Over the last week I have pretty much been doing the same as what I have been doing for the last 2 weeks, CAD. I’m so ridiculously over it. The model is really coming along well however I didn’t anticipate there would be so much work. I have been CAD’ing every component well and accurately it just turns out I have literally hundreds of parts. I really hope to have this done by the end of the week as I will be heading back to my dad’s shed next week to complete the scale model. Everything is falling into place. With the last of my car body being CNC milled. I will also complete this week so that the model can be completed. If all goes well I should have a fully constructed model by next week. Then I just have to send the appropriate components off to be objet printed. All is on track it is just so much bloody work…. Below is a CAD pic of where I’m at.

Over the last week I have still been fleshing out my design in CAD. It has been slow progress at the moment mainly due to the construction of the tray under. The bellow images depict where I’m currently at. All the components are to scale and the brace sizing etc is all designed using available steal sizes and thickness. The tray bracing system is modelled on the current DSE

For my project it is crucial that I know the industry steel standard sizes. I simply just googled this and found a couple of links showing what steel is available and a what size. The bellow links show both sheet and long section steal. These size will be important for the CAD model.

Sheet – Edconsteel

Bellow is a great link explaining a plastic composition and a method to making solid parts directly into the rotomoulding process. This process may be handy for screw lugs etc…. Great Link.

So using the chassis model I have been able to determine the exact shape and size of the tank. The render below shows the tank. Using the volume calculator in solid works I was able to determine its exact capacity. The tank is 4ooL in size. I am still continuing the development of the baffle system.

As mentioned in the previous post, I am developing the CAD to level that will allow me to develop the final design of the tank. The CAD image bellow is a complete design of the chassis parts that will directly effect my design. This and several other drawing views will be used to accurately develop my tank.

CAD Landcrusier Chassis

Yesterday I took another visit to the Mansfield DSE depot to document the underside of the DSE’s Toyota Landcrusier. As my design reaches conclusion I have now found that I am a point where I must complete the CAD work of the final Landcrusier chassis in order to accurately complete my design. From the research I found that I know approximately how I want my tank to fit and be designed, but in order to calculate a final size I must completely construct the CAD so the tank can be measured accordingly. The size of the tank is important as requirements specify it must not be any less then 400L. The amount of area I can use under the tray will directly determine the amount of space taken above the tray. I will continue this process over the next few days to reach my aim of having a completely refined design by class next week.

Below are a few images that I have taken to document the underside of the DSE vehicle tray.
