I am planning to build an oven and use a propane space heater to heat it, I saw in an earlier post pics of an oven using the same method and was wondering if the force of the air disturbed the powder and how to filter the air going in to the heater to stop it blowing crap in. Do you baffle the inlet and what sort of size is the vent in relation to the inlet.
I am in the UK and use two guns, a Hotcoat gun for small pieces and a Mindon industrial gun with a fluidized bed for larger jobs, both do a good job although the Mindon gun is more robust and can feed out the powder a lot quicker.
Your forum has been a great help to me, I am a blacksmith and fabricator and used to wet spray or farm out my work to commercial powder coaters with the coinciding hassles.
Any help would be gratefully recieved.
P.S. I can recommend Rohm and Haas as an excellent source of bulk powders in the UK.
