In the construction of a FTN.5/4.5/4/3, etc is it recommended to anneal the PA6-CF? It seems it looses some of it’s impact resistance and flex but temperature resistance increases and also becomes stiffer and slightly more brittle. I’m assuming it’s recommended but just wanted to verify. Thanks!

Wanted to ask you - why the printed threads on your stuff is always not 1/2x28? Is that something that impacts the performance?
Also, do you think printing a thread adapter from 1/2x28 to the correct thread for your stuff is a viable option or it should be a non-printed metal adapter?

im new to this side of the community. where can one purchase a thread apapter ? specifically for the ftn5 rimfire device ? maybe amazon ?
per the readme…
“Assembly - Screw in a 1/2x28 to 3/4x16 thread adapter (you can epoxy it in if you want)”

thanks for the response.
I have a question about the FTN.5 and the printed shell, is a 14" barrel safe with the printed shell?

I’ll probably try it out since the new flow through can prints way easier for me. Had to use the tight breek because the original one had too much play and caused bore misalignment. So far so good now.
any reports on pps-cf printed at temps >350 ?

cool… once i get my qidi plus 4 gears cleaned, i may try to print something in pps-cf.
i may also try plain pps…
Yes, the greatly improved heat tolerance far outweighs the small loss of impact strength. And even annealed, the moisture conditioned impact strength of PA6-CF will be higher than most other materials.
Awesome, thanks!
I personally hardly ever anneal anything anymore. Sometimes I will anneal small functional parts, but more than none I just allow them to absorb moisture so that they get their elasticity. I have done both ways on FTN’s and they stand up very similarly. You will be fine by not annealing a FTN.
Yeah lol I never anneal either. Too lazy, my NYLAUG, STG, DB9, and DEAR22 have been fine for awhile.
I personally don’t think it makes enough difference in our area.
