G&S Tire Grinder Provides a Cost-Effective Answer for Basic Truing Needs

In addition to creating and hosting the weekly Worldwide Slot Car Chat, Greg Gaub continues to benefit our hobby community by developing a number of useful 3D printed tools and accessories - most all of which he provides as free .STL files on Printables.com for users to print for themselves. In addition to helpful tools, Greg has created a unit that can convert almost any light scale into a magnet marshal, a multi-use setup block, and lots of other cool stuff. Greg's latest creation--which he developed withthe help of Dennis Samson and Giacomo Verlini--is a cost-effective tire-truer that will meet the basic needs of many slot car hobbyists.


Available as a complete, ready-to-use unit, a DIY kit with all parts included, a 3D-parts only, or as a hardware-only combination - the machine is intended to be a "good enough" machine to get casual racers started with their tire truing needs.The basic features include:

- One motor turns all axles
- Only two screws to remove/replace the entire grinding assembly for different grits
- Screws beneath the ball bearings to adjust parallel
- Spring loaded axle carrier to allow "grind and release" truing methods with ease
- Indicator knob for precise repetition of tire diameters as needed
- Consistent tension of o-rings due to double-pulley design
- O-rings can easily be moved side to side to accommodate various axle configurations
- standard 1/32 bushings snap into axle carrier, but V-shape still allows smaller or larger bushings or bearings to stay in place
- Distance between sanding drums accommodates most 1/24 and 1/32 wheels/axles
- sanding surface cannot contact axle pulley/o-ring
 
More information about the Grinder can be found HERE.

"Figuring" it out - Making Your Slot Car Track Come Alive

If you’re creating a scenic slot car track, there’s one thing you can add that will really bring your layout to life—and that’s adding some people. Whether it’s dozens of figures to populate a grandstand, a busy pit crew, some vigilant track marshals or just spectators wandering around, adding figures to your track really adds a lot of fun detail that can can look good and even tell a story.

Expert modeler and figure caster John Kit shows off some famous race car drivers.

For many years, the selection of figures that would be applicable to a slot car track was pretty sparse. Scalextric, Monogram, MRRC, Strombecker and Carrera provides very familiar (and limted) poses that could be placed around a track. While there were a few other options available, like a few metal cast figures and the inevitable Airfix/army man conversions, the available choices were mostly of vintage types—with 1960’s era Racing helmets and bareheaded pit crews, watched by spectators in old-fashioned clothing. Even the TV camera crews looked like something out of a 1950’s television studio. If you were modeling a modern track, it was a little anachronistic.

In the 2000s, things got better, as Carrera, Scalextric and a few other manufacturers updated their figures to more modern-looking examples—with helmeted pit crews and fewer spectators wearing mid-century era suits and ties or dresses. While it was an improvement, the prices could be pretty steep. Some advanced modelers employed old school resin casting and conversion methods to great effect, providing some extra variety and unique poses they could use on their own track.

You'd have to admit these Carrera figures are an improvement over the old stuff :-)

In recent years, however, the advent of 3D printing has caused an explosion in the number and variety of poses available to the modern track builder. Today one can find literally thousands of varied spectator poses as well as a wide variety of pit crews, drivers, track staff and many other useful types. These figures can be purchased painted and finished or unpainted, depending upon your preference and skill level. For those who own s 3D printer, there are a wide range of choices available in ready-to-print .STL files that you can output in any quantity you like. Many of these files are freely available on websites like Thingiverse, and others can be purchased on popular sites like Cults3D. Try searching for things like "figures", "people", "crowd", “man", "woman" – but be prepared to wade through lots of fantasy figures, etc. to find what you like.

Some examples of figure files available from Dolphin Studios on Cults3D.com

The results you get will vary, depending on the type of printer you have and your level of experience. FDM, or filament printers, use large spools of plastic (usually PLA or polyactic acid) and are capable of printing pretty good figures if you learn how to dial in the settings (temperature, layer thickness, support structure) just right. It took me a while to fine-tune my own settings, but once I figured it out, the output was quite good.

Resin, or DLP printers, use a different process that exposes a UV light-sensitive resin layer-by-layer to create a figure on a build plate. Like the various types of plastic available for filament printers, there is a wide range of resins to choose from, depending on your needs. Also, working with resin can be a little tricky, since it requires careful handling and disposal. That said, resin printers can provide a higher level of quality than filament printers—and this is one reason why it is the most popular printer for those who print very complex and detailed fantasy and gaming figures. As always, getting the print settings just right and learning by trial-and-error will lead to good results.

Some of the track spectators I have printed on my filament printer. Time to paint!

My own experience has led me to use both free and purchased print files for most of my figures, which will supplement the dozens and dozens of vintage and more recent figures I had collected over the years. I have both FDM and DLP printers, though I have mostly used the filament printer up to this point, since I have been able to get its figure output to be very consistent in a short period of time.

To see some really excellent track figures, creative ideas and discover some good resources, there are a few Facebook groups you may want to check out:

STNE Scalextric Trackside NE

Over the coming months, I’ll highlight some of my own figure projects and provide some pointers on getting the most out of your printer, as well as some examples of conversions and repairs I’ve made when the printer’s output was a little less than perfect.

Avant Slot Looking to Build on Growing List of New LMH / LMDh Cars

I sometimes laugh and tell people I am "All Endurance Racing - All The Time" - which is kinda true - from the early 60's to the present day, I love my Le Mans and IMSA cars. Even with a relatively tight collectors focus like that, there are still so many cars out there...and the growth of 3D printing has put even more of them in reach.


That said, it is good to see that at least one slot car manufacturer has put a flag in the ground and has plans to produce some more of this growing list of WEC / IMSA Endurance Racing cars. I saw this announcement from Avant just recently, and it is an ambitious release list, to be sure. In real life, endurance racing is seeing a huge influx of new (and old) LMH/LMDh participants, including Porsche, BMW, Peugeot, Ferrari, Cadillac, Acura, Glickenhaus and even Vanwall and Isotta Fraschini!

I'm sure some of these cars will be (or already have been) modeled by some of our 3D printing superstars, but it will be nice to see some new products from our slot car manufacturers, too. SRC will be producing a Porsche 919 soon and Slot.it will add an LMH Oreca car as well. That will no doubt be used by many privateer teams, thus allowing a wide array of liveries. Acura is using that chassis, so maybe that will be a car we can look forward to. Let's hope!

Slot Car Technology to Release "The Bench" V2 This Summer

For those who are focused on performance and want to know everything about the cars they build and race, there are helpful tools out there to help. I just came across this new testing bench that not only looks good but also promises to deliver a lot of info about your slot cars and engines.



The well-sized test bench will fit both 1:32 and 1:24 scale cars.

I'm not sure about the manufacturing process, but some of the parts look like they may be 3D printed--which is really great to see. I am continually amazed at how this technology has opened up so much creativity for the slot car hobby--where small-scale manufacturing allows us to test products and ideas and modify them quickly as they are brought to market. "The Bench" by Slot Car Technology is very attractive and appears to deliver a lot in a compact package. It's supported by a smartphone app that displays all the critical info.

The unit has adjustable power and appears to provide testing of acceleration, RPM, braking, voltage curve and most other critical performance factors. In addition, the manufacturer will be adding additional plug-ins to test tire break-in, magnetism and vehicle maintenance. The app images all appear in French, but I would think there would be an English language choice available via the settings; even if they were not, it seems to be easy enough to figure out. The projected price is about €220. To get all the information on the test bench product and its app, visit their English translated website HERE:

Hearns Workshop Chair Range Will Ensure Your Race Fans Have a Place For Their Fanny

These are some nice-looking chairs.
The explosion of 3D printing has made it possible for hobbyists worldwide to enjoy a wider range of track accessories than ever. With printer prices coming down to manageable levels, you can always print your own - but the hardest part of the job is to design the objects themselves in CAD, and create a quality file that will look good and be true to scale.


Melbourne's Hearns Hobbies has established Hearns Workshop, which will specialize in the creation of finished parts, accessories and other bits and pieces that will be useful to modelers and hobbyists. Last week they featured some new 1:35 scale chairs that they are working on, which would probably work fine for any 1:32 scale slot racing track. If you've got a spot for a cafe or beer garden on your layout, some of these would look great. Now all we need is a table!

Hearns Workshop also has figures in several scales; one that caught our eye is this magnificent "Selfie Girl" who has taken time from watching the race to make good use of her cell phone. Drop her in front of a driver and you've got a wonderful little vignette.

Another Source for 3D Printing Slot Car Body Files...

While I am greatly intrigued by 3D printing, I have yet to dip a toe into the technology yet; not so much because of cost (though good printers have become rather affordable now) but due to the fact that I have so  many other projects to do first --like build a new track--that I don't feel like committing to the expense right now. I have visions of the printer and software just sitting in my workshop and on my PC while I get up to speed learning how to use it, and I figure I can do this later.

Still, I've picked up enough knowledge to understand the possibilities, especially by watching various episodes of the Worldwide Slot Car Chat, where it's common to see awesome 3D creations on display. There are of course a number of sources for model files for cars, figures and track accessories; I just wanted to highlight one I recently came across - available on www.cults3d.com and offered by a seller HORA80.

A Maserati Merak - offered by HORA80

Understand that these are not the printed bodies themselves, but the 3D files you will need to print your own. You'll still need to run them through a slicing program and set them up for whatever 3D printer you (or a friend) own, and actually output your own body. That said, the range of files and cars available here is pretty stunning: Sports Cars, Racing Cars, Off Road SUVs, Classic American and European Cars, Commercial Vehicles--just about anything you might want. The site says that all model files are prepared to be printed at different scales and the file has several versions with different wall thicknesses to facilitate printing.

Something you don't see every day...a 1972 Ring. Bros. AMC Javelin

While I cannot personally vouch for the quality of the model files (it looks like over 1000 may be available) I can only point out that there have been almost 4,000 downloads and sales of over $30k. With almost 1000 followers, it would seem to follow that HORA80 has probably established a pretty solid reputation as a source for good 3D print files.  At $9.80 USD a file, it seems pretty reasonable way to get a car that's may not be available any other way except for printing your own. 

If you do decide to give them a try, be sure to let me know how things worked out!
