Building a Dog
Sled
These instructions are based on
a sled building project done as part of our vocational
education program. We,I, made mistakes and I have tried to
point out major flaws in these instructions so that it might
save you from making the same blunders.
How did I learn to build dog
sleds? Well, I looked up stuff like this on the internet,
talked to a neighbor who had helped build them in the past,
looked at photos of different sleds, read a sled building
booklet from the extension service, and looked at a couple
of broken down sleds by my neigbor's house. Then I got some
hardwood and gave it a try. It came out pretty good so the
following semester we made one in shop class. The students
were less than excited about making a dog sled, but I think
it was still a worthwhile and interesting project and it
made a lot of money for student activities when we raffled
it.
I have been using the first one
I built with my two dogs and other than breaking my brush
guard off during an early training run the sled seems to
work fine. Of course I have nothing to compare it to never
having stepped on any other dog sled.
These instructions are for a
tough, but flexable medium heavy duty sport-utility type
sled. My finished sled weighs ???? (estimate 60 to 70
lbs).

If I can build a dog sled then
you can too!
Step #1.
We purchased a large rough-cut 2x10x16' hickory board. It
was very expensive ($178.36). I understand that ash is
better and birch is just as good and oak works too. I tried
making my own birch board from a birch tree, but it is a
long hard ride to the trees from Nunap and all I could find
were crooked and knoty.
There was a lot left over from the board and, I beleive,
a ten footer would be enough if I were extra careful with
the planning and cutting.
Cut out the following pieces from your board;
Two 2"x1"x8 ft. for
runners.
Two 1"x1"x8 ft. for the
rails. A little less than 1" thick is OK.
Seven 1/4" to 3/8" by 2" by 8 ft.
slats for the bed of the sled.
Four or five very thin (less than
1/4" ) strips about 6 feet long and 3/4" wide for the
handle bar (to be laminated).
These are all the parts that need to be bent. You need a
steamer and a bender before going on to the next step.

sled parts.
Step #2 (steaming)
I fashioned a simple steamer from two old rusty barrels.
As can be seen in the photos above I cut one in half length
wise and cut rectangular holes in the ends of another.
(Make sure there is no flammable fumes
in the barrel before cutting - jig saw works, torch
is faster). I got the idea from "Building a Dogsled" by
Marsha Million (Circumpolar Press, Anchorage, AK). I am sure
there are some much better steamer designs available, but
this is what I had.
The lower half barrel is for the fire and has a hole on
the end to push firewood into. the upper barrel is filled
with water up to the edge of the rectangular holes. When the
water is boiling I put the pieces to be bent through the
rectangular holes so that the sections to be bent are inside
the steamer and cover the holes with rags to hold the steam
in.
It took about four hours before I could bend the wood
without hearing it crack. A couple of the handle bar peices
cracked because they have such a tight bend. That is why I
recomended in step #1 cutting a couple more than you will
probably use.
|
Step #3 (bending)
Build benders for the runners, rails, slats and hanlebar
using whatever boards you have around. I tried to take a
short cut and build a wide bender to put all the runners and
rails and slats on together and another for the handlebar.
That was a mistake, next time I will make two binders -- one
for each runner.
The curve of the bender should be a few inches steeper
than you want the runners to bend because they tend to relax
or streighten a little after being removed from the bender
even if they are completely dry. A 12 to 15 inch rise in
front should be good for most sleds.
I blocked the runners into place on the bender first and
then bent the slats and rails all together over the runners
because these parts do not need to be bent as much as the
runners.
The handle bar needs two 90 degree bends and I found this
to be impossible except with very thin and well steamed
strips. I bend several thin strips together. Some break as I
block them in place, but enough do not break. The good ones
will be laminated together with wood glue to make the handle
bar about a half inch thick.
The width of the handle bar bender should match the
outside width of the sled. I made mine 21 inches.

The above four photos show us
bending and blocking and tieing parts to our
benders.
Step #4:
Next, while the bent parts are left
in the corner of the warm shop to dry for a couple of weeks
we go on to prepare the other parts. Many parts are cut
oversize a little to be cut off flush later. I will use the
measurments for my sled here, but make adjustments to suit
yourself.
Stanchions:
Need six (3 pair) of these cut 2 inches wide by 1 inch thick
and cut a little longer than necessary.
One pair should be about 36 inches
long, the
second pair about 27 inches long,
and the
third pair only 18 inches
long.
Cross-pieces:
Need four 1 inch by 1 inch by 21 inches (width of
sled)
Front
Cross-piece: Need one wedge
shaped cross piece 20 1/2 inches long by 2 inches wide. One
side should be 3/4 to 1 inch thick while the other side is a
little under 1/4 inch thick.
False runners:
Need two of these 2 inches by 1
inch by 4 feet long. I was thinking I would make my next one
closer to 5 feet long for the added strength. Cut the front
of the false runners at an angle to make it look
better.
|
Step #5:
You still need to cut the braces, but those can be done
later.
Round off the bottom 3 inches of the two longer pairs of
stantions and the bottom 2 inches of the short pair. The
longer pairs need to fit through the false runners and the
runners while the short pair only has to fit through the
runners.
They need to be rounded to fit tightly into a 1 inch
hole. I did this by cutting the edges with a band saw and
then rounding them off with a large belt sander. I bet a
lathe would work better.
Extra Note: On my first sled I made squre holes and
trimmed part of the stantion to fit in the hole. I had much
difficulty making the square holes and even more trouble
getting the recommended tight fit. Please remember that I am
not a professional shop teacher -- the only time I ever had
wood shop in school was when I was in the seventh grade.
Anyway, I have decided that it is easier to make a round
hole and round off the stantions. At least until I learn
some new wood working techniques.
While you are working with the stantions go ahead and
sand off all the sharp edges and sand the sides smooth. I
used a belt sander with a fine grain sand paper to make it
look good in a relatively short time.

diameter hole. Below: Start assembly by attaching false

Step #6:
When the runners have had a couple
of weeks on the benders then take them out and sand them
smooth. I do not recommend rounding the edges of the runners
or false runners, but rounding the edges of all the other
parts is a good idea, I've been told, to help prevent
cutting and tearing of clothes and flesh in case of a crash.
The false runners should already be sanded.
PS. The "false runner" is the peice of wood that is about
half to two thirds the length of the runners and is bolted
directly onto the runners. Foot pads will be added to the
false runners to give you something with traction to stand
on.
Need eight 3/8" by about 4" bolts
with smooth heads and washers/nuts.
|
Step #7:
Place the false runner on the
runner, line up the back edges flush and decide where to
drill three holes to bolt it down.
You want at least 24 inches
sticking out behind the rear stantions. On my next sled I am
going to leave 30 inches sticking out to stand on to make it
a little more comfortable.
Use a pencil to mark exactly where
each stantion will go so that you do not place a bolt where
you will want to put a stantion later. The small stantions
should go on the front just a couple of inches up the curve
(they will angle back a little). Once you have decided where
to put the rear and front stantions then put the middle
stantions a close as possible to half-way. The middle
stantions should also fit into the false runner just like
the rear stantions.
I put one bolt as near the front of
the false runner as possible, one between the stantions
about half way and the third near the back end of the
runners.
