Just for info--- for those with beat up fenders.. I have a 10 year old 18 ft 10K car hauler. Old sheet metal fenders have seen better days after hauling backhoe , bobcat, connex boxes... Pretty beat up. I had considered buying fenders made of 3/16 inch plate but they were around $500. I thought of making fenders from 10 inch c- channel, but they would be pretty heavy. While checking around i ran across something called JUNIOR CHANNEL. This was a 10 inch c- channel with 3/16 inch thick web and slightly thicker flanges. Weight was 8.3 pounds per foot .. so a 8 ft long section welded into a fender shape would be about 65 pounds per side.. PERFECT.. I bought 20 ft at the local Steel Yard and it was around $200. Didnt take long to cut the three pieces to make a fender with flat front and rear edges. I had a few scraps of 3/16 inch deck plate which i used to fill in the opening at the trailer deck... Getting the old fenders off was the biggest problem !!    ------------- Like them all, but love the "B"s. |

Well, Steve,,those look Great and no doubt will withstand a lot more punishment that all trailers that get regular usage will. I always shudder against that first dent with a new trailer ,,,,and after that first dent,,,,wwell,,,all them other dents come way too dang often,,,,  Good Job,,,,!!

yea... had a few dents.. then SON dropped a 20 ft connex box on the fenders and smashed one down to the tires... had to use a bottle jack to get it up high enough for running clearance.... NEW fenders should take as much load as the tires can support !! ------------- Like them all, but love the "B"s. |

| Them there are some very impressive fenders, they look like they would have been factory, good job, Ill have to remember your advice when I rework one of my round the farm trailers that get routinely abused. Thanks for doing the homework and passing it along |

Bought this trailer used several years back, is due to repaint currently as time does not wear well. It also had the Tin Soft fenders where I added Tread Plate replacements from a Trailer Supply company.   Found them on a search for trailer fenders and were a direct install to OE Mounts. Standing up really well for beatings I have given.

While visiting the trailers subject,,,I've always wondered what engineering formula is used to determine the location that is used for placement of the axle,,(S) on the tralier frame,,,?? Like DMiller's trailer that has both axles way back from center of frame,,,,????

| 60/40 axle location works well on 20'. |

| The trailers I have built are made to my specs to haul a certain item, like an antique tractor. My axles are waaay back so I can drive the tractor on and place the center of the rear wheel over the center of the rear axle on the trailer. Makes my tongue weight correct and trails perfectly. Works well hauling cars to when I've had a dead one. |

60/40 on the bed length is a GENERAL rule.... As Dr said, the most important thing is getting 10- 15% of the WEIGHT on the Tongue ..... weight distribution is different if your carrying a tractor or a load of gravel.. ------------- Like them all, but love the "B"s. |

single axle, 60% back from the front of the BOX ( NOT the tongue...) tandems, 50% back these are the usual 'standards' posted. Now horse trailers and boat trailers are different......don't know why... My 5by8 trailer that I make are 100" long, so axle is 60" from front, dang EASY for even me to remember. They haul very very well. ------------- 3 D-14s,A-C forklift, B-112 Kubota BX23S lil' TOOT( The Other Orange Tractor) Never burn your bridges, unless you can walk on water |
