old timey bending block

[sibbits]

any one know how to make/use an old school wooden conduit bending plank?

They use these across the pond.

there was a guy on Utube doing American conduit forming using his knee to bend the pipe , did a pretty decent job of it

I also use one of the above sometimes.

Do they work for our 20mm? Been thinking of one of them in lieu of a bender

US conduit is thinner than UK - they have a wall thickness circ 1-1.2mm uk class 4 is 1.5mm

3/4" US conduit is approx 25mm UK conduit in diameter I think

Ooo may have to get me any UK suppliers?

Don't know, lots of similar for water pipe.

I would look at getting a proper one if I were you, you will need one or something similar to hold the vice for threading the conduit in any case if you are using it in anger.

There are some cheap hilmor copies around, or a second hand copy in the order £40-£80 on various sites.

UK suppliers?

Got mine on Ebay, I do have a hilmor one of the old types got it for £30 and painted it.
