Bit fancy for the maintenence shed at work but thanks anyway.

Ive decided,

4.2m x 1m, 2.5m lift and close to 3.5m draw (I think thats the terminology thats what the bloke said down at the timber yard).

F17 KD hard wood with easy tread brackets 14 steps , 240mm deep and 170mm rise.

I'll get started in a couple of days, got an electrical fault to sort on a Cushman tomorrow and just had a tractor catch fire so got to check the insurance and see if I have to rewire that as well.

another requirement is that you should not be able to pass a 125mm sphere between the treads (see JohnE's post)
178mm (rise) - 45mm (thickness of tread) 133mm and that means you will need to put backs on the treads or less rise 15 steps 166mm rise - 45mm tread = 121 no back needed for treads but an increase in the distance out from the wall 3600mm

Sorry I forgot to have mentioned that I have got the ok to move the aircon so I have 3.5 metres to play with now so I dont have to put in a landing.

yes this one has progressed,
you have obviously worked out the standard dimensions for stairs, especially in the workplace. its easy, once you have done one you'll want to do more!


Sounds like you have a plan, with those, easy tread brackets you'll knock it up on no time, don't forget to give it a decent anchoring point, heavy gal angles, bolted to the stringers and dynabolted to the floor work well.

Yeah thanks heaps guys, im hoping to get started this arvo, I have acouple of electrical gremlins to sort out today this morning in a cushman and a few other problems with a certain tractor named Bashful.

DON'T forget to use tie rods to keep the stringers from spreading, and the treds falling through. I think the code is for a maximum of 1.2 to 1.5m maximum distance between tie rods.

Good luck,

Ken

Ok I was actually wondering about that, do you just use a length of all thread about 3/8 be ok?

Yep threaded rod, nuts and washers, on both sides so you don't pull it out of shape,
but if you are using the easy treads brackets, they have ,from memory i think two bolts per side or three, not sure, so you could get away with just them as the bolts will lock everything together, there won't be any spread at all, and don't forget you need hand rails as well.
as the nut said, the code is............but I don't know how picky things are in vict.
