A few observations when tackling this job. ALWAYStakethe frame apart completely, do whatever rectification needed to straighten or weld, then have it powder coated. Then it can be re-assembled, having cleared the threads with the appropriate thread taps. It is most unwise to do it `the easy way' & have it coated `in one piece'.
Apart from getting poor coverage due to overlapping construction you will almost certainly have operating problems!
For those of you un-familiar with this process may I explain. Paint in powder form is sprayed onto the metalwork @ very low pressure under a negative charge. This attracts the powder to the metal. The item then goes through an oven @ around 200oC, whereby the powder gives in & is fused to the metal. That is why it is so hard-wearing. Unfortunately, the powder doesn't differentiate between the main metalwork & the poor little shims that are on every joint which are supposed to revolve,some as thin as 1/32in. They just bake together & need a hammer & chisel to separate! Believe me! Also, under the extreme heat, any rust particles on the bolts will proliferate, (rusting is heating), they will no longer allow parts to swivel on them. Instead,quite often,they force the movement of the joint through the securing thread, either stripping it or shearing the bolt!
If the bolt heads & nuts are all nicely powder coated then the frame will have been coated in one piece! I hope this is of value to anyone about to tackle this job.
