Yes, i also like shoe-lump process of assembling DR barrels. The barrels are one peace each.\, and it only takes one set-up to braze them to the RIB and lump-plate. But what do they use to braze them ?
As i see its some kind of Silver-Paste solder, but at what temperature ? Hi 1,200F.degrees or lower
500-600F. degrees ? I saw Heym and Sabatti videos shoving their process, and the LUMPs never got RED HOT so it means that its done in LOWER temp. 400-600 degrees ! What do you think, did you ask anybody about that ?
