Hello everyone. I have been lurking out here for a few months enjoyingall the discussion. Love the Piet but after much thought have started tobuild a Hatz. My question is which kind of glue do you guys like best forrib construction?My rib jig is built with clamps that can apply considerable pressure tothe joints while drying. I hope not to have to leave the ribs in the jig toolong as I will try to build them all during a two week vacation. Also, withclamps to apply pressure to the joints I think I can forget about usingnails, am I right?-----Original Message-----

Hi Guys, Am building a long-fuse Piet and using T-88. This glue really does not needhigh pressure clamps, and on a flat surface does not need nails or clamps of anykind. Some folks worry about a slight surface stickiness when extremely hot,after fully curing, as inside the wing on a hot day.. In speaking with themanufacturer and a couple of old time builders who use T-88, this is a side effectof the non-brittle long life of this product. For your own peace of mind, wouldstrongly suggest that you glue up 3-4 pieces with different intersecting faces,let fully cure, set out in the hot sun and then self test them to destruction.Aswith all of these resin type products, it is extraordinarily important that mixingratios be properly observed, and that the mixing is thorough.Warren________________________________________________________________________________

I used T-88 to build my all-wood Minimax. Its structure and loads are similiarto the Piet. I've flown many hours in the MiniMax. Some of those hours have beenin rough air when I would rather have been on the ground but I've never hada joint failure. I think the T-88 instructions call for only light pressure whenglueing so you won't need those clamps for the ribs if you use T-88. Staplesmay be better.Safe flying,Leo --On Tue, 13 Oct 1998 07:26:33 Warren D. Shoun wrote:>Hi Guys,> Am building a long-fuse Piet and using T-88.

Hey, guys, I use Titebond II from the hardware store. It was recommendedat Oshkosh in one of the building sessions. >>> "David B.

Hey Scott,The rib jig I have in mind will only handle one rib at a time. This will besomewhat of a hinderance as I hope to build the ribs in a matter of weeks(as opposed to months). Have you seen a Jig for multiple ribs?T88 looks good to me so far, seems like it must be a fairly standardtwo part epoxy like I have used for years in RC model construction.It should be pretty easy to work with.-----Original Message-----
