Today I made a handgrip for my Praktica LTL3.
The LTL3 is very big and heavy and in the 70s a built-in grip wasn't very common.
What you need:
_ a grip of a hammer
_ a sheet metal (I used one of an IKEA rack)
_ screws (2 normal screws and a screw of a camera bag (I used the screw of the original bag of my Zeiss Ikon Nettar 518/16))
_ 2 (shim) washers (I used the washers of one of my Shimano XTR V-brakes)
_ bench vise
_ drilling machine
First I cut the wood-handgrip to the right size. Then I flexed the sheet metal, 'cause the sheet was a 90°angle one.
After a 15minutes-work the grip for my LTL3 was ready:
And it works great!
