Watch Faces Suppliesrs and Torch question


#1

Does anyone have suppliers for 14 karat gold watch faces? I was
looking for someone other than Rio. My other question is totally
different. I have a casting head for oxygen/propane that pops so
badly that I cannot use it. It is a new head, and I have never used
one before. Should I use different pressures from my smaller heads?
If so, what is recommended?

Deb, Your torch will pop if you turn off the fuel first always turn of
the oxy. first then the fuel.Best J Morley Coyote Ridge Studio

Thanks for the reply. It is popping while I am trying to keep the
flame on for melting purposes, not when I am trying to turn it off.
When I turn it on, I always turn on the fuel first then add the
oxygen, and when I turn it off I turn the oxygen off first then the
fuel. I’ll get a flame going then
shortly afterwards it pops off.

Deborah,

My guess is that you have a needle valve on your oxygen side that is
leaking even after it is turned off.I had a smith torch that did
that.I put mine in a sink of water and even after it was turned off
bubbles came out.You can brush it with soap solution to see if it is
leaking.Best J Morley Coyote

Deborah, I recall this happening to me quite some time ago when I
first started with metalwork. The problem was using acetylene as a
fuel for a propane designed torch or vice-versa. I don’t recall all
the details. I think it was a hoke torch with a larger tip. The
worst it got was to blow out the tip diffuser insert. Sorry I don’t
remember more.

You might try Otto Freis and Jules Borel in Oakland, CA 800-772-3456
and ask them. They are a watch parts supplier.

sorry, i missed the start of this thread but two possible problems
you could be having 1 if you’re using acetolene and the tank isn’t in
an upright position if its on its side the acetone in will get into
the mix and will make “pops” that will out the torch 2 the gas
pressure could be to high and the torch blows itself out 3 the
pressure could be too low and it runs out of gas. my most common
culprit to look for would be a dirty torch even a new one can have
dust contaminating the inner orifice and stopping the gas flow long
enough to pop the torch. opps that was more than two . hope this
helps.

Talk to you later Dave

Your oxygen and gas pressure may be too low. Larger tips require a
higher pressure. Check with the manufacturer of your torch. They have
tables that list the appropriate pressures.

Make sure all the connections on the torch are tight and that the tip
is on tight. Also, be sure the fuel line is purged of any air (if
this is a new unit or an old unit that has been laying around
unconnected to the regulator and gas bottle). Also, if you are
trying to use an Aceytlene torch with propane gas or visa versa, this
could be giving you problems (one can use Oxy/Act torches with
Oxy/Propane, but it is much more difficult to adjust to a good flame
until you learn how).
