Rough Turning Boxes
I have a question about rough turning boxes. Does anyone rough turn boxes
from wood that not completely dry, then turn them again when dry? I am curious if the tennons need to be returned like bowls or if they are okay as is when turning them the second time. Does anybody do this with dovetail tennons? I have done a few with the standard tennon but wasn't sure how twice turning would work with boxes and dovetail tennons. Hate to find out it doesn't work well after doing a lot of them! Thanks! |

I used to use tenons and often had to re-round the tenon after complete drying. I used a hole saw in the drill press. After a cut was started I removed the center drill bit and finished the whole tenon length. Then I trimmed off the offcut with a heavy knife. Now I nearly always use dovetail recesses. Some woods do ok after drying and some really get oval making a poor grip with the chuck. I clamp the item in a jig with a hole in it the proper size and re-round the recess with a router with a 12 degree dovetail bit and a guide bushing. Works like a charm. -- Gerald Ross Cochran, GA An apple every eight hours will keep three doctors away. |

Rough Turning Boxes
I've done a number in wet black walnut. I had no problems once they
were dry. I don't think black walnut gets very oval, especially when your turning end grain. |

Someone brought to a woodturning club meeting, a lidded oval birch box. He had turned the box and lid from very wet wood to as finished surface as possible. He then let them dry and change from round to oval shape. As I remember, many of his attempts at this did not work but enough did to keep him trying. Anyway, by this process he avoided the remount problem entirely. |

Rough Turning Boxes
I rough turn all of my boxes, no matter how dry the wood is. They all
'adjust' to having the bulk removed. Turn the cylinder, part off the lid and bottom, rough out the centers (I use my hollowing tools as they are a lot faster than a forstner bit) leaving about 1/2 inch in the top or bottom, and maybe 3/8 inch thick walls. I tape the ends together, and let them adjust for at least a week. Then I will glue them onto waste blocks. I glued some on once before they had time to adjust and lost about half of them as the wood shrank, but the glue and waste block didn't. robo hippy On Dec 23, 8:15*am, Bill wrote: On Dec 21, 5:00*pm, "John Gbur" wrote: I have a question about rough turning boxes. *Does anyone rough turn boxes from wood that not completely dry, then turn them again when dry? *I am curious if the tennons need to be returned like bowls or if they are okay as is when turning them the second time. *Does anybody do this with dovetail tennons? *I have done a few with the standard tennon but wasn't sure how twice turning would work with boxes and dovetail tennons. *Hate to find out it doesn't work well after doing a lot of them! *Thanks!

Rough Turning Boxes
only wood turners want boxes with "pop" lids - no one else wants them that
way - literally everyone else wants loose fitting lids (not sloppy) that lift off with one hand. So, the worry about the wood changing shape (which it does, robohippy is right) is a non-issue if you make the fit that most want. "robo hippy" wrote in message ...
