Re: Poor Man's DRO

A friend of mine put a poor man's DRO on his tailstock ram. He used a 6" digital caliper, the kind that Harbor Freight now has on special for $19.95. It works great! I have half a notion to do the same; and, to put one on the quill of my drill press.

Need gasket removal hints

My Quincy compressor blew a head gasket and I'm looking for hints on how to remove the old one from the aluminum head and valve plate without damaging the soft base metal.

Re: Seeding the forum with casting Do's and Don't's

Iron contamination of aluminum is bad. The cast aluminum will have very poor physical properties. It other words, it will lack strength. Iron is very easily dissolved by molten aluminum. It only takes a tiny fraction of a percent of iron content to do its damage. If someone goes to all the trouble o...

Seeding the forum with casting Do's and Don't's

I can think of no better way to start out with a forum than to list some Do's and don't's. Here's my 2¢ (First, don't try to use the Tab key when insetting.) 1) Do use protective apparel: Full face shield, boots, apron, long sleeves, leather gloves and respirators, when appropriate. 2) Don't use iro...
