rough turning peppermill blanks

I'm getting some new pepper mill stock but don't want to wait years to use it. I wanted to rough out some blanks, but I'm afraid that if the blank was to warp or twist that that the top would be off center to the bottom.

Anyone have any luck with roughing out blanks?

How wet is the wood? If you cut it to rough length and just turn it round, there shouldn't be too much movement. Especially if you re-seal the ends.

That bowl was perfect right up until that last cut...

I don't have a meter, but I probably should get one. (i have a $70 gift card to Rockler, any suggestions?)

I have some maple burl that was cut and sealed about a year ago and i'm going to be getting some pretty fresh flame box elder. I also have some birdseye juniper that I have for almost 2 years, but that is about 4-5" thick. I might try to resaw a bit to reduce some of the thickness, i don't need a 4"x4" pepper mill that is 12" high

I bought this one when only $10 and works okay.

If wood has been sitting around for couple years go ahead and cut to rough size and let it hang out for week or two. Same with fresh cut would rough cut to size and wait couple three months.

DV,
If your blank isn't really dry, they will warp after turning. I have had several do this when I thought the blank was dry. Moisture meter is on my list. The top will bind up in two spots as you turn it. I just take it apart, rechuck the bottom half between centers and take a very light cut on the spigot. Leave about 1/16" of side play if you grab the top and try to wiggle it side to side. Refinish the spigot with some lacquer and put it back together.
I do have one blank that I started to turn about 6 weeks ago. Box elder. It was completely waxed when I got it 4 years ago. I turned it into a cylinder with a tenon on one end. I noticed the chips were coming off more in ribbons than pieces. Slightly damp. The ends were still waxed, so I put it in a paper grocery bag along with some shavings and set is aside. I'll see what happens to it. My biggest concern is cracking with this size blank.
Better off to make sure they are dry. Cutting up kiln dried wood and reassembling in different colored layers is a nice way to make up some cool blanks.

Ever soak them in Denatured Alcohol?

I have read up on it a bit and would give it a try. Although I want to make some of the 18" and 24" ones so finding a container to soak them in could be a problem. I could get a 30 gallon drum, but that seems like over kill.

That got me to thinking about a similar item I was wanting to soak in alcohol.

My first thought was 3" PVC Schedule 40 pipe with an end cap glued on. It is omly moderatly effected by alcohol, but unfortunately, the glue won't hold up. Some of that roofing rubber (EPDM I think) band clamped for a bottom would work. Better still, if you have a seamless section of pipe large enough for the blank to fit inside of.
Or make a trough out of a section of gutter with two end caps caulked with SILICONE caulking should work also. Just some thoughts - no guarantees.

How long would you predict you would have to soak a blank?

Maybe a couple few days... or a week if I forget about it. I'm going to have to play around with it. When I do i'll probably try to have a moister meter and track the weight of the blanks. So maybe next year
