				Dear Listers,
 
 When constructing the rudder halves together, it is advised to use Proseal 
 or the tank sealant to initially join the aft part of both skins.
 
 Could you also use West's systems epoxy to do the job?  Seems like you just 
 want something that will provide some initial holding power.
 
 Would appreciate some advise.
 
 Thanks in advance,
 
 John Brunke

				You want to use a product that remains flexible. Expoxy is quite brittle 
 and will probably crack and may cause problems down the road. Use what 
 Van's recommends they have the best know-how.

				I used West Epoxy system to glue the halves together.  I asked Van's and it
 does not matter what you use.  Use nothing  if you like it just makes it
 easier to create a bond along the length of the rudder.  All of those rivets
 will hold together just fine.  As for cracking down the road,  not an issue.

				Folks have successfully used epoxy to hold the two halves together for
 riveting. In the end, the rivets are what holds the rudder together.
 However, I do know one local builder who used epoxy and found it to be
 less than a completely comfortable choice. As he would rivet he would
 hear loud cracks as the in-flexible epoxy let loose.
 
 He felt that due to that in-flexibility the rudder wasn't held as secure
 during the riveting process. That being said, his rudder came out straight
 as an arrow.
 
 I've discovered that not everyone has noticed you can purchase _small_
 quantities of Proseal from Van's. The little 2.5 ounce amount would
 easily be enough (more than enough) for the rudder operation. I try and
 keep a couple of the 2.5oz Proseal packages in my fridge waiting various
 small sealing tasks.
