Had today off and decided to spend some time turning again. I mounted up decent size pc of pine log and started cutting it( pith included). I had to turn off a bit of the wood due to end cracking etc.....but it was going fairly well until i started hollowing it out. I saw some micro checks on the outside before i started but figured if i had sharp tools and took light cuts i could get it down to less than 1/4 thick....... Ok..... I was wrong...... I heard a loud pop when i was hollowing around the inside middle of the bowl. But, the bad thing was i was just a little less then the 1/4" i was shooting for and trying to go a bit thinner. I should have stopped at the original 1/4" that i was shooting for i guess- I knew the fissures were there (visible on the outside-very light - micro like). What caused the failure ?? i think either the micro cracks or cutting to aggressively or both !!!! Dang...... Anyway, I stopped the lathe and looked at the bowl and saw on each side it had blown out a chunk but didn't explode the whole bowl. So i put it on the bench and thought ahhhhhh well more firewood - live and learn and all that stuff you think about.......
Later on i thought what the heck, and put some CA glue on the other micro cracks.......let dry for a bit and finish sanded it anyway......then torched it and sanded it again....However i didnt sand the inside much at all due to the danger in catches with hands or with drill and the holes in the sides........i turned the lather speed way down and used 80grit and 100 to smooth out a bit and burned it to......
One of my kids friends really liked it so i decided to hurry the finish so he could take it home later.....put a few coats of Danish oil and late that evening i put a couple coats of spray laquer on it...........Salvaged it i guess and it is different with the holes left it with burned edges .........anyway the one kid loved it so what the heck........Pictures below are of the bowl unfinished and the inside had not been burned yet.....
Two Issue or Problems I have with this wood :
Last two pics were of a vase im doing for another friend that likes the eyes of the pith..............Problem is im not found of the finish at all.
The tear out in wet pine is horrible even with sharp tools, sanding takes foreever due to the tearout - I am rough turning a few more now and lettting them dry for much longer periods of time. But even power sanding the inside is no treat (due to shape and depth) when your trying to get passed some of the tearout.......any ideas let me know.......
I really like the look of the pith in the wood but would like to do something else in the future as far as the finish goes. The Pine im using is just light yellow looking wood - kinda boring ya know - but the pith in them makes them look really different. I thought of sealing and staining but im not sure that is the best idea either...........any thoughts for others ??? Thanks Dan
