Topic tags/keywords: lathe turning

I’ve got some small green logs that I would like to use to turn some tool handles, specifically a set of screwdrivers.
I’m not real familiar with turning green wood and want opinions on the best way to proceed.
Here are the options I came up with, but perhaps there are more.
1. Seal the ends and wait a couple years until the wood isn’t green

2. Cut the stock down to rough blanks and allow to dry

3. Turn stock while green to its rough shape

4. Turn to final size and form and hope for the best.

I’ve seen some info on using the microwave to dry the wood, would that be an option with option 3 or 4?
Anyway, I’m curious to hear other’s thoughts on this.
Thanks

Turn to rough shape while green, put in a bag with the shavings, and wait. Weigh occasionally to see when weight stabilizes, then finish turning. There is also Pentacryl, a treatment for green turning that I have not tried yet.

Don’t know diameter of you green logs, but if you can saw them into 2 or 2 ½: square blanks perhaps 10” long & end seal will reach EMC lot faster perhaps few weeks to month or two. You don’t say when those logs were cut down, but don’t be surprised if those square blanks become distorted as they dry, if they bend & distort you working with reaction wood. Reaction wood dries different normal wood but may have to square up ends before turning.

If turn rough turn freshly cut wood might end up with lot of crack wood!

Good luck with it.

Rough cut blanks green. Do not leave the pith in the blanks, ie if you want 2” blanks the log needs to be at least 5”, but bigger will work better. You can leave them square or turn round, but leave not less than an extra 1/2” in dia for warp. Green wood can be dried in microwave. If blanks are to air dry seal the ends – wood glue is the best sealer I have used.

Sounds good.
The logs are 6-8” in diameter, so I can split them down and avoid pith.

For sealing, buy a block of paraffin, heat in a double boiler, and dip the ends. That is how commercially sold blanks are treated. And the wax is cheap.

Don’t know if own a band saw & simple band saw sled but could add little more interest by cutting into slabs. Then make another simple sled so can cut those blanks on the slant or biases.

This how processed pen blanks here which cut 6” long by 1” thick gave enough to turn pen kits requiring 3/4” blank. Have done a lot of blanks like that with different species.

Figure 4-3 characteristic shrinkage helps understand what board might look like after processing. Normally don’t worry about pith unless turning bowls or hollow forms. Have turned few vases with pith in them thou which posted on my project page..
