(Photo below for reference)  It has served me well over the years, but I would like to move away from the sanding drums to an abrasive metal drum. Does anyone know if the SC-5073B abrasive drum intended for the "newer" SC-5072 EVO 2 truer fits the older one.  For reference, the shaft in the 5040 is 5mm and the drum diameter with abrasive mounted is ~34mm.

Thanks!

Back in 2020 I wrote a ten-part series on the Jadlam blog about tuning a Scalextric car. My aim was to work through the steps for improving a standard Scalextric model by only using the parts that came in the box. I picked the new at the time Mustang GT4, because I thought there might be quite a lot of potential for improvement... And I wasn't wrong!

Jadlams have recently built a brand new website and the blog has gone. So I've dug out the images and text to post on the forum. I've had some good feedback over the years about the blog posts and I want to share the series with a new crop of Scalextric racers at my club, Worthing HO Racing.

There is a post introducing and linking to the blog posts on the SlotRacer forum here. I'll edit that once the posts are up on this thread.

These are the ten posts in the series...

I don't have the full text for a couple of the posts, so those will get re-written.]]>

Hi Slot Racer Online Forum Members:

Merry Christmas!

I am a new member and a novice seeking TIRE Tips advice.

I have late 1990s and early 2000s vintage Ninco 1/32 analog Porsche 911 SC & 934 slot cars with “50” prefix part numbers featuring flared rear wheel arches, ribbed tires, and prominent "whale tail" or "tea tray" spoilers made in Spain running on an analog Ninco track, specifically:

Ninco 50331 Porsche 934 #9 black window 

Ninco 50334 Porsche 934 #58 black window

Ninco 50371 Porsche 911 SC #4 black window

Ninco 50386 Porsche 911 SC #1 black window

Ninco 50573 Porsche 911 SC #16 black window

Ninco 50652 Porsche 911 SC #18 clear window with driver Gulf livery San Remo Rally

Please attached pictures.

My internet research (please see “Data Sources” below) suggests that the stock tire sizes for the late 1990s and early 2000s vintage Ninco 1/32 analog Porsche 911 SC & 934 slot cars are:

Front Tires: 19mm (diameter) x 10mm (width)
Rear Tires: 20mm (diameter) x 11mm (width)

Data Sources:

https://www.google.com/search?q=tire+siz...s-wiz-serp

However, that is subject to verification!

My track is a Ninco analog 1/32 track used by BEGINNER slot car racers.
Mostly my grandchildren (age 10 and under).

Question:

Can any Slot Racer Online Forum Members:

1.    Validate the correct FRONT & REAR tire sizes for my specific Ninco Porsches?
2.    For cars running on a NINCO analog track by BEGINNERS:
3.    Reply with Tips for Front & Rear tires upgrade recommendations (including Brand, Part# & Hyperlinks)?

If “Yes", please enter data below and send it to me:

Thank you in advance for any Tips you can offer!

I welcome any insights and/or advice that you may have to offer.

Finally, I am seeking to purchase a User License for "Ultimate Racer 3” track design software.

Thanks again!

Thanks to Nolakers tyre cleaning on a figure of 8 track for 10 hours, I put the wheels back on the truer to clean up for about an hour, then fit them to the car destined for a UK proxy (Targa Florio).

At the club track an hour early, tried the car I'd used for testing last week (NSR Porsche 917) with a set of known good Ultragrips and was unimpressed by the cars handling...time for a rethink.

Get another proxy car out, a Fly WSC 95 Joest Porsche with my 3D chassis/pod and tried the 'zero graining' tyres...that's more like it. Did a few laps then decided to try another proxy car which is a lovely runner, a Fly Porsche 908/3 with my 3D chassis and SlotIt SW pod...an immediate improvement, these tyres aren't as bad as I thought, lets keep going and I must have done about 100 laps with them and they were starting to polish with little tyre dust so decided on a proper test.

First photo is after about 100 laps on our polyurethane painted wood track.

.jpg 100 laps.JPG Size: 1.49 MB  Downloads: 110


Those are looking much better than they did after running the NSR Porsche 917.

I then did another 100 laps in 33 lap segments, cleaning with tape. This next photo is after 200 laps, fastest lap was 6.038 which is quick for a proxy car on our track.

Then I ran another 100 laps in 33 lap segments, fastest laps was 5.906 which is as good as this car has gone on treated original Ultragrips. The rubber cleaned off the tyres on the tape is 300 laps worth.

Then I ran 100 laps non stop...fastest lap didn't improve but regular 5.9's is excellent. Rubber cleaned off the tyres is shown on the tape.

Finally, I swapped the tyres round and ran another 100 laps. Initially lap times were down but gradually started dropping again and will be in the 5.9's

.jpg post test 100 laps non stop.JPG Size: 1.11 MB  Downloads: 108


So I take it all back...thanks to Nolakers, I decided to revisit these and confident they will easily last a round of a proxy series without performance dropping off.

One other thing, the NSR Porsche 917 I had intended entering in the proxy is being replaced by this Fly 908/3 with Predator 22k.

...I've since rounded the outside corners which has made cornering a little smoother.

N.B. these tyres have not had any tyre treatment, only track time to polish them smooth.]]>

After some help please. 

Our original club track we built is a four lane, routed track,  12mm mdf.  You can find it in the Show us your track section,  under Routed Raceway. 
Until last year it was permanently mounted onto a very large board,  with an electric winch system to lower it into place for racing.   It is now no longer permanently mounted, and now goes together much like a jigsaw, in 9 pieces of differing size.   
To power it up would involve soldering 154  sections of copper tape, just for one evenings racing.  They would then need removing to store it again until next time  Tappingfoot

So, has anyone used, or come across, or have knowledge of, 6mm highly conductive copper tape that could be used without the need to make 154 soldered joints.   Just need something that will stick straight on, bridge the gap, and give us power without the need for soldering. 
 Other option is to solder one complete lane where required,  and butt each section together,  and see how it goes.....

Any help or thoughts appreciated  Thumbup

I am known as the organiser of the Slotracer proxies but have been really surprised with the current proxy with the number of cars arriving whose tyres needing re-gluing, even before they get onto the track.

Personally speaking, although I tried more exotic types (Rubber toughened)  Specialised slot car tyre adhesives in the past, I never felt that they have lasted that long. I have therefore tended to revert to the “off the shelf” Superglue which I use on my Club cars over many months without having to re glue them.

So I wondered what other people’s experience is, I can see that the common Superglue is rather hard, and that others tend to be “softer” and should in theory give a better ride properties to the tyres on the wheels, but is there a REALLY GOOD tyre adhesive which is soft and flexible and gives longer term adhesion ?]]> A question about tyre adhesives ?

Three questions: -

Is that what it does?

Any idea if they are still manufactured, as this is the only image of one I can find?

Does anyone have one to sell second hand?

This is intended to be a reasonably comprehensive list of "commercially" made tire truing machines. That means a machine was made in some quantity to be sold to other people than it's creator. This does not include every DIY machine ever made, though some are included at the end if they have appropriate models/instructions to follow. It also does not include any machine that does not hold the wheels/tires at a set and adjustable distance from the sanding medium. Sandpaper-on-a-track type devices do not qualify as truing machines, no matter how steady your hands are. I'm sure I'll have missed some, and some machines will be forthcoming, so please post any I missed and any upcoming machines yet to be listed. It's also worth noting that there are lots of RC machines out there, but without confirmation that they work with common slot car axle and wheel/tire sizes, I chose not to list them, even the Mini-Z ones. If you know of a machine sold to RC racers that definitely works for some kind(s) of slot car wheels, please mention it.

The list is divided into machines designed for metal wheels, usually only truing one wheel/tire at a time, and machines that are designed to hold the whole axle of the car with both wheels still attached and being trued at the same time. Each list is then divided by whether the machine is still available on the retail market in some capacity (even if out of stock, assuming more are being made), and those which are no longer being manufactured by anyone. The order in which any machine appears in the list is NOT an indication of quality or rating. No subjective assessment of any machine has been made. They are in no particular order aside from those mentioned above. Links and images are what I could find while writing this list and may be out of date or no longer accessible in the future. Updated or better links are welcome. Prices listed are retail prices in USD at the time of writing and does not include accessories, taxes, or shipping.

https://www.freeslotter.de/index.php?thr...tester-ges]]> Slot Car Tire Truing Machines Past/Present/Future


This is intended to be a reasonably comprehensive list of "commercially" made tire truing machines. That means a machine was made in some quantity to be sold to other people than it's creator. This does not include every DIY machine ever made, though some are included at the end if they have appropriate models/instructions to follow. It also does not include any machine that does not hold the wheels/tires at a set and adjustable distance from the sanding medium. Sandpaper-on-a-track type devices do not qualify as truing machines, no matter how steady your hands are. I'm sure I'll have missed some, and some machines will be forthcoming, so please post any I missed and any upcoming machines yet to be listed. It's also worth noting that there are lots of RC machines out there, but without confirmation that they work with common slot car axle and wheel/tire sizes, I chose not to list them, even the Mini-Z ones. If you know of a machine sold to RC racers that definitely works for some kind(s) of slot car wheels, please mention it.

The list is divided into machines designed for metal wheels, usually only truing one wheel/tire at a time, and machines that are designed to hold the whole axle of the car with both wheels still attached and being trued at the same time. Each list is then divided by whether the machine is still available on the retail market in some capacity (even if out of stock, assuming more are being made), and those which are no longer being manufactured by anyone. The order in which any machine appears in the list is NOT an indication of quality or rating. No subjective assessment of any machine has been made. They are in no particular order aside from those mentioned above. Links and images are what I could find while writing this list and may be out of date or no longer accessible in the future. Updated or better links are welcome. Prices listed are retail prices in USD at the time of writing and does not include accessories, taxes, or shipping.

Most treatments work well with rubber tyres on the track from 3in1 oil to RC tyre treatments, Koala Klaws, NSR oil, bicycle chain cleaning oil, Olbas oil, Tea Tree oil...I've tried allsorts, there isn't one 'best' as it's more important to get the right tyres in the first place which are NSR Ultragrips (NOT the Evo's) which are sadly long out of production and getting hard to find.

Some tyres don't need treatment on this new track surface but if raced carefully they polish to a shine, stock Revoslot tyres, Thunderslot 002 (again can't find these in the UK) and given time even NSR Evo Supergrips.

Well I found a bottle of something I bought probably 30 years ago and most of it is still there...Redex for petrol.  This is the old style round bottle and has a strong smell, in fact the same smell as my old Toolroom overcoat.

I thought 'why not' and smeared some thinly round a pair of NSR Ultras on one of my cars.  There wasn't really any noticeable improvement for over an hour and much better the morning after, now this is a good sign for me as 'instant grip' treatments have always been short lived so will be trying this on Thursday night.
My only concern is will the Redex attack the rubber too aggressively so that it crumbles...time will tell.]]>

But...

I don't think there are enough nuts and bolts in the pack to fit the side rails. Normal?

Why are there 2 thin nuts and 2 thick nuts in the pack?  The thick ones seem too thick to fully engage with the nuts.

And what are those two members for that stick out from each side of the chassis adjacent to the motor pod? I need to cut them off as they interfere with the fit of the body.]]>

It's hard to describe maybe and I haven't had time to make a video. The cars seem to drift fine up to a point, but if they drift too far away from the rails, perhaps 15 degrees or so, then violently bounce back in the other direction back towards the rails and then de-slot. It seems as though the guide blade gets stuck or reaches a hard limit of how far it will rotate then bounces back quickly the other way. Not all my cars do this, but the ones that do it really takes away from the fun. To me drifting is like the best part of racing, approaching being out of control / too fast, but then recovering.

One car I have that does this is the "Scalextric Porsche 911 3.0 RSR Jagermeister 1:32 Slot Race Car C4211 Orange"
