I like the ingenuity tho. Definitely something i could have seen myself doing when i was younger. Have you thought about shortening your chain? the strength in angle iron is, well, the angle... and since you split one side of it to create the 'dropout', the top half of it will fatigue pretty quickly and fail, especially with how long you have it now.

You win on this one. I will admit to it.

I had initially tried putting the cut for the dropout pretty much right up to the backend of the original dropout and I don't remember what the problem was but I know I changed and moved it further back to give me the room to eliminate whatever the problem was that I was experiencing. There were quite a few challenges along the way. The worst was trying to use a hacksaw for doing the cutting since I didn't have bandsaw to work with.

Not very easily...to say the least. I agree that is the smart way to go.

OR alternatively, purchase a full on bespoke frameset. :D

Trust me the thing that got me started two years ago was seeing DIYWBC(DIYWBC | K&B). I wanted to make it an adjustable frame though. I quickly, initially had the seat tube angle so I could adjust it but I could never figure out how to make the head tube angle adjustable...at least not using any method I would trust to hold up for more than...say...5 seconds...if that long.

Why not use an adjustable stem with some sort of quick release on the bolts that lock in the angle/length?

Changing the angle of the stem does not change the frame's headtube angle, which is what the OP wants to do.

Dude, I hope you don't, but I think this might one day win you a Darwin Award. If you want to get crafty, why not just build your own chain tensioner?

This won't work with a fixed gear.

It could if it was strong enough...

Not a spring loaded one, but a fixed idler pulley would work. It's not ideal, but it's significantly less horrifying than the angle iron solution.

Something along similar lines is already in production Brooklyness I believe is the name of the bike/company that is making it. I want things bit different yet than what they are doing. https://www.youtube.com/watch?v=aZ6o13FPitY

i know youre probably a freshman lib arts student, so i'll cut you some slack here, but building a wooden frame isnt going to make you any less corporate. that is, unless you also plan on making your own wheels, tires, handlebars, chain etc etc.

I also hope the wood you make your bike with is all organic, renewable, pesticide free and chopped down from your back yard and then replaced with a baby tree. cause if not that's bad for the environment brah.

or of course, you could always just go to a local mom and pop frame builder and have them braze you something proper, but that costs $$$

that bike is an abomination on a profound scale. just learn to braze and make your own [steel] bicycle. its fun and not that expensive.

[MENTION=202586]zazenzach[/MENTION] nailed it on all accounts.

OP, just make a fork out of styrofoam and a plywood front wheel and you're good to go:
