File reco for 92x pro axle?

[Redstone Racing]

I purchased some cheap files from the hardware store to notch a groove in the 92x pro axles to prep them for bending. Per 5 Kids' post I started with a v file and switched to a round file. Then I bent them in the Axle bending tool I purchased from DD4H. What I quickly discovered is the 92x pro axles are wicked straight and HARD as can be! What kind of files are you guys using? The max speed on my Dremel is 10,000 rpm. Would a more powerful Dremel make this process easier? After bending 4 axles (with only 2 being acceptable) I need new files!
Thanks!

The method I use requires a steady hand and a careful touch. I use another Dremel with a grinding wheel at the lowest speed setting available. With both Dremels spinning I then carefully touch the area on the axle I want to make a groove, it takes about 2 seconds or less to create the groove I want and I'm done. Caution though, one small slip and there goes a good axle. Works for me but use at your own discretion.

I do something similar. I use a hand drill mounted in a Max-V vise operated by a on/off foot switch. Spin the axle in the hand drill and then use a dremel with a cutting wheel spinning at 10K rpm to cut the groove. It helps to have a magnifying glass lamp to see what you're doing.

Awesome idea!

+1 this is how I do it also.

That's the way I do it also. You have to have a very steady hand, I hold my breath as I dremel it , so I have no slight movement. Have not damaged an axle as of yet

Although it doesn't matter, I know a good place to buy a replacement/images/boards/smilies/wave.gif.......SPIRIT.......

will the vise and screwdriver trick still work to bend the 92's after cutting the groove or do you need the bender.

 

[cygnus]

I've never been good at the vise, screwdriver, hammer trick...so I'd recommend the bending tool.

I saw one of those benders and they looked really nice hope one day I'll get to put my order in for one.

Still use the vice, hammer, and screwdriver. for making grooves, either get the ones from DD4H that have the groove or I have had success with a hack saw blade against a mounted dremel.

Wouldn't a hacksaw blade create a square bottom groove? And wouldn't that create a fracture point in the groove and weaken or fracture the axle after bending? A rounded bottom groove would have a fillet radii in the "corners" and be stronger as no point of fracture would be present. Just thinking out loud.

I use a drill file when I do it, chuck the axle at the point you want the grove then you can use the chuck as a guide. Start with the edge of a good flat needle file to start the groove then switch to the v or round file, use a slow speed so you don't burn your file or axle. I also use the vise screwdriver and a vise with soft jaws.
