It is called an "axle slider". Maybe someone can correct me if wrong,
but all it looks like is a section of angle iron with spring hangers
welded on it. This seems like it would be handy when building a
trailer to "slide the assemply with the frame upside down to the exact
spot where the centerline of the axle is the same distance from the
tongue on both sides, then weld the angle.
I am just throwing out questions trying to learn. I may or may not
build this thing anytime soon but I wonder since this is a critical
weld area if I could get a piece of angle, say 2x2x3/16, have an
experiecned welder weld the bracks to the angle after I have tacked
them in the proper position, then, once the "sliders" are in the right
place, drilling and taping theangle through the bottom part of the
frame tubing, bolting it, then also welding around the angle?
By the way, I checked that metal, it is 3 inch square tubing 3/16
thick, so not as heavy stuff as I once thought but the price was right
for 10 bucks fo 4 10 feet long pieces.
Just thinking out loud here. Is there any advantage to using one of
these "sliders"? |

There is another advantage, as well as simply keeping the spring
brackets in line and supporting this higher stressed area--if these
are welded or bolted on right, then they'll also be able to be UN-
welded or bolted, and then moved if you find that you need to
reballance the trailer for some reason--like you decide to cut off 2'
or add heavy folding ramps at the back end. I think they're an
excellent idea.

Does my idea of drilling and taping the 3/16 tubing for the frame seem
like it is doable and will be strong enough to hold? (I cant see how I
would get a nut insde that tubing so the only way I could see was to
tap and thread.
Speaking of back gates, if a person added one later and it was heavy,
I assume you would need to move the axle even farther back to the rear? |

I'd be worried about it. I'd be more likely to weld a nut on the
angle and go through both sides of the tube.

Yes.

I'd be worried about it. I'd be more likely to weld a nut on the
angle and go through both sides of the tube.
To add: the most force here is the weight of the trailer and load
straight down, keeping the tube resting on the angle. The joint is
then only involved in keeping the pieces from sliding, which is why I
think you can get away with bolting this joint. Also, the hole
through the middle of the angle will be about 1" up, where the bolted
joint is getting some support from the tube wall perpendicular to the
two side walls the bolt is going through, making it less likely to
crush. If you can look for other places like this in your
construction where the bolt or weld is not taking the whole force but
is merely keeping pieces in place, you're better off.

I thought of that. You would need to put some type of pipe in the tube
to keep it from colapsing I guess. I dont know how I would drill
through it. All I have available is a hand drill.
If I could figure out a way to get a nut on the inside of the tube,
would that be better than just threading the metal? Maybe I could
drill the required hole in the bottom of the frame tubing, and somehow
fish a nut welded onto a small 3/16 plate into the tube to the hole.
Run the bolt through the angle axle bracket, into the hole of the box
tubing and screw it into thenut/plate inside the tubing.
What do you think? I can see an advantage of using angle in this case
if a person were to do that. |

Do I have to drill thought the whoe tube or can I just one side as
discussed previously? WOuld this "sliding action" as you described be
the same principle as placing the A frame under the actual trailer
frame,touching bothe the trailer sides and trailer front? (If that
makes sense).
Would drilling a hole in the center of the spring hanger and bolting
just the spring hanger to the trailer tubing be a good/bad idea? |

Welded on the surfaces parallel to the lentgh of the trailer only.

Here's the Dexter Axle service manual for common axles:http://dexteraxle.com/i/u/1080235/f/6-8K_Service_Manual_3-08/600-8K_C...
Also, check this out:http://i.b5z.net/i/u/1080235/f/Design_Considerations.pdf
Study up, quiz on Monday!
Where did you see that about only welding the parallel surfaces? I
could not find that.
Is it still a good idea to have the brakets welded to a piece of 2 x2
3/16 angle then weld the angle to the frame? Would the "weld only the
pareallel surfaces to the frame" still apply? |

I read it in some Dexter info when I built my trailer. It's somewhere on
the site. The hanger brackets will probably be 3/16" or 1/4" steel. I'd
go with an angle thickness of 50% or greater. Lots of stress on potholes.

What kind of trailer did you build?
So if 50% 3/16 would be ok? Maybe I should not use angle? |

Quote: Let the flames rise about not removing the head...now.
?!?? I can understand on a turret head, with the head way out on the
end of the overarm, but for a CNC? Why?
Note to Stryped: notice what he's using for hold downs--straps are
nice, the 3" ones hold pretty good, but when you really need to keep a
few tons in place, there's nothing like chains...

Why didn't I, or why was I worried about it? I've always heard you remove
the head for transport. I got the machines for a steal, with limited load
out time & resources, so I winged it. I felt comfortable about the load &
rigging.

That's really why I posted the pics, the seriousness of proper trailer
design. That sinking feeling in your gut just thinking about loosing this
load should keep you scared enough to do it right.
The only reason I used the web strap was to keep the shaper from scooting
forward when braking. Plus, I was out of chains. Web straps are good for
lighter, easy shapes to tie down. Loads of wood or steel stock. I'm
breaking the rules by using the strap at an angle. Should just be straight
over. SteveB has plenty of rigging experience; he can tell you more about
it. |

Why were you worried. I've heard of a lot of people flipping the head
over to get the height (and center of gravity for easier trailering)
down. If the trailer is stable and you don't need the height to get
under a door or whatever, why worry?
I could see, though, if you were worried about the forces on the
knuckles of a regular J-head. But even then, I think it's mostly a
judgement call thing. Some people support the head with a piece of
wood between the head and table. Others say that puts too much
pressure on the table jack mechanism.
Was out driving one day and saw a flatbed truck with a 1/2 dozen J-
heads on it. All had the heads on, upright, unsupported.
