For Sale: Parts bin single speed hack MTB

First post!
I know it's a bit random of me to post to this thread and for all I know everyone has stopped reading it by now, but here goes:

I am trying to work out the solution you are using for the front crankset/chainwheel. I am currently doing my best to convert a MTB to SS and I am struggling to find a single chainwheel solution for the BB.

Looking at my MTB frame it seems that the chainwheels have to protrude quite a bit to avoid crashing into the chainstays, which means I am forced to stick to the heavy and ugly 3 chainwheel crankset that came with the MTB. If there is a way around this please help me out. I've been looking for threads on this topic without much luck. And perhaps someone could mention some product names?

Thanks!

I got around this problem on an MTB conversion by using the original crankset and removed the inner and outer ring then used a cassette rear wheel with a converter from Charlie the Bikemonger. you can jiggle the chainline to get it spot on. the kit is about 17 quid. the cranks dont look great but its functional.
