Hi Tim, Jim, Yeah, like the 7BA carbon steal tap (from England) I just broke! And I was being nice to it! I'm milling the cylinder for a Stuart steam engine. I decided to also mill a "practice"

What all would have to happen to allow a CNC machine to be based on a polar coordinate system rather than a rectangular one. The big benefit to me would be that the single most expensive component of

I am using one of these and like it. It is mounted up at head height so there are virtually no hot chips getting to it. It is a little funny to type on and I would not want to use it on a system that

ditto ! I did that to my old, origional drill press. I used brass screws with wingnuts to let me lock in the spindle. I tried milling with a cross slide vice. I was able to take cuts as deep as

Steer clear of these keyboards. They are made of a very thin membrane and just one hot chip can burn thru them. Also they are very wobbly when typing. It's like trying to have sex standing up on a

Radio Shack has a flexible spill-proof keyboard (you can even roll it up) for about $35.00. Mount it on a panel with double-sided tape and you're set. Regards, JJ Be Kind, Be Careful, Be

Yeah, somehow the accel rate got misconfigured and I had to redo motor tuning. Deceleration on the Y axis was a little lower than the X and Y couldnt keep up.Hence the odd rapid Z safe move to the

Ah-ha and a couple of others have plug and play units. Building your own is not that hard. I could break out my cnc router plans and give you all the information that you would need to build your

Does anyone manufacture a pre-wired drive unit with geckodrives, power supply, parallel plug etc ? I'd like to be able to just plug in the parallel cable and hook up the motors without a lot of

I pulled out my quill, drilled and tapped two 10-24 holes pointing toward the quill, one from the front, one from the side. Inserted two brass screws with nuts to lock them down, and reduced the play
