Hi all, I'm trying to put together some homemade syringe couplers following the published instructions from the Caffrey group. I'm having a bit of trouble with this part:
"The stainless steel ferrule of the second needle is removed and placed on the free end of the coupling needle such that the double thumb nut is held symmetrically between the two steel ferrules" Has anyone done this, and if so, how did you remove the stainless steel ferrule from the second needle in order to place it over the first? The stainless steel ferrule appears to be firmly attached and I'm having trouble removing it. Thanks, Thomas Cleveland
