    I actually had to bother logging in to reply to this one.
    I'm super impressed with the amount of work you are putting in to this. I was hooked by the time you had done the OD mod.
    I love the whole theme, I can't wait to see this completed. One day I will have the time/money/space to make something this worthwhile...

    A question about your 'mill'. Is it a manual mill or a drill press with a sliding clamp bit?
    What is the difference?
    I have never owned any of these workshop tools but they make a huge difference to the quality of what people produce. The jigsaw and hand drill on my balcony don't quite cut it :D

    Once again, kick-ass workmanship. I'll keep watching this for sure.

    Thanks for bothering :thumb: I'm glad you like it so far.
    I use different mills, my own mill located in another town (can be seen in the first post of this thread) and two larger ones at university. All are manual mills and I use the ones that are available at the moment.

    Drill presses are not god at milling since they are only manufactured to withstand the vertical forces of drilling. Mills can withstand both vertical and horizontal forces and therfore produces a much better result when milling. The "sliding clamp bit" you refer to is a coordinate table or "x-y table". These are standard on mills and may exist on drill presses aswell but when used with a drill press their main usage is to get accurate distances between holes and not for miling slots that you can do on mills.


    Thanks for the nice comment :)

    Back again... with another update. After the Hd-blocks were done, I could countinue with the case itself. These parts are for supporting the top and bottom part of the case...and to get that round shape. It'l probably make more sense in the next uppdate when there will be some more parts added.

    Some 10mm Alu cut to a basic shape.

    Hate those nasty edges but, it's good theyr pretty easy to remove.

    I was needed to upgrade my tools with a set of 3mm needle files.

    The parts could not be completed in the mill alone and therfore I had to do the last shaping by hand, these red parts had to be removed since i needed a straight edge without a radius.

    I used a regular file to get that basic shape...

    then there were a copule of houres for me and the needle files to get to know each other... One almost done, 7 to go :S

    After some hours of filing and wetsanding all 8 sides where done. Was really hard not to mess up that radius but I think it turned out ok.

    They look extraordinairy. Great use of rotary table and more especially great use of files. You must have been really patient on this one.

    thx..about the photograpy. I only use one big sheat of white paper and one desktop lamp. I know two lamps would be better with a diffuser infront to soft out the light but I currently dont have that. Will try to make it in the near future. My camera is pretty crapy aswell. A regular pocket camera without any fancy lenses.

    Heres a quick tip on how to improve the photos. Since my camera is pretty crapy when it comes to contrast and the white balance. The pictures end up slightly dull and red toned. In photoshop there is a function called "auto levels" doin this improves most of the pictures and take like 2 sec to do. Heres a before and after "auto levels" shot.

    Thanks a lot. Yeah there was a lot of patience and sore fingers needed for these parts :)

    Great! I missed this project a lot. Once you get one side worked out, the others should seem easy.

    Woow, nice project, going to follow this one!

    I have a question, soon i'm building my own scratch build case. And i'm not sure what thickness I should use for the aluminium panels. I guess that 1mm is to thin for the side panels, what should i use?

    Thanks. Nice to hear you're starting your own build. I think 1mm for the panels will be a little bit thin. I would go for atleast 1,5mm (thats what I used for the case of the "Widescreen Projector)" . It kind of depends on how large your intending to make it, what kind of support there is, and if your going to have anything heavy mounted on it. In ProtoHype I will use 2mm for the sides since I will bolt some heavy watertanks on it and I think that thicker looks better.

    Thanks..maybe some day ther's a mill in your home aswell :)

    Thanks.. well, you've only missed the beginning. The realy fun part is just about to start :)

    Thanks for the photo-tip! I'm definately going to post process my shots for the next mod. Or even for the current one, I'm doing.

    I watched the Widescreen Projector too, very nice.. maybe I will use your brushing method in my project :)
    You are right about the 2mm plates, looks nicer too.
    Thanks for your help!

    Yeah, try it out. It can make a lot of difference to the photos

    thanks. If you use the brushing method. please let me know how it turned out. So far I havn't seen anyone else's results from the brushing method. Would love to do that.

    Okay first I have to apologize for my absence. I got a job offer that I couldn't refuse and therefore the protohype time has been suffering. The part of the build im currently in right now is the top and bottom of the case. This is one really timeconsuming and hard part of the build. Also most of the parts look the same which might result in less pics.

    Maybe you remember these 12 alubars, They need to be milled down in a step patern following a radius to make the sanding easier. Since I don't have acess to a cnc, I'll have to do it by hand :(. It might sound simple to just mill them down in straight steps and I thought that too. Well it turned out not to be that easy when you have 2 different vices. Pain in the ass to align them.

    Then it's time to mill the steps..

    Second one in the making, slightly different.

    Here I am testfitting the parts and realized that those steps are probably to large. Will take a long time to sand them down by hand and I risk loosing the shape. Will have to make smaller steps..

    ..like these ones.

    Now thats better. But the part in the middle is 1mm to high And I will need to mill that of the bottom, because this hurts my eyez.

    Here you can get a glimpse of what the finished top will look like. The bars need to be cut to the right lenght, the one that's shorter is already cut...duh

    Now I'll just have to do this all over again for the bottom pieces.:sigh: I so hope the finished result will meet my expectations.
    See ya.

    Nice work you really are making amazing shape. You will have lot of sanding for sure but I can't see how the finished result will disapoint you when I see how awesome it is right now.
