Clint Not much as far as I can tell. It looks like they need some casting input :-) Mikey Just a post to help keep the group active, amnyone doing anything? ...
I'm very new to the list, but I must congratulate you all on the tremendous amount of work you've done so far bringing the Metalmaster out of obscurity. Great...
Bobby I'm new to the group too, and am also a writer ("Gas Burners for Forges, Furnaces, & Kilns" Skipjack Press 2004). You have put your finger on the two key...
... Hey, small world! I bought your book just last month. ... A design derived from the original could be published without copyright issues, as long as...
Hi, Robert. The only CAD drawings of which I am aware are some that I made from Mr Urwick's original drawings. These are definitely NOT cleanroom drawings. I...
Bobby No question in my mind that cast iron is the way to go for the Metalmaster castings; its rigidity will be very important. Mikey ... From: Robert Nansel ...
Hi, Mike. (Sneaky, masquerading as Kathy, but I'm on to your tricks!) I'm thinking that one of the ZA alloys (and I'm inclined toward ZA12 for various...
How about Aluminum castings filled with cement (or ?)? Ship them unfilled, lower costs to make and ship, and let end users fill them locally with their own...
... A polymer concrete mix can work, but normal concrete isn't stable enough for precision machinery -- concrete can continue to change dimensions for years. ...
... If I were to make a set of patterns, I would make these for ZA, as this is the easiest to cast under my conditions. Sure, CI would be best, but ZA has...
No fooling. One of the reasons I did the CAD work was to work out some of the processes required to make one of these wee beasties. I must admit to getting...
It's hard to say how large a market there might be for the sort of book I'm proposing, but I figure the popularity of the Gingery machine shop books must mean...
... However, a new design derived from your CAD drawings would, for copyright purposes, be a cleanroom design, especially with the kinds of modifications I'm...
Hello Bobby, I like this idea. I am willing to help if there is something I could do. My field is electronics. I an a hobbyist when it comes to machining and...
Bobby, Here you are talking more of what I like; fewer complex castings, etc. I have other small machines which I could use to do most of the steel plate ...
My thoughts. 1) CNC at least as a forethough sounds great. Especially as it would cut down on gears etc. 2) For copyright, credit where credit due and moral...
... Yes, I agree, lost foam and other investment casting techniques are something to look into, particularly if we could devise a simple way to produce the...
Donald It used to be Kathy's URL, but the computer is now mine; she works on a laptop these days. Kathy's name shouldn't have appeared though. We were trying...
Personally I love bootstrapping, but there comes a time when you must consider your likely audience; it isn't going to be people without the present ability to...
... hadn't heard that it was considered as rigid at all. Gene in Gig Harbor has cast a large pipe wrench in ZA12. I'm not sure he is a member here though (I...
Bobby Have you got the link to that website? ZA-12 is pretty close to Cast Iron as far as strength and other properties for those that cant do cast Iron, I am...
IMO, comcast email is OK. It's Windoze that sucks. :) I suspect your MUA (mail user agent) has Kathy's name associated with this account. I see you are...
Tell that to J.K. Rowling, and watch her spit. She was sued over a mere idea--nothing more than a vague resemblance to the idea at that. Cost her millions to...
It seems I've created some raised eyebrows with some of my statements about copyrights, clean rooms, etc. Let me start over ... Hi, my name is Bobby Nansel....
