Drill, dowel and epoxy.

Owner does not want glue.

Sorry Brad. I did read that, But unless you owe him some almighty favour, dowel and resin would be my way or the highway,

Well it is a good friend of a friend. And my welding supplier.

Any luck with this @Brad93 ? Im interested to see the result.

Still undecided what to do

Is he thinking simply a layer of glue on the broken surfaces though?

Dowel, glued in both legs would seem to be the easiest and less damaging to the surface patina. Especially if the patina ends up a molten puddle on the bench!

Heating it won’t be a problem

i would tin both sides with silver solder then heat with o/a holding the flame well back , i did similar to a bronze ? camel with a bent leg that snapped off as i tried to straighten it , worst bit was the guy was watching ,but he seen the funny side and didnt take the hump

if you strengthen (if theres room) with a tube inside first and you cant solder/weld there is bronze powder available that you can load your resin with, this does give the required bronze finish , I have used it on antique garden urn handles where there has been no other option, the main thing being getting the dowel fix strong enough to give it a 100% strong repair first , then go over with the loaded resin purely for cosmetics . Its a nice thing and worth saving , although a time waster re cost effectiveness probably.

I think silver solder, no chance of melting the brass and it will clean up ok in hot water. Ive done a few things this week and went very well. Two tiny brass screw without getting any on the threads or melting them, couple of carbide inserts and chuck.

I need to buy some more silverflo, not sure if its worth getting the 55% or 56, 10 degrees lower temp, stronger, but the tin can make it crack?
Or, there are still some nos cadmium rods on ebay, 30 degrees lower which will make a big difference with the mapp torch.

I would pin it....but drill the pin holes so they are flared at the bottom and use a threaded pin so basically it's a mechanical join that doesn't rely on the glue (epoxy) itself holding.

I suspect as other have said he doesn't want glue because it hasn't held in the past...I'd offer to glue it...but also offer to solder it if the glue doesn't hold. Glue and pin will cause zero further harm...there is nothing to lose in trying.

 

[Brad93]

This is where I’m at. Two 3mm reamed holes. Hopefully I’m going to find a drillbit long enough to drill through the bottom of the base, up into the legs of the ornament. If not I’ll have to order a long series 3mm drill to spot it then a 2.8 or 2.7mm to drill then ream.

 

[Brad93]

You can see someone has attacked it with a grinder before.

I wouldn't have thought that a reamed hole was the way to go. The silver solder needs some space to wick into, and the rougher the surface finish the better.

I’m gonna braze it properly with brass rod and gas.

 

[Brad93]

It’s gone back together okay. Press fit the two broken halves together. Slight mis alignment But it wasn’t easy to hold and drill.
It’s now self supporting on two 3mm dowel pins.

That looks just fine to me, Brad.
Plus, it must be nice to get that little nighmare behind you!

All the Best,
CJ

^^ As it is now self supporting on the pins I would have thought some clear epoxy loaded with brass filings would be a nice safe way to hide the join.

Looking very good so far...doing these sorts of repair I find really satisfying, knowing that it's been saved from the bin.
