Rack and pinnon style axe parts

anybody know a place that may sell the straight section that would go on the end of the ram to turn the gear? or is it something im gonna have to get machined at work directly into my rams shaft/piston rod

cheers

How long do you need, and what size of ram are you planning to use?

You mean this sort of thing? http://www.beltingonline.com/gears-366/ ... n7ruc22sm7

HPC gears have round rack you can get in different Mods

HPC are expensive fot that, try Trent Valley Bearings in Long Eaton Calum, thats where i go, they qouted me about £70 for a MOD2.5 bit for a heavyweight ram.

60mm bore ram, as for length im not sure yet, its got about 60mm stroke i believe - i can't remember off the top of my head

length i'd say 80-100mm to be safe atm

cheers alan ill check them out, i was making it out of the bits of a pneumatic flipper i made a while ago, to which im going to design properly over the next few days so i'll know more then

mod of gears i was thinking 1.5? that sound about right

are you doing it like THZ with the rod acting as the rack or are you just bolting/welding it on the end? If so i have abit of square rack (i think mod2)

id be just welding it on the end if i can, yeah that would be great alan if i could have that. Going for something basher like in shape with hardox front armour so it can form a team with my spinner if theres tags later in the year

Got a 250mm long 16mm diameter rod, with Mod 2 teeth milled in for 100mm length, maybe something?

If you have 60mm stroke it has some comfortable leeway.

You'll need this gear for 180° stroke

hey, thanks guys yeah that'd be good for me to have of either of you really, are you in the uk can i ask? depending on what alan has, as hes only a short drive away from me as he lives near by.

my rams piston is around 16mm so i can just chop what i need and weld it on the end.
