Midget Racer

Rodney and I talked about building a pair of Midgets on the way home from Eddie’s Slot Car World the other day. We came up with some simple rules for our new 2-car “class”:
1. Pittman 196B motor, “and keep it stock Rick!”
2. Monogram brass chassis plate.
3. “Don’t put a big ugly guide like a Jet flag on it Rick!”
4. We will both run the same gear ratio and rear tires once we decide what works best.
I’m using the EJ’s Hobbies reproduction Midget kit for the body, driver and decals (if anyone wants a good deal on the rest of the kit, PM me):
The motor is a new old stock Pittman 196B. These are great motors and come up on EBay quite frequently. I’ve been running mine on the power supply at 6 volts for several hours a night to break it in. It draws .7 amps and barely gets warm. It’s the closest thing to a “perpetual motion machine” man has yet devised:
I’m using original Monogram wheels and trying Tiny Motors (among others) silicone reproduction Monogram Midget tires:
I’ve also got some original Monogram jam nuts, spacers and a chassis pan I found on EBay. The spur gear is a pot metal MDC and the axles are unknown new old stock:
Time to start a building!

This looks like a fun project. Man, I don't have to tell you but those styrene builds sometimes take a lot longer to get into shape than the classic vacuum-formed Pro replicas.
PS: You haven't heard from me lately because I've been held hostage for the last couple of years by a bunch of styrene kit conversions including my latest muse... Renwall 1966 Virgil Exner Revival kits... Ouch!

I'm looking forward to this! It should be a whole lot of fun to watch and I'm sure the typical DC-65X awesome workmanship will shine through.
Once done, I'll bet the midgets will be a blast to race against one another!

What kind of zapper are you using to refresh the magnet? I remember an earlier article about good results zapping the magnet but I didn't see what what you're using.

The EJ's kits might be hard to find. I believe they're sold out...

Don,What kind of zapper are you using to refresh the magnet? I remember an earlier article about good results zapping the magnet but I didn't see what what you're using.
I believe Rick bought a new Trik Trax zapper a year or two ago.
I intend to live forever! So far, so good.

ABS... ... will the same model glue work, Marc?Yes indeed, these are a blast from the past and very nicely done. Caution!! They're not styrene, they're all done in ABS plastic... the EJ's kits might be hard to find. I believe they're sold out.
I bought my kit from Ed at EJ's just a few weeks ago. He's still promoting them on his web site. Here's a link:
EJ's Hobbies
Here's my "Big Dog" Zapper, Don. It's old school and I love it.What kind of zapper are you using to refresh the magnet? I remember an earlier article about good results zapping the magnet but I didn't see what what you're using.
The magazine article said to just jam a piece of brass into the front of the motor and solder it to the frame . It worked for them but I decided to do something a bit neater.
To mount the front of the motor to the chassis pan I notched the Pittman magnet retainer and soldered a piece of 1/4" wide K&S brass sheet to it.
The Pittman side plates got the holes countersunk for flat head screws to clear the Midget body.
The magazine's solution to mounting the rear of the motor to the pan was to bend the chassis "ears" to fit the wider Pittman motor. With the motor pushed a far rearward as it would go the wheelbase would be short of 3" (the wheelbase of the EJ's Midget chassis). I decided to cut notches in the Pittman axle carrier to fit the Monogram chassis. I also trimmed some extra metal to slide the motor more to the rear and drilled and tapped for 2-56 machine screws:
The chassis ears got trimmed too (at an angle ):
Next I need to align all this junk while I screw it all together.

On the glue part, no, you'll need to buy some ABS glue. Super Glue company makes it in a tube, it has a different make up. The standard styrene glue won't hold. And make sure you scrape through the chrome to get a good bond. Ya don't want any of them shiny parts flying off...
It's a super kit. Very nice quality. The decal sheet is also outstanding...
How do you like the instruction sheet???

Hi Rick,
This looks like a fun project. Man, I don't have to tell you but those styrene builds sometimes take a lot longer to get into shape than the classic vacuum-formed Pro replicas.

Which Renwal kits are you building? I just built the Stutz and the windshield/ frame assemble was tricky.

The rear motor attachment nested into the chassis "ears":
The front motor mount.........
........is screwed into a nut soldered to the bottom of the chassis pan:
The magazine article has the chassis pan flat up against the bottom of the motor. Then they had to cut a hole in the pan for the armature to spin freely .
I set mine up like this:
The chassis pan is parallel with the track surface and the motor is angled down until the front just touches the pan. No hole is cut in the pan for more weight down low.
Different strokes for different folks

It's not so much the construction, since that is a given... but it's the beautiful photography too! *sigh*

Hi Gary. I'm cleaning up a Stutz slot car and have an unassembled Duesenberg which will get a scratchbuilt frame. OK...back to our regularly scheduled programming.Which Renwal kits are you building? I just built the Stutz and the windshield/ frame assemble was tricky.

I love the look and "feel" of the chassis. Carry on!
Thanks Bob, onward I go
………So... who is going to paint it? NOT ME!
You’re not . OK, I’ll paint it . Say, are you set up again to paint clear bodies? Hint, hint !
…….These chassis bend up and down pretty easy and cutting a hole for the arm may be dangerous.
Tell me about it! Is there such a thing as “full soft brass” ? I swear I can bend it by starring hard at it .
Hey, thanks Barney

The set screw gets adjusted until the body mounting screw tightens against it and the body can still move around and "rattle" a little.
I soldered a washer on the frames body mounting slot to keep the body from sliding front to back:
The rear of the body is held up by a .040" thick piece of plastic glued under the seat. It contacts the top of the motor:
The body sits level with the track and nice and low:
I've got glued and trued Monogram repop tires from Pauls Slot Car Shop (urethane), Tiny Motors (silicone) and good old 40 year old 30mm "Germans" ready to try out.
Time for a track day

I just ordered another midget from Ed, I put together one about 3 or 4 years ago but sold it at a swap meet. Gonna take my time and have fun with the new one when it gets in, not nearly as much scratchbuilding as yours but it will be a hoot!
