I am guessing they are hardened steel, and perhaps further work hardened. Even the flange was super tough. It’s been an interesting journey through my various tools. HSS was a quick experiment. Some of the garbage inserts break very quickly (it’s an interrupted cut due to the huge runout). Some did okay. I switched to brazed carbide partly because: I don’t have much use for them otherwise and have a bunch; and I have a Rockwell carbide grinder and wanted to try out the green wheel on it. It’s working out okay; I just have to resharpen a couple times per roller.

if you have a bunch of brazed carbide , look for a c10 or al10 depending on brand, I have a bunch from an old machinist, and when I looked them up, good for hard steels and interrupted cuts... so I marked them with a marker so I would remember. Just walked over to the stash and pulled one out to tell you.

Thanks. I don’t remember many markings but I’ll see what I can find.

Last few days i've sent few hours a day for finish the 206 and i'm call it done. its a simple car but took some time manly because i had to do everything alone. The final stages was putting the interior back together, changing the rear shock absorbers, hooking up the LPG system testing it for leaks and a lot of cleaning. Now it needs an inspection couple of license plates and is good to go. i've forgotten how light on its feet it feels, with only 75hp this thing is as fast as anything in the city. Increasing the compression was a very useful mod that i've done to this car, makes the engine much more responsive also sounds much different.

Looks like you've done a superb job, both inside and out. What are your plans for the car - drive it yourself, offer it to a relative, or sell it?

Finished a little CNC project for my neighbor. He lost 3 of the little brackets to hold the leafs on his dining room table. Good opportunity to practice my Fusion 360 and knock out a few parts on my Tormach 1100MX. Getting faster at Fusion, but still a long way to go.

I can't take much credit for the outside, i only did welding and rough bodywork. The mechanical, electrical, A/C did take lots of work. As i've mentioned before this car belongs to my brother and his wife, under the blue paint everything on it is from the orange 206 with which they have sentimental attachment, but that one had title issues, so this was the cleanest way to solve it. As far as i know the plan is for my brother's wife to have it ready when she decides she's going to start to drive.

The one I happened to grab is an Iscar IC2. The other grade I have is Iscar IC70.

If I am reading right on my phone, I think the IC70 may have been a better choice. And I realized by the end that 100 sfm worked much better than 400 sfm.

Yesterday was car repair day. My son bought a classic 1997 Mitsubishi 3000GT and we are working our way through a few of the major issues to pass inspection. One of the main items was the parking brake. It did not hold well and the handle inside was loose and would not tighten. When I pulled the seat and console and got a better look I figured out the mountings nuts had pulled out of the body. I figured I could either weld some new plates in and try not to light the car on fire or fabricate a plate and secure to other points. I went with the plate and it turned out all right. Also replaced the pads, one side was seized and there was no lining at all. That part is like new now. Rear motor mount to go and then we will see what else pops up.

I made a machinist jack out of 304:





I elected to use holes for a 4mm bar to turn it.

Finished all the posts beams and sill plates for the shed.

Not sure what the actual rules are, slipped this one past the building inspector as its a low occupancy building, for a shop or house you need to have an engineers stamp on the plans. Was surprised. Got to love rural.

Greg,

That shed will be built better than my house!
