>Bob, in the post above, which visible surfaces of the plane in the first photo (#4?) have the Oxpho Blue treatment?

>As these tools mostly work outdoors, I use Oxpho Blue on almost every piece of steel or iron in the shop.

Works on the cast iron used in planes just fine.

>Hi Bob,

Very well put. Sounds like youse guys who live in harsh environments may need different methods of protecting your tools from rust, but I bet the view from your front porch is probably better than mine:-)

>I live in the city during the week overlooking the mighty Hudson river. This Ole Gantry used to supply food and other assorted sundries to most of manhattan in it's day. Not much to look at anymore.......atleast to some. It's supposed to be restored shortly and I'm hoping to get inside for a look round

>....you mention it. I read somewhere that phospheric acid is used to treat steel to keep it from rusting. Well, I've built a few buildings and they don't call it red iron for nuttin'.

BTW- the red iron (tube steel) on top is called grey iron...go figure.

>If I remember correctly phosphoric acid was what was used to prep the steel in the fish holds of some of the boats around here after the coal tar epoxy failed due to nicks,chips or dings.

You`d needle gun the rust blisters,apply the acid and then re apply the epoxy over it.

Talk about nasty stuff,try welding on a bulkhead that`s been painted with coal tar epoxy.It does look alot like jappaning when new though.;^)

>I was not clear.

You wrote, "I prefer to leave the phosphate surface on everything but the sides and sole."

Did you apply the bluing to those two surfaces?

BTW, I guess that this "bluing" is grey, right? That is how it looks on my monitor.

Thanks Bob.

>I blue everything after phosphoric acid treatment and buffing.

Lapping the sole and sometimes the sides removes the blue....it's a better index fluid than Dykem or Prussian Blue.

Sometimes I reapply it to the sides if I did any work there just for rust prevention.

Soles I generally wax.

The 4 1/2 in the pic is entirely blued....different iron/steel formulations come out slightly difefrent colors....cast iron greyer and tool steel bluer.
