[slack ma girdle]

No prob - and please can people give their feedback on the stones - there's been a good lot go out so let's see if they're worth the ££ !!

 

 

 

 

 

Hi Rob, cheers for getting the diamond stones and power pack out so quick. I used the power pack to start my Bob cat, which it did. Sharpened my echo, and charged my phone to 85% before it ran out of juice. Impressed.

The course diamond stone is very aggressive, which given the state of my chain, was just the job. These grinding stones are much longer than the Granberg stones, which is better for sharpening.

So far so good, i will be interested to see how long they last, and keep you informed.

Big 👍 from me too, looks a good bit of kit + it means I don't have to jump start his landrover! ;-)

Question is; could it start the Nuffield?

 

How many amp hours is it? It looks small & I'm a bit confused how a small battery can start a diesel lump??

 

cheers, steve

No one seems to know how something so small can jump start a car?!

 

But they are one handy bit of kit - hopefully they will last well....

 

For us the way they power the grinders is a godsend - no more having to drag the saw to the truck or lug a big powerpack around...

PS - I'm going to start adding comments from here into the product description hence will keep nagging people for feedback

I bought the power pack and the fine diamond grinder bit last week, came following day👍

I've not needed to try the jump start feature yet but have given my phone a full charge from 3%

Sharpened a 36" milling chain today with the new sharpening stone, powered by the power pack.

The stone is a big improvement on the previous type, quite a bit longer which I think helps it run much cooler on the chain. The grinder stone/bit is diamond impregnated steel and holds its profile rather than the other stone bits that wear away and lose profile.

I'm really impressed so far, seems to have speeded up the whole process.

The power pack is really easily connected to the 12v grinder by connecting the crocodile clips over the grinders clips, there's also a set of connectors in the package so you can adapt the grinder lead to plug into the power pack. Something I'll try when I have the time.

Overall it's a great setup, really handy bit of kit !

I used my 12v Granberg sharpener for the first time today (on a mullered 550xp chain on a 15" bar) and the power pack already sounds very appealing.

 

How many sharpens would it do on a 42" Granberg ripping chain? (from a full charge).

cheers, steve

Thanks Si - I'll add your comments to the powerpack description.

Hmm no one knows yet! I suppose because you'd usually only do x1 sharpen at a time... but metal may be hit soon which should get some answers to this question!

Okay..... different angle:

 

so I'm a newbie miller and about to mill for the first time next week.

If I'm milling oak at about 30" diameter , and presuming I don't hit anything metallic.... would I only need to sharpen the chain once during a whole days milling? (based on running a 42" granberg ripping chain).
