1/32 midget build thread " finished!"

[btaylor]

I know i said no more blurry pictures,but i needed to get this up while i wait on the bodies to come in.
This will need to be done before fitting the motor to set up your gear mesh. You will need to take about .040 off the backside of your ring gear. i do this with a sharp x-acto blade,you need not be perfect,as the gear may need to be sanded slightly to assure final gear lash. i save this cut off piece to use as a thrust washer on the load side of the rear axle.This step is out of sequence,but its something to do while your solder job cools.

As soon as i get done with this build,one of your bodies is getting an ARTIN transplant. i have figured a great way to get the guide and brushes up under the nose of those beauty's! I will share with you when i get the main rails bent.your going to love this! i have already done a test fit and its works great. the artin bulk buy would be great for a club to split the overall cost. As much fun as these things are,a person could use all 30 of them for sure!

Thought this would be a good time to do a sub assembly on the brushes and isolator assembly. this picture shows the 1/43 artin chassis brush mount.


you will need to bend the tabs up that hold the brushes in the chassis.

What you will end up with

We will be bending the bottom tab up or you could cut it off as it is not used, the top tab will be bent straight up.


at this point we need to fold the metal part of the brush holder in on itself,and put a dab of solder on the top tab.
Solder your motor wires to this tab

Slide some shrink tube over the wires all the way to the brush itself,covering the tab.

Another sub assembly while waiting on the body to come in.
This the isolator plate that keeps the brushes from contacting the frame,this is really the key to making this whole brush/pin assembly work.I use an old dealer ship temp tag in plastic,but can be made out of anything that does not conduct electricty

The shrink tube keeps the brush and wire from contacting the rails

Use the chassis as your drill guide or for marking the holes we need for the pin and brushes to pass through.

Drill the hole slightly over size so the isolator will slide over the pin and brush tubes

you do not have to be perfect on this as the plate will be trimmed to fit the shape of the body,so leave plenty of material around the area.

If the USPS Tracking is correct,the SRP bodies should be in today! :D
Armed with my new camera,i should be able to proceed with this build with a lot more clarity,at least in the photo area if no where else :) Hopefully i can start at the basic chassis building part as i kind of skipped over it not having a body to help with the wheelbase setup.I am sure some of you have multiple projects going at the same time ,so you will understand why my build style is all over the map! anyway,by tonight i should be back on track,sorry for the delay if you have been following and building.

The holiday delayed my shipment a bit,But the SRP bodies came in.Should be able to go forward with the build now.
Here are some pics of the wheelbase and track width of the midgets.

Great tutorial. I really like the fact that even if the first page shows nice cars, we have the feeling that we CAN make this kind of cars too. I mean sometimes, we see tutorials with great results...Then we see the method...And we think to ourselves it's too complex.

Your tutorial give some hope to beginners like me ! :D

Really great tutorial! I know lots of folks have been trying to figure out how to do the chassis for these smaller body types.

[btaylor]

David,these chassis are real easy to build,and they handle way better than any pin guide cars i have had over the years.
it may be due to the short wheelbase,weight factor? dont really know,as the first one surprised me how well it drove.
I have been playing around some with the frames trying to tweek out the best overall design,and i will incorporate those options when i start back on the tutorial. And thanks for the Kudos! it is my first tutorial.

I need to get back on this tutorial,ive been doing all sorts of other stuff and not getting this finished.

[HomeRacingWorld]

Sometimes we get too many irons in that fire don't we?

[btaylor]

Got my new chassis board in,should make these midget builds a little faster!This pic shows that you can use square tube for the main rails as well. As long as your width does not exceed the inside dimension of the body,You can use about anything.
