Chassis Build #7

#1 You will now need to cut a brass flat K&S #8242 - .032 1" long x 8mm wide top right of the ruler. Then cut two K&S rectangle #8264 at 8mm wide equally top left above the ruler. Then cut a 1" section of K&S 3/32" square tube at the bottom of the ruler. You will also need to cut a piece of .063 wire 68mm long not shown. Sand all the brass top sides bottom and be sure to remove all the burs and cut all the tubes clear so the steel rod will pass through easily as pictured. Do not sand the steel rod.
#2 Place the flat 8mm brass on the center section with a smear of flux on the bottom as shown and ahead of the end bell. Remove the motor housing from the area. #3 Make sure that you move the tube on the center section an equal distance front and back on the side brass tubes as shown. Now solder the 8mm brass section to the center section as shown. #4 Now put the steel rod through the 1" square tube and place on top of the center of the 8mm flat brass that you just finished soldering. After soldering, the chassis should look like picture 4. Be sure you keep the side rails tight against the motor mount. #5 Keep the tubes centered again. Now put the rectangle at each end of the .062 rod centered to the rod as shown. Put a bit of flux at each end of the rectangle and solder the two ends of each rectangle as seen in picture 6. #6 You can now remove the two rods and clean the two side pans and center section of all the excess flux with some lighter fluid and a piece of paper towel. If you have some excess solder on the brass, you can sand that away also.
