I am considering making a pull-up bar to attach to the wall above a door frame. The house was built in 1946, and the walls usually consist of some mixture of wood and plaster.
You hang from a pull-up bar, so my question is whether the wall can hold the bar fastened with about 6 strong screws, maybe even through-bolts. There will almost exclusively be shear force on the screws since I plan to have the bar close to the wall. I weigh 80 kg.
I've done some sketching. Blue is the bar, and yellow are two beams. Pictures taken from the front and back of the wall.
Behind the plaster, there is a 2-3 inch thick plank wall. It can support quite a lot if you choose the right screw size. However, I don't understand your sketch. Don't you need some form of brackets?

I'm thinking the two wooden beams are something like these https://www.byggmax.se/45x120-kortregel-p08145121, standing against the wall, and I drill holes in them that fit the bar. This will keep the bar about 10 cm from the wall, which I think should be enough for the forearms not to touch the wall/door frame. The body will be free in the doorway. I'm thinking of a 26.9 mm commercial pipe: https://montano.se/product.html/handelsror-1m
Possibly, I should have two crossbars as well, to attach to the wall more easily.
What do you think?
