I got the same tight bends you have.

I am going to experiment with heating and bending. This will need to
be done outside due to the release of dioxins when PVC is heated
significantly.

I bought all my 6" S&D fitting from the local Locke Supply. The only 1/4 bends
(90 deg.) available from them were very tight - almost square corners - and
unusable for DC ducting. I wound up using two 1/8 bends (45 deg) and a short
length of pipe to make my 90's. If you found sweeps or large radius 1/4 bends,
you might post the name/location/url of the supplier.
