If you go to the page with strength results, Mastercraft is almost as strong as Toptul! LOL AND the Powerfist box end is just as strong!

Finally got moved in yesterday and last night the temperature dipped below freezing (-5C). TIME TO INSTALL A GARAGE HEATER! I'll likely be getting a forced air heater running on cheap, Alberta natural gas. My question is: what is the best placement? do I put it centered on the back wall of the...

Square head AKA Robertson scews stay on the bit pretty well.

My Bosch table saw uses a 23mm wrench to fasten the blade.

So, if you can fit in two bikes, does that make it a double garage? Wow, looks great - you sure did a lot with not much space!

Nope. Investment casting is done with WAX! Don't know what kind of plastic the printer uses, but if it is a thermoset it will BURN, not melt! Most plastics are too viscous to be properly drained from an investment cavity.

As you mentioned, It really depends on the part. I cast a replacement thermostat housing for my 4Runner using the broken part as a pattern. The mounting holes just had to be drilled out a little further on the tabs. I moved the pattern around a little in the sand to "Oversize" it a little before...

That was exactly my point! You need the intermediate "plastic" step to "upsize" the pattern! :beer:

If Tang will work, so will Kool-Aid. According to J.A.F.E. The "active" ingredient is Citric acid.

Could be different Aluminium alloys too. Laquer works for a while - cheaper than but not as good as some form of anodizing.

Shrink. The replacement part would be 3-4% smaller than broken original.

I thought Oxalic acid is what was used to anodize (ie oxidize) the aluminium!

Ask an anodizer what they use to clean the Al before anodizing it (I can't remember off hand what the acid is) Are you planning on protecting the aluminium after cleaning it? Aluminium oxidizes fairly quickly.

The forging process is pretty much the same everywhere. BIG hammer hits metal squishing it into shape. The difference is in material, heat treating and design / tolerance checking of the forging dies etc. The lack of quality does not have much to do with The PROCESS of forging because that is...

Done! Finally threw out my $4 gamble last night! I'll hope for some Home Depot gift cards for my B-day and go purchase a new box and breakers after we move!

I was in Princess Auto yesterday and I noticed a new product: Xi-On sockets http://cens.com/cens/html/en/product/product_main_37523.html Are these an old tool reborn? A gimick tool? Maybe not a bad idea? The package claims they can be used on fasteners which are "rounded up to 85%" I thought...

Kind of looks like those smaller ramsets you use to drive a fastener into concrete. The fastener is in a .22 casing, and you hit the top of the metal part with a hammer which fires the nail.

Good information Elroy, but based on the data on the page you provided, you can temper the bearing material above 300F if it is in the quench and tempered condition. You're *probably* OK, but DON'T quench the material in water afterwards. Let it air cool. Wire trays are not tempered steel so it...

You don't need to anneal a steel to change it's properties. It only takes a few hundred degrees to ruin a temper (over-aging, temper embritlement, partial annealing etc etc) -- It depends on the steel but *usually* up to 400F is OK for short periods.

Lowes is only in Eastern Canada for some reason and the Home Depot (Canadian version) does not seem to carry GE either. A quick search online of the other home improvement stores seems to indicate they don't carry them either. Geez, you'd think I live on an island of 10 people in the middle...
