When you go to glue I to or the first time, if you've got a heat gun, follow PTWoody's advice and don't bother with the glue gun. If (like me) you don't own a heat gun to directly heat the glue stick, you'll probably find the speed at which the melted glue comes out of the gun isn't really fast enough to get a nice even spread over the end of the handle and slide it into the paddle shaft before it starts to stiffen. Easiest way I've found is to apply a good thick coating around just the bottom half of the part of the paddle that fits inside the shaft (don't worry if it gets a big uneven or starts to stiffen). Next, grab a hairdryer and heat the glue evenly by rotating the handle until the glue softens completely and spreads out to a fairly even coat. Then slide the handle into the shaft and line it up (the residual heat in the handle from the hairdryer slows the cooling process and give you enough time to get the alignment just right), the glue around the bottom of the handle will spread up the handle as you push it into the shaft, allowing a good strong bond over the maximum possible area to hold the handle in place.
Hope this helps a little!
A couple of other helpful tips to get a good bond and a nice clean finish.
Tape both components (shaft & handle).....at the point where you don't want the glue to go beyond.
As well as heating the handle covered with glue, also heat the shaft.....this will ensure a good bond to shaft.
If shaft is cold the glue will harden too quickly and will not bond adequately.
When assembling rotate the handle and also pull it in and out a couple of times to get a good spread of glue.
Once handle is in place and glue has cooled enough so handle will not rotate, reheat the exposed bead of glue and flatten it with a wet finger.....then remove tape while glue is still soft....this should leave a fine glue bead at the joint.
Lightly heat remaining glue bead and smooth off with a wet finger.
If you do it right you will end up with a really nice clean finish and have a perfect seal.
Sounds like a lot of stuffing around but it is really easy
