Attached is a parts list for the skid-bulk bag feed, both in this post as well as an easier to read xls format attachment.
The parts for the skid is per skid. If you want an entire 4 ton truckload of coal, you would want to build 5 skids. This would allow you to leave one on the auger box still feeding the boiler while the others were being filled.
Again, the bags are 35 in x 35 in x 51 in high, full open top with skirt and either a spout bottom or no opening bottom. You are going to cut off the bottom spout anyway.
The list is for pressure treated for all boards that come in contact with the wet coal (or you could do all PT). I would use the 2 in x 8 in PT for center cross supports that the two angle irons for the slide gates are screwed into, and deck the rest of the cross supports with the 4 2 in x 4 in.
Have Home Depot cut the plywood to size on their panel saw. It's free and saves you time. Have the steel supplier cut the plate steel to size as well.
Again, for assembly details refer to the beginning of the thread under pictures with descriptions. When you get into flickr, scroll down to see text descriptions below the pictures. Again, the flickr pictures are of the 1st skid assembly. The newer skids have the double side rail supports with laminated plywood in between, magic slider gate supports and a larger rectangular hole for the coal.
The parts list includes brackets to make the "temporary" auger tube support. You don't have to make this, as the auger box will hold up the end of the auger pipe. However, it is nice to keep the auger tube from moving should you accidently oversize your auger box hole. The end of the auger screw tip is roughly 4" off the floor.
Anyone interested in seeing our setup first hand can contact me.
