SlotsNZ Posted January 16, 2025 Report Share Posted January 16, 2025 (edited) Hi Greg, thanks for your continuous contributions to the hobby. - A small suggestion that may help you. I have been using a discreet browser called DuckDuckGo - I use the apple App, but there is a website, so I can now embed videos again. See your link copied to this post. And I think it IS an issue with this forum software, - combined with certain browsers - something in cookies. Various of our club members in HBMRC have assorted issues trying to post or embed pics or videos. Duckduckgo seems to be a workaround Curiosity - What diameter are the grinding rollers/sandpaper cylinders? And what grit size do you use - couldn’t find it in your pdf document.

I include 120 with my machine, as it's a good middle ground that cuts efficiently without deep grooves that lower grits can cause. It's possible to get the sleeves in 36, 80, 240, and 600 grit in various kinds of abrasives. I usually include aluminum oxide sleeves, but you can also get them in ceramic and zirconia, though not in all the same grit options. 1 Quote https://www.printables.com/@MrFlippant Link to comment Share on other sites More sharing options...
MrFlippant Posted January 23, 2025 Author Report Share Posted January 23, 2025 Since RevoSlot has made 3mm axles in 1/32 cars a common thing now, not to mention all the 1/24 cars that use them, AND the fact that 3mm double flanged bushings that fit into regular 3/32" bushing clips don't exist (afaik), I've done a simple printable version. These will be included in my kits from now on, as well as a 3/32" version, as many new to the hobby who get my machine don't have spare 3/32" bushings to use with their slot.it and other cars. Note that, due to the variations of machines and material, you may need to get a reamer (or drill bit) of the appropriate size, or make adjustments to your flow rate or xy compensation in order to get a slip fit with your axles. They can be printed in any material and used with lubrication. I would not recommend filled materials, such as PETG-CF, as the abrasive nature might damage the axles. Here's a link to the printables page, where they've already been uploaded: https://www.printables.com/model/459450-gs-tire-grinder-slot-car-tyre-truing-machine-rsm I'll also be providing a bunch to Alan to sell via 132slotcar.us, for those out there wanting to convert cars with snap-in bushings from 3/32" to 3mm axles.

Greg, Scalextric Sport bearings were 3mm and double-flanged. I have a few pairs in my 'inventory' but I'd think they'd be fairly difficult to obtain at present.

Den Yeah, someone pointed that out on SlotForum when they were looking for some for their Tire Razor type machine. They got some, but it turns out the space between the flanges is more narrow than typical bushings, and would not work on their machine. If you have any, please measure that space between the bushings. I'm curious what it is. And, as you said, they're not readily available anyway.

big dennis Posted January 30, 2025 Report Share Posted January 30, 2025 Sorry for the tardy reply Greg ... The Scalextric Sport 3 mm double-flanged bushes (C8407) have 'thicker' flanges but on eye-balling them alongside a Slot.It double-flanged bush the flat area between the flanges appears to be the same. Obviously then the overall width of the Scalextric Sport 3 mm bush is slightly wider. I haven't any trouble with fitting them into the 'forks' of my Area 3 (aka Professor Motor) tyre truer. An alternative solution is to use Revoslot reducers (part number S-141) to 'sleeve' 3 mm wheels so they can be mounted on 3/32 axles. Of course these solutions have probably been made redundant for anyone who obtains your 3D printed 3 mm bushes. Den Quote Link to comment Share on other sites More sharing options...

Do you have a set of calipers to measure the outside diameter between the flanges? A full set of measurements would not go unappreciated, either. At this point, it's primarily a curiosity, since those parts are no longer homologated. ;-) Quote https://www.printables.com/@MrFlippant Link to comment Share on other sites More sharing options...
big dennis Posted January 30, 2025 Report Share Posted January 30, 2025 Sorry, Greg, but I'm about 120% low-tech. I've never owned a set of calipers, I've never had scales to weigh a car. Next time I go to our local track I'm sure our host will have all the gear needed to get the measurements. Den Quote Link to comment Share on other sites More sharing options...

SlotsNZ Posted January 31, 2025 Report Share Posted January 31, 2025 (edited) Being Ninco Xslot, “3mm” might be a moveable feast, look up N61403 on the Professor Motor site. They are single flange, so the width isn’t an issue. 51 sets in stock Edited January 31, 2025 by SlotsNZ Quote Custodian of many used screws (quite a few loose ) * Recovering Lapsed Slot Addict * Companion of other delusional slot addicts * Total kidder Link to comment Share on other sites More sharing options...
MrFlippant Posted January 31, 2025 Author Report Share Posted January 31, 2025 Highly unlikely to snap into the clips, but can certainly be used at the top of the axles bracket, which is designed to hold larger things steady. But, for that matter, pretty much anything will do that, including the Revoslot ball bearings.
