SBW#7 – Central Machinery Belt Sander Assembly and Review

Some time ago I purchased a Central Machinery 4″ x 36″ Belt and 6″ Disk Sander. For the longest time I had just clamped by 3″ wide portable belt sander upside down and used it like a stationary one but I found that as I used it with more projects I need a wider/longer table to do quality work.

As a result, I foray in this realm is with a bench top model from Harbor Freight. While I know most of the time their tools will not pass the longevity test, it made a good starter.

I unboxed it and started to assembly this unit and could already tell that would be the case.

One of the things I took notice of was the dust collection system on this device was not very robust. In fact, I am not sure how it even manages to work with a 1/2″ dust port on the disk sander dust guard definitely limits the cfm that you need to move dust. The port under the belt was better but certainly not what I was expecting. Perhaps this was designed to be hooked up to a small shopvac? I am not sure but my 4″ system could easily swallow the dust guards themselves.

The other thing that bothered me was the bed for the belt had a twist in it. It is one thing for the bed to be not square but with a twist in it, well, that will not necessarily make straight edges. I do believe though I can twist it back in shape but still I should not have to do that for a new piece of equipment.

Using the sander though was much nicer than my old setup. Even with the same grit sandpaper it seemed to easily take on the jobs I threw at it. Perhaps that is because the motor was just better than a portable one and therefore did not bog down as much. Plus, it comes with the added bonus of having lower decibels than my old portable Skill Belt Sander.

Overall, assembly was smooth minus some force needed to get the rubber feet on, overall stability is not great but good considering the price point. Longevity has yet to be determined. The two major downsides that I have found was the twist in the bed and dust collection – who needs one for a high dust creating device right?

SBW #6 – ReadyNAS NV Power Supply Replacement

What happens when you add high BTU electronic components with cramped IC design? You get a dead power supply. No, this is a not a duplicate post but it is essentially the same problem as my other post about a ReadyNAS 1100.

This is what happened to my ReadyNAS NV a couple of weeks ago when I had to have some electrical work done I had to have the power shut off for an extended time so I had to power the unit down. When it was okay to power things back up this device would not power back on.

So based on the response I was getting when I hit the power button I suspected that the power supply had failed since I have had this unit do this before. I opened up the case and took a look at the PSU and I could only see one swollen capacitor so yes, more than likely the PSU had failed. In either case, a swollen capacitor or capacitors are ticking time bombs with electronics.

Rather than purchase an overpriced OEM replacement I purchased an ATX power supply with nearly the same specifications. No, I’m not getting any money from linking the power supply but in the event anyone wanted to know what I used, there it is. I had read in some ReadyNAS forum posts on how to convert the ATX power supply to the same pin out that ReadyNAS used and  things looked good. To do swap the pins I used another reference on how to make a pin puller using paperclips. These were the same paper clips I used prior but I had to flatten them out a little more for this unit.

After swapping around the pins to match the ReadyNAS specifications I was able to power up the NAS.

Additionally because the new ATX power supply had a fan in it I had to use my hole saw to cut a hole in the back of the bottom of the NAS chassis which holds the PSU so the fan could exhaust air out the back. I figured this was a little better “design” than before as the OEM unit did not have a fan in the PSU. Keeping the fan also forced me to keep the new PSU’s top cover which did not have clips for the air shield to mount on so I had to use some silicon that had the ability to handle high temperatures.

The following video shows the process I used. Hopefully if someone is in the same boat as I was this video will help out.
