For my recumbent project, I have two cranks to choose from and can't decide which to use. No doubt I'll probably end up trying both, but I was just looking for experiences from others.
140mm 40 tooth single
170mm double 39/52 tooth, I think
Is 140mm too small? I see people putting 150's and such on, but nothing this small. Which should I try, at least to begin with?
I had the boom brazed on before but it was quite crooked so I took it off and plan to re-braze it. To do this, I used a file to file down the fillet. Until I got down to the very last bit, it seemed very sturdy. Will brazing alone be enough to hold the boom on? I'm planning on just brazing it on, and if it falls off take another approach, but I'm just wondering if I'm facing imminent failure.
I linked a picture, hopefully the imagestation picture will show up. I won't be using that fork as the seat, but what I have done is put the handlebars down the seat post. I think they will make an okay backrest for the seat.
