The above restoration was done almost 2 years ago. Whin it failed, I was quite fed up with is, so the enghine was shelved for about 2 years.
Right now I thought it was about to start the re-restoration of this engine.
In the mean time I was able to buy a new engine unit on ebay, consiting of the engine baseplate (the silver pice), engine brackets, pipework, pistons and cylinders. This was a nice piece to solve my blocked pipes issue.
I also found out that the brand VHT did also sell heat proof silver paint which I could use for the chrome sides. Ofcourse real chroning would be better, but after consulting several companies about that I found out that chroming would be (way) more expensive than what the whole engine was worth.
There where a few things that needed to be done:
- Repaint the baseplate again, I last time used a satin finish by accident, and that just didn't look the way I wanted it.
- Repaint the firebox chrome side with heat resistant silver paint.
- Repaint the black firebox parts, since they gathered some rust in the dampy shed where I left it for a while.
- Drill out all pop rivets and replace them with copper ones, using metal ones like I did the last time wasn't a good idea, I really need to use copper ones, because the metal ones rusted right out of it.
So first off it was time to get rid of the paint again:
Soon enough the base looked very nice again:
And here you can see all parts waiting for assembly:
One of the harder parts was getting the right rivets for the sight glass. For one or another reason the holes in the faceplate of the boier where quite a lot bigger than the "mamod rivets" that are sold on ebay. I eventually ended up with copper rivets that have a metal inside, they worked fine but look a little bit oversized.
After assembly, the engine looked like this:
Quite a pleasing result, but the real question ofcourse was: would it run...?
The answer is yes! But unfortunately, even the VHT paint couldn't resist the heat.
I guess there's just nothing you can do about that, even the original SP5's have problems with that, so I just have to leave it like that (quite hard for a perfectionist like me :) )
