Some heat is generated from the lye - aluminum reaction, but I don't know if it's enough to damage the paint. Not sure about the rest of the chemical reaction. It's definitely an outdoor project if you do it.
This link has no TREKs.... https://goo.gl/photos/om6FUVuHkAqnqpR18 - but it has some photos of dissolving an aluminium seat post in a steel frame with lye. Good times.

Hi - I had a frame with a stuck post. Gunnar RockHound. I dissolved it with lye after unsuccessfully using a MAPP-air torch. I was not worried about the paint.

I've been trolling craigslist for vintage treks for what seems like months... Lucked out with this purple beauty! 1985 Trek 560. Looks to be all original aside from cable housing and tires!! Frame is actually in really decent shape aside from normal wear and tear, plus scrapes. The purple is AWESOME! I really like the color scheme.
I have a 1981 Trek 6xx frame that I thought about component switching with this guy but I'm going to ride it around for a month and then decide. A definite steal at $100!

My apologies GB; I assumed that anybody reading "big auction site" would know I was talking about eBay. No secrets there! In fact I was a bit surprised that no one else even responded they had seen that particular listing (eBay item 323204202955) when I posted the pictures here.

.I don't understand the concept of not saying "eBay." They'll say "Trek" or "Campagnolo" or "Shimano" or "Niagara Cycle" or "PB Bikes" or whatever brand names, trademarks or businesses... but then say "the auction site."

This ranks among my best Trek finds yet - I got this 82' 614 and a '85 400 for a nice low sum. They're both the same size - and my size to boot. Each bike had flat bars and mountain bike brake levers. I asked the seller if she knew where the original handlebars were, so later that night she called her Grandma, who had them both down in the basement in the "Donate to Goodwill" pile. She was going to take them to Goodwill the next day - I got them just in time!
If the 614 rides as nice as it looks, it's going in the keeper fleet - I don't have a dedicated touring bike...yet.

Hey everyone!
Wanted to introduce myself to the thread! Currently riding on a ‘83 braze/‘85 paint/decals 760. Loaded up with mostly Nuovo Record (SR derailleurs). I’ll throw some pictures up as soon as I post some more!

You have one of those too? Looking forward to pix of it- Someone else here has a 760 with goofy specs/paint. Figure it was an expensive bike/frame- it may have not sold and got painted and sold later on a sale- OR a factory repair/repaint.

The latest incarnation of my '82 614, now well on it's way to becoming a proper randonnuering bike.
It could use some mid-fork braze-ons (if I dare tamper with an "Ishiwata death fork" :O) and another set of bottle bosses -- maybe in the fall. For now, it makes a fine commuter.

I’ve never heard of an ishiwata death fork. Viscount, yes, but not steel Ishiwata forks.

There have been a few threads about it. I linked to a post in one of them that pretty much sums up how dangerous I think they are. The relevant data is that a few of the Ishiwata-made forks on some early 80's cracked at the fork crown. Many people report having no problems. I think somewhere John Thompson posted a plausible explanation of what the vulnerability was, but all I remember is that it didn't really worry me much. I have a vague intention to check my fork crown for cracks once in a while. I've even done it once.

Some people have had bottom brackets crack, seat stays come loose, dropouts split... poop happens. Seems like much ado about nothing.
