Thread: CS Milling 101, Hints tips and tricks

Guys, seems like there are a continual trickle of newbies posting their milling setups and it's great to see the addiction continues! Most of these folks seem to be milling small logs on their knees on the ground when there is no need for it. Yes I do occasionally mill (big ones) on the ground but I'm wondering whether a sticky on milling positions would help these folks, that way we wouldn't sound like broken records?

Allright guys. For the sake of keeping this an information thread, lets keep the banter to a min and keep the sharing of info and your set-ups flowing.

My tips for Alaskan style milling
1) Clean the log of as much grit and bark as you can and clear sufficient working space around the log.

2) if at all possible, get the log up off the ground onto gluts or sawhorses so you are milling in as standing a position as possible. You should not have to bend over significantly or mill on your knees.

3) place the log on a slope so that you are milling downhill and gravity aids the cutting process

4) start with a freshly sharpened chain with rakers set correctly and don't let the chain go blunt. Stop and sharpen or change chains often.

5) add extra handles to the mill or wrap handle on the saw so your arms are not spread apart. This allows you to comfortably lean on the mill with straighten arms. The more handles you have, The more variations in arm and standing position you can use which helps relieve fatigue. Add anti vibe grips to handles.

6) If you are milling over about 24" in width consider adding an auxiliary oiler to the outboard end of the bar to protect the bar and chain.

7) add rollers or wheels to the inboard side of the mill that makes contact with the log so the mill does not constantly jam up against the side of the log

8) use log rails that are longer than the log so that the mill can perch on the end of the log while the saw is being started

9) on really hard wood, if the log is partially dry, remove the first 6" or so of the starting end of the log, so you are not cutting into dead dry wood where you lose 90% of the chain sharpness.

10) when finishing a cut, before stopping the engine let it idle for 30 seconds or so, so it can cool down a bit .

11) orient the milling so the saw is downwind of the operator to reduce exposure to exhaust and sawdust.

12) stop to admire and chimp the wood grain often - remember you will never see it looking so vivid and natural again, EVER!


Things to watch out for
a) the CS bar and the CS milling rails not being parallel to each other across the mill. This will cause the mill to rise or more likely dive making it harder and harder to cut. This can be cause by poor construction or dropping or damaging a mill.

b) loose nuts/bolts/bits on the saw and mill. If they fall they are dangerous if they hit the chain and you may never see them again amongst the piles of sawdust generated by milling. Check all fasteners and use Loctite where appropriate.

c) loose mill/bar bolts. If you forget, the chain could be toast in fractions of a second.

d) PPE. High quality hearing protection is even more essential than regular sawing because of the prolonged exposure. Consider using 30dB+ muffs.

e) pushing too hard. If you have to push hard, something is not right usually its just 4) especially the rakers not set properly but occasionally its a)

That will do for now!

How about some recomendations on chains and chain set up. I currently use plain stihl chisel and it cuts fast and relativly smooth. What are the pros and cons of different set-ups?

Bob

You hit on every point I have posted in the past. I found out all of this the hard way 10yrs ago.

1. Wear a dust mask
2. Put wedges in the cut so the bar does not get pinched

Generally I use granberg milling chain. Works well.

I have used normal stihl chain in the past. More vibration in the mill. Cuts rougher

Another thing to keep in mind is saw maintenance. Milling is way harder on a saw than normal crosscutting is. Check and clean filters often, Max out the oiler on the saw and use an auxillary oiler if possible, Let the saw idle for a little while before killing it to allow it to cool, and always keep the chain sharp.

All good points gentlemen.

Doh - how could I forget the wedges!!!

Dust mask is good too. I have a full filtered air mask - helmet - muffs combo that is very useful for dry logs but mostly where I mill where there is almost always some breeze which helps enormously.

How bout some pics of your set-ups.....I know when I was hot and heavy into milling, I was always thinking about.....

Getting my logs up about waist high.

Getting the first cut square and smooth and keeping it that way the length of the log.

Then theres always the different types of chain and what angles work best in particular types of wood.

I did this as an example of how I set up the rig. I haven't actually milled a log in 3 yrs. No point when I have 3000bf of oak, cherry and walnut laying around. My wife hates it when I bring more home.

Once the rig is setup I set the mill at 5 1/2" and mill away. This is quick and easy. The 2x4's I use are 8' so I cut the log at 7' so I have 6" of overhang. As a woodworker to me an 8' log is meaningless. I almost prefer a 6' log. A 6'x20"x1.25" wet board weighs is starting to get heavy for me.

The only way to raise a log to any decent height is with a bobcat or tractor or a group of really strong men. Otherwise you are SOL. Most of the logs I mill have been in the woods so a tractor isn't excessable.

It depends how crafty you are.

I got this log off the ground.


With this.

Full thread here.

The jack lifts 7500 lbs and cost me US$30 and modifying it took a couple of hours. Admittedly It's not something I like carrying more than about 100 yards but otherwise it's well worth the effort.

I have a jack like that. We used it at the apple farm back in the day. I will use that next time. You just got the wheels rolling in my head on this. I can raise a log now

Thanks
Chris

Basic setup - sorry if I keep posting this one but it's the clearest picture I have.

Unistrut log rails


Another basic setup using a ladder as log rails.


Boomerang shaped log



Another tricky to start log


Small mill with Homelite 340.


Serious sloped milling - mill went down by itself!


16ft cedar


Enough?

fantastic pics bob

Good stuff!! So far all Ive milled is pine logs and its very easy. For this I use regular chisel chain sharpened to 10 degrees and rakers down to .040 all by eye. Most of my logs have been out in the woods where its hard to get heavy equip. When I fell my trees I put down some logs crosswise, I have these leftover from the previous tops. As the tree lays naturaly off the ground with limbs supporting it its easy to stuff some more logs under before limb-ing and bucking log lengths. Then I'm up off the ground a couple feet from the get go. As you get close to the bottom cuts of the cant, these pieces, and the leftover pieces from making the cant, this wood becomes liftable. Then I made triangular pieces to prop these off the ground. They dont roll and they are light wieght and do the job. With this pine obviously I start on the uphill side of the log and she just chugs down thru with almost no effort, same with the mini mill ( I could even run the mini mill one handed ) One thing about the mini is to make sure you get it squared up good because it is adjustable (slotted holes). Obviously all safety gear is a must.

If you guys do a search under my name of threads started in the milling section...theres quite a few with good pictures.
