Adhesives

Recommended Posts

I've got adhesives by the number

Adhesives by the score

Every time I turn around

I swear I find some more!

Actually this is a two part question, adhesives and frame clamps. I make most of my frames from cedar fence stakes. They are very rough, often cupped, uneven thickness, etc. I like the looks of the frames because they are rustic. In spite of of problems with the materials I try to make the frames as accurately as possible. I have old Craftsman corner clamps, Pony strap clamps as well as H/F strap clamps. Of the three I like the H/F straps the best. My dilemma is the adhesive. It take a fair bit of time to get the straps positioned accurately. The adhesive needs to remain open until the straps or clamps can be tightened. There has been discussion on clamps previously but not on adhesives that I know of. Need some advice on adhesives. Currently I glue the best I can then pop some staples in the corners from the back. I also have thin, medium and gap filling ca, tube of Loctite cement, JB Weld and more. What to use?

Les, I use Pony strap clamp for my frames, but I think any brand strap clamps should do the job.the most important factor in frame making is making precise 45° cuts and just as important, is cutting each pair of sides exactly the same length. If one side is longer, even a fraction of an inch, the frame will not be square. As for glues that you show, I would use the Titebond, but any of the white Or yellow glues will work without any problems.

I don’t bother reinforcing the corners as I glue the art piece into the frame.

You can make the frames by using tape at the corners to hold them together before putting on the clamps.  This is a trick used in box making to hold the corners together.  Lay the outside edge of one of the frame members on the sticky side of a piece of tape, with some of the tape extending out.  Then put the next one against it, then tape to the rest of the frame in the same manner.  Leave the last piece of tape sticking out.  Put the glue on the joints and kind of roll up the frame so the joints are together.  This will hold the frame together while you get the clamps on.  Or just put staples in the back or nails into the joint to hold it without clamping.  Hope you can make sense of this.

Well hell lets add one more to the collection, I prefer titebond translucent for woodworking and frames.

Add saw dust where needed to fill gaps after filling with the translucent glue

My wife gave me clear chalkboard glue since she is a teacher and I use that to mend mistakes with. Have had an error yet which requires sawdust and would like to keep it that way!

I guess I'll throw my 2 cents in here. Someone suggested 30 minute epoxy and for the project you described I think that is a solid suggestion. Wood glue works best when the faces meet well. If your stock is 'off' and gaps are created IMHO epoxy will fill gaps and hold better that poly glues. And the nice thing is they can be tinted to match your stock.

Then the clamping. I like band clamps and use one but for difficult work I use this crazy system. I've made these little corner jigs. The bottom (the part that comes in contact with your frame) has 100g sand paper attached with DST. Prevents slippage in clamping. Just look at the pic. The jigs are clamped to the frame members first and then a F style clamp pulls the corner together. This lets you focus on each joint individually. I usually just clamp half the project, let the glue set up and then do the other corners.

I've used a lot of different glues to glue the clock to the base.. and one day while shopping at Menards I ran across the tite bond translucent glue.. I've been using it exclusively for a couple years now and really like it.. That said.. I've never had any issues with any other wood glues in the past.. I've used a lot of different name brands..

I make small boxes of cedar  or ash.  I cut the corners of the four sides on my miter saw and apply white Elmer's glue and hold them together with rubber bands.  It sets up fast though.  On larger projects, I still use Elmer's white glue and tape the corners together before applying clamps.  This glue dries clear .

Good looking clamping system you use.

Les, I use PVA, almost any marked "for wood". Selly's

or Parfix

Almost all PVA glues are stronger than the timber.
Butt  joints or end grain can be a problem, but only in where stress is involved.
When making frames I usually just staple across the joint on the back and then clamp down flat to a board. If mitres are cut correctly this will give a serviceable and sufficient bond.
Sometimes I will use a feather across the cnr, more for decoration, but it adds strength.

About 4 minutes into the video Nick Engler talks about gluing end grain to end grain in a butt joint. I have done this using this method, and I can't break them apart. I suppose I could clamp one end in a vise and beat it with a 4lb hammer or use a pry bar on it, but I don't see the point. An old retired Army guy mentioned this to me several years ago, and I kept meaning to try it but never did until recently.

I have used this technique, on frames eg mitres, but would never use it on furniture without a physical support, such as a joint, dowels etc.

When making frames accuracy counts.  This applies to the angle and the lengths.  Wood glue is not designed to fill gaps so the tighter the corners the better.  I stack cut my pieces on the miter saw so they are exactly the same size.  For clamping I use a Merel clamp.  I also use "V" nails in addition to the wood glue.  The beauty of using both "V" nail and glue is I can make multiple frames quickly.  The process is:

1. cut the pieces

2. apply glue

3. clamp

4. drive in the "V" nails (two per corner)

5. immediately after driving the "V" nails remove from clamp and go on to the next frame.
