Topic: On The Bench - CHEAP Slot Cars?

As a track owner and occasional NASTE race host, I am always looking for CHEAP, or should I say inexpensive slot cars. I have two primary objectives when I introduce a new class for racing here at TooBad Motorplex, or to introduce the NASTE IROC racers to a new type of slot car; 1. low cost to purchase or build, 2. simple rules for modifications. There was a time I could scratch build cars pretty cheap. I built and sold the original NASTE Chassis cars using Radioshack motors that were a mere $3.49 each, and rubber rear tires that were $1.50 a pair. I sold the complete brass chassis cars for $15.00 less bodies. Racers were able to purchase new model kits for bosies for $5.00 to $8.00 on sale at that time. The total cost of a car was approximately $23.00, less paint of course.

  That was almost 20 years ago, and I am now of the opinion there are NO cheap slot cars to be built anymore! Now days just the cost of the running gear, axles, gears, guide flag, and wheels will cost you at least $15.00. That doesn't even include the cost of the brass, which is substantially more expensive now days! What I have learned over the past few years is; the best way to build a cheap car, is to start with a complete cheap car!

  There are many potential cheap project cars to start with. Mainly what I look for in a potential project car is; good parts for a chassis, or a nice useable body. Good candidates that can be picked up cheap are the Parma and Champion RTR cars, such as 1/32 Womps and 1/24 Flexi's. If you can buy used cars in a large lot it will reduce the cost per car even more. If that requires more initial cash outlay than you want look for a partner or partners to divide the lot with. I shoot for an initial car cost of $20 or less.

Re: On The Bench - CHEAP Slot Cars?

Here's an attempt to build a cheap slot car for racing here at TooBad Motorplex. For this car I will be starting with a Parma 1/32 car I picked up somehwere along the line in my many years of collecting slot car stuff. To get started, here's my work bench in its current stage of unorganized mess. It's a wonder I can get anything built in this mess!

This particular Womp started out as a cherry Corvette, complete with a nicely done interior. Somebody did a nice job on this car!

http://www.naste.org/members/bill/IMG_9247.jpg

Probably a better candidate for a project like this would be something more along these lines. This Womp would probably have a much lower purchase price because it is pretty well BEAT!

Re: On The Bench - CHEAP Slot Cars?

For this project what I am mainly interested in is the chassis and running gear, axles, guide flag, wheels, crown gear, and hardware. I will be replacing the motor with one more suited for use at TooBad Motorplex with a little less power and torque than a 16D. I am replacing the 16D with Professor Motor's version of the Fox 10. These motors sell for $7.50, to which you must add shipping costs. I usually try to order enough parts for free shipping, or at least be able to spread the shipping costs out over a number of items.

Re: On The Bench - CHEAP Slot Cars?

Paul Gage is making urethane tires to fit the Parma Womp cars. For $8.99 you get a total of four rear tires. Again you must add shipping charges to your cost, but it is still a great deal. And these tires last almost forever!

For this car I am also installing a seven tooth pinion gear. Pinion gears cost .90 cents for a pair at Professor Motor.

Re: On The Bench - CHEAP Slot Cars?

In the installation of the motor I decided to use a quick change method of braid installation on the guide flag. This method is popular in our area, and I presume popular most everywhere slot cars are raced. As a slot car racer and builder I NEVER throw ANYTHING away! Here's a use for those old worn out pickup braids everyone has!

http://www.naste.org/members/bill/IMG_9254.jpg

Cut the braid off of the brass shoes that secure the braid to the guide blade. Bend the brass pieces like this:

http://www.naste.org/members/bill/IMG_9255.jpg

Solder the motor lead wires to the brass of the old braid.

http://www.naste.org/members/bill/IMG_9258.jpg

Install the motor lead wires into the guide flag on top of the new braids.

Re: On The Bench - CHEAP Slot Cars?

I am re-using the Womp rear wheels with Paul Gage urethane tires. I removed the old hard rubber from the rear wheels.

http://www.naste.org/members/bill/IMG_9256.jpg

I cleaned the inside of the tires and the outside of the wheels with Isopropyl Alchohol. Rubbing Alcohol has other ingredients and can leave residue when used for cleaning parts.

Re: On The Bench - CHEAP Slot Cars?

I used clear nail polish (thanks Honey) as an adhesive to mount the urethane tires to the wheels. I applied the polish to the inside of the tires and the outside of the wheels.

http://www.naste.org/members/bill/IMG_9261.jpg

With the wheel positioned flat and vertical on the table I pushed the tires onto the wheels.

Re: On The Bench - CHEAP Slot Cars?

Here's the assembled chassis.

http://www.naste.org/members/bill/IMG_9264.jpg

My plan is to put three of these cars together for the next NASTE IROC race here at TooBad. I will be using clear Volkswagon bodies on the cars. Professor Motor sells the Parma Home Set clear Volkswagon bodies for $5.49.

http://www.naste.org/members/bill/IMG_9265.jpg

So here's the cost to build this car: motor = $7.50, 7 tooth pinion gear = .45, rear tires = $8.99, clear body = $5.49, for a total of $22.43, less the intial cost of a complet Womp. If I had an initial car cost of $20 this project cost me $43.43 without figuring in the cost of shipping on the parts. Not really what I would call a CHEAP car! Looks like this one is a FAIL in the cheap category. Oh well, I hope it runs well!

....................On to the next car..................

Re: On The Bench - CHEAP Slot Cars?

My good friend Dave Smith got a bunch of us hooked on racing these Volkswagons on slightly modified Womp chassis years ago.  I still love these cars and these will be TooBad Motorplex's version of the class Dave Smith started. Thank you Dave!!!

Re: On The Bench - CHEAP Slot Cars?

Did a little track testing this morning. Fun car to run!

Re: On The Bench - CHEAP Slot Cars?

Ran the test car around the track a bit last night and thought it ran great.  Nice build there Bill.

"Big Smooth"

Re: On The Bench - CHEAP Slot Cars?

I agree, very fun and easy to run.

Race cars are neither beautiful nor ugly. They become beautiful when they win.

Re: On The Bench - CHEAP Slot Cars?

Bill: I found the fox 10 motors on line today, ordered a couple. I guess i better get some tires now, and get busy finding my womp stash to build up a car. You obviously have too much time on you're hands to keep coming up with these new classes!

Re: On The Bench - CHEAP Slot Cars?

Sorry about that Goose. I've been thinking about these for quite awhile. Right now I'm just looking at getting 3 or 4 up and running for the next NASTE IROC race here at TooBad Motorplex.

By the way, the part number for the Paul Gage urethane tires is PGT-22160.

Re: On The Bench - CHEAP Slot Cars?

Been working on restoring some old junk for the over 50 class, This progress is painfully slow because everything has to be found and ordered online, I sure miss the real hobby shops of the old days but selling a few sets of tires and braids and maybe a body or two just wont pay the support a store now a days. Any way this first pic is of the Monogram Ford I had as a kid- chassis sorted, body stripped ( amazingly without melting it) repainted, driver detailed, Paul gage tires, windshield replaced and now just waiting on decals-can't find originals so will use repro cox gt 40, not as dark blue as they should be but oh well, gotta get this thing done so can crash it !

Re: On The Bench - CHEAP Slot Cars?

This is a Lola body for a classic chassis- the moon buggy looking manta rays just don't cut it for me ( with all due respect to Ed big daddy Roth the bubble top master) this is not the body I would like its one of those retros I think- too thin .010 and too wide and square looking but with enough decals its not too bad- I didn't want to screw up the pristine classic chassis so I came up with a body mount of 1/16 brass tubes slipped thru existing body mount screw holes held in place with some wheel collars and the old bent pins- kinda scrunched the sides in a little and it doesn't look too bad - and hey its for Brian Dickerson to race so its not like I have to be seen with it right?.

Re: On The Bench - CHEAP Slot Cars?

This is a cox Chaparrel I got amazingly cheap- less than 45 bucks I think on ebay- it was in real bad shape crappy paint, glue all over everything but the chassis looked cleaner than my original, well after painfully stripping and sanding and clearcoating the windshield to hide the sanding scratches and repainting this is what I end up with- now waiting for tires and decals- I couldn't go with the brown repro decals ( only a Texas oil inheritance millionaire would paint a race car brown) (nuthin personal Jim Hall, just sayin) and I needed a dark color to hide some bad bodywork on top so went with a metallic blue theme, might try to make my own light lenses from acrylic or may just leave em out as I heard the real ones fell out all the time also.

Re: On The Bench - CHEAP Slot Cars?

This showed up today-again amazingly cheap on e bay...might be due to the body...aye carumba! its called a Hussein...I guess as in Saddam..dead wrinkled and filthy, but the chassis is what I was after and it actually looks amazingly straight and low time- no scratches on the motor can from bottoming like mine in the roadster and the motor brushes are full height and original so real low time- These are easy to adapt hard bodies to so that's my plan and of course more tires from our friend in Canada

Re: On The Bench - CHEAP Slot Cars?

P.S. If anyone needs something to race in the over 50 I am getting quite a collection of classic stuff and you are all welcome to borrow and race - my goal is to replace the Manta ray and garvic bodies with more realistic stuff from the era- primarily can am and etc. but in the mean time they are runners and anyone racing a manta ray while wearing a top hat ala Ed Big Daddy Roth should get 3 bonus laps added to their total just for style!

John, Very nice work, thanks for posting! It is great reading and viewing!!! Looking forward to seeing & hearing more!!!

P.S. what did you end up using for a windshield in your GT40 roadster?

Re: On The Bench - CHEAP Slot Cars?

I now have 2 VW Womps together, VWomps we'll call 'em. Ran some laps to test different gear ratios. With a 7 tooth pinion and 31 tooth crown I ran a best lap of 9.711 seconds. With a 7 tooth and  28 crown I ran a best lap of 9.076.  No surprises here, just simple math. Each car was easy to run with either gear set. Looking forward to testing on Monte's track on Sunday!
