One guy said Griz wouldn't replace it and after he sent it back, they refused to sell him another. Don't know what to make of that, but I've always heard that with any of these Chicom tools you may be buying much more of a kit than you imagine. <br /><br />I'd be willing to pay more for someone to do a higher level of QC and not let mills like that get shipped. Jet? Precision Matthews? Don't know.<br />SiGraybeardhttps://www.blogger.com/profile/00280583031339062059noreply@blogger.comtag:blogger.com,1999:blog-1592992209402300549.post-40917723103440182462014-09-20T20:12:13.939-04:002014-09-20T20:12:13.939-04:00Hooray for flat floors and wide doors!

Definitely worth the $300 extra for the $1200 G0704 over the $900 LMS X2.<br /><br />The G0704 has a large following, with a clear path to a future CNC conversion. See www.g0704.com for a great resource by Hoss Machine. There is an epic 485 page thread on CNCZone on the G0704 by Hoss 2006.Anonymousnoreply@blogger.comtag:blogger.com,1999:blog-1592992209402300549.post-58936966065547355472014-09-20T13:43:28.556-04:002014-09-20T13:43:28.556-04:00It's good to see progress continuing at the sh...It's good to see progress continuing at the shop. I'll agree with ASICDude, consider CNC before you buy, either as a retrofit or out of the box. While it is possible to DIY CNC, it is an extra bit of grief someone with a day job probably doesn't need. <br /><br />Seig - I've heard major complaints about quality, particularly castings. Many of the Chinese tools are described as kits; some modification required. <br /><br />Grizzly has a good reputation, and I've considered one of their tools myself. I've also heard good things about Rong Fu. I've done a lot of business with LMS for tooling and the like, almost always happily, but never for tools. My expectation is they charge a bit more for additional handholding (or at least reference material) and in my case worth it. <br /><br />I tend to agree with the Chris' Tips on the LMS 3990 - a tilting base isn't really a feature (for most hobbyists). I own a Taig micromill with a tilting base and wish it didn't. You can probably accomplish the same thing with a tilting vise albeit at the expense of some work envelope. Tramming accessories are available, so if you get a tilting base include those accessories in the Out The Door cost. <br /><br />I like your R8 spindle choice, it is a heftier spindle than mine. Here's the weird part of mills. Eventually you'll probably spend more on tooling and accessories than on the tool itself. So I'd concentrate on selecting the capability of tooling before the tool itself. There may be other spindles that are more appropriate for what you have in mind. Or maybe you don't have anything particular in mind. Just fun stuff to play with. <br /><br />Please take my comments with a grain of salt. I've not done much with my mill, and it's been a while since I even paid attention to the market. <br /><br />There are some good forums out there where people will have a lot of good advice to offer. Worht looking into. Even better would be to find a local hobbyist machinist club and attend at least a couple meetings before you buy. Maybe you'll even find a mentor there. <br /><br />Good luck and 73, JimAnonymousnoreply@blogger.comtag:blogger.com,1999:blog-1592992209402300549.post-46306009395559914892014-09-20T12:45:44.893-04:002014-09-20T12:45:44.893-04:00Good discussion on mills.

Sometimes there's value in getting the machine ready-built with CNC, other times you get better value and higher precision doing it yourself.<br /><br />I'm in the market for a smaller-ish CNC mill so I'm watching with avid interest and not a small amount of shop envy!<br /><br />Thanks for the detailed writeups!<br /><br />ASICDudenoreply@blogger.comtag:blogger.com,1999:blog-1592992209402300549.post-66415431753158831112014-09-20T11:43:29.000-04:002014-09-20T11:43:29.000-04:00Eric, if I can find a Bridgeport for a reasonable ...Eric, if I can find a Bridgeport for a reasonable price, it's a really strong possibility. That "if" ends up being a bit of an issue. <br /><br />There are many machine shops in this area and one thing about Bridgeports (and a lot of other machine tools) is that with a bit of care, they'll last a long, long time. Which brings up the other issue: I'm not sure I can tell if one has had adequate care and isn't two tons worth of problems. <br /><br />And Jim, one thing I <b>don't</b> have to consider is stairs! It's Florida flat here. I designed the shop with double doors to allow big things to be rolled in. Just have to clear the way to the double doors. <br /><br />SiGraybeardhttps://www.blogger.com/profile/00280583031339062059noreply@blogger.comtag:blogger.com,1999:blog-1592992209402300549.post-51237769747895013952014-09-20T01:24:38.584-04:002014-09-20T01:24:38.584-04:00One of my neighbors back in Illinois had a full-si...One of my neighbors back in Illinois had a full-size Bridgeport in his basement.<br /><br />My Dad worked for the company that had the franchise in the Chicago area, and sold it to him.<br /><br />The delivery included setup, and my d\Dad said the delivery guys said some things he'd never even heard in the Navy getting it down the stairs!drjimhttps://www.blogger.com/profile/05647484115197408897noreply@blogger.comtag:blogger.com,1999:blog-1592992209402300549.post-30601278121718205842014-09-19T23:05:23.941-04:002014-09-19T23:05:23.941-04:00Surely you need a Bridgeport!
