My local trailer building supply house has "high speed stub axle
assemblies" with a stub 4"long and 1/3/4"in diameter made so you can build your own axles. I assume they are designed to go into some type of pipe or tubing and welded in place but what kind. The u bolt spring hangers they sell are for 2 3/8"dia . This leads me to believe maybe 2"schedule 80 pipe which is 2 3/8"OD but 1.90"ID. Is 0.015" play too much, should they be wrapped with shimstock? There is 2 3/8"tubing available but the ID is 1.749" so they won't fit that. The seller (princess auto) has no idea either. Thanks |

Thanks I'd go with 2" Sched 80 in a pinch, but IIRC there is a DOM tubing that fits them exactly. Try metal supermarket. I think it is 2 1/4 inch DOM (1/4 wall). A lot of these axles have been used un "U" chanel axles too. And in square tube. In Sched 80 I'd just put a few "weld blisters" around the shaft to make them fit snug, and drill a few 1/2" holes through the tube and plug weld them. In DOM I'd fasten them the same way - at least 4 good plug welds. Keeps the HAZ away from the end where the axle tube and stub join. -- Posted via a free Usenet account from http://www.teranews.com |

Just buy the built axle if you are looking at a standard single wheel axle design. You can't build a decent safe axle for what they want for one, unless you have an exceptional scrap pile and the know-how to do it safely (which, if you are asking....) Can you jig up the stub axles to keep them in line? Reliably? And weld them in place accurately? Just askin'. Better to realistically assess the chances now, than to spend a bunch of money, then have to do it all again for the next try. Cheers Trevor Jones |

Axles are critical and very inexpensive. Buy a Dexter or some such,
made to your spec, and be happy forever. i On 2008-04-04, Trevor Jones wrote: mark wrote: My local trailer building supply house has "high speed stub axle assemblies" with a stub 4"long and 1/3/4"in diameter made so you can build your own axles.

The premade axles include installation kits - all the spring saddles, springs, u-bolts, shackles, frame saddles and brackets needed to install it safely. That was exactly my experience. New 6,000 lbs axle, new tires, new electric brakes, new mounting hardware, new springs, made exactly to my spec, just appx. $600 delivered. It works great and does survive 6,000 lbs of weight, at least it did so the last 2 times I tried (both times with power supplies that weighed 4,500 lbs each). Making my own axle? Not for me. It would have cost me a lot more to make homemade, and I would have missed some gotcha that would ultimately cost me dearly. There's way too much fabrication involved, and you have to get ALL the little details right - or you will deal with failures that could have multi-fatal consequences. Yes. And fabricating a suspension from scratch is reinventing the wheel and will cost you dearly in parts and time. The axle company buys all these pieces in bulk, and you will save in the long run. And they know exactly how to put them together so that the axle does not fall off if you hit a speedbump. The axle tubing has to be the right steel for strength, the welds holding the spindles on are critical and tricky, and the axle needs a 2 or 3 degree bend in the middle /at an angle/, to provide a bit of toe-in and camber so it tracks right. They know how much to tweak it, you would have to experiment till the trailer tracks true. They also heat treat their axles after welding, not something available to a typical home shop. The main reason why my trailer works so well for me, is that I started off with two very well made items, the bed and the axle. i |

Shims will make no difference once the unit is welded together. You plan on cutting the trailer up when you are done with it? Otherwise, it may well end up on the roads. Better to have the standardized (and proven) axle. Fill yer boots. Cheers Trevor Jones |

You failed to mention that in your OP. It was an interesting thread anyway. Fun to watch all the answers you got. Unfortunately nobody asked what you were going to do with the axle. Seems like everybody assumed you were going to put it on the road. B |

Mark, for your situation then, I would use a piece of metal pallet strapping
as a shim, drive the stubs into the pipe, and weld around. Adjust fit as required in a local area around the shim with a die grinder. RJ "mark" wrote in message ... On Apr 4, 3:21 am, Bruce L.

If the axle does not have to be tremendously strong, just use the rear axle
out of a front wheel drive car. Some models would make great light trailer axles, and they're all but ready to use. RJ "mark" wrote in message ...

The OP was looking at the usual pipe size tables. Typical one looks like:
http://www.intercononline.com/welding/schedule.htm Schedule 40 pipe is designed to have an ID very slightly larger than the nominal pipe size. So 2" schedule 40 is 2.067". Schedule 80 was a "extra heavy wall" pipe, uses the same fittings (OD related), sothe ID is well under 2" Ronald Thompson wrote: clare at snyder dot ontario dot canada wrote: On Thu, 3 Apr 2008 15:09:02 -0700 (PDT), mark wrote: On Apr 3, 6:41 pm, clare at snyder dot ontario dot canada wrote: On Thu, 3 Apr 2008 14:01:01 -0700 (PDT), mark wrote: My local trailer building supply house has "high speed stub axle assemblies" with a stub 4"long and 1/3/4"in diameter made so you can build your own axles.

I was watching the other replies, no one seemed to pick up on the fact
that you misstated the the difference in sizes. The schedule 80 is indeed 1.90" but the axle stub is 1.750" or .150" smaller (10x larger play than the .015" listed in your post). That will indeed require some sort of shimming or massive plug welds to accommodate the misfit. mark wrote: My local trailer building supply house has "high speed stub axle assemblies" with a stub 4"long and 1/3/4"in diameter made so you can build your own axles.

What is DOM? Drawn Over Mandrel. All pipe and steel tubing is made from strip stock that is folded into a tube and the seam is butt welded. The mandrel drawing process smooths out the welding seam left on the inside of the pipe for extra strength, and makes sure there are no burrs on the inside of the tubing. For electrical conduit burrs on the inside are very bad, they cut the wire insulation and cause shorts. For telescoping tubing internal seams are bad, because they block you from sliding the next smaller tubing inside that one. -- Bruce -- |

They use 1-3/4" stock because it is the smallest (read cheapest material
cost) that will turn down to fit the 1.71 grease seal and bearing sizes that is standard on heavier duty hubs. If I were in the business of manufacturing axles, I'd have my supplier turn the spindles to give a tight fit on the axle tubes I needed for strength and cost. That might not be 1-3/4" raw stock. mark wrote: On Apr 5, 11:55 pm, RoyJ wrote: I was watching the other replies, no one seemed to pick up on the fact that you misstated the the difference in sizes.

And when the day comes that you or your estate sells your trailer...will you be willing to accept the liability if the buyer or driving public is harmed by your POS when it self destructs? Lawyers love guys like you....and make alot of money off you. Buy the axle. TMT Everybody talks about home built trailers self destructing. I've seen more factory built crap fail than the usually overbuilt home-made trailers. The home-made trailer might eat tires at a phenominal rate - but generally what I see is a lot better than the wall-mart / northern tool / home depot crap. ** Posted from http://www.teranews.com ** |
