I've been inspired by another thread here on the forum about building a custom portable chin-up and dip station. The idea is that it should be able to stand both outdoors and indoors. I've attached a drawing I've made and would like help assessing the construction and getting the right measurements.
The timber I plan to use is mostly 45 x 120 mm battens.
Examples of considerations:
Will this construction stand firmly?
Suggestions to make it better?
Are the measurements reasonable for a comfortable workout?
I think the 1950 high studs are at risk of breaking when you do your pull-ups, as they should be rotated 90 degrees. Then they will break in the stiff direction and thereby withstand more. I also wouldn't trust the bars if they are also to be made of wood. Round steel profiles should be used there. I would probably have preferred to make it entirely of steel myself, but if you calculate a bit, it should be possible to make it work with wood too.
With the proposed dimensions, 45x120, there is no risk of the back supports breaking. As you have drawn them, they can hold a piece of over 350 kg, as IngAndy suggests, for about a ton. I would make the round bars from a 45 mm dowel (I have some leftover stair railing lying around). It should hold for the Hulk's big brother (< 300 kg match weight). Do not make the round bars too narrow, it will be uncomfortable and provide a poor grip.
