[bolger] Re: trailer design for Idaho
I built a 20' trailer this summer for my boat. It's actually not very hard.
I used 4" channel iron. (plenty strong for a 30' trailer with 1200 lbs.
load ) It comes in 20 foot lengths so you'd need 3 pieces. I used 3"
channel between the 4" rails since it fits into the 4" nicely. Start out
with a basic box frame. Look on your plans and find where the Idaho starts
to curve towards the bow. The length from the aft end of the boat to this
point is the max size of the box. From this point, simply cut two 1/8"
slices in the sides of the channel about 1" apart. (I used a 4" grinder.)
With these you can bend it together in the front. Run a 3" Box iron about
5' long for the tongue. It should extend 3' past the bow. This also fits
nicely between the 4" channel, use a 3" channel to support the aft end of
the tongue.
I welded the cross pieces to match the bulkheads on the boat, then built 2"
wide horizontal supports out of 4 layers of 1/2" plywood. No longitude
supports used. This is claimed to be the best way to support light weight
plywood boats with thin bottom sheeting.
Look up Northern Tool & Equipment and order a catalog at
http://www.northern-online.com
They carry axles and all you need to set up the trailer. I bought their
2000 lbs. axle kit for $120.00. Very nice setup and comes with everything
you need including springs brackets, etc. Just buy tires & wheels. If the
boat will weight 1200 lbs., the trailer will come in at 500 - 600lbs so the
2000 lbs. axle should work fine.

Derek:
You've got me. I can see where all that weight would need to be supported,
but obviously you can't ballance the boat on the keel. I am guessing you
would want to have to boat sit on it's keel and it's bottom at the
bulkheads. It might be worth faxing PCB at: (978) 282-1349.
Sorry I couldn't be of more help.

My Dad has built four boat trailers over my lifetime. These range from
one built of heavy guage steel pipe before I was born to a custom fit,
galavanized painted custom one for a Boston Whaler Montauk. The best
seem to be made from steel channel beams.
The hardest part of trailer building seems to be the springs, axles and
hubs. All of our trailers used wheel bearings/hubs from early sixties
Rambler automobiles; Rambler used bolt on front hubs. You could then
make your own axle pretty easily by welding a plate to the end with the
bolt pattern. these have gotten pretty hard to find (at least where I
grew up in South Carolina). I remember a late-seventies weekend when
we visited several junkyards and picked up three sets for potential
future use. He gave the last set to a friend about four years ago.
Bernie Wolfard trailered his Idaho, I think (seems like I remember
seeing pics in his newsletter about this). These long, narrow, light
boats can actually hang well of the back of the trailer if supported by
long bunks.
Here in Florida, boat trailers and parts are a huge business (and
trailers are really cheap). If you run a search under Lycos or others
for "Boat Trailers" you'll get quite a few to look at. All of these
places sell parts, Including springs and hubs.
Good luck

Hi Chuck
Does the Glen-L book cover designs suitable for the Micro? I'm sure I read
somewhere about a requirement to support the keel, rather than using the
usual carpeted beams. Come to that, does anyone know of Micro-specific
trailer plans?

Jeff:
When I built the trailer for my Tennessee, I started with an old sailboat
trailer. I had only to extend the tongue ( using 4" X 1/8" box beam ) and
add some bunks of 4X4 pine covered with indoor/outdoor carpet.
Look at the tires. They will have a load rating. The ones on my trailer
had a rating of 710 lbs. they were 8"X4" I think. Not very big at any
rate. I have hauled that boat thousands of miles on those tires. I have
seen pretty good trailers made from old pickup axels. In fact you can use
the springs too. Alternatively, look in the yellow pages under trailers >
parts, and you can find dealers who will sell different size
axel/spring/wheel sets. They should be able to match your weight
requirement. Then just build a frame out of box beam or channel iron.
Jim Michalak has a discussion on building trailers:

Glen-L has plans:

I would go with the series 1700 single axel and extend the tongue.
I hope this helps
