How much T-88 epoxy should I order for a Dakota Hawk?
Somewhere between 'not enough' and 'too much'.
Seriously, though, are you asking how much you should plan on buying for the whole project, or asking for application techniques for each joint?
Depends on how hungry it is. North Dakota hawks tend to eat more than their southern brothers:roll:
Sorry. I just couldn't resist. It's been one of those days..............
I would ask how much can you use in a year. Or how much building will you be doing in a year. Why purchase this t88 to have it set on the shelf for who knows how many years before you use it. Buy what you plan to use in a few months. Its not like there will be a shortage of this in the future.
Budget for 3 quarts. My UL took a little over 2 quarts, and I expect my tiger moth to eat close to 3 or a little over. You can probably put the fuse together with one quart, maybe the tail too....depending on how many laminations you have and if you are building ribs at the same time. I have about a dozen ribs built and the basic fuse together (no tail) and have used about 1/2 quart. By the time I finish the spar carry thrus and the rest of the ply bits on the fuse I expect to be about 1/4-1/3 into the next quart. I am not stingy with glue. I would rather wipe off/sand off the squeeze out than have a starved joint. I would just buy a quart to start. That should get you through the wings or either the fuse. If you are still building when the bottles get close to the bottom...... then proudly (and rightly so) order some more glue to keep the project going!!!!
I was mostly wondering if buying a pint at a time would be enough, or if buying a quart would only get me 10 ribs. Looks like I will order a quart of the stuff tonight.
BTW, Brian Clayton, I love your basic flying rules.
and some cheap little plastic cups from the dollar store, popsicle sticks for mixing and harbor freight sells big bags of acid brushes dirt cheap that are great for putting the glue on
Just a note om the T-88. I purchased a kit from Aircraft Spruce and planned to only use it for my project and have used it for all sorts of things for home and work as well. Must figure out a way to work that into the estimate as well. Love the T-88 myself.
When I had a wood project, I found myself using T88 for about every household maintenance problem that came up. Seems like I even filled a hole in something, then drilled and tapped it for a machine screw. The wife hated it because I kept gluing every broken thing she brought me.....kept her from buying new "stuff".
I also got into bonding nutplates onto wood for nonstructural things like access plates. The T88 bonds to the wood and forms a solid attachment in the rivet holes. I usually allowed the glue to fill the hole and drove a cemented nail in to hold them in place.
Make sure your mixing cups aren't waxed. Eat lots of popsicles.....
Whenever I go to a fast food eatery that has condiments in bulk I try to fill my pocket with the little plastic cups they put out.
Work great for mixing up small portions.
Keep in mind that T-88 is available locally at most woodworking stores. Sure you can "order" it a little cheaper, but if you run short a quick drive to Woodcrafters or Rockler will have you back in business without waiting several days for a delivery.
I think I saw it on amazon for a little less too
I'm just a tightwad, I guess. I use a tuna can that's been cleaned out and a 1/2" wide piece of 1.5MM ply about 5" long to do the mixing (wipe off the "paddle" when done), and apply the T-88 with small paint brushes, cleaning them out with a small amount of MEK that I keep in a closed container. OK I do splurge and use fresh MEK about every 6 or 8 brush cleanings. Reduce/Reuse/Recycle.....I'm so "green" Nah....just cheap!
I buy the large package of condiment containers from Wal-Mart and use the covers for small batches of epoxy. I get the tongue depressors from their craft section too.
The little plastic cups from fruit cups work great. They are generally smooth enough inside that squeezing them a bit after the leftover epoxy has tried lets you pop out the dried excess and reuse the cup.
