Penetrating Oils I received this in an e-mail today. I did Google "Machinist's Workshop MagT" and found the same information on several Machinist Forums. I don't know how reliable it is. I have also heard that anti-freeze works well. Penetrating Oils Penetrating Oils Machinist's Workshop MagT recently published some information on various penetrating oils that I found very interesting. Some of you might appreciate this. The magazine reports they tested penetrates for break out torque on rusted nuts. They are below, as forwarded by an ex-student and professional machinist. They arranged a subjective test of all the popular penet…

Picked up this shaper yesterday. It came out of a garage in Austin - a nice young man bought the house and this came with it. I was fortunate that he was patient enough to work with my schedule since we've been discussing it for several weeks. Everything seems to be in good shape but it is missing the vise so I'll be on the prowl for one of those. I also picked up a very nice Peter Wright 133 lb anvil - didn't need it but kind of fell in my lap. No pics of that yet but it's also in good condition - besides the usual weight and brand lettering, it also has a large "E" stamped on the end of one foot that appears to have been done at the factory. Anyone know what that…

Found this on craigslist the price was right and it was close enough for me to go pick up. It is in great condition very little use, the guy used this shaper and a small mill to build scale trains. Now I just need some hold down clamps and I will be up and running. I removed the motor and stand for loading

It has stood unused for several years and after an exchange of comments with Macbruce about his Zipmax machine, I was motivated to get this Pullmax of mine into commissioned work. It just needs rewiring and then it will be complete and functional. I had to make a few bits and pieces that were missing but I had it running before I started to strip it down. It was actually quite a fun project.

Stumbled across this guys page when I was looking up Hackney Hammers, very awesome setup. http://sandersoniron.com/old/JoelWeb%20Page%203-studio-machines.htm

USING A FOOT SWITCH WITH A KB DRIVE Get a momentary on/off foot switch. Harbor Freight has one. http://www.harborfreight.com/momentary-power-foot-switch-96619.html You plug this into the wall and your VFD into this switch. If you step on the switch the motor will run, step off and the motor stops. If you plug the VFD straight into the wall the motor will run. Your start/stop switch has been disconnected. To set up a foot switch on the KB drives go to page 14 of your manual section 5.5. If you are installing a fwd/rev switch you have to remove a jumper that is in the upper left corner of the VFD and plug wires from the new fwd/rev switch into those contacts. …

I have my tumbelina built and hooked up a 1 h.p. d.c treadmill motor. Not enough oomph, even with a .106 drive pulley ratio. So I need some schooling on gear reducers. How are they rated? For example, here's a badge off a 15:1. Do I have to be within a horsepower value to match a particular reducer? How much torque would one expect to gain? Any other tips for the uninformed?

Anyone on the site use or have CNC experience. Please contact me PM or post here. Thanks

So to set up a belt line I want to use a little 4 banger motor to drive the belt. I was wondering if this one would be best suited to my shop. I would only be running a drill, grinder, possibly blower, and maybe a home made power hammer. Have a good sunday

I am looking at an air compressor on Craigslist. no information given other than the two pictures posted. I have a small craftsman air compressor for general use, but was hoping to find something with a little higher cfm at high pressures for use with tools like a sand blaster. I know this is alot to ask, but anyone have any kind of clue on the stats on a compressor like this one in the pictures?

I have several old power tools that seem to work fine, however when in use I can see bright electrical sparks in the motor. Is this normal or safe? thanks.

Its a Sears and Roebuck 103.2428 I think. It looks exactly like a King Seely with a aluminum tan painted housing. Needs tires, other than that she runs like a sewing machine

Can anybody please tell me what the symbol circled below is?

Hi All, Just picked this tumbler up at a plant closing (they made the hooks and stuff you find in hardware stores). Looks like it was built in the plant-it is a nice design-easy to build. If anyone wants dimensions and such let me know. Real time saver. Overall length is about 6 feet-it'll take a 4 foot piece of material. Best part is I got it for $100.

OK, I'm thinking of putting a bid in on this thing so I need some input from you all as to it's worthyness. http://www.ebay.com/...=item4ab434654e I can't go much more than $50 or so but if you think it is worth more than that also let me know and I'll see if I can talk the wife into letting me go a little higher and if you want I guess the sky is the limit :blink:

I have three phase power in my shop, but the voltage is 208 not 240, and I'm confused about what the implications of this are. After doing some research online, I've read conflicting information as to what a 208/240 rating on a motor means. Some people said that it means the motor will run okay on either input, but others stated that the 208 rating simply indicated the low end of acceptable input voltage, and that a true 208V input will often run below this, causing the motor to draw more amperage than it is rated for. Does anyone know which of these is correct? Also, if the latter is true, is it acceptable to use a 240V motor with more capacity than is needed to accommod…

If I wanted to build a large rolling mill, which roll would bend less, given a 16" length and a force applied to the center: 6.5" diameter 4140 heat treated or, 8.5" diameter 1045. Both would be surface hardened. This is for cold rolling of bronze. Tool steel is too expensive. Thanks!

Okay, well I'm sure some of you lucky smiths on here have all the power tools & tools that anyone would ever want or need. I'm wondering what you should have, and what WOULD be nice to have. From what I've been doing so far, I really need a drill press & bandsaw. I'm getting a drillpress in about a week. BTW, for those of you who were wondering, my shop is done, everything is really sweet (for me at least. lol). I'll get pictures as soon as I can, camera isn't working. John & his friend quentin.

Going to put this back in service. Just had to roust up a low rpm 2hp motor and a drum switch. Been repaired but I think it will roll on.

Please tell me about your VFD set up on your belt grinder. 1. Brand you have. 2. Input voltage & phase. 3. Output voltage and phase. 4. HP of motor. 5. Nema 4 or in another enclosure? 6. Best feature? Thanks, Jamie Herring

I have a contract that calls for radiuses (sp) in 1/2 " solid steel square bar. Many Pieces, I think a roller type machine with 2 fixed, powered, reversible rollers,and one adjustable rising vertically through a table, might be what I need. Anyone know of particular brand names and , of course advise from IFI 's bottomless well of knowledge, will be appreciated. 3 phase 240 volts is my shop power. thanks.

Hi all, I am trying to figure out how to hook up a rotary phase converter to a 240v 7 1/2hp 3 ph motor on powerhammer. I would like it to be running before being able to turn on the machine. I have have only the one machine so I usually turn on converter and then the machine but sometimes forget the converter is not running and hit the machine on and it is not happy. I was thinking of using the generated leg of the rotary to power the pushbuttons for the machine so if the rotary is not running then nothing would happen by pushing the start. Stupid idea? Is there a better way? Thank you Rob

I want to start by saying I'm not a machinist, but want to start as a hobbyist. There is a old shaper on a local classified site, and i was wondering would it be worth the trouble to get this or is this considered obsolete. Maybe put time and money into a milling and lathe machine? This is the link. Ksl.com Thanks for any input. Chad J

Firstly I come from(and now live in) a part of the world that uses 240V domestically and 380V industrially, by and large. I have no knowledge about 110V, this may or may not aply to 110V motors. A lot of guys see electrical motors in Scrap/junk yards but are weary of buying them in case they don't work! Well you can "test" them and be 95% sure with a multi-tester that can be bought cheaply . As shown set your tester to check continuity as indicated in the first picture. now test that each of the 3 points as indicated with the blue ferrules(in a line) with each of the others - they must each make a circut. Now check that they do not make a circut with the earth as …

I realize this is not a machine tool, but I bought it from a machinist, does that count? I picked this up at a yard sale for $10. It weighs about 50#. NIKON 6969 is all that IDs it. I have searched the web with no success.This thing finely adjusts in X,Y,& Z axis. Maybe it's for an X-Ray machine? I had to have it, it was to cool to pass up. Thank you for your help!
