Well after a bit of though and a look through the stock box som stainless steel bar was found and some mount printed to attach it under the trailer bed to provide attachment points. These are definitely a work in progress as i intend to revise and fit let side makers to them for MK2



Temporary fixing with double sided tape for testing



This now means loads and equipment can be secured for trans port to the job site and delivery at the club.

After discussion with a friend he advised on a design for a load strap see below thanks Fred



Which enables the securing of the loads









RC Skidsteer ready to be transported to the jobs site
Please give feedback on the look of the load straps

It's a little slow in my opinion... Maybe I will try the higher RPM motor down the road... For now, it's on to modifying and mounting servos!

I modified the transmitter and took out the spring mechanism on the one stick.


I modified the bucket curl servo to get more travel. It runs about 160 degrees now. I soldered in two 2.2k resistors, one on each side of the potentiometer. I also moved the wire to the side of the case.



Video of servo travel. You can see where I marked the cardboard stock and the new travel.

I was able to keep the engine cover by mounting the servo low, and cutting it out for the servo arm and linkage.


I mounted the lift arm servo to the model with 1/4" aluminum blocks, they are drilled and tapped to mount to the servo, and on the side to mount to the model.

The bucket servo is mounted with SteinHDan's 3d printed mount I ordered from ShapeWays. I modified a small servo arm to fit on the bucket mount, then drill and tapped the arm for a 4-40 screw. I drilled the pivot point for the bucket so I could screw an m3 screw into the servo gear.




I mounted the receiver under the cab and had to cut out a bit of the seat to get it to fit.

The BEC is mounted behind the cab in the main compartment above the motors.

I had a hard time finding a battery that would fit because I mounted the servo pretty low. I ended up with 2 x 450mah 2-cell li-po batteries, wired in parrallel.




How it sits now, almost done.


Video of it running:

It seems to be very stable, I don't think I will have to worry bout it tipping.

I may try to get a little bit more travel out of the lift servo, I feel like it is not lifting all the way up.

Thanks for looking.
-Kyle

I already have the grapple and the last few weeks i have been workin on the live heel ,boom and stick...Heres where im at now




a preveiw of the boom on the machine...Pretty long over 39 inches...Trying for the 2554 witch is 46 feet so im in the ball park...looking over stats from the 3554 and it 54 feet...gona take quite a lowbed to transport






A bit more progress this weekend ...cyclinders are mounted and a bit more detailing..Gona get strated on the hydro piping soon

These tires are 130 mm dia hollow and very well made ...i may have to do some mods on the ADT if i want to use them.




Yesterday i managed to do a lttle testing and threw a load on the pacific...Dam forman showed up and parked his pickup next to the truck before the binders were put on..





did make some more progress on the cab..I got it properly mounted with a hing point wich will make it legal to haul on hyway...I can hide a bunch of electrical and keep it away from oil leaks...I also made steps for the operator

back in the grind of build again ..something different this time ..Rob and Greg are looking at hiring a screening plant so heres a little preveiw




Thanks Mog ..Im just going to use a regular 1/16 strip of rubber and leaving the bruders as they are..well its functional and turning ok ..Using a 30 rpm servo city gear motor and that seems to be just right ..Rob tested how much current its drawing and it doing fine ..ran it for about an hour after fiddling with the tracking ..if you look closely i have adjustment on end rollers for both ends ...I use my little Poxom mini mill to make up the belt coupling and a short chunk of cable with a couple of wheel collers




is pretty much my first trummel build and im using a pretty heafty gear motor to turn it ..motor seems to be working fairly hard but we will see when its loaded full of dirt ..I remember my fathers big unit about a 7 foot diameter tube was really struggling when fairly full..We even twisted a drive shaft a time or three ..that little izuzu diesel was smoking pretty black ....Gravel mixed with water feeding sluice boxes ..Water probably helped keep the friction down ..wonder if turning dry gravel is a bit more difficult

this is the unit that inspired me to build it this way

[QUOTE=tracksntreadslou;92982]I also started on a ripper ..nice having a cnc to cut parts






I found a new home for the new tires ..wasnt that happy with the mamoth tires on the hitachi ADT so on the workbench it went ...while it was there i started to do some mods ...I moved the dump cyclinders back almost 3/4 of an inch ..think i wont get any dirt hangging up in the box now ..wasnt much but it bugged me ..I also made up a tailgate ..still a few more parts to mill but it is coming along

Thanks everyone ..appreciate all your input ..tom i was pretty much the same way ..took me a while to find some good enough pics to show how it works and luckily once my cad was machined the geometry worked well..I will be able to steer at around 85 degrees heres a few pics i found



And i received a package ..couldnt wait to get started


was having some problems with photo bucket last night so now heres what i got accomplished on the weekend

I am using Pololu 99:1 geared motor as my drives and at 7.2v it should produce about 200 oz/in torque per motor.
First I made an axle to connect the motor to the drive wheel and hub.

I want to test it first and perhaps add some different grousers. I need to make the orange flashers and clean up some wiring and painting/weathering and it will be fully done. In the meantime here are some almost finished photos.

So I am going to try to make a track tensioner.

Here is the result...much better I think!
