Love Casting

oftentimes someone will use a drill size larger than specified or they may intermix threads such as standard or metric. ive never had a properly installed helicoil fail before in aluminum, cast iron, or steel. maybe if its really screwed up i could have a machinist make a sleeve with threads on the outside and threads on the inside to match my bolt , i could have the machinist drill, tap, and install this sleeve for me. i certainly dont want the person who screwed up the helicoil to touch the job again.

There is a larger OD insert that can be used if space allows. It is called a "keen-sert". It will allow you to keep your stock bolt size.
They are not available at your local hardware store but can be ordered as a single item from most industrial suppy, or do a search and order online.
I have also installed a heli-coil within a heli-coil (one at a time with red loctite on the outer insert).

Where I come from, anyone who earns over 1 million a year is rich. I used to be a real estate agent and I knew many people who owned multiple houses and didn’t even hit that 1 million mark. I knew a woman who owned a beauty shop and worked in it every day and she owned multiple houses as an investment. So Obama, a rich guy making well over a million bucks a year, wants to judge McCain for owning too many houses……. I think Obama is being a hypocrite. Until recently, owning real estate was one of the best investments you could make. If any of you can say that you wouldn’t take every opprotunity to earn money if you had the chance (legally) then you can cast the first stone.

Obama wants you to be rich so he can ‘tax the heck’ out of you.
‘let the market work, however way it’s going to work, and then just tax the heck out of people at the end and just redistribute it,” Obama said.’

And actually, right now is the perfect time to invest in real estate.

my boiler has started making a high pitch wistleing noise as it reaches temperature and just before it cuts out. the noise changes pitch if i speed up or slow down the pump. but i don’t think the noise is comming from the pump.
I’ve tried reducing the temperature of the boiler, and bleeding the rads and pump, all had no effect.
I’ve recently added some system cleaner into the system could this be causing it.
It’s a Gas fired cast aluminium heat exchanger boiler and i’ve also got a mains pressure vented hot water tank, standard Y-plan 3 port mid position valve and terrier pump.
Any ideas?

The cleaner has moved something which has moved into the heat exchanger, the whistling is the result of a partial blockage, the heatex does this when it is scaled up. Put a boiler silencer in, and keep an eye on it, this can cause some serious damage.

My husband left my mothers hand me down cast iron pan in the sink one night and now it has rust in it. Does anyone know how to get rid of the rust spots? I tried salt and oil with a brillo pad, and it seemed to lessen the spots but not completely abolish them. Thanks!

coat it in cooking oil, let it sit for a week, then wipe it clean

if its still there, try it again

I was mainly wondering just about shotgun shells, but would like to know if other shells are made the same way

Everyone here pretty much got it. Casings and Hull bases are drawn over a mandrel…

It’s far stronger than a cast product, and far less expensive.

I am looking at a Para Ordinance GI Expert. I know the slide, frame and other small parts are cast. I this inferior to forgings? What might happen after prolonged use? Should I wait for my dealer to get more Springfield GIs (forged slide/barrel) in or should I just get the para.

Ruger has been making guns with cast parts for as long as they’ve been around. I haven’t heard of any widespread problems with them. Thus, the Para should be all right.

If I sand the inside of my cast iron skillet so it’s smooth as glass, will my skillet perform any worse or better?
There’s nothing wrong with my seasoning, I am only curious. My skillet has little bumps scattered on the surface, and it doesn’t really do anything, but I’m wondering if I sand the surface until it’s really smooth and then season it again, will it perform any better? Will it be even more non stick? I know it’ll look really really nice.

Don’t sand it, I never do. I put mine in the oven.

Someone told me that aluminum cookware can ultimately contribute to dementia. That sounds a little extreme and I don’t know if it’s true (hopefully not because I’ve been using that kind of cookware since 1990…)

But if you go with an alternative, should it be teflon coated? Old fashioned cast iron cookware? What (if anything) would be a healthier option?

Old-fashioned cast iron or steel pans would be best.

I use tephon coated for frying, but hardly fry stuff anymore. I had a hard time trying to find stainless steel cookie sheets, had to buy them online.

Aluminum Cookware
Aluminum is in air, water, soil, plants, animals, foods and household products. More than half of all cookware sold today is made of aluminum, usually coated with nonstick finishes or treated in some way to harden the structure and make it more scratch-resistant.

There is no evidence that aluminum causes Alzheimer’s disease as was once suggested by researchers. However, for those who would like to avoid exposure to aluminum, the best way would be to avoid antacids containing aluminum and to use deodorants (which generally do not contain aluminum) rather than antiperspirants.

Many over-the-counter medicines contain aluminum. One antacid tablet can contain 50 milligrams of aluminum and a buffered aspirin tablet may contain about 10 to 20 milligrams of aluminum.

In contrast, a person using uncoated aluminum pans for all cooking and food storage every day would take in an estimated 3.5 milligrams of aluminum daily. However, storing highly acidic or salty foods such as tomato sauce, rhubarb or sauerkraut in aluminum pots may cause more aluminum than usual to enter the food and is not recommended. (These foods will also cause pitting on the pot’s surface.)

Anodized Aluminum Cookware
The anodization process hardens the surface of aluminum cookware making it non-stick, scratch-resistant and easy to clean. Manufacturers claim that a final stage in the anodization process seals the aluminum, preventing any leaching into food. This cookware doesn’t react to acidic foods, so these pots and pans are top choices for cooking rhubarb and sauces with tomato, wine and lemon juice.

Cast Iron Cookware
This all-time classic is strong, inexpensive, and an even conductor of heat for browning, frying and baking foods. Cooking with cast iron also provides a source of an important nutrient. Foods cooked in unglazed cast iron may contain twice the amount of iron they would otherwise.

Cast-iron utensils should be handled differently from other utensils. To prevent rust damage, the inside of cast iron cookware should be coated frequently with unsalted cooking oil. It should not be washed with strong detergents or scoured and should be wiped dry immediately after rinsing.

Aluminum exposures from cookware, of which more than half is made of aluminum, is not well studied, but is thought to be a relatively minor source of aluminum exposures. Exposures to aluminum through food can occur when aluminum leaches or otherwise dissolves from the cookware into the food. Leaching is most likely when the foods being cooked or stored are highly basic (like baking soda) or highly acidic (like tomato sauce, lemon juice, oranges, or vinegar). For example, tomato sauce has been shown to contain 3-6 mg aluminum (per 100 g serving) after cooking in aluminum pans, which translates into about one-tenth of the typical daily intake. This leaching of aluminum with acidic foods does not happen with aluminum cookware that is anodized, or electro-chemically processed to seal the aluminum in the cookware. Clemson University Extension’s Home and Garden Information Center tested different cookware types, and found anodized aluminum cookware to be safe. Regardless, it would probably be wise to store tomato sauce and other acidic foods in something other than an aluminum pot.

Hi all,

I’m trying to work out how to find someone in Lancashire, England who can turn a couple of small plaster casts into something a bit more permanent (ie. metal).

Can anybody suggest how I can find artists or small companies who will do this kind of thing?

thanks

This is work for a Patternmaker, but it is not cheap. A pattern maker will have to make a mould for it, which is made in a special type of sand, then molten metal is Poured in to make it in metal. The cost depends on the design of what has to be cast. Whether it is straight forrward, or a complicated design. Some designs have to be made in two parts and after, they are joined together under a high degree of heat.

This is the fifth step in the reproduction process I use for making my jewelry. After the mold compound has hardened for 2 hours I use a crock pot to de-wax the model before putting it into the furnace.
