Farmertech Pimesaw Head??

[Haironyourchest]

Just broke my Stihl 131 polesaw head again. Cracked at the tightening screws, like the last two heads. I'm tired of this crap, not gonna pay €300+ for a new OEM head.

 

Anyone tried the Farmertec clone head? It's €100 with shipping from China.

Could it not be welded... and strengthened at the same time ?

Difficult on such a small area of thin alloy that is exposed to clamp forces. I'm surprised to hear this has happened three times, I used to be pretty violent with mine and never managed to break it.

Aye, intricate / tricky for sure but not impossible, a dremel would probably be needed to prepare the mount before and dress the weld after, anyway could have 3 goes at it.

Would need a pic to judge properly whether I thought it repairable or which 1 of the 3 would be easiest.. if an Alloy weld I'd probably do it with the steel tube inserted in the casing to prevent it blowing through.

 

It might be a good candidate for trying this HTS 2000 which I've successfully used in many delicate repairs.. just a blowtorch needed so little risk of damaging the casting  so you can have as many goes as it takes till you get it to your satisfaction.

HTS 2000 will successfully join all aluminium alloys, it is the easiest, fastest and strongest brazing rod ever developed! Requires No Flux. Low Temperature. Between 380°C - 408°C...

i think we bodged one together years back with an exhuast clamp, assuming some of the collar is still intact.

I've got it clamped with a jubilee clip, seems to work fine. I might just carry on... Told a lie, it's the second head. Third shaft. First head cracked at the collar after a whack on the ground, on a rock probably. This time it cracked after getting the bar stuck and pulling it around too much.

 

Is it aluminum alloy or mag? I actually have one of those alloy brazing rods, did consider experimenting with it. If I get round to it, I'll post an update.

 

I might just order the farmertek head anyway, as a backup  if/when my jubalee clip bodge fails.

Never understood why  pole saws are so expensive.

You can effect a proper repair with it at a low temp Alloy or Mag.. in fact any metal as long as it's non ferrous, if going to attempt this it's worth having a look at various YouTube vids first, cheers.

Nice one. Yeah I have watched some vids, seems a pretty strong fix if done right. I'll try it, can't make it any worse anyway.
