how do i fish mouth a brakeline

[Rokclod3Krawler]

i just got some brakeline to play with but i wanted to know the easyest (sp) way to fish mouth it.

[CustomCrawler]

I use the corner of my grinder to fish mouth tube. Its not exact but its better than nothing.

Another option would be to use a mill with a bit the same size as the tube.

[Rokclod3Krawler]

if you use a grinder it will make a v cut right? i do like the mill idea but i dont have one...what about a elec drill with a drill but same size....

Jay (ROKTOY) has an excellent general how-to on his site.

OR...

You could send them to Fishmaxx, let him slobber all over'm and send'm back to you.

Either way should work, but I think Jay's way is a bit quicker and, most likely, a bit more sanitary.

First Jason

Second I cut my lips doing mine

Third I now use a dremel and the bench grinder edge

thanks jay's wright up helped allot and has solved fights betewn me and dad on what you can and can not do

It dosn't need to be perfect. The solder fills in the gaps pretty good.

You also need to take the fishmouth into consideration when you measure.

I did some joints on my tube frame using half fishmouths as well.

First off move this to the NEWB section, Then Buy a Dremel and a 1/4" sanding drum or appropiate size grinding drum. I use a bench grinder The corner works awesome.

What about this thread warrants a move to the "NEWB section"?

I wouldn't consider a question about construction of tubers a NEWB topic.

I was thinking the same thing!

Another way is to hold the line in a vise and use a round file. Because it's only brakeline, there's really no advantage to doing this on a mill, unless there are lots of pieces already cut, then a mill might be faster.

For best strength (and looks) you want a good, close fit and minimal joint gaps.

If you've got good drill bits, you can chuck the same size of whatever tube you are using into a drill press and push it against the bit.

Not that great for the bit, but it doesn't use that part up there to cut much anyway

i use a properly dressed (ie: worn down) flap wheel on my 4.5 inch makita grinder works great and only takes a few seconds.

[shutupanddrive]

I use dremel 455 bits. They are a nice diameter and hold up really well. Once my tube chassis and axles are finished I will only have gone through 4 of them.

This is what I do.....works fine.I cut a "V" in the brakeline then use the round file.

[JohnRobHolmes]

I found the mill to take waay too much time for the end result. I touch the edges to my grinder wheel. Not a perfect fishmouth, but it is better than a flat end.

[Double J]

I use my drimil cut off wheel. I start with a "V" then, expanded it out to look like a "U". Then to make it nice I put it againts the proper size sanding wheel. Takes about 10 minutes to do both ends. but has a nice fit against the other parts with minimal gaps.

I use the fine stone on my bench grinder. After you build a few chassis and fish mouth a bunch of tube, you'll find that the corner rounds off and becomes perfect for fish mouthing. Mine come out perfect every time now. I fishmouth one side, test fit, mark to the center to the connecting tube, cut, then mouth it. Done. 45 seconds tops.
