3120 on Pro Cut mill a work in progress

View attachment 231335

Saw mill with barn in background that was cut on mill. Lumber was tornado blow downs that people wanted moved from their yards.

Have had mill a couple of years now and been making changes as I get a chance to make improvements while still getting some lumber cut.

In progress now is modifying carb by adding a 3120 h adjustment.

Working on trying Stihl pmx chain as Logosol has introducted thru Baileys the pmx as available for up to 36" bars.

When the carb is checked out and fully functional, Then changing to a higher limit coil or an unlimited one.

thats an awesome setup you got there my friend...i have a nice 20' track leftover from my old ross bandmill i want to build a procut design roller setup on it for my 084..the saw is currently setup in a alaskan mill which i love but for some things i would like to have it on a track.i want to design it to cut tapered live edge siding...but anyhow i'll stop rambling ...nice setup would like to see more pics happy cutting p.s good job building the barn from repurposed logs better than them getting thrown away

reclaiming some down cedar

Local cemetery had a cedar down. Will use it for counter tops for my wife's sewing area and for our bathroom vanities. Have used cedar for the doors on our house and for our kitchen cabinets.

wow those are some amazing cedars ...i used to climb and prune lots of tree's in cemetary's and i used to see some of the best tree's there...every once and a while i would come a cross some real nice burl's there too..anyways nice logs

Good cedar logs are a major find. I'd be interested in your opinion of the Stihl pmx chain-- and photos of your mill in operation. Thanks for the posts.

a few sawmill pics

View attachment 231443View attachment 231444View attachment 231445View attachment 231446

Photos from left to right. Top bar oiler, Machined from alum. I have read where some have trouble with bar hole getting stopped up. Have not had any problems when hole is drilled at the very back edge of chain slot.

Auxiliary oil and gas tanks, old lawn mower tanks.

Scale set up so when cant is flat side down, cuts can be calculated from the top so last piece is what you want it to be. Also, log dogs are marked as to height above zero so when they need to be raised, chain height can be referenced to dog height so as to not cut dogs.

Dogs are cranked in by a threaded rod. I am not happy with the way they work and I have an idea to use a tongue jack that has side crank and moves 10" and does not have much slack up and down as my present system does. Right now we are using the tongue jacks to put down 1x6 t&g flooring. Jack the boards together as some are bowed or worse. Works great on the floor so I hope it will work on the mill when the floor is finished.

Here is a sample of some reclaimed cedar. I built 5 doors from down cedar from a farmer friend's pasture.

Carb mods finished, H jet works

Have been working on adding H adjustment to 3120 carb. Got it working today. Didn't work right at first, but had to go back and make a change after advice from a member on chainsaw form. (some pics on chainsaw forum as well)

Linen cabinet for our bathroom in our new house. Eastern Cedar milled on Pro Cut, dried, planed on 12 1/2 planer, first cabinet job.

Beautiful work.

What do you have for a 12 1/2" planer?

 

[lps8]

planer

Hello gemniii

My planer is a Rigid from Home Depot made by Ryobi. It is a 2 blade, the newer ones are 3 blade. It does pretty well. To finish off, I have an open throat drum sander that will sand up to +- 40" and I have a da sander for finish work. I used the drum sander to sand edge glued panels such as the inserts in the piece you see in the photo.

Working on trying Stihl pmx chain as Logosol has introducted thru Baileys the pmx as available for up to 36" bars.

PMX is lo-pro. Not recommended for 120cc saws and requires special sprockets.

Not much advantage to the PMX/Granberg grind. It was Will Malloff's 1st design for ripping chain. His 2nd design cuts faster.

Envy your cedar.

Thanks for the advice.
I realize pmx is lp. Baileys sells it thru logosol up to 36 bars. Rated for 100cc, so I thought I would push the envelope a little With a 32 bar to see if I could get a little more speed and a smaller kerf. Supposedly stihl links are a little heavier than other lp. will see. Have 15 reg 3/8 mill chains to go back to.

Bailey's logosol guy said it will work on a reg 3/8 set up. Had seen the same conclusion elsewhere. Supposedly a little mismatch, but will still work. I'll keep u posted.

I have been experimenting with a roll of LP on my 441 and after a couple of hours of use my 050 GB bar sprocket is fine but the 441 has started to really mess up the drive links. This means the 3120 will shred the drive links and mangle the sprocket. I have to run the chain really tight on the 441 to stop it from jumping the sprocket. That chain won't make much difference in softwoods like cedar as your 3120 is chain speed and not power limited. If you want more cutting speed try higher raker angles. You should be able to run 10º in small cedars.

Nope, it will ding the drive links. Some people get away with it, probably because their bar groove is wallowed out enough to swallow the dinged links.

I've broken lo-pro on an 84cc saw.

Simplest way to cut faster is to grind your 3/8 chain the Malloff way, and experiment with more aggressive rakers.

Hello Bob, really appreciate your craftsmanship and fabrication that I have seen in you posts. Most of my fabrication was blue flame (torch and welder), but in recent years I have gotten a mill and lathe that I am learning as I go.

I just received the pmx chain and an 8 tooth sprocket today. I also wanted to try the 8 pin sprocket to see what that would do.

What is wrong with this picture? Is there something I am missing about the chain and sprocket. It looks like it should work????

I have run reg 3/8 chain from 0* to 30*. They all cut. I was looking for a thinner kerf, also. I am going to do more serious timed study on different chains, sprockets, unlimited coil, etc. I want to maximize my cutting with what I have, then all that will be left to do is saw. Playing will be over. Have plans to build a small cabin from pine sawed on the mill.

I have also cut the rakers down and also cut them down at an angle as I had read somewhere. I just need to do a little better record keeping to see which changes are worthwhile.

If I were to get serious about mini mill production, I would get the Lucas mill, but I don't want to work hard enough to make make it pay for itself. I have a house boat to build when I get this house done. Then some bass fishing.

Thanks for the advice.

Hello Mtngun,

Appreciate the input, but I have the same question for you that I had for Bobl about the chain and sprocket. Do you see anything wrong with the pics in the post above. Or do I just not know what I am looking at?

What is the Malloff way?

I have plenty of 3/8" chains. I have 15 for my mill, but I am trying some new things to pick up some speed and was looking for a thinner kerf. Might not be any better, but enjoy learning new things.

Thanks.

Well, I answered my own question. I found the info on the madoff way to sharpen a chain. Looks interesting.

[BobL]

You picture looks exactly like what mine used to look like.

You see those little red lines they are not all the same length.

This means only one drive link is taking the cutting load during that half turn of the sprocket which places a large force on one drive link instead of across several several links. This stretches the chain very fast and within a few minutes of operation the chain stretches so much the link at the exit slot of the sprocket prevents the link at the entrance slot from entering its slot and the chain will jump the sprocket.

some wood for the mill

Future work.

Neighbor called to ask if I wanted a few pine logs. Had heard I had a mill and wanted to give them away. Only a 1/2 mill down the road, so took tractor to load and trailer to haul and picked them up.

Now, just need to get house ready to move in so I can do some other things like sawmilling.

Will try to do some videos as requested when I start.

more lowpro stuff and pics

View attachment 233838

Pic of Stihl low pro after being run on my 3120. It has been used enough if there were a problem, it should show up. It was used on a fairly well used 7 tooth sprocket and a 3/8 Carlton bar. The grind on this chain was a standard grind, not a rip grind. Chain was comparable time wise with a reg 3/8 chain with a rip grind as per Will Malloff, as suggested. Like the Malloff grind. Will use it for a while and see how it goes.

Have some more things to try, but so far no problem with the low pro. Have not tried the rip low pro from Baileys yet. Don't know when I will get to as we are getting close to getting finished enough to move in our house.
