Making chain

[Circle B MN]

Trying my hand at making my own chain loops. Using Oregon 72EXL and an Oregon branded spinner with the "A" bit installed. Works well enough but my rivets get splits around the edges as I get to the point that I believe they are tight enough. Too tight? Too agressive on the squeeze? Non issue?

1. More spinning as you apply pressure.
2. Add a tiny dab of grease on the rivet before spinning.

I've been using 3 in 1 oil. Will give grease a try. I suspect more spinning while tightening is the trick. Thanks.

A heavier oil might work too.

I keep a small, used, prescription container, with a small amount of bearing grease, with my spinner and breaker. I put a tiny dab of grease on each rivet with a toothpick.

I know not about Oregon spinner bit sizes but make sure what you are using matches your chain size.

As Philbert has mentioned, to slow spinning and too much force along with a dry surface cracking the head. The circular marks on the plates show force.

I have just used motor oil and spin fast and apply pressure gradually. You can stop part way on one and start on the other rivet head. After a while you will know how much turning on the pressure range it will take for the rivets and chain you are working on.

I'll echo what everyone's already said about the spinning and oil. I spin it until it's extremely easy and feels as if it isn't doing anything more...then I'll add some more pressure and repeat.

I just flick a switch on the back of the spinner and that governs speed of rotation- a small pump oil can filled with bar oil provides the lubrication- all I need to do as the muppet on the handle is apply the pressure.
The Oregon electric spinner rotates (I believe) much faster than the human powered ones.

Oil and practice, you'll soon have perfect rivets heads just take your time.....and oil.

Use your leading/strongest hand to spin the anvil quickly and constantly and only then apply pressure gently and in stages with the other hand.

I wouldn't get too worried about the cracking.

If you take too long to form the rivet, ie not enough pressure when you initially start off, you can work harden the rivet, and that can contribute to cracking like your seeing.
try using more pressure after the initial few spins, and then taper off the pressure when you have it close to finished.
As others have already said correctly, use oil/ grease too.
