Thread: What did you do today?

    Don't know on waterjet in a cold shop, but you have to keep the laser cutters above freezing as they use watercooling to cool the laser tube, and if it freezes when not in use, it risks cracking it.
    I also don't think 60-80w will get you metal cutting ability, when I get my next section of shop built, I'm going to make my own plasma table for that task.

    Can water jets use RV antifreeze or a mix? Or does it require something like pure distilled water/etc?

    Here's where manual focus is your friend.

    There are no stupid questions. But there are lots of stupid answers. This is the internet.

    The manual says pure distilled water, but I've read on the net that RV antifreeze is ok, its in my office so its a non issue for me anyway.

    This also arrived today, Its a Perception/Matrox control computer. Its part of a laser scanning solution that mounts to a cimcore/romer portable cmm arm giving non contact laser scanning but with portable arm cmm accuracy. Which I also have one of after fixing a broken one a while back.


    I've been hunting one for literally years now after buying the contour probe sat above it (I got 3 of them actually) without the interface hardware in what must have been stitch up of the year by a seller (to be clear, the seller of the probes, not this control computer). The pc came locked with the keyboard disabled and no details, but looked like it booted to a login, so I gingerly powered it up, and got it to boot from a usb stick and used clonezilla to network copy the hard disk somewhere safe. Then I reset the administrator password, and found the old default ip address. Configured a machine into the same subnet and managed to log into it. A quick poke about and it seems to be still autostarting all the special matrox software and have valid licenses.
    Now "all" I have to do, is make the missing cables up (having never actually seen even a diagram of them), make a probe mount that fits the romer arm and the top of the probe head as its a stud mount where it was on a cmm, work out the resistor value that tells the arm itself its got a laser probe mounted, get the probe and the interface to talk correctly, and then get that to talk to a really old version of scanworks running on a laptop on the same network which reads the arm itself and tells the probe when to initiate a scan so it can get the exact co-ordinates when it scans.
    Chances of getting it all to work flawlessly? not very high, but if I pull it off, it'll be awesome to have a laser scanning capable pcmm in my little fiddle farting amateur hour home shop.
    Don't expect better pictures mind, I still can't work a camera even if I know my way round embedded computers and industrial hardware

    Last night I met a guy from Philadelphia at the TSC store in Aberdeen, and sold the four good tires and rims 3 years old, 10k miles) for $100 (I was asking $125).




    Today I met the tow truck from www.peddle.com, removed the driver seat (to put in my truck), and got $130 for it. I had advertised the car with the good tires for $350, but got some responses that seemed to indicate they could just get it inspected, tagged, and drive it, and many of them were from pretty far away. So I got a total of $230, about 30% less than I was asking, which is about what I expected.

    There will probably be some metalworking involved when I pull the bench seat from my 1989 Toyota 4WD pickup. Then I will have bucket seats.

    MrFluffy, we or I will say they, had a portable CMM at the Western Star truck plant .. oh about 12 years ago.
    They used it to check tooling and fixtures some of which I made.
    Came in a big case, had a printer I think , and was quite pricey..

    What did I do..
    Even though it did not get above freezing, I test rode 2 bikes today.
    A Buell 1125 R, that one is pretty quick and has a wonder full front brake.. not what I am used to.
    And a Heritage Softail with a sidecar I just mounted, needs some setting up.
    Two very different bikes but the same year.. at least it was sunny.,

    Wonderful front brake. Yep! The same kind of brake that sportbike riders and racers have been using for 30 years.

    Do yourself a big favor and take that Buell animal out for a few experiments on dry pavement on a sunny day. Do some wheelies! When you're comfortable with the beast, do some *stoppies*.

    But never forget you're riding a powerful beast!!!

    Have fun...

    I don't see a lot if single disc on sport bikes nor perimeter rotors.
