Recovered the dead mower battery! Cleaned with bicarbonate of soda solution about 10% bicarb. That reacts & cleans all the cr@p off the plates. Then filled with 12% epsom salt solution and trickle charged for 24 hours. Up to about 13V and starts the mower no problem. That's with the Epsom salt...

A bit late.....its back together with rivnuts and M4 bolts! On the mower and first cut done:

Thanks. I was planning to MIG it. Labouring the point here I know... I'm struggling to see a way to build up the weld on this rotted half without say inserting a brass round the same diameter as the bearing to weld against. I drilled the spots out with a 4mm drill. I only went thru one half...

@bertsmobile1 evening, still undecided on how/if to repair this corroded half of the pulley. Do you reckon, rather than rewelding it, I could bolt together with x3 M4 bolts?

? Luckily it came with two bottles of grit! Just got to find the other one! Worst case I find another bottle style. These Lidl Parkside tools like the sand blasting gun are one off special deals. Rarely repeated. Zero chance of spares etc.

Whoops...I cut the bottom off.

It was suggested this might happen. One school said gravity would overcome the potential issue. Another predicted it to a tee. So @tom3 wins tonight's star prize! ? Little video link: Seems all too familiar for some reason... ? The Lidl gun kept clogging. Haven't drained the air tank for a...

NSK 6203DU so nothing special. The two halves will need another dip before painting. Off to sort through the bearing box...

@bertsmobile1 you're dead on there! Just out of the acid and what I thought was resilient material around the bush is in fact the blown seal of the bearing. More obvious the other side where the seal is more intact. Pulley is indeed in two halves spot welded together. You can just see one of...

Managed to get the tensioner pulley all apart just now, some more chipping and scraping and back in the barrel for a final 24hr dip. It's salvageable. Bushed rather than a bearing again just like the plastic one. The bush sits in some resilient compound like on a suspension arm. A bit of zinc...

As aforementioned I've put the gearbox back on (pre grit blasting / painting it). As much to test it out as get SWMBO off my back! Brake assembly swapped from my mower to the new gearbox. Drives forward and back aok. 1,2,3,4,5 and reverse all there after some playing with the gear linkage rod...

Won't the mass of medium above in the "hopper" mean that the main, horizontal air flow through the bigger diameter barrel strips the medium as it drops into the barrel? One way to find out!

Just read you said sodium bicarbonate! It's washing soda crystals I have here bought for electrolysis derusting. Someone else pointed out that might not be the best blasting medium :eek: I drew up the assembled gun/adapter/pipe junction in CAD and had my lad 3D print me two halves to clamp the...

I remember the lectures as an apprentice about "gas gangrene" from dirt and grease pushed in through cuts or bodily orifices etc by compressed air ?
