Peter"Salt wood" means what?
I have seen this term used, presumably in a derogatory sense, but I don't know what it means.
Thanks, Peter.

BROWNING SALT WOOD EXPLAINED
Dear Technoid,
Please discuss the Browning Superposed salt problem and how to detect
this defect. I have not been able to find any reference to it in the
shotgun literature.
Bill
Dear Bill,
The best discussion of the Browning salt wood issue is in Ned
Schwing's "Browning Superposed" book (Krause Press, 1996). According
to Schwing, in the mid '60s Browning needed a better supply of high
grade walnut for it's guns. A California contractor had a large
inventory of good walnut taken from clearing power line right of ways.
Demand for Browning guns was at an all time high and the usual kiln
drying process for walnut was too slow to produce what was needed.
Rapid kiln drying also produced cracks in the California walnut.
Morton Salt had developed a salt solution drying process successfully
used in the furniture industry with good results. This cured the
walnut much faster than the kiln method. Browning tested it and there
were no problems, so Browning bought the process in 1965. "In an area
roughly the size of a football field, five-foot by five-foot by
eight-foot stacks of stock blanks were covered with salt. The salt was
supposed to leach out the moisture and dry the wood quickly. The
process did accomplish its purpose but the moisture that was drawn out
of the blanks on top of the stacks ran down into the blanks below,
resulting in a brine solution that soaked the lower wood blanks."
(Schwing, pp 246) The retained salt reacted with the gun metal with
the finished stock was installed. This caused the rust associated with
"the salt wood problem".
According to Schwing's interviews with Browning's Harm Williams and
Val Browning, all the salt curing was done in the US and affected at
least 90% of all Browning stocks from made from 1967 to 1969. The
problem continued to show up until 1972, but in smaller numbers. It
was then that the entire supply of walnut blanks was burned and
replaced with traditional kiln dried wood.
To detect salt wood on 1966 to 1972 guns, first check for outward
appearance of dark or discolored spots. Check every place that wood
meets metal, as on the rear of the forend and at the head of the
stock. Rust on the metal will be apparent if there is a problem.
According to Schwing, the definitive test is to remove the butt
pad/plate, scrape away a little wood from the exposed butt and apply a
1% solution of silver nitrate to the fresh wood. If the silver nitrate
remains light purple, there is no salt. If the silver nitrate turns
white, you have a salt gun.
If you can prove that you are the original owner of the salt gun,
Browning used to replace the wood for free and will probably still do
so. If you bought the gun used, you are on your own. I got a used
Superposed 410 with salt wood about ten or twelve years ago. Browning
charged me about $250, if memory serves, to replace the wood. It
wasn't free, but it was certainly a bargain price. I don't know what
the numbers today are.
By the way, Browning wasn't the only one to get taken in by the salt
wood walnut curing process. I've heard that some other gun companies
did also, but weren't quite as up front about dealing with it.
Best regards,
Bruce Buck

ramrod340An excellent write up. If you are buying a Browning from that time frame I would also check below the wood line.

Duane WiebeForrest...good write-up...I heard of another slightly different version in that Calico Hardwood was the one that institued the process for the pleasure (and business) from Browning....Everyone pleads "not guilty", but Calico Hardwood (N. California) was pretty anal when asked to replace the defective wood (which they sold to ME....and other stockmakers, I'm sure) Calico is not real high on my list of wood suppliers!!!

Anyone care to speculate on the Corporate wisdom of this decision? I don't get it.

PeterDamn, ForrestB, that's about as complete an answer as I could wish for. Thanks very much!

Dr.KExcellent post !. I don't mean to hijack the thread , simply posting this in the hopes everyone who purchases stock blanks understands ALL aspects of Air verses Kiln Drying or KD wood .
FYI ; Vacuum Drying
This method has been used off and on since the early 1900s. Because of costs involved, it did not receive much commercial attention until the 1970s. Placing a partial vacuum on a closed chamber lowers the boiling point of water below 212 degrees Fahrenheit. This reduces the amount of energy needed to dry the lumber.
Vacuum drying is useful in drying thick, high value pieces of wood, such as large turning stock or dimension parts. Dense woods, which are difficult to dry because of excessive shrinkage, can also be successfully dried in a vacuum system.
Dehumidification kilns
This kiln captures the energy needed to dry wood from the water in the wood itself. Warm, dry air is circulated through the lumber package and absorbs the water from the lumber. The warm, humid air passes over condenser coils in a dehumidifier. The process of condensing water vapor into liquid allows the recovery of the energy required to evaporate the water from the wood in the first place. The process is essentially identical to an air conditioner.
Typically, this kiln is more energy efficient. Also, the construction costs are somewhat lower, since conventional well-insulated, wood-framed buildings can be used for the structure.
The disadvantages include the cost of power. Usually, the kiln is electrically powered. Also, the maximum temperature is somewhat lower and the water condensate may contain unwanted chemicals. Generally, it requires more time to dry the lumber by this process when compared to a conventional kiln.
The combination of these two types of " Kiln Drying " are what the " Doctor Ordered " where ever and when ever was practical .
Please have a Look at these two URL's in order so as to understand why I insist on KD blanks or the very least KD the Air Dried blanks .

Would you post that under the reference material thread?
