How do you keep LT420 from running?
« on: August 30, 2010, 08:59:00 AM »
Some of you may have seen my recent thread about the ’60 Kodiak that I picked up last week.  After I got it cleaned up and inspected, I found one very small nick on the edge of the lower limb that I’d like to seal up with LT420.  I’ve used this glue on several bows in the past and my experience has been that the stuff runs everywhere (even when using a syringe).  Every time that I’ve used it it’s been before I was going to sand the bow down and refinish it so I never really worried about the glue tracks.  This bow is in great shape and while I want to seal up this nick, I don’t want to ruin the finish with glue tracks.  

My question is; how do you control this stuff?  Will masking tape work or will the glue wick under it?

Thanks,
Brian

well if using a syringe to glue a very small spot and you do not want LT all over your bow.I hold the syringe over a paper towel and then depress the plunger until I have one drop hanging on the end of the needle.Then you can tap on the syringe and shake off that drop and the next drop will be rather small and can be placed anywhere without running all over your bow.You'll kind of have to play with the syringe a bit until you hit the drop just right but it works great.One other thought is you can use LT gel but it does not dry as clear as 420 and is really hard to sand off the excess gel bd

Thanks, guys.  Had to order a new bottle of glue so I'll practice the technique and give it a try when it arrives.

I couldn't remember where I bought the last bottle so I searched on Google and found it at CSN Stores on sale for $15.99.  I'm not sure if this is allowed, but here's the link:

I have found that gravity can be a big assist here. I rotate the bow so the area I  am injecting stays at the lowest down hill position ( bottom most). this way I can sometimes let a bead hang thus allowing the crack or whatever I am filling wick the stuff in without it running all over the place. This of course only works sometimes.
Has anyone here tried the Tight bond version of "thin" ca glue? It comes in three viscosities Thin, thick and gel.

The following method has worked for me. Put a small drop of ca glue on a piece wax paper or tin foil. Use a small piece(1" to 1 1/2" long) of small diameter music wire, .015 or so and dip the end of the wire in the drop of glue and then then touch the end of the wire to the dinged area. You will have to move fast so you don't stick the wire to the bow. You may need to try different wire diameters depending on the size of the ding. It also helps to put a 90 degree bend in the end of the wire where you hold it.

I have also also bent the wire double so it would hold more glue for bigger dings.

Always, try it on a scrap piece of wood first to make sure you have the amount of glue you want.

You can get music wire, (sometimes called piano wire I think), at hobby shops. It comes in many different sizes. The glue will build up on the end of the wire. Just scrap it off with razor blade or hobby knife. Jim
