This basic tutorial will cover cutting a simple 90 degree fishmouth into round and square tubing. A fishmouth is a semi circular cut taken at the end of a tube so that it can be joined to another round tube. In bicycle frame building, it is often necessary to cut several fishmouths into the ends of the steel tubing where the head tube or bottom bracket will be installed.
“So I took the plunge yesterday and started my Highroller. I’m doing things a little different than the plans, but I think it will turn out ok. If not, I’ll make it ok!
I am using the seat stays and chainstays from my donor bike. I’m currently working on boxing in the chainstays where they meet the bottom bracket. I’m hoping that it will be strong enough once I am done. I’ll be posting pictures of what I’ve done so far.”

Mini bike chopper from Russia “Hello. My name is Aleksadr. I am from Moscow, Russia. I send you a photo for your gallery of builders. It’s a mini chopper I made for my son for school. I will be very glad if you put our mini chopper in your gallery. Viewing your photos has inspired me on construction of it.”
“Hi Brad/Kat. Thanks again for the inspiration.
Having bought a few plans, in the process of completing my quad with 2 wheel rachet drive, I got a copy of the Bike Bonanza Book.
So after 2 days effort my son now has a KoolKat recumbent.
Such an easy build should be recommend as the starting pint for everyone, as it is very pleasing to get such a good result so quickly.
Thanks again. Please post the photos if they are suitable. Kind regards, Tim aka go1000go.”
“Hi, guys and gals. My name is Amos and I’m a Zom… newbie with about 30 sec. of stick welding experience (which was 5 or more years ago) who’s chomping at the proverbial bit to make himself a custom bike. (BTW, are all members of the forum considered Zombies, or just those who’ve completed a bike?)”
