Shorelines

[Mike Mcdermid]

Can anyone out there in lugland show me what a "classic" shoreline is.

Secondly can someone explain what makes a good un.

My interest in lugs is growing

A shoreline is trade jargon for the edge of the lug regardless of how thick/thin the lug is atmo. Some folks braze the joint and then file the excess filler, small amount that it may be, to accentuate the edge and bring it to 90 degrees with the pipe. According to my opinion, it's more telling to be able to braze clean enough so that you don't remove filler, you simply restrain yourself from adding too much. One method that helps the brazer keep the flow from overflowing is to bevel all the lug edges inboard before the joint is fitted and the torch turned on. That way, a small cavity/valley exists and it inhibits an overzealous run of brass or silver alloy.

thanks for the explanation

Im asuming this from your explanation

not this

this would be the profile with the undercut following the profile roughly if it was constantly at 90 degrees

Consider that some assume the lug edge to stand at 90 degrees to the pipe. I use my body english to
convince the edge to lean inboard, and I accentuate heavily it atmo. If no material bleeds out at all it
will almost appear as a gap to the uninitiated - because the "crevice" between the outer most edge of
the lug at any point and the inner most edge is noticeable, though slight.

I had this same discussion with our community a few years ago. I was told then that the base of the shore line "had' to be at 90* with the tube. That relationship is what constituted "proper" technique. I dissagree in that this is all, at most, artistic preference. Andy.
