Does anyone know a RHMT priced source?

No, but I remember Chris M. talk about using cupcack pans to make them.

I remember watching some vid where the guy made metal bowls using woodworking tools on a wood lathe. Seemed like the hardest part would be consistency.

Needing some for the inside of an intake manifold.

I remember a while back somebody posted a site where you can get intake parts.

I'll look at my bookmarks and see if I can find it.

this might work for you.

Also metal spinning a set of velocity stacks would be incredibly hard and costly. Not for the average joe.

It was probably me who posted it.

Yup.

What DIA and height? How many? I would have to make up a fixture for the lathe to do this but it looks pretty doable.16ga anneal and spin.

Will post up in a bit. Waiting on the 2nd intake to arrive. Have to cut the plenum open and measure.

slappynuts · « **Reply #13 on:** December 22, 2011, 09:05:43 AM »

I have a partially done fixture that I am going to give a spin this morning. I will let you know what happens. If it works out well I will hook you up.

The last couple sets of cycle itb's I used the cupcake pans for stacks. They do the job. Some epoxy and some generic filters from the cycle shop down the street and your golden. Stacks for under 5 bucks. Now the best part is going into your local kitchen supply store/wal-mart etc with a pair of calipers measuring cupcake pans. Last time an old women asked what I was baking,lol

Lol I never noticed that. Most non-USA sites tell you their location on their main page.

What would sound better, "DINOSAURS" or "HORSEPOWER"?

This is one thing I have been considering making once I finish building my CNC.

I didnt get a chance to fuck around with this project this morning so Im doing it right now. I will post pics up in a while.

I did fuck around with the shit I had at the shop. I think I need to look for a different alloy though. I was having a hard time shaping it.

Really prone to split? That was what Crazy Dave's dad ran into when he did the Big Power ZC ITBs.

It seems to go well for a while but then it work hardens.

I assume you were just using 6061? Most comercially available 6061 comes in a T6 temper, which mean it won't form worth shit for tight rads. Two things you can do, heat up the material over 400F and let it cool slowly to lose the temper. Or use 5052, which is meant for forming. Some suppliers might even have 3xxx series sheet in stock but I hate working with it, its just too soft.

Makes moresense to form tube...

It was probably 6061 (just some shit from around the shop). I did the sharpie and propane torch anneal.

It's all in material selection. That and having the tooling to be able to form the part.

if you're going to machine something machine a die out of steel to press them on a hydraulic press out of aluminum tube

You're wasting so much material forming those bitches out of solid stock.

Passenger · « **Reply #27 on:** December 25, 2011, 01:45:31 PM »

I was under the impression that we was trying spin them? You won't be able to get much of a radius with a die to form the tube, even if he did do a proper annealing to T0 with 6061 material. Machining them out of solid bar is hardly a waste, Aluminum is about 99% recycleable.
