Update on 404 117DL skip and full comp, semi chisel and chisel loops.
This post is a book like a page or three long and then some
The wood is 32" old red oak but green in moisture content @ 40%. Basic chainsaw bar oil was used in these runs milling. Canola oil is waiting to run in the 3ft+ wide white pine I have waiting in 11 to 14ft base or butt logs. Might try to move some of it. It will require running the big Cannon belly bar with 404 @ 167DL's.
Bigger logs of hardwoods are awaiting their turn, soon, now that we have some decent weather here on the swampy east coast.
All info listed here is 117DL's of 404 0.063 unless otherwise noted.
0° top plate angle was/is joke in round file or ground. And yes, I did try reworking the semi chisel/chipper chain side plate, no go. Chip vs dust is a nobrainer. Mike, and others, were right, painfully slow like factory dedicated milling chains and not "that smooth" IMO. 404 full comp semi chisel, full comp chisel or full skip chisel and full skip semi chisel. Never bothered to try any of it square filed with the chisel cutters. I'm pretty sure it was not worth the time to do but the forward bite may have been better and time of the cut reduced slightly
One thing to note my depth gauges are in the 0.035+ range with two thirds of the cutter available. I have been down to 0.042 on the drags/depth gauges with near new cutters.
Two different 1122 powerheads were used during my runs. Both were poly wheel 660's, NOT ported but matched intake tracks, gasket matched exhaust with dual port gutted cans, OEM type screens in one with OEM muffler gutted and the other is a Hyway DP with a gutted can, screens intacked but a bit larger. Saw are the same same for all genersl purposes and perform as such. Base gaskets intacked with Stihl OEM "Stihl" marked jugs. All have a decomp and they are not 066 jugs or Gilar's. My 066 with mods was not used on this setup. It lacks a bigger HD OE oil pump that has yet to show up in the course of six months of waiting. It won't never show so let me know if you have one or the guts for one available at this time, not next year. Please and Thank You. I'm well aware that they can be purchased new in parts or whole.
Moving on
Semi chisel filed round or full chisel round or square filed is slow with 404 @ 10° and not that smooth of a finish face IMO. Not worth the time it wasted but damn, the Oregon 16H took on the nails with no problems in semi chisel full skip or full comp.
12° round ground or filed was about the same as a 10° on all accounts.
I did one skip chisel chain square filed out of the bunch @12° Nothing to report there as expected.
Working back up in angle. 15° 404 round cutter semi chisel was faster than 10° and just as smooth in the face of the cut surface as 10° or 12° IMO. 15° square file chisel full comp was maybe a bit faster than full skip with no real change in durability. The big gain was forward bite. It will almost self feed square filed. RS full and Oregon semi chisel full skip was the flavor of that day.
Maybe more chains should have been tried like full comp semi chisel, meh.
15° or 20° semi chisel round ground or filed 404 is the longest lasting cutter I ran vs the full chisel version....bang for the buck is there. I got two long cuts, 11' 6" logs, hollowin places, no haert wood at one end, with squirel condo's, their "collectibles"
, *s-word, piss, dirt, glass, tarps, insulation, cuts with nails, sand, bla bla bla. Like a Mack truck. Oregon 16H was the loop. Skip or full comp mattered little in da chit. These semi chisel H loops are harder cutters and will be sidelined and saved for messy material or big locust trees.
RS 404 @ 20° square file is the fastest hammer yet! On my mill vs bank for buck and time saved in the cut compared to durability and easiest/quickest to hand file when dull. Um....so stay tuned or KNOT! Nice felling chain also...big chips in old oaks or stumps. It does have major drawbacks in "dirty wood" of any kind. I will refer to dirty wood as, foreign objects or, steel, glass, rocks, sand, plastic, dirty/sandy bark and lighting hit wood as dirty wood. Now, next up is where things get interesting.
25° square filed skip in Oregon, RS or Archer full comp full chisel was fast but suffers in durability vs 20° semi chisel or semi chisel H on my mill in clean wood ymmv. 0.035 or more on the drags had some serious forward bite and the winch was not really needed on a slight down hill run. Up hill the winch helped a bunch on 15° and 20° especially full comp semi chisel round filed or ground. Square file only lasted a bit longer with full chisel cutters but has no durability in nails, rocks, spikes and such junk. In closing all the BS talked up about Square this and Square that is pure BS in dirty wood, sandy bark or metal of any kind. Please, no more rants how great square is. I tests and assess the situation at hand and square appears to not be the ticket unless the wood is pristine inside and free of all junk and/or sand in the bark. It does handle figured or crotch wood better with less drag in the grain changes. Sharpening chain is a poor use of time on site and does little to get things done in the real world of unknown foreign objects. I'm sure you all have Xray vision, right?
Redundancy was intentional to make things cristal clear. Most of what I read or read on the net is clear "ass" mud
So I quit wasting my time and just test my own theories about chain durability vs speed of cut
vs how bad it *f-worded up my chains cutters on the last pass.
Most have not considered six hard passes with any file in any chain takes much long than a quick swipe or two and some fuel to get back up to speed and be in the cut throwing chips again.
Accessory oil feed option were not used on purpose because I felt it was not need with these loops of 117DL and an internal roller nose GB bar. The bar has no burrs or damage or signs of overheating with this setup. Granted that in the long long haul an accessory oil feed system might improve the speed slightly or possibly reduce wear on the chains chassis. I have seen no ill effects to date.
After rereading this last portion it seems a bit jumbled and runs on. I don't really give a *f-word. If you do, move on
Pump gas 89-91 octane E-10 was used to keep it real. 25% VP Full Synthetic FD rated air cooled two stroke small engine oil was used with 75% Supertec cheapo regular two smoke oil and then mixed at 32-1 on full width of this mills cut, notably 33" max width. NO Stihl oil of any kind will ever be used by me in any tool or toy because IMO it is all TRASH!!! I hate their fuel stabilizer, instant headache and many other reason. That would be a whole nutha thread. 33" cut but using 40-1 on lesser width wood around 28" a few times in the mix as it came up to be milled. I have no need for higher octane ratings based on the fact that LL100 is five bucks a gallon here for Avation fuel and just not need with 175 to 180lbs compression. Plus the 100LL does not burn completely IMO at this compression ratio. You can run it if you like and huff the fumes out the exhaust. I have been there and done that. It smeels great when your not wearing your respirator so, enjoy the fumes if you like
. I wear a 3M half face with 100 series filters. Ear plugs with quality Impact Sport ear muffs keeps my sanity till the saw pipes are built, coming soon just to shut the damn thing up. Sound deadening and exhaust redirect is the goal there. I may post a thread on that and/or offer them up after extensive testing is completed.
The saws have suffered zero ill effects and the same rim and rims is/are still going, Stihl OEM 7 pin and hanging tough. I do have Oregon power match rims in 7 and 8 pin I run on the 83DL chains. That is a true 28" bar not the "coolaid" OE one
. Those rims and the saw are just fine with a sprocket nosed 404 Oregon power match bar in 0.063 gauge. That can be run with a stock oil pump if you keep the RPMs up and don't cut Y's or locust. Locust is it's own deal and is dealt with as such. Dry locust requires the fat HO oil system or some accessory oil feed on the bar in anything over 80DL's in 404, umkaaay.
Next up is 3/8" 0.050 in semi chisel, full chisel, three brands, semi skip maybe and full comp backed up with full skip. Need to get some full skip. These loops will be 91DL, 93DL, maybe some semi skip square RSLPJBCB
OCDBADCAD, who can *f-word remember them all, just to see how that rolls. The 0.050 Skweel fat nose 114DL is waiting for it's turn. Thee-eights LP will be the flavor when I get some loops or possibly a roll of sumtin to run I mean burn down. 114DL's is long as I dare with LP or Picco, maybe.
This recording is more for me than you so GFY
Rant done!
