Join me in this second instalment as I mount the VFD unit and program it along with finally testing the machine out for the first time. If you stick around to the end you might be amazed at the tolerances I manage to achieve.

Nice job. I like how you are right to the point with the step by step process. I would personally like more video of the finished cleaning before assembly just so I could see how a 100 years old machine stood up against use. I would love to undertake a project like this. It looks like it was in fairly good shape when you got it. Cheers
Glad you enjoyed the video and enjoyed the way I presented. Yeah I was lucky that the machine was in fairly good condition, it had been a machine I’ve been wanting in the shop for some time now so glad I now have one.
Nice job Joe. I have a two suggestions. Replace the table feed handle with a handled wheel as a modern grinder has, and grind the magnetic chuck flat. I would bet you will get even better results.
Yeah that’s a good idea Joe, I’ve seen those style of hand wheels and did think they look easier. Maybe could be a project for a future video. All the best.

Great rebuild a few things that might improve things and I’m sure others have commented. 1. Dress the mag chuck with the wheel freshly dressed that will give you the best accuracy 2. Never look end on to a grinding wheel particularly when you are starting one up. And 3. The inverter or VFD you are using will have a EStop function so it would be good to fit one on the front. Other than that great machine and another cracking video.
All the best,
Jon.
Excellent tolerances'!
Hey, controls guy here. You’re doing good work. That plate looks nice and sturdy. You might want to just use a low cost back plate for a while until you get the location sorted out. You might be tempted or maybe an e-stop or something to add some kind of remote gateway for various reasons..
Once you have that down, then mill something really nice like you did.
Also, check if there’s any minimum rpm or frequency on your equipment. For example, pumps often say they shouldn’t be run below 36hz. (60% of max RPM). It may be the case for the wheel, the motor, whatever is transferring energy.
The point is that it will protect your equipment and make it last longer if you set your vfd to never run below that speed.
Other than that, I wouldn’t suppose to pretend what your equipment needs. You look super skilled.
Mist cooler of flush cooler wouldn't hurt for surface finish too
Thanks. Very useful. Cheers
Glad the video was useful
Thanks Joe....I enjoy all your video's... Keep them coming.
I have to agree with Joe on how to improve your SG.
If you do, then I would love to see a video showing the improved results.....Happy grinding.👍
As said below, you need to cover those live terminals , there are index of protection issues there Joe! Nice job getting it back up and running!👍
Nice Job mate you need to grind the mag chuck but don't take such wide passes as the wheel speed is slowing down and you can get surface cracks from the heat generated
Good job, its an old machine so you will get a few undesirable marks on it. try to get your cross travel at 2/3rds wheel width to keep the wear in the middle 🙂
Good job, from a safety point of view I think that you need the enclose the cables to the terminals as they are only single insulated at that point, your collection box need to be a little higher as particles are going over the top, an extractor fan system would help and lastly to wear a mask would be a good idea. Very envious of you having one, I am sure that many others would like one as well.
Lovely machine and an interesting video. It will be interesting to see whether the accuracy holds up over a larger area and length. Regards.
Yeah completely agree George will be interesting when it comes to a longer part what tolerance it can keep.
Maybe add shop vacuum cleaner atrachment to collect flying dust while working. This dust is really bad for all machines
Yeah a proper system would be great. For now I’m using an old Henry hoover seems to do ok for now.
Nice old machine that Joe, 100 years old and fitted VFD 3 phase to single and it run's like new I was just thinking that each phase pulls about 3 amps do you run it off 13 amp plug or dose it uses it's own 15/16 amp supply Great video take care mate🙂🔨🔧🪛
Hi Shaun glad you enjoyed the video, so currently running off of a 13A fused plug. If during the colder months I find it blows the fuse then will have to up it to a 16A commando plug.
@@MachiningwithJoe Hi Joe It must be a high start up needs to draw more amps ,when running the amps will drop I the winter it dose take that little bit more power to start mate
"what a lovely surface finish that is" Sorry, but it's not a great finish. As you do more grinding, you'll begin to see the defects. I think most of the problem here is aggressive cuts and large step over. Don't worry, you'll figure it out. Neat little machine.
