I Did it! Hard 3M 5200 conquered

Several weeks ago I asked for your advice and counsel on removing pipe stantions imbedded in years' old 3M 5200. Thank you. I solved it with the pictured tool - a 3/4" bolt with a 3/8" pipe thread on the end, run through a U-shaped box to the stantions, each with a female 3/8" pipe thread. The second photo is the tool in place, lifting a stantion out of the gunwale by tightening the 3/4" nut. Some were more difficult than others, but all 16 of them came out. To my surprise, I did not need heat.

Re: I Did it! Hard 3M 5200 conquered

Good deal. Over the years I have made, altered, customized and occasionally purchased tools to accomplish some weird job. Have accumulated a selection of altered, cut off and bent wrenches, super long screw drivers, oddball brackets, altered gear pullers and such which I may never use again.

5200 when a steady force is applied and held, seems to give up. It will hold strong to a strong short time force like smack it with a hammer type of thing, but apply a steady force like prying for example and it seems to let go.

A little heat and it lets go fast. Albeit not always possible to do.

Re: I Did it! Hard 3M 5200 conquered

Actually a guitar string (E I think, I don't play) with wooden handles on each end fashioned into a garrote. You know, like what the Corleone family used on poor old Sal (aka Fish later on TV) works just as well. Get the string started on one end or corner and work it back and forth just the wire saw that came in your survival kit.

Re: I Did it! Hard 3M 5200 conquered

Hello

Have not seen DeBond mentioned. I believe it was designed to soften 5200.

Also.....a stiff metal putty knife heated (hot) will cut right thru 5200.

As they say in Swiss watchmaking....

Use a larger hammer."

I didn't understand how the tool worked either.

I will be using DeBond to remove a large port that I bedded with Sikaflex. Then I will try the wire saw and if worse comes to worse I bend a saw blade fixed to my little multitool sander.

That's the spirit.... I also often look through my ton of steel scrap cutoffs, my stainless steel profiles collections, etc.... and BINGO.... I discover the right piece that can be machined for the job.

Re: I Did it! Hard 3M 5200 conquered

Picture #2 is on its side. Turn it; the red bar is my gunwale, the bolt is straight up, with the bottom end of it, the end with the pipe thread, screwed into a pipe stanchion like this one. The 5200 is between the stanchion and a larger pipe that it is inserted into, so no wire or chemical could get to it. Sorry; I forgot that you might not have seen my original plea for help.

Yes. Whole locker full of Harbor Freight tools cheap enough to modify for special purposes. I tried to patent the Mark I TKL Stanchion Puller, but someone laughed.

IMO your pictures are too zoomed in to give a prospective of what you did.

Regardless, congrats on achieving your objective through ingenuity.
