What’s on your lathe?

My longest drought not turning this week. I had to get some projects done around the house and move some of my logs off the ground and under cover. Was able to get to my large maple log that I had covered up so decided I had to turn some today. Turned 3 of the 4 blanks today, cored all three, and wrapped the other one for later. Larger ones should finish 16” x 6”. Trying to save some of this log for hollow forms.

Howdy strangers. Post shoulder surgery and easing back into turning View attachment 75800

Hey Michael, did your shoulder injury affect your music? (I'm assuming you play, based on your avatar photo)
Last year I had an AC separation on a fall and after surgery and 6 months of PT I could get back to the piano and guitar (and woodturning). But I think my future as an accordionist is history (too painful to work the bellows). I did get a cello recently, mostly as therapy.

Ok, I'd love to know what kind of wood that is on your lathe. Stunning color and figure. Can't remember ever having a piece of wood that looked like that.

Well this one few apart a few times, I perused it and I think it will be nice when done !
Oh yes it’s cherry !🍒

OOF! Some internal cracks, that what's flying apart? I had a piece of wood, I am pretty sure it was Canarywood but not certain (it was never labeled, and even when I asked the guys at the woodcraft store I bought it from, they weren't certain, although their guess was canarywood as well), that had some pith in it...mostly centered, so for boxes I thought it would be fine. What I couldn't see from the outside, was that just in a ways from the outer end, a crack started, and ran through most of the internal length not far from the pith. Once I turned the first chunk round, a fairly large chunk just flew off, and I don't even think I had the tool on the wood. Just poof. That one was close enough to the center, that the live center on the lathe no longer held properly, it cracked through the bit of wood that remained, and the whole piece flew (not too fast, IIRC I was around 1000rpm) off the lathe and took some damage.

Second chunk I cut out of this block of wood (it was about a 14" or so long 4x4 spindle blank) I thought was doing better...but it, too, tossed a chunk when the edge of my tool caught a hairline crack I could barely see. Pretty sure it was the same crack, only it had angled a little farther away from the pith at this point.

I still have about half the blank left. I haven't done anything else with it...not sure what to do. I can't really even see the crack, its there, but very fine hairline. I think it runs through the entire blank. I may try to see if I can get some ultra thin (almost the consistency of water) GluBoost CA glue in there...maybe it will penetrate far enough down this crack to actually hold everything in place for the remainder. Not sure. Sad, because the wood is actually quite nice, and fairly colorful grain wise with some oranges, yellows, reds and even some slight grayish-blues.

If surfaces are smooth or can be made smooth (disk/belt sander, tablesaw?) you could try testing by applying a fast drying liquid. The liquid can seep deep into invisible cracks and can reveal the crack locations after that on the surface has evaporated, especially on end grain. Some use alcohol or mineral spirits but I prefer naphtha - extremely fast drying, leaves no residue, affects no finishes. Once you locate and mark a crack, yes, soak it with thin CA. Test again after turning a bit since the CA may not penetrate far.

I also use naphtha to reveal sanding scratches. Apply liberally, and for just a few seconds after the surface dries any sanding scratches may be revealed. Have to look fast.

Another way to test for invisible cracks is cut off a very thin slice on the bandsaw. Gently bend the slice and the wood will break at the crack. If I suspect the cracks are not deep, but simply shallow end grain checking, I might continue to remove thin slices until I get to good wood.

Deep cracks, or worse, ring shake, I'll either cut the wood into smaller useful blanks or throw it all in the burn barrel.

😭 I live in a darn nanny state!! 😭

No naphtha, no real mineral spirits, no VM&P, no toluene, no xylenes. I think even hexanes were, well, at least restricted. I think the list goes on. Sadly, not all of these are actually "banned" but the consequences of violating even just restrictions, like on naphtha, are strong enough that none of the manufacturers seem willing to ship any to Colorado. At least, I haven't seen naphtha or toluene anywhere for some time now. I could really use something to reveal sanding scratches.

I'll try alcohol, see if it helps reveal the crack more.

I might try the bandsaw trick. Pretty sure the top half of the remainder has the crack most of the way through it, but the bottom half, maybe not.
 
This cherry was given to me and is quite dry.
I won’t use ca glue on this type of separation, I have found that ca doesn’t alway have the strength of pva glues, but that’s my opinion no science applied ! Just in the field of carpentry. seems like there’s some good suggestion here.

It did indeed. I had a concert at the end of March and delayed surgery so I wouldn't miss it. It was tearing of the ligament and a burr on the ball that was tearing a hole in socket. Orthopod rasped down the burr, stitched the tear and laced a braid along tendon. I've been easing back, but two of my sons are learning bass also, another cello, and I have been using their practice time to sneak in some time on the fingerboard

David-You struck the motherlode with this super curly/ambrosia maple. I keep waiting for my tree guy neighbor to cut some down on a jobsite-I really need some of this wood!

Excellent!

Our middle son plays the cello and he and I have played some weddings for friends and such (with me on the piano).

I assume you know Edgar Meyer? His father started the strings program in the elementary school in Oak Ridge, TN. That's how my son got started in the 4th grade. I encouraged him to go for the cello (since I love the sound!) and he was one of the few who stuck with strings. (Did you ever hear a concert of Christmas music with over 100 fourth-graders with about 3 months of experience? Aaaa...!) I think what helped our son the most was findind a good private teacher - he studied for years with the 1st chair cello in the Knoxville symphony orchestra.

Edgar did something very kind when he visited Oak Ridge. He always spent time with the bass and cello players in high school and gave advice and encouragement! I think there were only 5 or 6 students still with strings by then. What a guy!

I played the bass for a while at Berea College in KY when they needed someone for the band for the college Country Dancers. I'd never touched one so I put scotch tape on the finger board so I'd not be too far out of pitch. No bowing, fingerstyle only. I even got to go on tour with them to places in KY and Ohio. The band was piano, fiddle, guitar, bass, and I forget what else.

I learned enough cello years ago to play duets with our son (we had several cellos by then) but haven't touched one for a long time so I'm starting from scratch. As well as the lathe, welding, and machining, my shop now has the cello, violin, guitar, cornet, french horn, harmonicas, melodica, and a new Yamaha electric piano. I can play as loud and poorly as I want and not bother the rest of the family! A friend gave me an electric bass but with I had to give that up - stretching the left arm was just too painful for the shoulder. (Another friend is threatening to give me a musical saw - the hardest instrument I ever tried to play!!) Fortunately for the instruments the shop has central heat and air...

This was our music room when the son was in high school. (Anyone interested in a bunch of midi gear?)

Have you tried looking up Ronsonol Lighter Fluid? Possibly at Ace Hardware. Its naptha.
