You are most welcome. My mum used to say 'I am a mine of useless information', lol.
I used to have a similar horn on my Kombi but it was a bit low and unfortunately got smashed on a bump. They always bring a smile to peoples faces. Very appropriate for a cyclekart I think.

Thanks Mick. It felt absolutely awesome.
After this video, I reduced the toe-in and beefed up the steering rod bearings, just because.
Yes, it's a cheap copy "Klaxon" horn (under $25 delivered, on ebay). It comes in black and chrome plastic, but I painted it. They are loud! I discovered that the sound scales down a little and the "a-ooo-gaaa" sound slows down a bit, if you run them on 6-8 volts instead of 12. Another hobby I have is electric powered gliders, so I've plenty of old LiPo batteries - they weight almost nothing and don't self-discharge.
Now I have to pull the whole thing apart, to paint the frame. Then I can put it back together and get started with the bodywork and dress-ups - woo hoo!
Thanks for all your comments and suggestions, by the way.

Awesome!!!!! Always the best feeling when you get a project running.
Is that an 'Arooooga' horn I spy on the front? A 12V gel alarm battery will drive that pretty good. Was planning to add on to my cart to power the lights (when I get that far lol.)

Just gotta wait until I can work out the correct length

It'll be a cinch to extend that steering column - for example: by cutting the existing column and patching in the some pipe that has the same inside diameter as the column outside diameter, which can be bolted or welded in place.
Nothing like solving problems and making something take shape to get your mind in the right place!

Thanks. This was just a bit of scrap I had laying around. I need to try again using aluminium as ultimately I think steel would be too heavy. Unfortunately I've never really worked with aluminium. Whilst it is easier to form, it is also a lot easier to leave marks in and so is less forgiving in that regard. Plus you have to anneal it whilst working. Not a hard thing to do, but just another consideration that you don't have with steel.
I've collected many metal forming tools over the years many of which I've put to use making repair panels, but I've always wanted to have a go at building something from scratch. I've been following the work of Chris Runge for a few years now. ( https://rungecars.com/ ) I love the work that he does, very inspiring. Definitely a bucket list thing for me. Don't know if it will ever happen however as even building a cyclekart is a massive challenge lol.

You've got a fine result just with that rusty test piece (?). Great to have tools like that and use them well after all their years of use.

I'll post as much working sketches & photos, I've had to guess most of it but it's coming into focus slowly.

Simonism Twanging a chalked string on to a sheet of 5 ply makes a good layout line (if straight line will do) curves is a different story

Can't wait to see how the build progresses. I'd love to build a 3 wheeler one day so I'm very interested in how you go about it.

Impressive and inspiring. It seems to be coming together very nicely. Such neat and precise work puts my rough kart to shame.

Great work Geoff.
I think everyone has officially overtaken me with their builds. I really need to get back onto mine.
Watch the chain path with those cross members too. I overlooked this with my chassis and now have to modify my chassis.

This is the last of the main parts that I need to start building.
Geoff Moore
2022-03-24 08:10
Exactly. I’ve already started tonight.

Well done mate. Keep up the good work.

That's not a bad price. Making good progress too.

For anyone who's thinking of doing this, you can cust these ribs of with a standard wood saw, then give them a quick clean up with a flap disc. Much quicker than using a flap disc for the complete removal.

The vague idea I was trying to flesh out was along the lines of a pair of gears on the swing-arm pivot one side chain from motor and the other chain to wheel hub. That would take better engineering skill than I have and be quite bulky, unsuspended axle is much more compact and simpler. I'll just have to put a bit more padding into the seat.
Morgan appears to use a CV joint pivoting on the same plane as the swing-arm.
Probably when I have a kart built I'll be better able to see a solution.

Not sure how important the suspension is on a 3-wheeler and what impact it has on handling. Generally with 4 wheel cyclekart builds the rear suspension is omitted as being superfluous.
Not sure how Morgan did theirs but obviously a bit different with the motor in the rear. I'm guessing they must have had some kind of trailing arm setup.
Rear suspension could be as simple as mounting the entire engine + torque converter + wheel + axle on a subframe that pivots on the rear of the main chassis. Basically like a giant hinge in the chassis just forwards of the motor. Like a giant trailing arm that contains the motor too - much like a Vespa or Lambretta

Thanks, the picture is building, rear suspension might just have to wait for version 2, between Mick and yourself I can see the simpler solution.

(Mainline)Mick - here's another photo, in case it helps the imagination. This is where I'm up to - working it out as I go - no plans. You can see how the base plate of the torque converter offers 12 different positions (not all of which may useable because parts of the engine could be fouled, eg, the tank). The black hatching marked on the base plate shows the strengthening ribs that I have to remove, to allow the chain to have a clear line from the output sprocket of the torque converter to my 60 tooth sprocket on the axle (plus I've taped up the bearing of the output shaft to stock crap going into it). Like Mick (I think?) I have yet to cut the keyways in my 25mm axle stock.
Simon : Have fun!
Mick Percy
2022-03-21 21:36
I struggled with this too. It'a s lot easier when you have the motor and torque converter and can lay it in the chassis. The Torque converter can actually be bolted on in a few different orientations too so you can have the axle forward or behind the engine.
This photo might help - https://cyclekarts.com.au/pages/brooklands-bentley/photos/298-img-9144
Also worth noting that here I've flipped the torque converter so that it faces backwards instead of forwards. It will actually get installed the other way around so that the engine is behind the axle. If you flick through the album there's a couple of other photos showing how the torque converter bolts up.

thanks, I'll keep at it

If it's true that there's nothing new under the sun, then you may be able to find some illustrative pictures/videos/plans on the web. Good luck!
