Hello,
I hope everyone is in good health and keeping safe. As you have probably guessed, this post is not A2 related. But as I've seen some great manufacturing talents on here, I thought I'd give this a go.
I had 2-mm-diameter 303 stainless steel (SS) rods press-fitted into C101 copper blocks as shown below:
The SS rods protrude from the copper block surface at equal lengths and I've had good results for my experiments. I'm now moving on to replacing the stainless-steel rods with graphite rods.
A vendor has supplied MCCA(?) grade rods to me which are 3 mm in diameter and cut to my desired length. I'm looking for ideas on how to affix these graphite rods to the C101 copper block. I don't think press-fitting them as I did with the 303 SS rods would work.
What is most desired from the connection between the graphite and copper is good electrical conductivity. As an added bonus, integrating a convenient way of replacing the graphite rods, when they break, would be beneficial.
Among the ideas that have been bounced around:
If anybody here has any thoughts, I would be glad to hear it. I'm not familiar with any machining forums so if somebody could point me to a good one to post this problem to, I would appreciate it as well.
Thanks.

Among the ideas that have been bounced around:
- Interference fit of the graphite rods within graphite sleeves, which themselves are press-fitted to the copper block.
- Use of mechanical clutch contraption (like that used on mechanical pencils) to hold the graphite rods in place.
