I am not familiary with the term Hot Stuff, at least, it is probably not availably in Denmark. Could anyone give me a hint, what "Hot Stuff" is?? Is it some kind of 5 sec. glue??

It is a brand name for a Cyanoacrylate (CA) glue. Hot Stuff, Jet, Zap, Super Glue, etc are all brand names for the stuff in the US, at least. Date: Fri, 12 Feb 1999 16:15:06 -0500 From: "Thomas W.

It the same family as what we have available in most stores called "Crazy Glue" for surfaces that fit very closely together, a drop or 2, put the pieces together, and in a few seconds the bond is complete. The thicker consistency of the Hot Stuff will fill small voids. There is an accelerator for the Hot Stuff, it comes in a small spray (finger up down type pump) bottle. The Hot Stuff sets slowly when there isn't a tight fit, a quick spray, and its solid. Recommend getting the accelerator. Both are in Spruce's catalog I think, used to be anyhow.

We normally get it at a hobby store which sells model airplanes and such. There are a couple thickness variations and most folks like the thicker version for our application. Hope that helps.

Here is a subject on which I have a lot of experience, all borne of the gasket industry (long time ago) and the Radio Control hobby. CA glue, including Hot Stuff (also my personal favorite) comes in a variety of viscositys, these days. The way it was explained to me about how this stuff works, is like this: It is really a two-part glue, kinda like epoxy, but the two parts are prevented from "going off" by a slightly acidic inhibitor. When the glue spreads out very thin, in a tight-fitting space, the normal amount of water condensed on the surface of most things is sufficient to lower the ph just enough for the stuff to go off. Extremely dry conditions are not good. It sometimes helps to breathe lightly on the parts, before bonding. The accelerator is nothing more than a base. Baking soda will work just fine. There are a couple of important tips for using it, though. It works best to breath on, then dust one surface, and apply the glue to the other one. If you can use pins or guides of some sort to bring the two parts into contact with each other in exactly the correct orientation, it is a good idea, since the stuff will go off so quickly with the introduction of the baking soda. The other way is to use the baking soda as a filler, or even as a fillet. Drip the glue onto the joint, and it will go off very fast, and quite exothermically, including a little puff of smoke. Don't get that smoke in your eyes! The result is like concrete! Use poly plastic bags over your fingers when you must handle the parts, close to the glue line, because this stuff sticks to skin better than almost anything else, and it does it before you can say "oh sh..." The more you play around with it, the more great ideas you will get for its use. Example: You can slap together a fancy drilling or sawing jig for your drill press or band saw with lots of little wooden blocks and a bottle of Hot Stuff, by just gluing them to the table. Just knock them off with a hammer, afterwards. A million uses for temporary holding of stuff during layup sequences, and no waiting. Try the baking soda thing. It expands the capability a lot! Good building. --Howard Rogers Date: Fri, 12 Feb 1999 21:50:53 -0500 From: "L. Wayne Hicks" Subject: COZY: Hot Stuff -- buy from ACS or 7-11? The plans say Hot Stuff, but should we buy the stuff from ACS or is the stuff at the 7-11 checkout counter good enough? (Let me guess...7-11 variety is too viscous, right?) In ACS catalog, it looks like you buy a larger quantity than needed for Chapter 11. Is this Hot Stuff used again in later chapters?

The Hot Stuff has a shelf life of maybe 6 months, it goes a long way, I wouldn't buy more than 2 oz. at one time. Try to get fresh stock. I have had to special order from local hobby shop, who was happy to order, but wouldn't stock. Have had no problems with shelf life several orders from Spruce. Date: Sat, 13 Feb 1999 11:34:19 -0500 From: Bill Theeringer Subject: COZY: Hot stuff glue.. I have been using the thicker hot stuff for 8 years in the manufacture of the cabin heaters and it sure does have a shelf life. I found I can make it last almost indefinitely by storing it in the freezer. Even when it is very cold it flows nicely. One caution, store the accelerator away from the glue. They can sit on the same shelf 6 inches from each other and the glue will set up. I keep the accelerator in a large empty plastic butter tub. I buy mine from Satellite City in Simi Valley, CA. They have an informative 8 page catalog on their hot stuff products and can be reached at 805-522-0062 or fax 527-9114.

Here is a great source for Hot Stuff, as well as a host of other great stuff.

This is true, the shelf life is short, but there is a "sort of" workaround. If you store the adhesive in the freezer (no, it won't freeze), the shelf life is almost indefinite, but there is a catch (of course). Once you open it, you had best leave it at room temp. In fact, let it come up to room temp before that first opening. Once open, if you attempt to take it in and out of the cold, the cooling and warming cycle will cause condensation, which will ruin it shortly. It's best to buy the stuff in several small containers, rather than a large container, unless you forsee an upcoming project that will use a LOT of it. If you keep them in the freezer, there is no reason to worry about buying a bunch at once. I read about this in RCM (Radio Controled Modeler magazine), have done it many times, and it works as advertised. --Howard Rogers From: Militch@aol.com Date: Thu, 18 Feb 1999 14:22:19 EST Subject: COZY: Paper adhesive I know I saw this answered in the archives once, but I can't locate the reference. What is the best way to glue paper or vellum templates to foam when preparing to cut out parts? I used ordinary Elmers Glue in just a few spots. That stuff is tough and it sticks to Last a Foam better than micro. It took longer to sand the little spots off than it did to do the layup - clearly not a good approach. The discussion identified a spray on adhesive that didn't shrink the paper and could be cleaned off with MEK or some other similar solvent.

That stuff is tough and it sticks to Last a Foam better than >micro. I think based on your location (ch4 and 5) you are working on bulkheads. I'd not glue the paper to foam, but rather tape it. When you are gluing templates to formica/aluminium/plywood for making hotwire templates, I use the 3M 77 spray adhesive, available at most drug and hardware stores. Chapter 4 you use a lot of templates, then suddenly you hardly use any, it is a weird transition. I remember that.

I used ordinary Elmers Glue in just a few >spots. I sure wouldn't glue templates to foam before doing a layup. You're liable to interfere with the epoxy/micro to foam bond. Repeat from archive: For bulkheads and such, I laid up foam pieces a bit larger than needed, then after cure I stuck the templates/drawings on the panel (peel ply still in place) with double-sided 3M tape. You can find the tape in hardware store where the window sealing films are. I then cut slightly outside the lines (about 1/8") on band saw and sanded the edges to the line. Worked for me.

What is the best way to glue paper or vellum templates to foam I traced all of my prints on the bulkheads by laying sheets of carbon paper that I bought really cheap at Staples. Then I taped the plans on top of that and I used a burnishing tool from my dry-transfer decal kit. I am very happy with the results. Although I have nothing to compare this method to since I have never done it before. This also allowed me to make corrections like making the bottom of the instrument into a flat line. before cutting. J.A.Millington #706
