Your right there Mike, I think Graham is Raymond Babbitts twin

All the outer casings in the crate to take to the acid strippers tomorrow. Hopefully they will be back in about 2 weeks.

Whilst waiting for the engine cases to be returned from the acid strippers, I have been ordering the parts I will need for the rebuild.
One of the items I now have here is the primary drive chain. I posted a photo of the original primary chain and Oddjob suggested I put the old chain next to the new to show the comparison.

Original Hy Vo chain fitted to the engine.

Now the original next to the new Hy Vo

There is no damage as such to the old chain but it's lost it's structure just through normal  wear.

I have also now got the head stud to replace the one that had to be mullered to remove it, the new supporting grommets for the oil jet tubes that spray the camshaft as one was broken, the other was very brittle also so decided to replace both. Have got gasket set, engine oil seals, cam chain etc etc etc, so gradually collecting all the bits I need.

For those that have never seen a Hy-Vo up close and personal, this is what it looks like.

Cor blimey, don't these things take a long time. In my head I wanted to have this engine rebuilt by now......but back I the real world my engine cases have now been acid stripped. This has removed all the old paint and oil, just a quick blow over with the soda next week sometime to remove any corrosion and they will be ready for painting.

Some pics of a few of the bits.

More progress. Main cases painted and cured so I can start rebuilding the bottom end.

Looks nice.

That's one of the best bits I think, starting the build with things all clean any prepared.

That looks good if it’s not top secret what has been done to get to that condition

No secret. Hot wash to remove all grease etc.  Acid dipped to remove all old paint / oil. Another hot wash. Soda blast and hand finish to remove any old corrosion that may be left in the nooks and crannies. Painted with engine enamel, air cured for 24 hours then final cure in the oven. The good outcome is definitely due to the prep.

No, that will never be as good as my Hettie. Sand in the sump, people will not learn

Julie, was final painting farmed out or DIY?
