Chevy Test Drive

i mounted a servo on the chassis and tested crawling

looks good so far

 

 

how to mount a servo on the chassis

 

i had the y-harness's shorter than before

 

i'm planning to cut off the fenders like this

 

 

 

finished the chassis & made tires narrow

i finished the chassis

u-bolts & more leaf springs give less wheel travel tho, i like the chassis

however those tires are not that soft. the compound is rubbery though not soft enough. so i made the tires of tamiya 4x4 mini truck narrow. these are pretty soft

the picture below shows 5 kinds of tires, it is just my opinion tho.

 

let me show how to make tires narrow

new tires and the chassis

these are soft enough, when i press the chassis, the tires look pressed. good =)

 

making u-bolt

i bought a 1.4 metric die(M1.4 0.3mm pitch) to make u-bolts.

i like it. it's easy to make u-bolts

i used 1.5mm brass round stick

 

the test of 100:1 geared motor & drive shaft

i like 100:1 geared motors. they're like snails tho, have more torque
finished a flexible drive shaft. it's better than solid one. no more clicking while it's working

 

the motor test...

they're too fast...

i ordered geared motors(gear ratio 100:1) anyway...

 

working on the chassis & added some details on the roof

working on the chassis

 

i bent the frame rails with bending pliers, some sand, and a torch
at this time, i'm using smaller bolts & nuts. i bought them at an optician´s. they are small but strong enough.
i will use two geared motors for this rig.

now im using only four leaf springs but i'll add more. because the body and the stuff are heavier than i thought

 

and i added some details on the roof

 

2 servos are connected by y-harness's

servos have to be modified a bit to connect to mini-z's pcb directly

 

steering wheel test of 1/24 scale chevy truck projet

i started a project of 1/24 scale chevy truck crew cab,

bought the chevy bodies  two years ago though, have worked on the steering wheel recently. lazy!

 

kyosho mini-z pcb and transmitter,

 

modified the guy to put him into the cab. poor thing!

 

 

 

 

 

 

 

 

 

 

 

 

 

 

SSMT 1/32 scale Ford F-350

[Apr-15th, 2009]

mini-z pcb, micro servo, and 54:1 ratio geared motor...
soldering is hard for me yet >.< anyways...
the stock fets(3004) on the pcb didn't work, so i changed them with different ones(sp8m4). the mortor and the servo work well so far.
the wires look kinda long...

my new project : SSMT 1/32 scale Ford F-350

brass chassis and shackles


<how to bend brass tube>
we need brass tubes, tube bender pliers, pliers, a torch, pieces of wood(chop sticks would be good), and sand

block one end of a brass tube with a small wood piece
fill the brass tube with sand fully
block the other end with a small wood piece as well

heat the tube with torch until it turns in red
(it's very hot, wear gloves before doing this)

bend that with bender pliers slowly
repeat heating & bending and you would get nicely bent brass tubes





making eyes of leaf springs with pliers



i modified my ssmt axles shorter. because the wheel base of 1/32 f-350 body is very short



quck mockup
the body is from tamiya 1/32 juggernaut ford f-350
the tires are from tamiya 1/32 isuzu mu



finished assembling chassis




finished assembling chassis and axles




quick mockup
feel like to change the wheels though...

any advice would be great
thanks
