Sherline CNC 5400 Mill | eBay

I bought a set of this stuff to lap the ways on my IH Mill, years ago. I bought the mill used off ebay, and when it came in , I noticed it had already been lapped by the previous owner, so i never...

hmmm. I hadnt considered oldham type couplers. I think I will try that.

Thanks,
Devin

Mcmaster.com has a way better selection but I couldnt find anything better in price. After looking some more, I found the couplers for around 12.00 a piece at Anaheim, the lowest price I could find...

I found some helical couplings at anaheim automation for a decent price.

CPL-HC - Integral Clamp Coupling

I have already machined the rigid coupler as mentioned by Matt and was planning on using it to aid in alignment as also mentioned.

However, Phil's idea of machining the bores once assembled makes...

guys,
I have just finished making the parts for my x-axis stepper mount and before I snug everything up, I wanted to see if anyone had any good ideas on how to make sure the stepper was lined up...

Mach3 has a wizard for probing. The info is saved as a point cloud. this cloud is imported into a cad program to be cleaned up and then a cam program to generate your gcode to cut the part.

The probe worked but not without flaws. The three prongs that rest on the ball bearings would get stuck ever so slightly and give less than consistent results. I knew it was a flaw in the way I cut...

the link in my post works for me, but here is the addy minusto cut n paste in your browser

Ray, I fixed the link.

Ray,
I am using them on my IH conversion. They can be preloaded quite easily and seem to be working well. Here is a good link on a way to set the preload when using non-matching AC bearings....

Found a specifically for the 540 here:

You posted about being mature, laid back and letting things slide and yet you did none of those things. I found it ironic and humorous so I replied as such. Additionally both Jalessi and I actually...

Gee, sounds like your doing the exact same thing in your post. Seriously?

maybe a foundry is in order. lol

wow!

got it. Thanks for the files. I was just starting on these myself. You saved me some time for sure.

Can't find the link at the moment but I saw a page where a guy used PVC pipe for his drum. Cheap and light. Just a thought.

Outstanding thread! Thank you for sharing WidgetMaster.

I scavenged the rollers, motor, and controller,power supply,bearings, belt etc. from a treadmill. I wont be starting for some time due to other projects. I'm building one of these,...

No problem with the confrontation Jeff, but this thread is about an RF45 clone/type mill and so is my post. If someone makes the rather large jump to thinking that my post applies to all mills...

I only refer to an rf45 in my post. Not sure why you mention the other styles, I guess I missed something in the post, but agree with you that a different style mill would definately need a brake.

I just had this same question as I am putting precision ground ballscrews on my IH mill. I was advised it wouldnt need a brake. I tested it last night and it definately wont need a brake unless your...

Excellent! Thanks Ray.

Thanks for the post Ray. I am looking at one of these for my IH and thought it too good a deal for 150.00. Sounds like its just what I'm looking for. Where is the macropump driver?

Thanks,
Devin
