Been thinking of building my own trailer because I need one and enjoy
building.
One question by the way, would it be stupid to put a dovetail and a
fold down gate on a 10 foot trailer? And if I did have a dovetail,
when calculating the axle placement using the 60/40 rule, do you
consider the dovetail in terms of the total length?
Most 10' trailers tilt instead of dovetail. It'll eat into your flat
bed surface.
As far as axle placement, you want 10-15% of the total weight of the
trailer on the tongue. If it's too light, it will tow like crap. Use
that rule for load placement, too.

What is a good way to tilt it? Most of the time I will just be hauling
gravel and things, but one in a blue moon I might have to haul my 8N
for repair or something.Not sure how well a tilt bed will work in
that cause.
I would like to make it longer but dont think I have scrounged enough
medal to make it any longer than 10 feet 6 inches.
By the way, what is the best way to determine that tongue weight? I
wont know how heavy it is until it is built. How do I determin tongue
weight on it? Is it possible to have too much tongue weight?
I was under the impression that you were building a utility trailer. It
sounds like you need an equipment trailer. I wouldn't suggest building an
equipment trailer as your first trailer. The stresses are much larger in
critical areas. Better to make a design mistake hauling a lawn mower than
a 5000# load.
As far as tongue weight, you can tell by looking at it with experience.
Here's a guide:http://www.curtmfg.com/index.cfm?event=pageview&contentpieceid=1347
When I built my trailer, I took numerous photos and measurements on existing
trailers & built mine to meet my size needs.

I am needing a utility trailer mostly. However it would be nice to
"once a year" or less haul my 1943 Ford 8N tractor if I ever needed
to. (probably never will). It weights 2, 500 lbs.
I have available some metal at work I can buy at scrap price. However,
it is beffy 4x4 1/4 inch square tubing. Is this too heavy to build a 6
fott by 10 foot trailer? Can I weld it with my Lincoln AC welder 225
amps?
I really appreciate your help and sorry for the questions. I just have
so many even after I have looked at hundreds of trailers and read a
few books.
What sort of lengths can you get?
4x4 x1/4 is going to be very beefy. But from your post on RCM you can
get a heck of good price on it.
For the length, I don't think a dove tail makes much sense. But fold
down ramps, or a gate might be handy.
Your welder should be more than adequate for the job. But are you?
What are you planning on for a deck surface? Diamond plate, or wood,
or?
Any way to source something lighter (say 1x3x1/
for cross
stringers? And then sheet the whole thing with steel diamond plate.
Or lay planking the length. I wouldn't worry too much about building
a tilt bed. Depending on your axles, you should be able to build the
deck pretty close the ground. Adding the tilt can be a lot of work.
And given this is your first trailer, try to keep it simple.
A low deck car trailer I built years ago is low enough that I rarely
use ramps to load onto it. Usually I can find enough of a rise in the
area to just drive onto the trailer. I think the deck is around 12"
off the ground. No beavertail.

I was thinking of wood to cut down on weight. I think I have second
guessed the dovetail.
Maybe no back but portable ramps.
Would a 3500 lb axle be heavy enough or should it be more since this
thing will weight alot because of the steel?
Admittantly, the most thing this will be used for is hauling river
gravel to mulch around my house. Maybe trees. But I would like to be
able to put my tractor on it in case I ever needed to.
There are 8 10 foot sections I believe. I think I can get it all for
80 bucks.
The steel you have is pretty close to 10 lb/ft. (pull out a book to
get the exact number).
If you used three full lengths, and used the same for cross stringers
you would need 30 ft for rails + 36 ft for the cross stringers.(2ft
centers) The 14 ft you have left would be pretty good for a decent A
frame tongue. That gives you 800lb in frame. The deck shouldn't be
too bad. 2x planking it will weigh around 175 lbs.
So say your total trailer weight is 1000#. Since you carry some of
your load on the tongue... A 3500# axle should be good for ~2900 lbs
of payload capacity in this configuration.
Certainly meets your needs. And a 6x10 trailer built completely out
of 4x4x1/4 is going to be stiffer than heck. You won't have to worry
about bending it.
Disclaiimer: This is all napkin math, and not just a heck of a lot of
thought put into it. 2 ft centers is probably overkill. You can
probably get away with a wider spacing given your materials. Wider
spacing would reduce weight. Also, much lighter material could be
used for your cross stringers. Further dropping weight. I would
venture it should be possible to drop the trailer weight to 750#
pretty easily without giving up any capacity. 2x3x3/16 is 5.59lb/ft.
That would drop 160#. Better spacing might drop 1 or 2 stringers so
there's another 70# maybe.

Thanks, this helps alot! Would you use angle 2x2 x 1/4 as cross
stingers instead? (I would have to buy it and it is about 66 bucks a
stick.
What about the weight of the axle, etc?
Would I have to have electric brakes?
My main concern is getting a trailer as cheaply as I can that will
service my needs for many years. (I tend to keep stuff).
Part of me wondered about going ahead and building a 16 foot dual
axle, but I would have to weld two of the 10 foot pieces togther.
