Cutting 6" pipe with 6x4 bandsaw

[anto44]

Not sure if this is the right section.

Need to cut a bit of 6" pipe with my warco bandsaw and this is far as it will go before the blade guide wheels hit the pipe.

I reckon if i can get the front blade back a few mm more it'll go most of the way through till the bow hits the pipe

This bit might not impress a lot of people
Grinder time

quarter turn the pipe then turn it and cut again and get it finished

Why didn't you just cut as far as you can then rotate the pipe in the vice, that's how I do it

 

[Bill Edwards]

I too would have just turned the pipe!

Glad its not just me, i wondered what i was missing. Just cut and turn.

 

[anto44]

I want to get as far through in one go as i can before i turn it and get the last bit in one go. I find the more turns you give it the more out you can be by the time you get all the way around it. I've a good few of these to do and want to make it as easy as possible

 

[Paul.]

In that case remove the rear vice jaw and clamp it on a bit further back, or make a new one from a piece of thinner angle with the hole drilled closer to the upright part of the jaw to give you a bit more room,

 

[brightspark]

right hand jaw may turn round backwards without catching the guide and then pack a piece in the left hand jaw to move job further back

Only needed to grind a small bit off to get it to go past.

 

[brightspark]

but u still need to turn it to finish the cut as its catching on the frame

 

[anto44]

Only need to turn it once now though so should save me a bit of time. Going to have to up grade to a bigger saw though if this becomes a more regular job

 

[Bill Edwards]

What's it for, out of curiosity?

 

[anto44]

It's to make an insert for an exhaust. It fits into the tailpipe to reduce the diameter so its quiter and can be removed if you want to make some noise.

 

[Bill Edwards]

A 6" exhaust pipe!
What sort of monster thing is that from (don't tell me it's a messed up saxo/clio/fiesta )

 

[brightspark]

its a go fast megaphone to make it sound louder

 

[anto44]

The tailpipe is about 5&1/4" the reducer will make it 3". It's on a 2.0l turbo 4wd

I think personally you would of been better off getting the saw to cut true rather than butchering it with a grinder which still hasn't helped as your still going to have to do a 180 on the job. If time is spent fettling the saw to cut true you can rotate the job as many times as you like with little or no effect on the cut quality.

Whats wrong with a cardboard wrap and thin disc in a grinder? Orrrrrrrrrrrrrrrrrrrrrrrrrrr Put a decent lump of plate in the vice that will come through to this side of the saw and clamp/strap/chock the tube to that, it will miss everything.

The saw does cut fair true in fairness to it. I've spent a lot of time fettling it to get it as good as I can. The piece I ground off was a mistake in the casting as far as I can see, it was a raised casting mark that was stopping the guide from retracting fully. The casting mark in the same spot on the rear guide is not raised and it can retract until it sits flat against so i ground off the casting mark so the front one can retract fully.
I've just always found with pieces like this the more of it you can cut in one go the better the cut.

Bob[/QUOTE]a couple of pieces of angle welded to the plate will hold it in place and clamp it down have done similar with mine clamping short stock in that wasn't long enough to fit in vice and overhang suficient
