I'm learning a lot thanks. Yeah I don't think .3mm will lead to major problems one way or another and I don't think the chain will randomly snag then jump even if the chain isn't lined up because of the larger chainrings being on the outside, meaning the chain would at worst be angled across and above the smaller chainrings of the crankset as the chain runs toward the singlespeed freewheel.

Thanks for the size of the 7 speed chain. I was able to search 3/32" singlespeed freewheel and found this item on amazon. https://www.amazon.com/Sunlite-Easy-Off-Single-Freewheel/dp/B003L9CASC/ref=sr_1_cc_5?s=aps&ie=UTF8&qid=1468904959&sr=1-5-catcorr&keywords=single+speed+freewheel+3%2F32

Do you more or less suspect it will be compatible with this crankset? https://www.amazon.com/Shimano-Acera-28-38-48t-Square-without/dp/B002P71OC4/ref=sr_1_8?s=sporting-goods&ie=UTF8&qid=1468828113&sr=1-8&keywords=48t+chain+wheel#Ask

You've helped so much. Here is a picture of my bike so far. Just waiting on loads of other parts to arrive. https://postimg.org/image/todz6lobn/
