Files, emery cloth, wet and dry, plus loads of finger aching flatting and elbow grease, and that is just to get it to looking almost nice. Every machining mark has to be removed and the surface got to a flat satin like sheen before you can proceed any further and start to polish. Otherwise you just end up with what looks like a bit of polished up scrap.

So don't think that getting a good finish by machining is the hard part, it is nice to get a good finish, but that is only the first bit.

That's what I thought Blinging was. :scratch:

I fully expect to spend a long time carefully sanding and buffing after I have got it running. What I'm endevouring to do at the moment is to get just a relatively decent looking finish as I make each part, I know that I'll be doing it all again when it comes to the "Blinging" of the build, but it gives me a great sense of achievement to spend a little time removing the worse of the machining marks.

Tim,

Flat surfaces and flatting and rounding sticks are what you should be using, fingers are no good, they distort the surfaces too much.

Here is the finished blinged up engine of mine. A little different to what you are making, but still basically the same engine.

Maybe a little over the top, but it does show what a few changes can make to the overall look of the engine.

Get yours running first, then strip it down and do all the shiny bits afterwards. Then you know you are not wasting your time.

That is very true, I've found that putting a sheet of wet+dry on my granite plate to be a good means to flatten and polish up flat and even convex shapes, and using different sizes of drill shank ( not the cutting end, the smooth round end ) for concave shapes to be good too.

Your blinged up engines look really nice, :thumbup: it looks like you have milled out a seperation between the 2 cylinders, square on one and rounded on the other?

Tim

bogstandard:
It is rounded on both Tim, and then I recessed the sides to take a little bit of colour.

But that shaping wasn't done until I knew the engine would run. Why waste time and effort on a none runner.
