    Be careful with that thing; I understand weird stuff happens once you hit 88mph.

    Not sure, but I owned Miles Gordon Sam Coupé (which is kinda related)

    I did once hear a story about a full computer kit (can't remember the brand) that was returned as not working. On inspection, the buyer had put all the components on the board perfectly, with the job being incredibly neat. Shame he'd used superglue instead of solder.

    Thread dies, question.

    Even in mild steel, it strikes me as a little odd that it would be easy (little resistance) to cut an M10 thread with no cutting fluid. Sounds like the rod was way too small (diameter)? I can't remember the source, but I was taught to reduce the diameter by 10% of the pitch - i.e. for an M10...

    Dovetailing 9mm birch plywood

    There's a right tool for every job. Unless it's a jigsaw. That's never the right tool 😁

    Dovetailing 9mm birch plywood

    Plywood + dovetails are not usually a great combination. A simple box joint would likely be less hassle, and less likely to split the fingers off as the base of each finger would usually be wider than the base of a dovetail. Your jig may well do box joints as well as dovetails.

    Started with a 48k+. Many good memories of "Lego" like low resolution graphics, colour clash, and terrible sound :) Barring a bit of time on a school RM Link 380Z, that Speccy basically started my career in software engineering.

    Who has achieved 1000cfm at their static machines (a la Bill Pentz).. if so, how?

    That's a more difficult one, as that information seems to be lacking for the Thien Baffle (vs cyclones). Certainly it will drop the airflow, and I don't think they separate as well as a cyclone. However, they're easier to build, and if the separation is good enough to not eject visible dust then...

    Josh - consider also a Thien Baffle (J. Phil Thien's Cyclone Separator Lid w/ the Thien Cyclone Separator Baffle). They're significantly easier to build, and may be a solution to the problems with option C that Mike's pointed out.

    Who has achieved 1000cfm at their static machines (a la Bill Pentz).. if so, how?

    Interesting. Are filters directional though? I suppose if it's already going through a cyclone then it's not like you'll be bombarding them with chips...

    Who has achieved 1000cfm at their static machines (a la Bill Pentz).. if so, how?

    At the longest run from the motor+impeller I'd guess I would have had about 8m of ducting (up a wall, along the ceiling, and back down) and then 1m of 100mm hose. Even at that length it could "steal" a 1" (25mm) cube of wood and pull it along the ducting. Granted that system did not have a...

    Just checked: based on the size of the housing I'd guess maybe 13".

    Who has achieved 1000cfm at their static machines (a la Bill Pentz).. if so, how?

    I bought a 3hp Fox F50 843 (for the motor/impeller unit only) and integrated that into a ducting set up for my old workshop. That might be a cheap way of getting a reasonable blower. Baldkev makes an interesting point; as a cyclone does rob you of airflow. I did the same - no cyclone, and an...

    Best easy finish for Walnut?

    A few years ago I experimented with some different finishes on ABW; so this might be of interest: How to darken American black walnut (and get a good sheen)?
