girder rake and trail prior to frame manufacture
Ok I have a girder (ebay purchase )that i have and would like to figure out the frame rake and trail. when I read some of the posts it seams the frame is already figured out but I have not made the frame yet.I am going to make a low neck height frame. now my question is : what measurements are needed to figure out the frame? I have looked at Nero's post and have taken down some calculations he has made, for his and will measure mine in inches and post my findings.

Re: girder rake and trail prior to frame manufacture
As you may have gathered, thats not an easy place to start. Do you know what frame it was supposed to fit?
Start with a front tire, block the assembled front end at the height you want your neck. Measure the rake and trail, figure out what to do from there.
Thats a pretty crude way to do things, but its all I can think of to help.

We can do anything, impossible just takes longer.

Don't forget to keep the girder links level for set-up,

I started a project build there " File and Fit." I paln to continue that when I go back home in Dec. 2011. I first joined the board when Gary W had it in the year 2005. That was the time I really gained an interest in building chops. I have a long way to go, compared to some here.

I know its not a girder but I believe this is what TattoLeeRroy means.

Those are build log pictures by BarefootJerry. He used to post on the previous site to Choppercompendium. I haven't seen him since then.

Yes, thats the idea. Glad it made sense to someone.

yes I gathered that, being from an automation background I have very little hesitation with doing things the hard way .TattooLeeRoy wrote:As you may have gathered, thats not an easy place to start. Do you know what frame it was supposed to fit?

Y know I have a frame jig and have never used it that way, damn good Id re. with a girder it needs to be design with a 1" load drop when you hook it up to the frame, motor combo so it will sit right. might compress the front end and simulate the load to get an accurate measurement.

Re: girder rake and trail prior to frame manufacture
You could let some air out of the tire to simulate(eq. to 1") if that was easier.Builder52 wrote:[ might compress the front end and simulate the load to get an accurate measurement.
