How to deconstruct a brazed frame?
This may seem counter productive, but let me explain.
I collect dropouts, and many of the ones I'd like to display are seemingly unavailable or prohibitively expensive to find as JUST the dropouts. There are a few that I have on damaged frames that I'd like to remove and mount in the collection, but alas they are still part of a frame.
I understand it would be easier to remove from a silver-soldered frame versus bronze, right?
With either, is it just a matter of heating the joint and working the dropout out?
Does it have to get cherry red with an oxyacetylene setup?
Once it's been removed, how can I clean the residual bronze or silver off of the dropout?
How far off are the melting points compared to the steel? I don't want to destroy the dropout in the process either.
Any hints, tips, tricks, or other information is much appreciated. Or, if anyone has any random Driveside dropouts they want to sell, let me know. This is the beginning of the collection, as I only have 9 so far.
That's for the deconstruction wisdom
