Stage stands

[johnfarris]

Hello Folks hope everyone enjoying there bank holiday

I have been asked to make some low level stage stands for a school.
They would like the stands legs to be able to removed for easy storage.
I have used a span table to work out the timber dimensions & I am using structural graded timber.
Thinking that need something on the bottom of uprights

Can any of you folks see any improvements or designs floors that might be a problem?

Thanks in advance

if you made the frame and top board as one, and then had screw on legs, you wouldn't be putting so much stress on the corner joint, i.e. the frame sits on top of the legs. sorry if my explanation is rubbish, hopefully you get the idea.

+1.

I'd make the apron continuous around the underside of the "work surface" with a decent square block inside each corner. Into this block I'd fit an M10 threaded socket and have circular screw-in legs fitted with M10 allthread. At 1800mm span I'd also fit a set of middle legs.

Thanks for the replies
Are you suggesting this arrangement? With mitred corners for the apron instead of butted for anaesthetics

personally i'd like the leg to be under the side pieces something like this

I don't think it will matter if you mitre the apron corners or butt them. That;s pretty much what I meant though. I only suggested circular legs as square ones would need to be perfectly lined up every time they are screwed in.

Hi
Making items for schools is fraught.
3rd PARTY INSURANCE!!!
What age range?
Are the pupils going to assemble/disassemble?
What happens when the joints inevitably work loose?
Bolts cross threaded?
Bits go missing?
Will you be responsible for repairs?
Sorry to be a miserable old "B",
But I have been there, done it.
Cheers John

In response
What age range? - 11 to 16
Are the pupils going to assemble/disassemble? - No Caretakers are
What happens when the joints inevitably work loose? - Why would they?
Bolts cross threaded? - And again why would they?
Bits go missing? - Wont be assembled
Will you be responsible for repairs? - No
Sorry to be a miserable old "B",
But I have been there, done it. - Done what?

I have come across this neat design its a modern version of a gate leg rostra

What do you reckon the thickness of the ply is 25mm?

oddly enough, when I read the original post, was wondering why you were using legs like that, with the inevitable stress concentration where legs join the top. From memory, when 40 year old daughter was doing stagey things in school, the stools used were all of the folding box design shown in later post. For all the reasons suggested by miserable old B. (sorry, John ), that box style has a lot to recommend it over separate legs.

The top wing nut might be difficult to tighten.

I've made many tables in such a way and never had any problems,
but when you add school children into the equation...Enter Mr. Murphy.

I'd go with some 'box style' variant.
