Re: Getting Older.

I have what's now looking to be permanent issues with my sciatica from being young and real stupid about lifting more than I should far too many times. The exercise is a good thing and not arguable, but the human body is capable of only so much. And much less so as you age. In both Canaduh and the U...

Re: Setting lathe compound to 90 degrees

It depends on how often you move that compound, but always having to indicate it back in to being parallel to the ways would get old pretty fast. If it were me I think I'd try and figure out a simple machined plate that auto indexes the compound back into being parallel using datum surfaces that are...

Re: Diagnosing a Milling Machine problem

I did a bit of thinking about this thread. Is this a new to you collet and/or endmill? In other words has this collet worked in the past on another endmill or tool shank without issues? That apparent internal lobbing while the tool shank is spun in the collet is for sure a definite indication someth...

Re: key type chuck with R8 mount

Getting a good, well made and low runout keyed chuck today is a tough one even without the integral shank requirement. I have seen a few in the past in tool catalogs but not lately. Some but maybe not all keyed chucks can be drilled and tapped for a jacking bolt to help separate an arbor from the ch...

Re: Jet 1336 PBD Lathe

Sometimes running a Google image search using the model no. can turn up lathes of the exact same type only painted and have a different model number for various country's or tool suppliers around the world. Visiting that image page can sometimes get other model numbers to run search terms with. Even...

Re: Got a Align Power Feeder

It's probably still on there website but last time I checked Servo has about the best install directions out of any other source I've seen. There directions work with these clones. For mine you have to vary the number of shims used to set the tooth engagement on the crown gear. Shim it too loose and...

Re: Got a Align Power Feeder

Something you might already have figured out but if not it might help. An easy way to get your feed screw measurements for it's C/L is run the table in as far as you can on the right hand end your installing the feed unit on. Then pull the hand wheel and end bracket. The feed nut on the X axis will ...

Re: Got a Align Power Feeder

Yeah it's probably going to be a bit of a juggling act getting that new end bracket machined so you have your alignments correct in 3 dimensions. And lot's of measuring and trial fitting. I'm not real impressed with those inline power feeds either. I tried one years ago at the Grizzly showroom. The ...

Re: Got a Align Power Feeder

Align are supposed to be one of the better copies of the Servo power feeds. Mine's a no name version bought from Grizzly some years ago. It's ok and the bracket and everything else bolted right up to my BP clone. I get a bit more gear noise than I'd like, but apparently that's common. Finding the co...

Re: HEIGHT Gauge question

Standard industry specifications for accuracy of metrology equipment is + - one count. Actual measuring and marking out are totally different. And you said measuring. Adding a 10ths indicator zeroed to a surface plate will still only allow height measurements to the accuracy level of the tool and it...

Re: Good practice question

Textbook recommendations in the books I have all say a maximum of 3 times the diameter for part length outside the jaws. In practice I've found that to be generally correct. But there's a dividing point where common sense kicks in. For a real large shaft on a big lathe I wouldn't expect any chuck to...

Re: feeling stupid

Successfully single pointing a hole of that size in a part shape like that automatically removes the stupid part. Your now well up to possibly and only sometimes a bit mistake prone with taps :-) Very well done.
