Orion/PUK versus torches,
Im going to come in here to post a word of caution.
These new joining machines cannot or are not intended to replace a
gas torch, whatever fuel you use.
They will do things a flame will not do, and a flame will do things
these wont do. So, all you dear folks who are getting excited by
this little Orion, dont bin your torches yet.
To give you an example of what they wont do, despite trying
everything to get the results wanted, heres the spec.
.5mm 999 silver ivy leaves some 15mm by 15mm stamped in high relief.
6 off to be set in a circle joined where the leaf ends touch.
Then on the rear 2 concentric rings of 1.5mm 999 sq wire. again
joined where these touch the leaf backs.
Then the argentium brooch fittings fixed to these.
Then the whole piece is vitreous enamelled several times at 800 deg
C. using a clear transparent varigated green colour both on the
front and back. With no chance/risk of any joints coming apart.
We spent a day with a PUK trying to get the results, no success,
then we sent the samples to PUK head office Germany for them to have
a go. I took the all morning to assemble just half of one. not
So what to do? Back to torch joining. Jig the whole assy in 3 stages
on a carbon block. Solder up using the 18ct white gold paste by
Cookson Gold B’ham, melting point 820/ 850 deg C. A proper fillet
joint in each case everywhere, no oxidation on enamelling, 45 mins to
Another example, a minted reike rectangle also in 999 ag, to have
999 silver shanks both 1.75mm thick, joined to the long sides to make
a ring. PUK just wouldnt touch it after 30 mins of trying at highest
heat setting. waste of time. Same solder as 1 above less than 60 secs
to assemble. Again perfect filleted joints. Has to stand forming
after soldering into a circle.
Hope you all follow.
