yes. its a bf20l.
and yes. i buy simple sheets and cut them self. my tools are a simple lever shear, flex bandsaw, some bender and a old bosch belt sander.

I'm a programmer by trade, so i could use a cad and buy laser cutted metal, but i won't work with computers after the whole day on it.

Last complicated parts are the telescopic lift cylinders.


They are located in the big slots inside the frame.
Big? When you plan and estimate the sizes of the cylinder, the slots gets smaller and smaller

Seldom I've planned so long for a single part. Maximum and Minimum Angles, posibilities in machining, needed pressure to lift, sizes of the cylinder, rods and pistons and so. So much interdependent variables. I think, the fifth or sixth plan was the base for the first try.
I'll show you the second and last attempt
