That is if that's the new toy.

Haha, 4 stroke MX quieter. Good one.... I'm no longer an environmentalcase so my 4 stroke is going away and will be replaced by a 2 smoker! Dear Santa, I have been so good this year

[TRUCKMAKER]

So does that mean you bought that Hayes that you and the wife were driving around?

What ?? you didn't say how many wheels it had!

[Cooper]

Reg is getting even bigger on the scale toys!!! Lol!!!


Got a little more done on the axle. A lot of turning time on axle parts. I found a way to bolt them together rather than needing to weld.




Needed to make the parts beefy,, I think I'm accomplishing that. The inner parts of axles still need a radius turned. Saving that till I get to frame parts to find exacts.

And all the tires done

[sparkycuda]

So tires ended up being about 2-1/2" X 9"? That's a bunch of rubber! Really nice job with the casting and using 3D printing for the pattern. Amazing how all the new technology is making more builds possible with really great detail.

Haha, no Hayes truck for us although my wife wants one. I think the only way you could get that one from the owner is by buying it from his estate.lol It has a good home now and will be well taken care of until he's gone. Hopefully after that who ever ends up with it will respect the old girl and not turn it into scrap. He did show where the keys are though...

Rub a Dub! Great job on the tires! I am so impressed with how well they turned out. You continue to be my hero...

awww thats nice the aluminator is paying captain silicone a compliment LOL
tires look great nice and heavy

Bahahaha!!!!!!!!!!!!!

Coop like em heavy and soft in the rear...

[DADSGARAGE]

Everything looks great so far....like the size of this build !!!
What is the size of the tires??? Two tires have a dull appearance did you sand them to remove the shine?? If so would lightly bead blasting them be an easier way to remove the shine..

[Cooper]

They (shiney ones) are recently made and still have some releas agent on them. The dull ones are older and more true to what they will finally look like.

[DADSGARAGE]

Ok got it....hey how big are the tires?

[Cooper]

Tire size = big!!


Lol!! Almost 2 1/2" wide at widest point and just shy of 8 1/2 tall. Had some shrinkage , lol!!

And time for an animal torture pic, I just had to place the "bird" feeder next to window right after I moved the plant stand with the cat bed in it!! Lol!!


I was out in garage and kept hearing a banging, cat chirping,,,, walked right up to the both of them and like I wasn't even there!! He was crying really weird and shaking.

Mission accomplished for him biteing me at 4 in morning!!!

[TRUCKMAKER]

Maybe he's just missing Mr nutter!

Tires are insane! This will be one great build when your done.

[DADSGARAGE]

Tire size does = big, those big tires will really add to the look of that truck when it is finished!! Keep up with the great work, always looking forward to seeing the new pics of this truck build......

Ok not looking forward to this operation. This may be one of the more difficult set ups and operations I have done. I don't have a centering chuck for this rotary table and even if I did I don't have the clearance. But the angles being cut will be parallel with table travel once moved off center. This is to allow the inner rims to be slid onto wheel hub then rotated for bolting two halves of wheel rim to the body of hub. Or should I have said like the 1:1 machines . Ugg guess it's got to be done .

[modelman]

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
