What damage will a railway sleeper pin through a chipper cause?

[arbclimber]

Try chipping with realy worn anvil(s) or rollers, the effect is just as bad as dull blades?

 

Thats the point, anvil will effect performance if, as you put it, they are really worn.

The blades are the same though, get a Jensen A430 and it will still chip with chunks out of the blades, the machine will produce the same standard of chip, put the machine under the same stresses and strains as if the anvil(s) were blunt/damaged/really worn. ALL of the cutting system needs to be good, working condition to chip efficiently and minimise strain to the operator and machine. ??

Yeh, I definately agree that the whole system needs to be in good condition, in order for it to work at its best. Just think that blades make more of a difference than anvil condition.

 

Slightly different point, but still relevant, I think the clearance between blades and anvil is equally if not more important, than the condition of the anvil. I've worked with some awful machines that were completely transformed by setting the clearances properly.

The clearance makes a huge difference, but, quite a few manufacturers dont allow any clearance other than shims which are not the best way forward. Greenmech have the best system, where you never worry about the clearance, it is a much larger gap than other manufacturers recommend. Shliesing system is fiddly and the bolts always seize up, but another good system non the less.

I think we may have just agreed on something then:thumbup1:

 

Not sure how that happened.

You suckered me there!

Doesn't matter what I think anyway, I havent even got my NPTC chipper ticket.

Sorry, I mean I haven't had my LANTRA training for my NPTC assessment for using a chipper:001_tt2:

[Borders Training]

I havent got a NPTC one either!!!!!!

Something similar happened to my T125 last year. Not a railway sleeper pin but something big, metalic and nasty went in. (couldnt recognise the remain after). It damaged both blades, ripped anvil clean off and put a small dent on the inside fan casing. There were a few small gouges on the fan itself.

 

cost was a new anvil (about £8) some new bolts (about £3) some severe blade sharpening (about £25) and the cost of seeing the face of the bloke who had to sharpen the blades (priceless).
