Has anyone done this ?.

I have a 22mm bending spring intended for 22mm copper
and it is a fairly loose fit.

I was going to heat the pipe with my hot air gun
and bend it around something round or maybe
hammer some nails into a bit of old plywood and
use them as a 90 degree guide.

I am replacing the gas pipe that was used to run
power from house to garage in 1976 with the correct
stuff, so needs a 90 degree bend at each end to fit
a metre wide path, before re-instating the path
(dug up for other reasons).

Why aren't you using SWA cable?
Is this round or rectangular conduit? Round can be bent after heating
with hot water but will start collapsing if the bend is too tight and (I
suspect) may trip the spring. Why not use the joints made for the
purpose (or SWA)?
You can get a swept bend for the conduit which is easier to push cable through than the normal bends. I pushed 10mm2 T & E through when providing power to my garage. The only thing you may find is that the likes of Screwfix et al only stock the two types of inspection bends. I got mine from CEF.
