I used a older Maho Deckel DMU 50 CNC machine:-) It's fantastic with such a tool, and when you have Mastercam X4, there is almost no limits for what you can do

Thanks about the comment about the primary holder, I'm almost done with the holders now, but for the moment it's more fun to make the lifting system:-)

Seriously! Im impressed! I want your job!
You have a lot of talent and some serious skills. Did you do your modeling in solidworks? Or something else, autocad mabe?

I do all the modelling in SolidWorks, but for the gears I bought some DXF llibrary's from hobbing.com. I don't have the brain or time to calculate gear tooth's myself, so I go for the easiest way possible:-)

It is a part of my job to be creative and innovative, as I work with mechanical parts for robots and satellites every day. I don't get any drawings from a mechanical engineer, so I have to figure out how to make the parts by my own:-) But that's what I'm there for, and I love it!

Cheers, Daniel

Just a little update on the secondary lifting system.

The first picture is the stainless steel screw, PTFE bushings and planetary gear motor. The motor is just what I had in hand, I will change it for a powerful stepper motor when I can afford it.

This is the final assembly, the bigger disc is 300mm in diameter...
.

I hope to have the internal gear machined this weekend, but I have to go to fight night at the Taekwondo club Saturday, and some training Sunday. So I don't think I can get the time to mount it before next week.

Cheers, Daniel

Daniel,

Your pictures show the mechanism which will enable you to adjust the position of the secondary relative to the primary, in axial direction, in other words, make it possible to adjust the coupling on the fly.
You are building the dream machine!

Hi Finn,

Yes, It's the secondary and not the primary lifting system:-) I'm a bit tired after 13 hours in the shop:-)

Dream machine it is my friend, I can't wait until first light. I'll probably be ready to wind the primary next weekend, so if you have time to help with all the soldering, then I will bring bread and coffee to the shop:-)

Cheers, Daniel

Excellent job!! We can see attention to every detail and every chamfer =)

You said you bought DXF llibrary's from hobbing.com... Can I ask why not to use the SolidWorks toolbox ones?

Hi tobias,

Unfortunately the University only offer the student version to the staff... Probably this is the cheapest to do, as there is a lot of people using this out there:-) And I think that I would need one hell of explanation to get the Professional version:-)

Cheers, Daniel

Alright then! Probably you are using the SDK version (that does not have the toolbox). But if you have the Student version the toolbox and browser need to be activated at "Tools - Addins", at least for the software selled here in Brazil.

I just asked because I aways use the toolbox gears and after you post I though if there was a reason not to use it! hehehe

If you need any help with SolidWorks just PM me..

Again.. Great job!

tobias,

The version of SolidWorks I got, only have the bearing calculator and cam library:-) But I don't mind that, Ive been working with this program for 6 years now, and I`m happy with it.

And now for one more update:

This is the assembled bottom of the primary, Its bolted together with stainless steel screws.

And here with the secondary coil mounted on it!

This baby will weight a ton when it`s done, so I have to weld a aluminum base for it at some point... But there is still a lot to do;-)

Cheers, Daniel
