Thanks again Paul. Was really impressed with selection and pricing. Lots of stuff I have looked for over the years and McMaster has some but not all and dedicated to this type of hardware. Was looking for an M7 x 20mm nylon tip set screw a while back and there it was...and pretty cheap too, considering you can purchase individuals instead of a box for >$100! Admired your indexing setup from before...really versatile and well thought out! ~PJ
