Wow, this is a huge build.

Do you have any estimates of what the total weight will be?

480 RPM is S L O W. Real slow. The only time RPM would be optimal is with a 4"+ diameter face-mill. What...

All putters so far have been free machining brass. I think it could cut steel, but the depth of cut and feed rate would have to be a lot less.

Thanks Lee.

Thankfully, the Sherline spindle has worked out really well. The bigger case of the "industrial" version coupled with rock solid mounting (in a .05" deep close fitting slot, held by 6...

Sorry, double post.

Oh, here is the finished putter.

Thanks veteq!

Yep, all linear components were bought off ebay. I think the ballscrews averaged about $120 each and the rails $100 a pair. So about $660 plus shipping, duty, etc... I guess about...

Stage 3 vid is up. This is at 1" width of cut, .05" depth of cut, 15 IPM.

<object width="660" height="405"><param name="movie"...

hmmm, never seen those before. Approx how many did you guys make?

On another note, I found the power limit of the spindle motor tonight. No damage done to the machine and there was still a lot...

Thanks judleroy. Yep, they are custom to spec and look.

Digits: I'm running a 3/8", 3fl high helix Sowa carbide at 5,000RPM, 30 IPM, .05" DOC.

The part is a putter.

The motor/speed control is one of these:...

Watch on Youtube for the 720p version.

In terms of alignment, the Z rails were aligned two ways. The first was to make sure they were going straight up relative to the base block from side to side. This was done when the rails were...

I'll double check all mechanical connections (ball-screw mounts, bearing pre-load, couplers, etc...). But everything was lock-tited and torqued and there is no play on all three axis just trying to...

Sure, steel and even stainless milling would be possible. The depths of cut and feed rates would have to be pretty conservative though. I don't think it would have much problem with leaded steel or...

OK, the dominoes are all done. They are 1.75" by .875" by .25" thick. The finish is a bead blast with basic black paint-fill.

Cool idea. What do you have in mind for the spindle?

I looked at granite for a while (granite surface plate base) but reading up on drilling granite, making and installing inserts, etc... scared...

Yes, logically you would think it would be a simple conversion. I found the calculated values to be out a bit in actual machining and adjusted accordingly. And before anyone, asks, yes the axis were...

Thank you very much Speeds.

The Glacern truly is a fantastic vise. Every bit as good as a Kurt, maybe better.

Thanks!

As noted above backlash is excellent but I have to get steps per inch dialed in perfect to give a concrete number.

I'll give you a total cost in the next couple days.

Serge

Oh it is! When facing off the dominoes I was restricted to cutting in one direction to avoid blasting chips onto my bed. Hopefully in the next couple weeks...

Yes it's really in my bedroom.

In terms of mechanical repeatability it's excellent, all 3 axis have only .0001" of backlash due to the ground screws (measured by jogging one way then the other...

Thanks Jeff,

Yes. I'm making a standard set of 28 for a friends wife.

I'm facing of the other end right now. Next up is rounding the edges with a 1/32" carbide radius mill. Then engraving with...

Eeeek! They might discount the bigger pieces, who knows. Anyways, I think the base block is wide enough for the application. I'll run out of horsepower before any kind of flexing/deflection happens.

Sorry guys for not responding sooner.

Hi asuratman,
Do you mean the motor? The motor is a 1/2 horsepower 1700 RPM DC motor with a simple load compensating speed control (knob) type system similar...

Update: The Sherline mode fix has worked very well. No missed steps!

I've done stage one on a set of dominoes. The finished dimensions will be 1.75" by .875" by .25". A 2" by .5" billet of...

Henrik,

I sent the control back, and assume something was done to check/fix that drive. I was very clear in the emails about what was going wrong.

The computer was bought brand new. It may have...

Thanks for the info Bob.

I wanted to do it separately so the column could be removed later. The machine will have to be torn down to be moved sooner or later.

The JB is in the mild steel range...

Hi Henrik,

Thank you very much!

I'll try to explain getting the ends perpendicular a bit better.
