I've noted that Sopwith seemed to draw these several ways, 1d early on in my case, then 2d for the Pup. How are yours!

Hi Joe,
Thanks for your kind comments.
Re the plans I guess these would be called 2d, is that right?
Anyway there are no flat sheet drawings so you have to draw them all up that way allowing for bend radii in all different directions etc. I imagine they were originally stamped out before bending up so I would have thought there would be flat sheet drawings somewhere, but have never seen any.
You end up with a bunch of pieces like this that you then have to go and bend up! I have used 4130 instead of the original mild steel plate and the bend radii is really a bit tight by todays standard. However if you try redrawing it with a more favourable radius it completely changes the fittings so you're stuck with it. This was the first batch.
Cheers, Nick
