    punch and die set

    Thank you for your input memphisjed. you are correct there are faster ways to make this part, like water jet or laser, (im not familiar with angle line?) the goal to make these parts the cheapest possible per part. also notice that there is 1/8" radii on the corners of these rectangles. so there...

    Heat treating d2 getting cracks

    I talked to a local metallurgical place and they recommended soak 2 hours at 1400 then ramp up to 1850 2 hours, remove and air quench with a fan fast no temper. I had the parts wrapped in ss foil so it took a little bit to un wrap them, but I did that in front of the fan. I am thinking about...

    Heat treating d2 getting cracks

    We heat treated some d2 tool steel in house instead of out sourcing. We don't have a vacuum kiln, but tried wrapping them in the ss foil. Scale was a little worse than I am used to. When I surface ground these blocks, was getting what look like small surface cracks. Any ideas? Thanks

    Tramming the mill head, what the heck

    I bought a nice dual dial indicator tramming device and calibrated it. I got the head zeroed out left to right and front to back.

    heat treating with a home made propane kiln

    So i have this huge beefy heavy steel cabinet that is lined with fire bricks, i think they may have used to preheat certain types of parts for welding cracks up for example cracks in cast iron, like an exhaust manifold. it doesn't have any forced air, so the highest temp i can achieve with the...

    update so quick update I have thought of other methods of building this part...i haven't found any methods that are up to the challenge of speed. 500 parts a year, would mean they order 500 parts at one time, i have to beat $2 per part i am finding it very difficult to get ANY aluminum other...
