Thread: JAW IS ROOT CAUSE FOR MANY CATASTROPHES

The words "Burn in hell, spammer" sum up my position.

Sounds like an age old problem to me.... orbiting a project most call it today.
From Hand or Simple Turning published about 1870..... (Holtzapffel)
the work while under operation sometimes escapes or is thrown out of the chuck with more or less violence.

I believe almost all "orbits" can be traced back to "operator error" through either lack of knowledge, oversights, miss-judgements, overconfidence, not paying sufficient attention to well known hazards or proven "safe" techniques etc. Sure we are all guilty of any of those mentioned. All tools be it a lathe, chuck or hand tool will only produce what the operator is capable of producing, and be as safe as the operator's awareness of inherent hazards, skill in identifying them, knowledge and skill in negating the hazards & in using the tool. "A poor tradesman blames his tools."

The timing & trajectory of the "orbit" is rather unplanned of course .

Many turners laugh about orbits but in fact they are very dangerous occurrences to the turner and any bystanders and should never be taken lightly. The mass & speed of the "orbited" piece whether it is part of a chuck or the work piece dictates the damage caused but such "orbited objects" have caused horrific head & facial injuries to turners, even deaths.

"Orbiting" is a hazard that certainly has been known about for a very long time, since the invention of the first lathes then chucks. Holtzapffel in his "Turning & Mechanical Manipulation" series of books documents almost all of the techniques we still use today. One thing he hasn't described was the three jaw scroll chuck patent registered in 1862 by Austin F Cushman and later the four jaw scroll chuck which were invented well after Holtzapffel's time (d.1835).

So things do change and some times the benefit of a new invention may not be initially apparent.

Paul’s innovation offers a potential solution for turners who wish to further explore lost wood staved construction turnings – something that commercially available jaw sets do not currently offer, other than Cole Jaws & Longworth Chucks.

Sound technique and good maintenance is more the issue here - learning to use tools correctly and within the range of use they were designed for and keeping them in good serviceable condition. I think I would put much more faith in Paul's invention than many of the home made "Longworth Chucks" I have seen. I also see Paul's invention as a vastly improved "Cole Jaw" design with many possibilities through using various sub-jaw designs other than his initial design or the standard cole jaw buttons.

(ps I have no benefit what so ever in the success or other wise of this invention. I do like seeing innovation that improves safety for wood turners so I keep a very open mind and use critical judgement not emotion to appraise any new product or invention.)

Shame it was not introduced to us as a new product or concept, instead of a call to arms.

It's a bit like the Saw Stop guy and his attempts to get his safety device made into a mandatory fitting in new table saws.

The Saw Stop is a great idea, but the fact that the inventor has acted like a dick to try to force manufacturers to pay him a licence fee puts me off the idea of buying one of his saws.

If I ever do buy a table saw with a safety device like that, it'll be once his patent has run out or there are perform-alike patent-skirting clones on the market.

Interesting to see that Paul Stafford has not been back to visit this forum since placing the advert for his invention.

Just another self interested "hit and run" and "what's in it for me" new forum member.

Yep, and good riddance.

He might have a good idea, but after his method of introducing it, I personally wouldn't dignify it by even bothering to check out his patent.

As spam, I would have preferred to see this thread deleted as it should have been as soon as the facts came to light.

OK, I will now close this thread.

If Paul Stafford would like to reply to any of the above he can send me a PM and I will re-open it.
