Chassis build questions
I have been trying to find a chassis shop and it has been something else. I am getting prices all across the board, how do I know that we are both on the same wave length? What should I expect the prices to come in around?
Let me tell you what I want do and you tell me how much it should be around.
Chromemoly or MS
I will deliever my F150 without the front cap, interior and glass
build 10-12 pt cage (replace rubber cab bushings with steel and tie roll cage into factory frame rail)
trim dash and install
install seat
install throttle and brake pedals (mech trottle linkage, wilwood brake dual mc kit)
install & setup ladder bars and floater
c notch factor frame rail for rear axle clearance
fabricate firewall
Drive shaft safety loop
I will have the front suspension

Re: Chassis build questions
It sounds like you have a good idea as to what you want the finished product to look like. Thats a good thing, but be open minded and let the chassis guy have a bit of freedom to put his touch on it. Whatever you agree to with someone get it in writing and take a copy with you. Over the process of building the truck there may be some things that come up that may need some special attention or things that you may decide you want to have done while the trucks already there. Keep an open mind and just let them know that nothing extra is to be performed without consulting you first. Keep in touch with the builder when they have the truck and ask lots of questions. Progress reports from the builder keeps both parties motivated.
As far as prices go thats a can of worms that has may surprises. Cheaper is not always better as with most things and more expensive is just money out of your pocket. Its all about the bottom line and getting a product that you are satisfied with. Most of the bigger shops around here that do mostly larger scale stuff like full tube chassis cars and such charge way too much for the smaller jobs in my opinion. But their experience and resources are far greater than someone like myself who does it part time. So in the end dont compromise your budget and or the quality of the finished product. Brian Spears

Re: Chassis build questions
It just seems hard to get my idea through to the shops and of course any of their input would be greatly appreciated.
Example: acouple of the shops suggest I go with a funny car cage system which I would like as long as I can get in and out. My origonal plans where a full 10-12 point roll cage and then add a funny car cage later.
Another thing I am wondering about has been their welding skill.
Since no one is local it makes it hard to show up at the shops and just look around. unless ya'll think that might be a wise thing for me to do.

I think that is an excellent idea. Even though you might have to take a day or two to do it, I think it would be very beneficial to your peace of mind. If you don't like what you see, keep looking until you do. After all, it's your money. Spend it wisely. Nothing worse than getting a car back and being unhappy with the workmanship.

Re: Chassis build questions
Josh,
I can go to 3 different "shops" here. Mostly it's just guys that have shops behind their houses and do good work. They'll all give me 3 different prices all across the board too. I'm talking an almost $800 spread!
Don't have much more advice other than pick a guy based on his experience, quality and skill. Pay his price...

Re: Chassis build questions
We were quoted over $6000 on our last upgrade so I bought a Tig welder, and all of the other notchers/benders. Did it ourselves. .

Re: Chassis build questions
There is a guy near me that has been building racecars for years. He is pricey and can be slow but his workmanship is better than I have seen anywhere. His shop is spotless and he is always busy. You often get what you pay for. Much of the price is the knowledge that is built into the job.
You need to see the work they have done and talk to past customers. Talk to other racers in your area too and see who they recomend.

Re: Chassis build questions
I talked with another local shop owner today at the race track. He was busy at times but not just covered up to exchange information. Yet I got the cold shoulder. I just asked him if a project like mine is something he would want to work on. Because I don't want someon working on my project if they are not into or just feels like it's a pain in their neck.

Great customer service eh?? It seems to me you need to be able to get along and communicate very well with your chassis builder.

Re: Chassis build questions
If you can't do the work yourself,most times it's alot cheaper and less headache to find you a chassis project that is finished and buy it.

Re: Chassis build questions
What are your skills??
NOBODY, is gonna care about it as much as you. There is a ton of info online if you look around. buy a welder, some tools and go at it. We can help here for sure.
First ask yourself how fast you wanna go.
2nd budget.
Then design plan it to those parameters, engine/vehicle weight, and go from there.
Regards.

Re: Chassis build questions
My brother and myself have built a tube chassis car before, back in the 90's. It was a simple NHRA spec cage nothing SFI. We borrowed his employers tube bender and a little 110 wire welder.
I own a nice 220v mig welder and like to believe that I have possablility to understand what is needed to build the cage myself. The only reason I haven't attempted to do the project myself is due to the cost. Once I purchase a tube bender and die (JD2) that's a $1,000 pretty much gone. Then the wisdom part. I don't know and can't figure out the best way to tie the cage into the frame. I know I will have to replace the rubber bushings that isolate the body / frame with a soilid bushing.
Just seems like it would be worth the money and craftmanship to let a chassis shop do the work.
