The video was done 2 years ago as part of a kickstarter projrct. They are now up to version 2 which is shown in the picture. This machine is great for small parts and the company is now selling these for $4900. This is what cutting edge is all about.

The engine block is tiny. By the time they get to version 3 I should be ready. 😁

Surprized that they can sell these for $4900.  There is a lot there.  Do they quote an "envelope size" anywhere?

Found it - 4.55" X 5" X 3.55" - large enough for a 1/32 chassis

Im thinking of this mill in addition to my mill for other chassis parts better suited for this machine like achshalter and motorhalter, etc. Items that are not flat.

Similar to these which are made from aluminum. If you have seen chassis like those from Scholer, DoSlot, Slotfabrik or Scaleautos Klasse 1 chassis the rear assembly is made up of 4-5 parts. I could make the same thing with one part.

Let me explain something here. The parts above can be made via drawings done on a drafting table and don’t even require a CNC mill. Only about 30 years of machining experience. I would even say making one piece would take the same amount of time that it would take to design this in CAD/CAM and the time it takes to cut on the Pocket NC. But that all goes out the window when you make five parts exactly the same and you’re working on something else during the cutting process.

Dot’t be fooled by the videos either, most are running at x4. Cutting on these small machines as is 3D printing a sloooooow process and will soon seem like watching grass grow.

This excellent rear assembly designed by Michael Niemas which is three parts (motor plate, motor holder and rear axle holder) can be replaced with one part. If I am not mistaken they are three parts because of the setup required and not because they are used anywhere else.

Beyond that if I change the motor attachment I can adjust gear mesh without having to disassemble the piece. Remember this car would not suffer the violent crashes that cars have to withstand in our races so there is more leeway.

Haas Automation has many videos showing several topics on CNC machining. The video below shows a very practical use of 5-axis machining. The major drawback of 5-axis machining is having the proper CAD/CAM set-up and tooling.

Haas started their business make a 4-axis add-on even before they started making mills. For what I plan on doing a 4th axis would be really useful.

 They sure did. I own 2 of those units and they're indispensible.

Is this the same Haas who owns part of the Stewart-Haas NASCAR team?

I heard they weren't going to make yardsticks any longer.

Phil, I just checked out your website after reading that. I didn't know you made your own gears. I thought everything was outsourced to China these days. Cool!  :good:
