    Strictly IC magazines for sale.

    I use a company called Freightcom, they give a number of quotes from different couriers and freight companies, there is a huge price range in couriers and I think they get a special rate as it's essentially their account you are using so you get their discount. I don't have any other connection...

    Upshur's opposed twin engine

    There's a how to select the right tool video on their site that shows how it works and you could likely build the tool in a hour but they aren't too expensive.

    Strictly IC ISSUE 37

    The problem with that 'sunk cost logic' is that when the rights are sold, the owner will possibly get nothing after he dies. I appreciate that the reason they aren't being sold is because he possibly can't recover the original cost, but the ROI isn't going to get better with time.

    Mastiff lc mason engine REDO .

    Everything is ok if you are making the mating gears, some combinations of DP/module and pressure angle will work better than others but if you make the mating gears it should all be good, within reason.

    Harry Wedge oscillating engine plans

    There are a series of pictures of the engine, no plans at https://www.flickr.com/photos/28865130@N04/albums/72157685361917640/ I can't see that pictures of the engine could be copyrighted unless they are reprints of pictures owned by someone else.

    Mirror Finish Fly Cutter

    It's better to buy them this way but to improve the facing finish of an end mill, grind a small radius on the corner.

    Powder paint for model engines

    Toaster ovens have no insulation, if you can wrap the larger flat surfaces with some fiberglass insulation, that might get you there though you'll have to watch the controls and such so they aren't overheated.

    My version of a Die Filer From Bar Stock

    I tried that, it doesn't work with 30 year old TurboCAD 16.2 :p and Alibre doesn't read AutoCAD 3d dwg either, BobCAD does though.

    Sandblaster!!!

    I have the Princess auto sandblast cabinet, I got it on sale though, so cheaper than current pricing. I'm using a $10, 10 watt Aliexpress floodlight and I still have only the siphon gun that came with it. The biggest issue I have with it is that the angle of the hopper is much lower than the...

    End of an (electrical) era

    That's all fine if you know how to build the circuits, many that grew up making engines with points can't do that. I know it's simple, but only if you know how to do it.

    Machining Projects: Book review

    The problem is, just like Taylor Swift seats for $5000, there are still people that will buy them, maybe not at $6800 but well over the original $24

    Sandblaster!!!

    Before you get too worked up over cyclones and 'clearing the air', take a look at the Bill Pentz site on cyclones, he's the guy they copied the 5 gallon pail cyclone from. Pay attention to the parts that talk about how effective they are and what their limitations are...

    Can you remove anodizing color from aluminum?

    I found that, in Canada anyway, though our regs are pretty much dictated by the US, only 75%+ is regulated as an explosives precursor

    Can you remove anodizing color from aluminum?

    Apparently it can be stripped with a mix of antimony trioxide and sulfuric acid 40% at 80 °C that will leave an antimony deposit, then to remove the antimony, a dip in nitric acid 30% at room temperature. Nitric acid is nasty and heavily regulated, so probably not a great solution. In the past...

    FreeCad .21.2 22dev Anyone happy?

    It's been said before, maybe too many times for some, but Alibre Atom will do most things we need to do, and it's easy to learn, at least it was for me. Yes, FreeCAD, if you can get past the learning curve is more capable, but Alibre Atom is only $199 and you own it forever.
