On the clunking sound, if all your handles are tight etc. it is probably due to your settings in backlash compensation and shuttle wheel acceleration. Reduce backlash max speed to 50% and set...

On my machine, I found the Y coupler got loose after a while, so I swapped out the factory set screws with some top quality dog point units that were about 5mm longer and put a jam nut on each one-...

The ball screws are metric- very close to 5 TPI, but not exactly.

Here's a simple mod I made on my machine to make the Z axis belt tensioning a lot easier.

Looks like we both went down that same dead end road- I tried the smooth stepper because it allowed the use of newer computers and even tablets with the ethernet cable and they claimed it smoothed...

[QUOTE=bill.anderson;1912156]Yes the Patriot is a 4 axis combination Lathe & Mill with Gecko G540 and an USB SmoothStepper.

I tried the USB Smooth stepper and could never really get it working...

Yeah- it gets kinda complicated trying to do it under cnc- here is a you tube link that is interesting. Using a gear drive lathe and selecting the right threading ratio is pretty easy. With your...

I would say that making an arbor with grooves would be the simplest- you could put a hole in 1 end and bend the wire into the hole to hold it, give it a turn by hand to get started in the groove,...

I've never tried spring making- could you post a picture of your setup? It seems that if you were making an extension spring, all you would need is a round arbor of the right diameter to wind it...

As far as choosing a machine goes, you need to make that decision based on your budget and needs. the working envelope is pretty much the same as most mills in this size. The Mill turn uses the...

There is a guy on the Shopmaster forum who has done a similar conversion using his glass scales for feedback- he goes into a lot of detail...

I've been following your post, but the electronic talk is way beyond my understanding. However, my old Patriot machine could get 40 IPM with the original stepper and the 2-1 drive ratio. Switching...

There was some discussion about this, but it was on another thread about an older machine, so I thought I would put it out here for Mill Turn owners only.
The standard configuration for the Mill...

The Chinese built a copy machine like that years ago with the column mounted to the tailstock with an adjustable column so the tailstock could be moved. It was never picked up on by any of the big...

You should have called JT- My machine had one bad caster, and he sent me a full set of 4 upgraded ones with a higher load rating, bigger bearings etc. for free.

Tkamster,
I'm interested to see what you machine looks like- do you have a website?

I have been able to correspond with Shopmaster regarding this. My memory's vague, but I think correspondences did not work through the Shopmaster website but did through direct Email so they were...

Not sure if that was directed at me or just anyone. All the machines on these forums, Charter Oak, Novakon, Smithy and Tormach are essentially re-branded or slightly modified versions of Chinese...

I don't have any experience with a Sieg mill, so I can't say how rigid they are. I have used larger machines like old Bridgeports, which are quite solid. As far as the Shoptasks and Shopmasters I...

To be fair, for many people floor space is precious and working from a home garage often precludes larger machines. The old saying about having to constantly tear down setups is mostly predicated on...

I have seen the videos of the Inturn device, and it is pretty slick and appears to be well made. There may be some software integration issues with PathPilot, which has not been bug free, so keep in...

I sold these units almost as soon as the thread posted- Thanks to all who inquired and sorry you missed out.

Of course, those are rapids, on the cutting speeds that depends on the material etc. When testing I usually cut a piece of HDO, and that will cut at max with no problem.
On the Mill Turn they...

The Duality lathe was an attempt to turn the Tormach Mill into a combo machine. It was universally panned, and Tormach quickly dumped it. That is when they moved on to a separate full scale lathe...

I posted a partial answer on the other thread, but if you are in the prototyping stage, the Mill Turn is a good option. In my experience, any product design goes through numerous modifications...

I'm not sure what the issue is between you and JT, but I have been dealing with him for over 20 years and 4 different models of his machines. He has always been prompt in answering questions and...

I have an early USB version of Smooth Stepper and the latest Ethernet version as well. I fiddled with the USB version for quite a while, but could never really make it work, so I fell for the "new...

Hanermo,
You are right about increasing the overall speed of the mill, as it requires a lot of other things. However, I think the original poster was referring to the spindle speed only. The older...

EP,
The spindle has a bolt on face plate which has a machined shoulder that centers the 3 jaw chuck, which is then secured with 3 bolts. The shoulder also matches the recess in my Chinese 4 jaw...

I've made a few upgrades to my machine to improve performance. All were done without any changes to the machine frame, just swapping out components.

1. I changed the drive ratio on the X axis...
