How to make a bench stand to hold Honda CB750 engine out of steel

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.

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. 

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.

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.

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.

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.

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.

Powder Coating

After cleaning up the pieces with some Simple Green and a wire brush, I powder coated them with Ink Black.
