todays job has been cleaning out the oilways in the barrels after being vapour blasted... To do this properly and get every last bead of media out I removed and replaced the core plugs... they are cheap to buy. There was a surprising amount of crud behind them... Made a couple of stepped punches so I could drift them in nice and square.
Checked the bores for wear, there simply isn't any! Ground the valves in with some fine paste (how old is that tin of grinding paste ��) and checked I had a continuous seal with a sharpie pen. Gave the guides a quick clean with the burnishing hone which just removes carbon,
Finally, a good wash in petrol the tray and a check in the bottom for any blasting media. My mate who builds automatic gearboxes gave me the tip on the stainless steel trays... you really can see any debris in the bottom!
