Building your own chassis.....
Today my father and i took a 4 hr trip to Sacramento to watch my friend graduate from the CHP. Anyways we started talking about what i would like to do and accomplish with my truck. After a long conversation my father says "Why not just build your own chassis". That got me thinking. Could we do it. I do not have alot of experience with frames and suspension but my father has done some chassis building and tons of work with classic cars. My dad built 2 quater mile dragster chassis himself and is a certified welder with all the necessary tools to make one. On the other hand all of his chassis that he built are little different than one for my truck. My question is does it take a rocket scientist to build a custom frame? I am very tempted to tell him "Lets do it" but want to make sure i know what i am getting myself into. I am not really worried about spending money to build it but just being able to forsee everything that needs to be addresed ahead of time. If that makes sence. Does anyone have any comments or tips that i should know ahead of time. Also if anyone has some pics of some custom made chassis that would be great.
ps. I am aware that i will have to build a frame table. Also it will be for a 1970 c10 swb Thanks ahead of time Josh Last edited by abadsvt; 09-09-2006 at 02:58 AM. |

Re: Building your own chassis.....
Are you all gonna build it stock? or set-up for air so it can be slammed easy?

Re: Building your own chassis.....
i am not a chassis builder but i did weld in my first atempt roll cage. the cage turned out great but i didnt have a good enough welder or equipment so it had to be cut back out. my problem in welding it was the spot above the head on the main hoop man i had my mig hose bent to tight to get in there and i did not understand the rules as far as width of weld so after 3 passes i had it all messed up. i had a pro do it the secound time. my cage was a lot better fit than the one he made. probalbly cause i did it for the love of my truck and he did it for the money.. I am slaming mine to the ground with rear coil overs going to have to cut the frame for rear axil clearance. up front i am going to build a mustang II crossmember from scratch i have read and talked to people on the bord and done my own research.. using after market a frames i am going to build it making the shafts parallel with one another looking straight down on the suspension.. the other critical area is the bump steer. placement of the rack is critical it must have the nuckels or the point of bend with the outer tye rods placed in line with the uper and lower aframe a axcess point. last but not least is the amount of tilt on the uper a frame you put into it. factory is 3 degrees but alot of aftermarket companies put none or little in at all. from the engineering books i have read you will have less stability problems at zero tilt.. i got a lot of geometry info from heidts.

Re: Building your own chassis.....
This was what i was hoping to here. People sounding positive that one could do it if he does his homework first. Thanks alot. I think i might check out that "New Classic Truck Mag" to see that chassis.
Now this is what i am thinking. I haven't removed my frame from my truck so i will know alot more once i get a chance to disassemble. I was thinking about using the stock frame for all the measurements but modify the rear section so it will sit on the ground. I have another question. For those who have built or wish they would have built a frame, is there anything you wish you would have done different or changed? Thanks for the help everyone and i will DEFINATELY keep everyone posted with pics of the progress. Thanks Josh |

Re: Building your own chassis.....
I was just looking at the chassis in the mag and it has a lot of nice features. Not sure why it bugs me, but it does to see the Ford 9 in there. I understand they are cheap and sturdy, but why not use a GM rear?

Re: Building your own chassis.....
My dad and I were just having this conversation last night about ford 9" rear end, Chrylser 8 3/4" rear end and Chevy 12 bolt. I forgot why but he ended up saying that the ford and chrysler are more solid and stronger than the chevy one. The chevy one works but to change the gears you have to work on the rear end in place where the fords and chrysler you can remove the housing and work on it on top of a work bench. Something like that. I am sure someone will chime in. I am going to go buy that mag right know. Thanks Josh

Re: Building your own chassis.....
I would think a better frame could be built if you do your homework.You could use square tubing and build it to stock specs or you could use ladder style rails.I would suggest getting a book on suspension before starting so you have a guide on what things are important to consider during the design of the frame.Also, remeber your Dad built dragster chassis,which have to be strong but do not have to handle well.The same principles will apply but need to be adressed differently.

ABADSVT,
I think I will keep your father in mind if I ever build a pro mod 63 nova.

Re: Building your own chassis.....
Sounds good Jugernot!! My used to be pretty big in the quatermile dragster world. Some of the people that he knew and worked with were among the best in the world. Have any of you ever heard of HOGANS MANIFOLDS? http://www.hogansracingmanifolds.com/ . My dad helped him design and build most of the stuff he still sells today. They used to be really good friends. I don't remember much about him racing cause i was too young to remember much but man do i love racing! Its wierd cause just the smell of the cars running alcohol gives me chills. Anyways sorry for braggin about my dad. I will keep you all posted when i get ready. Thanks Josh
