Building a frame(4 posts)

Hi everybody. im primarily a mountain biker, but i do ride my mtb on roads because i want to do both, but have funds for only one bike. i like the speed of the road. i was thrilled when i reached 40 mph (going downhill) on my knobby tires. it was pretty intense. anyway, on to the topic at hand.
im looking into building my own frame. during the semesters, i have access to welding equipment so i figured i would test my skills on something i love. i was planning on building a road frame, mainly because it will recieve lower impact, but im pretty confident in my welds...at least i will be by the time i have a ride-worthy prototype. anyway...i had a few specific questions.
1. i want to use steel. do i need a specific grade? is there a material standard? or can i use plain ol' steel tubing. steel is real, but how real does it get?
2. are road components different sizes than mtb components? like bottom brackets, steer tubes etc...?

this is basically an experiment to test my welding skills, but i figure if i can construct a decent frame, it may be fun building my own bike on it. if you have any advice, comments or criticism, let me know. if you think im a fool, let me know that too.

You've got a lot to learn. Welding constitutes a small part of the tools, equipment and experience required to build a bike frame.

I did a google search on "bicycle frame building" and got a wealth of information. Check out these sites:

There are lots of folks building frames in their garages. While it's not really difficult per say, it does require some knowledge. To gain this knowledge I suggest you do some homework on the following web sites:

http://www.henryjames.com/

http://www.bringheli.com/

http://www.framebuilding.com/

http://www.sheldonbrown.com/rinard/framebuild.htm

http://www.phred.org/pipermail/framebuilders/

For your first frame I suggest one of the lower cost tubesets that either Henery James sells (OXRCX is very nice) or Dedacciai ZeroUno (sold by Bringheli - my favorite). Considering the amount of time required to build a frame, the material costs are not very much. You should be able to get it all together for less than $100.

As far as the components go, most are similar between road and MTB. The bottom bracket spindle is different, but the frame shell is the same. And road folks are starting to make the move to 1-1/8" steerer tubes so this is common also.

As you might gather, I like to dabble with framebuilding myself. So far, I've built six frames - all lugged steel road frames. I even have some extra tubes I will sell cheap if you are interested. Feel free to contact me if I can be of any help.

Thanks for all the info guys. I understand i have alot to learn, but i figured i'd ask around to see if anyone had any pointers to get me going in the right direction. I'm going to study those sites, and i hope to have something built by next spring.
