Frustrating milling experience, need backup saw

[Can8ianTimber]

OK so some of you may remember I posted about buying a 075 a couple weeks ago. Well Yesterday I went out milling with the 3120 and got two feet into the first cut and reallized the chain break was catching a little bit. It made the clutch smoken hot. This is the second time this has happened due to the stupid way it has an external clutch and the chain break is part of the removable cover. Anyway after it cooled off I went to put the cover back on and tighten the chain and the chain tention screw broke. ARRRR, well I was still able to cut up the firewood sized stuff and get a trailer load of wood but how frustrating.

Well this has really got me thinking about needing a backup saw and this is where the 075 comes in. So could the 075 handle the 84" bar? That bar is a stihl mount that I just use an adapter to run with the husky saw. I am assuming the 075 runs at a slower speed since it is an older saw so that would be good. I know bob used to run a 076 on his mill but I don't know how long of bar he had on it. I am sure that it would be fine on the 50" or 60" but they are Husky mounts so it won't do me any good.

So far got the piston freed up and I should have it running soon with any luck.

I cut off the chain brake on my 2100 with a grinder. Problem solved!

Here's the 076 with the 60" bar milling cutting a 42" of really hard wood.

The biggest I have cut is 48" of really hard wood.

It's not gonna break any records on your 84" but it will still cut.

The 395 I have has that same style chainbrake. They are a PITA when milling. I have also had the chain adjuster screw break on me as well. I now keep a spare one in my kit. With my 385 when I have the twin powerhead setup put together there is very little clearance on my mill. Since it is an inboard clutch and a different style brake flag, i discovered I could take the actual flag completely off the saw. There is a metal tang that the flag fits over that actuates the brake. this stub is only a couple of inches long and it is very easy to engage and disengage the brake using it.
Maybe you could modify the chainbrake flag so you could still engage and disengage the brake but have the clearance you need for the mill? Cut it off or heat it and bend it? I know I like being able to engage the brake when I finish the cut and pick the mill up of the rails.
As for the 075 being slow, does it have a rim sprocket? My 076 does. So a sprocket change from say a 7 pin to an 8 may be in order. I haven't milled with mine yet but have sut some big rounds with it and it is slow ( but steady). I believe you could have an elephant stand on that saw and it would just keep chewing thru the wood.

Good luck with it.

Just realized you said 84 inch bar not 48. Probably don't want to try the sprocket change thing just let the 075 grind a way. If the saw has good compression and is in good shape then it should pull the the 84 inch fine. Just slow.

I never had that issue when I had my 3120, worked like a charm, except the one time when the bolt from the muffler bracket vibrated off and bar oil went everywhere. But it was nice to have my 066 there if something did happen. Kind of miss that, but the 066 has only ever had two major issues while milling, one chain adjuster, the other was the prior owners muffler mod deflector fell of and started melting the chainbrake handle.

Stuff happens.

8 tooth sprocket for 075/076

I have an 075 that I'm setting up for milling, I've not tried it out yet and the saw still needs a little work. I'm looking around for an 8 tooth sprocket but all I'm finding are 7's. Any tips on where to look? I'll be starting with a 36 inch bar and have a 42 in case I run into anything really big. I've read in a number of different places that the 075 is too slow with a smaller sprocket.

Thanks guys, I am really exited to give it a try. Here is the bolt, I managed to get it out of the cover so I can try and find something similar at the hardware store so I can go take another shot at it tomorrow.

I also did take the chain break band off. Since I have the 372xp now I don't think I am going to be using the 3120 in hand held use.

Also just for kicks, here is big brother and little brother, I think they look cool with both having cannon bars.

Thanks for the help guys, I can't wait to get the 075 working and give it a try.

Try Bailey's they are a site sponsor here. The other place I would try is Madsen's.

Just a hint: replace that little rubber/plastic square washer thingy that holds the tension screw in when you replace the screw. If you don't, you'll be replacing that screw again very soon.

My local Revell hardware store that is a Husky dealer had that screw in stock.

You'll probably need to find a rim-drive drum and then get an 8-pin rim sprocket to fit that.

An 075 will pull any bar a 3120 can and more - it'll be slower in smaller wood, but I would hazard a guess that it might even outcut it with a big 84" bar, though the chain profile would need to be modified to take advantage of the torque.

I had this happen to me yesterday. I had my 32" bar buried in a 5' across Siberian Elm and the chain adjuster / tension screw broke at the pawl on my 395 during the cut. I didn't think I was putting to much leverage on the saw. What caused this?

 

[woodsrunner]

I don't really know, but, I suspect they just aren't strong enough. This is the only issue I've had (on this saw) where I think the part on it just isn't stout enough. Mine broke when I was tensioning the chain. Maybe it was already cracked? I guess the simple solutionis buy some spares and keep them with you. Of course, a totally excellent toolmaker Like BobL, could probably whip up a much better replacement in his shop.

I guess to be fair, when mine broke I was trying to tension the chain on a 60 inch double ended bar with a second powerhead on the other end and the whole thing was mounted on the CSM. So I could have over stressed the little guy.:greenchainsaw:

I bought a rim drive drum and 8 pin sprocket from Baileys last January. They don't list them on their web site but if you call them up they will hook you up with the right parts for a fair price. For 9 or 10 pin sprockets you will have to try Madsen's.

I searched every hardware store and husky dealer in a 50 mile radius and could not one that had that part or something that could substitute. Going to order 2 of them tomorrow morning from balieys.

Here are a couple pictures of the haul from that same tree. These are the limbs from the tree that broke the saw. This is once I got them back to my property.

I got one trailer load of firewood (about 2 cords), one load of limbs and I will go back and mill the 3 largest peices that I could not get out in one piece. I made a little trailer out of an old moble home axle and pulled it behind the quad and then pulled the logs up on the trailer with the winch.

This is the 3120 with 60" bar ready to make the first cut. This is also about 3 minutes before the chain tentioner broke and made me switch gears to hauling the firewood and smaller logs.

I just remembered when my chain tensioner broke, I was able to keep milling. I used a pry bar (VERY GENTLY) between the case of the saw and the mill uprights to tension the chain and then locked it down with the bar bolts. It worked; IF you try this be very carefull! It was a saturday afternoon fix. Monday I had a new part.
