GrindoSonic The Impulse Excitation Technique





GrindoSonic    

When thinking about non destructive testing the only name I can think of is GrindoSonic.
They are located in Belgium and along with a great Beer like Chimay, Dan the Metalworking Man also is very fond of GrindoSonic.  When I am testing for cracks in brake pads there is no other machine I trust except for GrindoSonic.  They have been around for over 50 years and it is a name I trust for non destructive testing.  Nothing ever gets damaged when using their device and Dan is always happy when using it.  Then I grab a Chimay Beer and chill out.

Acra Milling Machine is best Bridgeport copy around? 
Bridgeport Series I Milling Machine

Acra Milling Machine vs. Bridgeport Series 1
Bridgeport Milling Machines certainly are one of the best made Milling Machines around.  Very similar to having a Harley Davidson Motorcycle.  It is built sold as a freaking rock.  A Bridgeport Mill is really beautiful to see in person.  The image brings you back to a time in America when things were made in U.S.A.  However, what if you don’t have a budget the size of NASA?  Is there an alternative for about 1/3 of the cost?  A Machine that can pretty much do all the things a original Bridgeport Machine can do?  While buying anything American certainly is a noble cause.  If you have the funds, we highly recommend it.  However, there are times when you need a milling machine and can’t justify spending well over $20,000.00.  We think that a great alternative in this case would be to look at the Acra Milling Machines.
  1. The quality really is incredible on the Acra Milling Machine and you will not sacrifice functionality either.
  2. For under $8,000.00 you could get yourself an incredible Acra Milling  Machine and start making parts in your machine shop within a weeks time from placing your order.
  3. The Acra Milling Machine comes standard with Digital Readout and Power Feed.
The Milling Machine has been called the “Mother of all Machine Tools.”  It certainly is a piece of machinery that is a must have in any machine shop or factory.  When the budget simply isn’t there and you want to get yourself a high quality milling machine what do you buy?  Penn Tool Co., recommends Acra Milling Machines.  With all the money you save buying an Acra Milling Machine you will be very happy.  Please contact one of our customer service representatives and Penn Tool Co., will find the perfect Acra Milling Machine to suit your needs.

Birmingham YCL1236GH Lathe



Well I waited a long time and finally bought my 12 x 36 lathe.  I picked the Birmingham YCL1236GH because all of the good feedback I heard on the web in places like Practical Machinist and cnczone.com.  Figured it was time for Dan the Metalworking Man to get one of these suckers and make some custom parts for my 1965 Ford Mustang.  It took some time to get it downstairs into my basement, but with the help of a few close friends it was possible.  It was crated when delivered and we left the wood on the bottom.  Slowly but surely we eased the lathe down the stairs until it was in the basement.  Once there we easily set the lathe up and it looks great in my Workshop/Mancave.  It won't be long now until I start making parts and getting my money out of this investment.




You can pick one of these up at Penn Tool Co for around $3,195.00 at the time I bought mine.  I looked around all over the web and from what I read the Birmingham makes a great lathe.  There were a few minor parts missing off the parts list.  Nothing too big and Penn Tool was quick to get the missing parts out to me.  Hey it happens.  No worries.  It is up and running and I am one happy Metalwoking Man.  Dan is putting his seal of approval on this one.  The Birmingham YCL-1236GH  Geared Head Gap Bed Precision Engine Bench Lathe is certified Metalworking Fresh by Dan!

#Digimatic Calipers

Dan the Metalworking Man found the greatest site for Digimatic Calipers!
http://www.digimaticcaliper.com/

They have all the Digimatic Calipers you could need at the best prices around.
Take it from me, Dan the Metalworking Man.


Digimatic Calipers

500-752A refinement now popular is the replacement of the analog dial with an electronic digital display on which the reading is displayed as a single value. Some digital calipers can be switched between centimeters or millimeters, and inches. All provide for zeroing the display at any point along the slide, allowing the same sort of differential measurements as with the dial caliper. Digital calipers may contain some sort of "reading hold" feature, allowing the reading of dimensions even in awkward locations where the display cannot be seen. Ordinary 6-in/150-mm digital calipers are made of stainless steel, have a rated accuracy of 0.001 in (0.02 mm) and resolution of 0.0005 in (0.01 mm). The same technology is used to make longer 8-in and 12-in calipers; the accuracy for bigger measurements declines to 0.001 in (0.03 mm) for 100–200 mm and 0.0015 in (0.04 mm) for 200–300 mm.
Many Chinese-made digital calipers are inexpensive and perform reasonably well. One point worth noting is battery current when they are turned off. Many calipers do not stop drawing power when the switch is in the off position; they shut down the display but continue drawing nearly as much current. The current may be as much as 20 microamperes, which is much higher than many established brands. Sometimes calipers may not work properly when the battery voltage has dropped relatively little; silver cells, preferably selected from a datasheet to have a constant voltage for most of their life, may give a much longer usable life than alkaline button cells (e.g., SR44 instead of LR44).
Increasingly, digital calipers offer a serial data output to allow them to be interfaced with a dedicated recorder or a personal computer. The digital interface significantly decreases the time to make and record a series of measurements, and it also improves the reliability of the records. A suitable device to convert the serial data output to common computer interfaces such as RS-232, Universal Serial Bus, or wireless can be built or purchased. With such a converter, measurements can be directly entered into a spreadsheet, a statistical process control program, or similar software.
The serial digital output varies among manufacturers. Common options are
Like dial calipers, the slide of a digital caliper can usually be locked using a lever or thumb-screw.
Some digital calipers contain a capacitive linear encoder. A pattern of bars is etched directly on the printed circuit board in the slider. Under the scale of the caliper another printed circuit board also contains an etched pattern of lines. The combination of these printed circuit boards forms two variable capacitors. The two capacitances are out of phase. As the slider moves the capacitance changes in a linear fashion and in a repeating pattern. The circuitry built into the slider counts the bars as the slider moves and does a linear interpolation based on the magnitudes of the capacitors to find the precise position of the slider. Other digital calipers contain an inductive linear encoder, which allows robust performance in the presence of contamination such as coolants. Magnetic linear encoders are used in yet other digital calipers.
