Default Conduit bending

I have some full length 3/4" conduit that I need to make some bends in. The problem is that I don't want to spend forty or fifty dollars for a bender that will only be used once. My questions is:
Does any one have a suggestion as to a way to make accurate 30 or 40 degree bends without collapsing the pipes? I'm open to suggestions.

Thanks,
George

Have you looked into renting a bender?

Call a local electrican see if you drive by the shop if he would bend it,he should be able to bend in about 15 to 20 minutes. If they will not do it they may be able tell you who will

You're a stranger George. I don't know if you're referring to plastic or metal conduit. For plastic I use a bending spring and gentle use of a gas flame. I haven't bent metal tubing for years but when I did I used a length of 2" x 4" and drilled a hole larger than the diameter of the tube and gently put downward pressure on the tube as it was slowly pushed through the hole. The results were a nice clean gentle bend. My three bending springs can be seen in the first shot whilst the second shot shows conduit that I bent when wiring my shed 10+ years ago.

Thanks for the replies. It is rigid metal conduit, Harry and I like the hole in the board trick. I think I will give that one a try. Now all I have to do is try to get eight identical bends.
In case you are wondering I am attempting to build a hanging basket stand. The one Shirley was looking at cost $100 and I can't see paying that kind of money for four pipes screwed together.

I'm sure that Shirley would prefer you to make one out of WOOD George! If however you proceed with conduit, I forgot to mention, rout a roundover on both ends of the hole.

Fill it full with sand before applying any heat.

Bending with fine sand is the cheapest and best solution. See:

Fine sand and as BCK mentioned above in the first reply - use C Clamps and something round to bend it on such as a bicycle rim, vehicle rim, wine barrel, concrete pillar or metal pipe, depending on the curvature required.
