Made some progress on the walls over the weekend.....
This one shows Tom doing a sucky job. I meant using the vacuum.

Now while I like a gal that shows a little leg, this is going to be a lady. Preview of her in her skirt.

With a lot of help from friends and my wife the walls are well underway. For the first stage we have 4 more pieces to put up. Then they all need to be trimmed. You will notice in the pictures that we have lots of variation in the walls. That is because of all of the elevation changes in the track. The plastic was cut into oversized strips and attached to the track. When we get them all on we will go back through and trim them to size using the track surface as a guide. The plan is to guide the rotozip along the wall riding on the track surface to cut the top edge. Then use the top edge of the wall to guide the rotozip along the track to cut the bottom edge of the wall. Will it work? watch to see.
