My shop is in the basement: It has a high ceiling, easy access to
the breaker box, and is comfortable all year around. I haven't had
too much trouble getting woodworking tools down there, but metal shop
tools are another story.

* There is a straight shot from the back door to the basement door,
about 15' away. The floor is constructed with BCI floor joists
24" apart, with OSB subfloor and oak hardwood flooring.

* The stairs are straight down, with no curves or landings. There
are double 2x10 stringers on each side, and a 2x10 stringer down
the middle.

This is why I told the realtor that the new place had to have ground-level
access to the basement. She found a GREAT house, that not only met
the several requirements I had, but delighted my wife as well. We both
sat in the car for 15 seconds after seeing the place, and said "We gotta
place
a contract on this, TODAY!"


* There is an egress window, 42"x44" opening, that opens into a
window well about 5' deep and 2.5 feet back to front.

I want to move a Clausing 5400 series lathe and Grizzly G3616 mill
downstairs. The professional riggers (the only ones in the area)
can lift the lathe to my backdoor with a crane, but will not take
it downstairs without my disassembling it. Of course the heavier
milling machine won't go down any easier.

I'm told that the stairs are rated for about 1000 pounds as is, and
I'm not sure of the 1st floor -- but I'll put 3/4" plywood down when
I move the equipment, so that will both add weight and hopefully also
redistribute it a bit.

My original plan was to add two stringers to the stairway and brace
every 4th stair with a 2x4 frame to the concrete floor. But that
was assuming the riggers would actually need to get 1000 pounds
downstairs all at once. And with the double stringers on the sides,
I'm not convinced that two more are really necessary. The basement
has an 8' ceiling height, plus the height of the BCI joists, and
there are 15 steps.

Here are my two notions -- comments and ideas are welcome.

1. Add angle irons to each side of the stairway (over the existing
double stringers on each side) and use it as a track for a wheeled
cart. The cart would attach to a winch, braced on the concrete slab
that makes up the patio/step outside the backdoor. If I designed
well, the cart could be used to wheel the machinery from the back
door to the basement stairs, then rolled down on the track. There
is still the problem of what the cart should look like, and whether
I should bolt something together out of hardwood or have a steel
frame welded up. I would use 1000 pound rated non-swivel casters.

You have to make sure this cart can keep the machine from tipping at
each stage
of the lowering. The lathe will go down the long way, so that doesn't
sound too tricky. But, the mill may be more of a problem. You don't
want it to start to roll over rather than roll down. Removing the head
might be enough to keep it stable.


2. Remove the window well frame, excavate an incline down to the
window, and surface with concrete. This may require some kind of
brace against the foundation to replace the window well (or maybe
that's not necessary). The benefit is that machinery could be moved
directly into the basement without using the stairs. However
the window opening would still be too small for a lathe, for example,
without disassembling it. I suspect this would be a very expensive
proposition, probably in the neighborhood of $ 5000.

A temporary grade change to the window well might be possible. You
aren't going to be doing this every year (or are you? It can get
obsessive.)
I don't know the 5400 contruction in detail, I'm guessing the bed is mounted
on a stand with the motor, etc.? It may be pretty easy to get the lathe off
the stand, and just carry that down the stairs with two guys. If you can
get the window frame out, 42 x 44" is a pretty big hole. If the column
comes off the mill, it almost has to go through that opening, unless it
is a Bridgeport clone. If so, the main base casting will be difficult to
wrestle through the hole. If it is a benchtop mill, it should be no
problem.
You might have to take the table off to get it through.


My garage is detached, uninsulated, not temperature controlled in
any way, and only has one 117 volt circuit, so switching the shop
location is not an option. I either have to come up with a solution
or resign myself to using miniature machine tools.

A year-round comfortable shop is a NECCESSITY, in my opinion.
It is also a good deal easier to prevent rust and other problems with
it in the house. So, the garage is out, unless you put a heater in there.
The wiring is small potatoes, in the end.
