found this unit jet mill /drill from 1988 guy wants 800 i don't think its worth anywhere near that much what do you guys think i know its not great but for a Lil milling it might work for me  http://yuma.craigslist.org/tls/2293039302.html350P 30A spool gun cut master 51  syncro 250 other stuff " take a dog off the street and make him prosper and he will not bite you sad the same cannot be said for man" i didnt use punctuation just to piss you off
Reply:I'ld say it's worth it, especially if it wasn't used in a production environment. It looks to be about the size of a Bridgeport, which usually starts out at $1500 for a worn one. Still, it is Chinese, so you'ld want to check it out thoroughly for casting defects.
Reply:No.  Not even close to the size of a bridgeport.  It's a mill drill.  It's the older version of the Grizzly G1005Z (it's a chinese import machine).  The current version is only $895 from Grizzly (http://www.grizzly.com/products/Mill...hine-25/G1005Z).  Rusted up like that, I wouldn't give more than $300 for that and even that would be stretching it.--Wintermute"No man's knowledge here can go beyond his experience." - John Lockewww.improvised-engineering.comManufacturer Agnostic:Blood----------Sweat---------Tears----|------------------|----------------|----Lincoln Red, Miller Blue, Esab Yellow
Reply:Yeah, $300 or so is what they go for.HF has the same one for $1200, but with the 20% coupon, that's $960, NEW.http://www.harborfreight.com/1-1-2-h...ine-33686.htmlI've got one, and it's nice enough, but cannot be compared to a Bridgeport in any way.
Reply:Hey uma,That mill is a superb unit & one of the "older" ones made in Taiwan. It is quite heavy & the unit is very well made & quite accurate. I had one where I worked & when we closed last year, I sold it for $1000 as that unit is $2300 new. It is not a cheap "chinese" unit as some would project. Jet makes very good equipment. With a collet set, vise, & stand, $800 is a fair price, although $600-650 would be a steal. With a bit of oiled crocus cloth & alum. block, the table will clean up like new. Here's a pic of the one I used at work.....looks to be the same.Denny Attached ImagesComplete Welding/Machine/Fab.

Reply:Sorry, you guys are completely wrong about the size. The one on Craigslist has a 9-1/2"x31-3/4" table, and is a 2hp machine. That doesn't compare with the ones you all are describing.

Reply:I would offer him 600.00 & go from there, to be honest,  i would go to 750.00 without hesitation after seeing it run. I just gave 900.00 for a 1987 enco knee mill with 4 vises & think i did real good on it, it runs like a champ.                                 Bob
Reply:Originally Posted by MoparfeverJust for reference, the smaller series 1 Bridgeport had a 9" x 32" table, and was only 1hp. Of course the Jet isn't a knee mill.
Reply:I vote "Not worth 300 - 400...if even that..... around here anyway.............
Reply:I had a mill drill for many years. 2 hp I think. Bought it w/ a stand and a tool assortment for about $1,000.  Tools included R8 collets, drill chuck, vise, step clamps.  Made a lot of parts with it.Sold it a couple of years ago (less tools) for $900 and got a brand new Tiawanese 10 x 54 knee mill w/ variable speed pully, one-shot lube, power x feed....$4,500.  Added a nice Newall DRO.  Absolutely love it!  WAAAAAY better than the mill drill.Of course, there's really no comparison between the mill drill and the knee mill.  They kinda look like they do the same thing but they are worlds apart. Like Wintermute said...it's not a Bridgeport (read knee mill?)...even if the table size is close.Mill drill pros: inexpensive, lightweight (if/when you have to move them), use the same tooling that a knee mill (may) use, easy to take apart to clean/maintain, most use 110volt.Mill drill cons:  Speed selection is limited, speed changes are a PITA (and you need to be able to change speeds alot), no knee means you have to reestablish your reference if you raise the head (MAJOR PITA), light weight means more vibration/chatter, brass saddle nut wears out if you set it too tight (to take out the lead screw play) or get the gibs too tight (to take out the table play) handles get loose and fall off alot (but now that I think about it, handles on non-Japanese Asian machine tools seem to always fall off.), won't handle large parts, no auto-feed on the quill (nice feature), no back gear for really slow speed.So there....way more expensive tools are nicer....duh!  You probably figured that out for yourself.  But if you just need to occasionally cut up some aluminum or plastic and end up using it mainly for a drill press it would be fine.  I wouldn't give more than $300 for this one though...looks kinda rough.  If I was selling something like this I would at least take the time to clean it up!  As yorkipap pointed out, steel wool or scotchbrite pads and some paint thinner will shine up the table and column and make it "look" like new.Miller 211 w/ spool gunMiller Dynasty 200DXLongevity 60i IGBT plasmaO/A w/ crappy chinese torch/gaugesSouth Bend 10K latheGrizzly 4029 10x54 millGrizzly 7x12 hor bandsawangle grnders, bench grnder, bench belt sndr7.5 hp 80gal cmprsor

Reply:Mine came on a pallet with the mill drill, base, collet set, and hold down block set all banded and wrapped together and weighed in at (old memory files here) 780 or there abouts. Been awhile but the 760 lbs to 790 lbs is where it was with all the above. So separate out the base and little goodies the mill drill itself had to be in the 650 lbs to 680 lb range. (same model just newer)It was a booger for a one man show and no special tooling other than roof joists and coffing hoists to set it up on the stand. Made the joists creak and crack."The things that will destroy America are prosperity at any price, peace at any price, safety first instead of duty first, the love of soft living and the get rich quick theory of life." -Theodore Roosevelt
Reply:You all are right about the Bridgeport comparison. I was talking the ability to handle "x" size workpiece, not mass and rigidity. When it comes to the ability to bite through steel there isn't much comparison. Still, I've never seen a mill that size go for any less than about $600 around here. For $300 you'ld get a used HF.
Reply:Hey guys,There are quite a few members on the forum that could use a good mill, even a smaller unit such as this Jet. Most of us in the welding/fab/machining arena really don't get heavy steel/other materials that need turned or milled, & if we did, I'm sure there are outlets that could service our needs for a larger repair. Now, if we did get a lot of heavy work in, then a minimum size, like a Bridgeport or larger would be a necessity. Those who have never used a Jet like this one, or even LOOKED at one, have no idea(like member 1awert1) of the value of a good used mill......no matter where you are. The Craigslist pic, although not really clear, shows what appears to be rust, although sitting idle could be simply a lot of dust, overspray, or plain 'ol dirt. The nameplate looks pristine, so that would indicate the machine has had little use. It's so simple to just go take a look at it, plug it in & turn it on, & look/listen to the unit running will reveal if it has been take care of. Looking at the belts/pulleys will also reveal if the unit has been run hard & has had the crap run out of it. The C/L poster indicated it was used "TWICE"...... maybe/maybe not, an inspection will substantiate those claims. That unit would be an ideal mill to get your "feet wet" in the machining arena & enhanced by a vo-tech/college class to learn the basic fundamentals. Most don't realize the value of a lathe & mill in a welding/fab shop.....quite lucrative & some really nice $$$$ can be made. Wouldn't take long for that unit to pay itself off easily. I used our Jet mill for 11 yrs daily & it ran like a Swiss watch with not one issue. Our work at the company was light milling & I did some personal heavier milling with it & with proper cutting parameters, not a hiccup. Don't underestimate the smaller mills.DennyComplete Welding/Machine/Fab.

Reply:Learning how to properly inspect a used mill or lathe is advisable for a newbie with no former knowledge.  Get a dial indicator and a magnetic base and learn how to use it!In addition, it would be well worth your time to research the value of all the tooling which may or may not be included in the deal.The best way to spot a good deal is by educating yourself beforehand.

Reply:Hey uma,Glad to hear you got it.....& I believe you got a great deal. Post some pics of it. You will find that it is a rugged unit that will give you good service.Did you get an operators' manual with it? There are adjustments & alignment checks you will need to do to insure the X & Y travel is precise. A good dial indicator with mag base will get  you started. There are table adjustments called gibs that will snug the table dovetail movements you will need to check. Here is the Jet site you can download the operator manual in PDF that will show you everything about that unit. Also, if you didn't get a chuck, get a good 1/2" one that will make it easy to change cutters & I believe that is an MT2. You can also find many types & sizes of cutters on E-Bay in the Industrial/Machining section very inexpensive.Dennyhttp://www.jettools.com/eu/fertigung...g_milling.htmlComplete Welding/Machine/Fab.

Reply:Just the difference between a drill press and a mill drill in simple drilling operations is significant. I still run to the drill press for most down and dirty holes because it's quick and easy, but when it really matters it's an automatic to go to the mill drill. You start drilling a bunch of 3/4" and above whether it's cheap hole saws, conventional bits or annulars, you'll have this little grin going on in the back of your mind thinking how glad you are that you got a decent device."The things that will destroy America are prosperity at any price, peace at any price, safety first instead of duty first, the love of soft living and the get rich quick theory of life." -Theodore RooseveltOriginally Posted by yorkiepapAlso, if you didn't get a chuck, get a good 1/2" one that will make it easy to change cutters & I believe that is an MT2.
Reply:Hey rlitman,You are correct on the R8 & not the MT2..... my bad. I've used a chuck for light milling without issue, although for any serious cutting, it would not be advisable, so it CAN be done & without injury.

Reply:I think you got a great deal.  Hard to find the older ones around here anyway.  That machine can do you just fine for a long time.  Do you have an MSC, Grainger or maybe just go to a good size machine shop and ask then if they have some tooling they would steel to help you get going.  Most guys will just hand you a few things to give ya a start.  Great find...
Reply:now thats a great deal, good for you!  I have had good luck with end mils from Graingers, a little pricey, but good quality & really fast shipping. I got a decent fly cutter that uses  carbide bits ( lathe bits) which work very well,off ebay for 35.00 & am gonna try an indexible end mill from  ebay also.  I am still learning, but playin around with the mill is great. good luck with it!

Reply:I like that stand that it's on. Lift it up on rollers to move it or set it down solid. I don't see any rust on there that'll be any kind of problem at all. It will all clean right up.

Of course a ratchet and extension will work fine for that too.Last edited by Sandy; 04-02-2011 at 10:32 PM."The things that will destroy America are prosperity at any price, peace at any price, safety first instead of duty first, the love of soft living and the get rich quick theory of life." -Theodore Roosevelt

Reply:As a new owner myself, I've been picking up tooling here and there trying to acquire the basics.  I bought the 20 pc double ended endmill set from Enco a few weeks ago.  They seem to be okay so far.  I figured for $2 per cutting end I could start with a good selection and replace the ones I use frequently with better quality as I need them.  Only ruined one so far.  My fault...switched to high range and forgot the cutter would run in the wrong direction. Oops.I also am using a vice like what you have pictured and have lost two parts due to them popping out while milling.  I would strongly suggest looking for a better one.  I haven't figured out which one to get yet myself.  I almost bought a Kurt the other day during Enco's 20% off sale, but couldn't spare the funds.  Hopefully I can get finished up and paid for a few jobs this week and be ready for the next sale.My name's not Jim....
Reply:You've a Model 34 with a JT33 mount. Would be the only size I haven't got. I'll get you fixed up with a CARE package of end mills in a day or so. Might even toss in a couple Asain ones to tear up quickly so you note the difference when you see it.As the previous poster noted, your vise is minimal...probably work a whole lot better on a drill press. Upside of it is that it is low profile. One never has enough headroom. I can't comment on the quality of the Kurt copies, but if you want to swing the purchase of a Kurt vise to fit you'll never look back.Here ya' go on a link for the right arbor for that chuck.http://www.use-enco.com/CGI/INSRIT?P...PARTPG=INLMK32eBay Buy-It-Now link.http://cgi.ebay.com/R8-JT33-DRILL-CH...item51987f35c6Last edited by WyoRoy; 04-03-2011 at 10:39 AM.Lincoln PrecisionTig 275Miller 251Miller DialArc 250Bridgeport millHossfeld bender & diesLogan shaperJet 14 X 40 latheSouth Bend 9" 'C'Hypertherm 900Ellis 3000 band saw21"Royersford ExcelsiorTwo shops, still too many tools.
Reply:Uma, go to www.cdco.com for a list of import tooling.  Fast service (order on Sat, have by following Thurs) prices are fair.  Most of the tooling is import, but for small stuff like your mill & my lathe, it should work ok.Give a shout if you need an extra hand or two, I'll swing by & swap a lie or two with ya.MarkI haven't always been a nurse........Craftsman 12"x36" LatheEnco G-30B MillHobart Handler 175Lincoln WeldandPower 225 AC/DC G-7 CV/CCAdd a Foot Pedal to a Harbor Freight Chicago Electric 165A DC TIG PapaLion's Gate Build
Reply:Looks like you got a great deal, especially with all the accessories. I would definitely stay away from milling with a chuck like others said. No reason to with the collets. A chuck is like a 3-jaw chuck in a lathe, and has more runout than a collet. That will cause inaccurate cuts, and can also cause the mill to grab, ruining your piece or breaking your cutter. Also definitely start thinking about getting a real milling vice, preferably a Kurt or Kurt copy. That drilling vice is your weak link, and you'll never know how rigid your mill is until you get rid of it. Rigidity is what your looking for, without it you'll get ruined parts, inaccuracy, and broken bits. Everything plays into it, from how you adjust the gibs, how far you extend the cutter, diameter of the cutter, and how you hold the workpiece. A mill will open up a whole world of new possibilities for you. Have fun!

Reply:Looks like a good buy. Like someone mentioned above, you should keep an eye out for a real milling vise, one with a rotating base will add a lot of versatility. When I had my round column mill/drill the biggest drawback to me was the lack of vertical travel in the head. You could raise and lower the entire head but then you lost the position relative to the work. (not like raising and lowering the table on a Bridgeport style). I saw a tip online to remedy the situation - rigidly mount a laser pointer to the head. Then on the wall opposite draw a vertical line where the pointer points. You can then raise the head and bring the pointer back to the line and not lose the registration to the work piece. You have to make sure your machine is exactly level and rigidly mounted to the floor for this to work.Happy machining!JimCut an MGB and widened 11" C4 Corvette suspension and LT1 Chevrolet power & 6 spd.

Reply:"Accurate to .002" on parallelism and Squareness"I'm not too sure about that vise.  It's got to be better than what you have now, but for another hundred bux or so you could have one a lot better.  If you're going to go cheap, there is one for about $89 on ebay.  I've been thinking hard about going with the cheap one and squaring it up myself.  Either that or just going with a Kurt from Enco for $407.  Less if a sale comes up.  The better vises seem to be parallel and square to .0002" or .0004".My name's not Jim....
