Help with Delta on Vertical Glass

[jonnyques]

Hi all, Well I did my first transport to day. So now Im looking for advice on how to use the delta bridge on vertical or near vertical glass. The problem I ran into was getting the resin to stay at the seal. I put the resin in with the dropper , screwed in the injector, and looked at what was going on from the inside. What I saw was a large air bubble in the seal. I ended up putting in 3 times the normal amount of resin to try and get a larger volume of resin in the seal and less air. Because the injector was horazontal the resin would just run out of the seal area. I thought just screwing in the piston would force thr resin into the seal area. This didnt seem to be the case. I thought about trying to preload the injector with the piston in place, but cant see how the resin wouldnt just run out when I put it horazontal on the glass. I know liquid Resins and Glass Mechanics say their units hold the resin in the seal area through capillery action. Right now I think that may be the way to go if truck fleets are in my future. This repair turned out to be a big pain in the arse. Any suggestions would be great! I know Delta say their unit works fine on vertical glass, so Im looking for the Facts on how to do it.
Thanks all

We do a fair amount of vertical, go to the feed store and pick up some syrenges and needles. The needle should be fairly large and long enough to reach the glass. They are fairly cheep and readily available. You'll get the jest. They (Delta) recomend screwing the leveling screws to make the barrel of the injector point downward but this method is better in my opinion so..... Oh, and clean the needles frequently so as to not ruin the needle between uses, Scott

I agree, I use syringes for more accurate measurement, plus you can put the syringe down through the injector throat until the needle touches the glass. The resin will tend to stay put and not run out because of "surface tension". Now that the resin is where you want it, you are ready to start injecting with the injector.

I don't actually have a Delta bridge but have used their resins and droppers before. What I've found that worked well was extending the dropper using a simple cocktail straw to get the resin directly to the bottom of injector barrel. A box of them will last forever since they can be cut in half for this purpose. Another thing I do on verticle repairs is line up the injector seal with the pit just inside the bottom edge instead of centering it. Requires less resin to cover pit.

I have done alot repairs on trucks and found that a bottom load injector was the way to go. You can get the job done with others but I just found it easier all the way around. If you are busy, having 2 or 3 injectors will help you make more money anyway.

Park it on a big hill facing upwards or jack the front up or try another type of injector. Most screens have a slight tilt back so you should not come up against this problem all the time. I use plastic Novus injectors or Esprit and you can front load both of these and it is the surface tension of the resin that holds it in place not capilery action as those other guys say.

jonnyques, if you are looking for syringes, try page 4 of Deltakits accessories they have a few to select from.

One word of caution while using especially a clear syrange and needle is to keep it protected from the U.V. rays as soon as it it used. It seems to cure very hard and very fast in the clear plastic.

I agree on syringes. Right after I use the syringe, I immediately do two or three cycles of alcohol or acetone. I keep the syringe filled with alcohol or acetone until I am done with my repair and I am cleaning up my equipment. I then push the alcohol or acetone out, pull the plunger out of the syringe, pull the blunt needle of the tip of the syringe and blow them out. I hold them up and look through them to make sure that the passage way is clear (especially the blunt needle) because it is so skinny.

I have 3 syringes and keeping them clean has enabled me to use them for an entire year. They will probably keep on lasting as long as I keep them clean with no chance of resin hardening in them.

I am new to the wsr business and doing repairs for about 6 months or so. I live in a resort area and have had a number of motor homes to do. I use Delta equipment which with their Great customer service makes them the best for me. Like stated before when I do RV windshields I adjust the leveling screws to put the injector at an angle and after injecting the resin I adjust the leveling screws to normal while keeping the pressure on the seal so no resin escapes. This system has worked very well for me on vertical windshields. ..............Regards.........Tom
