Hackintosh Update

Posted in Technical on August 9th, 2009 by tdorcas

After a week of different installs and frustrations, I finally got my Hackintosh upgraded to 10.5.7 with Quartz Extreme (QE) working. My graphics card is a Nvidia GeForce 8400GS with 256MB.

Essentially I followed the instructions below to upgrade to 10.5.7. I then added the appropriate EFI string using OSx86 Tools, removed NVinject and NVEnabler 0.1 kexts, repaired permissions, and cleared the extensions cache. When I rebooted, everything was working (finally)!

Busy Week

Posted in Technical on July 27th, 2009 by tdorcas

Whenever one computer breaks down in the house, they all seem to breakdown. My primary PC is starting to freeze (I’m thinking it’s the video card). While updating my Mac to 10.5.6, the hard drive crashed. And my primary Web server (CentOS 4 running Apache in a VM) decided it didn’t want to connect to the database any more and therefore stopped servicing up pages. Yuck!

The biggest issue was the web server as I host a couple of websites for friends. Over the last couple of months I’ve been trying to build a new Virtual Machine to host my websites. The old VM was a server that I P2V’ed last year running CentOS 4. That server got to a point where I could no longer do security or application updates so that server was very vulnerable. It was also 40 GB in size which honestly it didn’t need to be. As I mentioned, for the last couple of months I have been building and testing a new web server based on the latest versions of LAMP (Linux - CentOS 5, Apache - 2.23, MySQL - 5.0.43, PHP). For the most part I had everything working so when the old server decided to quit, it was a fairly seamless process (although a bit time consuming) to move over the different websites and import the databases into MySQL. It did take me another day to properly configure Apache to serve out the different websites. The last major project is migrate the Gallery2 portion of this website that hosts my picture gallery. So as of last week, we are on a new, updated server. That’s one thing down. Longer term I would like to rebuild the physical server that VMWare sits on as the OS itself has become a bit flaky.

This past weekend I started upgrading my Mac so that I could take advantage of the latest version of iLife. Just as I was finishing the upgrade to 10.5.6, my hard drive crashed. Off to Memory Express I went to get a 1TB SATA drive and because it was so cheap, another 2 GB of RAM. The last time I built this machine, it literally took weeks to get everything working correctly. This time by end of the evening I had upgraded the machine to 10.5.6 and the only thing that was not working was Quartz Extreme. Hopefully I can find the combination of drivers to get this going soon. I have to say that with the new hard drive and more memory this machine feels quite a more snappy. It kind of makes me want to put in a Solid State Drive and see how much faster things work.

So with that done, that only leaves my primary PC. I’m hoping to get another video card and pray that’s what’s causing the issue.

As much as this stuff can be a pain in the butt, it does feel good when I get it working.

Craftex CT128 Lathe vs. Nova 1624

Posted in Technical, Woodworking on July 3rd, 2009 by tdorcas

I have had my Nova 1624 Lathe for a almost 6 months. It is a quality machine. However as easy as it is to do, I hate changing the belt to change speeds and a small vibration has creeped into it that I cannot seem to get rid of. I have replaced the belt, made sure it’s level relative the floor of my garage and have even tried different chucks to no avail. Maybe it’s time to start thinking about a new, more powerful lathe. Something with variable speed, larger capacity, more horsepower, and something that will quench my lust for bigger and better.

I initially thought I had a great deal on a Powermatic 3560b. It turned out to be not true. At the same time I started reexamining the Busybee’s Craftex CT128. Essentially this is a rebranded Laguna Platinum Series 18/47 Lathe. In the past I have used a Laguna 18″ Bandsaw. It’s awesome. Quality really shines through and the accuracy of the cuts was great. When I was thinking about getting a new lathe back in November this was on the short list but the price was bit more and I needed to put in a 220v circuit so the Nova won. Considering it had many of the same features of the Powermatic, the price has since been reduced by $300, and I didn’t mind putting in a new circuit, the Craftex CT128 was back on the board.

I have to say from a customer service point of view, my experience could not have been better. Since I did not have my truck, I needed to take apart the box at the store. The manufacturer really had everything locked down to make sure nothing shifted in transport. Once in the Jeep I headed home with my new purchase. It would have been nice if I could have just brought it home, put it together and started turning. That was not to be the case as I already didn’t have any space in my shop.

In order to make this work, I ended up taking out my first workbench which was a feat by itself. I had lots of stuff stored on, in and under it. I then struggled to move my new workbench where the old one lived. With that done and a little (or maybe a lot) of cleaning, I was finally able to start moving all of the components into the shop. While everything was heavy, I was able to manage things reasonably well. it took about an hour and half to put everything together including cleaning the lathe off.

It’s at this time that you really start to take notice of the build quality of the lathe and honestly I was a little disappointed. Despite tightening the handwheel there is still a lot of play in the tailstock and the handwheel feels cheap. The outside casting of the banjo was rough and I had to play with it for a little bit to make sure that it would adequately tighten. The tool rest was also not to my liking. In it’s current configuration it would be really hard to do to pull cuts. If anything it’s pushing the gouge away.The tool rest on my Nova is actually one of the better tool rests that I have seen. Well, no problem, I’ll just use the tool rest from my Nova. Wait. The hole is too small. In fact none of my extra tool rests fit. I wasn’t too happy about that. In the end I retrofitted my whole tool rest from my Nova onto the Craftex. It’s fairly finicky but so far it is working. If the hole were just a bit bigger that would have been great.

The headstock is another area of concern. On the Nova, there is a simple spindle lock. Pull out knob, turn upwards, and then it automatically lock the spindle. On the Craftex there are four holes on the headstock. Three holes are for indexing and the third is the spindle lock. My main problem is if you use the spindle lock it’s either in or you have to take it out. There is a really good chance to loose it while working. Plus it’s a bit of a pain to get out if you actually use it for indexing. I actually had to grab pliers once to unscrew it. In addition there is no handwheel and it looks like a bit of work to add one. Also after using a 4 prong Spur Center for a large bowl blank, I could not get it out with just the knock out tool. I actually needed a hammer to get it out. Lastly, despite my best efforts, I still have yet to be able to get everything perfectly level so it doesn’t take much speed to get it walking about the shop (On my Nova, it only did this once when I set the belt too high on a large unbalanced bowl blank).

So how does this compare with my Nova? With the exception of the variable speed and a bit more capacity both in swing and distance between centers, the Nova is a better lathe. The fit and finish is top notch through out. Since they are side by side in the shop it becomes obvious the choices each manufacturer took in building their lathes and now that I have something to compare it to, I really think Teknatool made all of the right decisions.

Let me say this….For a $1000 I recognize that there will be some compromises. I think had I not been turning for awhile most of this would have gone over my head. The Craftex does have the things that I wanted - Larger capacity and Variable Speed (The verdict is still out about power. I was able to easily stall it in the high speed range. I have since move the belt to low speed for more torque.). Despite the issues I have expressed, you do get a lot of lathe for the money. However as someone who is really focused on turning, the smaller details have me worried. I really don’t want to buy another lathe and then have to get another one in a year. While the Powermatic is thousands of dollars more, I am seriously considering spending the money to get one.

I know there are lots of people who have this so I would be interested in knowing their thoughts.
