Waltzer Build

[Dwayne]

So I guess I better get this started :anguished:.
Nothing is finalised yet for this model (for one thing the wheels for the platform are giving me trouble) but here is the progress so far:
I have had the motor I intend to use one this model for a while but am a little concerned it might be a touch slow, I worked out the required speed by watching videos of full sized waltzers and working out they where doing about 12 to 15rpm so ordered slightly faster with the intention of controlling the speed.

drew up some required gears using freecad along with a mount for them all and have this

also pictured is my first attempts at the wheels but I am not really happy with them and would prefer something smoother running.
I have even test printed a car which I am quite pleased with seeing as the bumper around the top is my first time trying the sweep tool in freecad.

Interesting, I'll follow along if I may.

I'm in the early stages of converting a 1/50 trailer for a mate, into a fold out dodgem ride, to go with some other fairground stuff he has.

I'd got no intentions of making it working, but now you've got me thinking! :smiling5:

Feel free but its going to be a long build. Love the fold out trailer idea btw I did think of it for this waltzer but I think that is adding too much work to it.

I’ll follow as well. I loved the waltzers as a kid, could have stayed on them all day..... This looks like it will bring back those memories.

Amazing I took a picture of my latest attempts at wheels for the platform and noticed how bad the printing was. I knew that these filaments can absorb moisture but never suspected it could happen this quickly, the filament in question has not be on the printer that long. So I opened up a new reel and the difference is amazing

and now one with the tyre on (actually an O ring)

So tomorrow I will go to B&Q and search for some spindles for them to run on (nails :smiling2 and the holders are printing as I type this.

I've ever seen one...........big or small, I'm in. Rick H.

For want of a correct term I will call these next bits platform carriers. These are printed with voids to take the brass bit out of terminal blocks which are simply liberated from their origional packaging

I am using tiny eyelets for the linkages though I had to spread these open a little to fit the pins through as they where a bit tight.
I have only printed 2 for now to get a feel of how they work together and theres a tiny problem with the movement, I imagine on the full sized waltzers there will be a gimble of some kind that allows free movement in the required axis's. I think that opening out the holes may give enough free movement but if not I am imagining something involving a round bead might solve the problem.

Very intriguing. Rick H.

I have had a bit of a rethink with this project, Most full sized waltzers have 9 or so cars but when I started planning for my project I origionally thought the cars would be too tiny to spin at the size to keep them on the platform wedge so opted for 6 cars instead. However after doing a bit more research I realised that as long as the angles involved are not excessive they can overlap the neighbouring wedges by almost half and that just means making them high enough to miss.
So I am now going to make it with 9 cars which will make it much more true to life and so here is the new pinwheel hot off the printer

I hope to be able to start printing the platform holders by tomorrow.

I am thoroughly impressed by what you're looking to achieve with this. Far more ambitious than my meagre attempts.

Keep up the great work.

I seriously wouldn’t know where to start on this, so am thoroughly engrossed by your progress.
