on this setup I have a little bit of
problems because of the draft angle on
this base here on the top I don't want a
machine that top but I've machined the
bottom and so I want to hold it as a
reference as the base so I could work on
this end and what I did is I used my
nice machine jacks from the boys up in
Canada these are really nice and they
supplied a top piece to it with a divot
in it and a V group but a divot is for a
bail bearing that's why I have a ball
bearing in there and I was able to
adjust them differently to press against
here so I have even pressure holding it
tight against there then would be
clamped of course with the jaw of
the Vise but since they're not even
surfaces I was able to adjust these so I
could clamp pretty evenly and keep it
square then I used a dial indicator to
dial in the angle here so it's flat and
that works then I then used an edge
finder for the back edge a reference and
this side is the reference side so I
went with that and down and then the
reference side from here so we're in our
location for the first hole and I'm
going to drill these holes and
tap this a quarter twenty eighth and
then I'm going to make my own little
fittings that will screw in there
I have to drill one and 3/8 down or down
to bend down in there has to go far
enough for the port on the other side of
the shaft now I'm just going to I'm just
going to  tap it a little ways down there
now for the counterbore on this face and
it's 0.700 in diameter and 1/8"
inch deep and that's clearance
the screw head clearance I should say
for the mounting of the cylinder
that's boring head back in and
I didn't change my setting so I should
put a 0.7 circle hole in there a little
burr that's on there while we're on this
side
Oh a little a little heavy but that's
alright
there's gonna be a thin plastic or
Teflon washer it sits against here now
I'm going to do a spot drill with a
small Center drill just like I did
before with the port where the ports go
now these ports will be 30 degrees this
way and that way
I turned it I put it up on a 30-degree
angle block down here and lightly
clamped it it's pretty solid but it's
lightly clamped it's not anyway I just
put my scraper in there as a pointer
it's dead center on there bottom mark
here we're going to do it just like I did
before with the end Mills
we should be all finished with this bass
I'll take it over I'll clean all this
off all the Dykem we can take a look
at it let's take a little look at this
this this base is done I think it came
out pretty good pretty happy with it you
can see there now I mean you know I said
I adjusted the where these bores are
and then I had to just a couple little
other things on the engine so they could
be pretty much in the center of these
bosses and I measured on this side this
one it looks really good
this one's maybe a little on the lower
side of it not much and this side is
pretty good it's a little off to this
side here
and then of course this side was a flat
surface so it didn't really have
anything to line up on but the porting
came out really good there right came
out perfect into the port's here which
extend all the way down through here so
those those all came out just right and
I think their placement looks really
good i I didn't double-check them yet
but they look really good so I'm really
happy with how this all this little bass
came out so far yeah and when we're
going to get on to the next one the next
base and get it done so thank you guys
thanks for watching please subscribe it
really helps and we'll have more more
model making content going
there's the piston oh here's the piston
yeah this piston will be on here and
it's going to work like that
alrighty guys let's go
