I'd like to visit if you intend using it with a pole pruner

This is what I found, about 30 minutes freehand and it cuts better but not as good as new. I still have a telescopic one to finish but it was so blunt I have resorted to a dremel and diamond disc and will finish with the diamond feather edge. If I were still working professionally I think I'd pay the 40 quid.

FENSA it's a self certification by professionals thing covered by the building regulations. If you diy you are required to make a building regulation notification, same as fitting a new stove, problem is the charge is normally higher than what you save by not having them professionally done. It only really crops up as a problem when the property is sold. I agree with most of the comments about price, our local guy fitted 5 double casement windows in a small bungalow for me in 2010 for £1350, 10 similar in December 2010 for £3270 and 2 more in Jan 2011 for £580. All were fitted from inside without need for scaffolding or ladders but we were left to fettle the rebates with sealant on the upstairs windows.

In agree but buy the replacement while the 254 is still running well, I'm never comfortable going to work with just one saw, mainly in case I get stuck or break a sprocket mid way through something. I never got on with short bars on the small saws for snedding and do use a 254 with 15" bar, I've been impressed by the 550 and 560 but the guys do seem to over rev them to the point of 4 stroking.

Some "man flu" then, best wishes for a complete recovery.

The nut head isn't deep enough to get a good grip so I used an angle grinder to cut out 3 apertures to get a better purchase on the clutch of 254 and 262 (both of which I still use)

Stopping stumps regrowing
openspaceman replied to ajmoore1's topic in Forestry and Woodland management
About the most expensive too! -
It may only be a blocked pick up in the oil tank or even a rat's turd like piece of gunk in one of the plastic lines. I've only had a pump give trouble when a piece of balertwine got jammed in the clutch and stripped the nylon worm gear. Clutch can be difficult to get off if it hasn't been off for a while. I favour a piece of starter cord in the spark plug hole AFTER the piston has covered the ports and then a light tap with a modified socket clockwise.

15kW is about 20bhp. The thing is the tractor is only optimised at about 70% of rated power whereas the 3ph is is pretty good from hi idle to full power at the same speed. I expect the average power of the electric motor will be around 5kW so it will use about 40kWh per day, say £5. The tractor will use about £16 in fuel alone because it is sitting at hi idle between saw cuts.

I found anything bigger than the 4000 just pulled the County backwards. Also bear in mind anything up to the 1184 was only safe to tug 4.5 tonnes of traction. We did have an 8000H on a 974 but the electro hydraulics played up and were converted to hydraulic only. For static pulls the Farmi 8 tonne was better as it acted as its own ground anchor. Be aware also if you add front weight and it still rears up you can crush the bell housing, this is one of the reasons the highland bear had the branch deflectors in tension.

Diesel at best 40% conversion thermal energy to motion and costs ~7p/kWh, electricity ~90% conversion electricity to motion and costs ~12p/kWh but motor has a fraction of the maintenance costs. In practice when using a 10 kW diesel to generate electricity we averaged only 20% conversion. My guess would be a kWh at the shaft will cost between 17.5p and 35p for gasoil fuel and about 13.5p for 3ph electricity.

I agree to send it away to have it re tensioned and gulleted but touching up the top face only with a flat file is necessary between major sharpening.

College or practical training?
openspaceman replied to SteamedTomatoes's topic in Training & education
NO because you may only think you want to ONLY do physical work all your life. Looking back on my life with few qualifications I'd advise get a college qualification and then aim for continued professional development as you work. Many entrepreneurial types will profit with no qualifications, those of us with little commercial flair are probably better off being employed and qualifications are a means by which an employer gauges your initial worth. -

Yes, decent qualifications come in handy if you want to venture into management. -
What are the pros and cons of having the wedge moving on the piston rod compared with the piston rod pushing the wood through the wedge?
-
If the developer has the agreement then the council have to do the maintenance but any liability must remain with the owner I think. Unless no one ventures onto the space the council cannot establish exclusive use and the agreement to maintain would prevent them gaining possession as this would be seen as a licence.

Some of the tropical woods, those known as mahogany possibly, deposit grains of silica (sand) as they dry and it comes out of solution. This makes them too abrasive to mill when dry so they are only milled from green.

I can vouch for one attempting to bore into a douglas resin soaked thigh whilst driving a ford 4000 with tongs. The ovipositor doesn't have a sting but a stinger is a modified ovipositor.
-
NO. Fair enough to borrow (and credit card is a bad way to borrow) if you are guaranteed the work with higher pay to pay it back but never invest on an offchance. Any decent firm will pay for training but expect to have to pay it back one way or another.

Yes Dave bought some of mine when he returned and got on this wagon.

I didn't mean it was the best option but up till 30 years ago English sawmills wouldn't pay much for chestnut ( because of shake??) and then a couple of firms realised there was a demand from Portugal. The interesting thing was that the Portuguese would mill short logs and butt joint random widths for things like drawer bottoms. Also around this period I started noticing pub table tops in chestnut. We were able to sell sc coppice that had gone over rotation length and all the time the bark remained smooth there didn't see to be any shake even on sandy ground and the Portuguese would by sawlogs at 8"qg where British mills would not accept butts less than 12 or 15 "qg.

That's a significant size, 22 Quarter Girth, if they are sound and clean they'll go for export.

Softwood harvesting rates
openspaceman replied to johnnyalpha's topic in Forestry and Woodland management
We sold scots for woodwool (Thermacoust) in 1978 at £19/tonne roadside to Forest Thinnings (Euroforest predecessor). I think cut and extract was £8 then. I think that was the peak period for softwood and continued in decline, especially after 1991. -
I thought the MK was just the 4wd version, it carried on production longer because of military orders.
