I had a request to show some pictures and share some
information about my lathe and milling machine. I thought, 'why not' so
we'll start off with the lathe. I bought this bench lathe new in April
of 2017 which is made by
Jet. This company has
been around for many years and they sell a lot of different models of
lathes, along with a bunch of other metal and wood working machines and
equipment. I'm getting ahead of myself here so let's go
back to the day that it arrived to give you a better idea what I had to
deal with.

Unpacking and Assembly
The truck driver was kind enough to help me get these
crates into my garage using his pallet jack. And notice the larger one
is longer than normal, which made it challenge to move around. In fact
it's about six and a half feet long.
|
|
Check out how much this thing weighs? Now you can see why I said it was
a challenge.
The 'GHB' in the model number means 'Gear Head Bench' and
then there is four numbers after it. The 13 is how many inches of
turning capacity it has and the 40 represents how long of a piece you
can turn in inches.
|
|
Now that the crate is out of the way, it's time to lift
this onto its base. And Jet was thinking ahead here because those black
pieces in the foreground are going to help me with that. The plate mounts under the
center and the eye bolt goes through the bed of the machine and threads into it
the plate.
|
|
That's not shrink-wrap, it's packing grease. Every
critical surface had this stuff on it so it doesn't rust. I had fun
removing all of it :-]
|
|
Here I'm assembling the base and making sure it's
level. Now it's time to get that heavy piece on top of the base.
|
|
A forklift would've worked great here but
that's only wishful thinking. I started looking at the two pallets the
machine was
shipped on and I had an idea. If I were to raise the top pallet a small
amount and then cut the bottom pallet in half (arrows), I could slide
out that center piece.
|
|
Once the center was out of the way, I was able to
slide my hoist under it and lift the lathe.
|
|
Here you can see I have just enough room for the legs of
the hoist to fit under the top pallet (arrow). To lift the pallet to this height
was not an easy task. It took me over an hour of using a pry-bar,
placing a wooden shim in one spot, moving to a different corner and
repeating the process over and over again. I was pretty tired once I got
to this point because the whole time I'm lifting the weight of the
lathe, about 1000 pounds.
|
|
I took my time and moved a small amount here and there
to get my hoist into this position while the lathe was in the air. Not
really all that much fun because I could just see things going very
wrong in my head the whole time. In fact, I wondered if something was
going to fall while taking this picture.

Setup
Once I had all the bolts tightened down, it was time to
level the machine. I borrowed this precision level from my work and it
worked really good. All I did was tighten or loosen the adjusting bolts under the machine
until I had it where I wanted it. However, over time I will need do this
over again because things will settle and move. |
