I posted yesterday that I was stabilizing some corncobs using a hand pump vacuum from Harbor freight and would turn some today.
The material I used was a wood hardener intended to be brushed on made by Bondo.
I can fit 3 sets of blanks in a tall pickle jar which is then filled to the top with the solution.
THis jar goes into a Ball canning jar that I Rube Goldberged up a fitting on the lid to go to the vacuum pump.
The cobs were under the vacuum for about an hour last night and then hung to dry.
I had predilled the holes for 7 mm tubes so the soaking action worked from inside and out.
The pen I turned was meant to be entirely experimental.I tried to treat it as I would any blank but all the time I knew that it might blow out.
It is because of this that there are maybe a few shapes in the pen that I normally would not include in one pen.
It turned as well as a corn cob could be expected except it went a lot faster because I did not have to stop and stabilize with CA and no drying time beyond the initial time out of the pump.
About 18 hrs.
The solution for hardening is actone based si I would imagine I could brew my own using acetone and plexi as mentioned in this forum.
I'd like to say it came out "well" but as you can see in the picture that the cob is not green as I had colored it with a magic marker.
Once a coat of thin CA hit it the color scheme went out of whack.
That's okay I figure that there is no correct color for a corn cob pen.At least not this one!
