Say I wanted to make my own frame...

[tntoyota]

I have no fab exp. no welder but I feel motivated enough.

Its always been a fantasy of mine to build a Lotus 7 and have not heard you need a table or jig to build it.


So my question is can you make a frame on a garage floor?

How can you Zero it?


If you recommend a table or jig please go into detail and passably link, this (table or jig) is foreign to me.

Some additional words that will never be able to be edited in:




Say I wanted to make my own TUBE or Beam frame....chassis



thanks to whomever made it NOT passable to edit the THREAD title

 

[Mace]

You read the FJ45 thread?

 

[tntoyota]

is that pretty much the only way to build a frame?




I saw a custom J**P frame one time that each side consisted if basically two mandrel bent 3" ROUND tube steel sections that where then bracket (?) welded one on top of the other (picture an over under shotgun ) to form a poor mans frame, Looked like killer fab.........easy to.



I need some truing ideas cause I will not get a table, I know side to side, it's the up and down in relation to front and rear and the accuracy of the base (floor) that I'm worried about.

 

[Marcfj-45]

You can do it ! Use tub beam like this pic.

You will have to weld and lots of calcul....Front,Rear,X

Best luck..Marc.

 

[VETTE60]

truthfuly if you have no fab experience or welding experience, i would not start by building a frame. learn how to weld, and some of those tech colleges actualy have chasis fabrication classes.

This question alone kinda tells me that you have no fab experience.

Go build a bumper and see how it turns out. Frames are not for the beginner.

I know that but mostly I'm trying to figure out (intelligence gathering, intel...) how more or less a frame could be accurate if built on a garage floor, NOT talking about BOX ( X ) or squaring it more like TWIST if you took a piece of 1/4" plyboard and could magically hold it up by one end it would twist in the middle. like a frame flexing or twisting with NO rigidity but the measurements would BE CORRECT because 1: your base was inaccurate and 2: you are basing the only measurements you could get locally 2MK you cant run a tape or level from the (L) rear to the (R) front for level, frames have coutures and because of 1 ....aaawwwwww DAMN!


My Wrain DEtrailed


X & Y TWIST plane axis, NOT A & B squaring or box


HOW on a garage floor do you keep from fabricating in the twist yourself!







Also I want other frame ideas. I had one, a tube frame you can build with a Harbor Freight pipe bender, and weld together with plate!

Is the channel frame the only way to go? Or do you (I) need a vendor every time cause its cheaper than a table?


there has to be more than one way?

Not to be a smarty and I do appreciate the reply but I'm kind of a fast picker upper.........didn't say learner!


to give you an idea about me, I know what a welder is (& notcher, bender, plasma...) and I know what a welder does, I like to think If some one gave me tools I could do anything, however it does me no good to get one if I cant do with it what I want. Call me ambitious but...(I want to build soooo bad!!!)

that might have been hard to build, and cutting edge technology ............... in the 20's


If I have to have a $20,000 jig I'll stop now

 

[Mace]

then go build a frame.

There is no reason you could not build one on the garage floor..

But honestly, from your posts you are strongly opinionated on things that you do not know anything about.

Personally, I would try something easier before you put your life on the line..

 

[Arya Ebrahimi]

Here are two forums better suited for your question.

www.usa7s.com this site is owned/operated by my uncle

www.locostusa.com this site is an excellent resource for tech on what you're looking to do.

I guess I need a jig


I was also looking for Frame ideas ACROSS THE BOARD ideas, opinions, links. I saw the 45 one, my garage is 24x 30, 2 car, NO room for the works (welder, sheet fab tools, plasma, BF'n jig, mount and balance, chop cut, stock & store, motors trannys) oh well.



I think I searched: custom frame & tube frame (I think)

Thanks, I am planing on that.

I have welding DVD's and books (I know) and will start small just playing but ASA I get the temp, penetration and quasi bead right I'll be off like a rocket!

 

[Isotel]

i bet if you had a nice slab of conc that was perfectly level you could make a Crawler frame turn out ok, But Mace is right, there is alot to learn before you jump into that level of fab work..

it would be a challenge to build something like that in a small garage.. Id start with a stock frame and build off of it for your first rig..

 

[Arya Ebrahimi]

If you're wanting to build a 7, there are several options available for pre-fabbed frames and pre-prepped "you weld" frames as far as I understand.

 

[Mace]

Jig is the nicest way to set up a frame.. But it is not necessary.. A good flat slab of concrete and a TON of time with a ruler can get you with a very useable frame.

honestly building a frame is not the tough part.. the hard part is making sure that everything that you are attatching to the frame stays there.. It is the foundation to your truck. Kinda important

you asked for the opinion. and i said "experience", not "fast picker upper". i am saying this because unless you truly understand welding/fabbing you are more likely to "glue" it together with a weld that may look good, but is not truly good.

that being said,n getting in and doing it is the best way to learn because you learn why things fail and how to make them better.

hope that didn't come out wrong


I been being a smart az for so long I cant word the difference,


Thanks Vett60 seriously, I just think people are different and the best way (I could think) to tell you about me was that.

THX RHINO I caught that last night, looking for all the ideas, facts, help, opinions, I can get.
