Been looking around for a source of super thin wall sq. tubes with out much luck for small quantities. I'm talking 1/32 or less wall on 1 1/4" tube.

I have some changes to my quote.

This is not a high precision part. When in use, all sides will be touching foam padding, or fabric, so I just need the corners rounded as to not tear into the...

6061 Aluminun Bar
0.75" x 0.125" X 14"
Bar may be extruded with rounded corners on sides, or not, the side rounding is preferred, but not important.
Ends rounded at 0.045 radius on all 4 edges. No...

I need quotes for 1, 50, and 250 of each part.

Bearing mount is 6061 Aluminum

Housing is ABS

Tolerance standard

Finish standard

I've made a few of them like this, they turned out ok, but I didn't do a finishing pass, used a 4 flute 1/4 inch. I used T-slot clamps to hold the parallel on top the 123's.

I raised a parallel between 2, 123 blocks, and with long 10-24 screw, bolted it through the center hole, with a piece of scrap under the parallel to use as a washer, because the parallel's hole is...

I have a grizzly mini mill, which had a stuck arbor, which I had to press out, but I banged on it hard with a hammer before, so my bearing might be screwed, or my spindle bent. Anyways now I have 2...

I'm using a CNC mill to make the rotor.

thanks for the help. Now how would you make that round into a pump/turbine rotor, with a base of 0.070", as seen in the attachment.

I need to make a precision flywheel with OD 1.9" ID 0.25" x 0.375"

I've made one, but my arbor broke as I took it apart. First using a 2" round I turned, faced, and drilled, bored the center...

I want to be within 2 thou over 4 inches

here's what I did, I cut the vise screw to get one of the sides off my self centering vise, and put a 1 2 3 block on there. 2 precise sides should be enough, if I'm not mistaken.

I'm having trouble with facing all sides perfect, because both of my mill vises arn't perfect. Are the precision mill vises, or the toolmakers vises going to be any better?

I put the bigger balls on today, and got zero backlash in the middle of the x axis, and up to 2 thou at another section. I noticed that there's more stiffness as you put more balls in. I put 63 balls...

I got almost as much backlash as with the stock screws, and the backlash varies, as the nut travels down the screw. I don't know if it varied with the stock because I never checked it.

I have...

I have G0602 and the MT3 drill chuck does slip in the tailstock some. My drill bits keep going dull real fast too, even my cobalt one. I am using a center drill and have no wobble when the hole...

so I had to take the pully off and use a pipe wrench on the spindle, with a towel around the spindle.

My chuck is stuck on, but those spanner nuts turn off the spindle when I grip them with the pipe wrench.

I sent it to a shop to get turned, but their tools can't handle it. Does hoss say Diamond CCET inserts here? Ballscrew Turning Z Axis Part 1 - YouTube

I'm wondering if anyone knows the best way to fix this. I have to push down on the mill head to make the z axis slide down to where it should be, because there's a small gap between the Mill z axis...

The G codes looks ok as far a I can tell. Here's the g code for the rectangle witch also has the offset finish problem.

We haven't solved it yet, but it only happened when I put a Z feedrate of 44in/min in the cam program. When I leave it the default 1.25in/min it doesn't happen. I'm using a new Post Processor that...

The post is MACH_3 and it's new. Now that I know that F = feedrate, should I just put a feedrate there?

I have a complex part with a lot of arcs meeting other arcs, and I'm getting this error

There's a thread somewhere on here about McMaster carr suppliers in Canada

TSE stores, Mcmaster car doesn't ship to Canada, but small parts.com does. I use small parts a lot and get 2 day shipping free.

I have Cadstd, mach3 demo, and Dolphine demo.

I have archs around a circle in Dolphine Cad, but when I try to rotate them around the centre point the degrees of rotation are way off what I tpye...

I'd like to know the ball park cost in time, and/or money for making a simple wrench.

For example a typical 14 piece set weighs 2.6lbs, and sells for $22. The cost per wrench is $1.57 and the lbs...

well today I plunge milled without the x, y locks on and the table vidrated, that will make my endmill dull very fast won't it? Better to get some ballscrews I guess, but which are good enough not...
