McMaster has them and ships fast but they are $45 instead of around 10 on amazon

SDP-SI doesnt carry the right sizes

Shipping speed is of the most importance but preferably with a reasonable price

Thanks

Are you coming to Lone Star? If you are, and you don't need them till LSR, buy some 1/4" to 1/4" or 8mm to 6mm couplings and ship them to ME. I'll drill and ream the wrong side to the right diameter on the lathe next week and hand deliver them to you Friday morning.
