Silly? Clever? Ampmaker (UK) has announced a new line of reusable threaded turrets for proto boards.

It would be clever if you were constantly rebuilding your amp,but as it is it seems kind of silly.However,as they stand you could drill,tap and install the turrets into a garolyte board in one step on a milling machine.
Other than that I'd say silly.

It'd be handy for adding a turret to an existing board without taking it out of the chassis (assuming you could reach underneath with some kind of wrench).

The internets told me this means...
"... that those who will come after us (the descendants) will decide if something we did was right or wrong, because they will see the effects..."
I read that as meaning : it'll be someone else's problem :angel

ummm---- am assuming there is supposed to be a nut/washer to hold it in place. Or is it threaded into the board material?

M2.5 nut.

Might work better if they had used a fat course thread on the bottom, to just tap into a board. Playing with nuts is kinda silly alright :laugh:

For FYL
EXACT :grin:
may be we can read also "È pericoloso sporgersi" the same way
reading it as "is dangerous to go out of the traced road" experimenting with new unknown tracings
In spite of this I think I, you and we all here like to experiment with new "roads" :grin:
For Simonallaway
it'll be someone else's problem
NO that wasn't the meaning
the meaning was we can decide about only into the future when lot of people has hardly tested this new item and discovered all advantages and disadvantages :wink:
For Mresistor
I think that a board with hold in place nuts will be fine to make prototypes but don't know "if the game is worth the candle" the board will be expensive and probably there are other disadvantages in the practical use
For Billcreller
Do you mean something like a self-tapping screw ? if so, as to be used safely, the boards must be of an adequate thickness and material don't you think so ?

Actually I was thinking of a coarse thread tapped into the board, like a 10-24 NC thread, for example.

Yes, I think that if the board is adequate in thickness that can be do
Nice idea
Also I have an Idea for a new type of turret
a fast to install turret
instead to be as the standard or threaded they would have a blind rivet for mounting
so they are not reusable but are very quick to be installed
and can be used also in mounted turret boards
make a hole, insert the turret and simply pull
Kagliostro
p.s.: may be inserting an adequate mandrel in a standard turret will do the job, but the turret must be used in a less thick board as to assure the base will enlarge enough

Once you pull it the pin drops out
I don't think you can solder them

:kermit: rivit rivit. I myself would put a washer on the back of the rivet to keep it from damaging the board but I don't see why it wouldn't work

For supro66
those in the photo are blind rivets and they are there only for an example of the part that would replace the thread in the new turret or the lower tubular part of a standard turret
not intention to use a rivet instead of a turret
(those are also aluminum and must use a special metallic alloy to be soldered - there are also copper rivet, but what you will obtain is like an eyelet)
may be is possible to extract a mandrel from a blind rivet and insert it in a standard turret to use it, only must use the turret in a board thicker than the standard of the selected turret because the basement must increase the size to block when the mandrel is pulled
For rafe
Yes there is the possibility to damage the board
for that reason must have a mandrel of adequate thickness (not too much sturdy) and a board less thick than the standard (or a purposely build turret with a lower tubular part more long)

Why not brass screws with lock washer and nuts
from Amazon .com
Brass 330 Machine Screw, Round Head, Slotted Drive, #1-72, 1/4" Length (Pack of 100)
$10.73

For supro66
someone was thinking a way to be able to mount additional turrets in a board already on an amp
I was thinking to the way to have a quick mounting turret
so the idea of a "turret rivet"
washer and nuts are good but very difficult to mount without extract the board from a finished amp
