I've attached a couple diagrams of my T-T stand I'm building.
I need help on determining the type of metal to use on the L shaped part, 1/2" or 3/4" thick?
the shim thickness and material type
I was going to attach the vertical and horizontal pieces by 4 screws at the L intersection
The loadcellupright .jpg is from aerocon systems and I was going to orientate it horizontally instead of vertically.
I will be using this:
https://www.amazon.com/gp/product/B...d_p=edaba0ee-c2fe-4124-9f5d-b31d6b1bfbee&th=1
with an Arduino Uno.
based upon a combination of these:

Mine is going to include the pushbutton relay igniter from the 3rd url.
I plan to attach the T-T stand to a launcher bottom
I will only initially be testing 1/4A-A Estes engines .
This is just a 1st iteration....
So what metal should it be made out of?
Steel? Aluminum? specify please and the shim too.
TIA
EDIT added load cell pdf
Can anybody comment of the specs of this loadcell? or is there a guise online that can explain the terms and if they are good or not?
