Cooper-that cut seems to be a long way from the table. Hope your mounting is good. I haven't understood what you are doing with the wheels but I thought I would just wait until they were done. I'm sure it will be good. Question-why did you decide to make such a large truck at such a large scale? The reason I ask this is that most mines seem to match truck size with shovel size. I think they like to load with 4-6 buckets per truck. If you load this truck with your standard excavator that will be like "filling a 5-gal. bucket with a teaspoon". Do you have plans for a larger bucket or maybe a larger excavator? Keep the pictures coming.

Bolt a piece of metal to your rotary table then mill a circular boss to locate your rims on center. Then you can place the next one on the table and it will be located. You will have to have a nice fit though. Make it big enough to have your studs for the clamps to screw in or double nut by using the slots then a nut to hold plate then long enough to clamp rim down.

Thanks Steve, I was thinking other end, was going to make a piece to chuck up in the mill and then slide into part. I guess what you said but up side down I think I'll go with what you suggest. I've been wanting to make a plate with a few holes machined into it that bolts to rotary table. Having something like that would give me more future clamping ability. I was planning on clamping part around bottom ring and also having a shaft (long bolt) up through center with plate to clamp from top also. Probably have to recess it so milling tools have clearance. Was wanting to use something around 3/16 for mill to get a small as possible inside radius on cuts. Plus the endmill I want to use has shaft same diameter as cutting blades. Can run right up along part without cutting too deep. Haven't had a mill crash in long time and don't want one anytime soon. At least this operation will not be 20min set up 1 min cutting time. And one of those parts that now I need to make more parts to cut the part!!!!

Welcome to the world of machining son

Well,,,, I guess I like digging more than driving but that's the reason for such a large haul truck and small excavator to load. Also it's what I got . When planning this type of truck I wanted to make the biggest (largest load capacity) I could. In the beginning I had excavator height to limit the build or it would have been a 797. The dumptruck I have is loaded with three scoops. That's too quick for me . For my enjoyment I like the idea of taking a while to load and short amount of time to haul/dump.
As far as wheels, I'm done with one side for back axle rims, well almost have to cut some more. And the duel hub needs cut to accept rims. They are going to bolt onto wheel hub and when they do they will be clamping the tire. Hopefully no wheel/rim spinning. If it does happen I can mill of some material on inside of two piece rims. I made them a little thick for that reason. (I don't know what to expect with that silicone rubber in the long run. Hopefully by weekend I'll have one side done to show. Or by weekend I'll have more spare future build parts

This may give you a better idea of what I'm trying to do. The bolt flange allows the rim to rotate past mounting ears then rotated a bit to line up bolt holes.
