About 50 million years ago,large reptiles roamed our planet.An asteroid wiped them out within a few months.The fact is that this planet has been destroyed by internal as well as external forces many...

I didn't know that about the stuff being toxic to dogs.That rules out that idea.Don't want to kill my little buddy.

The reason I brought this up is,I worked at a cheese plant where we had a 300 gallon tank of propylene glycol,cooled to -40f.It was pumped to 2 heat exchangers that cooled the cheese.The glycol...

Great minds think alike.LOL.
I bought a submersable pump,clear hose,and all the fittings from Home Depot.Got a nice rectangular box at work.We receive small parts from a vendor in these.The hard...

You aren't missing anything.The most expensive part is the pump.I saw one in a catalog for $150 without the pump.Just a plastic box with a metal top.That is obscene.

Just wondering if I could use propylene glycol,(non toxic ant-freeze)as a coolant for machining and grinding.At one time I could buy water soluble oil locally.I really liked it.It never discolored or...

If I understand correctly,you are using a drill chuck to hold the end mill?If so,it doesn't matter how much you tighten the chuck.The end mill will work it's way out.You should be using the proper...

I have converted 1 phase,2 pole single phase motrs to 3 phase for building phase converter.The reason I did this is that the 1 phase motor has a governor/start switch that I used through a heavy DPDT...

As Verfur said,transformer welders do have advantages.They certainly don't walk away.LOL.I use one at work because they don't have an inverter.I get good results with it.No complaints.I don't know...

I used to sharpen all my drill bits by hand but,now I only hand sharpen the bits that are too large to sharpen in the Darex M-5 that was given to me.It sat for 5 years,brand new,barely used.I...

Aren't the inverters great? Too bad the local welding suppliers are still living in the transformer age.I have to order cerriated tungstens online.I find them far superior to the thorriated tungstens...

Greetings Drassk.
In my personnal opinion,you are much better off using proven techniques.If that stuff is as good as they claim,welder manufacturers would be looking for a new product to produce....

Oh yes.....thats what I needed to know.Thanks much

Thanks for the links CKM.I will order a copy today.As I understand solution heat treatment of aluminum,it is done in a brine solution close to the melting point of the alloy.Metals in the alloy like...

I would also like information on treatment processes of aluminum alloys.I have searched the net extensively without sucess.Machinery's handbook gives a description but,no details.If you find this...

More interesting reading.
Metal casting. appropriate technology in the small foundry,by Steve Hurst.My girlfriend gave this book to me for christmas.It covers casting techniques from around the...

You don't need to buy a crucible for Aluminum.I,and most everyone else uses a crucible made of steel pipe for melting aluminum.Brass is another story.I use a silicon carbide crucible for red metals....

I agree with Kipper on the books by C.W.Ammen.I have 4.Casting Aluminum,Casting Brass,The Complete Handbook of Sand Casting,and Constructing and using wood patterns.All very good books.He does focus...

A pig with lipstick.Never heard that one before.Good one.One the other hand....some of my former girlfriends bear a strong resemblence.

Thanks for the input.I was leaning toward the Newall C-80.Have you had any problems with yours?
Doesn't look like Mitutoyo is making DRO's like they used to.I also read on one of the dealer web...

Thats right,windows Vista takes up more hardrive space than the total capacity of most hardrives a few years ago.I bought a new HP laptop about 6 months ago.I tried to keep an open mind and I have...

I bought a Mitutoyo KC counter and glass scales for my mill over 10 years ago.They have worked flawlessly.Now I wish to buy a DRO for my 13X40 lathe.Just wondering what others are using and whether...

My thoughts are.....if it is dripping,it will stop.If it is spirting....Damn...got to stop working and go get some stitches.By the way,electrical tape can keep the blood off the machine until the...

Older than dirt but,still get around a lot better than a lot of people half my age.Honestly,if things get bad,I really don't think a lot of them will make it.

I use a natural gas fired furnace with a blower.The blower is housed in a separate console.The noise is not excessive....or maybe I don't hear as well as I used to.

I have been using steel crucibles for aluminum for over 2 years now.Doesn't seem to cause any problems.While the crucible is red hot,scrape the sides and bottom.Works well for me.I have not used any...

When I jewel a rifle bolt,I use a 1/4" stainless steel cup brush from dremel.Slide a couple of o-rings over the bristles.This allows the bristles to follow the contour of the part and return to the...

I would like to offer the best advice you will receive.You need to talk to Paul Barnett at South Bend Replicas in South Bend Indiana.His phone # is,(574)289-4500.He is probably the leading authority...

I used to use the insert type cutoff blades (Iscar) but,now I just use the parallel T-shape blades.Slow speeds and plenty of coolant and I am able to cleanly cut off about anything from mild steel to...

Your very welcome Joe.I have not tried any of the chrome kits.I think they are getting away from real chrome in favor of their "copy chrome",which is actually cobalt.Real chrome involves some really...
