Re: Black Oxide

If I am not mistaken, during the bluing process, some water will boil out of the mixture causing the concentration to increase thus a gradual temperature increase as the water/chemical ratio changes. Would not be a problem for first time use, but if the same solution is used repeatedly, water will n...

Re: Black Oxide

When you mix the chemicals and the water, quite a bit of heat will be generated, so I would recommend slowly adding the chemicals to the water,not the other way around. Also, I don't think the exact proportions are all that important because there a many formulas for hot bluing floating around. I ha...

Re: Worthy Afternoon Project

I recently made a tapered octagon barrel for a muzzle loading pistol out of a piece of an old Martini Cadet barrel. I did it with a set of vee blocks and two pieces of 1"x1"x1" aluminum bar an a piece of threaded rod (small enough to go through the bore). Drill and tap the two aluminum blocks. Turn ...

Re: Backhead Wrapper

Fiberfrax can be purchased from Aircraft Spruce & Specialty Co. It is relatively inexpensive and comes in 1/16" and 1/8" thickness 24 " wide rolls. They will sell it by the foot. It is used for aircraft firewalls and can withstand tremps up to 2300 F. Hope this helps.

18 years later

Here are a couple photos of my on and off again efforts at constructing a live steam locomotive (3/4" Rob Roy). I intend to run it to get the bugs out before painting. If that takes as long as building it, that may be some time. As I had no track and lacking patience, I put it on the workshop floor,...

I suspect the correct word is "castellated" and not castle

Single Phase to 3 phase

A recent poster said "do not switch the VFD output in any way between the VFD and the load motor". I recently purchased a 110 1ph to 220 3ph VFD. My intent was to use the VFD to power 2 - 3ph motors. Not at the same time! Rather by using a manual disconnect whereby I would unplug one motor and plug ...

Reginald Van Gleason (AKA Jackie) used this same method to have his Martini's delivered back in the 50"s. "MMMMMMBOY that's good Booze" would be his comment along with a role of the eyes after a delivery! Rick

I have used Sulfuric Acid ( approximately 10 % solution)and it works just fine but you must be careful. Now, when I am siver soldering small pieces I just take some household vinegar and mix in some salt and it works just fine also. In my opinion pickling after silver soldering is not an exact scien...

I asked the question because the Golden Gate Live Steamers specifically state in their safety and operating rules that "Side Saddle" is required. I am 68 years old and am about to complete my 3/4" scale Rob Roy and for me it seems that straddling would be easier for me, but if it is not allowed, "so...

small gauge riding cars

It seems to be "common practice" in the US for elevated track riding cars to be ridden "side saddle" while in Europe it is more common for the rider to sit with his legs on each side. Can anyone shed some light on what the reason for this difference is? Is is for safety reasons, or something else. R...
