    Ideas as to how to embiggen this hole?

    The potential issue I see with that is how big is the current hole? If it’s bigger than the pilot on the holesaw the holesaw is just going to walk all over the place.

    Ideas as to how to embiggen this hole?

    Like a one way clutch or engaging and disengaging? A bicycle freewheel is a one way clutch, if you need something that engage/disengage I can’t think of a bicycle part that would work. Do you know the chain pitch? Bicycle chains are 1/2” but narrower than 1/2” pitch industrial chains.

    Ideas as to how to embiggen this hole?

    DIY Scraper

    Here’s a drawing from Edward Connelly’s book Machine tool reconditioning and applications of hand scraping. The angle of (3) is how much negative rake there is. The drawing shows the blade as being double beveled, that way you can flip it when the edge on one side gets dull. This book is...

    DIY Scraper

    3/16” x 1” flat bar makes a good scraper body. I cut a tang on the back and put a file handle on. I haven’t really used HSS much for scraping, so I’m not sure what the ideal geometry is, but for carbide scraper blades you want 5ish degrees negative rake and a large radius to the cutting edge...

    Rant about no name vs name Brand stuff

    I’ve been fairly happy with inserts from aliexpress as well. All the ones I’ve bought that had their own branding have been decent. The only ones that were duds came in “sandvik” packaging, which wasn’t even noted in the item description, I wasn’t trying to buy knock offs. I’ve hardly bought...

    Sourcing Metal | General Discussion

    Beach road steel sales in Hamilton sells “secondary” material. The same folks run a scrap yard nearby. I don’t know of any other places like that but they might be out there. I’m not sure how the actual policy is worded but my understanding is that they will sell to Canada but only to...
