For our next play I had to build this round rostrum.It will, when the
set decorator finishes with it look like a round pouffe or ottoman.
The shot underneath is to show the studs in the construction. To those
who look at that bit and think 'over engineered' I say only that the
lead female in this play has to dance atop of this thing and she is not
known for her svelte waif like figure.

When it gets dressed and the set is fully painted I'll post more pics.

If someone is jumping on top of it I would recommend resting the beams on
edge on the posts. Looks like just a couple of lag bolts taking that weight.

The posts are placed hard up against the ply and are bolted and screwed
into position. The studs underneath (some of which the posts are fixed
to) are placed on edge screwed into place every 100mm or so.
Myself (no light weight either) and our exchange student tested it by
jumping onthe top at the same time. It didn't move a mm.

I'll look at diagonal bracing after I finish the step. Thanks for the
suggestion.

I think it's UNDER engineered. I see a wicked little racking
problem... especially in the "long" dimension... parallel to the lower
stretchers. I would seriously consider a few angle braces in there.
Might even throw a couple the other way too... unless those carriage
bolt joints are glued, they might rack a bit too.

Holding static weight against gravity is an easy thing... but holding
a person, especially a fluffy one, dancing around on top of it is
going to introduce all sorts of other stresses.

Another thing that I notice.... if the lady happens to step too far to
the long edges, the thing may tend to flip on her. I would add legs to
those edges... maybe like you added to the other two edges.

Other than that.... looks nice... fine job.... blah blah blah ;-)

I'll look at all that thanks. I did have a slight tipping problem in
the first attempt so I added an extra two legs. The six legs are very
close to the edges and I have walked all around the edge without it
tipping and jumped just inside the edge. I'll add a couple of diagnals
to the main four legs going all the way around and then a couple on the
stretchers underneath.

Why on earth did you put some of the 2x4 upended and some flat.
They all belong on end...

Do you mean these?

If so, then I wanted to put two screws in each of the 5 joists. having
them flat made that simpler and stronger. The other two 'below' (when
it is placed as it will be used) are not 35x90s but some 50x25mm batten
offcuts, just as braces so that the four main legs would not spread.

At any rate I delivered it last night placed it on the stage and 2 of
us jumped on it and it withstood that 150kg onslaught easily.

Mekon

Yes those.

Just makes sense to put it on end.
I am sure it is strong, but could it be better? Yes.
