Step 2: Design

The design:
I started out measuring the original Emco steady and transferring the measures to my sketchup drawing. I wanted a 20mm wide outer ring to provide the desired stability. And all parts should fit on the stock materials I already have.
I decided to use some leftover 10*100mm material 6060 aluminum, this is a nice tensile strength  easy machinable material.
I also had some 10*10mm tool steel stock leftover. So all parts are designed to do with these materials.

I used sketchup only for the basic design. I have found that Sketchup is a very nice program for when you want to draw some thing quickly, see how it looks, make quick changes, fit parts together etc. But if you are using any wierd measures and high accuracies sketchup length snaps and leaves you with inacurate drawings no good for exporting. By wierd measures I mean figures in the 0.001mm range, it does 1.000mm just fine but 4,376 not so much.

So after finishing the design insketchup I redrew it in my CAM program
Assigned mill paths to the different operations and exported the G-code files
Very nice work, the steady is the one piece of equipment that I have never used on a lathe, all my time as a fitter was spent on stuff that was no longer than 5-6&quot; long so I just never had need to use one, also never got in much work on 4 jaw chucks either.<br> <br> &nbsp;I just got an old Compact 5 back to life once all the broken PC gubbins was removed, now i'm slowly trying to acquire the few essential bits and pieces that allow. you to start making the&nbsp;other&nbsp;bits and pieces.<br> <br> There is nothing crude about tapping the bearings on with the alu bar, my old engineering tutor often&nbsp;referred&nbsp;to hammers as the gentle persuader. &nbsp;at least you used something soft as a punch.
Thanks, I spend some time tinkering with sound suppressors on my Compact 5. Then having such a steady really comes in handy. Especially for threading somewhat longer and thicker tubes. But I used it only a hand full of times, still it's handy to have one around. <br>True true, some times some gentle persuasion is all that it needs. Although I was a bit afraid I was going to ruin my bearings with a wrong tap. <br>Thanks for your comment <br>
Really nice. Thanks for the Instructable.
