Graphite in the ball pocket will definitely cause the ball to stick in the pocket. Ask me how I know... Whether there is any apparent flash or not, burnishing the ball pocket with a toothpick is part

Hi all, Unfortunately, Frank Glatlz no longer makes the rotary couplers that we sold for a few years. Volume was pretty low on those and continuing to offer those just can’t be financially

Hi all, A few years back, some nice person sent out a few million spam emails spoofing an email address from the sergentengineering.com domain. Those emails didn’t really come from me or even my

SMMW’s recently-released coupler boxes have been well-received so I thought a quick reminder is appropriate to reach those who may not know about ‘em. Visit my web page for more info, then

I sent an email to info at sergentIengeniering dot com and got a timely and informative reply from Frank Sergent the next day.

Hi I’ve recently learned of Sergent’s existence and have been trying to reach the company for more details. Lacking an email reply to the website address I used, I began to look around to see

Dale: Thank' for your update and research. The use of the Kadee the 714 coupler box seems very promising. I will try it soon. Mark Lewis Stony Point, NC
