well if it comes out it has a direct route into your engine

pop rivets do the job!

I have seen the middle bit of pop rivets go through as well, - upsets loads of things. best thing is to get a new butterfly made

pop rivets can come out too.  At least if the liquid metal breaks and comes out then it's much smaller than a rivet.

The ideal solution is to get a new throttle plate with no holes in it made but this isn't as simple as it seems because they're not just flat round plates, they have an opposing chamfer on each half of the plate in order to seal.

I think i might have a 45mm butterfly laying around, when i did the test on my 45mm throttle body to get the angles right on it - i'll have a look.

I originally used rivets but then changed to liquid metal.  Never had problems with either really, rivets will still cause a bit of a restriction though whereas with liquid metal you get a flat smooth surface. 

Using liquid metal, make sure you put a good chamfer on both side of each hole (so the cross section of them would be egg timer shaped!) or else the stuff will just slide out when it's set. 

Rivets fail all the time when they are subjected to vibration and movement.  I remember one person posting once (years ago, might have been the old PSD forums) saying that a rivet had fallen out and caused damage to the pistons.

So dont have the holes flush with the plate but sunk in a bit on both sides? I'll give it a go. It'll only be for a while until I can my hands on a 51mm tb.

Will you need to sort of smooth it round the edge of the circle [holes] onto the plate on both sides or will it have enough inside the holes to bond to? [if that makes sense]

no, have the liquid metal flush with the holes so it fills in the chamfer too.  The chamfers stop the liquid metal from sliding out.  It doesnt have to bond to anything, the egg-timer shape of the chamfered hole means once the liquid metal has set it cannot come out.
