Thats the thing. Sorry forgot to paste it in.

 

Hi CUTTER that's a great book mate thanks Jon

Thanks guys, that's really helpful, I'll have to get a copy ASAP as I've got to work out what we felled last year as company comin to shift it are sayin there's about half the weight of what bottom estimate was at time of felling😕

 

Did you fell, convert and leave? That's where your weight's gone. Ask for weight ticket or sell by volume; what's it going for?

Yeah felled n left for owner to deal with this time last year, p r infected on scottish island with no roads! Think it's goin to BSW atFort William for milling and chip, lots of big e larch (50/60cm and larger DBH) and a lot of younger hybrid (25/35cm DBH), I didn't realise it would lose so much weight but owner is havin problems getting it shifted as big firms sayin it may not be worth their while, but surely volume is the most important? In the past my guesstimates have been reasonably accurate. We did the job on a day rate and they want us back to do the rest of the larch and also some monster Sitka, wrc, hemlock (see avatar!) as now it's been opened up storms are creating havoc.

What's the volume in the job? If you're looking at sawlog in the sizes you mention, you should be able to move that on volume (top diameter) instead of tonnage...

If you can get a decent top diameter out of those bigger Larches then ie 30+ you should be able to get some longer length logs out that are more in demand. Can you not sell on top diameter volume for sawlogs? That is a monster tree in your picture!!!

There are literally hundreds of lengths at 5m with that sort of top diameter and a lot more that could be cut to whatever length and still achieve 30+, one of the guys who've been to look said that 5m was too long for larch as it moves so much when milled, were fairly sure a lot of the bigger stuff is European larch as was lighter coloured wood which I've been told is higher value and more in demand for boat building.

The biggest problem is getting it off the island ie cost of building pontoon for the timber barge, which I think would have to be Troon tugs Red Princess (all way out of my league!)

There are some huge and rare conifers there as one of the previous owners was one Cpt Swineburn who brought trees from al over the world and established a pinetum. There's a group of 4' dbh Sitka that well be dropping next time, and i think they'll lose a lot of specimen trees to winds as more works carried out😢

5m makes fine 4.9 / 16' sawlog assuming the timber is straight* and knot free enough?

 

Sounds like lorry loads of material for a sawmill, not a small concern.

 

Could still do with a handle on the overall standing volume that was cut and is on the ground in front of you...?

[timbernut]

Yes mostly lovely straight and knot free primary and 2nd and some 3rd lengths, surprisingly few with rotten butts.

Only about 500m from mainland but road wouldn't cope with the timber lorries so barge (think it takes approx 800t) only real option.

Worked out before that wed felled about 4/5t per hour and can work it out more accurately now I know vol to wei ratio as I know what numbers of what size trees in a daily basis. I'll put up a couple of pics when I'm back laptop ( now on the lash in Sheffield woohoo!)
