Anyone got any ideas for a simple chassis jig for a one time build? 150" WB.

Glenn, I copied both of those pictures to my computer, both are kinda more  in depth than I wanted to do. I'm big on ideas, and small on shop space.  :D That's why I'm kinda leaning toward something I can break down later without much hassle. A different picture of rooman's gave me the inspiration for building a tear down fixture instead of welded. Noticed his use of washers to level a lower rail in the jig. Figure truing up a bolted  jig was possible using the same idea.

John, I won one of the CENPEN $2K prizes toward a chassis in the last contest. After a lot of thought, I passed on it. The biggest reason, I want the experience of building my own. I appreciate the offer though.

It is either straight or it isnt. Worked well. I could clip the tubing in with HD rubber bands and fit all the parts  and then cut it free when done.   Have lent it out twice to others and gave it to a fellow north of here as I had mistakenly thought I had done my last build.

The Mark William's website has pictures using TJI engineered wood I joists for a jig.  ;)

Don, I'd add that you've inspired me to build my own having seen your posts here and on the HAMB. Your builds remind me of the way it was done before everything was available for purchase from a catalog.

this is mine .  1/2 plate , 24" wide 18ft long .... has 6" c channel under it to keep it flat .....i built mine for a 1 time use i have stuff welded to the table to hold the tubing that ill later remove . but if i was doing a production run it would be alittle different . but for me it works great

I did the same as 225 . . . didn't make a jig, just used a table and tacked angle pieces as needed to clamp to.

Mine is 137" WB
