roller tip replacement

[mike031]

I was wondering if anybody had replaced their own bar tips. I purchased the tip allong with the rivits. I was going to dill out the old ones and use either a press or a hammer to put the new rivits in. could somebody tell me what might work or how it is done properly. I would think their is a special too,l but im sure their are other ways to do it too. thanks

I drill halfway through the rivet (being careful to stay centered) with a bit that is slightly smaller than the rivet diameter. I put a thick washer under the rivet to support the bar -- the washer hole should be just larger than the head of the rivet that will be driven into the back-up washer. An anvil is ideal, but any heavy, solid chunk of steel will work. Use a punch just smaller than your drilled hole to drive out the rivet. The clinched end will shear off at the fist good hammer blow. When clinching the new rivets, I put a steel backing plate against the rear jaw of the vise and clamp the bar in the vise up close to each rivet in turn. This insures that the joint is closed tightly before the rivet gets clinched. Use a flat punch and clinch with many sharp blows with a lighter ball peen hammer, working your way around each rivet.

Rivet drilling requires significant skill; you must stay on center or you will booger up the hole and make it unusuable for the original size rivet. It may take some individuals quite a few spoiled rivets to get the knack of it or you may get it right away. It just depends on you. Rivets are best bucked with either a squeezer ($$$) or a rivet hammer (NOT a air chisel or zip gun) and bucking bar. Since these are kind of specialized and pricey tools, it does not make sense to buy them just to do this.

Any aviation mechanic is required to know how to drill and buck rivets. A lot of guys in auto racing have these skills, too. You might consider enlisting help from someone involved with airplanes or race cars. These guys will have the above mentioned tools, too.

Just take a punch and hammer the old rivits out, if this exceeds you skill level, have a neighborhood kid come over and do it.
The new tip comes with new rivits, just use the same hammer you used to beat the old rivits out, to beat the new rivits in.

I would just grind the old rivits on one side and get a punch to get them out. Then I would just use a hammer to put in the new one.

You really can't grind the rivits unless you have a tiny little grinder. They're resessed into the bar. Just use a punch, bam, one or two hits they're out.

I just use a hammer and punch. works fine for me.

Here is what the Oregon manual says. http://www.oregonchain.com/tech/ms_manual/ms_08.pdf
I think the most relevant info is on page 7 and 8.
