Last Saturday I picked up a load of scrap someone had left in the woods behind our house (car hood, old stove, other scrap iron). I had today off for President’s day so I hauled it out to C & C Metals in Marshfield and traded it for a 4 X 8 sheet of 22 gage steel. While I was there I also picked up 10 feet of one eighth by 2” X 3” steel tube to make a 52”+ guide for my table saw fence. When all was said and done it cost me $26 plus the scrap.
I have a good friend (Terry Hefield) out a JAARS in Waxhaw who is an aircraft engineer. They have lots of tools at JAARS including a 48” slip roll and power shear. The first step was to lay out the cone from the Bill Prentz website. With Terry’s help the lay out was a snap.
A couple of cuts on the shears and the two straight sides are cut. Then a few minutes with the tin snips and the cone was cut out.
Now several passes through the slip roll putting a little more curve on each time.
Tape it up with a little duct tape and you can see that the Bill Prentz dimensions and our layout were pretty close to right on.
I picked up some one eight inch pop rivets on the way home from JARRS and I expect to finish the assembly of the cone nights this week.
I am ordering a 15 ½ impeller from Grizzly for $80 and I have a 3 HP 182 Frame motor that should provide plenty of pull through the cyclone when I finish the other parts.
