Notching VERY Short Pieces of Tube

admin

I posted some pics on the JMR website this morning showing how their JMR TN1000 tube and pipe notcher can notch short sections of tube.Check it out here is you want:http://www.jmrmfg.com/how-to/notchin...ieces-of-tube/"I Build Stuff"www.jmrmfg.comwww.509media.com
Reply:Looks like the edge of what the vice will hold - nice setup. Can the lower jaw move to the right any?To get even shorter maybe you can make a fixture from a shaft collar welded to a piece of tubing with an OD at least as big as the collar. Shaft collars are inexpensive and available in a wide range of sizes.Lincoln SA200, HH135, Lencospot, HF80 Inverter, Rockwell 11x35 lathe, HF drill mill, Kama 554 tractor w/ FEL & BH, Belarus 250AS, lot's of Chinese tools
Reply:I haven't seen this brand before- around here all I see is JD-squared.  I'm going to check out the pricing and availability (the price is the reason I don't currently have a JD2).Lincoln AC225 & MigPak 140, Lincoln Magnum SpoolGun, Miller Spectrum 375-X Plasma, Syncrowave 200 TIG, Millermatic 252 MIG, Miller Digital Elite, General 7x12" horiz/vert bandsaw, 3' box/pan brake, 20 ton press, milling machine, 12x28 lathe, etc.
Reply:OUCH!  I don't think I'll be picking up a JMR either!  I just checked the prices- and for those interested in the comparision- the JMR sells for USD$595 while my LWS sells the JDS-TN100 for $319.95 and the JDS-"Notch Master" for $439.95 (Canadian dollars). And the latter will notch up to 3" tubing while the JMR's max is 2 1/2".  Looks like a very nice tool though.  Maybe one day...  Lincoln AC225 & MigPak 140, Lincoln Magnum SpoolGun, Miller Spectrum 375-X Plasma, Syncrowave 200 TIG, Millermatic 252 MIG, Miller Digital Elite, General 7x12" horiz/vert bandsaw, 3' box/pan brake, 20 ton press, milling machine, 12x28 lathe, etc.
Reply:Not knowing your project, but couldn't you just use a longer piece and notch one end then notch again, cutting off the short piece you need and giving you more to clamp??? Know what I mean? Just interested200amp Air Liquide MIG, Hypertherm Plasma, Harris torches, Optrel helmet, Makita angle grinders, Pre-China Delta chop saw and belt sander, Miller leathers, shop made jigs etc, North- welders backpack.
Reply:The JMR has a wider rake with the ability to cut in a 210* or so arc.  It's the only hole saw notcher to my knowledge with that feature.  I don't think comparing it to either the JD2 TN100 or the Notchmaster (both of which I've used quite a bit) is apt.  Price wise it's more along the lines of the JD2 Beast but with a different layout.  JMR makes quality tools and I think given the materials and construction it's a good value.  Not cheap, but a good tool at a fair price for the tool.On Edit:  The Baileigh TN-250 looks good too, due out soon.Last edited by dstevens; 04-29-2010 at 03:43 PM.

Reply:Looks goodYa gotta spend money to make money!
Reply:JMR released a new notcher stand a couple weeks ago at IMIS.  This stand makes it very easy to fixture tube for repeated notches.  Check out the pics here....http://www.jmrmfg.com/featured-tools...notcher-mount/"I Build Stuff"www.jmrmfg.comwww.509media.com
Reply:I see all these hole saw based coping jigs/notchers and begin to wonder what the advantage is over a hydraulic coping machine for shop work.  We have two of them, not sure the brand on either of them (they have been ground on, painted on, greased over etc.) but I can cope from 3/4"-6" schd 120 on either of them just by swapping dies.????  About half a second per snap.
Reply:Cost!  You thought the hole saw based ones were expensive.  I can't imagine what the hydraulic one costs.  You can buy a new hole saw, maybe $10, and work a new pipe size.  How much does a set of dies for the hydraulic machine cost?Dynasty200DX w/coolmate1MM210MM VintageESAB miniarc161ltsLincoln AC225Victor O/A, Smith AW1ACutmaster 81IR 2475N7.5FPRage3Jancy USA1019" SBAEAD-200LE

Reply:As far as cost goes, I bought ours used when another shop was folding - I agree, can't bore a hole with it - Extreme angles are a matter of the right die and operator skill.BTW, that is a sweet looking setup - would like to see an overall shot of it once its done.  Someday i would like to get set up to bend tubing like that.Last edited by SRO1911; 12-17-2010 at 09:10 PM.

Reply:That is an incredible piece of work.  I have picked up a TIG maybe a dozen times, then decided it took some kind of voodoo that wasn't flowing round theses parts. I someday want to beef up my THING like that - or better yet find some way to smuggle it across the border to you.
