Dental drill turbine shaper

Small hand operated shaper

In my Album there is a picture of a very small shaper. This machine was given to me by my friend Howard who lives in Wagga Wagga NSW. Howard is a collector of automatic lathes.

Anyway Howard was the mans workshop assistant repairing the old belt drive dental drills. We are still not sure of the mans surname but he lived in Hornsby a suburb of Sydney NSW. After the mans death his wife sold his patents to a US company who immediately crated all the workshop tool and machinery and had them dropped in the ocean in very deep water never to be seen again.But prior to the inventor passing away he gave the shaper to Howard as a gift of friendship. Now Howard give it to me and I am trying to find out its history and who made it.

Anyway if you try to find out who made the first air turbine dental drill you will be told the US did but it is not the case. I will get Howard to come on so he can tell the story.

Regarding the electron Microscope I was approached by a physicist from NSW university to make some parts for an electron microscope that he designed the process. The actual physical unit was still a blur so he would ask me can I make an item which was possible, and I redesigned it to make it fit the vacuum chamber. On completion of the unit which took 2 years the microsscope worked well and that was the unit that found the dust mite in air particles.

I can give you the peoples names but I will hold that back.

Your shaper looks like an Adept

Larry,

Thanks for getting this one rolling

… I look forward to hearing more from you, and from Howard.

… and is probably just what Ian needs for this job

I have a No 2 Adept but I'm pretty sure that's a No 1 Adept.

This is one of these things that passes the ME community bye

No-one seems to be interested

No-one asks, how did he do it?

Would anyone care to hazard the methods employed to achieve this objective?

(On a Adept Number 1 too

50+ years after the first jet engine and not one single individual in here asks how this guy made a turbine on a hand shaper

… If it's not a choo-choo then who cares…

"The small shaper in my album is the machine that made the first turbine for dental drills and I will insure this machine goes to a museam. By the way that small turbine in my album is a axial flow jet turbine I am developing for my model DC10 which is somthing I was told could not be done. It is still a work in progress and run at 120,000 RPM."

Is the ME magazine interested perchance?

Maybe an article on making tent pegs would be better…

And can you PLEASE try and pull an article from the guy in this thread , Larry Coleman

Books can never give you what these guys knew

[Carl Wilson 4Participant @carlwilson4]

Hell will freeze over before you get an article on a gas turbine in the ME.

[JasonBModerator @jasonb]

I seem to remember articles on gas Turbine powered locos

[Michael GilliganParticipant @michaelgilligan61133]

Ady,

I can understand your enthusiasm … But I did ask Larry to start this thread specifically for him and Howard to tell us about the Dental Turbine, and the Electron Microscope.

Edit: Given what Larry ha told us so far; this timeline suggests that John Patrick Walsh may be a person of interest.

Can you tell me when this was, and if any technical details or photographs of the actual turbine, compressor or combustion chambers were shown?

[Ady1Participant @ady1]

I was on the sauce last night so feel free to ignore/delete anything I said

tsk tsk tsk

Hi Carl

> Hell will freeze over before you get an article on a gas turbine in the ME.

What on earth makes you say that?

The index lists 119 ME articles on gas turbine, dating back to 1905, including many about the GTBA and a four part series on building the original Schreckling turbine.

Hey lads

Lets not get into a frenzy over a 60 mm turbo fan jet until I put a fire in its belly. I am having trouble with the donut or combustion chamber. A friend of mine who is a turbo charger expert for truck engines is doing the shaft balancing. Fitted with ceramic bearings to withstand the heat and rpm's we have a good chance of actually getting it to run. The funny part about this little device is if I can successfully get it running it will be the smallest and first miniature axial flow jet ever made. At the moment it looks promising but I am not scared to give it a go.

Now back to steamers you will see in my album pictures of boiler plates for the L20 traction engine which I have completed. The reason I have made dies for these plates is to make them available to less skilled people to help them get in to the hobby and down the track hopefully be able to produce boilers complete or in kit form at a low price. I also have dies to manufacture 5" dia plates.

Now does anyone know anything history wise about that Theil filing machine because I have been told they are very rare. The auto feed really has me tossed. Auto feed what ? That picture of the counter weights should give some idea of the mistory and it seems to conect to nothing. The only thing I can think of it should have a cable conected to a pushing device on the table.

In that case I retract my previous ill informed statement.

[Neil WyattModerator @neilwyatt]

I should have been a bit less uptight, Carl, and remember that every reader has their own perception of the magazine, and sometimes two people's views would suggest they were talking about completely different publications!

It is surprising just how often it has been covered, but not for a few years. I have a 1940s ME that covers the theory with respect to a theoretical plant layout for a stationary 'power station' type installation with no obvious resemblance to a 'jet engine'.

There has been a little debate about the 'experimental' in 'model and experimental engineering' (in context of the magazines, not SMEE). I think there's plenty more fertile ground for experimentation, and not just in new technologies.

Neil

[Michael GilliganParticipant @michaelgilligan61133]

The patent that I linked, this morning, makes very interesting reading … although the "patent" style of writing is pretty hard-going [as is so often the case].

For the benefit of anyone with the patience to read it … I would just mention that, on line 32 of column 2 in the text; the word "construction" should [presumably] read "constriction".

Give it a go … it's worth the effort !!

Not a problem. We are all apt to be a bit uptight at times, me especially these days. Your comments on experimental engineering are interesting; I am a member of SMEE which bills itself as The Society of Model and Experimental Engineers. Their newsletter always makes interesting reading, and the dedication of the core membership is beyond question. That said, there is very little "experimental" going on. That is most probably due to the fact that nobody has ever written an article for the journal on anything that might fall into that category. This is no doubt due, in no small part, to the fact that the average steam engineering enthusiast, or what might be loosely termed "model" engineer, would have little interest in such things. And of course the vast majority of SMEE members fall into this category.

So, we are a bit like Great Britain and the United States – divided by a common language!

And let's not forget, when Schrecklings How to manual was first mentioned in ME as a book review, the reviewer questioned mockingly the use of a fabricated plywood impellor for it. Pity he didn't bother to read the design philosophy AND factor of safety calcs. before making derogatory comments.

It wouldn't be ME without a bit of sniping between different ideas going on…

[DuncParticipant @dunc]

• Well, I'm not going to tackle the who made what first part but I recall using a "Borden" air rotor while I was a dental student in the early 1960's. The school (U of Toronto, Ontario, Canada) was considered well ahead of its time by introducing the high speed turbine for restorative dentistry to undergraduates. Now, of course, it is strictly de rigeur.

Given this context, it must have been one of the earliest (if not the…) available commercially – at least, in North America.
