corrupt Posted May 8, 2007 Author Share Posted May 8, 2007 we buy heaps of stuff from them through my work, EDL is also good for boltsI didnt really read exactly what your doing but could you not buy some rod and get it threaded, or even buy 12mm threaded rod and cut it to suit? im sure i can get a better bolt off the shelf somewhere, will ring these cunts tomorrow and see.

kyteler Posted May 8, 2007 Share Posted May 8, 2007 Forget your bolt man, an unbalanced pulley on the end of the crank is going to cause nothing but drama. At the very least take what you've fabricated yourself to a engineer to get it balanced. Quote Link to comment Share on other sites More sharing options...

kyteler Posted May 8, 2007 Share Posted May 8, 2007 Anyone who does flywheel's, driveshafts etc, would be the go. Quote Link to comment Share on other sites More sharing options...

V8Pete Posted May 8, 2007 Share Posted May 8, 2007 A place I worked at used RAT (Rotational Alignment Technologies) 0800 254 4648. From memory it was something to do with long shafts, but probably involved balancing too. Then they stopped getting them balanced/aligned at all, and nothing broke Wasn't going as fast as a crank pulley, but. Might be worth ringing, but as ^^^ said, there's probably one that specialises in automotive applications. Quote Link to comment Share on other sites More sharing options...
corrupt Posted May 9, 2007 Author Share Posted May 9, 2007 they stopped getting them balanced/aligned at all, and nothing broke Wasn't going as fast as a crank pulley, hmm im one of them tight ass cunts, someplace prob gonna wanna charge me a pocket load to even look at my arc'd together pulleys if it is out of balance what are gonna be the side effects?

Chrome_GT Posted May 9, 2007 Share Posted May 9, 2007 Hey, Another problem you may have is eccentricity. You mentioned you lined them Up but get it checked out. With bad ececntricity you'll get bad vibes when running the belt as it will be tightening, loosening, tightening, loosening .... every time it turns.

blakamin Posted May 9, 2007 Share Posted May 9, 2007 if it is out of balance what are gonna be the side effects? Fucked belts, fucked bearings, vibrations..... Quote Link to comment Share on other sites More sharing options...

Gaz Posted May 9, 2007 Share Posted May 9, 2007 The whole engine will be out of balance. Extra strain everywhere. Id just get it done properly instead. Quote Link to comment Share on other sites More sharing options...
peteretep Posted May 9, 2007 Share Posted May 9, 2007 look into how other people have set-up their superchargers? what do the other guys do? Quote Link to comment Share on other sites More sharing options...
corrupt Posted May 10, 2007 Author Share Posted May 10, 2007 took the pulley to this good cunt at a engine/driveshaft balanacing place he reckoned it would be sweet as balance wise, and everything looked good on it to be able to use it. he also said that balancing of this pulley would be the least of my worries, as the rest of the engine isnt probably in balance to start with. then he noticed a crack beside the keyway on the factory pulley and suggested that i got another couple of pulleys and redone them this time maybe using a mig welder for a tidier weld. thats what ill be doing once i get the setup running mint.

Burntrubber Posted May 10, 2007 Share Posted May 10, 2007 You wana be careful welding cast have to use the right electrodes or wire if you mig it. Quote Link to comment Share on other sites More sharing options...
corrupt Posted May 10, 2007 Author Share Posted May 10, 2007 You wana be careful welding cast have to use the right electrodes or wire if you mig it. when i arc'd these ones together i used mild steel electrodes, and its mint for strength, so probably just mild steel mig wire?? im gonna be borrowing my mates mig so will have to get the right wire etc Quote Link to comment Share on other sites More sharing options...
Burntrubber Posted May 10, 2007 Share Posted May 10, 2007 Um I think you will find that mild steel rods are not really the best for cast you really need a high nickel rod for that sorta thing. Also should pre heat it but then again I've done a few things without pre heat and they've been sweet. As for mig flux cored wire's have a high nickel content.

crazy_rich Posted May 13, 2007 Share Posted May 13, 2007 8.8 is still high tensile, she'll be right. I doubt the cast pulley will hold, but you might be lucky. Any engineering place would either suggest making a custom pulley or getting your one heat treaded to remove the haz. good luck. Quote Link to comment Share on other sites More sharing options...
Burntrubber Posted May 13, 2007 Share Posted May 13, 2007 Did Sierras have power steering or air con, if they did you could grab a pulley off one of them. Thats assuming its a pinto your working with. Quote Link to comment Share on other sites More sharing options...
corrupt Posted May 13, 2007 Author Share Posted May 13, 2007 the sierras powersteerign used a single v belt, im using a micro v (5) belt as thats what the charger has on it. its all gravy anyway, spoken to an engine specialist he reckoned the custom pulley i have made up will be fine to run and the weld looks to have worked well between cast and steel. will be remaking the exact same pulley as this one has a crack in the cast item which i was not aware of spent hours on it ffs.

QCADTA Posted May 14, 2007 Share Posted May 14, 2007 the weld may have worked but probably left the cast pullet a bit brittle. best way to weld would be to braze it with oxy/acet with a slightly carbonised flame, i think thats what its called from memory. someone correct me if im wrong.
