PekkaNF:
This is a thread I follw with great interest.

Any informative pictures on color transfer and scraped marks?

Pekka

Joe d:
Sounds like you're making good progress Steve.

Looking forward to the first turning on the Model 1 Mark 1 Fletcher Ladder Lathe :clap:

Thanks Pekka, Joe. :beer: I keep thinking photos of scraping must be as boring to people as scraping itself. But I can see that maybe a couple pictures of the blue part might be useful, so I'll take them.

One point I want to make about files. They are NEVER flat in my experience. If you realize that you can use it to your advantage (and if you don't, they will mess up your work).

So, flip your files over when filing and get a feel for which side is cutting in the center and which side is cutting at the ends. imagine how that is cutting the work. And then use the appropriate side for what you want to do and apply pressure in the area you want to cut, as well as keeping the stroke length right not to cut into areas you don't want.

With a file laid flat, you will be able to feel resistance in it along its length, and know where it is cutting.

On this level of flattening things, filing involves a lot of visualization and feel, you cannot rely on just the idea that a file is flat and rub it over a surface, because, guaranteed you work will suffer. Is the file following a curve, or cutting the ends like a double-ended scraper, or rocking at the center. You must feel and imagine what the action is.

And of course frequent checking to make sure you really are cutting where you want. This is especially important if you are new to this. As you get more familiar, knowing what file face you are using for a particular high spot becomes second nature.

Nah, not boring at all. I find it interesting and it helps some of us.

Keep up the good work!

Okay, so here's the 4th edge blued up. It's been filed and scraped some already. the blue has begun to move on the left from a small spot to start with. the high area on the right is getting larger, too.

If the edge was also tapered and the right side was the wide side, I would scrape everything blued except a small patch on the far left, which I would leave. When the straightedge was placed for a rub next go-round, it would ride up on the high spot on the left and mark high spots mostly toward the rght, which would force stock removal along a new straight line, angled inward more on the right.

Scraping those would have the effect of reducing the taper, yet maintaining a straight line. I'd repeat this process until the width of the scraped areas all along the ways measured the same -- in other words, parallel with the reference edge. Then I would continue scraping the whole ways, including the part left earlier to bring the whole surface into truth, and now parallel, too.
