Cutting 9" Wavin sewer pipe into 500mm lengths

Calahonda52

Oksay, I need then square at both ends and I am not the best with a handsaw.

Plan B is to cut them oversize and bring them next week to the local engineering shop.
I need 6 lengths

Whats your Plan A?

Ak84

Get A4 sheet of paper and wrap around pipe making sure the ends line up.
Mark it up.
This would be a true square cut.
Maybe make a simple mitre box either.

Use a chop saw...

What you up to ?? :rolleyes:
Keeping them still is the challenge, have you a bench vice or similar ?
Sheets of paper goo idea, will need A3 though or newspaper.
I would have thought a good sharp handsaw would do the trick.

Wrap pipe with galvoband, tighten up, measure and tap band into place if needed.
(personally I'd use a slightly thicker, but flexible, strip of metal and make a big hose-clip)

Run saw blade into pipe against the edge of band. Cut a couple of mil into the pipe all the way around but not through into the pipe. Then follow that line. Should be fine.

How perfect do they need to be.
Your local agri supply place that sells steel might cut it on the band saw.
I would use the paper trick and a min grinder.

Thanks guys

Putting up a poly tunnel and want to set out the pipes on the grid so as I can then set the 1 meter uprights pretty accurately.
The tops of the wavin will be level so as to act as markers for the crushed stone base which will go in after the uprights are set
look at the timber frame in the large tunnel options here:
https://dplant.ie/polytunnel-prices/
The timber frame will sit on the top of the pipes so they need to be level as that is how the plastic is stretched

I did try the small angle cordless angle grinder which worked well so that will be the cutting.

PS
I down graded to 6" when I went looking, buying off cuts at 6 euro/m, the 9" is 30 euro/m:(

Buy 1m lengths and cut them in half, the uncut end will be level, that's all that would seem to matter based on your usage.

Fine Cheers

Interesting project.
So are you placing the uprights into the 6" pipes and back-filling with gravel / concrete ?
Is the 1m below the ground ?

I reckon Ak84s idea of a simple mitre box made to the size of the pipe and about 20 mill higher for setting the saw is your best bet. A half decent handsaw would fly through pipe

Balls to that , this needs hot wire or maybe even lasers. You are thinking too small

while I'm all for over complicating solutions to problems for any excuse to use any one of the arsenal of cutting tools I have to hand in the van. Sometimes the humble hand saw is still the quickest and easiest way out of a problem.

MayoForSam

Measure whatever length you need from a square end, mark a few points around the circumference and join them up using some cardboard as a guide. Then use a handsaw to make the cuts, perfectly adequate for the job you describe. You're not making the next SpaceX prototype.

As mentioned handsaw (I prefer a hacksaw for a finer cut) around the perimeter without cutting through will give a square cut.

Shocked with above prices however, I guess 9" is industrial and not that common but a 6m length is €93 in Goodwins so expensive tack alright, 6" length at €46:

It was mentioned earlier to buy 1m lenths and cut in half, didn't think it was possible to buy pipe (sewer, ducting or waste) by the meter or do some providers sell it at an increased per metre price.

Thanks guys, I have one fixed will post a picture later, as its the reference point for all the rest for levels, I have a new approach.
I hadn't thought the project through...
.
cut them a little over length once I have the hole dug and set then with post fix.
Then mark the correct level and mark it and cut with the angle grinder, that way the hole depths can be whatever and I just have to focus on the get the wavin perpendicular in the X and Y, and not worry about keeping it level as well.
.
Thanks again

All learning.

Paper and grinder.

Shop says no, it wont set, find it hard to believe, any thoughts?

I'd imagine it's a stock answer given to customers so when a project goes wrong, the customer can't come back and say the fella in the shop told him he could do it
