numpty trainee question - again !!

[jurgen500]

OK, here is the question. As part of my upcoming assessment I have to do a full passover (without using fittings - bending only) on 15mm pipe such that the passover is 30mm "deep".


Should I start with a 45 bend and then bend each "leg" back or is there a simpler way ? I always seem to get a bigger passover as I cant get the damn pipe in the bender close enough to bend the "legs" cos the pipe retainer is in the way

thanks again !!

Practice is what it takes, lots of it.

I always bend the center first and then the two legs as you say.

Another way to practice is by drawing it on a piece of cardboard.

you want two parrellel lines with a 30mm gap, mark an 45 angle each side and to a point in the center, round the sharp corners off free hand and you should be able to use it as a template.

Try the above Jurgen. The table of measurements truly works all my pups get this.

As doitall says its down to practice.

get a length of hep2o ..

Seriously, if you reduce your first bend to say 30 degree's you should be able to get closer on the other 2 bend's and reduce the size of the passover.

Like above, lot's of practice. Once you've left college you'll relalise what a load of ****e it all is anyway!

many thanks folks. I appreciate the advice and links.

Pretty much sums up these NVQ crap if you ask me

If you worked for me then I would not want you to waste time bending your own when they cost about £2 for a neat factory made item.

Of course the college has got to teach you and I dont have any problem with that.

The best students have their own tools and buy lots of 15 mm tube to practice on.

Nowt as nice a looking as well formed pipework, with as few joints as poss though is there Tony

I agree no other way really

When I was an aprentice (when Pitt was in number ten and you could buy a house for a shilling and a potato) I used to pick a bit of wall with an internal and external corner and 12 foot of copper and try to get my sets bang on.

Never did succeed so I threw me handy benders away and brought rather a lot of end feed elbows

As somebody on a forum said, elbows are neater than bends!

There is an advantage with gas pipe though as a pulled bend has less resistance and you dont seem to be able to get slow bends any more.

thats true


and I must admit that when I am running a new gas line I always use me benders, very forgiving are pulled bends

I would like to see you do that with a six meter length in an A frame.
