More progress, I tacked the plenum together ready for final welding but due to it being 1/2" plate my 200amp machine was not gonna do the job without a lot of preheat so it was off to see Mr Miller Dynasty
Got it all welded together late in the evening eventually, then had to drink numerous cups of tea while it cooled down
Thanks Gary
One of the mounting lugs on the intake had been damaged at some point so this was built up with weld and reshaped.
The bottom plate thats bolts to the inlet bowed by about 20 thou over the length so it got a small fly cut on the mill. If you have never seen flycutting i've added a short video below.
I mocked it up to have a look and discovered the front plate is a little shy in 2 corners so will have to make up a couple of bits and welded them in.
Next up was the snout drive shaft, its 1.250" steel bar turned done to be welded in to the hub at the blower end, the other end I have to broach a keyway into, made up the pulley flange. the shaft has been left long at the moment so I have something to hold on, I will shorten once its all mocked up on the motor.
I was a little concerned about the mounting bolts on the intake not being very far apart, probably be fine but just to be sure I added a pair of braces, they have to be welded to the intake yet, they bolt to the 1/2" blower plate with 2 x 1/4" bolts.
Here it is mocked up in place ready to measure for the snout length.
