Leica GDF321 tribrach in two pieces
Well I’ve got a bit of time at home to try and tidy up. Will hopefully find a few lost bits and a few that I forgotten I had. And mostly just be able to get into my little home office again…
A couple of months ago one of my tribrachs came back in two pieces in the hands one of our talented “apprentices”. I have no idea how he managed it and now I cannot see how the two pieces were ever attached. Are they just glued or pressed together?
I still have the three little plastic channels that go under the footscrew pegs.JPG "DSC_0242 (Large).JPG")

It’s OK I got it.
Those 4 little holes are for turning the top plate from above (with circlip pliers). There is a very short thread that holds the top and bottom plate together.
I forgot to show in the photo as well there is a washer shaped spring that sits between the two to spring load it. -
hello squowse,
start from the left. each piece goes on top of the piece immediately to it’s left. piece 4 will thread into/onto piece 1 to hold pieces 1 to 4 together. piece 3 is a diaphragm spring.
edit: just saw your post. good going.

brilliant, hope you didn’t take that apart just for me!
I’m sure it will help someone else.
the pieces 1 to 5 are numbered left to right?
how does piece 5 fix? are there circlips involved under the plastic covers? -

yes numbered 1 to 5, left to right.
yep, circlips are involved to allow the threads from 2 to come away from 5. when in place they determine the maximum amount you can wind the footscrews out.

Put this back together slightly wrongly when I did it over xmas.
I thought I would leave a few notes in case anyone else has the same problem.a) Piece 1 has the threaded insert fixed to it. Mine had come loose ( I think there was threadlocker there before) so I used a couple of spots of superglue to hold it back in. When mine was broken, this threaded insert was attached to piece 4 only. I think when the tripod screw was (over)tightened it loosened this insert gradually.
b) Piece 3 goes in on top of piece 2 with the spring concave side downwards. It just about fits into a groove / ledge in piece 2. I was putting it inbetween piece 1 and 2 before and it will not allow piece 1 and 2 to be clamped together properly in this position although it seemed OK at first.
c) I used circlip pliers to grip and tighten piece 4 down after turning it by hand for most of the thread.
d) I didn’t need to separate pieces 2 and 5. Pieces 3 and 4 will just fit through the gaps between the footscrews.
