  • Why did you put that subtitle shit right in the way of the view??

  • @kingmike40

    Don't buy Birmingham. They are horrible.

  • I just got the 12x36 harbor freight- identical part for part with grizzly and shop fox(and others). Retail $1999 and with the Easter coupon $1500. With freight and tax $1706 to my curb. I had no problem keeping within .001" with the smithy 12x20. I guess farm machinist is making parts for space x. For the price, you can't beat the "chinese junk" . It's a global economy now and paying more just to buy american actually hurts "our" economy.

  • I have the 1642 Grizzly lathe and a Southbend...

    I'm very happy with both...

  • @FarmMachinist

    well why did you buy a cheep lathe? ask hoss at hoss machine what he can do with a grizz.....mabe your just a bad machinist? hsm had a artical about referb southbends....if i had 12,000 it would rock. or 7 or 8 g's for a nice rebuilt bridgeport.

  • They both sell cheap chinese stuff. From what I hear though, Grizzly has higher QC standards than the other companies selling the same stuff.

  • If you like producing sub-par parts ... then by all means buy a Grizzly or some other cheap Chinese piece of crap.

    Here's another example ... my lathe's spindle through tube of so out of wack that I can't use the $300 collet closer I bought for it because it will bounce the lathe across the shop floor ... again ... according to Grizzly ... it's within spec.

    If I knew then what I know now ... I would've bought a refurbished South Bend lathe and Bridgeport mill instead of Grizzly's junk.

  • Buy American ... Grizzly tends to sell cheaply made Chinese junk ... I have a mill and lathe and both have issues and have trouble holding high precision tolerances on parts. I wish I'd spent the extra money on a quality machine now instead of trying to a save some money.

    Grizzly's tolerances are a freaking joking ... my milling machine for example ... it's table has 0.004" run-out across the surface (warped on one end) but according to Grizzly it's within spec ... lol.

  • Grizzly has great customer service and technicians to help you out if you run into a problem ... main reason I went with a Grizzly.

  • I was shopping for a lathe and I was looking at grizzly and comparing it to birmingham lathe. I noticed that the two machines are Identical. The birmingham is less expensive. Any opinions on which is better.
