Parts for lower a-arm ready

The parts for the a-arm got ready yesterday.

Thinking in hindsight, they would have probably been faster to make with a manual machine because even if it only takes 2-3min to make such parts, programming and setting up the machine takes so much time that it probably isn't worth it. It's good practise though...

The machine had enough power to get a tap this far before it got overloaded. This particular machine is designed for manufacturing of small parts, so it doesn't have much power for doing something "bigger".

Attach the workpiece, press the green button

Wait 2 minutes and 31 seconds and when the door opens up the ready part awaits. To the left of the spindle (the part that rotates) is the measuring arm for the tools, and to the right you can see one of the 12 tools that fit into the machine.

This machine is by it's real name a cnc turning center, it means that besides turning you can mill grooves and drill anywhere on the outside or front face.

I had to make the threads by hand because the cnc machine wasn't up to the task. Because I had the tap already set up, I made a 8mm deep thread with it to help to guide the tap straight when making it by hand.

Milling the "bolt head" manually. Width is 27mm, just like stock.

The first ready part.

Even when trying to make a race part the resulting part reminds me more of something from a tractor.
It still needs the mounting points on the chassis, the right length from the tube and then it needs to be welded together
The camera lens makes the tube look bent.
