Ugly Double BullsEye

[Evergreen]

I had a really ugly bullseye come in a couple days ago. What was bad is that it had two impact points about 2" apart. There were actually 2 bullseyes that connected. I was not sure what to do so I put a chip saver over the top hole and filled from the bottom. Problem was that I could not build up enough pressure, the resin would leak from beneath the chip saver. I think I figured out a solution but after it was too late.

What I want to know from you more experienced guys is if what I figured out would actually work. As I finished curing the pit resin I had the thought that maybe what I should have done was to have put pit resin in one hole, probably the one on top and cured that with the lamp. Then fill from the other hole and I would have been able to get more pressure.

Thoughts?

That's exactly how I do it.

you hit the nail on the head .... but to stay consistent for Jeff I will say DRILLLLLL!!

I had a repair like that today. It leaked out one side while I was filling the other. I ended up wiping the resin off, putting a double layer of 2” wide super clear packing tape over both of the spots. I drilled through the tape and filled one side, repositioned the tape to cover the first side and filled the second side with my injector against the glass. I removed the tape and cured them both at the same time and it worked well. (Hindsight…I could have simply put another layer of tape over the first repair and drilled the second. Doh!)

I have used electrical tape in the past so I could cure one side without curing the other. I have observed that when breaks are very close together, filling one may partially fill the other and make it difficult to inject resin completely into the second break. The clear tape worked better because I could monitor the fill through it and wait until both sides were filled to cure one time.

Great post, it,s fun to have posts where we can share techniques and learn from(with ) each other.

I use a combination of the above techniques. I will first try to create a vacumm, if too much air is being pulled from the ajacent pit then I go to plan b. Plan B consists of putting a drop of pit filler and a piece of curing film over the second pit. I the continue with the vacumm, the vacumm will draw the pit filler partialy into the break, I then follow with an injection, if the 2 breaks are interconnected well enough this will fill them both(those of you using an injector that is hydraulic pressure only, you may need to adjust the pressure slightly as the break fills to maintain presure). I will follow this up by curing , always leaving the curing tab in place. If the second break doesn't fill from the first I will remove my injector from the first, add some pit filler and a curing tab to the first, then set up on the second, having not cured the pit filler the resin in the injector will pass trough it(as will the air on the vacumm cycle) and the break will be filled. I then cure with the injector under pressure to hold everything in place. After curing the current set up i remove the injector, scrape the pit of the first and fill the pit of the second, cure again then finish up in the normal manner.

I repaired one of these not to long ago . With very good results ,First I put a drop of pit filler on one of the impact points placed a cure sheet on it then cured when I have a large bullseye I allways drill before injecting my resin especially if it has any legs or waves as I call them around the out side edges. So after filling the drill side, the damaged area almost always fills completely . If not You will have to drill threw the first pit and fill it .
