hey everyone my name is Matt welcome to my backyard and welcome back to the
series I'm doing I'm building this big bandsaw mill! It's been a while! If this
is your first time here, there will be a link up in the cards and down the description to
all the videos that I'll bring you up to where we are right now and speaking of
it's been a while in the last video it took apart
basically the entire saw head so I can get the guards off and get to the beam
so I get everything painted and I started reassembling things. That video took
place last August it is now the following June. The mill has been sitting
under the tarp that a whole time as I've been putting off finishing up the work
on this thing so in this video we're going to kind of keep going with the
theme of putting things back together and I'm also going to start working on
some things that I kind of glossed over and simplified and skipped as I was
building the mill because I was really more interested in getting this thing
operational so getting all the logs cut and out of my driveway then making everything as
perfect or as properly done as I had in my mind. So let's jump into it! So one of
the first things I want to take care of is adding the stops for the carriage so
right now there's nothing that stops the carraige from rolling off the end of the
track and what I typically do is grab a c-clamp. It clamps of the rail and that
acts as a functional stop that prevents the carriage from going past that point
but of course that needs to be a little more not temporarily permanent so I'll make
some little stops to go on to the end of the track and have this piece of two by
two quarter wall angle this is an off cut from when I made my outdoor
fireplace. So that's been sitting around for like four years already
that'll be perfect for a little stop. I can cut a few pieces about four inches
long drill some mounting holes in there and then mount them to the end of the
rails. Now the reality is you only really need
for one side because if one side hasn't stops the other side isn't going to go
past it anyway I'm gonna go ahead and make for one for each corner just in
case might give you some more options for some more things in the future I
don't know what but at least they'll be tenant they're all the way and if I need
to remove them because they're in the way how I saw the ones on the other side
it's like changing I want to take care of these now because they have a few
other things that need to get painted so if I get this things made I can kind of
put those in with the batch of stuff that's gonna get painted they kind of
consolidate things that hopefully save a little bit of time and effort
so here is the first batch of painted parts are we putting on the mill so I
have these stops which I just made I also have the lower thrust bearing
supports for the lift mechanism and the bearing caps the motor electrical box
and this little just there post that holds the adjustment arm for the blade
guides so I'm gonna start by installing a little stops here so I can finally
remove my temporary / permanent stop which is the C clamp it's been out here
for like 18 months and install the actual stop onto the track here so now
there is a permanent stop here so as the carriage comes down the track the
upright will contact this stop and I won't be able to go past the end of the
track thereby you know falling off of the whole track now this doesn't really
get used that often this is more like an emergency stops so no real reason to put
any kind of padding on here anything really should be contacting this during
normal operation as you're coming back and forth on the mill and last something
gets away from you and this is more like an emergency stop so something bad
doesn't end up happening so the next thing they go back on is this adjustment
support post this is gonna get bolted on to the beam and that's actually gonna
hold the adjustment post down here which operates the blade guide on the idle
side so this used to be welded to the beam the life of this whole thing apart
I did disconnect this thing and I did drill holes through it before I actually
cut it free that way things will stay aligned after the hole bolting on
process so I have some pilot holes in the beam already so I'll have to do now
is just enlarge them to the right size and tap them for the bolts
so we need to start working on getting the lift mechanism back installed and
that's gonna start off with installing these bearing plates on the bottom of
those little platforms down there where that kind of temporary support is right
now but it's gonna be kind of hard to actually tap and drill the holes with
the guards there so I wanted to remove the guards but before I remove the
guards I want to replace these little latches
that I installed last time and as you can see they do not hold up very well to
the forces that I need to be there to keep these doors onto the actual guard
assembly so I want to replace these with something a little more durable so I got
these all-weather kind of rubber draw straps which should be able to provide a
lot more clamping force to the guard doors keep those things in place and
yeah I'm not too worried about the hooks he's only like a couple bucks maybe a
dollar to a piece he's a little more than me like seven dollars a piece but
should provide a much better result than what I have right now
so these straps are a lot better than those latches I had on there previously
so I'm pretty happy about that so next I want to start working towards getting
this whole lift mechanism back in there and to make the whole process easier I'm
going to strip off all of the guards and while I'm taking things off of here I'm
gonna pull off these PV and can't talk holders that way I have those things
kind of in the pile for the things they're gonna get painted for the next
round of things they're gonna be painted
whatever that I remember
so now I'm ready estar working towards getting the whole lift mechanism
reinstalled which starts off by installing these bearing holders at the
bottom there onto those platforms were those posts that are currently
supporting the beam are sitting so before I can get to install these
bearing holder plate support things whatever you want to call these things
thrust bearing support plates something like that I have to remove the temporary
posts so I have to find a different way to support this beam temporarily
it's before I move these last year I did Center punch the hole locations so I can
get this thing back into exactly the same position to make sure those lifting
rods are aligned so now I have to do just find the punch holes from like
months and months ago and then drill and tap those holes so this side looks like
he's only gonna get two bolts because this adjuster post support is in the
ways I can't drill back to the mounting holes back here cuz that's in the way
but it doesn't really matter because these bolts is kind of keep the bearing
plate kind of in place once there is weight on top of it from the saw head
sitting on it it doesn't go anywhere I just have to resist any kind of torque
or anything because the bearings take care of that it's really just getting
bolted here so that kind of as you're putting this thing together this play
doesn't kind of walk around on you
and while I'm over here also reattached the nut retainers which hold the Acme
nuts which are part of the lift system
and keeps looking like it's gonna rain again today
it was raining this morning and then it's been raining on and off all
afternoon but I kind of want to get started on this and of course it's a
plane flying overhead now but anyway so this morning I took the step shafts and
the ackee rods and got the keyways cut into them so a big THANK YOU to Carson
for helping me out with that he used his mill to cut all those key
ways for me so we cut the key ways in both ends of the Acme rod to made up
with those couplers don't to worry about those set screws trying to grab and slip
anymore and they also replaced the key ways that I had ground with an angle
grinder into the step shaft so I have actual proper fitting key ways in those
as well so again big Thank You Carson I really appreciate you having me out to
the shop so I have all the parts I need now I can start reassembling the lift
system so first thing I go in are the bearings sit into the bearing holders
there and then I have this cover that I made which would go on top of there and
hope to protect the bearings and keep them free of sawdust now one thing that
I was planning on doing which it's not gonna work out anymore is I did pick up
some bellows for the Acme rods to keep them clean but the inner diameter on
these guys are too small to fit around the couplers apparently so I have to
order some new ones and I don't really feel like waiting for new ones to come
in to keep going with this so I'll have to take this apart and redo that at some
point but that's alright I'll just have to wash these things a little bit better
because the bellows is going to help to keep everything super clean
so to keep sadhus and stuff out of the bearings let's go we'll ring here which
will slide on to the step shaft and now help kind of seal things up against that
cover hey can you slip down there like that and that should help to keep a
little bit more on the clean side
so now I can move on to the top section of the lifting columns and one of the
things I need to do here is actually cut these shafts down to their final lengths
when I originally installed these I just left them long just in case I want to do
something above the carriage system but now that I have the designs finalized
I know that I can trim them down to their actual final length which is to be
flush or roughly flush with the top of the carriage just enough material to
pass through the bearing at the very top of the carriage
and another thing I'm going to do is weld a nut to the top side of the drive
side lift I previously only have one of these on one side but having a nut you
can grab with a wrench or with a socket on both sides will make aligning the
beam a lot easier because you'll be able to operate both sides independently
before linking it with the chain
so here is the driven side the lift mechanism so it has the two sprockets
one that links it to the other side and the one that links it to the motor which
actually does all of the driving force to actually lift the saw head up and
down and one thing I'm going to do over here is push out the size of the drive
sprocket so on the motor right now I have a 13-2 sprocket and then I used to
have this 33 tooth sprocket on here which gave me way more reduction that
actually needed the motor technically has enough torque to drive it out of one
to one so I'm going to swap these 33 tooth sprocket for a 22 to Brock it
which will speed up the travel the lift mechanism and still give the motor a bit
of a mechanical advantage so there's not the work nearly as hard so I take care
of the lift mechanism and I think the last thing I want to take care of in
this video has to do with the base I want to take care of that now before I
start adding weight to the saw head so the issue with the base is two things is
I'm gonna take care of and solve here so first off the saw itself is too close to
my shed that's just happened to be how this whole setup works because when I
built this mill this was all logs right here so I didn't have anywhere to go
except right here it's too close to the shed right now so if I had the saw head
back to where I am right now I can only raise the head about I think
three feet before contacts the fascia board on this shed there which is
something that I totally forgot about one time I had the saw had parked
underneath there I start lifting the saw head up and saw had contacted the fascia
on the shed and luckily I had noticed six I hear all the cracking creaking
there's an airplane flying overhead again but I ran over there and turn it
off quick but that something's been on my mind for a long time so I want to
reposition the saw a little bit is gonna get me a better approach angle to coming
down the driveway I'll be a little more in line with the trailer as it comes
down the driveway the other thing is my idea on these leveling feet
was kind of flawed I guess to begin with so I used to have the bolts up on these
little stainless steel pads which would help distribute the weight of the saw on
to my asphalt driveway and I thought that having the bolt heads on top of
here would be kind of nice because if I need to change the the leveling feet at
all you know steel on a steel would turn a lot easier than me trying to turn a
whole solid piece into the ground and lift up that way so low friction that
was a good thing with the leveling part bad thing with that is that low friction
if any load is applied or any kind of pull force is applied to the saw bed at
all like as I am when I'm pulling logs on to the mill it's really easy to have
the whole bed just slide and what ended up happening a lot of times these things
slide and fall off fizzle pads and land in the driveway and then start sinking
so that's why I added these concrete blocks just in case these these both did
slide off they wouldn't fall through my driveway and it also gave me a little
more height because I figured if I'm gonna be adding the hydraulic stuff to
this I'm gonna need a little more ground clearance than I had previously and just
being a little bit higher meant that the last boards off the mill you weren't
bending over nearly as far which is kind of a nice thing so my plan for the
living feet is gonna go something like this all of the discs are gonna get a
hole drilled in them and then a pin installed that's gonna go into a hole in
the bottom or I guess the top of the bolt the bottom of the foot or whatever
that's going to lock the two pieces together so this slide is one piece like
a little more friction up against weirdest thing is sitting on which is
going to be kind of nice I'm also going to drill the hole in the bolt a little
oversized so that way I can't take up any misalignment if the mound the ground
isn't totally flat or whatever so there's a little bit of play
side-to-side this hole isn't deep enough at the moment but while I move the whole
bed over I'll have the whole thing off the ground a little bit now I'm going to
take all the bolts out sequentially drill the holes and then get the new
ones installed so the good time for that and in case you're wondering why I don't
have my blocks turns long wise that's because it's a lot easier to clean out
between all of the bunks when there isn't some stuff in the way I always get
the comment about dust collection and the stuff coming
the shoot why I don't put down a bag or collect it or do anything with that the
truth is the stuff that comes and makes it out of the chute as the easiest stuff
to clean up guys grab a snow shovel and I just felt my wheelbarrow with that
stuff I'm gonna be out here anyway the longest and the most ridiculous amount
of time spent out here doing cleanup after milling is getting rid of all the
stuff that ends up underneath the bed so the blocks oriented the way they are
right now kind of across the width of the bed dust so allows me enough space
between each block to kind of slip a shovel in there and get up any kind of
sawdust or any bark or any chips that might be between all the crossmembers in
the bed that's honestly the most amount of work there is when as far as cleanup
goes the stuff that comes out of the chute you know five minutes it's all
gone then you spend a half hour out here shoveling stuff up from between all the
bunks
stall I'm going to end this video here I still have two more leveling feet to
modify but I'm not super worried about that I can take care of those pretty
much whenever I made a lot of progress in this one a lot of things they're all
back together and speaking of kind of back together everything that I removed
as part of the last video when I went through and painted everything is now
pretty much back on there and now it's all about moving forward so next time
we'll take a look at the whole top section of the lift mechanism well do
all of the chain routing and the tension nerves for the chains and finish up
everything up there to complete the whole lift system so all that will come
together next time so thank you as always for watching I greatly appreciate
if any questions on the sawmill or anything back in the shop please feel
free to leave me a comment supposed to be happy answer the questions you might
have until next time happy woodworking
