi ajhnubia, I have seen them and have replaced them with a new piece of felt, thanks 👍😃
*_FEW PEOPLE LIKE YOU._*
My wife likes me 😥 hehe... I know what you mean 👍😉
As always, very interesting. Just one question with your Dim Bulb setup. Is it Variac, then dim bulb unit, then isolated power unit, then unit being worked on?
Thank you Don. Variac > Isolation transformer > dim bulb. That way the Variac and isolation transformer are still both earthed 🙂
The coating on the chassis could be zinc chromate or anti fungicide.
Yes, maybe Dave
Cadmium coating, don’t lick your fingers hahahaa
Yes, I wash thoroughly after playing with any radio, good advice 👍🙂
Hi Dave, are you sure the pointer goes into the correct direction when you rotate the knob? I see when you rotate the knob clockwise (to the right as we say here) the pointer goes to the left, and vice versa of course. I would expect to see something different, but I am not an expert.
Hello De Mus, I agree, it is wound the wrong way 🙂
@@DavidTipton101 👍
Dave may I ask If any of the radios you work on can play on u.s.120 volts,I like some of those type of radios .
Hi Ron, the radio will work in the US but it needs 200 to 250 Volts. You can use a step-up transformer to convert the 120 to 240V or I believe most US homes have access to 240V for large appliances like cooking ranges, dryers and air conditioners. The step-up transformers are are cheap and freely available 🙂
Dial bulb to the right looks very bright compared to the left, maybe you’ve put too much wattage in and it could harm the dial?
It does look a little brighter, they are identical bulbs. Maybe just that the dial has more information on the right side to let the light through? 🤔🙂
Hi David, it's me again. :) Sorry for bothering but forgot to ask you what colour of paint and type (glossy/flat) you use or recommend to cover a grey steel chassis with (for my Collier & Beale set). The one you used in this video looks pretty good. Thanks and Happy holidays!
Hi Bj Cuizon, no bother at all. I don't know where you are but I used Dulux Metalshield in Structural Steel colour. It takes 24 hours to dry but goes over rust without too much prep and no undercoat. It looks quite natural once dry and I also spray the tuning condenser frame and It's a good match. Really any paint with those properties will be ok. Here is a link to our hardware outlet in Oz: www.bunnings.com.au/dulux-300g-metalshield-epoxy-structural-steel-spray-paint_p1400828
@@DavidTipton101 I'm actually in New Zealand Dave and Bunnings is also one of the main hardware outlets here. I, however, cannot seem to find this specific product in their NZ site..but will try to ask them in store. Cheers!
That's not a red coating after the acid it's a copper film on the surface because the acid has eaten the zinc element from the surface, brown sauce will do the same thing after 24hours
Yes, that has been pointed out previously John. Is there anything brown sauce can't do? 😀
for the the speakers membrane you should use dope, for the faceplate indicator you can take the end of a cotton swap, to better slide.
Thanks for the tip wthnel 👍

Oh, hi Werner 😀
@@DavidTipton101 Hi David, how are you early on a sundays morning?
It's Sunday arvo here but I'm doing well thanks 🙂
4:26 sawn a piece of an diazed fuse to make this ceramic part.
That would work, thanks 20kilovolt 👍🙂
@@DavidTipton101 You're welcome. Your videos are awesome. 5A fuse seems like a good size to me.
favorite part...How do you use a rope?best regards from İstanbul Turkey
Wow, all the way from Istanbul, thank you augur ragip karas 😁😁
Wow
Thanks 😊
Интересный у вас канал! Подписался на канал и нажал колокольчик ! :)

What ever happened to the translation button here? You'd think it would be better since Google bought You Tube.
That is a sad way to hang him by the foot.
Haha... it would take a while 😄
You Sir must have schematic
I believe I did have the schematic. It didn't have the dial string layout though 🤔
Look for a program called tony cad it a free ciruit drawing program
Hi ajhnubia, thanks, I already have it somewhere, it might be on my old PC. I think it's called Tinycad?
Do you and your wife drink pina coladas?
Yes but we don't gettin' caught in the rain... or yoga 😄
@@DavidTipton101 There is Trident Coconut Cream empty tin on your work table. That's what gave me a clue.
@@cogitoergosumsc5717 Ahh.. right. I thought the pina colada song must have played on the radio 😄
