I don't think I can show the whole thing right now because I'm still working on it. I spent almost an afternoon driving a short shaft with a diameter of 25mm and a thick-walled steel pipe with a larger diameter. They are then pressed together by a press and welded together for reinforcement...

The hexagon punch tool made some time ago is feasible to actually use, but because of the small Angle, each use needs to adjust the small drag plate to increase the bias Angle, and recently more use, so I am determined to make a new one. First make an auxiliary tool (eccentric clamp) This time...

Now the new design has been completed, and some samples have been made. Soon, I will post the photos of the new...

EDM is not used for two reasons: 1.EDM cannot process blind holes. 2. I need to produce a large quantity, and the efficiency of EDM is very low. This little tool is not suitable for using it. 3. I have successfully made the rotary offset shank, and I have successfully made some inner six holes...

I think the use of oxygen cylinders, or carbon dioxide cylinders and other high-pressure cylinders to store air will solve the safety problem, and second-hand is not expensive, but must replace the original unknown gas. I bought a second-hand COCO CO2 cylinder, very large wall thickness, and...
