a question....The GN-1 plans don't specifically call for "corner blocks" where longeronsmeet the uprights and diagonals. By corner blocks I mean small trianglepieces of spruce about 1.5 x 1.5" on either side of the uprights to increaseglue surface area. My dad is insisting that I should include corner blockssince his Fisher Celebrity plans called for them. I've been looking at lotsof pictures of Piet frames on the table and have yet to see any with cornerblocks. Are gussets on both sides enough to strengthen the joint so thatcorner blocks aren't used??.... esp. in a GN-1 where the plywood side goesall the way to the tail post??What's the consensusDJ VeghMesa, AZGN-1 Builderwww.raptoronline.comN74DV________________________________________________________________________________

On the GN-1 Don't Do It!No, really, the additional corner blocks interfere with the bolts for eachlanding gear attach point bracket, wing attach point, and the bolts for theengine mount brackets. Notice that these brackets have bolts runningthrough the logerons vertically. Corner blocks are in the way. This meansyou have to either do without the additional bolts (not a good option) orweld small ears on each side to run the bolts through (also not a goodoption - but thats what i did)The way it is designed should be just fine, I don't think it's neceassary toadd them (ala the Fisher). My 2 cents - Email me off list if you need moreinfo.Bert----- Original Message -----

corner blocks are not necessary, the gusset is there to increase the surfacearea for glueing and is quite enough.----- Original Message -----

Subject: Re: Pietenpol-List: fuselage sides - corner blocks?HI DJ,Corner blocks are not necessary. The gussets serve the same purpose and are lighter. No Piets have come apart structurally; they are overbuilt, you don't need to add more weight.Cheers, JimNX499JB________________________________________________________________________________
