Re: Ospho Question

On cast iron the reaction is very vigorous and a layer of foam is likely to form. I suspect that the reason for this has to do with cast iron being somewhat porous.

On the other hand, the reaction on steel is much slower. If there is a layer of foam that develops, it is insignificant.

Re: Ospho Question

I've used it as a primer on rough pieces such as battery holders, chassis parts, etc. For cosmetically important items, such as body panels, I've followed with sandable primer, wet sanded, then top-coated as usual.

Re: Ospho Question

Ospho contains phosphoric acid but it also has a number of metal "salts" in it. They seem to be a vital constitutent. I've coated steel stuff with phosphoric acid to remove the rust and as an experiment I didn't rinse it off. Within a couple of days the item was covered with a heavy layer of red rus...

Re: Attn:CP-173 Builders

Walt Disney believed it to be the most beautiful locomotive ever built. Apparently, it strikes the came chord in other peoples' thinking, too. I'm one of them.

Then, press Ctrl-V to paste the image into your editor. Use the cropping feature to cut away all the superflu...

Re: Eye candy lathe

It's a beauty, all right. I've seen them in action, being green with envy, all the while. Here's one that's similar:

Re: Moryia fan finished, finally

I'm sure a link would be acceptable. IIRC, I've linked it.

Hmmm, maybe I'd better check, just to make sure.

For those of you who haven't been there, I highly recommend you spend some time at Craig's site. Follow his restorations of some huge old iron and you'...

Re: Moryia fan finished, finally

The RPM of the fan depends upon how much heat is applied. The alcohol burner keeps it running at a nice, satisfying speed and creates enough of a cooling breeze for demonstration purposes. I estimate that my "show" speed is around 300 RPM. Whatever it is, it's comparabale to similar fans I've seen, ...

Re: If somebody sent you these pictures, (1)

I once bought a large lot of tools from a retired master machinist. I thought the way he priced them was fair. Both he and I were happy. He looked up the current list price for the items, cut that in half, and that's what he charged. Granted, he probably got more than he originally paid for some of ...
