Doc's SAGA™ Epic Fail - Back to the drawing board

Recommended Posts

Hey Gang,

Well, back to the drawing board.  The first samples of Swing Arms we got into the field have failed miserably.  Thanks to all of you who have put up with the frustration of being guinea pigs.  If you have had one that failed, return to the dealer and he will refund your money, until the revised version is available.

If you have one that has not failed, use it until it does, so you can give us feedback on what happened.  Pictures are very helpful.

So some of the things that have been identified are.

1.  The strap, which I requested be made with some kind of UV rubber with fiber reinforcement was not made with reinforcement, so it stretches and then breaks.  It also needs to be about  1 1/2 inches longer with one more adjustment hole.

2.  The pivot ball joint has way too much play in it.  It should only rotate 360 degrees with no side to side movement.  Initially I thought it would give more freedom of movement, but it is movement that is not necessary and causes undo stress on the joint and a feeling of instability.  The purpose of the ball joint is to only allow the arm to move up and down so it does not break.  But the opposite is happening, because it has so much movement, there is a lot of stress on the part.  That is an easy fix, the collar has to be redesigned to restrict the movement.  I'll try to attach a pdf file to show you what I am talking about.

3.  The pivot joint, the one that has a pin in it that allows the Swing Arm to swing out and away from the detector is too thin and flimsy.  This was supposed to be made of Nyglass, but I think they used something that was not suitable for this part.  This will have to be redesigned to be thicker with tougher material and a more substantial nylon pin that will be sonic welded into place.

The concept and functionality is solid, it is just the materials and some of the design that needs to be corrected.

Now I don't know many manufacturers that announce to the public that they "screwed the pooch" so to speak.  But you guys have always been very helpful with ideas and suggestions and helping me field test all this crazy stuff I come up with.  So I wanted to include you on this.  And trust me, this is the process I go through every time with everything I develop.  From initial concept, to design to prototype to pre-production to testing to modification and back to testing and then to full production and shipping and delivery and to the market runs about 9 months to 1 year.  Sometimes things go very smoothly, sometimes, not so much.  It depends on the complexity of the item.  Unfortunately for this SAGA swing arm there are so many different molded moving parts.  2 Molds for the handle, a mold for the storage clip, 3 molds for the pivot and pivot ball joint assembly, 1 mold for the straps, a mold for the buttons in the fiberglass rod, extrusion mold for the fiberglass rods.  About $10,000 in mold costs alone.  Fun, right?

However, I have never brought to market anything that I don't use myself and stand behind 100%  And the SAGA Swing Assist Guide Arm will be no different.  So your patience is appreciated as we work on SAGA™ Version 2.0

Speaking of production, the "G Spot" scoops are in production but I had them made with a satin finish as in the attached picture.  The shiny ABS material caused too much glare in my opinion and was too slick allowing small gold to slide too easily.  The top picture is the new satin finish and the bottom scoop was the shiny prototype.

Standby while we work out the bugs.  Thank you and Happy New Year.

Based on what I'm seeing, the re-design does not need to be a 'ball' if you only want it to rotate.  Some UV resistant plastic and a Teflon washer should be sufficient.

If it were me, I'd buy the correct materials and machine and prototype the parts to prove functionality before I spent a dime on making molds.

Why don't you manufacture in America?  When you're trying to produce a product that will have a long service life, the initial cost to the consumer could be higher based on the idea that it will last and possibly be on only one they have to purchase.  IMO.

Good Luck

Hey Doc ... On either one of those scoops I would do exactly what I do on a new pan or a new scoop in the past. I take some coarse steel wool to the surface to rough it up a bit. I like the new design but would still like to see a little saw tooth on the edge for those holes that need a little extra work but not with a pick necessarily.

Keep up the good quality work!

Happy New Year!

You only get better with failures, not successes. Keep up the good work.

Haven't used this item, but I do appreciate the honesty. Second try is a charm!

I just installed your carbon fiber rod kit on my GPX 4500. Very happy with that so far.

Regards, Kyle
