Homemade tool and tempering.

[taumac]

Necessity is mother of all invention. It middle of doing a tile job in my master bath I said there has to be a easier way than a hammer and chisel to get up tiles and remove remaining thinset so I created this.
It lasted removing all tiles and thinset without breaking once. Now doing other bathroom and it removed tiles and halfway through broke. I rewelded it again but the reweld untempers tools. So question is how would I go about retempering it?



Have a good one, Gerard

The only parts of that tool that need a temper are the edge, and the back side.
Neither is anywhere near the weld, and I wouldn't heat treat it at all after welding in the middle.

Or, you could just try a Spyder Scraper in your sawsall.

Temper = to soften the material, increases toughness, decreases brittleness
Harden = makes material less pron do deformation, but more prone to cracking (brittle).

Both are heat treating processes, what do you want to do?

I guess temper cause after I weld it it seems to break. I this happen with this and homemade drill chuck I made for a hammer drill.

Ill tried the grout remover from them and actually make grout remover in my is oscillating tool works better. Does that scrapper work for removing old thinset? I used a hammer and cold chisel and its a job. This tool is just less labor. This is what I'm trying to get up.

Ok think scrapper your talking about will pull this up
That's tile adhesive or mastic
The gray in previous post is this

You can pop tiles off in one piece with Mastic but if a tile guys did a proper tile job with thinset. They're coming up in pieces. I know this just from doing the 5 tiles jobs on houses I lived.

I could just but a electric demo hammer but unused air hammer and cheap flat cold chisel works. Its just the impact over time break the tool.

Milwaukee Hackzall, you can buy 2 different scraper bits (or attachments) wide or narrow.I've used the **** out of them without any problem.

Gotcha, on the simple you could try burring it in a box of insulating material right after welding, to slow the cooling rate. It wouldn't be as hard as just welding and letting it air cool. You're not water quenching it are you? Otherwise a good soak in a oven at ~400°F would reduce the hardness quite a bit. Downside is that you would end up softening the edge material as well.
