E5 TORQUE TUBE BUILD

(1/4) > >>

Helikid42:
I have tried building the E5 torque tube per manual but always ruin the radial bearings when slowly sliding them over the ca glue! The original tt was ruined due to radial bearings getting ca in them, then I purchased a second tt and it happened again! This will be my 3rd and final attempt and I sure hope anyone can help with this costly situation I am dealing with. I am almost certain it is the glue I am applying..super thin. Maybe I should use a thicker ca or 5min appoxy? Thanks to all on this topic.

curmudgeon:
If you want to continue using thin CA, I recommend you first place the radial bearings where you want then on the TT.  Then apply the thin CA to the TT close to the bearing one small drop at a time using a toothpick.  So apply the drop of thin CA directly to the tip of the toothpick, and then bring that drop of CA to the TT close to the bearing.  The CA will wick "underneath" the inner race of the bearing.  You do not need much CA to secure the bearings to the TT.

My method... measure & mark bearing placement w a sharpie... slide bearing on the TT close to placement.. apply Ca to placement area & rotate TT while using a tooth pick or small piece of paper make an even’ish layer of the CA... holding the TT vertical, slide the bearing down in the marked placement area SLOWLY making sure the CA doesn’t build up into the race of the bearing. Biggest thing is to just keep an eye on the CA so it doesn’t get in the bearing.. once it’s in place & the bearing is sticking.. just prop it up so any CA still flowning can not flow in the bearing.

"flowning"?

gwright:
As clay and others said, it only takes a TINY bit of ca.  I put a SMALL drop on, then use a piece of paper towel and rotate the tube, removing most of the ca but spreading whats left around the tube, then slip the bearing back down the 1/4 inch or so that I slid it out of the way.  Almost instantly sets off the ca, and there wasn't enough ca left on the tube to flow into the bearing
