I have a prescription for 375 mg naproxon ... slow release. I take one at about 2100 with a slice of toast and some water and it seems to tamp down the inflammation so I don't need one during the day.
I recently had a problem where I was attempting to fit two pieces around some fixed stuff. In hindsight I should have made a solid model of the fixed piece and then subtracted it from a solid and split the solid. In like manner it might be easier to cast a model of the gib then extract it from the lathe and figure out how to machine a matching one. YMMV. On the subject of sliding parts I've seen designs where one side is surface ground O6 and the other is bronze which is surface ground but also slotted cross-wise to hold lube and also reduce the contact area and the friction. Loading on ways is said to be about 250 psi which is why the thin modified delrin works so well. Glad you got your slide to work. I tend to be too impatient. ;-( Dave ------------------------------------------------------------------------------ Live Security Virtual Conference Exclusive live event will cover all the ways today's security and threat landscape has changed and how IT managers can respond.
