Drilling Through Tube With the JMR TN1000

Thursday, May 6th, 2010

The JMR TN1000 Tube and Pipe Notcher is the most versatile hole saw notcher available.  We have been posting different tasks that can be accomplished with the JMR notcher.  Unlike notchers that are large, bulky, and clamp all the way around the tube the JMR notcher can be used on a vehicle or project.  What I mean is after tube is welded in place on your vehicle the JMR notcher can be clamped directly on the project to drill holes and even notch tube.  The following pictures show how you can use a 3/4″ hole saw to drill through tube to insert a weld in shock bung.  This can be VERY useful drilling in position to ensure shock mount locations are exact.

The JMR notcher can drill through square tube on the flats or on the diamond.  On the diamond refers to through the points.  Again a big advantage is the holes can be drilled in place after your project is welded together.

Notching Short Pieces Of Tube

Thursday, April 29th, 2010

The JMR TN1000 hole saw notcher has a movable vise which allows it to notch very short pieces of tube.  In the pictures you will see how the vise slides up close to the hole saw.  The JMR TN1000 is the ONLY hole saw notcher on the market with a movable vise.  JMR incorporated this design feature because the person designing the tool actually has practical fabrication experience and very little experience staring at an office wall.  Notching short sections of tube is only one feature the JMR TN1000 offers.

See more pictures of the JMR TN1000 HERE.

You can find the notcher in our ONLINE STORE HERE.

Another great feature the JMR TN1000 offers is the ability to notch flat bar.  You can read more about this feature and see pictures of the TN1000 in action by looking HERE.





OK, now you have seen the most logical way to notch a short piece of tube.  Now I will show you a way to notch tube even shorter.  The method pictured below is from years of experience in the shop fabricating race trucks not sitting on the internet reading about how others fabricate.  If you EVER have questions about how to use a JMR tool feel free to call or email.

If you would like to make the tool used in the JMR TN1000 below it is very simple to do.  Cut a 5 inch piece of tube that will slide over the tube you want to notch.  With a cut off wheel cut a slot down the length of the tube. Make sure to leave about 1/2 at the end of the slot.  In other words DO NOT cut all the way down.  The slot is cut in the tube to allow it to clamp down around the work piece. Make sure the 1/2 inch you left is at the opposite end from the piece you are notching.  Insert the short piece of tube you want to notch and clamp down in position.  The JMR vise will allow you to clamp down firmly to hold the short piece of notched tube.  If you have a different brand of notcher you can can still do this procedure.  Depending on the brand notcher you have you may have to use a radiator hose clamp out toward the end of the tube to help hold the tube.

Making Tabs with a JMR TN 1000

Tuesday, March 9th, 2010


The JMR TN1000 was designed to notch tube and pipe.  You can also cut flat bar to make brackets and tabs.  Below are some pictures we took this weekend at a trade show demonstrating this process to on lookers.  The flat bar in the demo is 1/8 inch thick.  You would not have a problem cutting thicker flat bar.  If you have any questions be sure to post up below or feel free to contact us.
