Samson Classics frames and Classi-parts

Over the past few years, I have been building slot car frames for old friends and new friends alike, and supplying some to various slot car raceways around the US to support the growth of 1/24 scale Retro slot racing.Frames are time-consuming to build, as each one is totally hand-made (apart from the steel guide plate I use). I make the motor brackets for inline cars, I cut brass strip and tube to size, trim lengths of piano wire, and then solder it all together, so each frame takes between 10 and 15 hours to complete.

In my Photobucket Slot Cars album (see link to the right), there is a section for Customer cars that shows a lot of what has been done over the past few years.

To augment these frames and provide even more superior performance, I have designed and am now marketing some extra products.

Weighted Guide flags: These are the latest from Samson Classics. I have been experimenting with weighting the blade of different makes of guides with different heavy compounds, starting out with a tungsten paste, and even trying some pieces of lead. The most effective it seems are some small tungsten pellets that I have obtained. This allows me to weight guides with a range of added weight. I will be offering guides with 4 pellets (adding approx. 0.5 grams to the guide weight), with 8 pellets, (about 0.9 grams extra) and with 10 pellets (approx. 1.3 grams extra).

Ball Bearing Front wheels: Retro slot cars support a lot of weight on their front wheels, unlike some other forms of slot cars. Ball bearing-equipped front wheels help to  minimize rolling resistance, and therefore get higher speeds, especially in banked turns where the frame is carrying extra load. There are a number of such designs on the market and they work well, but I felt there were some basic problems to iron out. I designed my wheels to use a bigger bearing than the competition and to fit onto a sleeve rather than run directly on the axle. This way, I could provide a wheel that locks in position with a setscrew, and requires no soldering of retainers and therefore no flux or solder to contaminate the bearings. I also developed an improved method of cutting the hard foam tire so that these wheels run more concentric than most others.

These wheels are available now in many Raceways, as well as directly from me, in two widths and four diameters to suit all the various Retro classes being run around the world.

“Harry’s Nuts” These are a multi-class product, useful for any slot car guide flags that have a 3/16″ diameter post. Over the years, slot racers progressed from locking the guide in place with a collar, to using a washer and a screw, then to melting the screw into the guide, and finally started using #10-32 nuts to hold the guides into the cars. Each iteration provided more precise control of free play and easier adjutsments, but each had its drawbacks.

Back in the early 1980s, a talented engine machinist from what was then Southern Rhodesia (now Zimbabwe) emigrated to South africa and joined our slot car club. His name was Harry Odendaal, and he was the first to produce this design of guide nut. He made them in his spare time and we used them with great enthusiasm, in fact I still have one or two of his originals. They were much more accurately made than a regular nut, and the top-side drive meant they were much easier to assemble.

I decided to have these made in quantity and release them to what turned out to be a hungry market, and they have been an instant hit all over the world, including back in South Africa, where they had been struggling to maintain the quality and price level I can now provide.

As with the wheels, these are available from various raceways in the US and from me direct. Soon they will be available in the UK via a local distributor as well.

“Clip-Rite” Controller saver

Ever had your car run away or a controller fuse blow because you got the hook-up wrong?  “Red-to-red, black-to-black, white-to-white” sounds so simple, but in the heat of the moment, and especially on a strange track, this sort of thing happens. Here’s a solution:

Called “Clip-Rite”, it helps you hook up right each time. Just set your wires in the rubber buttons to match the track sequence once , then after that it’s plain sailing!

The rubber cable clips accomodate wires up to 5/16″ diameter, which is as big as any I have seen on a slot car controller. The wires do not come out esily, but it is quick and simple to change the order for a different track.The base plate is clear lexan, and the whole thing is 5″ long by .800″ wide, so it does not take up a lot of space in your box.

Soon to be available at selected raceways around the USA, and already available from me direct.

“Mix & Match” Numbers

Others may be like me, in that I like to use the same number on all my cars, so I tend to end up with lots of sticker sheets all with one number missing. So, I have made sticker sheets from high quality adhesive vinyl with 12 numbers and meatballs, all the same number.

But there’s a difference. The numbers are cut from the sheet, and also from the meatballs surrounding them, so it is possible to use just the number or just the meatball:

Of course, by buying a few different colors, the mix and match combinations are endless too, blue numbers in white meatballs, black nubers in yellow, etc.

I have the following colors available: Black, Blue, Gold, Green, Red, Silver, White and Yellow.

Number sheets of any number from 1 through 0 (12 numbers per sheet) and sheets with three each of 1 through 0 are available, in two fonts for now, a block font as in the shots above, and an italic font like this:

On special order, I can do reversed numbers for use as masking, or multi-digit numbers.

Again, these will be available through selected Raceways soon, or direct from me.

“Flex-Rite” Tweak Board

This is a slot car-size version of the famous tweak boards used by RC racers back when RC cars had no suspension. It allows you to quickly identify any twist in a slot car frame. or uneven weight distribution from left to right.

The Flex-Rite is adjustable for wheelbase all the way up to the 4.5″ needed for Retro stock Cars, and down to the shortest 1/32 car. there are engraved alignment marks set at 2.5″, 3″, 3.125″ and 3.25″ to center all widths of retro cars and others.

The Flex-Rite is packaged unassembled, with a set of assembly instructions. It is simple to use and will provide quick and easy checks for performance issues such as pulling under braking, different cornering to left and right, tire size inequalities, etc.

Available now from me directly and from Raceways once the word gets out.

Brass Guide tubes for 1/32 scale scratch building

These popular products are available already from me directly or from Slot Car Corner and Slot Car Corner Canada. There are two styles for different mounting techniques, a flat mount and a spigot mount. Either style fits into a 3/16″ hole in a chassis or guide plate.


The flat mount tubes are intended to be mounted from the underside of a guide tongue:

The spigot mount is designed to be mounted on the top surface of the guide tongue:

NOTE: The photos show a steel chassis, but these tubes will fit any 3/16″ diameter hole on regular brass chassis as well.

Tubes can be ordered with four different inner diameters:

  • 1/8″: For use with vintage guides and TSRF guides
  • 3.5mm: for use with NSR and guides, as well as the ScaleAuto SC16007 and 1608 replacement guides and any others with a similar size
  • 3.7 mm – to fit the Scale Auto SC1603 and 1604 guides, the Sloting Plus guide, and any others with a similar size
  • Special taper: These are new, specially tapered and shortened to provide a good fit on the CH07 wood track guide. NOTE: These are special order from me only at this time, not available through the retail outlets yet.

The tube length is generous enough to accommodate all guide post lengths, and can obviously be cut to size as required. The new version is already shortened somewhat but will require a longer screw than is provided with the guide unless trimmed further.

    What is your current build time? Looking for a Can Am for a King and possibly a Retro Pro if you are doing them.

    Hey Dennis – trust you are well ?

    You up to building 2 chassis for Presto Park for me (march) – Vintage/Retro meeting 🙂

    Greets – Anthony

    Dennis Hi.
    I can not open any of the pics, what a pity as I really miss the old scratch built days, I’ve got a brand new Mura Group 20 and I intend building a brass/piano wire chassis circa 1978. Regards Colin
