T.S. Isaac Frame with stuck stem
Purchased this T.S. Isaac Stratus frame with a severly stuck stem at Classic Bikes Auburn. Started working on it on the 4 th. Seeing its steel took a center punch and put a mark where it goes into the steerer. Penetrating oil ,tapping on it, a 24 in pipe wrench, and time, figured i would get out it in about a week, it laffed and said no way. Welded a nut ot the top of it, so I could use an impact wrench and slide hammer, more penetrating oil , clamped it to a porch post at the fork crown with a c-clamp , pipe wrench to keep presher on it while using the impact wrench on it for 2 more weeks. Tonight board up between fork blades to crown to the concrete, smacked it a few times with a bigger hammer broke the nut off ,thinking to myself is this thing ever going to give up. Thinking a few harder love taps can't hurt at this point, checked the punch mark. Eureka punch mark has moved slightly down into the steerer, I'm winning. Clamped it back to the post leaned on the pipe wrench a little harder and hear the sweet screch of sucess, 30 min later the frame is free of the ugly stuck stem.

Aside from really really long rides, really really stuck seatposts and stems are the most satisfying part of this stuff. Imagine having to repaint that T.S.Issac—THE HORROR.

Awesome save!
If you have not done it already, remember to run a flex hone through the head tube to ensure you get any additional corrosion out before you treat it with a rust proofing product.
What a great looking frame!

Yes , sweet success! I once spent a week removing stuck seat post and stem on my $20 Motobecane. I was able to save the stem and seat post , have the frame powder painted and ride. Not a particularly rare frame but I love riding that bike just because I conquered the stuck items.
