Good grief! Those are very thick!

You wouldn't get much spring with those!

[leelee970]

That's pretty thick flooring Dan, you expecting a nuclear war?

Not a bad price though.

Remember to make a few access panels, just in case you need to gain access under the floor for some reason - I had a rat (dead after I set poison) to remove.

[Daniel-K]

the price is great so i think i will go ahead and order a few for the floor

[Daniel-K]

sweet just ordered them! well thats a heck of a saving for the floor!

would 9mm shutter ply be ok for the roof??

You may require hospital treatment when you finish shifting those about.

yes but i know its going to be solid

[Steve Ward]

Could be a problem with it retaining heat built up during the day and the associated warm air rising.

[Daniel-K]

even though its ventilated underneath??

[Steve Ward]

At that thickness probably.

[Daniel-K]

to fair though our temps never get to hot and if turns out to be the case im only £50 down and its an easy fix

[RogerTheDodger]

Handy if you have Elephants come round to observe - you know the floor will stand up to it.

I have three removable panels in my floor - to access the pier-to-desk cable run. I'm glad they're not 45mm thick, they would be impossible to lift out.

I think we used 18mm Far Eastern Ply for the floor with 4x2 joists at 14" intervals

They look good at that price, I think you could do away with a lot of floor joists. Nice find that's a great company for cheap materials and local too. I wonder how heavy they are, I have some fire doors that size and they are just about manageable,

Brilliant price for such thick Ply Danny, I can't imagine its marine ply for that price though, are you going to treat it? my obsy build is a shed conversion which came with 12mm tanalised tongue and groove floor to which I've added 6mm marine ply, so 18mm total, and this feels pretty firm under foot so far. I think I'm going to finish the floor with some ali tread plates like these:

so a total of 20-22 mm for the flooring with supporting timbers at 12" centres which should be pretty solid, so I recken your 45mm floor might be ok:D

I think you might need more!

[nightvision]

Fewer but stronger joists me thinks (could be more like a block & beam floor), it will be interesting to see how much they flex under their own weight....

[Daniel-K]

i added more joists yesterday as a precautionary measure got a quote from them for my cladding T&G 12mm thick £180 they seem very good and next day delivery too

I'm not sure Ali tread plates are such a good idea, not very forgiving if you drop an EP.

Also there is the issue of condensation; my pillar gets quite wet at times so I can only imaging the same will be true of a metal floor covering.

Then again I could be wrong.

[leelee970]

Make sure you seal the T & G as best as possible , especially the prevailing wind sides.

Mine have let in a little water due to this awful weather (lucky the P.C. and laptop were no where close).

ah but you also could be right! although I'll be using a dehumidifier so hopefully ths will help a bit:) Good point about dropping kit though, maybe I could have rubber matting around the immediate pier area? I don't own any expensive eyepieces at the moment though just the Revalation Plossl set as I mainly image and now days do visual with bins, quite like the whole both eyes thing:D

There is another thing I'd worry about with a metal floor, water/condensation and that is adding 240V to the equation, mind you I am talking about my wiring skills.

All my electrics will be introduced and kept above the floor level, although maybe I should just lay down some bathroom lino instead, it will be slippy but at least it will be easy to keep clean and cheap?

I wonder what Danny has in mind for covering his 45mm ply floor?

[leelee970]

Sorry Dan - stealing your post here - myself I've used carpet tiles, very cheap, easy to cut and glue down and not too bad at keeping clean - also they have saved a few dropped EP's

[Daniel-K]

i will be using carpet tiles i was going to line the inide walls with pvc sheets then ply the inside to make it bit more water tight if anything got through the T&G how did you seal yours ?
