Intro: CB750 Engine Stand

How to make a bench stand to hold Honda CB750 engine out of steel
Step 1: Raw Steel
Procured a sheet of 10 gauge steel from my local Metal Supermarket. I used a buddys retail purchased stand to draw out the pattern. But as long as you measure out the distance between the bolt holes and raise them up a bit so the bottom of the motor will clear your work surface, you can vary from this design.
Step 2: Saw Off the Feet
I used the horizontal band saw to saw off a strip from the raw sheet and then cut that into four even pieces. These will become my feet for the stands.
Step 3: Finishing the Feet
I then used the grinding wheel to round off the corners of the four feet so they would not have sharp edges. Also, ground down the burrs from cutting them.
Step 4: Cutting Out the Sides.
The sides had curves in the pattern, so I used the drill press to make some relief holes at the bend, so that when the saw blade got to that section, it wouldnt be stressed and I could make the turn to finish the cut. I cut these pieces out using the vertical band saw.
Step 5: Still Cutting Out the Sides
I made some more straight relief cuts at the bends in the pattern so I could cut more material out with the vertical band saw.
Step 6: Finishing the Sides
After I got as close as i could with the saw, I needed to grind down my edges. The shape of the piece made it hard to use the grinding wheel on the curved sections, so I used a hand tool with a grinding stone attachment.
Step 7: Welding the Feet On
I used the TIG welder to weld the feet to the sides. Took a little messing around to get the right setting, but finally achieved the best results with 150amps and 1/8 filler rod. I ground the fillet edge on an angle, so that the filler could set into the groove.
Step 8: Powder Coating
After cleaning up the pieces with some Simple Green and a wire brush, I powder coated them with Ink Black.
