gallery. <strong>The</strong>y were in cases andunder glass. Because <strong>of</strong> <strong>the</strong> glareon <strong>the</strong> glass I was not able to getany descent pictures <strong>of</strong> <strong>the</strong>m. <strong>The</strong>ycan be viewed at http://www.penmakersguild.comas soon as <strong>the</strong>yare uploaded to <strong>the</strong> website. I don’tknow when that will be but by <strong>the</strong>time this issue is published <strong>the</strong> displaypen pictures may be posted. Ifnot, check back periodically and youwill see some well done pens.That’s about <strong>the</strong> extent <strong>of</strong> penturningactivity at <strong>the</strong> <strong>2009</strong> <strong>AAW</strong><strong>Symposium</strong>. I had a great time. I satin on several excellent demonstrationsand hopefully learned a fewnew things I can use in my shop.SnakewoodI mentioned purchasing snakewoodblanks earlier. Snakewood isprone to cracking and for this reasonmany penturners, both <strong>the</strong> casualand <strong>the</strong> serious, shy away from usingsnakewood. Snakewood is one<strong>of</strong> my favorite woods and makesa stricking and beautiful pen. Ofcourse, <strong>the</strong> blanks need to have lots<strong>of</strong> those dark snakewood blotches.I very seldom purchase snakewoodunseen, except from vendors I knowwho only sell <strong>the</strong> best <strong>of</strong> blanks.Snakewood cannot be stabilized.Figure 7 is a picture <strong>of</strong> three snakewoodpens. <strong>The</strong> pens were not madeby me but I did repair <strong>the</strong> cracks.Figure 7. This is a picture <strong>of</strong>three snakewood pensHere’s <strong>the</strong> snakewood penstory about <strong>the</strong> pens in Figure 7.I received an email from a gentlemanin California who had threesnakewood pens. He love all three...and <strong>the</strong>y cracked. He contacted <strong>the</strong>maker and was told that snakewoodalways cracked and <strong>the</strong>re was nothinghe could do. <strong>The</strong>y could not berepaired. I do know <strong>of</strong> several snakewoodpens that have not cracked and<strong>the</strong> discussion to keep snakewoodfrom cracking will not fit here, evenif Mr. Holder allowed me to use <strong>the</strong>entire issue space for <strong>the</strong> discussion.Anyway, I was contacted about <strong>the</strong>snakewood delima and I told <strong>the</strong> fellowto send <strong>the</strong>m to me and I wouldrepair <strong>the</strong>m. He sent <strong>the</strong> pens to meand I repaired <strong>the</strong>m Now I have anew pen customer who owns several<strong>of</strong> my snakewood pens.How did I repair <strong>the</strong>m, youask? Well, if I told you I would haveto ..... Just kidding! Here is how Ihandle snakewood pens. I want <strong>the</strong>blanks to crack so I can repair <strong>the</strong>m.I have not had a snakewood pencrack again after making repairs.Knock on snakewood. A crackedand repaired snakewood pen isnicer than most any o<strong>the</strong>r pen. <strong>The</strong>repaired crack is <strong>of</strong>ten not noticeable.Follow along.First I drill <strong>the</strong> blanks and set<strong>the</strong>m on a shop shelf and forgetabout <strong>the</strong>m. I check <strong>the</strong>m in a fewweeks and see if <strong>the</strong> tubes will slideinto <strong>the</strong> drilled holes. If not, I ream<strong>the</strong>m with <strong>the</strong> proper drill bits andplace <strong>the</strong>m back on <strong>the</strong> shelf. I dothis for several iterations...maybethree or four. <strong>The</strong>n, I insert <strong>the</strong> tubesbut I do not glue <strong>the</strong>m. I trim andsquare <strong>the</strong> ends and rough turn <strong>the</strong>pens. Yes, you can turn a pen blankwithout <strong>the</strong> tubes glued inside. Justinsert <strong>the</strong> tubes and bushings andplace <strong>the</strong> blank on <strong>the</strong> mandrel.<strong>The</strong> bushings will hold pressureagainst <strong>the</strong> ends <strong>of</strong> <strong>the</strong> blanks andallow <strong>the</strong>m to be turned. I turn <strong>the</strong>mto about 1/32 inch larger than <strong>the</strong>bushings and to <strong>the</strong> final shape. I set<strong>the</strong>m on <strong>the</strong> shelf one more time andcheck <strong>the</strong>m if two or three weeks. Iream <strong>the</strong>m if needed. At this pointI glue in <strong>the</strong> tubes. Now comes <strong>the</strong>part that takes even more patience. Iplace <strong>the</strong> blanks with <strong>the</strong> tubes gluedinside back on <strong>the</strong> shelf and wait. Iwait for <strong>the</strong> blanks to crack. Sometimesit happens quickly and o<strong>the</strong>rtimes not so quickly. When <strong>the</strong>y docrack I move to <strong>the</strong> next step.<strong>The</strong> next step is <strong>the</strong> repair. Iplace <strong>the</strong> blanks back on <strong>the</strong> la<strong>the</strong>and do my final turning to <strong>the</strong> desireddiameter and final shape. NowI sand <strong>the</strong> blanks starting at 220 andpausing after 320 to collect sandingdust on <strong>the</strong> surface <strong>of</strong> <strong>the</strong> sandpaper.<strong>The</strong> dust is <strong>the</strong>n mixed with CA glueto make a CA/dust slurry. Usingslow speed on <strong>the</strong> la<strong>the</strong> I place <strong>the</strong>[Continued on Next Page.]More Woodturning August <strong>2009</strong> Page 21
