Re: Who has the Borka torque kits?
<div class="ubbcode-block"><div class="ubbcode-header">Originally Posted By: kortik</div><div class="ubbcode-body">Gentlemen,
Thank you for your kind words about my torque driver. Shot Show closed yesterday, I'm still in Las Vegas, but should be back home shortly... Show was fun, picked up 4 more dealers, all good brands, to sell my products in the U.S. Not looking for any more U.S. dealers.
Anyway, I do not believe I know everything, but with my 30 years in practical engineering, Ph.D. in mechanical engineering and being a licensed PE in State of Michigan, which is, seriously, a big deal as far as I'm concerned, I thought I would give my reply to this "calibration" issue.
In short, most people do not realize where this calibration thingie comes from. In 99% of the cases, it comes from the need of CORPORATION to pass QS audits. To pass it, company must show re-freshed and annualy (or every 2 years) updated caliberation stickers attached to the something used for production or QC of company products. Whatever needs to have such sticker to pass audit may be perfectly fine, but company MUST still have it refreshed to be in compliance with formal requirements. Let's call it PAPER WORK part of th business.
In reality, if you're an individual user, you need this sort of frequent calibration as much as you need your balls painted in red to look attractive to the opposite sex. Say, you got
calibration certificate with your tools, which is fine in theory, but I wonder how much use you'll have for it in real life. Will it be actually used for the physical tightening of the fasteners? Is this piece of paper all you need to be completely happy?
Professional engineers know very well or at least may have an educated guess based on prior research, how the compression spring under specific constant load will behave, how much relaxation of the sprng will occur in certain number of years and how it may change force (or torque) values. No magic here, it's what prefessional engineers do for living. My torque drivers do not need annual "calibration", because it designed by me, the professional engineer, who is also, as I was told, qualifies as a gun nut, who knows a bit about this stuff, and if I say it is good for 50,000 cyclesor 25 years, whichever comes first, I'm putting my PE license and all my credentials as an enginner on line.... I do not sell my tools as sales guy, I sell my tools as an engineer who also managers sales.
If design is good -,= you do not need to worry about calibration, because it is simply not applicable in this case. If Seekonk, say, suggests calibration after every 5,000 cycles, or once a year, it has very little to do with real world situtation, unless Seekonk makes a super crapy product, which, I beieve, is not a case. It's just a way to make extra money for company by providing "extra services".
Borka Tools torque driver DOES NOT need to be recalibrated for at least 25 years or 50,000 cycles, which ever comes first. After one of this factors takes place, you can expect up to 5% drop in output torque, which is still not a big deal, as far as I'm concerned, but f you're concerned, <span style="color: #FF0000">I'll do spring replacement and re=calibration for you for $25 + shipping.</span>

Well in that case, keep an eye out for mine in December 2036!
