Yeah looks like your going to need some good wheels on that! Looks like a lot of money, and hard work, looks good I had that idea also awhile back when i was trying to do my 2ft SGTC, a rise/lower base..but I decided not to go forth on doing so. Nice to see you have though, Keep up the good work

It seems like ACME threads would have been better for the lifting system, but finding nuts and bolts with acme threads wouldn't exactly be an easy task.

Daniel, awesome work as usual, but a step up again as a true artist does! A question about the stainless steel screws you are using. I know that stainless is not ferrous but do you think that they will interfere with the magnetic field at all?

Hi Coronafix,
I have no idea if the stainless steel screws will make some interference with the magnetic field, but if it does, I doubt it will be much:-) But time will tell...
I'm currently making the primary holders, so maybe I will wind the primary this weekend:-) Then I can test if any of the stainless steel screws get hot...

If you don't mind answering, what is the expected total cost of such a system? And what are the range insulators you and finn have used from? again, impressive.

Well, at the moment I don't have a clue about what the total cost will be, but it ain't free, I can tell you that much:-) I think the mechanical parts will cost me around 1700$ when I'm done, and then I need some stepper motors, drivers, power supply and a new MMC...
I'm just glad I don't have to pay anybody to have the parts machined, then the price would be sky high:-) In the shop I work at, we take just around 100$/hour... And this is really cheap in Denmark for mechanical jobs... I worked on the primary coil for 8 hours today, just to make the holders for the primary coil...
The “insulators†we use is actually sewer pipes made out of PVC, they look amazing!!!

Wow, looking good, really taking it to another level with this one. The engineering, machining everything top notch. Congrats!
Will be looking for updates on this one.
BTW: Something I don't quite get, how will you wind that wire onto the secondary coil-form? Will you make "holes" through the ribs to pass the wire through?

Hi All,
This weekend I had Finn in the shop to help me with the soldering on the primary coil. This is a true helix coil, and the soldering was a pain in the ***
If I were to make such a primary again, I would solder the last 3 turns instead of all 10...
Here are some pictures for your eyes:
Unfortunately we don't have more Argon in the shop, so I have to wait until January to weld the base for the coil...
