Use a grinder with 1mm cutting blades and if you can do a V cut, slide in a close fitting section and rose weld it inside, then slide the new section on, do some rose welds there also and lay a nice bead in the V groove where the 2 meet. This way you have more weld area for strength.

TT & Wills 670
Your feedback is exactly what I have been looking for. The photos help alot and what Wills has done is what I will be doing. Most likely in the same location. Any further advice on what to look for would be appreciated. Wills 670.. I see you had a jig system set up.. was this to hold the frame and how did you cut yours? As well as did you mig weld? Any thing that can be provided would be greatly appreciated.
Best regards,

I used the jig to hold the frame still. The channel was leveled and then I used concrete fasteners to bolt it to the floor. I took my time and used a sazall to cut the frame but a cut off wheel on a grinder would work better.
I used some alum. strips about 4 inches wide to make patterns for my cuts. That way both cuts on each frame would be the same.
I used a mig welder for my welds and v groved the butt ends and drilled 1/2 inch holes for the plug welds.
Here is another pic. of the jig. If you will notice I made the rear part where it will unbolt from the frame and jig. If you don't do it this way the frame will not slide over the inserts on the inside of the frame. You need to make the inserts tight fitting on the inside if the frame. Also take your time welding it you do not want to get it too hot it can warp.

Frame cut
This might sound like overkill...but my friend in PA, who owns a Corvette shop there, Gee's Corvettes, bought a gas powered cut off saw when I was with him one time. You know, the ones with the 10 to 12 inch discs on them you see construction workers cutting ashphalt with. He said it's awesome to get a really straight cut on a frame. Makes sense to me.

Yet another question... I have received my donor front frame 1/2. Should I have this section sent to a frame shop to chech for straightness prior to the grafting process? My mind says yes just to ensure that it is true prior to trimming and welding to the back 1/2. My concern is if I don't my measurements will be off. Advise please.
thanks
