I was quite fortunate, Evan, in that I was working over the granite countertop of my kitchen island. I heard them hit and knew immediately (after issuing a few expletives). I'm lucky they didn't go bouncing and then rolling onto the floor. I honestly wasn't expecting them to come out at all.
In sum, the watchword to use when adjusting the endplay of the main shaft is "touchy" - it's a very small arc of the allen wrench between too tight to turn and ball bearings bouncing all over the place Steve Wedge, W1ES/4 To be is to do - Socrates To do is to be - Plato Do be do be do. - Sinatra All my computers have my signature with various pearls of wisdom appended thereto.

Steve, Not that you would ever need to do that operation again, but what I have done when I'm concerned about dropping ball bearings or other small parts is to use some blue "painter's tape" and fold it around on itself so that it is like double sided tape. Then I put it in places where parts are likely to drop. I did this as a precaution when removing one of the ball bearings from an L4B bandswitch which is one beefy, hard to turn switch with the original knob. Removing one of the two ball bearings did the trick. And yes, the tape caught the falling ball, hi hi. Amplifier HV doesn't seem to get along with metal balls where they don't belong, hi hi. Don't forget the Drake nets today and Tuesday evening. 73, Evan, K9SQG -----Original Message----- From: Steve Wedge <w1es1...@earthlink.net> To: Drake List <drakelist@zerobeat.net> Sent: Sun, Oct 23, 2011 8:46 am Subject: [Drakelist] Watch those ball bearings! Working on cleaning and refurbishing R-4B s/n 15533B, I removed the PTO and started to clean and re-lube the bearings. After some 3-in-1 oil and Rem Oil in all the usual places, it was still a little stiff, so I removed the cover and started backing off the tension adjustment. I now know that it doesn't take much tension removal to make the ball bearings start dropping onto and rolling about the table! It was a bit of a bear getting them all back in, but about 20 minutes later - mission accomplished. It's tuning smoother but I'm still feeling some roughness when turning it by the shaft. I suspect the action will be easier with that big knob back on it. Watch the bearings when adjusting tension! The R-4B has been washed on the top only, rinsed with distilled water, air-blasted and is now sitting in its sauna in the kitchen, where I'm keeping the temp at around 140 to help with drying it out. It will get re-capped over the coming week. 73, Steve Wedge, W1ES/4 To be is to do - Socrates To do is to be - Plato Do be do be do. - Sinatra All my computers have my signature with various pearls of wisdom appended thereto. _______________________________________________ Drakelist mailing list Drakelist@zerobeat.net http://mailman.zerobeat.net/mailman/listinfo/drakelist
