Yup! They're quite flexible structures really.

Unfortunately not Hammer! :cry:

I'm in Perth at the moment finishing up a project (refer below piccies) that has sucked all my efforts for the past 3 months....hope to be back in Brisbane Friday night with a view to get stuck into it over the next few weeks.

Cheers,
Danny

I did do one thing before heading to Perth, I got the car down off the hoist and on rubber.

I also fitted the stripped out hard top so that the rollcage design can be completed.

Cheers,
Danny

Ho Lee Shiat!!

I'd love to book a ride in this machine once it's finished... I'll make sure ASE05 and TheMissus let me know when the next meet up is, I'll be keeping tabs on this story for a finish date, and some stats of course!

Nice write up and pics too

It's a Grove GMK-7450....which means that it is a 7-axle, 450 Tonne All-terrain crane. Only the 2nd one in Australia. Melrose cranes in Sydney have the first one.

Yes, every axle steers so that the crane can crab sideways if required.

The Xmas / New Year has given me some time to look at a couple of the key areas of the car that required some design work. I recently acquired a pair of radially mounted 8-piston Brembo monoblock calipers that needed to be drawn up so that a suitable bracket and brake rotor hat (need to determine required offset) could be designed. Here it is in the metal.....

Here it is in Solidworks.....couldn't be bothered drawings the spring retainer at this point.

The next step is to draw up the front upright and hub so that the adaptor bracket and brake rotor hat details can be finalised.

I continued on with the design work by working through a concept for the rollcage. The rollcage has been designed to fit inside the factory removable hardtop. All the primary cage members are the traditional continuous drawn seamless tube, whereas the secondary members are not!

These particular members have been selected because of their superior sectional properties (when compared to traditional sections) for the load cases that they might be subjected to. The cage is a fully welded in item and will attached to the chassis at additional points (to what is shown) as determined to be suitable. Here are some images of the concept.

The mainhoop and rear leg members can be manufactured from the drawings, so hopefully I should strike an arc before the end of the month.

Cheers,
Danny

Stunning work as always, so when are you going to make us NA/NB owners top hats and a pair of brackets for RX7 brakes to fit inside stock NB wheels? :mrgreen:

yeah, and could you make sure that they'll fit with 14 inch NA rims too? ta.

I believe another MX5 Brisbanite is looking into this one...will let you know how he is going. Don't know about the 14" rims though.
