What are the dimensions of the vintage RS split top turrets used in plexis (hole diameter and board thickness would be helpful)?

That is a really good question!! - mainly because it is easy to get it wrong!

There are different sizes of turrets, the original RS ones are slightly fatter than the current Harwin replacements

Most Paxolin boards for Marshalls are approx 3mm thick (imperial is 1/8 or 3.175mm)

The RS holes are drilled with a Number 36 drill
(0.1065 inches · ≈ 3/32 inches rounded down · ≈ 7/64 inches rounded up)

Harwin equivalent are 2.6mm diameter and must be 4mm shank length for 3mm boards.

Mouser part number is 855-H2073Z01 (Harwin H2073Z01)

I hope that helps?

That does help - thx! As you mentioned there are many versions and getting the right one isn't easy when you don't have the board material in front of you! That is the exact part I've been eying on Keystone.

Michael at Modulus also sells UK made Harwin H2073Z01 bifurcated turrets, as an option to the RS.
IIRC dimensions and specs are on the website.
(staked them myself and came out great using a drill press setup and staking tool accessory. prep for this summer's 1959 build;-)

I "believe" that the lower row of turrets here are the old RS turrets, compared to the upper row of Harwin turrets.

They were bought as RS turrets anyway (though I don't know for sure, could've been scammed). The diameter of the Harwin (between the two rings around the turret body) is 2.68mm IMG_20220321_105906.jpg
The diameter of the RS turret (if it is RS) is 2.98mm

Yes, I know the old RS turrets need to be thoroughly cleaned with alcohol or something before they can be used. Cheers

The important measurements are the diameter and the length of what goes through the board. The measurement above the board is of less consequence, except for possibly matching OEM stuff. Either way, I'd get my turrets and my board, all from the same vendor to ensure the best compatibility!

Yes, I should have included that they are for use with the 3mm thick board material & required the standard 2.7mm diameter hole. Cheers

Btw - are the RS 433-589 turrets the same as the Harwin H2073Z01?

RS 433-589

Yes. That set is also available from Mouser as part no. 169-3620 . They come with an anvil, but you still need a staking tool to swage them evenly without splitting.

I'd like to know if there's an exact replacement for the ridged tubular turrets used circa 1969.
