OK, I went and looked under NT trailer and the tongue extension goes back and is bolted to that crossbar under my spare You could probably run the extension back to that cross member/bolt of the spare tire mount. I flipped the axle to the top of the springs for a lower deck, but sounds like you'll be going the other way. For me, the spare mounted underneath is scary...
So I spoke to my mechanical engineer buddy and he has told me like usual, you have over thought and over engineered the solution. So I think I have the tongue issue licked..... I ordered a 24" 2" raw receiver tube to start.... It is 1/4" steel and very well made for 31 bucks including delivery. In honor of Adam West who went skiing today... stay tuned to this Bat Channel and Bat Station.... I have lots of holes to drill and some 1/4" plate to cut and weld. I'm going to extend the tongue 12". More tomorrow
The NT & HF trailers are designed for freight to you then assembly via threaded fastners thus the weird design's not so weird. A welded trailer never would be made like that what with the lack of a proper front clearance distance. Beware of extended receivers as a properly extended tongue's much stronger. I'd get it right (dimensions) then weld it!
I'm using the tubing to extend tongue, not the receiver. It just was a quick way to get a piece of 2.5x2.5" tube without having to buy 20 ft and cut it in the parking lot to get it home.
I have Pacific Steel here in ID, and I get one free cut when I buy a full stick, and they have trailer parts too I've cut a lot of steel with a hacksaw and they let me cut stuff with a hacksaw from the "shorts" rack, so I got just what I needed...until some nimrod customer cut himself and bled all over. So now I have to buy the whole "short" or a full stick. I ended up buying a HF portable band-saw...wow For many trailer builders, bulk trumps engineering, as long a your tow is not a Prius. I'm with you though, I take a little more wall thickness if I don't have but a 20ft piece. Pacific as a lot water jet cut plates of varying shapes/thicknesses (6"x6"x1/4" for $4) that I buy and make corner gussets, etc.
We only have two places around here. The nearest place despises non industrial customers and charges 40 bucks to make cuts. Besides the cost, you have to wait for an hour or more. The second place is nicer but with traffic, it can take two hours to get there. I bought an inverter and usually use my angle grinder to make parking lot cuts. I have a Makita battery powered angle grinder but it takes a while on 3/16 or 1/4". Back in the day, I made lots of stuff from steel, but not anymore. I bought a plasma cutter, to bad it isn't portable. Well the unit is but it needs a 2hp compressor or more.
A little progress today including a lot of hole drilling. Just couldn't get motivated to finish today.
Looks familiar... I thought you'd cut that flange off of the extension though. Looks you are making a cross member for the back end of the extension, will that be bolted on too I found the extension bar I used to be thicker than the triangle's U iron and put washers under the top plate, but probably could have flex everything to tighten up without the washers. The washers can be seen in the pic IN MY POST #17 http://advrider.com/index.php?threads/extending-my-utility-trailer-tongue.1231761/#post-32462741
I remade the vee mount using 1/4" x2" plate steel and I'm supporting the tail of the new tube and bottom with 1/4"x 3" plate top and bottom. I finished today, the parts are outside drying. I haven't cut the flange off because, I'm not sure if I will like the result yet. I'm still thinking, long term of extending the tubing all the way under the trailer bed to the center cross member. I'm planning on doing brakes and a new axle. That would a good time to do it. The picture shows the bottom of the new Vee plate, you can see the side spacers to give me the 2.5" height from the existing 2.25" side rails to the 2.5" I need. I will assemble it tomorrow and takes some pictures. It turned into a lot of work for as measly 12". I know there is a joke in there someplace....
I usually weld it all up and then paint it. .... it looks like a solid addition to me I'm just kidding. Trailer building or modifying seems simple from looking at one Until you actually start doing it, without a shear, brake, band saw, sand blast room...
The Vee is welded from the top side. The rest is bolted on. You are not kidding. The more tools I have, the more tools I still need. Back in the day, I did everything with a old Sears buzzbox, angle grinder and hacksaw. Here is what it looks like just set in place. I will bolt it on tomorrow after the paint is hard.
That looks like good garage work to me buddy. likely stronger than the rest of the trailer. And yes buzzbox and grinder I finally upgraded to a worm saw with a metal cutting blade... wore it out Bought a chopsaw at northern tools Wore it out Back to the harbor freight grinder haha
Done except minor reroute of the trailer light wiring. It is exactly perpendicular to the front of the trailer.
I just took it for a spin. What a huge difference in the ride, less bounce and much easier to back up just using mirrors. Trailer behaves like it should now. I should have done this during thee original build.
