    Yet again it’s been a while since the last update because I’ve been debating what the best way forward is (read being indecisive for debating). As I mentioned in the last entry the bolting together plan was working, mostly, but it was very time consuming and didn’t offer the advantages I’d hoped for. If I…

    I’ve not managed to get much done over the last few days as work has been getting in the way, I suppose I need to do something to pay for all this CNC equipment though. I’ve got all of the brackets for one side drilled and fitted now but I’m starting to wonder whether I’d…

    If you have been following this build you’ll know that I’m new to engineering so this may or may not be the best way to go about the task of fitting a bracket but what I can say is that it works. Since all the brackets are the same size and have the same hole…

    It’s been a while since the last update, I’d like to say that’s because I’ve been busy building the CNC but the truth is that I only got a few days to work on. I’ve made a good start on the frame though so I thought it was time to do an update.

    Well I’ve found my new favourite paint in CombiColor. It goes on smoothly with very little odour and the coverage is pretty good considering it’s yellow which doesn’t tend to cover very well. That lot you see in the picture below was covered using <100ml of paint. It needs another coat but the 2 litre…

    Before I piled into drilling holes in the actual steel that will make the frame I thought it was best to do a dry run with some of the off-cuts that I have. I’m really glad I decided to do this as it has shown me that I’ve got some accuracy issues that I need…

    The big clean up continued over the last few days. I was beginning to think that perhaps this coating on the steel should be left in place and that was confirmed by someone on the CNC forum. It seems steel comes with a protective coating. My problem with that is it holds onto the oil…

    The last few days have been devoted to the steel for the base. Someone I met through the CNC forum offered to source and cut the steel for me which has saved me a big job and I collected the parts last weekend. After leaving them in the hall for a week I carried them…

    Before I got all carried away and did something all unnecessary, like spend money, I thought I should try hand routing some aluminium. The compound table is only £100 but that’s £100 I wouldn’t have to spend on something else in the build which is already costing too much anyway – why do I always…

    For the last few days I’ve mostly just been doing research into how I’ll actually build the frame and the rest of the machine. I found a really cheap welder (stock clearance) which I almost bought but I’m glad I didn’t now. As I mentioned in the last update I decided to weld some of…

    I’ve been doing quite a bit of reading of build logs in the last week and a some tinkering in sketchup to try and improve the design. One of the things that I constantly read people being advised to do is beef up the connection between the gantry and the x-axis ball screw. It’s very…

    I’ve been adding a bit to the design over the last day or two but I’ve been struggling a little with the diagrams provided by Chai (linearmotionbearings2008 on eBay). They look like scans of scans of badly taken photos and are only just readable if you squint. I thought, therefore, I’d try and track down…

    Now that I’ve redesigned the frame it’s time to start adding bolts to the drawing to find out whether I can actually hold everything together. It might seem a little superfluous to add every single bolt but there’s a couple of good reasons to do it.

    No matter how much I tried to convince myself otherwise I just wasn’t happy with the design of the frame. Having the legs on the inside of the frame just felt an accident waiting to happen so I bit the bullet and reworked the frame to give it a more conventional design.

    I was reading this build thread yesterday realised I was trying to rush this project and that something was going to go wrong if I didn’t slow down, do a bit more homework and spend longer on the design. I really wanted to get this done in the time I have off but it looks like that…
