    Demagnetize

    A soldering gun (not iron) will work for small items. Stick item in loop that forms the tip (not touching the tip), turn on gun, withdraw item slowly to a distance of three feet or so before turning gun off. A larger loop tip can be made from heavy gauge copper wire. Look at yard sales...

    Brian builds Atkinson Engine

    If you can tolerate slightly elliptic sections instead of perfect circular arcs, then tilting the mill head (if that's possible) and traversing the table will do it. See my RADIUS program for the necessary computation.

    Accurate cross holes - without a jig.

    Or, if your geometry permits, mount the work in the vise such that a small portion of the jaws aren't grasping anything. Use your indicator/edge finder to find the middle of this gap. In effect you're using your vise jaws as improvised caliper jaws.

    PM Research No. 1 Build

    Your argument makes sense. Modern commercial nuts are often chamfered on both sides. If the chamfer is there for your purpose, as opposed to just making them burr-free, then it would be logical to chamfer both sides so the operator can't get it wrong.

    PM Research No. 1 Build

    For model nuts, I use... D = major bolt diameter 1.5*D = across flats nut size 0.9*D = nut thickness I've always mounted nuts with the chamfer/rounded side up. I'll be interested to hear an argument for inverting that choice.

    Yet another Quick Change Tool Post

    Another use for the Al holders is to hold a wiggler to aid in centering in the fourjaw. I prefer to use a pump center but some folks like wigglers. Like Bogs, I can't imagine that the grade of steel for toolholders is a major concern. The loading at which toolholder strength becomes an issue...

    Yet another Quick Change Tool Post

    Ian, If you set up in production mode to make tool holders, consider making four or so solid ones in aluminum to use as holders for stuff other than cutting tools. I use one for a DI to center stock in the fourjaw and another to hold a Dremel as a poor man's toolpost grinder. The more you use...

    gripping the inside of a small hole

    How about getting a pair of those snap-ring pliers that have jaws that open when the handles are squeezed. Grind the points down to the point where they will fit into the banana jack, It wouldn't provide a wonderful grip but it might be good enough for your purposes.

    I can't quite place my finger on it...

    Indeed, although a rollicking good performance of the lumberjack song... http://www.youtube.com/watch?v=5zey8567bcg will still have me laughing until I hiccup. Anybody remember John Cleese as the minister of silly walking? http://www.youtube.com/watch?v=IqhlQfXUk7w I think of this sketch...

    Steamer, I don't want to talk to you no more, you empty headed animal food trough wiper. I fart in your general direction. Your mother was a hamster and your father smelt of elderberries. ;D

    I can't quite place my finger on it...

    I know you lot are weird, Bogs, but it's still a bit of a push. Imagine getting up in the morning and saying to yourself (I'm pretty sure this guy talks to himself), "Today I'm gonna don my kilt and my Darth Vader helmet, grab my bagpipes and unicycle around the parking lot in full view of...

    Does anybody sell model (I.C) v4 to v12 engines, exept Conley precision?

    Ian, If you read back through Dave's posts I'm sure you'll appreciate the fact that he's one of our most welcoming members. The idea that he would construe the forum as some sort of exclusive enclave closed to newcomers is, well, just utter rubbish. The absence of visual cues in forum...

    Philistine! Why, the very idea - everyone knows that would bruise the gin. I keep the olives in the grenade.

    Cheap and quick solution to a problem

    I plan to use it for any job that looks like it needs a Foredom. :) Seriously, I don't have a particular use in mind at the moment but I've often been dissatisfied with my Dremels and I wanted something of professional quality. The handpiece is much slimmer and lighter than trying to hold a...

    Canada Day

    Happy Founding Day to our friends in the frozen North. I've heard tell that some of you tilt a few back on this day. If that's true, have one for me.

    Precision Tool From Scrap

    Tom, Before you spend a lot of time on the search, better read post #8 in this thread. BTW, I don't think Guy Lautard is going to appreciate the new last name you've given him.
