Extending Bars

is there any ways to extend bars? just a couple of inches? like 2. my apex bars are just a tiny bit too short and they hurt my back but i love them so much. robert was telling me that i could shove forktube in there and leave some sticking out and then weld some standard bar on. would this work? are there any easier methods?

Lol there are like five responses above you telling you what to do.
Anyway, 1.5 inches is a little shady. You are gonna want to either do more, or cut your bars shorter and weld them a little higher up. Your slit would end right where the weld is if only do 1.5 inches, and that's bad.

Taper them, but you'd have to go at least like 3 inches higher to have space for an hic shim. You could just taper them 1.5 inches higher, but they'd only work with scs

I wonder if it's really not self-explanatory...
tapering:
You just buy some OS tubing(I.D. 1-1/4", O.D- 1-3/8"), the min length is ~90-100 mm (depends on the height of a hic shim), you need about 30mm(1"-1.5") of overlapping: for instance, your bar is now 53 cm high and you want it to be 57, you have 10 cm OS tubing, so you should cut the bar to 50 cm, slide the OS piece 30 mm up and weld it
That is for HIC

As for SCS, e.g. again, your bar is 53 cm, you want 57: the overlapping is the same, but you won't need to cut the bar, so you should buy 7 cm of OS tubing
and you better weld it spot by spot on the opposite side(as far as I know, welding in one stroke may bend the metal a little, 'curve' the steering tube)

ok let me just explain it again. right now my bars are 19 high out of scs with NO slit. i am wondering if i can extend them with out making them oversized. just a couple of inches so the weld is just above my scs. or if its the only way i could taper them to oversized but i'd rather not.

If you want to keep the bars standard size then cut a few inches off the downtube and then weld on the extra length you want, this keeps the welded area away from the slit.
I would recommend tapering as it will be stronger and its no more work than staying standard.

yes, i know lol so i just get the dimensions of the OS tube that lumpy gave me and get 1.5 inches of it and then weld it to the standard bar thats it? it might sound stupid but can you weld on chrome? and is there any way i can taper them while keeping them standard?

Weld on Chrome: Chrome is a plating so you would need to remove the Chrome plating at the joint that needs welding.

Do you actually have chrome plated bars?

any way i can taper them while keeping them standard
No-taper= gradual diminution of thickness, diameter, or width in an elongated object

If you want to keep them Standard size then it is a straight Butt weld and welding 2 sections of thin walled tubing is not a very good ideer for bars.
mr H can probably do a competent job but doubtful anyone else around you could. At least not anyone that is affordable.
ideally you would want a smaller tube inside the Standard bars so that the 2 sections will sleeve over the inside tube, , drill some holes in the Standard bar tubing so you can Plug weld through the holes on to the inner sleeve. which acts as a reinforcement.

As you can see this gets tricky rather quickly.

The other problemo is that you need 4130 tubing in Standard size-for the extension as well as a piece for the inner sleeve. 4130 is not sold at the local hardware store or Home Depot.

By the time you get all of the components to extend your bar height and pay for welding you might as well just buy new bars.

If you can weld then this will save you money.


Tapering from Standard size to OS is easier since you can slide the OS tubing over the standard bar tubing and the process is so much easier, if you can weld it or get someone to weld it for you.

Edit: I guess iffin you wanted you could use a piece of OS tubing to sleeve the OUTSIDE of the standard tubing butt joint.
