Proper Chain Saw File Handles Continuedfrom Previous PageWhen making the handles I used such chunks ofwood as were handy. In fact, one could cut a handlesized branch, work it up a bit with a pocket knife, andjamb the tang of the file into the center pitch...but thatwould not be woodturning. Instead I used some blanksabout 5” long and about 1 1/2” squarish (some were abit more rectangular). AND I wanted a ferrule to assurelong handle life and to avoid unsafe splitting outwhen filing.Figure 3. The ferrules were cut from old electricalaluminum conduit.The ferrules were cut from old electrical aluminumconduit. Figure 3 shows the result. I turned the tenonwith a slight taper, and longer than the ferrule, doingtrial fitting and carefully reducing tenon diameter untilachieving a snug fit. Then I put the file into the top ofmy bench vice, opened just the two opposite edges ofthe ferrule on opposite vice jaws. Then I hammeredthe handle into the ferrule for a press fit. At that pointI remounted the handle in the lathe, finished the woodturning,and used a parting tool to cut the tenon flushwith the ferrule. A few drops of superglue were addedat both ends of the ferrule where it contacted wood,“just to make sure” of a tight fit.Next came drilling the hole for the tang of thefile. As Figure 4 shows, I chose a drill just under thesize of the widest measure of the tang at 3/4 of the wayfrom the pointed end. In this case a 7/64” drill bit wasappropriate for a 5/32” diameter file. I drilled to a bitover the length of the tang, inserted the tang of the file,stood the file on my workbench, and tapped the woodhandle with a mallet until a solid “thud” was heard,firmly seating the file.Figure 4. This photo shows the details.I made different numbers of grooves and alteredeach handle to be distinct. That way, over time, thefeel of the right file would match up with the correctchain saw.Initially I planned to just woodburn in the nameof the saw and the file size. However, I later decided toadd the model number of the saw. That way, when in arush and dashing off to the store for a replacement file,that handle would have all the information right there!Figure 5 shows 4 files. I made an extra for the big Husqysince it seems to be used sometimes from the garage,and sometimes out of my basement studio.Figure 5. Four files with different handles.Figure 6 is a close-up showing model numbers on2 of the handles. Two of the files, for the Gas Husqy andthe Ryobi Pruner, are hung on the garage wall so as tobe handy for sharpening. The second Gas Husqy file,and the Husqy Electric files are in the maintenance boxfor chain saws, kept in my basement studio.When the file handles were all done (and I decidedto not bother applying any finish) I turned to my twobowls gouges to apply the “Warren Carpenter AntirollingFlats.” First I set a gouge on the lathe’s bed andmoved it about to find the balancing point.

out to be up near the ferrule. Then turning the gougeover so the flat would be on the side opposite the flute,I used my belt sander and sanded a flat area about 4inches long and about 3/4” wide.Now I feel safe and smug about both my chainsaw filing situation, and my non-rolling woodturninggouges.Look out bowl blanks, I’m fully ready now!Figure 6. Two handles marked for a particularchain saw.That worked quite well and kept the sharpenededges skyward. One gouge had been used a lot morethan the other of the same type, so the metal part wasshorter. Yet, the second and longer gouge displayed essentiallythe same balance point, so I put a similar flatarea on it in the same place.Figure 7.
