Restoring Rusty Mouldboards.

Aye-up,

I managed to buy back a plough my Dad used to own. It’s a KV LA8NR 3 furrow reversible.

It’s only maybe 40 years old but has spent over 20 years sitting outside. You can imagine the state of the mouldboards. Anything I try and buy is too long. The Spaldings chap said he spoke to KV direct but they don’t supply that type any more.

We have lightly sandblast them but there are still lots of deep pits. There’s no way they will scour, especially as coarse abrasive sands are in short supply round here.

Anything that can be done? I’ve called a couple of metal polishers but they don’t seem interested.

Cheers, Pete.

Flap wheels are the best way. ones like this https://www.metals4u.co.uk/tools-eq...lap-discs-zirconium-welding-abrasives/56763-p
for the big angle grinder are quicker 60 grit to 80 work up and down vertically so that the lines such as they are that are left are with the flow of the soil over the mouldboard iyswim.
if theres deep erosion they will be there for awhile, im afraidd else you will have to grind away the whole board :oops: but to a degree, aslong as its shiny enough carry on using ...... they might even scour better for it, .
after be religeous about oiling or greaseing them after work of course to save time next time.

What are the bodies/ mouldboards aamoi ? what about this lot for pattern ones /supply
:unsure:take a trip to Germany :cautious::D

A box of flap discs and a week end in the shed
3 boxes. Coarse, medium and fine.
1 box dust masks
and a dry weekend just ouside the shed with a crosswind.

You'll be glad it's not a 6f by the end of it.

+1 for flap discs, or shot peening to take out the imperfections.

Clutching at straws, some kind of 'plasma coating' to resurface the boards? likely megabucks and furrowed finish.

Best bet, keep asking around until you find someone with 'new old stock' boards on a very dusty shelf, and hope they honour the original price of £1/7s and sixpence

to use a flap wheel ....'toe tip; the grinder as it comes naturally ..with the flap wheel, like using a grinder wheel on it ,so that the bite of the disc is on one point of it , the front, then you will put lines in one direction , dont try to use the whole disc in one go thats harder work and multidirectional.

Shot blast as you have, as others said flap wheels, I reckon on a full day for a bad Fergie board, then finish off by hand with 80 grit in line with soil flow, always works and we have some soil here that would stick to anything!
If really deeply pitted you can fill with weld, the weld will fuse with the harder moldboard steel, quick grind and good to go.
On one exceptionally bad board I used grinding discs to get the pits out but you have to use them flat.
It is amazing how some boards pit badly when left out and others seem to just surface rust. Most of the match ploughs I've done have all been sat outside for eons.

The likelihood is that they are No.8 mouldboards, mine had them, hence the LA8 prefix. Not too dear to just replace with new.
