luvdunhill Posted January 5, 2014 Report Posted January 5, 2014 (edited) That is possible here that it is a way to dry the wood, but it was done with hazardous chemicals and definitely used to beautify the material. The term is fumed and I am pretty sure there isn't much heat applied, if any. Hence the appeal to the woodworker and chemist Edited January 5, 2014 by luvdunhill
guzziguy Posted January 5, 2014 Report Posted January 5, 2014 It looks like it's wood "smoked" with ammonia fumes: http://www.djmarks.com/stories/djm/Fuming_Wood_47692.asp http://www.google.com/url?sa=t&rct=j&q=&esrc=s&source=web&cd=2&cad=rja&ved=0CDQQFjAB&url=http%3A%2F%2Fen.wikipedia.org%2Fwiki%2FAmmonia_fuming&ei=D7TJUvGtHZHxoATJjYLABw&usg=AFQjCNEm6Gvecy_2dsoKVMe0IROfVTfIUg&sig2=_qFWAlEUImkcrCAETkVaXw
kevin gilmore Posted January 5, 2014 Author Report Posted January 5, 2014 I am certainly up for that. No problem with the chemicals, and lots of extra fume hoods that I can seal and then evacuate safely. Great for oak and such, but that seems boring. need to find out what it is going to do with my favorite hardwoods. Probably only one way to find out.
luvdunhill Posted January 6, 2014 Report Posted January 6, 2014 Sweet! Boxwood is the only one I have seen and it was beautiful.
kevin gilmore Posted June 3, 2014 Author Report Posted June 3, 2014 because tyll's kgss absolutely needed a wood knob, I sent him the one I made out of Arizona desert ironwood. Which left me without one. So I had to make one, and I made another ebony one. black and white ebony and snakewood hopefully tomorrow. http://gilmore.chem.northwestern.edu/knobs5.jpg
morphsci Posted June 3, 2014 Report Posted June 3, 2014 Cool. I love desert ironwood. The handle of my Randall is made of desert ironwood. Not sure if it is from Arizona.

luvdunhill Posted June 4, 2014 Report Posted June 4, 2014 I have a bit of rattle in my knob and was wondering if anyone had a solution (… stares at swt61 …) I am using the Keystone panel bearing which seems to be comfortable with a 0.25" shaft and measuring that same shaft on my micrometer is amazingly 0.250". The shaft of the knob is 0.240", so we're talking about a 5mil gap. Ideas: some sort of adhesive teflon or even teflon tape? heat shrink (probably a dumb idea) some part buried at mcmaster-carr that fits the bill perfectly?
kevin gilmore Posted June 4, 2014 Author Report Posted June 4, 2014 ball bearing from the back make sure no one pours water over the thing 1
luvdunhill Posted June 4, 2014 Report Posted June 4, 2014 Seems a bit much. I think I will try Teflon tape first. I will report back.
swt61 Posted June 4, 2014 Report Posted June 4, 2014 The problem of a shaft that fits loosely into a hole, is one I've had exactly zero experience with. Teflon tape is going to be very difficult to keep in place, while fitting the knob onto the shaft. I would try some masking tape, as I think it'll hold onto the shaft better.

luvdunhill Posted June 6, 2014 Report Posted June 6, 2014 The Teflon tape seems to be working. The problem is that it isn't super durable even after 10 or so layers it took to get the right diameter. It worked perfectly for a bit and now has slight rattle.. it's like the tape is compressing with use. I will leave it for now I guess...
