[3dem] Gatan clipring tool

[Eric Hanssen]

HI Reinhard, 
Yes we still have the original tools, instead of one I have two. It is very rare to get two tools for $0 for Gatan product ...

I didn’t need the workshop for that, remove the broken wing with a msall pair of forceps, file with fine (1000) sand paper, "et voila"
I am not sure how much longer it will hold but so far so good. The clip rings do not seem to wear out faster than with the standard holder.

Dear Terje, Eric and Reinhard,

The recent thread on the 3dem re: the Gatan 70 degree clipring tool has caught my attention, as I understand your concern with the tool's current cost.
In the midst of repairing TEM holders, I will attempt to reverse-engineer these tools in hopes to determine how best to manufacture these on my own, therefore establishing a lower cost.

**I wanted to let you know that I will try to help you with this situation. However, at this time I do not wish to make my plans public knowledge.
Thank you.

Respectfully,

    This sounds like a nice solution, indeed. 
    Yes, I had taken apart the GATAN tool once (our broken tool), but I did not get the idea to make two tools ... 
    Thanks, Eric. 
    Do you provide fotos of your tools (which you had got made in your workshop, I assume?)? 
    Or do you still use the original parts from the Gatan tool, taken apart? That's easy.

    this sounds promising.  Thank you for this valuable hint. 
    kind regards, 
    Reinhard
