What You Need to Know About Glue | WOODWORKING BASICS

Plenty of brand-new woodworkers are surprised to learn that wood glue is often the most powerful method for connecting two parts of timber together. It can hold better than screws or nails, and in most cases the cement is actually stronger than the lumber it’s holding together. I’ve glued these boards together with lumber adhesive, and tells find where they violate. Here you can see the sphere that was glued up, still remains. It smashed along the speck of the grove. There are a lot of different types of adhesives, all with their own advantages. For specialty situations, I might use contact cement, or superglue, or red-hot glue, spraying adhesive, rubber cement, silicone, or construction adhesive.

But I’ll save those for a future video. In this video, I’m only going to discuss the cements I most commonly use and ever have on hand in my store. These are cements that work well for me, and that I’m confident to recommend to you. Yellow timber adhesive is the adhesive I use, and trust on almost every project. I use Tightbond II, it dries fairly quickly, but it’s slow enough to give me time to statu and adjust articles for assembly, and it’s sea resistant. To make it easier to employment, I pour it into a smaller bottle, this one is called a Glu-Bot. The primary welfare here is that it can pushing the cement out at any slant so you don’t have to hold it upside down. Wood glue is most effective on the face-grain or the edge-grain of a board and will create an incredibly tight bond.

Glue on the end-grain is a little different, I’ll talk more about that in a minuet. I like to make sure that every part of the joined surface is contained in cement. There’s a lot of ways you are able to spread it around evenly. You can use a disposable brush, or you could use one of the following options silicone basting brushes. They work out really well and you can usually find them at the dollar storage, in with the kitchen renders. But really, the most part about using these silicone brushings, is that it’s weirdly fulfilling to remove that dried-up cement. I don’t know why that is, but it’s kind of like that mood I get when I remove a splinter, and I merely need to examine it. For large surfaces, an age-old credit card or playing card works well to spread the adhesive, or even merely a scrap of cardboard.

But really I usually find the most convenient channel to spread adhesive, especially on the edges of boards, is simply to employment my finger. Wood glue laundries off readily in water, or just peels off once it’s dry. And that can be various kinds of filling very. It’s important to fix your boards together while they’re drying, to insure a strong bail. The destination with clamping, is to apply even pressing, all along the members of the commission. The more fixes you use, the very best. And you don’t need to stimulate them super close-fisted, a good way to judge is just tighten them until you interpret glue mashing out. I have no special technique for removing the extravagance glue I try to wipe off as much as I can while it’s still wets, use my thumb or a dry cloth. For timber cement to achieve it’s maximum persuasivenes, it needs about 24 hours of dry time. But that’s not how long you need to wait before keep moving with your project.

It is my finding that I can remove the fixes in about an hour, as long I’m not subjecting the joint to any stress. And if, if I’m feeling additional frisky, a half hour is typically fine. I can’t often wipe off all the extravagance adhesive, so I simply sand it off formerly it’s dry. The important thing is to make sure that you get it off any areas that will be visible. Doubled check the timber by wiping some mineral feelings on it. It will spotlight any areas that you missed so you can sand them off. It’s also worth pointing out, that fastening is not ever necessary on certain small-scale or decorative jobs. It’s fine to glue small-time articles in place by merely preparing them in place and telling them dry. This is especially useful for artwork projects such as collages, that won’t receive any stress and there’s really no practical way to fasten them anyway.

A technique I like expending a lot, especially on example projects, lockers and such, is to cement the boards together and then tacking them into residence with a brad or a pin nailer. The nails alone aren’t really strong enough to hold the employment pieces together, but they act as clamps. So once I glue and tack the members of the commission together, I can instantly move on with my assembly, rather than having to wait an hour. Of course there is one major impediment, the nails will leave visible flaws. This isn’t a problem if the joint is a part of the project that won’t present, or if the project “re gonna be all” painted. Nonetheless, if it’s on a fine segment that you wish to stain or finish, it will be nearly impossible to fill those defects and pair the colour of the timber perfectly.

Gluing on the end-grain of members of the board is not stronger and stronger but it can be acceptable. Thoughts the particle of timber like these straws, the end-grain is hollow, that’s the direction that the tree grows and how sea and nutrients pass up the trunk. So when you apply glue to that end-grain, a lot it gets soaked up , not leaving much for bonding. This is mostly a problem on projects that are going to be subjected to a lot of stress or move. For small decorative projects, it’s usually fine tell for caskets, or mitered areas on video frames.

There are a couple of techniques you can use to improve the strength of end-grain glue-ups. The first is to make up a sizing, for the end-grain. Sort of a preconditioner. Represent up a mix of half glue and half ocean, and brush it on. The thinned cement fills in those pores readily. Let it dehydrate for a while and then adhesive together your slice like normal with full-strength cement. Another method, the one I usually use, is just to pressure full-strength glue into the holes of the end-grain. Just smoosh it in, you’ll read and feel it being absorbed. Then just let it dry a few minuets and cement it up as normal. If this is going to be for a chair or table, something that’s going to be subjected to pressure, I would reinforce this joint with some sort of a mechanical fastening, like a fucking. The strongest method would be to add a couple of pocket fuckings. Not surprisingly wood adhesive drives awesome on, well, timber, but not so well on anything else.

And sometimes you need to join wood to other fabrics, articulate metal, or plastic, or glass. In most of these cases, I like to use epoxy. I find the 5 hour epoxy operates great for virtually all my requirements. They always come in two parts, that you need to mix together. Mix it together really well, and dab it on the duties you want to join, there’s no is a requirement to fasten. So why not only utilize epoxy for everything, instead of even riling with lumber cement? Well for one thing, it’s more expensive, but it’s also messier and a little bit more difficult to use, having to mix it up every time and you can’t really sand it down very easily.

And if you’re connecting two parts of timber together, it might not be as strong as lumber glue. And since it’s not water-based, clean up is kind of a sorenes. If there used to be a single cement I would consider using for everything, it might just be be Weldbond. I’ve only recently started use it, and I find myself using it more and more, it’s got a lot going for it. It seems to bond just about anything, just like it mentions. I’ve applied it for gluing together painted committees, something that wood doesn’t do well. I’ve utilized it for glass, and ceramics, terracotta, metal, plastic. Another great boast of Weldbond, is that it dehydrates clear and it just doesn’t seem to be as messy as lumber adhesive.
