I think you are probably right - 2 pieces - there were just 4 pieces in the folder when I clicked ‘download all files’, maybe the other two are old files. That helps the price a lot.
I believe that polyamide = nylon which sounds good
Those prices work for me, especially if we can hit 10 orders. I think that so far we have just 3 orders I think, so we either need 7 more people, or need to take a risk and order 10 between us, which we could then sell on in the future? Maybe in combination with the rods etc to make a complete kit for modding a Bosch router.
Thanks again for getting this figured out and moving
