Hi,
I recently recieved two sets of blackwood turning squares for making A couple of R&R keyless flutes . The wood is beautiful!
Dave is offering the blackwood at a fair price, as it is very hard to find good instrument grade blackwood on the market these days.
He has also made a couple of steirling tuning slides for me, that are as “snug as a bug in rug!”
He recommends 4 to 6 months wait 
between the “roughing out” stage and the reaming stage, so I will have plenty of time to work on the design of the flutes, i.e.. new set of reamers, hole placement, etc.!
I will mame a couple of prototype Delrin R&R flutes to work out the kinks.
Just thought i would let anyone interested know that they were available.
Email him directly for prices.
P.S I am not getting anything for putting in a good word, unless he wants to send me a flute…

Have you found any cocus available for heads, barrels or repairs ?
Blackwood seems to be plentiful here , but not cocus .
Mr Jolson says blackwood flutes are better if you want to MAME them .
I don’t think that cocus is readily available anywhere. You can sometimes get it from Gilmer (located in Oregon). Their web address is www.gilmerwood.com . When I last spoke with them, they would only sell it as a complete log, which they would cut for you, but would not guarantee how much the yield would be. So you could be out a lot of money for an uncertain amount of wood.
It could be worth considering mopane as a substitute if cocus cannot be found. They are similar in density, appearance, and in the way they machine.

Al Jolson used to say the same thing, but he was talking about boxwood, painted black.

Jon,
You might try mangling some rock maple dowling instead, you can make a surprisingly good flute out of the stuff and it’s a lot less expensive than Delrin.

Hi Loren,
Delrin is $6 a foot, and it is already a round rod. Actually I don’t plan on “mangling” the delrin. I hope that I am beyond the mangling stage… 
I have made a couple of delrin flutes, and they play quite well.
The nice thing about delrin is that I can plastic weld the holes if I want to move them for R&D. This is a special plastic welder that works with hot air. Have to use a respirator, as delrin is nasty stuff to breath.
I can also match the material if I want remake a section. The nicest thing of all is that I can turn the whole flute in one weekend without waiting for it to cure.

I was hoping to find pieces of cocus for matching to cocus flutes -a replacement block or barrel ,say .
I am ashamed to find my name appearing several times in succession on the menu board .I must learn to contain myself !
Jon,
Whoops, sorry: You wrote “mame” and I thought you meant “Maime” so I wrote “Mangle”…oh, never mind 
I didn’t realize you had the technology to do the plastic welding - more power to you then, Delrin it is! Have fun!
Loren
Yes Loren,
we live in enlightening times! 
I have access to undreamed of technological advancements, such as you Mere mortals have only begun to tap…
