Ok, maybe it was Cnc4pc that fulfilled my order, which could be why I was irritated since I purposely chose not to do business with them. I honestly don't remember. I also did receive what seemed...

I'm in the US and I ordered from the cncdrive.com site. I did not want to deal with CNC4PC, and Automation Technologies didn't list one of the parts I needed, so I ordered direct. If I recall...

Mine was an older machine (TriPower) with the gearboxes and manual controls. It was a factory CNC, but the CNC stuff was just sort of cobbled on in those days. It was all worn out and it wasn't a...

Check your motor wiring. The motors on my 2007 were wired bipolar series. Changing them to bipolar parallel provides more torque at high speeds. There is no drawback other than higher current draw....

McMaster Carr has them in socket head set screw type or with square heads. M8x1.25.

I would start by removing the pointed gib screws and tossing them in the trash. Replace them with dog point screws and machine flats on the gibs for the screws to push on. The pointed screws can...

If you want me to be fair I should probably also say that I own a Bridgeport mill and a 14x60 South Bend lathe, which together cost about half of what I paid for the used Shopmaster. They are my...

Yes, though I have been out of the Fiero business for several years.

I can understand the buyer's remorse, I had the same feeling after buying a used one at a fraction of the cost. I bought mine at auction without prior inspection, my evaluation was based on a few...

You'd be way ahead to just buy a used commercial liquid handling system and retrofit whatever control software you want to use. There are a bunch of them on Ebay right now for under $200. For that...

I bought some screws from Chai of linearmotionbearings2008, two 1605 screws with ends machined, "anti-backlash" nuts, and end support bearings/blocks. They were cheap enough that it won't break me if...

A picture of the new 2015 Mill-Turn machine is up on the Shopmaster site. Looks like they've made some significant changes. It has a full length gantry for the mill spindle supported by six 1"...

Victor, The Nook and Thomson screws that were used on these machines have a gothic arch profile, so that doesn't apply to those. I'm not sure about the newer machines.

CG, I wouldn't use wd40 to...

I'm can't pinpoint the exact reason why, but you come across as an *******. I'm sure you're a really nice guy in person. :rolleyes:




I don't think anyone would be surprised that larger screws...

McMaster Carr

5966K16 $31.23

I haven't purchased these and McMaster doesn't list manufacturers, but I found several posts on this forum and others saying they are Thomson. They...

Toolsupply on Ebay has them in .0001" increments.
ToolSupply ballscrew balls

They are $45-55 each after shipping, and you also need to consider the extra work to fit them. Those are plain screws with no end machining. That's a whole lot more work than replacing balls. My...

On the Tri-Power the ball nut has external threads for mounting, it screws into an adapter that fits into the mounting block. I think you could take a second nut and screw it in from the opposite...

I didn't realize it until I started looking at part numbers, these screws are left hand. The Thomson part number for the nut is 8106-448-026, and the matching screw is 190-9099 sold per foot. Wiper...

My x axis screw wobbles a bit, it either got bent or was not welded straight. The nut was making crunching sounds from all the chips that got into it. Due to these factors I believe I'll be replacing...

ShopMaster Tri-Power Eldorado Bridgemill. It's the model just before the Patriot.

I just picked up a used Tri-Power with CNC and ball screws. It's got .011" backlash on the X axis, .010" between the screw/nut and .001" at the thrust bearings. I tore right into it, found some...

I don't think this is a case of wear at all, I think it's pretty common for these inexpensive screws to have that amount of backlash when new, isn't it? I think the problem is exactly what CG found,...

Metric screws do not necessarily use metric balls. I repacked some Misumi 8mm screws that use .0625" balls (1.5875mm) per manufacturer's specs. In any case I think I'd want to measure the existing...

If you're just doing a few parts here and there, blasting is the way to go. You can vary the pressure and media to suit the job, and give more attention to areas that need it. Tumbling is slow and...

I just did my first home anodizing job about a month ago. It's really not that difficult, and not too expensive to do small parts. There are plenty of online guides, lots to learn before getting...

There are cracked versions out there that work indefinately, and if that's what you want you don't have to pay anything for it, you just need to know where to find it.
You can actually learn how to...

None at all.

The single best improvement I've made to my machine was replacing the Keling drives with a g540. I get less noise, less motor heating, smoother motion, more torque and more speed with less current. I...

That's some nice looking hardware you've got. I don't think you will want to use the planetary reduction on the Z axis. You may need to make your own adapter or modify the plate to mount the motor...
