Hi, i'm looking for weld up a gate using round tubing. Just wondering if there is any tips or tricks on cutting 45/90 degree angles and matching it up to round tubing?

My gate will be made out of 2 1/2" round tubing. thanks for any advice

The easiest way is to flatten the end of the abbutting piece and cut your angle on the flat part.

I like a drill press and a hole saw....

Captain, what size holesaw for 2 1/2" tubing? 2 1/2"?

Dang, to get a flat end, just heat and hammer it flat?

Thanks

slit the stiles...
flatten rails...
insert the rails into the slits...
weld...

use a hole saw and cut a concave end on the rail...
use the sane size holesaw as the OD of the tubing...
butt  the rail to the stile...
weld...

mame sure there is a vent hole in the rails to allow the welding gasses to escape so you don't blow out the weld as yur welding..

draw a picture??
you can't be seroius???

the horizontal pieces are the rails...
the verticals are stiles...

lay the rail on a piece of steel and smack the end with a BFH.....
rotate the rail over and smack that side...
keep at it till ya have pinched the end of the rail closed...
if you hit one side and then the other you will get a nicely closed up end...
hit as often as required...

if you have a press ... flatten with that instead...

let's just say that the flattened end is 2" across and 3/8 thick.... (yur actual may vary)
drill 1/2" hole in the stile aprox 2" OC on above the other where you want the rail to be...
use yur trusty jig saw with a metal cutting blade and conect the holes...

the more faster easier way is to use a right angle grinder with a cut off wheel to make the slots from the get go...

insert the flattened of the rail into the slot and weld it up...

if you miss the slot size or it's some place where it shouldn't be... don't sweat it....
you have a welder... you can fix any booboo ya make...

practice on some scrap....

most pipe and tube will have a seam runnung the length of it.. use that as yur lay out reference...

sbishop,

Do you have a metel cutting bandsaw? Or a chop saw like this?
You can cut the angles you want easy.
To get both ends the same, just cut one, measure the length, and put a level on the first cut to line it up before clamping.

Drill press and hole saw is the most accurate, but scroll about 3/4 of the way down the page in the link below and you will find the quickest

you can take a sawzall and cut a V that is close.  I'm am not a fan at all of smashed and welded gates, they are MUCH weaker than one that is kept round.  take the pains, and notch out the tubing, and it'll hold up to climbing and driving the truck into it :)

I've not tried the 45 degree shopsaw trick in the link, but I will next time especially on heavier pipe....

  What I do is just use a piece of square tube for the ends, and cut your pipe square all the same length, and just butt the pipe to the square tubing.

I used a free program called winmiter. You input the details of your pipe and it prints out a full size template. You then wrap the template around your pipe end and cut the pipe to match. I used my Bosch jig saw with a metal cutting blade and a grinder. I now have a plasma cutter and would most likely use that. Its really quite easy to do. They also sell pipe wrap templates at welding supply stores.

Here is a picture of the gate I made at the entrance to our woods.


sbishop

That Winmiter program is the way to go, thanks for all the reply's. I'll post a pic when it's done!

Bitternut, you have a close up pic of your hinges?

Thanks

bitternut

No I could not find a closeup of the hinges but if you are not in a big hurry I can get one in the next few days. I made them using solid round stock welded to the steel posts and the gate. I drilled a hole through the center and used either 3/4 or 1 round bar stock for the pins. I don't remember for sure what the sizes of the material is. I also put grease fittings in them and give each one a shot of grease once a year. Gate works great...........very solid.

sbishop

i'm going to weld one up next week, so I have lots of time. if you can get a pic of the hinges that would be great!

Thanks for you help

I may have missed it if it was posted but you guys ought to be using the hinged jig that is made for exactly what you are aimong to do. My photo stuff ain't workin right now or i would post a pic but they are stocked in every welding supply in the country.

you can notch the end of the pipe by cutting angles on the end.

hears how to do  it

Didn't find them in your gallery. ??  ??   ::) ::)   ;D ;D ;D
And I bet they are good too.  :)  As was the quote I found in your other post. Thanks, it's a good one.

Kevjay,

those hinged jigs look like they would be the Cat's pajamas!

I don't know of a faster way. About 3 seconds to trace the pipe and 15 seconds with a cutting torch if you are slow, and you are ready to weld.

I guess it comes down to how much you want to invest in tools. I have a bi-metal (use lots of oil) hole saw set for 3/4"-4", a joint jigger (sort of expensive), and 12 ton tube bender.

If you want to do it cheaply and still have a fairly nice fishmouth, get a compass, draw your circles on cardboard, cut out, transfer to your tubes with magic marker. Then get a skill saw with a METAL blades (the ones at Home Depot are okay) and cut them out (slowly). Just make sure the blade does not hit the inside of the pipe. If the blade is too long when the Skill saw is in the extended position, just cut the blade end off until it fits inside the pipe, IF it can't fit though both sides at once.

A 6" metal blade should be fine though if it is 1/8" mild steel tubing.

You mean a jigsaw or saber saw right?

Got my gate all welded up, works GREAT!!!!!
