Back in the late 80's early 90's when I worked at Westinghouse In Sunnyvale, CA I used a power scrapper to make steam turbin housings steam tight. It takes a year to be any good at this, either you aquire the ability to do the job or you have to move on to something else.

I've got to do a bit of scraping and was thinking of doing this. How well has it held up and other than making the stroke shorter, would you make any other changes?

Hi! Absolutely no problems 👌, but consider adding balancing weights. And I actually did the most of the scraping of my big milling machine table by hand, so my advice to you is that make the power scraper before, not after 🤦‍♂️😁

Curious, the brass pin isn't giving any grief? Did it make it through the rebuild?

@GarageOfTool Жыл бұрын

Hi! I've been running that scraper for a pretty long periods and it's still running fine. The only thing I would change is the stroke lenght, which could be smaller.

@@GarageOfTool That's awesome! I'm crippled with overbuild-everything syndrome. Neat to see something built reasonably to accomplish a goal. I end up N projects deep when I could have just taken the value add way out.

Probably a scraper build by people never scraped themself… nice mod!

I've actually scraped tens of hours using this scraper, still working 💪. Beats hand scraping, but obviously PPI is smaller due the long stroke.

why there is no last blueing to see how good scraping was?

@GarageOfTool Жыл бұрын

Hi! This was just scraped to demonstrate the scraper in action, but the plate was also getting better, though not perfect yet. Also the scaper was cutting pretty large areas and I wasn't aiming for any specific "points per inch"

@@GarageOfTool but then i think all point of video is lost because you are "hiding" end results. its just looks like scraper did very bad job and you dont want to show last blueing because scraper is useless. its just first impresion after watching video, probably you got great flatness but watchers cant see that without blueing.

@craftzars Жыл бұрын

but anyways great video, i have also plan to build cheap scraper

@GarageOfTool Жыл бұрын

@@craftzars Yeah I understand your point, but the final flatness results depends only on how many bluing cycles one is willing to do (pattern will though be more coarse due the long stroke and large radius tool)

How do you do the flaking on this?

@GarageOfTool Жыл бұрын

Hi! I haven't tried to do pure flaking with this, but instead, a cross scraped surface will anyway hold oil etc. nicely, so there's a little advantage to add final flaking for most parts.

@ShopperPlug Жыл бұрын

@@GarageOfTool Interesting, didn't know that. I thought half moon flaking was the only way for the oil to stay and lucubrate. Thanks for the reply.

Iwill say only hand scrapper .power scrapper of course is fast but it can never be like hand scrapper because if you pay attention 100%also som wher of the part will be not corect as all.iuse of hand scrapper ca 20 years also ihave power scrapper. If samoen don’t exapt my experience pleas let me know and why? Thank you Best regards sina-von Austria 🇦🇹

Hi! Yes, this is power scraper is definetely made for the cases where you have to take a lot of material out as fast as possible. Hand scraping is of course more controlled process, but hand scaping e.g. 20 rounds of big surface plate, is a sweaty job
