Here is the engine folding crane I bought:...

I have a couple of question. When using the engine folding crane (the one where the legs unfold at the front) to lift the IH mill on to a bench, what prevents the crane and mill from rolling out of...

All those rules is too confusing for a newbie like myself. How about this rule. Use maximum coolant when cutting anything metal (aluminum, steel, cast iron, and etc.). Will I be OK with this...

yantra3d,

Nice stand. What is the thickness of the sheet metal for the stand where grooves were cut and ends were flipped upwards? Also, what is the size and thickness of the frame of the stand?...

I am considering getting the CNC Industrial Hobbies benchtop milling machine. The problem I have now is that I live in an apartment in the San Jose, CA area. I will have to move into a house...

Thanks for the information. I do have the Digital Machinist issues with part 1 & 2 of the CNC conversion that was sent to me for free. I ended up subscribing to this magazine a few weeks ago. I...

I have a question about the rail rods that the bearings slide on. Did you purchase them with the threaded holes on the rail rods or did you drill them in yourself? I am trying to find an easy way...

Hello,

I am thinking about buying a full size vertical mill (not a benchtop size) from grizzly.com. Once I get this mill, I would like to convert it into a CNC mill. Are there kits and/or plans...

I am using a cordless drill (415 lb-in torque) with the tap in the drill chuck. This works ok except for one problem. When the tap becomes difficult to turn, the trill chuck will spin while the tap...

Thanks for the ebay link.

Are there other sources for t-Slot type tables?

Where can I buy the T-Slot aluminum extrusion that can be used to build the CNC work table where your raw material to be milled can be clamped down? I am not interested in using the regular aluminum...

I need to make an exact 1" dia. hole in 0.5 thick aluminum so that I can mount a flanged sleeve bearing in this hole. I was told that a regular drill bit does not make exact size holes and the...

I need the name of this part so I can order one. It is the part that attaches the acme screw to the stepper motor. If your stepper motor uses a 1/4" dia. end and acme screw is 1/2", then this part...

I am trying to understand how a linear actuator works. My application needs a fast moving actuator with very little load. The idea is to use the least amount of hardware and work as possible. The...

This is about Automatic Tool Changers used in R8 spindles. What is this particular part called (fingers)? It is the "fingers" or claws that grab the retention knob and is attached to the end of the...

Has anyone tried to resolve the ballscrew whipping by fixing the ballscrew and rotating only the ball nut? How does one design something like this?

I like the bearings from www.yi-tong.com over the THK or Hiwin bearings since they are much cheaper. The W series says you can use a inside or outside of a 90 deg angle as a rail. Can someone...

I designed these skate bearings in CAD. I need some aluminum 0.5" plates machined on an accurate CNC mill. The plate sizes (length & width) are exact measurements and need to be CNC milled to size....

I used SolidWorks to create this bearing design. It uses skate bearings that are Abec-7, 22mm OD x 8mm ID x 7mm wide which I purchased for cheap at ebay. The top plate of the bearing measures 8" x...

I am interested in putting together a Ballscrew wth a Fixed-Screw method. This is when the screws are fixed and do not turn while the nut will rotate. This method allows me to use 5/8" diameter at...

svenakela,
What is the web site for the INA manufacturer? Also, what is the name and web site for the chineese manufacturer the makes cheaper but similar devices that you mentioned?

The design uses belts. Belts are probably cheaper than acme screws/ball scews and accomodates long axis (e.g. 6+ feet). The question is how accurate can belts be? I understand there will be some...

<please delete this message>

I found some ABEC-7 (best accuracy) bearings that are originally for skateboards. They are about $1/each. See the web link below. I plan to use these bearings to build my own bearings & sliding...

What is the criteria when building your own CNC that must cut anything like metal/steel and you want to build everything from scratch? I am in the middle of building one using 3" x 3" x 0.25" mild...

I am looking for a program that does nesting and 2D Milling for wood and metal. I know that Pro Engineer has a sheetmetal module that does nesting. Instead of sheetmetal milling, can it do wood or...

jcc3inc,

I plan to make something like what you have in the pictures. I have some questions. The position of the bearings is depended on the hole that is drilled through the metal piece. How do...

I am considering using a Rack and Pinion instead of ballscrews. I have a few questions:

1) Where on the internet can I find Rack and Pinion parts?
2) What type of Rack and Pinion should I...

I use 3" x 3" x 0.25" mild steel square tubing to build my CNC machine. I need to make sure I protect it from rust. I will be using a 4.5" wire grinder attachment to remove the rust already on the...
