Thanks ta0!!! Gonna need all the help I can get on this one, so if you've got any relatives or friends with only a mild curiosity in spinning tops, this might be the way to grab their attention for good. Under 48 hours until launch!

Here's a preview of what'll be available - straight from the actual Kickstarter page. Kickstarter doesn't let you "buy" multiples of a single object, so I've tried to design larger packages which people will want. Remember that backers choose the shells they want at the end of the campaign using the standard Kickstarter backer survey. That's important, because more designs will be unlocked as we gather more funds.


I think this is the first Kickstarter for a project like this. That's a real scary thought.

I was expecting them to do better than 102 backers. They raised 2.7 times their goal of $5,000, but that was a modest goal considering the unit price of $125+
I believe they partnered with a company that was already fabricating the levitating platforms (which you can buy for $50) so that takes away much of the developmental cost.

Oh yeah, the guys who made the hardware for the levitating plant kickstarter... Fair enough. Well I'm glad there was something about it. Otherwise, even with the money they raised, I couldn't imagine too many sandwiches being made before they had to go back to work. It's amazing how much a new product like that can cost to develop.

Lube Tests

I had settled on skin oil as being about as good as any lube when developing Euler discs.  I discovered it accidentally when encountering 2x variability in run time which turned out to be due to clean mirrors vs those with some skin oil.  Here's my record 5:54 run.



Tops are different, so I tested decay rates at about 500 RPM with different lubes.  Once again, skin (forehead) oil proved about as good as any.  I had learned with the Euler discs that an extremely thin layer works best.  I touch my forehead and then touch the mirror, leaving a thumb-print.  Then I spread it, wiping hard with the side of my thumb or finger.  I hard repeat wipes, each time at right angles about 5 times.

I noticed that very thin slippery lubes had much greater decay, even when I tilted the mirror often to move to fresh lube.  I was using a top with .375" diam ball and it skated freely with thin lubes, giving me the impression that drag would be very low - but it wasn't.  Conversely, I tried some thick grease which damped motion and eliminated skating.  With forehead oil, there's moderate skating which settles down as the top self "erects" in one or two minutes.

One other good lube is thin, "Dow Corning 33 Silicone Lubricant".  It's much thinner than the silicone grease that I use to improve seals.  It's even a bit better lube than forehead oil.

Regards,
Alan

El trompo ha evolucionado a pasos gigantescos en los últimos años. Creo que esta propuesta de sistematizar este ARTE debe ser plenamente analizada y revisada, porque creo, que, debe ser llevada a cabo. Va a requerir mucho tiempo, mucha paciencia, mucha dedicación, mucha entrega, mucha calma, mucha erudición y no va a ser una labor de una sóla persona. Cuenten conmigo para ello. Contribuiré a este proyecto de sistematización.


Spinning top has evolutioned with huge steps in the last years. I believe that this proposal of trying to systematize this ART must be analized and reviewed carefully, because, I think, must be done. It´s going to require a lot of time, lot of patience, lot of dedication, lot of courage, lot of calm, lot of erudition, and it´s not going to be a task of only one person. Count with me on it. I willl put my contribution to this project of sistematization.

I've been assuming that aero drag is near zero at low RPM, such as 200 RPM.  Have you compared low speed drag, with and without, vacuum?  It won't be exact, due to lube variability, but perfect repeatability isn't needed.

Best,

Alan

I bought some coloured electrical tape today!!!





The bad news is that all the color except black has a lightly sticky feeling to it!  :'(
Anyway, I don't think there is much I can do another it! It's not life changing but less fun!

All my a lot used top will stay in black I guess!

Yep, I'm looking at all my tops now :) the grande are a bit painful b/c I know the weight right will move when I play so it's bit worth less to balence but still!
Stretch the weight ring just a tiny bit. Most TGs do not have this issue. I have 1 or 2 that did. Also if a TG that was smooth starts to shake after a drop, just wack it (gently) on the floor crown first. The weight ring will pop back into place.

Welcome to the board, lastcenturygames from France!

You forgot to post a link to your site: lastcenturygames.free.fr
You have a wonderful collection of antique games there!  8)  The Toupie Hollandaise tables are magnifique!

I hope you can come to the Marines Festival.

Hello to all, I'm new in this forum, i have two "toupie hollandaise" in my house :  one big (like a billard) and a little another one (Tantet & Manon).
I have a spinning top for toupie hollandaise (see picture below) , the caracteristic is :
- height : 6,5 cm
- Diameter : 4,5 cm
- weight : 85g

If you know a specialist, he can perhaps make the same ?

In my website you'll see another spinning top table.
Have a good week end

I will definitly need one/or more of these couples (translucent top + board)!!!
Fore sure add me as a customer for the next prints...
