I use a jackshaft on most all augers. Belt drive to motor, roller chain to auger. 2 bearings, a piece of shaft, a couple sprockets. If you want 200 rpm from 1800, 9:1 reduction. 3:1 from motor to shaft, 3:1 from shaft to auger. Way cheaper than big pulley. Smaller and easier to fit that a big pulley.

As to making the jackshaft, a couple pieces of angle iron and pillow block bearings. Or a couple pieces of flat steel, make holes for shaft and flange bearings. Either cast flanges or pressed steel.

On picture 1508, the red motor mount piece has 2 holes close to bottom. Have 2 pieces of angle iron, maybe 3/16x2, long enough to bolt to the existing holes and stick out to side a foot or so. Mount pillow block bearings to angle pieces. Use shaft same size as auger to use present pulley. Small sprocket on jackshaft. Use a quick detach hub sprocket on auger so if you want faster or slower, easy to change. Do good measuring and I think you can make that with no drilling or welding up there. Hopeful one trip up would assemble the thing. Probably not in real world.
