Mark And Duncans R32 Build

[haw001]

Where do you want to leave it, Sydney or Melbourne? Sydney I can't help out for long, the front yard has to be cleared for when we move out in Jan. In Melb you could leave it at my warehouse for a while if you needed. It's lock up, but no guarantees on security. If pieces go missing, I may be responsible, but I won't be held responsible

Not sure, Sydney would be best but im trying to store it for cheap longish term. I very much appreciate the offer, will most likely take you up on it, just need the car to be ok then ill get my name on the papers and go from there

Either way ill be in touch about the bonnet and front bar as soon as i know (by Sunday night)

yeah Brad mid (to late) Dec would be perfect. We sealed the motor last night (old mate of yours, Mike did it for us). should be right to put it back in this weekend or next depending on when I have to work. what event do you have in mind?

Steve....if you need to use a trailer and can bring our stuff back I think we can sort something out

Excellent. Oh yep Old mike and I go WAY back.... as im sure you probably would have heard about. Damn he can talk, and talk, and probably talk a little more.

Never ask him about his old N13 pulsar! I made that mistake last time he was here sealing up the combined touring car engines. Bloody hell!

Nicest guy you'd ever meet though and providing you fill him with coffee and biscuits his happy to come out anytime.

He actually lives two minutes from my place so also kinda handy.

Ill call you re the days im thinking about doing.

Also guys have you sourced your cage material for Marks other car??

Im buying all mine in this week and have secured a really good deal on the amount I need.

Ill be doing the entire cage in the better grade "chromoly" purely due to the weight and the fact its working out cheaper than buying Mild steel from the old supplier.

Im taking the car trailer to pick it all up over the weekend if you still need material you welcome to join in.

I bought the steel last week. Where did you manage to find the cheap stuff, and how cheap was it. The Chromoly that I bought was marginally cheaper than the equivalent mild steel, but it still was not cheap.

big sprocket = small top speed. small sprocket = big top speed. hence for a car sized track you'll be wanting a smaller sprocket not the biggest one you can find...

you sure about that?

i'd have thought having a large rear sprocket would give me a higher top end??

[benm]

Think about your mountain bike when you were a kid, big rear spocket for steep hills and small sprocket for going down hills

Sorry tiger but BB and Benm are right.

My Radical runs a chain as well. I don't change my front sprocket (17 teeth) rears are as follows,,,Oran Park GP (48 teeth),,,Eastern Creek (46 teeth) and Wakefield (50 teeth).

yes I am sure!! but try it if you don't believe me!

/waits for 1 of Duncan's brilliant MS Paint drawings....

Someones been on the turps tonight.

Please no naked flames.

It a health and safety issue kindathing.

I lol'd

[Angus Smart]

Haha thanks guys, now that i do think about it you are right. i was thinking bikes but obviously not thinking right.

i wont be changing the engine gear, only the rear but i will try put the biggest engine gear i have on.

i will have to ask the go kart shop what they'd recommend.. but i cant see myself getting off the throttle at all with the current gearing

p.s. i think you need to add a commodore badge to that thing you posted

Mark I got enough material to build atleast 3 cages similar to yours (two of the one Im doing) all in the highest grade chromoly the supplier has for a 3rd of the normal cost.

We roughly added it up to well over 100m of tubing in each size.

I also got the MDS (material data sheet) with it.

bkes, carts, cars all the same. you've still got it backwards though. for car sized tracks you will need a smaller rear sprocket. not a bigger one. think about this. if you have a small gear driving large one the small one must rotate many times for the large one to complete 1 revolution, it's easily worked out and that is the final drive ratio. so in a GTR for instance the diff input will spin 4.1 imes just for the wheels to turn once. yes you wont change the engine drive, there is not normaly any need to. in karting you can get a wide enough range of ratios just by changing rear srpokets. I think you need to go back to school big buddy!!

Apologies in advance if I've missed it somewhere, but if you guys are going to build Moly cages won't you need an engineers certificate for CAMS? And don't they run to 3k plus these days?

Yeha i figured it out i was thinking bigger for some strange reason. but now i remember from my old mountian bike which i've not riden in about 50 years! haha

tho i think i'd need a bigger engine sprocket, then perhaps about 10-15teeth smaller rear one. its going to be a C^$t to start!

Way too much on my mind latley with all this starting a business shit going on.

no, just leave $50 inside your log book when you get scrutineered at events. much cheaper than get it certified.
