Have been left at home for a month while my better half is back in NZ visiting her poor Mum who had the misfortune to firstly break her hip and then have a stroke while on holiday ...
To amuse myself - besides writing sh*t to Ram about eels and orifices - I've got a decent sized to do list of projects ... one of which is to build a suspension bar for the rock rings/TRX and a chin up bar to go into the
personal training clinic that we have in the basement ...
Which is where my plea for engineering help comes in ...
I'm wanting to mount this on the wall between the clinic and the utility room. The wall is 100x50 (4x2 for the imperialists out there) open onto the back. Being North America, there are no dwangs/nogs or whatever else you call the cross blocks that sit between studs in your part of the world.
To get enough space for the TRX to work, I'll need to build a wooden frame that will be about 75cm (30") deep by 100cm (40") wide. I'll be putting a couple of clips (like you find on a climbing gym wall) on the outer face of the frame - which will be used to clip in the karabiners for the rock rings or the TRX.
I'm also thinking about putting another frame over the top that I can then mount a steel bar into to be able to use as a chinup bar. That'd sit about 50cm (20") out from the wall.
The studs are all 100 x 50 (4x2), and sit at 50cm (20") centres (45cm spaces). I therefore should be able to bolt the frame into three of them to spread the load nicely.
I'm guessing that the maximum weight of the people that she trains would be about 100kg (220lb).
So, my questions are:
- what length diagonal bracing am I going to need on the frame to hold it securely?
- are there any crazy risks with my idea of bolting through the studs?
- would I need to make sure that the studs have dwangs/bracing between them at the point where the frame is fixed?
- are there any obvious errors in my plans? (Leaving aside comments about my wood working skills ... I may be a lawyer, but I'm also a Kiwi, so, as the advert says
"DIY, it's in our DNA" ... :tu :tu )
Thanks in advance - and I promise that I'll nominate whoever replies for the most helpful member awards ...
