Difficult Materials Cut By New Tacoma Factory Installing Tungsten Carbide Saw Improvements

Cutting difficult sto,ck which has been a problem in vario_qs industries, is being successfully accomplished by a new Widia Tungsten Carbide Tipped Inserted Tooth Saw made by Simonds Saw and St'eel Company of-Fitchburg, Mass.

A Widia Tipped Saw ins,talled in a plant in October, 1930, cut. asbestos composition brake-lining for eight months before it was resharpened and then not over .01{' was removed from the top of the tooth. Formerly, in this

The Washington Handle Company, Tacoma, Wash., are at the present time installing one of Moore's Reversible Cross Circulation kilns. This kiln will replace two obsolete natural draft kilns. The new kiln will be 29 feet wide bv 72 feet long and an interesting feature of the installation is that the mechanical equipment will be located at the side of the kiln loads instead of underneath rail level or above the loads as is customarv.

The Washington Handle Company are exclusive manufacturers of handles and the new kiln, which is of the longi- tudinal shaft type, was especially designed for drying -fir and hemlock handle stock on a progressive basis. Wm. W. Kilw_orth is p_resident and generil manager of the Washing- ton Handle Company. H. N. Howard is secretary and F. R. Kilworth is tieasurer.

Japanese Oak

factory, carbon steel saws cutting five pieces at one time had to be resharpened every hourl The-Widia Saw cut 15 pleces at one time over a period of eight months. In another plant for over two months one of these saws has been cutt'ing sound-proofing board with cement binder. More than 50,000 feet of one and two-inch thickness have alreadv been cut without dulling this Widia Saw. The previous record with a carbon saw was 2.000 feet.

In several of these specialized industries this saw appears to be the answer to their cutting problems. Increased pro- duction, more feed and greatly ieduced cost of sa* maintenance are amazing results which the Widia Saw is sivins. idia is giving.

In view of the verv definite trend toward the use of Oak in the manufacture of furniture. which has recentlv {ranifested itself, it may be of interest to users of Japanesl Oak to know that there is quite a variation in quaiity in the different types of Japanese Oak, as well as inour domestic Eastern Oak. According to John Ziel, of. Barg, ?iel & Co., San Francisco, which firm ii one of the largeif importers of Japanese Oak and Birch on this Coast,lhe texture in Japanese Oak varies according to the districts in yhi+ this Oak is grown. fn a recent conversation regard- ing Japanese Oak, Mr. Ziel said: "On my various visits to the interior of the island of Hokkaido (Japan) where most of our Japanese Oak comes from, it became quite evident to me that the Japanese Oak grown on the Easiern Coast of the Island was usually hard-textured. while the stock from the interior and more westerly portion of the island was milder and softer-textured. The leason for

The plate is of Exoeptionally tough steel with te?ttr 3t Simonds quality alloy. Welied to the cutting edge are inset sections of this new wonder metal with the Jutting g9i1ts almost- 9qual in hardness to a diamond or sapphiri This tooth withstands wear to a remarkable degree, holding its edge for a long time.

Some of the difficult materials which the Widia Saw cuts include asbestos pipe covering, asbestos impregnated brakelining, friction block, ebonite, brass wire ieinforced brakelinirrg, fireproof insulating board, hardwoods such as teak, ebony, _quebracho, and rock maple ; also bakelite, hard rubber, bakelite fibre insulating pipe, fibre conduits,'glued plywood, linoleum, fireproofing woods and floor compositioh.

this hardness of the Oak grown on the Eastern Coast is that the trees on this Coast bear the brunt of the Pacific winds, thus ,causing much slower growth and consequently a harder texture. It is a well-known fact that in Japin thii harder stock does not bring as high a price ai the softtextured Oak, and it is therefore not sulprising to us to note certain sales of Japanese Oak made here in-this country qt somewhat lower prices than the price of the better quality stock.

"The condition mentioned regarding the difierence in texture according to the location of the forests on the island is repeated in the Philippines, where on certain islands the forests o1 lhe coast,-which receive the strong Pacific winds, contain harder textured trees than those ii districts less exposed. In Philippine woods we of course have, just the opposite condition to contend with, as it is the firmer textured Philippine which is more in demand, while in Japanese Oak the softer textured stock is the more desired."

Mr. Ziel states that, although sales for Firsts and Seconds have not been up to normal so far this year, there has been an increasing demand for No. 1 Common & Selects and No. 2 Common Japanese Oak.
