hey what up everyone in the last video I asked you guys whether I should leave
the hub's from our cr250 as is with this brushed finish or go ahead and powder
coat them and of course like 95% you said powder coat so it looks like I'll
be spraying some powder today before powder coating you'll usually want to
sandblast the parts but since these hubs already have a scuff finish they'll be
perfectly fine without any sandblasting so the first step is to give the hubs of
really deep cleaning it is super important not to have any oil or dirt
left on the part before spraying powder so I'll be wiping them down with this
eastwood pre-painting prep it is really similar to an acetone or mineral spirits
product
as I'm sure you know powder-coating adds thickness to a part so anything with a
tolerance such as where the bearing sits in the hub the brake rotor mounting
surface and especially the threads on the rear hub all that is gonna have to
be masked off with some masking tape that can hold up to high heat
as you can see the masking process is quite tedious but it's definitely worth
investing some time into the cleaner the job you do the end result will be so
much better and you won't have to be driving powder off of surfaces where it
shouldn't be on one thing to keep in mind when you mask over a hole you're
gonna want to poke a hole through the masking tape before you run the part
through the oven if you don't poke a hole through the
tape once you run the part through the oven the tape will shrivel up around the
hole and it'll leave some exposed areas so just a little slit will do doesn't
take much so the rear hub is all finished up with masking and the front
hub should be quite a bit easier I'm gonna knock this one out and then move
on to the next step
the masking is now 100% done just gonna give the parts a quick wipe down with
the cleaner before preheating them in the oven at 350 for 10 minutes and what
that will do is burn off any remaining oil and residue one thing to consider
when you're handling the parts is your skin has oil in it so I prefer to wear a
set of gloves whenever I'm working with a part besides during the masking
process
alright I'm gonna work on one hub at a time the front hub is at first before I
toss it in the oven I'm gonna thread a lag bolt into one of the spoke holes
here and what this will do is it'll give me a solid ground so after the first
coat which is going to be Chrome it'll be tough to give it ground and so I'll
use the screw as a grounding point and that should work pretty good for the
second coat now I've got the hub hanging from a hook and it's in a spot where it
doesn't really matter a whole lot I'm just gonna hook it on to the rack here
and toss it in the oven just pull the hub out of the oven and I've got the
powder coating gun set up over here with a chrome powder as soon as the hub cools
down I'm gonna give it another wipe down and then it's game on to start shooting
powder while I'm waiting for the hub to cool off I think I might pop in a pizza
I mean why else would I have an oven in the shop so this is the final wipe down
before spraying powder she is all ready for action and a clip on the ground
right here and get spraying just gonna test the flow of the powder real quick
here make sure there's enough coming out all right looks good
looks like I've got it coated pretty evenly always good to check it over
before putting it in the oven so for you guys I didn't see the last video on
powder coating the shock spring basically how this works is I have a
chrome powder right here this is going to give like a really reflective finish
and it'll serve as the base layer for the color coat that I'm going to put on
top of it and so the color coat that's going on top is going to be a
translucent so it's going to shine through or it's going to show through to
the chrome base and it's going to give that candy or like an anodized look to
it into the oven we go it's gonna bake this one at 450 for 12 minutes
but 12 minutes is up we should have a shiny looking part now look at unreal it
is mind-blowing the capabilities of powder coating I mean this powder looks
almost exactly like Chrome so I'm gonna have to time this perfectly as far as
sprite in the color I don't want it to cool down too much or else the powder
won't stick but also if I spray it too soon the powder will fluidize on the
part and the finish won't turn out very good you guys guess that I am spraying
these parts in the same red that I used on the shock spring
so for this coat I have it in for 10 minutes at 400 I am really anxious to
see how this one turned out damn that looks amazing let's pull it out
so the front hub cannot look and incredible and I'm hoping that I can
nail it on the rear hub as well gonna follow the same exact steps preheat it
wipe it down spray the chrome and then top it off with the red
now I'm gonna peel off all this masking tape and get some tasty shots of Hubbs
all finished up
you
I know you guys enjoyed this video so go destroy that like button so right now
I'm waiting on a bunch of parts for this bike to show up and I'm really hoping to
get these wheels back together soon so keep a lookout for that video alright
have a good one I'll see you later
you
