fusion Posted November 13, 2007 Report Posted November 13, 2007 Looking at making up a custom gear knob for my KE30 Corolla, however I was wondering if anyone knew the exact dimensions? From the looks of things it has a diameter of 12mm and a pitch between 1.75" and 1.5" UNF. Just wondering if anyone knew defiantly . . . Cheers Fusion Quote
ancullen Posted November 13, 2007 Report Posted November 13, 2007 If you're planning on making a custom gear knob, one would assume you have machining tools. If you have machining tools, then there would also be the assumption that you've got measurement equipment of some kind, specifically Vernier calipers and something for measuring thread length. Not sure how you'd measure pitch, but I'd assume there'd be a tool out there for anyone intending to use machining equipment. Try measuring. :) Quote

Cheers Fusion I hope you mean 1.75-1.5mm, an inch and a half pitch would mean you only have one or two turns over the entire length of the thread 12mm diameter is correct though, can't remember if it's 1.75 or 1.5, go with whatever the standard metric thread is for an M12, or just get out the verniers and look really close, should find out easily that way I bored and tapped out an EL Falcon GT momo knob, can't remember what size bore and tap I used though :) Quote
fusion Posted November 13, 2007 Author Report Posted November 13, 2007 Yeah I mean millimeter . . . woops :) The pitch is very close to a 1.75mm but dad the engineer reckons it might nearly be a 1.5mm UNF, main reason for checking :hmm: And I'm getting a mate to custom make one, thats why I needed to check, so again if anyone knows defiantly that would be great ;) Rather get it right than it not fitting :y: Quote

Thread gauge, cost about 5 bucks, super handy tool for prevention of idiocy (eg screwing wrong thread on) "Damn this nut is tight, better get a bigger lever on it" haha Quote
