making a machine

[pyroracing85]

Where do I start? I want to make a machine that cuts tires. Here are some pictures of what other people have one

please help on where I start and ideas

Well you need a shaft to spin the tire and a head mounted on maybe to 1" dia rods, that will allow the head to move left to right. Than another pair of rods to allow the cutting bit to move in and out of the work. It's really not a complicated machine. I would first start with the mounting shaft for the tire, and draw a frame to support that. If you can give some specific info in size and tire and what type of motor you want to use to spin it this will help get this started.

I did this in less than a min, but it gives you a idea-

I see what you mean. When I get a change I will take measurements. Should I use the same motor as he uses on his? Also. How could I include a micrometer on the feed on this machine kind of like a lathe would have on the cross feed

[pyroracing85]

oh and another thing the machine follows this templates of the contour of the tire. That is how you get the correct in feed everytime. Kind of like a manual cnc machine

You can make this thing CNC driven and control it via software.

really wow that would be awesome. I would like to keep the cost of the total machine below 2500-3000 though. maybe a little more if it is cnc.

but the way the machine works is it has templates that create the same cut every time. You change the templates when you have a different size tire in the machine. I could easily machine the bolt pattern that goes onto the rim and I was thinking of having threads on the I.D.. and just having a fixture that screws in the I.D. threads inside of putting on the lug nuts.

UH? 2500.00 wow, how big is this machine? It should cost under 500.00 complete with everything.

no way seriously? cause the guy I know sells this machine for 4700 5200 with some options he has. So you think he is profitting at least 4200 a machine

WOW what a rip off

Well not really when you consider the cost of machining, for the do it yourself is almost always 1/3 the price.

I know what you mean. You would have to calcuate the time it takes for machining and the welding of some areas and the assembly.

[pyroracing85]

but on the machine. Should I start to machine the chuck (if that is what you wnat to call it). The part that goes into the wheel and hooks on the bolt pattern

[pyroracing85]

so where should I start?
