Yes.It seams to go in the right way...It's stranger for me hearing that!!! I found the citric acid, common one and not for the chemical use, asking to my pharmacist at few Euros per 1/2 lbs (250 grs)...!!! ??? ??? ???
"I got it" Finally the right torch is on my end. :big:Owewar..I bought two torces..one 25mm and another 18 mm usable with the same handle ...The copper parts are deep into citric acid so tomorrow will be the "trough moment"...!! :big: :big: :big:
Yeah, that is looking good Paolo, Good luck with your pressure test, it appears though tht you should be in good shape, the joints look good visually. Amazing isn't it, what higher heat can do. Yeah, you should be making pressure before you know it. ;D ;D
Yesterday I had a stupid social event and I wasn't able to finish my tube bendere!! Today all was done and the copper tube was ready for connecting the pump to the boiler. After few strokes, the boiler was filled before, I reached 10 bars of pressure but the pressure dropped quickly at 8bar and half:
I noticed a little seep from the pump
tightened the elbow the pressure was dropping again...after a deep check I discovered two drops of water from here:
Fortunately the cross tube are externals ..."Coraggio" (Urry Up) I said and I started another silver soldering session :big: :big: :big:. Now the boiler is into citric acid. Tomorrow the sentence!!!
