Why not ask the customer what he wants? The more parts you make new, the further you get into "grandfather's axe" territory. ("This is my grandfather's axe. My father replaced the handle and I replaced the head"). A good soak in Cuprinol, Xylophene or whatever should take care of the woodworm if necessary.

Hi Stuart,
last week I spoke to the owner of the set and he is agreeable to replacing the side panels if there is any doubt about the condition of the originals. Tongue and groove joints are used to secure the panels into the framework. The hardwood framework is untouched by the worms but the tongues on the panels are a bit chewed up in places.
Interesting to note very little glue was used in the construction of the cabinet. Lots of screws and really tight close tolerance joints to keep everything together. OK, these sets weren't made in vast numbers but nevertheless a lot of investment must have gone into the tooling to make these beautifully constructed cabinets.

Hi Dave.

Reading the previous posts, I think there will always be doubts about whether the woodworm will return. It would be such a shame to put in all this work only to find a couple of holes in it further down the line. If the eradication of the woodworm could be guaranteed then carry on but I feel the panels need to be replaced.

We have rescued this piece of history so let’s make it last another 80 years.

Work on making the new cabinet sides will commence later this week.

Earlier this evening the signal generator was connected to the sound receiver unit. The sound receiver is not a superhet as the vision receiver is, but is in fact a TRF, fixed tuned to 41.5mc/s. The receiver down in sensitivity. Supplying the unit with a channel B1 signal direct from the Aurora gives insufficient output from the loudspeaker. According to the oscilloscope the oscillator in the demodulator is operating at 783kc/s.

I'm not surprised that the worm hasn't gone for the hardwood framing ..... softwood [and associated plywood glues] seem to offer the beasties plenty of continuing delight in this particular cabinet!

The sides seem to exhibit plenty of infestation - and as mentioned previously, there seemed to be fresh frass in your original photos' ..... indicating on-going activity.

Under these circumstances, I would definitely replace the sides [and give the framework a good lick of clear Five Star Cuprinol - just for good measure].

It's coming together eh? !!

"It's coming together eh? !!"

It sure is but there is another part of the cabinet to deal with and that's the control panel. It's an easy part to replicate except for one item, the "TELEVISOR" emblem which must be preserved or an exact copy made.

I would certainly want them renewing,not worth the risk at all.

I am sure there that many who are watching this could help with a possible copy or scan of the Televisor Emblem which could be a water base transfer, this is a great restoration as all the others you do with plenty of detail it really amazes me how you and others keep finding what seem to be the holy grail of probaly tvs which most would have thrown away but you David resurect and bring back to life fascinating .P.S,I have meant to contact you on another matter is it ok to PM you I met you at mikeys swap meet regards David

A replacement right side panel was made today and test fitted. A few slight adjustments required to achieve a perfect fit.

The attachment shows the condition of the original left side panel. After removing the lower batten serious woodworm damage was found. The panel is scrap. A replacement was made today.

Re: Baird T5 restoration project.
 
That is the worst infestation of woodworm I have ever seen :o
A while back I purchased a Pye LV20 in very poor condition (mainly for the CRT).
The base of the cabinet crumbled away to dust, what was left had been hollowed out internally. One good stomp on the top of the cabinet, and it broke in to several pieces!

I disposed of it in my wood stove, I take no chances with it when it is this bad.
Amazingly the chassis was in great shape once properly cleaned, and will be saved for future use.

I bet you are pleased that the hardwood frame is unaffected and can be kept.

All the new cabinet parts made so far are assembled together to show the progress I've made with the cabinet reconstruction. Next week I'll turn my attention to the front panel. Lay on new veneers and refit all the detailing parts.

Aghh David, I see now what you are doing. Is the hole in your T5 designed to fit the base of that sickly coloured ball thing in the background?

Seems a shame to scrap the innards of the original T5 just for it to be replaced by that plastic bomb. John.

Hi John
It's a Keracolor colour TV set. Likely to be as rare as the Baird T5.

I'd rather have the T5 David :)

When I worked at an ex rental tv outlet we hated those sets because you could not stack them on top of one another.
Keep up the good work david and get all that infested wood out of the shop , you don't want any beetles making a home in your other sets.

The T5s were bad for stacking too.

Hello Jac,
Thankfully the Keracolor thing is a repair job and it won't be in the workshop for long. Real 70s kitsch.

Hi Robin,
rest assured those woodworm infested panels will be burnt.

Hi Peter,
There'll soon be two T5 sets in the shop. But I better not try stacking them.

The top CRT display panel hasn't escaped the attention of the woodworms.
So it follows a new top panel must be made to replace the damaged part. Pictures show the first stages of the construction of the new CRT screen panel.

Those beasties do look [hyper] active .... bright clean flight holes and plenty of frass! Exterminate! Exterminate! Exterminate! (God forbid ..... this could migrate to the Tardis!!) :-D
