Accidental gouges, contamination with the wrong grit, in one case, bad cooling water with sand in it, and in another, a worn-out prepolish lap had thrown loose diamond all around the machine!
BATT Laps, as with any other polishing lap, are intended for maximum diamond retention...So naturally, if a contamination accident happens, they will "do their job", and retain the contaminant!
This is where the advantage of a solid cast lap shows up! Rather than discarding them, they can simply be resurfaced, many times. I have had people return laps for resufacing after ten years of use. They end up with what is essentially a "New" lap, just .040-080" thinner. Thus, the BATT™ lap probably has the lowest cost-per-year than any lap on the Market.
I will continue to resurface the laps because at today's prices, people are going to want to do so, and who could blame them? EMail me in advance so I can schedule a resurfacing session, and give you a shipping address and maybe I will be able to do more than one at once.
Send the damaged lap, with $44.00 (This will INCLUDE return shipping to you!) and I will try to turn it around quickly.
NOTE: LAPS THAT HAVE BEEN DROPPED ONTO A HARD SURFACE USUALLY HAVE GRAIN DAMAGE AT THE EDGE SO SEVERE THAT RESURFACING IS DOUBTFUL! BATT™ is designed to be a work-hardening alloy, so that it wears well and entraps diamonds.
I have also had a few returned in this condition under my (generous) warranty. I am proud of the title of my warranty page, but this has to start working in both directions, to be fair.
Things happen.
NEW RESURFACING POLICY EFFECTIVE January 22, 2007:
Because of the outrageous increase in metals prices the last year and a half, and the new 2007 alloy I have to stop my "New BATT for your old one and $40" deal.
