About 5 years or so ago Pat Diveney cut me a heck of a deal on a Lake Salvage shaft that he said he would not be able to sell because of the imperfect looking color in one place.
So he made it into a 30" break shaft for my Ebony break cue he was making for me. About a year later it looked a bit crooked to me, not much though. Pat said to send it back and he would straighten it or send me another one.
A month or so later I got it back straight as could be and it still rolls and looks straight. Pat said he has thought about making a video on how to straighten shafts, but is to busy. Next time I get back to my birth place in Iowa I will try to stop by his shop and see if he has time to give me a demo.
Personally, it worked for me so far, but I can also see where it may not always work. Wood just has a mind of it's own some times.
(I also believe based on what I have learned about Lake Salvage wood, submerged, etc. The time spent submerged n cold water changes the impurities in the woods molecule's. ) Don't ask me to explain it. LOL
i read that the secret to the tone of a Stradavari may’ve been the fact that the wood was
stored in sea water before it was dried.
