    Thanks. Cleaned another drain with it today, it was full of black gook (iron pipe) so we made quite a mess. Got the drain working though.

    Looks like I'm gonna have another 30 of those heatsinks to do. Just got an email.

This one coupled straight onto the pressure washer hose and with a few hundred psi was stiff enough to get past the clog apparently. I drilled the holes at #60 (0.040"), but I think smaller would work better to get the PSI up a bit higher. There are 4 holes angled at 45 degrees to the rear and 1 forward. I just roughly copied the design of the commercial unit from memory but made it to where I could manufacture it and use the fittings we had on hand.

    Those look sort of hollow (like curls)....were you aiming for hypodermics?! Bet you'll be finding those for weeks....and not in a good way! At least they look big enough that you'll be able to see them sticking out your finger.

    Nothing special. I've been wanting to replace the jaw liners for a vise I have. I milled, drilled and screwed together two sets of nylon liners and added a four rare earth magnets to each one. Then I put an aluminum skin on them. Hopefully they last? Click image for larger version

    Works well.
    If I had a block a steel big enough I might have done it that way. I'm sure it would be sturdier. Although an advantage of using the tool post is you can easily change the height and make shapes other than a sphere.

    31 heatsink angles from a guy I know. Actually MIL work, but he is a sub to another company that is a sub to yet another. Vendor did not get the surfacing cut quite close enough to the mount surface on the other side of the angle, so the devices did not sit right.

    Had fun figuring out how to reach the spot, which is about 0.2 from one side of the angle, and that side 3" or so wide. Too close for any of my stub arbors, too long for any extended end mills.

    Finally did it with a Woodruff cutter that was big enough in diameter to clear the end mill holder I used to hold it and get the reach. Finish was "OK"... all that was needed was clearance for the edge of the PWB. He is going to have to get the pieces re-alodined after he gets some double-stick tape (used to hold an insulator sheet) off of them.

    Just one groove down the length, with the parts fixtured on an angle plate. Had to use paper on clamp surfaces because they are also heat transfer surfaces that get greased to the chassis.

    Hi flathead4

    I too have a SB9A and this will be just the ticket. Thanks for the additional information, this will let me add another project to the list, which is getting longer as each day passes instead of shortening as it should be

    That is a boring head for a mill that you are showing as a ball turner. Can you elaborate on what and how you use it? I've got a boring head that would work if I can see more of the details of you setup. I'd really like to have a ball turning tool, yours looks like a possible project that I could do.

    I used a spare boring bar holder with two Oilite bearings from McMaster. The assembly in the foreground is made from 1/2" drill rod threaded into a chunk of scrap CRS. I turned and threaded the adapter with it screwed onto the drill rod and held in a collet. My boring head is a cheap import and there is a some play in adjustment screw so it is a bit tedious to use. If I were to do it again, I would make the adapter shorter. My lathe is 9" South Bend and as you can see I have the cross slide pulled all the way back and that only allows me to make about a 2-1/2" ball. Also, the cutters that come with the boring head are the wrong shape for this use. I ground a piece of HSS to a shape that worked but I need to refine that a bit.

    Unexpected (marginal) benefit, an extra couple of mm of Y travel as the countersunk screws stick out less than the original cap heads.
    Very nice ATW,I need to make something similar my Mill has no rubber apron at all.
