After cutting a couple of brace test pieces on the LR2 out of a bit of scrap ply I had this curious feeling that we’ve brought the new puppy home before the old dog is dead! 
.
My intention has always been to attempt the final ones out of Composite, so rather than waste any energy fiddling with the LR2, I thought I’d try a different strategy for the temporary struts. I’ll sort the final versions after the LR3 is finally tuned. It helps that I have a shed full of tools that haven’t been fired up in a while and need a bit of routine maintenance.
This is probably a viable way of making struts for anyone who owns basic woodworking machinery and if you have a little experience, it takes about the same time as generating the g-code to cut the parts on the CNC (and yes it is quieter and just as much fun!).
It’s not difficult to cut a very accurate rectangle with even a basic table saw. I like to tape parts like this together to make sure they are cut to identical length, and of course it makes for one third of the drilling.
I usually mark wooden parts out on a bit of masking tape so if I make a mistake there’s no mucking around with multiple marks, just replace the bit of tape and get on with it.
I have a pillar drill too, so drilling clean square holes after centre punching isn’t much of a challenge either, just use the first row as a template for the rest.
Of course if I change my mind I can always cut the truss in later.
