DIY Vintage Machine Japanning 2

About to get hot
I decided that the Japan job I'd done wasn't up to scratch. Put it in the oven for the requisite three hours. The smell in the kitchen (the machine wouldn't fit into the BBQ) and the subsequent attempt to rub it down was unsuccessful.
After the oven, not very smooth

  So I stripped it all again and painted it with enamel. Well, I have to say that the enamel's biggest downfall is that it's so damned thin! The Japan from the methylated 78 was very thick and was indeed quite suitable for the job but it was a bit lumpy. In retrospect, I should have just filtered it through a stocking.
I think I'll probably have to make a mixture out of shellac and asphaltum and re-Japan the machine.

Damn, the "asphaltum" I ordered from Jacksons turned out to be lump rosin. I'll be sending it back of course (I assume they'll want back, since it costs twice as much as asphaltum), but it meant when I decided to redo the Japan, I used the dissolved record mix again. This time I practically poured it over the base of the machine. I'll leave it four or so days to dry (or longer if necessary), sand it back then fire it in the BBQ (after making a bit of room there, or turning it sideways) since I'll probably die if I use the kitchen again (from either fumes or being subsequently murdered). Haven't taken any photos of the new Japanned surface - it looks pretty much the same as the last time, only a bit smoother. This time I also mixed some Shellac into the mixture and filtered before pouring. Brushes must be used only within a few seconds of the pour or else you'll get definite brush strokes appearing and staying on the surface. Yes these can be removed later, but it's not easy, particularly after firing the machine, when the Japan is really quite hard. I'll also attempt to remove more of the mechanical components beforehand - it scared me when after it was last fired the machine was completely siezed. I've bought some tri-flow oil now in anticipation of this happening again.
OK, more later, but I'm convinced that the dissolved record will give the most accurate surface now. Alternative is to proceed with enamel, giving it about three or four cans worth, or about 30 or so coats to build up enough paint to exceed the depth of the casting marks. If the surface remains dull as it did the first time, I will shine it using more shellac, dissolved in metho and applied using a cotton cloth.

A couple of new machines

It's getting a bit beyond a joke now. I've bought two more machines and was given one. They are:
1891 Singer VS-2 Fiddle Base.
1950s (serial number unlisted) Singer 227M, and
1950s (probably) Liberty (Japanese Singer 15K clone).

Liberty is here
Best thing about it is that it's a hand crank machine. Thought that it might just fit the VS-2 but the mounting isn't there for the older one. Still, after lubrication it goes like a beauty. That said, just winding a bobbin was initially fun but quickly became exhausting.
The VS-2 is next
As you can see the decals are almost non-existent. Also, that motor had to go. It was a conversion, probably in the 1950s, had no controller at all, and had no plug "for safety reasons". Does one really need anything more? Out it went, with all its accompaniments (brackets, belt). You can see that the original coffin top came with it, so I'd really like to restore this machine back to its original state. Kind of expensive, considering. The metal parts all need re-plating (in nickel), so I got rid of all the old stuff and polished it up. If it looks crappy later, I'll do it, but the cost is getting up there.
The 'paint' you see on these old machines is actually not paint at all, but "Japanning". This is a mixture of asphaltum, shellac and boiled linseed oil which is painted on then fired at about 140C for several hours. I think this machine deserves a new covering after 122 years of service.
So, I was on the look out for a treadle table for it, and found one. $50 later and I had a 1950s table. OK, not time matched, but it'll work. It also came with a Singer 227M. Straight stitch machine with no booklet, attachments or anything else (deceased estate, the family threw a lot of stuff out, as they do). The machine is quite a good one, but with no ZZ plate or attachment, or light, motor etc it's pretty useless. Anyway, have to go, but I'm going to melt an old 78 record in methylated spirit and add some boiled linseed oil (the records consist mainly of asphaltum and shellac), a common practice apparently and onto the hooded BBQ it goes for three hours. Let you know how it turns out.
EDIT: Here's the 227M:
