For the last couple of weeks the way my forum pages have been displayed has changed, There are no graphics, none at the top, no emoticons, even the little "new post" icons are gone. all of this has been replaced with text. Has something changed. I haven't made any changes to my computer, that I...

Has anyone had any experience using auto body spot glaze or body filler on brass. Does it stick well or is there a tendency for it to peel off. Thin coat application.

My old vise was a complete basket case from day one, 15 thou out in one direction 5 thou in the other. Well I finally got tired of it and started looking fot a new one. Kurt's, still laughing at the prices, Glacern, well I was going to go that route but I was at Cabin Fever on the weekend and...

Many years ago I built the "Schreckling FD3 64" miniature gas turbine, this picture is of not mine but is the same design and in it there was a shrouded centripetal compressor impeller that was made out of R/C aircraft grade plywood reinforced with carbon fiber "twine" and crazy glue. It was not...

Lots of info here http://icrank.com/cgi-bin/pageman/pageout.cgi?path=/index_html.html

Some time ago I found (and lost) a site on the web that showed how to manually machine a centrifugal compressor impeller of a type that would be used on a small home built gas turbine engine. Does any one no where that kind on info can be had. Info on casting one would be equally useful. Thanks.

I am in the middle of turning a #5 Morse taper sleeve out of 416 SS, using the tailstock offset method, and when I started I had some bad chatter. After playing with the speed it settled down to a nice chatter free matte finish. After a couple of passes the chatter started up again but as I got...

Some time ago I bought one of those 4 x 6 angle tables that are everywhere now and they are OK but have one annoying problem, when the table is tilted over near 45 deg. it is almost impossible to tighten down the bolts that hold the table angle without interfering with the bolts that hold it to...

I have a RF45 type mill (square column with dovetail) and I would like to put a head raising motor on it so I can bore holes under power, for a better finish. Most of the one I have seen with this feature have the motor built into the top of the column connected to the drive screw that does...

Found this forum on sheet metal work that has a good library of old books on the subject. Model makers may have to be able to bend metal so maybe these will help. Look in the library section http://www.thesheetmetalshop.com/

I found these videos on Youtube, 25, all by the same man, on making Live steam loco's and similar topics. They are about 5 min. each, usual Utube quality but interesting. http://www.youtube.com/profile?user=trainman4602&view=videos

Found this web site that has old and new books and magazines on line for reading. Under the craft section there is some stuff on model making and machining, a lot of this is probably the same as what is available for downloading off of the Internet archive but there is some new stuff to. You...

Yesterday I was boring out a piece of 3/4" thick aluminum plate, 3" ID, grade unknown, and when I was about .050" under size I made a couple of cuts with out moving the cross slide to turn the "spring out" so I could get an accurate measurement before making my final assault on the finish dia...

I was cruzin' the net and found this site from the "Fox Valley Tech college", if it's been posted before then just ignore it. It has its machine shop training on-line for those like me (newbies and "to olds ta learn") that are always in need of info. If you look through it there is quite a bit...

This might be in the wrong category but it looks like a nice idea for a small engine. Someone asked a question in a 1936 Model Engineer mag about this type of engine and while not practical for power generation it might make a good conversation starter. It's sound powered. A rod is connected...

I have to build a rifling machine to rifle the barrel of my 1/6 scale WW1 18 PDR. artillery piece model. It is non-firing so the rifling doesn't have to be as good as a real firearm but I want it to look proper. The barrel will be 16" long, .55" cal. with 17 grooves .004" deep I have had a rack...

What do you consider to be an acceptable level of accuracy for model making? I have always strived for .001" as a standard where it counts, some times I make and ...... In the golden olden days of Model Engineering when the main measuring tool was a ruler marked out to 128 Th's and parts where...

I'm familiar with M 2 and M 42 grade of endmills but I just found a catalog with an M 57 grade roughing endmill, it contains aluminum instead of cobalt, its suppose to reduce friction while milling. Can anyone enlighten me about this grade of material and what they are used for.

I have been thinking about picking up one of the 5C Spin indexer's with a set of collets for simple indexing on the mill, has anyone used one of these and are they useful enough to make the price worth it. Currently I use an 8" H/V rotary table (heavy too) with a chuck on it but this requires a...

I have been building a 1/6 scale model of a WW1 18 PDR artillery piece (single cylinder,single stroke engine with a disposable piston) and for the last five or six years have been looking for a full sized example to take detailed photos of, without any luck. There are few examples left here in...
