Off road running gear for Miller Trailblazer

admin

Does anybody know the axle size of the wheels on the Miller off road running gear? Just made an off road cart for a Trailblazer 325 with  ⅝" steel axles. One axle bent on one side, nearest the front. The pneumatic tires are 13" in diameter. I think the wheel "thimbles" (or whatever they are called ) are too long , resulting in the wheel being a little too far from the frame. Or is the axle diameter too small for the weight? Thoughts?'
Reply:Did you make a tandem axle tlr? If so did you make walking beams so both axles take the weight evenly? 5/8" sounds a little thin for your purpose. Go buy a couple of boat trailer axles with the 4 hole 3 3/4" hubs then cut out of the middle to shorten them then weld them together and grind the weld down smooth. You don't need to worry about camber in this case. If you can find some pipe that will fit snug on the axle tube, cut a piece about 12" long and split it lengthwise. Then trim the two pieces so  you have about a 3/4" gap between the two, then clamp on the tube weld each lengthwise. DO NOT WELD AROUND THE CIRCUMFERENCE OF THE TUBE. Then go buy some HF 12" tires and wheels. It's what I have under my welder tlr with a 700 lb Hobart on it plus the trailer weight, about 200 lbs.Ol' Stonebreaker  "Experience is the name everyone gives to their mistakes"Hobart G-213 portableMiller 175 migMiller thunderbolt ac/dc stick Victor O/A setupMakita chop saw
Reply:I used 2 x 2 x3/16 angle for the frame with one flange on top and the other to the outside. I drilled ⅝" holes just about exactly under the bolt holes on the welder, inserting the ⅝" axle. I assumed that the weight would be evenly distributed over the two axles. I think the problem is that the design of the wheels places the centre of the tire about 2" extra from where it would be if the spindle was flush with the side of the tire. Clearance could hopefully be controlled by washers, I assume. Yesterday I bought 4 tires on rims which have spindles flush with the tire wall. I'll get another ⅝" rod and hope I can find one with a higher carbon content. If that fails I'll try something else. It's odd that both axles didn't fail at the same time. Hopefully it was a manufacturing flaw in the rod.    I appreciate your suggestion and I'll probably try that route when I try a small road-worthy trailer build. That is my eventual goal. I'm only an amateur , trying to get the welder experience while having an emergency power supply for power outages. At this time I'm only looking for something to move the machine around my yard and I'd like the mobile cart to be as strong as possible but as light as possible as well. Thanks again mia2ofus. Much appreciated. Your  trailer sounds like a great idea.
Reply:5/8" axle is about the size for a Radio Flyer Childs wagon, 1" is still small for a Trailblazer,,My Trailblazer is on a donated boat trailer axle, and frame,,The spindles are 2,000 pound capacity.

Reply:I have a 302 Trailerblazer that I also use for emergency power. I store in garage on a custom cart I made. I wanted it off on/off road use too, so I got a $25.00 boat trailer that I modified. I set it up so my Trailblazer sets on trailer and then gets bolted down. It really works great for me. Here's the post I did on it.   https://weldingweb.com/vbb/threads/1...ailblazer+cart
Reply:Mine is also a recycled boat trailer. It had all 4" channel frame so I just cut it all up and started over. Bought the springs and attaching hardware and made the axle from some recycled spindles and 1 1/2" square tube. I really like the homemade fenders, they never get bent.

Reply:The ⅝ axles are only for a yard cart. If I get the urge to move it on the road it will be on a traditional trailer axle. I recently did more work on the cart, eventually using no-flat tires from Princess Auto. this was after two other tire sets were not satisfactory. I also sacrificed a clamp pipe with a ⅝ID and slid it on the axles to add strength and it seems to be doing fine at this time. I have yet to weld a handle on the cart and it's tough to get it turned around in the garage without that handle. I guess I'll always be looking for new options to make it work best for me.    Thanks for all the replies!

Reply:The first axle I put in my cart for my jacking equipment was 5/8"... had to push it out to 3/4" (You can see it's starting to bend in the bottom pic, it ended up with the same Princess Auto wheels that Lis2323 used). Can't say I'm too excited by pneumatic tires in the shop either. They go flat sitting around and are more prone to welding sparks. Those boat trailers could be narrowed down for storage if you went to the torsion spindle kits... a little pricey though.
