Our on-going pug mill saga

Over the past couple of weeks, we have been making pots, working towards the June Long Weekend ‘Pop-Up’ Open Studio Weekend.

I have finished building work for a while. I need to be making pots, no more work on the house until later in the year. I still need to fireproof the facia and eves of the roof against ember attack. The roof is now completely watertight. That’s the first step complete. Andy came back to help me fit the last sheet of roofing iron and then screw down the ridge capping, while I followed behind peening the ridge capping into the corrugations of the roofing iron. A very solid, proper, solid job of roofing. I’m glad that roof work is now over for some time. 

In the pottery we have been throwing and turning domestic items like cups, bowl and plates to fill out the shelves for our Open Studio Sale. 

I made 100 cups.

On the on-going pug mill front. I stripped down the big blue pug mill and took the motor off and sent it away to be re-wound and repaired – if that is at all possible? I should know in a weeks time. In the mean time, I took the worn-out vacuum pump off the purple pug and swapped it for the good one that was on the blue pug. So now I have a good working 3” purple pug that we are using for our white stoneware clay and the buggered vacuum pump is now on the blue pug mill that has no motor. A matching pair of non-goers. Well for the time being at least. I will get back onto that problem after our Open Studio Sale. 

The blue pug is hoisted up onto a tressle to keep all the new, clean gear box oil down in the gear box while I take off the motor. There is no easy, clean way to drain the oil without some mess, so I’m leaving it here for the time being. Hopefully the motor can be rebuilt and back on the machine within a week or so?

I rang my friend John Edye recently and enquired about the 4” Venco Pug mill that he had for sale a while ago. I bought a lot of his equipment last year when he retired. I didn’t make an offer on the pug mill, as I thought that I was going to get a couple of pug mills from other friends. As these have proved to be a little bit problematic. A rang John and asked if the big pug was still for sale and amazingly it was. I’m so lucky! I bought it over the phone and made the trip up to John’s place to pick it up. Luckily, it isn’t as far away as Melbourne and I could do the return trip all in one day. John assured me that it worked, but that it had a lot of corrosion inside the barrel. I’ve dealt with that before over the years by fill ing the worst holes with a home made epoxy based filler, or ‘wick-in’ thread sealant, that seeps into crevices and sets in the absence of air.

When I got the pug mill home, I was able to lift it off the truck and straight onto a wheeled, steel pug trolley that I had welded up in advance. I even had a vacuum pump cradle welded on underneath for the pump. These machines are way too heavy for me to lift, so having them on a mobile trolley is the way to think about them.

It’s interesting that this machine is the first model of Venco 4” vacuum pug mill and presumably dates from the late 1970’s. It has an inline plunger handle and all the castings are different from the later models.

I had a bit of trouble getting all the bolts loose to strip the pug down to clean it out. A few bolts needed the impact-driver to get loose and one snapped off, requiring the hole to be drilled out and the thread re-tapped. Slow and a little bit tedious, but all do-able.

The pitting is deep, but hasn’t gone through the wall and with a little bit of maintenance, will see me out I’m sure. I cleaned everything back to the metal. There was a lot of flakey white aluminium oxide to clean off.

Some etch primer, followed by a couple of coats of paint and it is all back together now and ready for work. I’m not too sure how John will take the new colour scheme I’ve chosen to cheer up the clay making area of the workshop? Pink, purple and mauve, with a little bit of black detailing. I like it!

When all of this clay making machinery trouble is all sorted out, it will make our life so much easier. I am committed to making almost everything myself. To be as self-reliant as possible, in food, in water, in electricity, in wood fuel, and this extends to clay and glaze making in the pottery. The principal difficulty that I am dealing with here is that I’m trying to replace in a couple of years, what it took me to build up over the past 40 years of life experience. I don’t remember it being so difficult in the past, but I guess that I was only dealing with one or two problems per year over that extended time. Now I’m trying to do everything at once. It is a bit easier this time around as I have more life experience and more skills, but I’m so much older now and I don’t have the same energy that I used to. I certainly find it harder to go back down to the workshop at night, after dinner and continue working. Although I still do sometimes!
