Got myself an SV650 last week, and want to replace the stock can.

Unfortunately the link pipe and exhaust are all welded together, so i have to cut through the link pipe to be able to replace the can.

Would this be possible just using a junior hacksaw? I want to avoid buying an angle grinder if possible.

hi,
yes you could do it with a junior hacksaw.
hope you've got huge biceps, lol
i wouldnt, im lazy that way & like buying tools.
borrow an angle grinder or get a dremel or at least a cheap copy. (i got one out of argos for about 18 quid, lost without it) & cut it off with the supplied cutting discs.
cheers,
GAZ

Or buy a normal size hacksaw,cheaper than a grinder and a neater cut and much easier than a junior hacksaw,once you've actually cut into the exhaust it will go through surprisingly easy

Thanks for the help.

My biceps are the size of peanuts, so i think i will either buy the cheapest angle grinder from argos (15 quid) or buy a normal size hacksaw.

Are you one of these 'gays' I keep hearing talk of?

Razz

Can probably get an angle grinder for £10, but various hacksaws will also do it.
My 9" 2100w angle grinder cut through several layer of thickish steel DNA exhaust like a knife through cheese.

I bought my angle grinder from Argos for £15 and then got a cutting disc for 80p from my local hardware store. It would be a damn site easier with one. Don't be cheap and buy one, they are useful tools.

Give the man a toffee!

Normal hacksaw and you'll be done in minutes.

I did mine with a angle grinder!! Thumbs Up ... but then I did have one!! Wink

I also did it OFF the bike ... if you grind it ON the bike, then put some cloth over the paintwork, swingarm and ... well everything where you will get shavings/sparks.

Its best to dampen the cloth first too ... else you might cause a bit of a fire!! ... so you will save the paintwork and metalwork from the nasty chippings, but end up burning it to the ground when the masking cloth catches fire!! Very Happy

I ruined the kitchen window when I was angle grinding a gas bottle, it's got lots of bits of metal melted into it now Embarassed

I had cause to use an angle grinder in my previous job (was actually for some server rack-mounts.) Left a nice protective metal coating on the wall behind where I was doing it where the semi-molten metal solidified and coalesced.

For kitchen-angle grinding, I do it above our (large, out door style) bin. Generally the food muck seemed to extinguish any small fires and it doesn't make excessively big holes in the bin bag.

I've set fire to my trousers/overalls several times using angle grinders.

One piece of advice I can certainly give you - don't haveyour mobile phone anywhere near when you use one, or afterwards. The speakers in the phone attract the grinding dust and the magnet pulls the plastic bubble down more and more until you can't hear a thing on the phone. Then you have to strip the bugger down and clean the speaker with blu-tack.

Also, close your draws on the tool boxes just below the vice... my screw drivers always end up covered in metal shavings.

Have set fire to my clothes a couple of times too... must remember to change out of work shirts!
Oh and while we're being 'safety nazis'... do be careful... I've ground the top of my thumb off once and bits of skin other times... vice's are good Smile.

If you choose a grinder, which I would, make sure that the discs it uses are wide enough from the centre to cut through the pipe in one movement, this has had me in very awkward situations in the past by literally a few mm.

A lot of the time exhausts especially are shrouded on one side by the underbody/frame of the vehicle, if your grinder wheel is too short, you can't move to the other side.


Not implying you can't judge it, but it's an issue and should really be measured.

Grinding sober helps too. Which I wasn't the other week when I was playing. Ouch. Laughing

While we are at it, wear safety glasses. If you wear ordinary glasses the sparks will melt the lenses.

You need full goggles not just glasses as the sparks will go around the sides. I have spent a few hours in casualty having metal scraped off my eyes.

Your right Walli, in fact I always wear a full face mask. I was just pointing out that normal glasses just aren't up to it, they give a false sense of security. I really like Gs idea, makes good use of the half dozen old helmets I have.

Even when I was p1ssed and grinding, holding the chain near where I was cutting and one foot on the other end, I had my goggles on. Laughing H&S for the win. Laughing

I didn't notice anyone mention the wearing of Gloves whilst angle grinding and the fact that you need an abrasive wheels certificate to change the Disks, but that could just be on Construction sites..

You need to be certified to change an abrasive wheel in industry/in the trade etc but there are no laws whatsoever regarding certification for the regular home user.

Which is pretty daft to be honest, far to many times i've heard of people having serious accidents after incorrectly fitting a grinding wheel. Or even if they have fitted it correctly, they have mis-interpreted the infomation on the wheel/disc, or they just failed to read any of it at all.

Speaking of the certification, i have mine obviously but does anyone know how long it lasts before it has to be renewed?

Use a hacksaw. Wont take you long. Had a bloke turn up at work asking if we could cut a plate for him. it was 25mm thick and 250mm lg. He cut one side with a hacksaw! only took him 1 hour. we put it in our bandsaw, and took 3 minutes to cut the other side Smile

Do you think there should be a theory and practical test for using an angle grinder?
