Looks cool. How much do the materials to do that cost nowadays? Have to figure the value of the item as to whether or not it is viable I guess. Otherwise everyone probably has a bunch of chicken head knobs in the junk box. For a very collectible radio, seems good.

That is one problem: if you only want one knob you have to buy a lot of materials that usually have fairly short shelf lives.

He makes it look easy but I understand there can be problems with air bubbles so often vacuum is used. Then for knobs with grub screws you need brass inserts although some just tap the plastic. This is poor as its relatively soft and doesn't take a screw thread well.

Here is a set of knobs made by someone who had the know how and experience (I suspect you make some bad ones at first :) ) Charged me 30 Euros (roughly £s) which to me was excellent.

BUZZ1151 made a knob in one of his videos. The first one didn't turn out.
I bought some knobs from Renovated Radios and they seem to be made with a similar process.

I have made some using that method, but one at a time. Making the knob look good is pretty easy. He makes fitting the knob look easy, but it isn’t. Added to the challenge is concentric knobs, such as TV channel/fine tuning. All knobs are not flat on the back. Many have stems exposed. That is another challenge.
