square tubing axle

[BigDaddyCool]

do i need this with a square tube? or just drill a hole in the tube?

[G-force]

A flat plate with a hole should be welded on to locate the axle on the springs. The one you have pictured has the sides bent down and radiused for a round tube, the ones for a square tube are just rectangular and flat with a center hole.

If you don't need the extra spacer just drill a hole in it, a lot of them come that way.

thank you

I would weld the plate on - You would be drilling a fairly large hole exactly where you don 't want it for strength purposes, plus it will allow moisture inside the axle which will eventually rust it out from the inside out . . . . you'll get no warning when one wheel is about to fall off

Never seen it happen. Axles are thick enough that the hole isn't an issue.
I've changed them for a lot of reasons but never that.

drilling one or two holes would be good for air circulation and removing condensation...

making a frame in tubing with no holes for moisture to escape will actually promote rust.

by the way i'm welder/fabricator

News to me

I have 6 different trailers of all descriptions here on the property - About the only single thing they all have in common is there are no holes in any of the 10 factory built axles

For what it's worth, I agree with Don.

I designed, built and repaired trailers of all sizes for over 15 years, so you've obviously seen more than I have.

Closed tubes with moisture in them can rust out. Closed tubes which are clean and dry inside stay that way, and seem to me to be unlikely to rust.

My guess is that factory-built axles with closed tubes are decently dry when built, so no hole for drainage is needed. Add a hole on top, and you may change that.

Personally, without the benefit of any specific experience or authoritative references, I would want the plate added; however, I can certainly believe that many just have a hole drilled in them.

where i work we always drilled holes in tube, post ets...

aluminum or steel

because of condensation, hot and cold will make moisture in enclosed tubing...

and we build 45' Dump Trailer , flatbed, transfer, logging etc about 6000 a year..

we have seen so much water in bumper that when it froze the bumper craked,

thats why they drill holes in them, waranty issue


rust takes alot of year to go thrue steel anyway

Not possible - If there isn't any humidity already trapped in the sealed tube, then you can't condense any in there . . . . it's sealed

You never picked up a 'message in a bottle' on the seashore? The paper inside is dry
