cutting up triple tree to make clip ons
« on: May 01, 2013, 08:47:21 AM »
anyone heard or done this before. I was thinking of instead of ordering 80 dollar clip ons for my cb350f that i would take the extra triple tree or lower triple tree and cut it up and weld on some handles for some DIY cheap clip ons. What does anyone think, think this was be safe assuming the welds were quality?

i would actually cut off the parts myself and just take it to a machine shop and tell them i just want them to weld on some 7/8 steel bar at the certain length and angle i wanted. So the time will be worth it. I think itll look fine to me. Until I want to spend the high dollar and buy some nice ones. I am mainly worried about the safety aspect, does everyone think they will be safe?

Do you think any machine shop will do it for under 50 bux?. Some wont even touch it once they find out what it is for.

seems like time and money wasted to me, especially for a part that once you mod, use and remove it, will never get used by anyone again.
a triple could get used again.  sell your triple to fund getting a nice set of tarozzi's  ;D
do it right the first time.

The concept is simple enough, but the lack of adjustability and the question of trusting the safety of the welds makes me want to recommend against this type of modification.  If you can perform your own quality welds, then maybe, but most welders that can perform quality work are the same welders that ask questions about what its for, and from a liability standpoint it may be hard to find someone to do it.  Real clip-ons would be a better investment of your time and money, at least that's my thought.

I will ask the machine shop how much it'll cost and then make a decision. I live in a small town so I don't think it'll be a problem, plus the guy who owns it I taught his daughter last year. How much could I sell a triple for?

Perfect example...

I trusted a local machine shop to shorten my kick/side stand.  After over a year, it just SNAPPED...for no good reason.  Well...the good reason was that they just cut it clean and welded two blunt ends together with no reenforcement or "V" cuts.

Luckily...someone was standing next to the bike when it happened and caught it before she hit the ground...shwew!

I'm over the whole DIY, part-making thing.  I like to build / assemble...but as far as MAKING parts....I'm leaving it to the pros from now on.

Please don't take this the wrong way but. You ask about safety.
 What does the price have to do with it? or the size of your town/

I threw that in because people were talking about liability and cost.

I think safety is an important factor. I wouldn't want to be the guy whose poorly fabricated pseudo clip-on snapped mid turn and dumped me into oncoming traffic.

Clipons just aren't that expensive. I just did a quick check on eBay and there are many available for $50 and under. How much cheaper could the local shop be $20, $30?

Personally my limbs are worth more than $30.

Bottom line, would the experienced guys here do it.? NO
What could possibly happen.... Well you could grab a hand full of front brake and have the clip on snap off in your hand sending you head first down the road.....   Doesn't take much rational thought to know what you should do......

Been there done that.
Nothing was available for Harley V-rod when it came out so we machined spare top yoke and welded 1" bar to it
No problems at all in several years (drag racing)
I didn't weld it as I don't 'do' alloy welding but would have no issues doing a lower with steel
With CB 350, main issue with using lower is the weight, using top probably isn't smart as they are known to crack if overtightened
I fake being smart pretty good

the idea is sound BUT

the top clamp is aluminum.

You will have about an hours shop time minimum for the welding.  Good luck finding a machine shop/welding shop that will charge less than $50 an hour for labor (you will also have money in materials too)

Its cast Aluminum guys, they are already prone to breaking and are not the easiest thing to weld properly.  Clip ons are a piece of cake to make out of mild steel, why the hell would you bother with 30-40 year old cast aluminum...?

Have some made like this..?  or just buy them...

CycleX have them for $69.95  which is probably around the same price as having the tree cut up and used except CycleX has to stand by their product, i doubt anyone will using those old clamps...

the fortunate thing about Clip Ons is that if ONE fails...you've always got a back up.  :)  :)

I think you are right, but for the effort i would still get something better....   Frank, you could probably make a steel set in the same amount of time....

Its been done. The only reason I'd advise against it is because it isn't cost effective if you have to pay someone else to weld it. I think welding the mild steel lower tree to handlebar tube would hold fine, but I'm not as jaded as some
