hi i'm paul brodie we're in my shop again mitch
is behind the camera fabricator filmmaker and there seems to be a lot going on in my shop
so we'll we'll kind of get right into it and i got we'll do what's new what's new is is is foot
peg rubbers for the tiger cub these came from somewhere they came in the mail they're quite nice
they got triumph embossed on them in the rubber and so i was working on the pegs because the
pegs were kind of of bent so you can see here that's where the pegs go like like that and
this one here still doesn't actually this this is the one i'm having having some trouble
with it doesn't want to fit properly it doesn't mesh in there so i'll show you what i did i had
the foot pegs on the frame because when the when the when the foot pegs are mounted on the frame
i can put a ruler right across and then i really know if they're straight i got the big torch on
there and then at the end of each peg i use this wrench so if i take off this peg here i've got
the pegs on the frame and i can i can heat it heat it where it's bent because i can see where it
goes up or down and then when i get that red hot i move it how i want so i got the the pegs
nice and straight and then you can see the heat stains here i heated here here and then this one
there was a lot of heat went into this peg here then after that i bead blasted them and i
saw how how worn they were where they mounted so i did some welding and i i tig welded them and
i filed i'm in the process of filing them all down so that they fit nicely there so it gets a nice
sharp edge and then they'll go into the spray booth on the bike i've got the heavy heavyweight
forks on here so that took a little bit of of work to make them fit properly got the
handlebars the new handlebar clamps this one still isn't quite done and then
i was looking at the bike last night and i was thinking okay it's it's raised up a bit
so i've changed the and the word that came to my mind is the stance of the bike and i was thinking
well i i never knew that word until i started looking at psychic thief that's a website it's
exif maybe it's ixif maybe it's exif i don't know i think it comes out of australia and they got
a lot of custom bikes there and a bunch of years ago they talked about the stance of the bike and
so i always had that in the back of my mind but never really quite understood what they
were talking about so i googled last night i went just i looked up up up stance and and
the dictionary term is a way of thinking about something especially expressed in a publicly
stated opinion so that's what what the dictionary says but that doesn't really let you know about
the stance of a motorcycle so then i i googled stance of a motorcycle and that's to do with
the seating position or the posture of the rider your shoulders should be stacked above your hips
and slightly pushed back so that's the riding position that still doesn't let you know about the
stance of the motorcycle so then i went to bike seat and i looked around and i found a cb550 cafe
racer and they talk in the description it's got a spot on stance so what is what does that mean i
don't really know so i hunted around some more and i found a a motor gutsy that was it was it
was customized in in japan it's a v50 and this the stance is tweaked that's the word they use so i
read down some more and what they did to alter the stance is they lowered the forks 40 millimeters
and they re they lengthened they put longer shocks on by 40 millimeters so what they did basically
was just they moved the whole bike like that they changed the stance now is that a good thing
not necessarily because when you make the fork shorter you lose a bunch of the travel and so
maybe that's a good thing maybe it's not it depends on the fork when you put a longer shark on
the back it raises up the pivot of the swing arm that's what some of the road races do because
they want more more more cornering clearance but it affects the chain it affects a few
things so it's not that's not always a good thing either so then i'm thinking
about this bike and so we actually measured how much longer these forks are over the the
shorter forks 40 millimeters it's exactly the same so it's interesting that this is 40 millimeters
and the bike that i just talked about the motor gutsy also 40 millimeters on both ends when i look
at at bike seat over the years one of the things that really really bugs me is they've got a custom
bike they've done the exhaust the tank the forks they've done everything and then they've got it
in the sunlight it's under the the under the under the tree the lighting's perfect and under the
side stand they got a two by four because they've raised the bike up or put small wheels on or
done something but they didn't fix the size stand so that's one of the things i want to do right
now because the side stand was the right height with those other forks but now now we've
altered the stance made it a bit like a chopper even though these are stock forks on a cub
we're going to check the stand that's next so you can see here that that the bike leans
quite a bit some people would say that's that's fine but i'm going to get
a piece of half inch aluminum and i'm going to put it underneath the
stand and we'll see what happens in my mind i thought half inch might
be the right amount but we'll see let me get another piece of metal so
i got another piece of half inch here so you can kind of tell by how much it goes over
so let's take out that so this would be this is one quarter so this is lengthening
the stand by three quarters of an inch and i kind of like i kind of like that angle
there when you park a bike you're not always parking on a perfectly level sometimes
the ground's a bit uneven or soft so okay so upcoming video we're gonna make the stand
three quarters of an inch longer okay so we're gonna do something else today this is a frame
a bicycle frame this belongs to mitch he built this in frame building 101 and there's a couple
things going on i'm sure he won't mind me showing you he sprayed it with a spray bomb and look
we got a little bit of paint peeling off there that looks like an issue to me and when he
took the frame apart his seat post is stuck so he's put some penetrating oil down there but
apparently that didn't work so this is what we're gonna do now we're gonna leave the tiger cub alone
for a little while and we're going to remove the seat post if we can hopefully we can and then the
frame is going to get be blasted and primed so so that's where i i met mitch i taught 65 frame
building classes over nine and a half years and mitch just got in there i think he was in class
number 63 that's what he tells me so i believe him let's see if we can uh take out the seat
post i got the bottom bracket cups in here so hold it in the vise that's
what we do with bicycle frames and it's pretty don't want to bend the seat really okay so we're
going to apply some heat we're going to i got wd and the post probably goes down to about here
somewhere so we're going to heat up this area here and see what happens i've got a scraper
it's made out of a triangular file and this is going to stop a lot
of smoke going into the shop you can see this this paint comes off pretty easy i think that's a rental seat tube isn't it yes it's on the thin side okay putting a larger tip so it heats up faster going
from a zero tip to a number one it does make a pretty big difference in the
amount of heat that it puts out so what we want to do is to heat
the tube evenly we don't want to hold the torch in one spot that would
not be good so we keep the torch moving and you'll see a little bit of paint start to
smoke in a while there we go a little bit of smoke some of the penetrating oil blowing off okay we'll have a little little look-see mitch you stuck it good you stuck it really good a typical mountain biker not making sure the
seat post is well lubricated it happens a lot i bet if i check my frame i might have a similar
problem that's why i'm not checking so what this does is to heat up the tube a little bit and
hopefully add a little bit of clearance although the aluminum inside is probably going to want
to expand a bit faster some of you might say but heat sometimes helps so we'll see what happens it's pretty tight so oh hot it seems pretty stuck to me what we've done is to take off the seat and we're
going to hold the hold the top of the seat post in the vise this is we're heading to last resort
here that's kind of where we're at because does not seem to want to come out
and this is quite this this whole area is quite warm now from all the
heating we might ruin the seat post but we're trying to save a frame you no sense okay so i wasn't strong enough just holding
the seat that's what was going on so here we're going to put some wd down again and
because this is basically vertical that should what a pleasing noise mitch is happy about this
i feel he's going yeah we're gonna get it out bye there we go more smoke well that's good
that was that was a successful operation mitch was telling me he went online last night
youtube looking up people with stuck seat posts and one guy couldn't get it out so he cut it off
and then he reamed the entire seat post out of the seat tube that's kind of crazy but maybe that's
what you need to do sometimes okay so we're going to get this washed up we're going to do some bee
blasting and then we're going to do some priming we're going to be in the spray
booth today thanks for stopping by i thought i would tell you a few things about
spray painting a bicycle frame so first of all you need to do some masking on the frame and so what i
have here this is the mask for the seat tube it's a it's a piece of aluminum it's got a little
bit of a taper here so that when you put it in it stops right right about there because it's
it's on the taper and then you need to mask off the water bottle bosses so i have a whole whole
container of just allen screws and you can see it's got paint on it so that's what keeps the
paint from going down into the thread you don't want that and then you also have to mask off the
bottom bracket because you don't want any paint going into the thread so i made up a system here
it's aluminum it got turned in the lathe there's a a piece of eighth inch flat bar a wingnut so i put
this in from this side here it goes in on the left and i'll show you why why i have this okay so the frame is going to hang on the rack
like that and then when i'm i'm painting it goes on the hook so you see here i've got two
hand holds and i can hang it on the hook here the head tube and then i can
take it off the head tube and see this hole here i can hang it upside down
because you need to be you need to have access underneath if you only have the frame
one way i've seen i've seen people paint bicycle frames like this and they spray it
and then on the bottom they always miss because they can't see what they're doing underneath
so that's why this system works pretty well so the spray gun i use it's a graco it's a a
detail gun it's used for the inside of car doors when i learned to paint i
was working at rocky mountain they needed a painter so they they asked me to
paint and i said well i don't know how to paint and they say well we don't know anybody else
so i went out and i taught myself how to paint when you when you're spraying you want the
gun to be maybe so far away this is the fan this is what opens up the spray like that
all fine when i spray paint a bicycle frame because the tubes usually quite small i don't
have the fan open much at all maybe just a little bit but mostly it's closed so it's a quite quite
narrow and then and then this one this knob here it controls how much paint is coming out so when
you're when you're getting ready to paint it's a good idea to have a tube off to the side that you
can practice on to get this more or less right it's not easy spray painting a bicycle frame i'm
told it's a lot easier to learn how to spray paint a car because what happens is when you spray
you have to start and stop and you want to stop at exactly the right spot you don't want to go
up up here up farther or overlap because when you spray this tube here you want to go to the corner
so that it meets if you're going over a bit and over a bit you're going to get a run or a heavy
spot it's really crucial that you get the right amount of paint and that you're really accurate
and you and you don't go over the same spot more than what you want to do so anyway we're
going to go into the spray booth there's a lot to know about spray painting it took me quite
a while to learn how to be a good painter and even now i don't think i'm a great painter i i
tell people that i'm a fabricator masquerading as a painter but anyway we're going to go into
the booth mitch has his camera and he's gonna film me spray painting we're gonna prime
his frame today that's the goal so let's go so so so well that's our episode for today i hope you
liked watching mitch's frame get painted next episode it's going to be blue with a nice imran
clear coat on it mitch and i like coffee if you were to buy us a few coffees that would be perfect
thank you very much we'll see you next week bye
