A COC's major rant about a minor problem

I appreciated your friendly responses to my requests for the size, form and pitch of the adapter hole in the body of a Nova chuck. So far no answer and by now I'm not likely to get one. I don't mean to be petulant, but even if minor consequence, the outcome made me wonder.

I believe the difference between products that are protected by closed trade secrets as opposed to open patents is significant to woodturners. Furthermore, I believe that just _knowing something about the materials, specifications, design and limits of the machinery and all the other products we employ in home workshops is reasonable and not a bad thing.

You may argue that someone who has no idea where the brake or accelerator pedals in a car go to can drive as safely and efficiently as if they did know. Maybe so, but _knowing as much as possible and that includes threads, about dangerous machinery doesn't seem much of a stretch to me although I can understand why others couldn't care less.

We seem to need to know all about the steel in our gouges, the bearings in our headstocks, the shape of our chuck jaws, the mechanisms in our speed controls.... Is it so contrary to want to know the threads in our Nova chucks or in any other machinery we use? End of rant.

Some jaws interchange between Nova and Oneway chucks. Are the threads in question the same? If so, can I know their specs whether I need to or not? :)

Mangiamelli wrote a piece on that. Seems you only have to defeat the safety feature on the Oneways.

But if you've got Novas, why bother? Nothing in the Oneway stable that you can't do better on with Teknatool.

I thought that if the adapter threads were the same, Oneway might be more open about divulging the specs. BTW. I'm happy with my three Nova Chucks.

Arch, this may sound like a radical idea, but why don't you just measure one? BTW, Teknatool never responded to my e-mail.

Tonight I received a cordial email including an offer to send a diagram and specifications of the Nova chuck from Roger Latimer of Teknatool. It is a most reassuring corporate attitude for all present or prospective Nova owners.

Thank you Roger.

Hi LD. Thanks for trying. Ranting right along, I didn't measure the threads for the same reasons I don't analyze the contents of many other products that contain some potential for injury: I am not competent to do so and makers usually have some responsibility. It seemed unnecessary to justify my question and ok to just want to know and to ask help from others who are more capable of making measurements.

A blunt micrometer, 60deg. National form thread gage, bifocals and yours truly aren't up to determining thread forms. I thought major and minor diameters and even pitch diameters and double depths would be easy for one of our machinists. I might be able to measure the thread pitch & lead, but then again I might not even know if the chucks are double threaded. :)

I'm sorry for the brouhaha. Let this thread (the one on rcw not the one on Nova) RIP.

It's been pretty interesting, while it lived.

Again, demonstrating the efficacy of the adage that the squeaky wheel gets the attention! As well as living up to "Fortiter in re!' Right on, Arch!!
