    Yes, the world is way more colorful and nuanced. My first love is photography and I'm amazed how I can now see subtle shades of white. No two pieces of paper are the exact same color. I also just...

    Silicone mold casting is great if you can stand the expense for the materials and have access to a vacuum pump to degas the stuff. You can also buy fillers for the resins, carbon fiber or even...

    I have this same issue and no budget for good bore gages. You need too many of the darn things anyway. There are several systems like this- Octagon Precision | LMM 600 : ULMM
    I assume they're zero'd...

    I agree with the above. I went with simple lenses, corrected for distance vision, because I didn't want any artifacts. My vision is fantastic compared to before. I wear bifocals with the lower...

    Did a survey a while back and concluded that they're all a compromise. We ended up buying nothing. You might have a look at these guys- Home - MDA Precision

    If you have trouble cutting Delrin, you might be in the wrong business! New sharp coarse blade and don't run too fast. Clear with air blast.

    FWIW, I've had a terrible problem with sticking pistons on several different makes of cars. I think it's climate related and the only fix is just buy a new/rebuilt caliper and piston. It's all for...

    Diamond isn't a good choice for steel. How long is the wire? I'm assuming short pieces, but could be way wrong.

    Just checked the website and they do specify carbide anvils, the diameter and the measuring force. Took all of ten seconds. That said, I suspect very few people have the knowledge to get full benefit...

    It's amazing people have such faith in a presidents ability to quickly raise and lower prices. If anything, the groundwork is laid several years back. Administrations tend to take the blame for the...

    I buy whatever random ones I find at flea markets and such. If the post is small I put a piece of shrink tube or rubber hose over it so it doesn't clank. There are a couple styles, cast, machined,...

    Remember that the part that overheats is not usually the root cause of the problem. If you replace what appear to be diodes, they will likely just fail again. The circuit needs to troubleshot and you...

    Well, I'm happy it was posted just because I've never seen or heard of such a thing. Interesting tool for a specific type of job.

    I can imagine using a milling attachment to hold a live tool or some other weird thing, but putting a cutter in the headstock and actually milling with the thing is a PITA. Any MSO would be an...

    I've gotten too phreaking lazy- I'd just drag it down to the local waterjet place and they'd pop it out zip zip for very little $$. Probably the same with plasma or laser.

    One of the best lathes ever. That said, they aren't very big and you'd want something larger if you do large work. The lathe is plenty big, but the work space is limited. Horses for courses. Check...

    I try to save money by doing everything myself. Doesn't always work out that way.

    A friend once said when I was asked to machine a part, he figured my first thought was where to mine the ore.

    I'd think when things get sluggish, it's too cold. My lathe and MSO work far colder than I'm willing to put up with, but the surface grinder is another story. It's hard to slide the table, my arm...

    It's not hard to grind flat, but you can really mess it up during removal. I'm a big fan of this stuff- Home - Aquabond Technologies It's a hot-water-soluble thermal adhesive that people in the...

    I find that lapping film tends to round the edges near holes. The cast iron lap is the way to go. I'd use something smaller than the surface to be lapped and a lot of measurement.

    Not sure politicians are capable of walking and chewing gum at the same time. Not even sure they're very good at either one when done singly. I also notice that peoples' ability to evaluate risk and...

    That's just nuts. I like the box solution. It's so much material I wonder if you could EDM it to near final size?
