I might weigh them if I remember

Alloy ones tend to be around the 1.5 - 2.5kg mark. Really depends on what you get.

Thanks cyclons8.and roughly how heavy do the stock a-series rockers weigh?would appreciate if you have that info datto_man.Sorry to go off topic on the thread.

cheers

Chris,
Do you have drawings?
I will be retiring next year and have the gear in my shed to make the pattern and corebox for sand cast.
I have been modding some patterns for a histerical race dude up here in Sydney for Elfin mag wheels, the patterns suited from 6 to 14 inches wide and he couldn't figure out what went where. Had to turn up a few bits but their now at the foundry and ok.
Do you have a tame non-ferrous foundry down there?
I have lost contact up here 'cause so many have closed.
Can probably chase up the one being used for the wheels once I retire.
Bumped into the last TAFE teacher recently he said there is 1 patternmaking apprentice in NSW and he does block release in Qld.
Illawarah TAFE has the foundry set up, don't know if they still have the classes for non-trade anymore.I went in the 90's and they had steam nuts,car and bike resto bods and sculptors,they would only pour what you could lift in a 2 man ladle. Induction furnace would melt cast iron in 20 minutes. If any one is going to use 3D stuff for patterns don't forget draft and contraction.

I have heard good things about Matilda Foundry in various places, they seem to do everything from pattern making to small production runs..

hava looky at these see through rocker covers

Oh I love clear rocker covers, and clear dizzy caps. If only you could still get them...

we live in a cruel world these days none of the oldskool stuff is easily available any more :(

If any one is willing to fabricate one for group sale, I can assist with CAD drawings
