Then rope in No.2 daughter and let loose with the resin gun:

...whilst I watch Hidden Figures with a glass of Wainwright The Golden Beer!

 

Hopefully the resin will stick like the proverbial to the flints and mesh. I'll then be able to lift the whole thing into place like a mosaic tile mat and hang from some resin studs.

It will all end in tears as my mother would say …

OMG! Ran out of the "proper", need a special applicator gun, Fischer resin and had to use a tube of DeWalt stuff that fits in a standard mastic gun.  (Got it free as slightly out of date). 

 

It stinks to high heaven! No hiding I'm doing this in the kitchen.

Generally seems to have dried ok. If the resin sticks to the flints like it does my hands I'll be well happy.

The odd lighter coloured blob (though not all of them) is still wet, uncured DeWalt resin from the tail end of the tube, when it was just resin coming out with no hardener. Maybe as it was a bit out of date? I'll live with it as the tube was a freebie! Resin is horrible to use from a normal gun imho. Much prefer the Fischer, space shuttle esque resin tubes. My daughter couldn't squeeze the DeWalt stuff in the standard gun. With the Fischer gun it's a doddle.

The "towers" are a concern as in where the distance from mesh to flint is such I've had to build up the resin in height to bridge the gap.

Now to try and "hang" one without everything falling off!

Edit: Must get laddo to print up some pads for the clamps so they sit over the "+" of the mesh and don't slip off.

All I got from that was cars & babes, does it for me.

The Everbuild grab adhesive was marginally better than Sticks Like Sh!t but it still slipped a bit. Very like Sikaflex EBT:

The lower ones were a pain.

Then I had a brainwave, use cable ties to tie the flints to the mesh then blob in some adhesive. As I've said some flints are quite thin and have no tail.

I like to think of myself as the Hengist Pod of flintwork!

Craftsman and those easily offended, look away now!

Going to let it set as is then finish off that top bit. The coach lantern going on the two projecting studs should hold everything in place if it all fails! ?

Cable ties are so brilliant - good job with this, very impressed.

I’m still confused why you couldn’t just bed the flint in upright with cement . Just do a few rows a day and point it . Just like building a stone wall . What have I missed ??

Because these flints are quite thin as in not fist size "blocks". Many are basically conical. They've been selected for their feature face rather than suitability for a "wall". Just don't think I'll have the "sticktion" with straight mortar. Hence trying to find something super sticky.

 

Flints are notorious for being impermeable. If you use a cement based mortar it will shrik away from the flint leaving it "rattling" around in there. Water gets in the gap between flint and mortar, freezes, blows and the flint falls out. A lime based mortar retains flexiblity which is why it's traditionally used. I'm using a part lime mortar mix with modern admix. Once in I'm going to overpaint the whole lot with some sort of a sealer. Hopefully that'll creep into any gaps and aid them staying there.

 

Where no man has gone before etc!

You need to try new things even if destined to failure. You've always been rigid and unable to move fluidly... ?

Well...chucked in some M5 stainless studs with more of the crappy (but free) DeWalt resin. Ran a full nut down then another st/st washer.

Then hinged the board with the stones on into position and hooked the mesh over.

I thought I'd worked out the studs so they would project in the gaps. Nope, got 3 out of the 6 wrong! Had to bend the other 3 to miss the flints. Once on then another penny washer and full nut. The fun is getting your finger in and winding the back nut further in to push the flints further back.

I don't think I'm happy with some of the spacings. Might mess around with the bottom left.

Nope. Didn't like the gaps between stones in the lower panel so pulled all the flints off the mesh.

I now have the joyous task of picking all the silicone and knocking all the resin off the back of the flints.


Interestingly the earlier ones in the top panel, that I cable tied onto the mesh, have now set. Cut the ties off and tbh they're ready to be "grouted" with the mortar gun. That is once I put back in the ones that fell off initially! In the top panel the flints are much better orientated and their faces more flush with the surrounding brickwork. The aim all along is roughly a fingers width between flints. It certainly helps being able to see the face of the flint and tweak it.

Well...

Right or wrong I made up a small mix the same as seemed "right" when I was experimenting in terms of colour and the way it moulded round the flints.

3 builders sand
1 sharp sand
1 lime
1 OPC.

Stuck in the bucket and dry mixed really well first with the Aldi paddle mixer. Then wetted with Everbuild Integral Waterproofer, diluted 20:1. Mixed again. Left a bit then remixed.

Most importantly, despite the sharp sand, the mix is easily pumped with it not drying out at all. Must be the lime/waterproofer having an effect and keeping the water in the mix.

Did the half bucket but the original, skinny, Roughneck mortar gun piston broke. Printing a new heavy duty design now in PETG.

The issue is spacing, a bit bigger than a fingers width in places. I'm going to live with it. When a bit firmer I'll go over the mortar with a dry sponge.
