CA GLue ??

Splinter · 08-05-2006, 08:08 PM

I have read several threads with a reference to CA glue. What brand CA glue is best and how is normally used in WW'ing?

Can't answer the brand without going to the shop. I use it for gluing in the tubes into pen blanks and want to learn to use it for a finish on the pens. I also use it if I want to secure a knot in a piece of wood, etc.

CA glue stands for Cyanoacrylate Glue.. aka super glue. It comes in 3 consistancies.. thin (super glue), medium, and thick.

I use the Loc-tite brand from Lowe's, it only comes in thin. I have found it to be very handy

Dolan, I use a brand called Hot Stuff made by Satellite City. I believe both Woodcraft and Klingspore carry it. As Clay pointed out, it comes in three different viscosities. I use both the thin and the thick which is more of a gap filler. They also sell an accelerator (smells like nail polish remover) that you can spray on that will bond your pieces together instantly.

I primarily use it for gluing small pieces, fixing splits/tear-out, and filling small knot holes prior to finishing.

BTW, I have found that if you store your CA glue in the refrigerator it will last a lot longer.

When you use the CA glue to fill in small gaps around a inlay or for filling a knot for instance, does the glue blend well when you finish the piece or is the glue obvious?

I watched David Marks on Wood Works last night use CA to glue a piece of wood to the bottom of a block of wood that he turned into a bowl, so I guess it is very stong. By the way that was the first time I have every seen his show where he had any sawdust or wood chips on him. How does he stay so clean doing wood working?

There is accelerator for CA glue, but, you should be aware the accelerator only sets the glue it contacts. For example, when gluing a pen tube into a blank, spraying the end with accelerator only sets the glue at the end, if one starts to work the piece very quickly, it can come apart. The thick CA glue literature indicates a set time of 50 - 60 seconds. Using accelerator will tack a piece in place, but wait a minute before applying any force.

Let me add that when the accelerator is used the areas that have been accelerated are much weaker.

If you use accelerator on a pen that has a ca finish, it will also pit and bubble the final finish, probally due to the heat it generates.

Question on CA glue. I have a marble (or some fancy rock) end table top that I have to repair this week. Sometime during shipping from the factory and the time it was opened at the furniture warehouse, it must have been dropped on it's corner. There is a hunk missing about the size of a silver dollar. It's not soild marble, it's only about a 1/4 marble veneer that has been glued to a chip board to make up the top and sides of the top.

To do this repair, I'll replace the missing piece with bondo, mixup some powdered blendal piqments and blend in the right colors with an artist brush. Rebuilding, painting and blending the missing piece to match, doesn't consern me. It's the finish that conserns me. Can I use CA to create a thick high gloss finish that's the same sheen that a marble table top would have? If so what steps would I need to take? Which CA would I want to use? I assume there will be some sanding but with what grits? Can I polish with a high speed buffer and atuo body paint scratch remover and buffing compound to get an ulta high sheen?

Thanks

You can buff the CA to a high polish. I use Micromesh to a grid of 12,000. (Which is not the same grit as sandpaper). Most people use a Beal buffing system to give the ca a final buff. I would think the ca finish would be brittle, depending on how big the spot would be. It would cure to a clear gloss. You would want to use either Medium or Thick CA to try this. You can make it as thick as you want, just keep building it up. Getting it on nice and even may be challenging.

Disclaimer---- I am assuming this is an approiate application for CA, which it may not be. I've personally never tried.

jeff... · 08-07-2006, 12:21 PM

Clay I don't think the finsh will be all that thick, nothing at all like a bartop finish. With bondo I'll build up the repair just below the surrounding surface. I'm looking for something that will give a little depth, be rock hard and crystal clear. Sounds like CA may just do the trick.

When I tackle this bad boy - would anyone be interested in a pictorial?

It's basicly the same method I use for repairing broken corners and larger chunks missing on wood furniture. It's bondo and painting in the grain, only difference is this is rock, which will require a different finsh.

Thanks

Jeff,

I for one would like to see your technique on "graining" and think this would be very interesting to see.

Ok, give me a few days and I'll snap a few pics with the warehouse camera.

Thanks
