hi i'm paul brodie we're going to hang out in the shop for a while today i'm going to be a
fabricator and an assembler i talked to mitch he says he's happy just to hang out and work
the cameras so we've got teamwork happening here the last video remember these guys these were the
push rod rod tubes these here are the push rods and you can see how they sort of twist a bit
they because they go from being across the frame this way to in line with the frame up at the head
so these tubes are about 3 16 inch too long or something like that there was a gap
there it's not there anymore because i don't have a tube in there so look i have a drawing i made
a drawing yesterday i have metal this piece is inch and a half od it's 60 61. this is 19
that's what metal costs these days including tax so we're going to go over to the lathe
and we're going to machine up a push rod tube and then i'll take off the cylinder head we'll put the
tube in and hopefully we can we can talk it down and this engine will be basically assembled that
would be great i never i thought it was going to be a two-part series wrong this is part three
thanks for sticking it out and hanging out let's go to the lathe
i have to machine this and it's about six inches long and so what i'm going to use
this is a live center can you see there's a bearing in there this is live center as
opposed to a dead center there is a thing called the dead center it has no bearing
it just is
uh
um
i was using old scotch brite this is new this is a little bit coarser so this is
worn but it makes a nicer finish and even after that you can see little little marks
in the 6060 one i'm not sure why that is i was at metalmo yesterday and they checked
on it and they said hold on because we've been having some problems with 6061 and
i don't know if the grade was soft or something but see all those little marks in there
that's not what it's supposed to look like so anyway
it's supposed to be 900 so it's 901 so we're good what i need to do now is to cut the taper
because on the push rods if you looked at the motor you see how they came
up at an angle like that so you need a lot of a lot of clearance at the top
ah
you see that it's got a taper in the end allows for the push rod room
so when the transition is not bad
i'll live with it okay let's go to the hacksaw
foreign
so that's what it's looking like now this shoulder got made a lot smaller
so let's let's go to the vise i'll hold this really carefully and we'll make a mark here
i'm going to put put my red red sharpie felt pin on there right now see i've got an o-ring that
goes on each end so these have to be squished a little bit so for these two o-rings i've allowed
a 50 000 squish which is a little less than a sixteenth of an inch so i was estimating
i was guessing we'll see how that works out so this that's the size right there
i can machine up to that almost and then i can take it out and i can measure once again but this
is going to give me a pretty good indication of how close i am i was watching youtube last night i
was watching alan milliard he uses a black sharpie we're obviously different people i prefer red
so
now i go from fabricator to assembler
i wanted to show you can you see here can you see hold them up can you see how much longer this
this one is on top it's about it's close to a quarter inch longer
there you go angling up it's a lot longer so
i hope i got this right here's the o-rings that go on it's the whitish one off-white goes on top
and can you see how there's a little shoulder there but i didn't make it too long because i have
to have to look inside and see how the push rods are doing how they're meeting up with the rockers
and then this is the bottom one and i got a little larger shoulder here because it goes
down inside the case so we're gonna take off the cylinder head we're gonna put in the push rod tube
and hope i got a wrench off of peter thank you peter he gave me some other sockets and stuff he's
not using them anymore and it's a 5 16 whitworth and it was ground down on the edge can you see how
can you see how slim that is it fits right in so i spent a little time yesterday and i i polished
it and i took off the lump right there on each side so thank you peter the wrench is getting used
see here how it just fits in there can you can you see that there's there's no
extra room if it wasn't ground it wouldn't fit so very handy wrench for this engine
there we go so here comes off the head
whoa there we go there's the push rods so let's see what happens here
oh
look at that
so anyway i'll tell you what happened i guess i have to put it back in the
lathe and machine it a little bit i didn't want to do that
see i put this in this goes in like that and look look what i did yesterday i go oh it's got quite a
bit of clearance there so i can make this a little bit larger well apparently even though i did that
i guess maybe at the bottom it narrows down because
that does not want to go in there maybe it maybe it's this step well i don't know
anyway we got to do some stuff let's let's check the top here see if the top fits
i thought that might happen see how it's because i got i got the taper there
i think what i might have to do is just take a little bit off the well
it's just a little it needs a few thou taken off
okay mitch we have to go back to the lathe i'm sorry about that
maybe what i need is an arbor
you think i need an arbor make a make up an arbor how long can that take
got a little bit of grease here because aluminum likes to seize onto
a steel shaft so be real shame to put it on there and then not be able to get it out because it gold
well i didn't anticipate this this is
oh well just what happens when you make stuff things don't always work out
that's a good fit
that should be enough to hold it
wow i well no it's going i tapped it on with uh a plastic hammer
okay oh i see it's a little snug
here we go oh look look at that there's a little bit of play there but that fits well on the top
it's not fitting
so
what we need to do is to take a little a little grinder and grind that up i've
got everything masked off i just have to mask off this hole here and then it doesn't matter because
i'll put some masking tape over these too
okay this is assembly now so
see what happens
there we go
it looks like that one's in so let's look at the other one then there's just not a lot of room
you have to kind of guess oh i think that went in
kind of lined up
okay i can see that the gasket is getting a squish on it now so finally
see these rocking that's that's valve overlap so okay
this is the aftermarket rocker feed made by webco in california i believe
acorn nuts we made
something like that
that's a nice snap on i think someone was asking about this it's a a quarter inch drive t-handle
with an extension and then there's an an adapter to go up to 3 8 and it's just i
mean it's got some flex but it's kind of a nice i like it it's a nice little tool so
i like nice stuff
maybe you've noticed
that's our show for today thank you mitch and i like coffees if you buy us some
that'd be much appreciated if you enjoyed the video please give us a thumbs up subscribe i'm
glad this is basically done see you next time thanks for hanging out in the shop take care
