Sperber Chainsaw Mill with Two Stihl 076AV Chainsaw Engines
This is a fully working pair of 111cc Stihl chainsaw engines powering a highly adjustable Sperber planking mill. As a furniture maker, I used this for a number of years to plank a variety of felled timber as an economical way to source hardwoods. It's hard work and requires two people to operate it, but it can produce very cheap planked timber. The effective length of the bar between the mill uprights is 36", but 30" is probably nearer to the maximum practical width of timber that can be cut with this unit.
The Stihl 076AV engines are incredibly powerful chainsaws, producing 7hp each, so aren't your average garden firewood saws. They do, however, work really well at the job of ripping through tree trunks. Two ripping chains are included. Both saws have recently been stripped and cleaned, and start within a couple of pulls.
Also included in the package is a 30" Oregon bar, complete with cross-cut chain, that I used with one of the saws to fell or trim timber before planking.
You might notice that one engine has a cut-away sawdust guard. This avoids clogging of the leading saw with sawdust and was strongly recommended by pioneers of chainsaw lumbermaking. Neither of the chainsaws has a chain brake system as these are unnecessary when the saws are used in this way. Two spare sawdust guards, a couple of spare air filters, one or two other spare parts, together with a copy of the 076AV manual are included as well.
I have also copied a few articles which relate to chainsaw lumbermaking and am happy to supply plenty more information on the use of the mill if you're unfamiliar with how best to set everything up. You'll need an aluminium ladder to act as a flat surface to guide the first cut. There are lots of videos on chainsaw lumbermaking on YouTube to give some guidance, but none that I can find which shows the Sperber double-engined mill at work.
You're welcome to pick this up from Ivybridge, Devon, or I can ship it out, disassembled, by TNT at a cost of £39 to anywhere on the UK mainland, except the Highlands and Islands.
