    Default new updaes

    Hi all, after a long long time I have a couple of new updates on my site: Bearing swap, Clausing compound slide adapter, and a power strip that I installed on the case.

    I should have some photos of my motorized X axis power feed next week.

    Anyone else have some work to post? This place has been pretty slow lately. Bloy, you still around? How about the other guy doing a ST overhaul? I love pictures.

    nice additions to your site! It's becoming (or has been for me) the "go-to" site!

    Hey thanks, I appreciate that. Did you loose interest in posting your progress? It would be neat to see what you have been up to.

    I've been working a new job and haven't really had any time for the ol shoptask. A pitty since it's running so well these days.

    Come on folks, any other pics of work or machine tuning? I need a fix.

    Thanks to all you guys here posting your mods and upgrades.

    My CNC kit came in from Dan 2 weeks ago and I'm slowly trying work out newly found bugs.
    My Z axis is now hanging up due to the tension from the belt, it's tight but not that tight.
    New pulley should be in today. Now I just need to find time.

    Hi Jason,

    I’m glad to see your site back up! Your work and documentation is really quite extraordinary.

    I have the older ShopTask Eldorado with a Quadralift. I purchased it with ball screws and have fitted it out for CNC work with Gecko drives and stepper motors. I’m getting ready to replace the spindle motor with a 180V DC motor. We will see how it works out.

    I am curious about how you resolved your problem with the step pulleys that you purchased from MSC. Did you find another source? Did you make your own? Please share the manufacturer, part number and purchasing source if your bought them. If you made them yourself, how about the specs or a drawing.

    Bob

    I found some good pulleys in an ebay store ("electricmotorsite"). They are not billet, but the finish is excellent and made in canada. I think the brand was Maska.

    My MSC pulleys (made by Browning) are in my junk box.

    Has anyone got a solution to this problem (besides a CNC conversion):
    The pitch on the X ballscrew allows only .0058"/rev feed rate with the lowest gearing available. I would like to see .003 for a better finish.

    Or this problem: My pictures are too big to upload. Any way to reduce their size?

    What about using a larger tool nose radius?

    Picasa is good for photos if you like free stuff

    Default Excellent Site

    I really appreciate the time and effort you've put into your site.
    I've watched it grow through the years (quietly) - and am very impressed.

    I have the same ShopTask you have.
    I had a lot of problems (still do) with the push-pull device for the downfeed on Z-axis (JT calls it a 'dog') - it gets stuch for me a lot and I just got tired of taking it apart.

    I have done no upgrades. Just used the machine for the small odd-jubs that ended up needing it.

    I plan on using your site to make all the necessary upgrades (ways & bearings & oil), as well as a few more (VFD)

    I'll let you know how it goes.

    Thanks,

    Bruce

    Hey guys,

    Thanks very much for the kind words. I need to get a couple more updates on there but my machine has been sitting in the crate for a few months since I just moved again. Man, what a pain.

    I recently motorized the X axis with a little gear motor mounted in the opening for the CNC servo/stepper. Only problem is it takes quite a bit of effort to turn it by hand now. I need to come up with some sort of quick connect contraption.

    Post some more photos people! I'm in need of inspiration. Maybe smallblock can post some pics of the patriot and that project he is talking about.

    Oh and happy chinese new year, hehehe. That works on so many levels.
