With all the discussion on silos................
One member years ago had made grain silos out of PCV pipe. He had gone to one of the local grain elevators and did some drawing and talked to some people there. When he put them on the layout, it looked like it was a Lionel structure on an HO layout.
While true in size of the local elevators in New Orleans along the Mississippi, it was just overwhelming, However they do make a nice wall lining at the stadging yard.
I have been experimenting on diffrerent items for the plastic plant but was never happy with my experiments and I wasn't going to pay $85 for the only Walthers plastic pellet transfer facility I could find on EBay.
I tried cutting down shipping tubes of differing sizes, industrial paper towel rolls etc. still, I wasn't happy and refused to use any of them.
Last week, as we were getting ready for the Friday night football game ( I'm a high school band director ), the drum major asked if we were taking the plumes to the game. ( plumes are the feathers that stick into the top of a shako ).
Bam..............I went into the uniform room where I had stored some new plume "tubes" and there were the silos I was looking for. I had ordered 24 replacement tubes for tubes that were abused etc. I grabbed5 and took them to the club and they are pretty close to the right size I wanted for the plastic plant. Taking proper time to cover them with a grey or white contact paper, you can avoid ridges in the cardboard showing through. Once you add weathering they will look pretty damn good.
Plume tubes are a heavy cardboard tube and come in different sizes for a small cost. I'm sure the rivet counters will find fault, but if you need to do a quanity of silos, the price can't be beat. If it can, tell me where.
Here is a listing from just one band equipment website:
