conical pinion and gear set up

the new black arrow car has a conical pinion and gear set up. is it like the old brass setups or is it to get perfect gear mesh with a normal toothed crown gear. or move it off centre. is there an advantage over the old brass setups, where you have a lot of contact area. john

hy, ive got a hypoid crown gear thats running with a 3/16 offset and a paralell pinion, and its whisper quiet. using the old *** paper to set the backlash. i,ve also got a brand new o/s 3-1 bevel gear and pinion with a 3/32 bore and 2mm pinion. that i,ll use on an indy offy body that i,ve got. 300, i dont get the bit where you say" that means the pinion teeth can only be the correct size for the crown at one diameter". you,ve lost me a bit there. could you elaborate for me. i know slot it crowns arn,t strictly speaking a 48 pitch, but with clever engineering to allow different tooth pinions in the 5.5mm dia to mesh perfectly well. i believe that a conical pinion on a normal crown, allows you to run a certain amount of offset, is that right?. john
HY 300, IF YOUR TALKING STRAIGHT PINION MESHING WITH CONICAL GEAR I UNDERSTAND,IF NOT I,M REALLY CONFUSED! does anyone know about using a conical pinion to offset the crown gear john
Its a bit sad really. anyway! does someone know the answer about using a conical pinion to run an offset on a standard crown gear. john
hy Eddie. the link to abslotsport was exactly what i meant and also answered my question. thanks. even the gear sellers recomend different pitch matching. bit beyond me, that one. but i,ll tell you what doesn,t match, an 8t 48p pinion to a 50t 50m pitch sidewinder gear as i tried that combo with a 46000rpm king motor in a carrera 1/24 hot rod. john
hy Mick, i didn,t understand about pitches on gears like i do now, i just assumed it was standard 48p not the metric gear which was on it. it had a tight spot then seemed to jump a tooth. it was just an 8t pinion[brass] that i,d taken of another car. i,m interesteded in what make of 48p pinion 10t will mesh with a 37t metric gear[like scale auto ect] i,d gues it will be a 5.5 slot it. thanks in advance. wrong again fw14. you can read the question so why not try answering it, no matter how much the grammer gets on your nerves. john
whatever!. if you can read my post, at least i hope i provide intelligent usefull information. i dont moan about minor irritating things. which is all you seem to do. you seem to dislike me intensly and i loathe to get in posts when i see your handle come up. but some how whenever i post, guess who posts next.john
Hy Mick, I,m still interested in the metric match. Lets put it to bed now FW14b. john
