would like some advice on a current project.

How much does the tray wobble when it comes up? Or is it fairly ridged and true?

Hoping to get to Decorex and Focus today too but more likely tomorrow now, always a good show

trays not made yet and will be bespoke. will need some pretty heavy lifting mechanism.
i was in brighton yesterday. a;ways a good day out. what is focus ??
think there will be some good stone exhibitors at decorex. just glad im not doing the dispalys like i used to. Always stressful

think Silicon would stick tony but the joints will be approx 8-10 mm in grouted areas and Silicon may be hard to match sand /cement grout.
anything i use will get rubbed alot if the tv comes up and down regularly

ok understand, how thick is stone?

 

[Tony73]

what if you cut grooce on tile edge on platform and fit in some kind of brush or rubber? or i'm talking rubbish now? :lol:

stone is between 25mm and 48mm thick. you can see on one of the photos how I have loose laid a section out before fixing. overall height of bed thickness and stone 50mm.

tray now fitted and it does wobble a bit when moving in to finished height position.
i have cut the stones and loose laid on top of tray and it looks good.
had to abandon idea of overhanging interlocking stones.
next main problem is to reduce the stone to a thickness that means weight of stone and stell tray does not overload the lift apparatus.
by my calculations will need to get stone reduced to 10mm and it will just break.
main reason being that client insists that one of the pieces is 850mm long . if i could have used 4 pieces less than 400mm then maybe possible.
will bed stone in bal fast flex rubber adhesive whatever the outcome to allow for wobble and tray turning over at 90 degrees when it slides down pit . got a steel mesh on base plate to adhere to.

trying to upload a video so can see better maybe how i need to get a false joint between fixed stone and moving tray that looks same as jointing material i will use.client does not want a gap between main field stone and tray stone when in elevated position.

 

[jonnyc]

video not come up. will try again.

 

[jonnyc]

been trying to upload a video for 30 mins now but not having any luck,how do i do this ?

 

[Tony73]

i think you have to put it on youtube and then it's easy, maby i'm wrong

 

[jonnyc]

i have given up . can only show a picture of stone set in tray and hopefully fully this looks like part of floor
with no hint of what lurks below surface!

as Tony says johnny, upload it onto youtube then embed it in a post. As for reducing your flag thickness, is there a monumental stonemason near you, as they'll be able to machine it to thickness.

not read all the replies but can you not trench cut the back of the stone on a wet cutter then knock out with a chisel?
