hi Tracy hi Adam um apparently you've got a wheel problem I have a real
problem I have a crazy Bengal cat that loves to run on this thing at night
what's his name his name is Ziggy and he's like he's big he's big he's like 18
pounds oh and this is losing weight he's losing weight because of his exercise
yeah I think his exercise feels a little flawed not moving quite smoothly enough
ah okay this is incredible this is beautiful but I hear a lot of resistance
and it seems a bit wobbly yeah it's not I think one of the kids got on it and
been the--of bearings or something happened I mean it definitely worked
better in the beginning okay needs a little repair job all right
III have some materials I think we might be able to apply to this um let's uh
let's take a look at its components and see what we can see what we can repair
all right oh that's about as simple as it gets
so let's just pop out of here I think that's that's crazy that amount of noise
um oh wow they're glued in let me get a screwdriver this is this is the big one
this um that amount of slop that it has that's noise and if that's wobbling
while the thing is wobbling it's introducing friction that's not
perfectly linear so in preparation I bought this which is a hard skateboard
wheel and a thicker axle so here watch this pick up that and spin it right so
they didn't even see the wobble on it yeah so go ahead and spin that one oh
yeah absolutely right and this one will spin for like 15
seconds right that one stops almost immediately and times 9 it's a lot of
extra like vibrational rise so there's that now this is let the thicker than
the slot so I think I can machine this down on my lathe I'll need to
machine it so I need a machine these three in the meantime I can have you
start pressing bearings into these wheels okay cool I'm going to put
bearing on top of the wheel like that and that's it nice and level in both
sides of the wheel okay
the problem with making the holes bigger is that this has been precisely machined
and and it's put together together so everybody went in anyway that's yeah
yeah precise enough but I think I'm a little bit I think I've gone a little
bit too tight with my tolerances I'm going to make two more of these and it's
going to make it a lot stronger than this I mean I can bend this axle with my
hand set and this one is significantly stronger right so this is just going to
take me a couple minutes
see what they've got here is they've actually machined a little notch into
the axle which is ridiculous because it makes it even weaker right and then
they've put a little circlip on there so instead of doing that because that'll
take a huge amount of time I'm just going to use a little brass spacer okay
that threads over and so what we need are two four six pieces of brass cut to
exactly that thickness that width okay right there and I've got this little saw
with a clamp alright then do that and cut it to that we need six of those all
right Adam nine of these one two oh whoops
what we need is actually one two three four five six little I mean little ones
that looks exactly right so we can repair the end you want to give that um
first of all we with a little pair of pliers we'll take off that little bit of
flash and then and countersink bit in it that'll help clean it up all right
so I think those are I think these are ready to go um let's see so it's a so
nice oh go ahead and when you start assembling one an awesome one if
everything goes correctly that'd be it if everything goes
correctly oh I love how like precisely everything fits on stuff okay what do
they get wrong right off the bat over there everything
screwed up really no no it's alright it's just that these wheels I forgot
these wheels are thicker by a fair bit which means all of these are the wrong
length so let's say 0.9 all right again let's try again it looks oh that looks
great okay so there it is okay so ladies and
gentlemen boy fect added me gonna put more hot glue in on top of that or is it
really necessary we could put it actually I'd probably put in a little
epoxy mm-hmm I've got some ready
that a new sound it is how much maybe filling oh yeah um wait a second
let's get away smoother go yeah significantly better mm-hmm
all right last thing I'm going to do I'm going to throw some oil so the basic
gist of it was that their axle was thin I can barely make it bendy which means
that it's going to move these wheels actually can turn on the axle there's a
huge I mean that's like 10 right out of play and then I can feel that these
wheels are also poorly molded like you know that's that's a separation line
right and none of that's good so I went with skateboard bearings with high
quality skateboard wheels I went with very hard wheels rather than soft wheels
that's to lower the rolling resistance after the wheel the more contact there
is any more friction and then finally rather than opening up these holes I
went with some hardened steel shaft which I machined down to fit the
original diameter these but these are super strong and they're not going
anywhere right no I wouldn't say it out loud well
one of the kids could probably get on this record it and I guess you'll take
the spider back home again yeah I think so I think he's good I think he wants to
stay all right there we go cool oh it's much better wow that's gonna be a much
faster wheel that's his radical improvement isn't that insane oh that's
so cool I did I really didn't know if that would be such a good improvement
look at that but he's gonna love that now he's gonna get fat again
really not nearly as much effort oh I see but yeah who's gonna be rang yep Wow
so let me see how long it spins for
all right I mean I think it's freewheeling like
five more rotations yeah awesome phenomenal yeah it's I really can't
believe they had all of this crazy like ratalie wheels in here it's such a shame
cuz it's a beautiful design and I thought this thing ain't no longer even
wanders the way I am it doesn't it's not even warbling at all there we go
thank you sir anytime sweetie anytime at all be happy
to help all right let's get it up to your car all right
