Changing knives on my TP. Just one to go

[ironhat]

I have read all of the threads on the web (yes, I have read the entire web) and nowhere does it tell how to get the screws out of the knife retaining bar of the Delta TP200. I have but one to go and it's beginning to round over the shoulder. The only wrench that fits is the one that come with it since it is a bit thinner.

I put it to bed last night with Areo-kroil, gave it another blast and just came in from another failed attempt. I'm getting pretty worried. How 'bout another soaking and then heating with a large, electric soldering iron all around the ignorant threads. What are the odds of success?

Chiz,

I'd use a propane torch and heat it up pretty hot. If you can get to it to hammer on it with a punch that might help also.

Good luck,

Is it important to keep the heat isolated to the blade keeper bar as much as possible - off of the drum? Should I use the punch as close to the edge of the flat and in the direction that I want it to turn? And, last of all, would a knock with a flat bottom punch to 'shock' it, much like you would the end of the crankshaft for a recalcitrant blade retaining nut? Do I sound scared? You bet!!

I was able to loosen the recalcitrant bolt by giving it a shot of Kroil and then rolling the roller into a position where gravity would would encourage it to follow the thread. I returned again in 12 hours and gave it another dose. Returning in an additional 12 hours it was easily loosened by benefit of the penetrating oil.

well done. sometimes, the best way to attack a problem is patience and thought. my mchanical engineer dad used to tell me, "if you're working hard, you're doing it wrong".

Hey Chiz, happy to hear that darn thing came out. I was about to suggest that you were a candidate for a "Screw Extractor Set" or then maybe drill and retap.
