What do you think of my sprocket guard?

[gtt416ex]

i made it today in metals class. just 10 gauge steel cut out with a plasma cutter in a circle jig. when i got home, i painted it with truck bedliner.

it only took about thirty minutes to make, i plan on making a couple of more and i might make a dual guard (one on each side of the sprocket)

looks really nice. i would make sure it is balanced nice so that it doesnt make it vibrate at higher speeds. this could also cause premature bearing wear too. i bet it is really close though, if you have a tire balancer you could probably do it on there. steve

i don't think that it weighs enough to make it unbalanced, i've already spun the axle around and it doesn't have a warp or anything in it, straight as an arrow. thanks for the advice steve

you could start making them and sell them. i would consider buying one. you should make a nice setup for the rotor too. just make it mount to the caliper mount. it would be sick. steve

i'm really thinking about making about 10-12 of them if people are interested, this one will work for 40 tooth or smaller. i found a rotor wing off a dirtbike in the trail monday i'm thinking of making it work somehow. lol

maybe not. run it down a road and see if it vibrates at all. it isnt thick enough to mess with most likely but something to consider if you start making thicker ones. I would say a 3/16" one would be really nice. that looks a bit thin at 1/8" and could possibly dent or bend and start to rub on the chain causing it to rub and possibly break the chain if it hits hard enough. I would use a 6061 aluminum that is 3/16" to make it a bit lighter and just about as strong as the steel stuff. steve

that's the next one i'm doing is 3/16" steel, i'll drill holes in it to drop the weight down and make it easier to clean

NICE make sure you post pics of it when you are done. if you have a lathe at school mount it from the middle and clean it up on the outside to make it true all the way around. steve

alright it may be next week till i get it finished cause its supposed to snow tomorrow. but i'll definitely post pictures
