: I tried the scraper for the inside woodwork - not too impressed,

A scraper, like every other tool, does not reveal it's secrets without inquiry and persistence. The rewards are worth it!

Scrapers are deceptively simple in appearance. It seems like their use would be simple to discern, but it is not.

First, like all blade tools, they are not sold sharpened. It may seem sharp out of the box to a novice, but it is not.

Sharpening is the first step. This can be done with a single cut file, but then, you will have to learn how to use this tool,
and that's another story. The simple method is with a belt sander using 120 grit. Look carefully at the angle of the current
bevel on the blade edge and duplicate that angle as you hold the blade against the belt. MAKE SURE THE BELT IS MOVING
AWAY FROM THE BLADE EDGE.

Touch the new edge with your finger. Does it feel sharp? NOW try scraping a wood surface. Can you feel it really cut the wood?
Will it create fine curly shavings like the best hand plane? IF NOT, you haven't got a sharp edge. Try again until you do.

Hold the scraper handle with one hand and place the other hand or fingers near the head. The handle hand pulls while the head hand
applies downward pressure. Practice long smooth strokes, following through, like a golf stroke.

Hold the handle HIGH or LOW? The angle the handle of the scraper is held, relative to the wood surface, is
critical and changes the cutting action. For rough cuts of rough surfaces like glue removal, hold the handle very high to knock off chunks. If you hold the handle low while trying to remove glue drips the scraper will skip and dive and gouge the wood surface.

Once the surface is cleared of glue, use a low handle angle to scrape fine shavings.

Finally, the scraper, like EVERY BLADED tool, works better if you SKEW the blade in the angle of travel.
This makes the blade SLICE the wood instead of chop it. You will find it works easier and cleaner.

For rough scraping I use a scraper like the one pictured. I has a four edged blade. Shape blades on the belt sander to different arcs
to scrape deck and hull interiors and round blade corners so they will not gouge. When shaping or sharping blades use slow passes
over the sanding belt and have a bucket of water to cool the blade. If you let the blade get too hot it will loose it's temper. No, it won't be miffed at you, it will not hold and edge!

There are a great many sizes and shapes of scrapers to fit up into your stems and every place you want to scrape.

Once you learn how the sharpen and use a scraper you will fine them indispensable!

All the best,
Rob
