The angle of any cutting edge is always a balance between durability and economy. Shallower angles will require less energy to draw the individual cutters through the material, that's a win from that point of view but but the leading edge is less well supported meaning it is vulnerable to distortion and damage which is bad In short, there is an advantage but there is a price to pay.

Sounds like we have a caravaner in the house. :laugh1:

What he said This accelerate out business is BS of the most dangerous sort, largely propagated by caravaners with their extensive road experience

Sounds like the spool you are using isn't going closed centre or is passing oil Is it from a loader? might be the wrong type?

Take it and get it bead or sand blasted, or, you only need a small DIY type blaster, a full on hydrovane unit will be too much. Rinse and dry then lacquer the inside if you are particularly keen.

Quite right, although it would probably be more accurate to say, although they do now technically have a degree of separation they are still urinating in the same container

I don't think it is a conversion. You wouldn't want a line trimmer with the turd flicker pointing up :thumbdown. I suspect the thinking behind the angled cutter head was to have less teeth in contact because of the lack of power. I cant see any signs of what would be obvious traces of modification. The caster isn't a caster, to be that, it would need to be on a swivel, as it is its just going to be a hinderance to operation. Nether does it look to be a depth gauge, it would be in the hole the grinder made so that wouldn't work. The fact that it has a mechanism to get it out of the way while in the operators position speaks to it being a transport aid. Its a PP design but as you say' as long as it was cheap......... No idea on manufacture but belts and bearings will be available from a decent engineering factor and those look like bog standard finger teeth to me Carlton / Rayco Type Straight Finger Teeth

Its quite impressive that it can be used that close to traffic and pedestrians without showering the world with dust and chip (lack of TM notwithstanding!) There are others of that type that use an auger and reduce the entire stump to "chip" without the core to deal with.

This..........

Well it easier said than done:laugh1:

Just before it looks like that one:laugh1:

Nope, that's called viagra:laugh1:

And yet she managed to survive the trip, and spread the chip in a greenhouse. Did you consider they might have used polly bags rather than have it loose in the back of a car?

Don't you need salt with the chips and vinegar?

You were doing well till you said that. That just says I CBA doing the leg work. Make the time to watch the vids, there is plenty of good and bad practice out there in YouTube land, decide for yourself what's good and bad practice. There is probably more to be learned in how not to ....

Casting tends toward granular structures and probably isn't the best material process for making spikes. Spikes (climbers) are more usually hot forged

The upshot would be. If anything goes wrong, it's all on you. The people at fletcher Stuart would ( quite rightly ) be able to say you weren't using it in the prescribed manner and any misfortune was therefore your issue. Bear in mind that the pukka kit is cheap as chips and waaaaay easier to handle

We (read, I watched a plumber mate) make a "spud gun" powered by lighter gas but it was a tad powerful. It was a hoot, but who wants to be retrieving a throw bag from 8 or 9 gardens away?

I await the results of your investigations with baited breath

Just out of interest, where is that written?

The chrome remains "as is" and is incorporated into the remainder of what is fairly low carbon steel. It isn't strictly correct to describe it was an alloy, it would be best described as mainly steel of a slightly better than average carbon content with inclusions of other materials. For it to become a true alloy you would need a lot more heat and probably some flux to bind the slag which would give you some sort of ferrochrome or possibly stainless, depending on the ratio of materials. Forging saw chain gives a good decorative effect that some will call damask but metallurgicaly speaking its no where near. Its also a PITA if the edge has a chunk of chrome in. Better as a "wall hanger" than a working knife. File teeth are hot rolled to shape the then acid etched to give them the edge, the etching is a cold process and if they aren't too badly damaged files can be re etched to bring the edge back but AFAIK this hasn't been common practice since we entered the disposable era, etching is pretty much the only way to edge a file. As far as analysing alloy content with any accuracy goes, expensive terms like gas chromatograph spring to mind, probably not cost effective unless you definitely had to know, you can pretty much tell what you need to know when you get it on the anvil

Reality calling What we have here is an unsubstantiated allegation if an activity in another country.

I would be thinking Robinia

I am sure they cover Lichfield Seriously though, don't you think it would be better to just ask NPTC direct or perhaps bring the matter to whatever trading standards organisation exist in Gib?

Can you prove this allegation? How does this stand with regard to jurisdiction?
