I think you'll like it if you do. I have them in 3/16", 1/4" and 3/8". I've done 0.028" wall stainless with the 3/16" and 0.035" with the 3/8" and the bends look great.

Thanks.

I ended up ordering the 400 series as it was considerably cheaper than the 600. If it sucks Ill return it and spend the longer money for the 600.

Its due today, so I should know before the day is over.

Got to play a little with the new bender. While it does a much better job (no kinks) than my cheap 3 in 1 bender, it still leaves the outside of the bend "flat". Im not sure if its the tubing or the bender, or perhaps Im just expecting too much and this is normal.

I'm also using a Rigid 400 series bender for 3/8 and have also noticed a little flatting on the outside of the bend with thin-wall steel tubing, but not so much with thicker wall tube. I can't tell if your Nicopp is flattening more, less or the same. Here are a couple examples of my bends:
- Thinwall steel for fuel lines, definitely some flattening
- Thickwall steel for hydraulic lines. Very little if any flattening.

If I can remember, tonight I'll pull out calipers and take some cross measurements to see how much flattening there is.

I wonder if the flattening you're seeing is because the NiCopp tube is fairly soft.

What size is that, 3/8"? I can see what I have at home that might be comparable and bend an example with my 600 series bender to see what it does. I've only done stainless and 4130, and haven't noticed it distorting the tube much.

Yes, its 3/8". I havent had time (or perhaps material) to try 3/8" steel. Ill check my stock tonight, see whats up.

If it's of any value, I measured .375 OD for both tubes linked above. The hydraulic lines flattened to .360 in the bend while the fuel lines flattened to .345. I'm sure it's material and wall thickness dependent. Caliper measurements.

Finally got out to the garage last night for the first time in nearly a month.

The tubing I did the test bend on flattened to 0.330", pretty horrible.

Im not sure what Im going to do. Im tempted to fill the tube with sand first (which we do at work for winding 3/8" copper tubing inductors).

What would be nice is a bender with double the radius as I dont need any sharp bends.

From page 24 of the SwageLock bender manual. it says the following...





Does that help any? I am learning along with you guys but I thought Swagelock might have a better grasp. Maybe the rollers matter? The Rigid doesn't use rollers does it?

It does help. Im returning the 400 series to Zoro and ordering the 600 series with rollers. Its more money than I wanted to spend for 8 bends, but screw it, now Ill have it.

That's a good reference. Much more comprehensive than the instructions that come with the Ridgid 600-series benders, which are pretty much a copy of the Swagelocks.

Exactly the decision I ended up making. More than I wanted to spend, but I have it now. And have used them quite a bit since the original project.

Itll be like anything else that once you have it you find (make) more reasons to use it.

That's pretty much my reasoning for everything in the shop.


SwageLok says the following about their bender.

Quote:
"Cannot be used for 2507 tubing over 1/4 in. or for medium-pressure tubing."
2507 seems to be some Stainless Alloy "Duplex stainless steel is comprised of austenite and ferrite in an approximate 50/50 split. Super Duplex 2507 is a highly alloyed, high performance advanced form of this material."

Medium pressure is a thin walled stainless tube.

Quote:
"Medium-Pressure Tubing FK Series
Cold-drawn 1/8-hard tubing is more robust and allows for reduced wall thickness and enhanced flow through the same diameter tube. All Swagelok medium-pressure tubing is marked to indicate size, material, condition, and heat number.

Specifications
Heavy-Wall Annealed
Material 316/ 316L stainless steel
Pressure Rating 15 000 psig (1034 bar)
Sizes
1/4 in. OD, 0.095 in. wall

3/8 in. OD, 0134 in. wall

1/2 in. OD, 0.188 in. wall
Cold-Drawn 1/8-Hard
Material
316/ 316L stainless steel
Pressure Rating
15 000 psig (1034 bar)
Sizes
1/4 in. OD, 0.065 in. wall

3/8 in. OD, 0.083 in. wall

1/2 in. OD, 0.109 in. wall"

Where does NiCop fit into this?

This alloy is approximately 9.2% nickel, 1.4% iron, 0.8% manganese, and 88.6% copper

Looking at the Fedhill site typical wall thickness is 0.028" regardless of OD.

I think those ratings are for maximum capacity - they do not speak to the minimums, which are a bit more subjective since they depend on how much flattening you can tolerate for your application.

I will be very interested to see your results with the roller version of the bender. If the bend radii are the same, I don't know why flattening would be significantly different between the roller vs. wiper style benders. The devil is probably in the details.

The 600 series bender came today. What a super nice bender. It even makes the nice 400 look crappy.

I tested it out quick (no pics as my phone was dead) and was pleasantly surprised to see a much nicer bend. The outside was hardly flattened at all. The smallest OD I measured was 0.350"

Nice! I wonder why having the rollers makes such a difference in bend quality. The 1/2" version of that bender is on my wish list...the radius is quite a bit tighter than the die I have for my bender and would come in handy for a lot of stuff.

Try just a bit of lube on the pressure shoe and see what happens.

Unfortunately I already shipped the 400 series bender back. And I still havent snapped a pic of the bends using the 600. Maybe tomorrow night.

Last week I stripped the first section of the floor and applied two coats of the master series silver prime. Im still very impressed by this stuff. I actually hit the subframe with a metal faced hammer getting it in for a test fit and it didnt chip.



Last night and today I finally tackled the fuel hard lines. About all thats left is to do a couple small bends at the rear end and flare them. Im not running them all the way to the back as there isnt a great spot to connect them to the soft lines going to the surge tank because of some additional bracing im planning for the subframe, and with everything so tight back there I wanted a nice easy spot to access them. The soft lines should be more than well protected in the rocker area and above the subframe.

If I hadnt mentioned it before this is 3/8" NICOPP and im using stainless rock guard over it.





I really wanted to use two straight fittings here, but there just wasnt room. Also I obviously still need to work on some clamp mounting for the soft lines.
