|1. See hard lumps around edges|
A few months ago I started to get hard (very hard) and dry (very dry) lumps in with my pugged clay. I could ignore these pieces while throwing but they would end up as sharp bits on the bottom of pots or as dimples on the sides of pots. I could remove them while throwing and then fill in the hole left, but this would invariably throw my pot off center, and who wants to be doing that anyway?

1. Turn on the pugmill and let it run until it has pushed out all the clay that it will. Add 1 pint of water when running the last amount of clay to help lubricate the barrel and make removal easier.
2. Switch the pugmill off and unplug it.
3. Unbolt the nozzle end. Run a wire between the nozzle and the barrel. Remove the nozzle end and clean. In the picture (1) you can see the hard lumps on the outer edges of the clay, especially at the bottom.
4. Use pliers to release the spring from the rod in the vacuum chamber.

7. Scrape blades and shaft.
Of course, you're going to make a mess, especially when you remove the barrel. Be prepared for this. I wasn't and got splatter all over everything (2)
The best way found to remove the gunk from the barrel and nozzle was with a power washer (4). Once you've got it as clean as it's going to get, work backwards and put the thing together again. At this point you're going to wish that you had kept track of the screws as you were taking them off!
