Anglewinder gears in sidewinder configuration

[arroldn]

Can this be done? Attempting to get a certain ratio. Or will a 18.5 mm Spur match with the Slot.it 6.5 mm pinion or would the Sloting Plus 7.5 match with the 18.5 spur?

I have used a 32t Slot.it AW gear in a sidewinder configuration. The other gears have different hub placement and actual gear diameter - so I think the smaller gears such as 26-28 probably will not even touch the pinion.

You can use 7.5 mm NSR and Sloting Plus pinions with 18 mm Slot.it spurs if you want to extend the range of available ratios. That will only work in cars or pods that are meant to be used with 19 mm spurs, though.

Maybe you could give more detail regarding the car as this could help with suggestions.
Sidewinder gears can be used in an anglewinder position but I dont think the otherway round is to be recommended.

Maybe this is a crazy question, but what ratio are you hoping to get? How much of an improvement are you hoping to see by using an unavailable/in-between gear ratio? I used an in-between/unconventional gear ratio once to good effect, but there were only three gear ratios available at completely different ends of the spectrum. If you're looking to find an in-between solution between two readily available sidewinder ratios (and you can do a lot with pinion/spur combos), I suspect that your losses from an odd mating of gears will outweigh any benefits from using an in-between ratio.

^ They mesh well. The problem you run into is getting them to touch at all when you start using smaller diameter AW gears - IE 26-28t Slot.it

My GT1 RAA car has a 12t slot.it and 32t anglewinder gear in it at the moment in sidewinder configuration since I haven't gotten around to getting a 32t sidewinder gear. It meshes better than a 12/34 Sidewinder Slot.it combo I had in it previously.

The problem with the NINCO's you were using is the pinion being conical. If they weren't it conical, wouldn't be such a big issue. NINCO realized this and thus their move to flat pinions.

Would you call that a conical error?

As far as I have seen, most of the Slot-it/SCX/Ninco/Fly/Monogram/Scalextric gears use the same gear PITCH (50 teeth per inch?metric) and will mesh and interchange. Sidewinder and anglewinder are similar, but not getting FULL tooth contact is the issue. In the commercial car world of RETRO racing we use angled pinions with inline crowns as a standard speed trick for less friction even though standard engineering practice would call for full tooth contact, matching the angles.

TSRF use 64 pitch american style drag gears and Sonic and others have more diameters to trial and error a fit of mesh and ratio.

Thanks guys for the comments. I'm trying to get a 32 tooth spur to match with a 12 or 13 tooth pinion. It is going in a Fly F40. It currently has a 34 tooth Slot.it spur on it. But I did find a 14 tooth pinion so maybe I'll just use that. Was trying to get somewhere around 2.5

Slot.it 13 tooth pinions sound terrible. There are 6.75mm diameter 11 and 12 tooth Slot.it pinions if that is any help. I think that Slot.it anglewinder spur gears vary in diameter, so they can all be the same pitch. The sidewinder spur gears come in either 18mm or 19mm diameters and the gears do vary in pitch. With 1/24th commercial raceway cars you can move the motor to adjust the gear mesh so mostly 48 or 64 pitch gears are used.

I can recommend the "illegal" combination of an NSR 12 tooth pinion (#7112) with their 32t sidewinder spur (#6032) for Fly cars. Several of my Fly classics have been running that combo for years.
