[Shop-talk] silver solder under pressure

[Charlie Schlismann]

 I have a press brake that has developed a tiny leak in a pressurized housing in the pump area.   I'm not allowed on ladders (equilibrium problem that sends me down the fast way).  I did climb up briefly and know it's a tiny leak but oil does stream out under pressure.  I'm relying on a mechanic w/limited English.  Tried an epoxy (I hope my guy prepped correctly) and it helps but does not stop the leak.  Web search tells me a silver solder repair is stronger than the parent material (aluminum sheet).  I have AL tig and mig set-ups but he cannot weld.  Will silver solder do the job?  Any ideas?  I can buy a fall harness and weld or braze but don't have the time to clear it w/the insurance co. and they'll probably say NO ladders or climbing.
TIA,Charlie
