Use 2X4

Drill hole in 2x4 3/8" +. Put 2x4 in vise --- pull tubing through hole. No brainer and it works.

I seen this video back before I made this thread, they weren't available yet at the time though. However I seen them on ebay just recently. They are made specifically for different size of tubing. Around $70 shipped on ebay.

Found that I had other things to accomplish before having to worry about fuel lines. Well I'm back to getting fuel lines done and I have made the tube straighter as seen here.

64 Comet Build for Sema.....Its build time.... - Page 17 - THE H.A.M.B.

Not sure who originally came up with this idea for a straighter cause I have come across a few other threads on different forums with the same design.

Anyways with the suggested pulleys.

The tool would work with smaller diameter tube, but with 3/8in I would need different pulleys.

Small scrap piece sitting in the rollers. The tubing is too big, I think for it to be effective the tube needs to be able to actually sit inside the wheels, not on top.






I would need pulleys that look more like this, but these do not seem like they would have bearing centers in them. So the design would need to be changed and the wheel would need to be sandwiched like they are in the picture.

The groove on these look like they would work with almost any diameter of tubing. They pulleys look like they have a similar groove like the $200 tool in the picture in POST # 15. The brake quip tool.

EOD Guy I do believe this is what is in the pictures, and they have bearings in the bore.

ogre i bought straight ss tube in 5 foot lengths, same for my brake lines
rarely do you need more than 5 feet before you need a fitting for a fuel filter or a brake fitting
lot easier than dealing with straightening coil stock

for most applications you can tell where coil stock is used
i think straight lines with uniform bends looks better

kso I have had the task every now and then of straightening coiled wire...thousands of feet of it...and built a special tool using bearings with adjustability everywhere that works OK. The worst problems are that the material wants to flip around in the rollers which is solved by forcing it to run in the groove of a large pulley it's natural way first for a couple loops, then formed straight right off of that, and then varying tension creates varying results.

How that relates to tubing? Hmm...probably not exactly, but before I built that I tried something simple that worked OK when just doing a little bit. The material was held in a vice so it didn't flip around, and then a simple tool using wooden dowels (1" dia.) placed to work the material similar to the schemes above was strung along by holding it against the material then walking backward from the vice. You adjusted the angle you held the tool at to suit. For tubing, something made with straight pieces with radius cuts would probably work better, note the material is being forced to slide along the wood without benefit of bearing which may actually help control a little bit.

This wouldn't be a better tool, just a quicker one. Twenty minutes with a drill and table saw should get it built, and a little wax on the wood should prevent scratching the tube.

Maybe I'll try that later and see if I'm full of cr*p or not! Mostly I just uncoil tubing against the floor but no, that doesn't straighten it all the way and I have to finish it across my knee.

plattted Stainless steel is very brittle and hard, does not take lightly to bending then re bending.

plattted Try harbor Freight, they have rollers separate from the tube roller machine and can be purchased separtly. looks like the McMaster site is a good source, however.

Rex Stevens If you use different size inner bearing races,you can pick up junk ones from electric motor repair shop,cut the outer race in two places,the bearings fall out and you are left with unhurt inner bearing race

Tube Straightening Metal Rollers - SOURCE

Looks like the metal ball bearing groved rollers that are attached to the channel iron in the tube straightening photo are from "Sliding Screen Doors". These metal ball bearing rollers are available at most local hardware or HomeDepot stores for $2.00 - $3.00 each. Hope this helps.

Rell.....If you are interested in a tool like this, PM me. I can make you one fairly reasonable.
