I've had my TIG for a while now and want to start trying to build some turbo manifolds. I was wondering if anyone has had success building collectors with a chop saw. If anyone has done this can you share pics of the jig that you created? Thanks!!!

 

This was just brought up couple weeks ago:

Thanks alot! I didnt catch that one but its exactly what Im looking for.

 

I've had this bookmarked for awhile

i tried the chop saw thing, its horrible, the material gets a huge burr on it, you have to take it super slow, the chop saw blade's deflect very easily, its a mess, its louder than ****.

do your self a favor and buy a band saw.

 

I don't know what the guy in the video is talking about when he says that cut takes fooooorrever on a bandsaw. I can hog thru that in no time on my bandsaw.

 

talk about load.those dry cut carbide blades as used in that vid are freaking load and scary to run.i ran one in a shop i worked at and i figure i will never use one again.if you have a part come loose with that thing look out because it will end up across the shop.

 

wow, after watching that video, i am definitly using the wrong style blade HAHA. make a fool out of me

 

lol x2

 

X3 where do you get that blade

 

 

i think they sell them style blades at places like home depot & Lowes

 

didnt watch the vid but for those that dont know dry cut saws are not just abrassive chop saws with the carbide blades............ they spin about 1500 rpm slower so just going out and paying 180.00 for a cabide blade is not the correct way to go about it........... even though people do. oh yeah and dry cut saws are great!

technically speaking though, you could just reduce the voltage going into the chopsaw and that will slow it down (maybe use a digital timing light and a piece of tape on the blade to figure out how much to reduce it)....obviously I wouldnt do that for a fab shop, but for the weekend warrior that doesnt seem like a bad way to go about

 

Hah that's my vid. I should clarify a few things:

FWIW that was just to show that if you're just building the odd collector, you don't need any elaborate clamping mechanisms, although obviously if you plan on building a lot of them, an actual jig is nice.

I don't make tons of headers- maybe 5 or so a month on average, but it's enough to justify a jig, I certainly don't do it that way all the time.

That is indeed a dry cut saw, not a standard abrasive chop saw. Concept is the same though- just with an abrasive saw you need to experiment to find a good stiff blade- generally you want them thick and fiberglass reinforced. Be careful at the start of the cut as that where the blade will really want to deflect.

As far as the guy whose band saw can "hog through that" - well, if you can do that without coolant on a sub $400 machine and get decent blade life, you'rte the man and you should post a vid of your setup.

I certainly can't cut schedule 10 that fast on a HF style 4x6 and get any reasonable accuracy/blade life/etc. I can't push it through my 14" vertical saw that fast either.

Maybe on a 7x12 or bigger with lots of coolant and a 1" wide blade. But that's more than double the cost and double the space of a dry cut saw.


Loud and scary? Buy a face shield and some ear muffs, or ipod.

I really like my dry cut saw.

 

or use another saw

 

Love it!!, anymore jigs or setups people are using to make collectors with a chop saw?

 

Very impressed, the advantage of a band saw is you can just leave it going, but it does take much longer.

 

,heres mine the jig is similar to dutchaccord one,the saw is a makita tct saw and ss blade,its a better built saw than the ordinary chop saw and works really well downside is its noisey

 

bump!!

 

ttt!

 

ttt!!

 

Here's a first-cut 5 cylinder 8" merge collector I made. If you draw it up in CAD first, then flatten the pipe and print it as a template, you can get good results with just an angle grinder.

 

Which CAD program are you using?
