Another Newbee Question

Hi Jeff,

Can you share a little about the delta recommended technique?

you said earlier that "you put the bridge in the pressure cycle at one end, allow it to fill as far as it will, then when it will not push the resin farther, you start adding resin with a dropper, which will continue to push it farther."

I am guessing that the technique involves using the spreader to open the crack and filling it by dropping resin on top of it? What happens at the other end of the crack where it can't be spread without extending the crack?

:::Sticks hands up in the air::: Ok Jeff, I give.
Really though, I personaly don't like that technique you guys do because when its really sunny outside its really hard to do that without it curing on you in mid-repair.

Chips, generally there is only one "end" to a crack... the other runs to the edge of the w/s or starts at the break.

Also, often the resin will "wick" right into the crack without needing crack openers. There are some tight cracks that don't fill this way or they are real slow. It would help to use a crack jack in this case.

Come on man, use a shade you ninny {|=

Then the problem is...what? Quit being argumentative!

At the other end of the crack, make sure and pop a bullseye, which when done correctly, will make the crack run to the bullseye. This, once cured, will stop the crack from running further.

As far as spreading the crack, I will usually use crack expanders, when it's over 6 inches or so. The key is (and don't listen to Coit ), if you put a crack expander on the shield, leave it alone until the resin is fully cured.

Thank you very much for the great info and answers. I will be ordering the Delta bridge later this week.

I have one more question for the group. I think it was repair 1 who posted a list of gear he would buy if he had it to do over again. one of the items on his list was the Liquid Resins Bridge and pump.

I am wondering what this group thinks about the liquid resins bridge and does the different design offer advantages for some some types of repairs that the delta doesn't and visa/versa

Thanks again,

Dave

I had an opportunity to 'test drive' the liquid resins vacuum pump a ccuple of years ago. I found it difficult for me to use, because it required more hand strength than I am capable of. It probably works okay for those who are able to master it, but even so, I would be concerned about repetitive action stress injury (especially carpal tunnel). They claim it is a time-saving devicee. But if you start with equipment like delta or glass technology, you wont have to spend more money on accessories like that, because they provide all the vacuum and pressure power necessary.
