Cheap Epoxy Metal Repair/ Filler, and Initial Painting Model Cannon

So, firstly the cheap epoxy repair/filler. I paid $AUD9.95 for 100g on Ebay.

I note that the price has increased since my purchase, but still a lot less expensive than JB Weld.

I had dropped a tool onto my cheap compressor, and snapped off the muck metal outlet fitting. I tried cutting off the broken bit, re-tapping it, and blocking off the broken bit, but the muck metal part kept on crumbling away.

The broken fitting, after trimming it back with an angle grinder. Fitting a 1/4″BSP plug was unsuccessful.

So, I filled the broken fitting with the Chinese epoxy.

The broken muck metal casting filled with the cheap epoxy.

It took many hours to set hard, and I left it for 24 hours before firing up the compressor. I stood well back, out of the firing line, and powered up at 100 psi. All good. So I left it for a few hours, still all good. So then I did some riveting on my model cannon….

Initial riveting efforts satisfactory. Not perfect but not bad for a beginner.
First I riveted the sides of the carriage, then the bulkheads, then finally the base.
And then I used a pressure can to paint etch primer onto the sub-chassis, and the carriage. Hides a multitude of errors. My spray booth is a cardboard carton. Also melds steel, aluminium and bronze.
The etch primer shows the features which need further finishing, filling, filing, and provides a good foundation for the top coats.

The Chinese epoxy metal repair-filler is inexpensive and works well. Just a pity that it comes from a country whose government ignores international laws, and is territorially aggressive (Tibet, Taiwan, Tajikistan, South China Sea). And has probably lied about the origins of the Covid pandemic.

Silo Art Trail

Camping on the bank of the Murray River was just sublime. Good weather, beautiful surroundings, quiet and solitude, wildlife, brilliant night skies and endless blue day skies, exploring the Hattah Kulkyne National Park and Sunset Kulkyne National Park. Swimming, campfire cooking, good wine and good company.

But all good things come to an end, and wet weather was on the way, so we packed up, and set off home. First step was to negotiate the awful entrance track. 20-30 minutes of vehicular destruction and bone shaking. Off track driving is strictly forbidden to protect the easily damaged vegetation, but boy was it tempting.

We took a longer route home, involving an overnight stay in the western Victorian town of Horsham. That was so we could be at the opening time of the Stick Shed at Murtoa. See my post “Now, This is a shed” March 20 2021. And the route was chosen to see as many wheat silos as possible. North Western Victoria varies from desert to dry country, and the dry country is mostly used to grow wheat. Tall concrete silos dot the towns and countryside, and many of them have been painted.

Nullawil. Wow! It is big, awesome, moving. The first silo art was unexpected, and we quickly became enthusiastic to see more.
Mallee fowl sculptures made from corrugated iron. These have real character, unlike most “big” bananas, pineapples, koalas etc etc.
Old gynaecological habits die hard.
Senior local identities.
Local identities. And a couple of tourists (Scott and Libby)
This one was painted by a Russian artist, of 2 local sports teens.
Timber dray at Mutoa, would have been drawn by bullocks. I imagine that the 17 ton Ottoman bombard would have been transported on a vehicle similar to this in 1453.

The paintings typically take 2-3 months to complete. Cost was not disclosed, but the increased tourism has more than justified the cost. We did wonder if upkeep of the paintings had been factored in.

Returning to model cannon next post. Riveting stuff!
