Nice, but couldn't you have made the holes suitable for new posts instead of ordering new plates?
Nope, I only have a drill and a drill stand to use. So I can only drill simple round holes.
The HP/Agilent look-alike binding posts have a flattened side to prevent twisting them. And that as a negative form can only be made with a mill but not a drill.
And I don't have the time nor enough patience to file them into the form needed by hand.
ZOMG!!! You don't have a DREMEL and bits for hand millwork?!?
A 2mm Diamond point or 1.5mm carbide cutter will get you that "D" shape to within a few thousandths and quicker than it takes to finish your coffee.
First, you must have gifted hands that I don't have.
Second, when I drink coffee I mostly use instant coffee. Your equation doesn't solve with me.
On the other hand I'm an engineer.
My profession is breaking problems down to pieces that can be solved.
Sometimes I have to create problems first to solve them afterwards.
Ok back to
my problem:
I have machine milled front plates with holes for binding posts at exact positions.
The holes don't fit the binding posts I now want to fit in.
I only have a drill and a drill stand to use.
With the drill I can widen the holes to the needed diameter.
Because the drill centers automatically I will be able to conserve the production accuracy nearly.
Solved.
Leaves me with the problem of the twist-stop shaped holes.
Hmm. (*thinking*)
Ahh:
I could use a filling piece between my front plate and a backside mounting plate to fill the thickness of the power supplies front plate that is 4mm. Then I could mount the binding posts not only on my front plate but could conjoin my front plate, the filling piece and the backside mounting plate with the binding posts.
My front plate has a step of 1.5mm into the power supplies front plate.
4mm-1.5mm=2.5mm. I need a filling plate of 2mm material I don't have yet.
Ok. Solution:
I'll simply design (and order) three simple plates made of plastic or pertinax with machine milled twist-stop holes.
My front plates drove the price because of the material, the labelling and the mounting bolts. The filling piece will be much cheaper but will perfectly do the twist ...stop.
I'll go for that. It'll be much cheaper than ordering three new front plates and therefore will be saving at least some money for spending on new gear.
Thank you for challenging me.
