G'day everyone.
In last weeks video... I made a real hash of things. My plan was to convert a cheap reciprocating saw into a basic power scraper, to help me scrape my lathe flat. Scraping generally takes a long time to do (it can be in the range of hours spent depending on the size of the project) and it generally takes a lot of physical effort. A power scraper can cut down on the physical effort and time it takes to scrape.
My previous power scraper was a bad design, and a loose screw caused the yoke to jam and crack the casting. I could have gone back and used my failure to redesign the gearbox entirely to accommodate a new scotch yoke design. However, I think I can bypass all that by modifying an air tool.
Even better the design can be done in under a day using minimal materials and it is easily reversable, something that was not necessarily possible with the design that I was planning to do.
I hope you enjoy the video, Cheers.
