What tips and trick can people offer me for getting that last bit of air out thats on the our edges of the larger bulls eyes?
I am using a mixture of Esprit and Delta kit, but the bridge and injector is Esprit. I can move it but find that the vacume just cant quite get that last bit out sometimes, no matter how many times i cycle it. One thing that does help is to use my micro torch to heat while its on a vacum cycle and sometimes i have to put more of pressure on and pre-cure. What do people here suggest?

If your happy with equipment, why are you posting about problems with its performance on bullseyes?
I'd probably suggest contacting your equipment supplier and ask them these questions. I'm sure they could help!

Another suggestion. Are you sure your only pushing air and not moisture?
Any moisture present during bullseye repair will cause you problems. If in doubt with identifying water in damage always dry out prior to inducing resins.

So the answer is - if you are having issues, just buy a new load of kit!
Not really why i joined this forum. You are not really being very helpful StartQwest, sorry
But anway, i just saying that my technique may not be 101% and i am looking for new ideas that may help me with my existing kit, thats all.
If people can give some USFUL advice and that does not work, then yes i will think about new kit. But Esprit is very highly regarded in this part of the world, as is delta.

Madscot,
Relax.....I'm not trying to get you to buy new or different equipment. I just simply stated if your having problems, best place to start is to call your equipment supplier. Have you tried that yet? If so what did they tell you?
I'm trying to understand why your having problems with bullseye repairs but to be honest, it could be the either the equipment your using or simply how your using it.
Could you provide more information? Like every step your using to repair these?

Hi madscot!
StarQwest is right about moisture. We all need to be mindful of its potential presence.
I have both Glass Mechanix and Delta equipment.
My equipment allows for a fairly strong vaccum and sometimes I don't get all the air out of a stubborn break initially. So a couple things I do to rememdy it is this...
1. Slow down, be patient and work the repair. Sometimes resin just takes a while to travel throught all the damage. It has sometimes taken 30 minutes to fill a simple bullseye. Most fill within a few minutes, but there are times that it does take a while because of the makeup of the damage.
2. Reduce stem pressure. (Basically unscrew the injector a tiny bit) so that it is not pushing against the glass too hard, but not so loose that your injector starts leaking). Sometimes excessive stem pressure can choke off openings within the break - slowing (or stopping) the advancing resin.
3. I use a long skinny steel probe and insert it down the throat of the injector while the bridge/injector is set up. I gently push the probe against the pit of damage (while there is still resin in the injector). As I push, hold, and release... push, hold and release, I watch the resin and air pocket(s) in the break. In most cases the air will surface as the resin seeps further out into the damage. Using a probe in this manner opens up any tight or closed openings and allows for better resin/air exchange.
4. I also use heat, but I would rather not if I don't have to. I use heat as a last resort, but it does work.
5. Some manufactures advise to ALWAYS cure under pressure, and some advise to NOT cure under pressure. But if you have a break that appears fully filled under pressure, but an air pocket remains in the break if not under pressure, then that to me is a good case for curing under pressure.
Good luck, and stay with it.
