New Grizzly or Used Bridgeport Mill?

g0484.jpg


That mill weighs about 1000 LBS and costs about $1800.

I don't know for certain, because I've never used that mill, but I'd bet the Bridgeport will have better bearings, better balanced components, and I'm about certain better basic construction. And it will weigh twice as much. So I'm pretty sure it will give a better finish and take heavier and more accurate cuts.

A good used Bridgeport works really well. For that money you should be able to get a good used one. Listen to the spindle, look at the ways, perhaps look up a website that tells you how to use an indicator to look for slop and other issues. But assuming you got a good Bridgeport, I'm pretty sure that would be a better choice. But again, I've never used that little bed mill there, so I don't know for sure.

Being a hack, I've bought a lot of used equipment over the years. I did buy a 12" Enco lathe new, having had a bad experience with a used Southbend before. The new lathe had hardened and ground ways, spindle bearings rather than babbit (which was part of the problem on the old SB) and was shiny and new. That was years ago. A clapped out old Bridgeport I had at that time is still running strong. That new lathe, with probably less than 200 hours on it, is now leaking oil everywhere and the electricals are flaking out. Roughest piece of equipment in the shop. It cuts okay, which is more than I can say for a 13" harbor freight special I've used...

Good old equipment is good....
 
I have a grizzly milldrill, and have used ancient badly maintained bridgeports. if you dont want the bridgeport give it to me :D
seriously,grizzly makes an ok chi-com piece of equipment, but a new grizzly small mill-drill will never be as strong or rigid as 2000 pounds of properly seasoned connecticut cast iron
go bridgeport
just my opinion

Is there a website or book or something that will show you what to look for and how to tell if the mill is any good. I have seen a LOT of Bridgeport Mills that look like they are ready for the dump. I don't care about the looks but don't want to spend thousands for one that is wore out. Is it hard or expensive to rebuild one?
 
i would take an old bridgeport and fix it up compared to buying a new made in china machine. you need to check for play in the spindle bearings with an indicator. also check the trueness of the table on both asis.
 
Old Bridgeport for sure.
Just be sure it's in OK shape (it can be ugly, but you want good ways). If you need to, bring someone with to check it out, but it's worth the extra trouble.
A couple years into it your Grizzly will be worth $500 and the old Bridgeport will still be worth 2K or more.
 
I wish that I lived closer to you. I used to scrape in the ways on machine tools. If you learn how to scrape in the ways, you can make it like a new machine. It's not that hard, but it is very time consuming. If you buy a used bridgeport and want to redo the ways on it, give me a call and I'll give you some pointers, tips, etc. on how to get them reconditioned and back into like new shape.

Scott, I have an old Burke horizontal mill that is in serious need of way rework, how is the scraping done ?

Here is my take on it. The bridgeport is the better machine if it is in decent shape. But, my question is how much room do you have, do you have 3 phase and what are you planning to make? For guards and minor pieces you will be ok with the Grizzly. If you have room and a single phase Bridge port or 3 phase go that route
 
I went through this same issue a couple of years ago. I wanted a bridgeport, and had a couple located. They were each in the $3,500 range, Then the issues of 3-phase power, a converter, space, and moving the machine came into play. Taking it all into consideration, I chose to go with the Grizzly.... http://www.grizzly.com/products/Vertical-Mill/G3616

As has been said, its not a bridgeport, but it has done everything I have required of it, including running a 2 1/2" face mill for milling mosaic billets, and creating a number of replacement parts for other machines in the shop. I do admit that I wish it had a longer table, but at the time the cost was $2,730, which included the freight. I had it dropped off at a nearby business, and did have to rent a small forklift for an hour to get it to the shop and inside, but that was only $45.

Take all of the factors that affect you into consideration, and if you can meet all the requirements, get the bridgeport, but be realistic, and think it out. If you can't get power to it, or don't have the room for it, its gona be an expensive yard ornament.
 
I love my new Industrial Hobbies Mill.Check their site out.Bridgeport capabilities in a smaller 1300lbs package.
 
The IH mill and the grizzly mill in the picture are of one design - so called RF 45 (Rong Fu 45) clones. IH has larger work envelope .

For many of us a Bport, while affordable financially, is a no-go due to space limitations, so we have to look @ bench mills. Unlike the lathes, where one can get old American benchtop lathes, no such thing exists for benchtop mills.

And when one considers benchtops, there're no alternatives but to look at stuff with "Made in China" labels.

Choices are numerous, but boil down to :

- Sieg X2 (aka mini-mill)
- Sieg X3 or Super X3
- RF 45 clones

For a good review of first 2, visit mini-lathe.com . For 3rd, go to industrialhobbies.com

X3 and RF clones will have all power a knifemaker will ever need.
 
There's some good and bad advice in this thread, but for the moment, your situation boils down to used American or new Import.

I faced the same thing about five years ago, with the additional modifier of being in Alaska. Due to shipping distances and weight, there's relatively few machine tools up here, but with a fairly high ratio of do-it-yourselfers and ex-oilfield types, what few there are are in fairly high demand.

Finding a local mill, then, was a simple binary issue: It'd either be cheap, but worn to junk, or it'd be in good condition and priced appropriately. 'Appropriate' meaning about what a new import costs for a similar machine.

I would have very much preferred a Bridgeport or equivalent "name brand", such as Lagun or older Rockwell or Millrite. But I'd have had to buy it sight-unseen, based largely on lo-res digital photos and the word of the seller. eBay is chock-full of machine-tool sellers that slap on a coat of fresh paint and even run a power scraper/flaker over the ways to make it look unworn, and then ask premium prices.

With a mag base and a dial indicator, I could find the wear and determine the condition, if I were there in person, but the travel to do so would have cost $1,000 to $1,200 including renting a car and a night or two in a hotel. That's not bad if I were buying a $50,000 CNC, but pretty steep for a $2,000 Bridgeport.

And, of course, what if it turns out that machine is crap? I've just spent a grand for a two-day vacation. :D

Bottom line is, I do NOT recommend buying a used machine tool sight-unseen. If I can see it, indicate it, start it, crank some handles, maybe even make a few chips, then yes, I'd by far rather have a good American over even the best Import. But if you can't try it, it's buying a pig in a poke.

I eventually went with a full-size Grizzly Bridgeport clone. It appears they don't carry this exact model anymore (G4037) but it was made in Taiwan rather than mainland China, it's very good quality, and I've had basically zero problems after five years of moderate, but almost constant, use.

The smaller benchtop mills are of course not as good- they're not as powerful, not as rigid, don't have some of the features. The Chinese stuff (as opposed to the Taiwanese) is just not quite up to the same build quality.

But, they're still very capable machines when you work within their limitations, and after seeing how many people on this board think it's A-okay to mill "just a little bit" with a Harbor Freight drill press and a cheap import X/Y table, you'll be miles ahead of them. :D

And as noted above, there's basically no American equivalent to a benchtop mill. There's a rare few out there, like the little Deckel with a vertical head, or the Millrite that's damn near a half-size Bridgeport, but you're again looking at a used machine with fifty years of questionable maintnance on it, plus the competition of all the other home-shop guys that also want the smaller machines that fit in a garage or basement.

And thanks to that demand, the worn-out small American machine is going to cost more than a roughly-equivalent import.

All that said, don't worry too much about buying an import just because it's an import. Buy from a good name brand, like Grizzly or Jet, rather than Harbor Freight or Northern Hydraulics. Grizzly actually stocks repair parts, has a very good warranty service, and their techs actually know what they're doing.

The other secret to imports is that they virtually all come out of the same factory. Jet just has theirs sprayed white, Grizzly paints theirs green, Harbor Freight uses red, and so on. BUT... the better sellers, Grizzly especially, get the "cream of the crop"- they require, and pay for, better fitting, higher class bearings, more finishing, more attention to detail.

The parts that don't pass muster for Griz and Jet get used for, say, Sieg machines. Parts that aren't good enough for Sieg get used in Encos, Enco leftovers get used in Harbor Freight. (Generally speaking- I'm supposing a bit.)

So it's worth spending that little extra for the better machine to start with, plus the warranty support.

Doc.
 
Thanks for all the replies....

Doc...Thanks for the detailed reply. Those were the exact questions and issues I was concerned with. I would have one additional problem. Even if I could run the machine before purchase, I wouldn't know what I was looking at. I am buying a machine and then learning how to use it. So, I think I will skip the Bridgeport for now. Enough room and 3 phase is not an issue. At least for now I have a lot of room in my shop (38X40).
 
Charles, I have a grizzly tabletop 1.5 h.p. and mill most of my frames with it, for what I'm doing (slippies) I dont think I'll ever need a bigger one and we are talking 1k for a new machine

The benchtop mill from Industrial Hobbies has 12"y 30"x and a 22"z.Seriously,go to their website and read the comparisons between it,grizzly,and rong fu.It is as ridged as a bridgport,has bridgport capacities,and is a benchtop.Plus many other upgrades.
