I've used similar programs before when building bicycle frames. Rough cut using the template and then file to actual size using a half round file. Works great.

A lot of steam/pipe fitters Ive worked around overthe years carry patterns around with them for coping pipe.

Man, so many lost images! I picked up a 650 frame that was braced very similar to what I have seen here. I have it up for sale and the rest of it is stock, but I have the itch now to brace another frame and make a track bike. Looking forward to hopefully snagging that PDF and continuing this project

Unfortunately it gives me a 403 Error as well as saying I do not have permission even with being logged in.

***actually all of the files say that for me. Is it possibly even with an older account I dont have permission to download?

well dammit.sorry man i haven't been able to "re-find "it .

I think I have the pdf saved. I’m away from my computer for a few days but I will check next week

I am having the same problem. I cannot access any of the articles.

I am getting an error that the PDF is too big to upload despite being 2.1 MB. Here is the only relevant page in JPG. IF you want the whole PDF dm me your email

Awesome thanks!
