I spoke to JT about the drawbar upgrade and the bearing load, and he said they have a customer who has used the design for 3 years with no bearing issues. They use a double row high angular contact...

Kawazuki,
Yes, we are pretty spoiled over here. A drive through any middle class neighborhood and you will see homes with 2 or 3 car garages, often so filled with toys that the 2 new cars are...

If it's a 2014, it should be covered under warranty, but probably not for lightning strikes. Those units might have an internal fuse protection, and if you are going to replace it anyway, it...

You might look over on the Tormach forum- Their early machines were all Mach 3 based, but the new Path Pilot is a linux system, and there has been a lot of discussion about it.

Looks like Shopmaster has been working on their site and have added some nice videos.

Sounds like you are familiar with the subject. I can only speak from experience. Maybe try over on this forum for better answers.

Our machine had 4 pole inverter duty motors wired for STAR configuration. We did not find any significant loss of power throughout the RPM range. I have read some of the theory, but unless you are...

There are several options depending on what RPM you are looking for. You can probably get up to 5-6000 with the current setup with some slight mods, but if you want 10-20,000 speeds you will need...

Shopmaster/Shoptask has always been good at listening to customer ideas and adding them to the machines whenever practical. You might find some more pleasant surprises when your machine arrives.

The pins are threaded- I think 5MM- you can just screw a bolt in and pry up on the bolt head, or put a little spacer over the pin and use the bolt as a puller.

Looks like a nice setup- ball screws and X, Y carriage all from the same manifold. I E-mailed Shopmaster and they said its on the next container due in a few weeks. Some other upgrades in the...

@Sharpshooter90, Thanks for the new video. It seems the Late-July container shipment has been pushed back to ~Mid-September, so I'm still waiting on my machine. I've been looking over the...

Here is a video link of a simple job making delrin bushings on the mill turn. Looks like an easy setup and simple set of gang tooling- looks like they could turn out a few hundred per day easy.

Here's a link to an innovative tool- another Patriot owner has put one of these on his machine for barrel work.

Straight Shot Gunsmithing

Kinda odd way of doing it- I would have first done the z axis alignment, because after he loosens his clamps to put the shim under, he'll have to redo his original work. I would have put a parallel...

Guys, I'll jump in here with what I remember- anyone who spots an error please correct me.
Stepper motors usually run about 200 rpm max, and with microstepping that goes up to about 2000. But the...

Wow- If I did a weld like that, I sure wouldn't post it for the world to see. What machine are you working on? That looks like one of the old 90's units, not a Patriot.

I think the original point got lost early on when one poster assumed that the screws were worn. I doubt that wear is the issue on a hobby machine - it's more likely just undersized balls from the...

Here is a pretty good video on re-packing those screws.
Not sure what the sizes are, my older unit used the NOOK screws with .125" balls- these look similar in the video, but are most likely metric....

My Shopmaster runs Mach 3 on a Dell 745 computer that they supply with the machine. They clean the hard drive of all programs except Win XP and Mach 3, set the parallel port to EPP and tell you not...

Sarge,
Interesting post- there are a lot of guys like your Dad. Everyone posting on this forum is using a computer made overseas as well. However, the 3 in 1 machine cannot be accused of shipping...

Sarge,
As far as being happy with the machine, I'm on my third model, so I think that speaks for itself. I think its the best value for the money in a combo unit, and if your space limits you , then...

Rigidity is really a function of mass despite some theories to the contrary. So you have to compare the machine to others of similar weight to get an idea of where it fits. At 900 # it's heavier...

Take a look at the Shopmaster Cnc Milling Machine, Metal Lathe Mill Drill, 3 In 1 Machine. Its out of your stated budget, but your budget is not going to get you anything worth while any way. ...

Serial # doesn't mean anything- they may have started at number 2000. According to US Customs records they have imported 93 mills since 2009.

The first thing you need to check is if the tailstock barrel is travelling parallel to the ways- on those machines with the combo tailstock/ steady rest, any contamination- even paint between the...

Check out this company- they are now producing a lot of the old Shoptask upgrades including the quadra lift, but upgraded to the full bridgemill design with 5th column.

POWER TAILSTOCK

Is your error consistent? I.E. At MS1000 are you getting 1308RPM? If yes, then just adjust the pulley ratio numbers until they match.

It would take a lot to explain why this happens, but if you've ever dealt with China you will understand. It's not so much that they can't do it, but if the factory manager can promise to do it, and...

Not very likely, according to US Customs, they have only 1 shipment in 2012- 20 cartons of small lathe parts weighing 2850 KG- thats about 300# per carton- most likely a shipment of those small cnc...
