I know a good guy in Thomastown who can do it; he is very good and fairly cheap. I had the factory next door to his when I was set up there.

He makes amusement rides and equipment, use to make bike racks/carriers at one stage and does good fibre glass work as well.
Russell is his name, tell him Larry's mate Jon (crane guy) sent you.
If he can't do it he can steer you in the right direction, he has been in the business of tube bending and powder coating for years and knows his shit, he use to have the big factory in Preston called "Benders" if anyone remembers..
Anyway, to get there go around the Ring Rd towards Greensborough and take Dalton Rd exit, be in the left lane toward Epping as you need to make an immediate left into Spencer St, then left again into Brock st, he is a few factory’s down on the right. Good luck, HTH
