G'day, Great stuff...! Wonderful to watch you doing this sort of stuff - it reminds me of watching my father when I was a kid.... Sadly, I didn't watch enough of it, nor pay sufficient attention, to be any good at doing it...; too afraid of making a mess of something and wasting materials, kinda thing. I encountered a weird thing last week, on the interface of the Automotive & Aerodynamic Schools of Design. A modernised "chopped" 1930s Open-top Ford Roadster was parked in the main Street last week, all shiny Chrome & hand-painted Pinstripe Decorative Flourishes, white leather Upholstery, with a modern shiny chromed V-8 Motor on full display - no Bonnet or Cowling Sidewalls. The full "Hot-Rod Look", kinds thing. And instead of a conventional Axial-Flow "Radiator Fan..., designed to pull air in through a Disc of Helically-pitched rotating Aerofoils...; there was what appeared to be a Centrifugal Impeller - running bald, bare, Flinging Air in all directions Radially ; Due to the absence of a "Snail-Shell" Housing Surrounding the device as is "normal", placed so as to collect and direct the manipulated Out-thrown Airmass.... It bewildered me..., so I whipped out my Potato & captured a Video ; Titled, "Shiny ; But Not A Fan...!" Backtrack me To my Uploads to see Possibly one of the weirdest Airscrew Substitute Devices which anyone ever succeeded in manufacturing and selling. It must be actually functional..., or it wouldn't be on the Road ; but I can only surmise that - with no Bonnet nor Cowling, then the Centrifugal Impeller apparently successfully "Digs a Hole in the Air, slightly behind the Radiator Core..." and thus when the motor is running while the vehicle is stationary - Half the Air being radially redistributed has to be sucked in from the Front..., through the Radiator Core....(???) ! "AEROFLOW" is the brand painted on the Hub - so, business ecognomics suggests that it must "work" ; but, Ye Gods (!), it's the ugliest 'Excuse" for an actual Airscrew that I've seen for a long long time. Please free to backtrack me, to share in the spectacle...; it took me a day to thunk it through and imagine how it could possibly be sufficiently Functional As to be in Production ! Such is life, Have a good one... Stay safe. ;-p Ciao !
@FlyingForFunTrecanair Thanks ! Yeah, it's not at all what I expected to see there... Too weird to not share, kind of thing. Cheers ! Stay safe, ;-p Ciao !
Very envious of your practical engineering skills! And there's something about that flaring flame as you braze that echoes 'ancient man' smelting. Don a bear-skin next time! But seriously, an absorbing progression.
Brazing is decidedly old-fashioned but so useful; TIG welding would probably do the job as well but it’s rather soulless, much like electric cars and alcohol-free beer 🤣
The mounting plate pivot bolt is very close to the centre line of the 2 shafts, making tensioning a big movement i.e. the slotted hole may need to be slotted quite a bit.
19:13 : ) I do hope the metal around the keyway will be okay, having been annealed. There's lots of meat there, rhough - the mag exerts a pretty continuous load, too.
@@Del350K4 The metal to metal fit of the taper should do most of the work, the key is just there to line things up. The sprocket wheels are softer than Walter Brown and might wear out in minutes!
@FlyingForFunTrecanair I knew you 'd have thought about it and decided it was fine. I once had a 400cc single cylinder Yamaha motocross engine which snapped its flywheel magneto (a misnomer, there, but that's how Yamaha describe it) Woodruff key. I had one for a Bultaco and (I was young) I naively slimmed it down just a tad with the flat of a cutting disc in a grinder. I had the sense to keep it cool as I did the work, and it slotted in famously. Greatly cheered, I bolted it all back together and started the engine. It ran fine, but as soon as I rode the bike in earnest the key sheared so nearly that, upon inspection, it appeared to have been machined flush. And that's how I found out about case-hardening.
Fresno Air Parts (California) is great for Bendix parts. Reasonably priced. I rebuilt my two mags for my Aeronca and then found out that they sell brand new ones for $600 a piece. I couldn't resist and they are beautiful. I realize that's beyond the scope of your project. But just in case.
Lovely video as usual, thanks. I would question the stiffness of your mag bracket however, firstly the 1/8” mild steel will probably flex quite a bit with the heavy mag mounted on it, you might get a nasty resonance at certain revs. I would make it thicker but I would also pick up on three engine bolts not two, as they are not in a straight line and would stiffen the engine mounting quite a bit in addition. You could still use your slotted chain adjuster but would need to slot two holes instead of one.
@@robertfack3082 All fair points. There are four bolt holes on the bottom of the magneto as well, so it can be bolted to a table style mount. Once the timing is sorted, I might well bolt through one or more of them with a steady bracket. I had the mild steel, it was lurking under the bench. You know what these jobs are like, sometimes you have to make something and then design the Mark 2 version! Next one might well be alumanimanum as there’s no welding needed.
@@loomisgruntfuttock I’m actually very fond of our friends across the channel and certain figures from history are a tremendous seam of humour. Did you know that France adopted the millimetre as a standard measurement as it made Napolean’s todger appear to be bigger?!
Bloody good show!
Looking forward to it running I agree about chain drive: loved my XK engine...

When you said Lucas my heart almost stopped.

@@FlyingForFunTrecanair At one time Lucas made refrigerators. That was the start of warm beer.
@maryhines322 🤣🤣🤣
Very interesting to watch and calming to boot. Time for a wee power nap... Pietenpol power...
I have that effect on people 😂
I particularly liked Cardboard-Aided Design 😀
Me too!
Great engineering.

I just took a look, what a curious fan? More like an air brake!

I’ve extended the slot, seems to have done the job.
@@chriskiwi2601 I ended up turning the bracket upsidedown so the slot is close to the centreline and the pivot above 👍🏻
