Compartmentalisation - he doesn't trust anyone not to dive in ahead of him and Patent the thing(s). No-one gets to see the whole story....
Once told, a patent is only as good as the money you can afford defending it. Far better to get it out there and at least make some money from it.
Perfectly true.
Also you can guarantee someone somewhere has done it before!
I patented a new kind of computer joystick when I was 19. Only later to discover it had been patented back in 1880 to control a Glasgow tram!
Jorge Spraeve has an amazing new repeating bow - operates like a pump shotgun. He isn't bothering to patent it. Getting it into production instead.

Superglued 3mm sheet alu to my previous error and turning to correct size 74.3mm, which will mean rear bearing will be floating from its seat by 0.3mm.
What is this alu sheet, Ive got a fresh sharp tip and it turns like sticky dogshit, pushing out instead of cutting!

Try an HSS tool with a fairly steep top rake, you can get HSS sharper than a carbide insert. I always seem to have more luck anyway.

The ally sheet is probably in soft state to allow it to be worked hence unpleasant to machine

These carbide are Walter branded, ground to a very sharp point for alu. A few have said about HSS but Ive not seen anything close. Have an example?
Carbide can be ground with a diamond wheel unless you mean hss is less fragile?
Ive got some more inserts in the post to try

Got some time to mill the rough bandsaw cut finish to size and bore/tap for the setscrews. I decided to do both top and bottom so that the retaining sleeve is held more securely.
I still have to work out the best method of getting the coolant to the capto head but that is for a later date.
Pic of the milled holder.
Pic of it on the turret.
Quick hand fed cut on some 50mm dia F51 Duplex to check centre height is ok, seems pretty good although the finish is not the best as the insert was a bit worn, I was feeding via the MPG and no coolant.

It is a DNMG 150408 INSERT.It needs bigger grub screws ?
Is it a CNMG1204 holder, or something bigger?

Headed to the workshop this evening.
First job was to make a peg spanner from an old 17mm deep socket.
It was so that I could remove the left hand thread retaining collar to get the cap screw out.
Next I bored through the side of the cap screw to meet up with the centre hole.
Then I bored through the holder block at an angle.
so that it met up with the centre bore.
I then made a quick and dirty plug for the end.
Then chapped in in.
Set the tool up with the tool arm and did a face cut and OD cut to test things out, happy with both the capto holder and the accuracy of the tool setter arm

Hacksaw a slot offset from centre on the pointy end then you can use them the other way up as well.
