  1. Here is another option for desktop mills.

    mill.jpg.e4033ccebf73ef4909aae431014abaa3.jpg

    It is from a UK company Warco http://www.warco.co.uk/milling-machines/32-wm-16-variable-speed-milling-machine.html

    They offer a big range of sizes and functionality as well as a host of tooling and other options plus very competitive prices.

     

    I offer up this because I have just bought the one shown, just waiting for delivery, very excited.

  2. Hi hjx

     

    Thanks for the comments.

    Rigidity is certainly an important factor especially to achieve a decent accuracy.

    But these are not milling machines so I would only expect to be taking light cuts.

    That is why I hope to evaluate our work one, so far it looks good, but it has not been challenged, it's mostly used for foam cutting.

    I don't think I have a great need for a fourth axis.

    That would be useful for rotating the work piece whilst machining, like turning.

    But I can handle that on a lathe.

    Being able to approach the work with the spindle at an angle is not something I think I need.

    But I will update this subject as I move further forward.

     

    Thanks

  3. I have let the subject of a new tool rest for a bit but I'm picking it back up now.

    Part of the reason is that we recently got one at my workplace.

    It is a different type of design to the ones I was looking at, but more suitable for the things I need it for.

    Most relevant is that the type I am now considering use a commercially available router for the cutting spindle (Dewalt or Makita)

    That then comes with a 1/4 chuck so is a lot more flexible with regard to tools it will accept and is also made to specifically resist some side loading.

    So is capable of milling in wood across 3 axis.

     

    This is the design I am considering, and is the one we have at work, there are a couple of alternative suppliers:

    Router2.jpg.ccc16a3024104a85e6dc5b295404d708.jpg

    Prices are more but still keeping me interested.

    This type including router, milling kit, controller and software is circa £1300 for 750mm x 500mm bed with 140mm Z axis.

    I intend to get to know the one at work a little first then probably go for it.

    The other thing that I like is that the ones I am looking at are UK or US made.

    The two that look best to me are

  4. Hi Jim

     

    Sorry I missed your reply a while ago.

    But thanks for the picture.

    I should recognise it certainly, I worked for a while in Priddy's Hard, Gosport side as you say 'at the back' of Portsmouth Harbour.

    My window looked out directly onto the redundant ships, up for sale or waiting scrap, mostly RFA's and the like.

    Certainly brightened our day when the SBS used them to train in ship assaults, air-borne and sea-borne.

    Also the Vanguard trying to get a last pint in the Still & West reminds me of the photo still hanging in the pub.

     

    I'm still enjoying seeing your work immensely, and your work rate is staggering.

     

    all the best

  5. A few days ago I visited a trade fair for 3D printing / Additive Manufacturing as part of my day job.

    I noticed a great little filament machine that was boasting multiple interchangeable heads.

    That included a router head and a laser cutter head as well as a few different printing heads.

    The laser was limited to paper and card really but the router head was cutting and carving some pretty nice details in wood to about an inch depth.

     

  6. Hi zappto

    While you are designing and making your base board it would be a good time to consider a couple of things so that you can incorporate some features.

    You will want to mount your bulkheads nice and square to the spine and the base so maybe think about features to locate a jig to held hold them square.

    Also you might want to be attaching things to the model later in the build, so some feature to hook or attach clamps, elastic bands etc might be helpful, could just be a simple lip along the edges.

  7. Hi All

     

    I have been getting very interested in these little machines recently.

    Only really for fine wood milling.

    You see a lot of them across ebay and Amazon, pretty much all of the home market ones seem to come from China.

    They are three axis, USB linked, approx. A4 table size and come with a software package.

    And the prices are very good.

    But that is as far as I have got, in a lot of respects they seem too good to be true.

    Has anybody got any experience of using one?

    Or even seen one in action.

    I would like to understand a lot more - build quality, spares availability, ease of programming, reliability etc etc

  8. For models created in SolidWorks there is very good, free viewer - eDrawings.

    You get pretty much full 3D viewing functionality - pull apart assemblies, section, measure, rotate, zoom etc.

    Visit the solidWorks web site to download a copy.

    It will also view some other formats like ACAD.

    You can use it to view native Solidworks files, or the creator can save a native file as an eDrawing file to help protect their IP.

  9. Hi Graham

     

    I have recently done just that (see confed log)

    I used Admiralty Dull Black, I thinned it with water, probably about 50/50 but thinned it to a water-like consistency whilst retaining some degree of colour.

    I then sprayed many coats, many coats! about 20 in all.

    If you do very light coats, which is a must to avoid runs then they dry in less than an hour, at least enough to do a further coat.

     

    But as I mentioned in my log I am leaning towards a brush rather than an air brush in future.

    The multiple tinned coats works pretty well when brushing and using the gun is a lot of extra faff.

     

    Best of luck
