I did it on the Nike kit because I wanted harder wood when forming the diamond taper.<br />I wouldn't recommend breaking the joint, you might end up with a bigger fix than you started with. You could use some CA glue over the joint, that will strengthen it and would be easy to sand smooth. Once the root edge is glued on the body tube it should be strong enough.<br />I don't normally paper fins. Papering would be difficult on this model given the fin shape.Chris Michielssenhttps://www.blogger.com/profile/06907925631001358372noreply@blogger.comtag:blogger.com,1999:blog-3612012025300219489.post-32431369485450491172017-03-23T00:48:10.368-04:002017-03-23T00:48:10.368-04:00Smart!

The glued joint was week and two of the three fins wobbled at the seam. Still they were attached, but wiggling the fins a tiny bit showed the weak joint.<br /><br />Should I break the joint and re-glue, form new fins or harden the fins with paper? Any preference? Or so long as the wood grain is aligned properly to the rocket tube, all should be well.<br /><br />Inquiring minds...Scotthttps://www.blogger.com/profile/00317086474676888675noreply@blogger.com
