By completing this guide you will gain an understanding of how to use the tail stock on a lathe and also have a sweet new rook to add to your chess piece.
Step 1 — Trim the Stock
- Use the band saw to trim a 1 in round of aluminum to 3 in long.
Step 2 — Chuck the Stock
- Insert the stock in the chuck. Ensure at least 2 inches of stock are protruding.
- Clamp the stock as tightly as you can
- Do not take your hand off the key while it is in the chuck. Ensure you close the chuck cover.
Step 3 — Touch off the Tool
- Put a Right-Hand Turning tool on the tool post and face the part to zero the Z axis
- Turn a section and set the tool diameter in the DRO.
Step 4 — Turn the Rook Top
- Turn a half inch section of the bar to .6 in OD
Step 5 — Drill the Rook Top
- Insert a center drill in the tail stock.
- Create a spot to center the next drilling operation
- Drill .5 inches deep with a #42 drill bit
- Drill .3 inches deep with a half inch end mill.
- Install a spring center in the tail stock.
- Tap the hole. Be careful not to bottom out the tap
Step 6 — Part off Rook Topper
- Switch to the parting off tool
- Using lots of brush on lubricant while quickly parting off the top piece.
- Do not move the Z axis while parting off the top piece
- Do not change the coordinate system while parting off.
Step 7 — Turn Rook Bottom
- Put the right hand turning tool on the tool post.
- Face the part and set the Z axis
- Turn the entire part to .95 OD.
- Turn a .55 in long section to .4in OD.
- Turn a .2 in long section to .138 in OD
Step 8 — Turn Rook Radius
- Start with the RH turn tool at X = .4 Z = +1.0 (the tool is 1 inch away from the face of the part)
- Use the ‘Do-One’ Menu to set up a Radius of 1.49in
- Move the tool in until it is at Z=-1.25 in
- Move the tool back out , and reduce the Z by 30 thou. Repeat from step 1 until at a Z of -.55 in
Step 9 — Turn Rook Base
- Using the Do-One menu turn the fillet on the top surface of the rook base.
- See if you can figure out where to start the tool!
- If you get stumped, try starting at the right diameter and approaching on the Z-axis while repeating do-one fillets
Step 10 — Finish Rook Base
- Using the Parting Tool, separate the piece
- Flip the part around in the chuck
- Do the back filet on the base.
Step 11 — Finish the Rook
- Screw the two together! Now you have a Rook!
