Marketing ploy?

[WillSDQ]

There are some companies that are claiming their systems keeps the resin separate from the air and moisture that is initially removed from a break. One company has a very simple method of a chamber that you twist, after the initial vacuum cycle, which allows the resin to drip into the break on the first pressure cycle. They claim that this feature is optimal for a repair as it keeps the resin "pure" during repair.

But what confuses me is all of these companies tell you in fine print that it might be necessary to cycle the the break three or more times. What happens? Does the resin jumps back into the vessel that originally contained it on the initial vacuum cycle? I don't know much, but, that doesn't make sense. It is obvious to me that that all resin, no matter which kit you use, will be expose to the air in the break at some point. Am I correct about this? Is this just a marketing ploy?

I think you have already figured it out LOL

Congratulations WillSDQ, you are 100% correct. Starting with pressure vs starting with vacuum is a matter of preference, but as any engineer will tell you there is no way that the resin will never touch air with current technology. Maybe in outer space, but not here on earth. This should be very obvious to everyone, but some people will believe anything they are told and never take the time to really think it through.

It is mainly about politics and marketing. Not that removing moisture, filling the void completely with resin and curing properly would not be important issues, in fact they are and we will all agree (I believe), but to claim that other systems ''just don't measure up'' is, let's be blunt, BS. Hey, what has happened, this is a free world! As long as the end result is according to what we all in this industry agreed upon as ''a quality repair'' ....were all doing fine -whatever system is being used.

I like your style WillsDQ,

You thought it through and logic has shined! You have asked great questions. Lets face it, many systems if not all when in the hands of a skilled technician will produce structurally sound repairs. So how are so many MFG's to separate themselves then? The marketing of the technology and of fundamental differences. Sometimes that marketing information may be misleading and confusing. It is up to the consumer to disect and process it unfortunately.

So if most equipment will do good repairs when trained properlly on that equipment, consider what is really importatnt to you if you were working in the field, is it?

1. How tooling feels in your hand (you know, when something is designed right it feels like and extension of your hand, not awkward in your hand)
2. Ease of setup (how does the tooling attach, adjust, hoses, vacuum pumps)
3. Ease of use (how awkward it is to adjust equipment during repair)
4. Ability to easily adjust to the repair location and during the repair (verticle,edge,curve)
5. Speed of repair (you know this is not drag racing so the actuall time differences are negligible to say the least.)
6. Ease of tooling breakdown for cleaning (you will be cleaning quite a bit)
7. Minimal seals and o-rings (this means more to buy in the long run)

My tooling preference of choice is Delta Kits for the reasons I listed and many more. It really is a no hype, well designed and contrusted, consistant performing tooling and resins, super simple to use and maintain. My intent was for you or anyone to think about what will be important to you in the field. So now go back and look at the brands you were considering without falling into the marketing campaigns web. Good luck to you.

SGT,

The feed back you provided should be required reading for anyone that's considering entering the WSR business. The 7 points you made (especially the 1st one) were very insightful. Having grown up around craftsmen (machinists, watch repair and furniture makers), the two statements I heard most often were; "The right tool for the right job" and "A well designed tool has a certain feel in your hands that makes it feel like it's a part of your body".

While I don't have much experience with the products sold by other WSR companies, the components that Delta Kits offer, has that "certain feel". Recently, Delta Kits has stepped up and introduced a "centering tool" (and it matches the same standards of the rest of their equipment).

While some techs have (out of necessity) improvised by using a "thin drinking straw" or an "awl" to get an accurate placement of the injector over a break, these items are best used for the purpose they were designed for; stirring coffee and punching holes.

Now that this tool is available, for the grand total of $8.00, a WSR tech can get a centering tool that was designed just for centering, "fits" VERY well into the injector body and leaves little room for error when accurately positioning the seal over a break.

Just MHO,
