Newly aquired favorite tool

[Capt652]

I recently bought a new tool for plastic parts clean-up that I find does a remarkable job in it's intended purpose. It is called a 'seam scraper'. The scraper blade is three sided so at each end there are three edges for a total of six scrapers. I am currently building a 1:700 Fujimi Nagato which of course has many, many tiny parts. This tool quickly and cleanly removes that fine mold line without damage to even the smallest part. IMHO this method beats needle files, #11 blades or sandpaper.

I'm a tool junky at the most extreme and I love when a tool works well.

Such three-sided hollow scrapers came originally from the mechanics' tool chest, a bit larger though.



They are also made with the standard 2.34 mm shaft of the rotary tools and are available from jewellery makers' supply houses quite cheaply. They are inted to be hold in a pin-vice.

As a machinest and toolmaker, these were used for de-burring lathe turned items and parts machined on milling machines.

That is exactly what I use my real-size one for

They are also handy for deburring drilled holes.

What name does this tool go by with jewelers and machinists, "seam scraper" seems something adapted by hobbyists...

[wefalck]

Many things don't have names � the description is hollow three-sided scraper. There is another variant that is not hollow ground. You can find them in jewellers' (on-line) supply shops, usually in the same section as the burrs, because they have the same shaft.

Thanks, just wanted a term to look under when going to such sources.
