I have had a Tunturi deluxe door gym/"pull-up bar" mounted in the doorway for many years and would prefer to have it significantly higher (about 20 cm above the door trim, almost so the top is touching the ceiling). Other variants are screwed into the studs (e.g. https://studbarpullup.com/wp-content/uploads/2021/01/image1-3-scaled-1-2048x1536.jpg, and
which also used boards to attach the door gym), so I thought it should work with this one too?
Here is a picture showing the principle of the originally intended installation: https://hefitness.se/images/zoom/multi-training-door-gym-model.jpg
There are three studs, one in the middle and one on each side of the doorway. It is an old wooden house from the 1910s, with a wall that is 9 cm thick (the door trim is 11 cm). I thought I could attach boards (for simplicity's sake, we can assume it's one board from now on) 2.5 cm thick to the three studs with two screws in each board and stud (so a total of six per board), and then attach the door gym to the board with the two existing holes where the circular bar meets the rectangular piece and two new ones lower down on the circular bar. Then attach the board to the studs with 15 cm screws (5 cm through the bar's two components, i.e., the round "tube" and the rectangular piece, and then through the board and about 7.5 cm into the stud)? Could get some support from the edge of the door trim if I mount the boards all the way down to it, I suppose.
I tried to sketch down the idea here, with the bar, doorway, studs, and proposed holes and screws:
What do you think?

I don't believe it. It's quite a significant load. Drill through wall and stud, put a plank on the other side and fasten everything together with screws, washer, and nut. Then it will hold, I think.
