|

|
I've got the Alldays gearbox totally dismantled and after serious cleaning I've spotted some areas that are probably porous so I started looking for solutions.
First I spoke to a local company who do vacuum sealing and I was less than impressed with the foreman's attitude towards the job despite his boss's enthusiasm so they're off the list.
Next I spotted an advert in the VVC's magazine for stuff called X-seal which claims to impregnate the metal by capillary action and seal it up permanently. At under £30 delivered it seems like a good option to try and I may even be able to treat the engine block/sump without dismantling.
I shall report back once I've had a chance to try it out.

I'm wondering if you can vacuum a local casting void with a vacuum cleaner? The aero boys just use a plastic bag and some sticky strip like bubble gum. They use it to push glued panels together, but also to anodise undersides of wings. I know a vacuum cleaner doesn't pull much, but a 50% vacuum below the glue would pull resin into the void.

Is this also a possible solution for pourous blocks on the p38 engines ?

According to their website, yes. I'm not sure about it until I've tried and tested it.
