locking out mech

Crock - SmP

i've locked out the mech left to right.
but i'm lookign to do it backwards and forwards but dont know how.
seeing as i've made it single speed keeping the rear mech and cassete on but locking out the mech but it keeps coming off the front ring from the slack of them mech.

thanks for the help mike

not really posible. screw in the b screw.

or get a sram one. but if you are doing that get a tensioner.

it can be done i've seen it done on my friends trials but its something to do with the spring you take it out or somthing or twist a thing in the part which the alan bolt goes through to hold it onto the frame.

This may seem weird...
Has anyone ever tried to pre-load the rear mech spring one full turn? Can it be done?

some people have been known to remove the spring on the knuckle joint (attaches to frame) and the C clip position it and tighten.

would that work and lock it in one posistion?

no idea. i would just get a tensioner and not ruin a mech. or live with the b screw fully tensioned and the odd knock.

to be honest i'm not bothered about the mech its just an old deore.
i just havnt got the money for a tensionor and all that at this moment in time so i'm trying to find a cheap solution.

What about what I've asked? Can it be done? Can the part where the b screw bolts be turned backwards one turn thus increasing chain tension?
