Re: Post pictures of your collector jigs.
I've got a jig for some 90 degree Els for a collector, its a little messy but its just the same rotated via 90 degrees. I've just took a big order on making some that require cut 90's, so i'l make a better jig and post pics.

Re: Post pictures of your collector jigs.
I wasn't trying to be dickish...don't get me wrong. I was just saying, that it appeared to just be a clamping system, not a true jig. Jigs should be something that can accurately reproduce a unit while eliminating, as much as possible, user error.
Using a dial indicator and levels is certainly going to result in the finished product, but that's not truly what you want out of a jig. IMO a jig not only accurately allows you to achieve the end result, but to do it in a speedy and fairly easy fashion.
My first jig used a similar setup, and don't get me wrong....it cut very well. The same issue existed though. I had to turn it, use a reference level between the blade and the first cut, etc. It worked well, but it still was pretty time consuming. I didn't care much in the beginning, but slowly, creating collectors became a pain. That's when I set out to make a jig that was simple. Put the piece in, hit the power button, unbolt it, turn, bolt it again, hit the power. The endplate that was perfect square was all the difference in the world....aside from saw setup.
To each his own though...if you like how yours works, then your good to go.

Re: Post pictures of your collector jigs.
i don't use a jig to cut my collectors and the come out reasonably ok. i do them a bit different than most people though. i don't make all the cuts and then tack together. i make a cut, tack, make another cut and then the final cut.

Re: Post pictures of your collector jigs.
Has anyone figured out a jig to cut bent tube? We spent some time on this a year back or so for cutting some 18 degree bends into 4-1 collectors for a production job.. and the result was less then desireable. We ended up using off the shelf formed collectors instead.
If you've got one or have design for one - we pay top dollar for R&D.

I can't find any good pics but here a few anyways
I've got some 5cyl collectors to make at the end of the week, I'll see if I can get someone to take some pics of a straight shot of the inside.

Re: Post pictures of your collector jigs.
I have not done very many, but I do them on a mill as well. I try to design the collector for the application, not just using premade 4", 5" etc. sizes. Here is some pics of one for a tial v-band housing, the fitment was perfect on the collector end and was welded inside and out:

Re: Post pictures of your collector jigs.
fixture for the first cut, cuts 4 @ a time, no pics of the second cut fixture...
A fixture is worthless if you dont' know how to use it, your best figuring out what works for you, your saw, etc and building it.

Re: Post pictures of your collector jigs.
best way to figure out what works is by combining good ideas found in each persons design. That is why the pictures are helpful. So when I'm sitting here thinking of a way to make a Jig I say, ohh this guy had a good idea for holding it at such an angle, and that other guy had a good idea for rotation of the piece, etc etc.
I still don't get why people are so up tight about their methods.
To all that have helped, thank you for sharing. It is helpful to the entire community.

Hey nice saw Jesse! Whats the throat on that?
I had a local company cut me a 22" x 7" x 2.5" peice of durabar out of a 18" diameter crop they had. I like big saws!

Re: Post pictures of your collector jigs.
Here are some damn pics, LoL. Thanks Focus.
I dont have mine bolted directly to the saw. I opted it that way and hold it in place with my clamps, which allows it to move quickly in a out to change cutting angle/depth. I did not want it in a somewhat permanent place being bolted on.
WORKED GREAT TODAY!
