This old but good DeWalt angle grinder starting cutting out while making that gate today.
Noticed it was whenever the cable moved, so it was just a broken wire. Easy fix.
Wire a bit shorter now, new ferrules crimped on and runs fine again. The brushes still have enough life left on them, too.
@Maker_of_Things @mcSlibinas @Workshopshed @domasla Regular thread. Just needed coffee ;-)
(and time for the leggo spray to creep in)
Then Mr. Angle Sharpener got to work, because this blade was beyond anything a little stroking with a whetstone could fix.
Cuts properly again. The wheel drive doesn't engage, but then I don't use that anyways so it's not high on the to-fix list.
Looks like I already put new oil in the motor last year 👍
DIY Semi Auto Grinder Builds Itself (Sort Of)
[JSK-koubou] is no stranger to making tools to improve their work, and this latest video is yet another in a long list of such builds, just checkout their YT channel to see the many other examples. The tool being highlighted this time is a semi-automatic grinder (Video, embedded below) which could be very handy in many situations.
Many of us struggle a little to get straight cuts with an angle grinder, especially with softer materials, as it is sometimes hard to get a good 'feel' of how the cut is proceeding. Once the cut is started, thin blades will tend to 'track' in the slot, so if it starts off a little bit, the whole cut will be off. Most annoying. Anything to help keep things straight and square would help a lot, with the extra feature of a motorized drive enabling a constant cut rate, and presumably giving an increase in the cut quality.
Using the part completed rig to cut its own leadscrew
Since operation is hands-off, you could set it up, and leave it to do its thing, whilst you step aside, away from flying sparks, noise and the remote possibility of getting a splintered blade in your face, should the unthinkable happen. All good things.
The detailed build video shows what looks like a pretty solid construction, there are plans available on the accompanying website, but they do request a small donation of ¥1000 (less than $10 USD) to download them. Given the usefulness of the tool, this seems like a small price to pay. We quite liked some sections of the build video, where the tool is used to cut its own components, as it is built-up sequentially. Clever stuff! Another interesting technique to see was the use of a flame-heated (Stanley) knife blade as a drive belt end-jointer. Somewhat tough on the blade, but it's a consumable item and gets the job done, so that's good enough for us!
Parts wise, there's nothing special at all here, with most easily sourced via the usual mechanical suppliers, but we reckon you'd be able to find most of it on eBay as well. We think this is exactly the sort of build that would work well in your local Makerspace, so perhaps give that a thought?
Bored with manually cutting off? Need an overkill solution for a mundane job? How about an Automatic Cut-Off Saw? If you need some defense against the mighty angle grinder, then perhaps Proteus is just the ticket?
Thanks [Keith] for the tip!
