OL' Joint Jigger Tube and Pipe Notcher Model RTN 1000
Jun. 01, 2002
Got a new project going, maybe you are
building a roll cage, or adding some tube supports to a previous
cage. Any place where tube meets tube you need a properly
shaped notch to get good solid attachment. Take a look at
what Ol' Joint Jigger has to offer and make those notching problems
a thing of the past.
Heck, if you need an
excuse to help get your new tool, you can use it to notch tube so
you can make your kids a nice set of monkey bars, or maybe your
friends want to make a new hunting stand, the possibilities are
endless. If it's 2" or smaller, this tool makes quick, easy,
Here are a few quick shots
to show you what you get with the RTN1000.
Right out of the box you notice the quality of the piece, the main body and mounting foot are made of nicely anodized aircraft grade aluminum. All hardware is grade eight. The T-handle and arbor are made from hardened polished steel. The tube clamp is V notched to automatically center your tube. The angle marks on the built in protractor are laser engraved from 0 to 60 degrees in one degree increments for easy trouble free setting, no stickers or painted on marks to fade or fall off here.
On the unit we obtained, we had a couple of optional parts included because we were planning on notching mostly 1.5" to 2" tubing. They offer a Torrington Needle Bearing Arbor support, and a Large Thread Arbor, just for the large size hole saws. (usually from 1.25" up to 2")
The included Arbor is threaded for 1/2" x 20 threads and has a screw on adapter for 5/8" x 18 threads that the larger hole saws use. The Torrington Needle Bearing Arbor support does offer a longer life than the stock bronze bushings, but it makes the joint cuts about 1/1000 of an inch less accurate. (hmm, I don't know about you, but I can't see quite that good, nice to know the tool can make cuts that accurate though).
The mounting foot on the RTN1000 allows you to bolt it down to just about anything flat, or clamp it in a vise (with some padding to keep from destroying that fine anodizing of course). It also allows you to pivot the tool for much greater flexibility when needed, so that you can notch that oddly bent or awkward piece of tube. These shots show the RTN1000 installed on a stand that I quickly fabbed up.
Here are a few shots of pieces of tube that I notched with the RTN1000, as well as what some joints look like with and without notching. As you can tell, the notched joint makes for much better contact and stronger easier welds to be made. We used Lennox brand hole saws for the cuts we made and they have not slowed down a bit after quite a few notches cut. Take your time and feed the saw into the metal nice and easy. On thicker tube, use a little cutting oil to keep the saw teeth cool. This will make them last much longer. Also always wear safety glasses, the tool can send metal shavings flying all over as its cutting.
We were very pleased with the performance of the RTN1000, if you need to do a good bit of tube joints we would highly recommend the RTN1000 from Joint Jigger as a great tool for the job, give them a shot, you wont be disappointed.
