    Anyone know anything about milling machines and prices? I want one for tinker building... I know some can cost quite a bit. I'm searching for brands and hobbyist prices, but still worth it's salt when it comes down to machining....

    What got me interested was a webpage about hobbyists that build there own small jet engines, 10-100 pounds thrust... Besides that I just like fabricating.

    Those prices are fairly reasonable... Still I'm think maybe I could find one used locally. I like the idea of CNC to... When I get my hands on an expensive block of aluminum I'd be sure to mess it up.

    One of my customers has a machinery sales and service business. I just got a 1981 Bridgeport miller with a new 2 acess readout that does bolt circles. It came from the company that I worked at for 20 years. I ran this machine when it was new. They traded in 2 old millers for a new Trump with a 3 acess system. He always has used equipment for sale and will ship most any where.

    Ahh..milling machines..you'll find these tools to be a "must have"after test driving.I purchased a Bridgeport with double axis DRO(older model)..for a couple k from a dealer 10 years ago and shes still with me.Depending on what your using the machine for,small hobby work or medium size jobs,there is one built for your preferance.There are the drill/mill bench types Jet sells for under a grand,which last a while but tend to loosen up and rattle after extensive use....and there are the knee type mills,quite a few selections and prices when choosing these.My suggestion is to go to used machinery sites and browse around..But before purchasing a used mill be sure to test drive..you never know.Listen to the sound of the mill as you start it up.This tells you a lot.Arbor bearings recieve lots of abuse.Check the table slides,if"play"exsist wedges may be adjusted.A machine is like a good woman...press the right button and she'll show you what she can do...abuse it and she'll cost you a lot"...Good luck

    Im a Apprenticed Tool and Die Maker with 15 Yrs Experience. Take Knee Deep is exactly Correct. Smithy is Garbage ive known a few people that Bought these machines and were disatisfied. An older Bridgeport Or Brown & Sharpe would be your best bet.

    Hi,
    I am a tool and die maker / machinest for 22 years now. Go with either a Bridgeport or Index brand. The things you want to check on a used machine are: Play in the spindle bearings, play in the table gibbs and the low speed shifting lever mechanics. Lots of the manual shift machines get abused due to the lever being hard to mesh the gears in. I hear guys grinding them all day long not getting them in gear right before flippin the switch. How to check spindle play quickly is: put a dial indicator on the table with some type of fastener. Where you buy the machine should have stuff to check this out. extend the quill down. Put the indicator needle on the quill torward the bottom. set it so it can move both directions a bit. Pull some on the quill and if the indicator moves more that .005-.010 the bearings are probably shot. Leave the setup right there and lock the table down in all direction with the locking levers. Now pull and push on the table. this will show you how bad the gibbs are. Keep in mind all this stuff is replaceable and inexpesive if you do it yourself. I hope this helps some. There is alot of junk out there that a close tolerance shop cant use, but will work fine for the home hobbiest
    Hope ive helped some, Larry

    I just got done making a milling attachment for my 9" Logan Lathe. I am very limited in what I can do, but for the beginner (which I am), it has been very nice. My lathe was given to me. It came out of a school shop that had been junked (meaning: they took their property control tags off). It has been a great machine for me to learn on. I would love to have a bridgeport. Maybe someday.
