This is a beautiful bike.

I was at Harbor Freight for the first time last month. I saw a rather inexpensive powder coat machine. The more I investigated it appears that a heat source is needed to bake the coat.

What do you use for heating. I would like to powder coat without having to disassemble some of the parts.

Is this possible?

Still curious about what people are using to heat the parts after powder coating them. I have read that a surplus oven is good. Also there are very expensive infrared lights are used.

I would like to get into this area but have no knowledge at all.

Is there a satisfactory way to powder coat parts while they are still assembled on the bike or does this question reflect my lack of knowledge?

Thank you for any help.

there are many advantages and disadvantages to power coat.
one, is after the fact repairs (touch up) is a big PITA. on powder ! ( i have custom PPG in spray cans , ready)

first you need a paint booth ( or you get dust , dust is attracted to HV)
then the parts is charged up to a high voltage , hanging from an insulator.
the paint gun (HV powered) is the other (minus side IIRC) of the HV connection, and the gun is activated and
the powder is attracted t he part, ELECTROstaticly , just like small paper is , when you comb hair
and get said comb brought near to small paper chips. (grade school physics?)

the powder then clings to the parts, the the part is sent to an oven. (UV )
the powder melts, and flows and then you kill heat. or remove parts.
see eastwoods page.

HV is a High voltage power supply, (electrostatic)

dont work on organic fillers ( bondo) limiting and making repairs very expensive
or lead/solder. fillers
dont work on assembled parts. (you want the bolts glued on with paint?)

they say it is stronger, but my PPG top paint are quite strong to and easy to touch up. vastly.

basic 1a, its a craft and all crafts , are skill and practice. which i have neither , im a tech. not painter.

my cl77 was PPG , pitsberg paint , painted by me. easy ,
if i get a stone chip
the chip reveals , heavy zinc primer. so it don't rust and boil the top layer off.
and is painless easy fix.

Electric kitchen ovens (not gas) work well. .............lm

You will need an oven. I found an old electric pizza oven on craigslist for $50.00. Works great.
Yes, when powder coating, you will need to take all apart; especially bearings or seals.
