Jerry,
Thank you for your inquiry about the warranty of the Rock Chuck.
My intentions of this warranty was to make sure that when someone received my chuck, it would be of noticeable quality, and that they receive it in proper working order, produced to the intention of my design. It is also my hopes that they would see noticeable improvements to their machine vibration, sounds levels, flex shaft temps, and surface finish of thier carvings. This was based on confirmed tests on many machines before I was ready to post it publicly. It is also my hopes that this is would be the last chuck that they would ever need for the life of thier machine. (Note that if you somehow received a balanced, properly working QC, you might not notice all of these benefits, but would certainly see some of them).
To be free from defects in material means that if the material of any of the four parts making up the chuck was found to be defective, and fails from normal use of the chuck, I would simply replace it.
To be free from defects in workmanship means that if the Rock Chuck fails from normal use, due to being improperly manufactured, I would simply replace it.
Based on two years of data, I can tell you that i have not had 1 chuck returned because of either of the above. My beta chucks are still in use by several people. It is in my opinion that if there is something wrong with the chuck, you would know it the very first time it is used. Because of the simplicity of the design, there is an incredibly small chance something will go wrong down the road too.
To be fair, I can tell you that I have had 1 return of 2 chucks that were mangled beyond belief by vice grips, channel locks, and a grinder, I assume that it was because they chose not to use the wrenches i sell with the install kit. I am not going to warrant these for obvious reasons, but I am removing them from the "Z" truck for them free of charge.
Maybe i am too trusting, but i think that in this fine group, (that has become somewhat of a family to me), if someone were to try to hold a 3/16" shank tool in the 1/4" bit adapter, and they ruin the bore, they would :
1) Admit to their mistake, and just buy another bit adapter (replaceable for $79 and about 1 minute of your time)
2) Know that with me being the machinist that produced the chuck i would likely be able to tell what happened to it, and report back my findings, and we would settle like gentlemen.
or
3) If I were to (in the very unlikely event), have something ship out incorrectly machined, I would simply replace it.
I have, and always will, treat people with respect, and treat them right. I have tried hard to live by the golden rule...
I have no intentions of quitting this venture, and will stand behind my products so long as i am in business. I think you will find that this is the case with any warranty you may (or may not) get.
And FOR THE RECORD>>>
The Steel "Rock" brand sleeves used in the Rock Chuck, will work with the Rock Chuck sytem!!! I am not telling you what will work in the CarveTight Chuck, because i did not design, nor test it!
There is a reason that my design works (and perhaps why others don't), and honestly I do not care to tell you why!
I will repeat one more time though, Steel collets and sleeves have been used in daily production, holding carbide tools, for at least the entire 30 years that I have been in business. Machines in our shop range in horsepower from 2hp up to 30hp spindles. The average downforce "Z axis" capability is over 2000 lbs. We use them every day. I will point out though, that they are designed to work in combination with specific chucks.
Hopefully this helps people understand where I am comming from.
Thanks to those that have supported the "Rock Chuck" system!
Best regards,
Ron
