Thanks Jeff, the picture matches. Part ordered.

Hi Guys

I've just broken the lead-screw nut on the crossfeed on my 9x20 lathe. It is the same as shown on the top screw in this picture on Micro-Machine-Shop.com...

Brilliant, thanks. I'd never seen that option before.

That is one solution, but I'm not sure how to draw a spiral in that software.

With cambam it's very easy to face off round bar stock (held vertically) by using the pocket method. This produces a nice spiral from inside to outside.
But to cut down the vibration of the tool...

Yes. But only with 3mm ball-nose cutters. I had big problems with the cutter flexing sideways under the cutting forces and had to go for very shallow cuts to keep on target.
3mm 2 flute ball-nose,...

Just to let you guys know that almost 5 years on this is still working excellently. It does about a job per week, sometimes more, sometimes less. Most jobs are cutting alumimium, always cutting dry...

Thanks Ralf. For some reason I didn't get the reply notification for this. I just found the side-profile arc yesterday when I was trying to apply a slope to a side profile. I can't beleive I was...

I run solidworks but have Rhino mostly for file conversion. I have successfully used Rhino 3D DXF surfaces and arcs. But I don't do that often. Most of my machining starts as a 2D DXF.

I would run the circles first and rectangle last. It will make your work-holding much easier.

Hi Guys

I have a round bar of ~42mm mounted vertically and I need to create a 6mm radius around the corner. I would be using a ball-nose cutter of 8mm diameter.
I can set this up manually with a...

Thanks Andy, email received and it's working as it should now.

Thanks for the reply.

This is a profiling an HTD timing pulley with a 3mm end-mill, the roughing with a 0.3mm offset works perfectly, but the finishing, which is the same as the roughing, just not...

I found a utility that removes the 2mb memory access limit for 32bit applications on 64 bit win7. But now it just hangs when it gets a bit further along.

Is there any way around this? I need to...

Hi Guys

I'm having a "system.outofmemoryexception" and it's really putting a damper on my day.
It's happening when I try to generate cut-paths on a trapezoidal timing pulley. Roughing is fine,...

Thanks guys

I had to find and copy the .xml standards files from the allusers/application data directory on the xp machine to the equivalent program data/cambam directory on the win7 machine.

I'm migrating over to a new computer and need to move CAMBAM while keeping all my styles etc intact. What is the best way?

Old PC was XP pro, new is Win7-64 professional. I have about 10 days...

Has anyone measured the torsional stiffness of an oldham coupler vs lovejoy? I think the results would surprise most people.

Mhackney, you must be cutting a boat load of parts. I've lost count...

I run 270oz-in steppers on all three axis of my X2. They have no problems drilling mild steel and I have never stalled the Z axis.
Basically I can't see why people are installing 380's, there is no...

Soo busy times.

I had problems with the grease in the taper rollers getting hot and running out. Since I couldn't find a suitable seal to go under the bearing, I had a go with the SKF explorer...

I had a horrible grumbling noise in mine. I replaced the spindle and gear bearings with no improvement. It turned out to be the plastic drive gears had worn enough to sound awful.

I went for the...

I bought a Rhino license to do all the things solidworks can't do (like export 3D DXF and file conversion). But as modelling software I cannot get my head around it. It's just too different to...

Are any of those shortcomings a problem for your target market?

From where I am sitting, this is looking like a classic example of specification creep.

The drawing shows deep groove radial bearings, not angular contact.

Why are you using two bearings at the bottom of the spindle? Generally bearings installed like that just fight each other, causing friction and premature wear.

Got the bill, the polishing and anodising was basically $US50. Excellent value as far as I'm concerned. I just fitted the belt-drive last night, I've got 2,300rpm in low range and 6,000 rpm in high...

It took about a week. I don't know the cost yet, these guys invoice me end of month.

My Steele Company belt drive is back from the anodisers and looking great.:cool:

I don't see your attached file.

Sure, here's the process.
CAMBAM which I use cam import 3D DXF files, but solidworks can't export them. I'm using Rhino as file conversion in the middle.
To get the machining path on a curved...
