Metalworking Hunttalkers!

Lotta of the main body of those blades are HSS steel. Given the heavy usage in industry's its a good material. Not exotic by any means but typically long lasting and easy to sharpen while holding good edges.

Just an update on my knife project. My friend the metallurgist reports that my tablesaw blade was M2 High Speed Steel. I gave him some scrap and he tested it and is working out the annealing and rehardening process.



That's the scrap in his kiln/oven... I'm not sure what it is called.

Awesome! When it comes to steel harnesses or any metal really, its always been interesting to see the Industry Scales commonly used despite all convert. Brinnel was one we tested for alot, however it converted to other testing standards as well.

That H scale for HSS if memory serves has a scale of 1 to 5/6 for different applications. Cut a bit of slack, as its been a few years without daily usage of those specs.

I stopped by a good buddies machine shop today. He surprised me with a knife he’s been working on for me. I’m pretty excited. I printed a sample of this design about 6 years ago for him. He’s finally bringing it to life.

My brother's a teacher and asked if I could repair some stools from their chemistry lab at some point over the summer. Had the free time today to take care of it.

It's a shame that states can't use the extra funds for their schools that is wasted each year by the military's "we must spend to make sure we get the same budget next year"

Every year the offices get new chairs even though nothing is wrong with the old ones. And all these Air Force guys talk about how they dump fuel just to get rid of it so on paper it looks like they need "x" amount

Good looking work though

Got a few projects coming up

What is a good multiprocess welder on a budget? Took a hobby welding class, and looking to buy one. Thoughts?

 

[Carl 9.3x62]

Slowly working on a rear bumper for my truck. Will have a swing out arm with spare tire and maybe gas can mount. Put it on today just to make sure it fits before proceeding.

Depends on the budget. I have a yeswelder 200 and I've been pleased with it so far. I dont trust it to last forever but for the price I couldn't justify jumping up to the next tier of machine. Harbor freight used to be the budget no-brainer but they've gotten a little proud of their machines.

Ive been looking at Yeswelders online. Slso been looking for used welders. Thanks

“Anything wrong with it?”

“There’s nothing wrong with it. It ran great 2 years ago. ”

Liar…..


What he didn’t know, was that I too own a few tubes of jb weld….

If I put three or four coats of that JB weld on there with a light sanding in between each coat it will likely hold as long as I don't torque those bolts down too hard. JB weld is some pretty strong stuff and there isnt any lateral movement there, just "vertical pull". The other three bolts appear to be solid still.

Also, it should be noted that this is how I received this motor and I am not planning on selling this motor to anyone. The prior owner or repair guru drilled and tapped those pocket bolts longer to get more threads up into the casing. I did wonder why a couple of those bolts were non-stainless and seemed to be extra long...Kudos to the guy who did try to do the repairs before me as he was at least gentlemanly enough to use a liberal coating of anti-seize on the bolts and they did some out relatively smoothly.The next place for this motor will be the junk yard.

I got the boat/motor/trailer for $2,000 the other day and I tore all of the wiring out of it and then I went to replace the water pump and noticed this issue.
If the thing holds for 2 years, I will consider it a win. I might get out the tig torch and fix it properly the next time I go to do a water pump change but for now, I am not 100% certain that this motor is going to last 1 hour so I'm not putting too much effort into things.

So far I am ~ $200 deep on repairs. With paint I will be all in at $2500. If I get 25 outings on the boat without something exploding or sinking, I will consider it a win. The motor does start and the trim does work. So I got
that going for me.

Just a little "JB Metal" work here and there....

I'll post a photo if I get the things running this weekend. When I started it up (briefly), it smelled like a mixture of burned rubber and burning oil....lol
