For my 2nd cab I decided to say 'screw Happ and Betson/Imperial' and I purchased a brand new 3' Wico with a plain white resin ball. I gave up and left it that way since I was about to start work on a 2nd cab. I did this and it got rid of some of the vibration but a far cry from perfect. So then someone told me to get rid of the polycarbonate translucent ball and replace it with a plain white or black solid resin ball because they have more density (heavier) and are usually more true then the polycarbonate translucent balls. It didn't click like the Happ model but it made the famous brrruuummmbbr vibration when playing golf games. In fact, I was crowing about how smooth it was on these very forums way back when. I then bought a brand new 3' Betson/Imperial with a translucent green ball.For a while it was nice and quiet and I loved it. I sent the berings and rollers back and got replacements but they didn't help.

I had bought a brand new 3' TB from Happ for my first cab. One of these days I'll actually finish all my TB CPs, and my cab with changable CPs. Doing the presure roll on them didn't result in a noticable change.Īnd even with the burring, my first happs had a longer roll then the betson (barely) or wico (a lot). OTOH, the two I built (mostly from parts from BobRoberts) started really bad, worse than my happs built one, but improved mostly after lightening the six case screws a little. I could feel a minute bump/bend in one of the rollers when I first did this: I guess the pushing and rolling speeded up the roller's wear a little, and wore out the bump. If you try this, do NOT put your whole weight on it about 10-15 lbs presure should do, and keep moving the ball for 1-2 minutes. My kensington TB instructions said to do this to help break in the bearings (& rollers). My happs 3' TBs started out with the burring, but has quited down a lot over time.įWIW, my original only got better after I 'gently but firmly' constantly pressed down on the ball while rolling it in a circle.
