My Local club NQMP had a small Fathers Day Display at the Harvey Range Tea rooms 45ks from Townsville
I took 4 outboards 3 electric mowers and 1 electric (415 volt) chain saw

Hi Ian and ODK members,

There are historic buildings around Townsville?
What? More than twenty years' old?

Your display provoked some thoughts.

The first is that you have presented this great display.
Second, I wish I knew more about vintage outboards.
Third, a 425 volt chainsaw?
Fourth, "Long Steep Decent" - the story of my life.
Fifth: the electric mowers!

Your choice of these electrics is thought-provoking..

Your Tecnico represents Australia's first rotary.
The late model Sunbeam represents the only electric rotary that was
available in the 1960s - when the petrol rotary reigned supreme.
The Victa Electric represents the new-found-faith in electrics,
led by Victa in the 1980s. We have not looked back.

I guess "Watch For Slow Moving Vehicles" was a reference to my drive
Hope you had a great Fathers' Day Ian!

Jack

415 volt chainsaw?
Hi Jack
Yes that's right, used in sawmills
Ian

Yep, I've seen one in the Kauri Museum in Matakohe, NZ. Also made by Danarm, with about a 7-8 foot long bar! Used for breaking down the immense Kauri logs in the old days.

Found a forum thread with a couple of pics of that one; Kauri Museum

Hi Gadge, we'll that is certainly something that I have never seen before. A 3 phase powered chainsaw....Thanks for sharing the pics.
Ian, congrats on a fine display.....

And back CyberJack, great to see you posting again, and from tassie!

I inherited a 3 phase angle grinder some years ago. Unfortunately I promptly ruined it, by attempting an impossible modification, but it worked quite well when I received it. It was made in Italy, with an all-aluminium body, and was intended for long run-times and longer operating life than the conventional, commutator-motor angle grinders. It was probably 50% heavier than normal, which seemed reasonable given the advantages.

Aha,now you have tweaked our interest, what was the impossible modification you were attempting?

It's a sad, embarrassing story Deejay. I wanted a miniature flat-disk, horizontal-shaft grinder as a workshop machine, and I wanted it to be free. So I decided to attach the 3 phase angle-grinder to a frame. On one side it had a tapped hole for the lateral handle (it was a full-sized 9" angle grinder, and they always have lateral handles for reasons which become obvious the first time you pull the trigger on one and experience the gyroscopic precession as it accelerates the grinding disk). However I needed another mounting point approximately horizontally-opposite that handle. There was an unused boss on the housing in the right place, so I decided to tap it and screw in the mounting. Then a small error crept in. Naturally I was doing this without dismantling the grinder - it was a very small job. Instead of bolting the grinder down to the table of the milling machine and feeding the tapping-sized drill bit by moving the table up, I held it in position on the table of a large vertical drill. Murphy's Law was in operation: the drill bit immediately grabbed the aluminium housing of the grinder, and pulled it upward so that the drill bit penetrated the housing rather than stopping at the bottom of the boss. Phase 2 of Murphy's Law also applied: the drill bit dug well into the windings of the grinder's induction motor. My ambitions do not extend nearly so far as to try to rewind a miniaturised 3 phase induction motor, so I flipped the whole machine into the nearest skip.
