? to custom fabricators about elbow

[Mr. Y]

Hello!
I'm going to ask my friend to fabricate large turbo elbow for me, but he needs sample or blueprints. My supra is daily driver, so I do not want to disassemble exhaust many times... May be somebody can send to me blueprints of elbow (stock or custom)?

I hope your help.
Thank you very much.

I can guarantee that most / all of the fabricators here don't use blueprints, they build a jig and use that.

Your best bet is to find someone with a spare stock elbow and work from those dimensions.

Or if it's a one off part for themselves they do it freehand like I did with my trans adaptor (and most of my parts)

 

[figgie]

yes and i doubt that anyone will give this information freely. That is time invested. I hate to say it but you might have to take your exhaust apart.

Good point Figgie!

I do the car thing as a hobby so wouldn't have a problem if I had the prints but if it were my living no way would I send em out!

^^^Ding, ding, ding!!^^^^We have a winnah!! lol!

Information is power.

 

[Mr. Y]

Ok, I see, that you are very kind ;-(

 

[GrimJack]

It's not a matter of being kind or cruel - in this case it's simply a matter of we can't give you what we don't have. There isn't anyone on here (that I am aware of, anyhow) using complex computer operated equipment to put these parts together - it's just hobbyists welding up what works in their home garage. They have no use for a set of blueprints, they just copy and modify the stock parts that they take off their cars.

GJ: I design and make a lot of my gear on the CNC here at home I just don't have what he wants or I'd be happy to send it!

 

[Mr. Y]

I see man, I just thought, that someone measured before or after welding...
no prob, peace =)

On the drawing question....I buy all my elbows from Greg Clark at LIPP. I know for a fact he has complete blueprint drawing along with 3-D cad files.
He builds all his cast products using a method called investment cast process. He has put in a GREAT amount of time and expense to create his products. Just for example...I asked Greg what the tool would have cost if someone would have brought him the drawing to build it...he said it would be over $14,000.
I just got him to sign up on Supramania as Toy-rific. If you have any questions for him feel free to ask on a thread or pm him.
Thanks

Oh yea...if you ask him anything his spelling SUCKS so it may take some decoding.

Good to see Greg here I e-mailed back and forth with him a bit while purchasing my Lipp SS arms!

Very interesting and helpful guy!

 

[GrimJack]

Heh... if his spelling is that bad, we might have some competition for Nash!

No worries, we're pretty good at deciphering posts.

Once I get back from the E-town meet I will post some pics of what the tooling looks like of the elbow and the wax shots to help show the process.
