Manufacturing Steps Cut a 0.75 in. diameter piece of aluminum to a 2.50 in. length. Chuck the piece in the lathe and face the end. Machine this end to a 0.25 in. X 1.25 in. section. Sand and polish the top shaft. Remove and flip the piece, chuck the 0.25 in. end into the chuck about 0.75 in. 5 Copyright © Texas Education Agency, All rights reserved.

Manufacturing Steps, Con’t Face this end and run some clean up passes on the length of the remaining material. Cut a taper back 0.75 in. from the end. Sand and polish the top. Remove and test the spinning of the top. 6 Copyright © Texas Education Agency, All rights reserved.

Project Rubric for the Top Top: Measure each section. Write the measurement in the blanks provided. If the measurements are within tolerance, the section receives the maximum points. If the measurement is not within tolerance, the points can be from 0 and up. Add the points for a grade. 7 Section of Part DiameterLengthPoints MaxPoints Received Overall measurement 20 points 0.25 in. diameter 15 points 0.75 in. diameter 15 points Taper25 points Finish15 points Spin10 points Grade: Copyright © Texas Education Agency, All rights reserved.

Assembling the Vise Bolt the jaw faces to the two slotted jaws. Bolt the fix jaw assembly to the base using the 0.25 in. X 0.75 in. fastener. Slide the movable jaw onto the base, turn the assembly over, and install the jaw lock with the fastener. Copyright © Texas Education Agency, All rights reserved.

Assembling the Vise, Con’t Mount the front jaw onto the base with the fastener. Install the screw through the front jaw and into the movable jaw. Tighten the setscrew in the moveable jaw to hold the screw into that jaw. Test vise for ease of movement. Copyright © Texas Education Agency, All rights reserved.
