The first thing you need to do to use an easy-out is to drill a hole in
the broken stud. Since it is in a blind hole, the torque of the drill
motor will tend to tighten the stud into the hole. This is not to your
advantage. The solution is to go to the nearest serious tool store and
buy some left-handed twist drills. You can then drill the holes with your
drill motor in reverse. Often the vibration and torque will actually
loosen and remove the broken stud. At least it won't get any tighter.
If you have reason to believe that LockTite was used on the stud, a bit of
heat will also help, but don't go to hell with the gag.
Use the largest easy-out you can. The worst thing is to break the
easy-out off in the hole. They are very hard, thus prone to fracturing
and difficult to drill. Sometimes you can break them into smaller pieces
that will fall out. I usually drill the broken bolt/stud as large as
possible. I take it easy if the bolt resists the easy-out's efforts. If
it won't come with the easy-out, drill it out larger and put in a
high-strength threaded insert.
Another method used in shops is to call an EDM guy to come in, especially
for broken taps and such on expensive parts and immobile machines. The
EDM machine can "burn" out the stud (with or without broken easy-out) to
the minor diameter of the threads. The remaining spiral of metal can be
yanked out.
Be sure to wear your safety glasses when you do this stuff. Drills and
easy-outs are very hard, and pieces can fly when they break.

Subject: Re: SU Carb Sizes
>From my own archives...
-SU carbs are specified by throat diameter. Model (H, HD, HS, HIF, etc),
followed by the number of 1/8 inches bigger than 1".
fer instance:
H = 1"
HS2 = 1 1/4"
HS4 = 1 1/2"
HS6 = 1 3/4
HS8 = 2"
The carbs are sized for the flow requirements of the engine- while you can
put a bigger carb on a small engine, this should go along with improved
flow through the whole system- Bigger manifold, exhaust, and head porting,
and maybe valves. Of course, at that point you'll want to swap in a
hot cam shaft...
-Some other differences include:
fuel jet size
fuel metering needle profile
spring rate of the damper spring
mounting angle of the float bowl
vacum port fittings and their function
-if you get carbs off a different type of car, (even the same type of carb
and engine!), the needles are most likley wrong. If it's the same type of
carb, you can usually just get the proper spec needles for your car, or
look up similar engines in the needle spec charts to pick a starting
point.
This would be a good time to remind people of Dean Deeds "Haystack", an
SU Needle profile search and comparison program for the PC available from
the SOL file servers. (And, no- Bruce Carter never finished an
integreated, multi-platform version. I wouldn't mind a Windows version,
with Object links to Excel for graphing needle profiles and
differences...)
As we've said before, the main thing to remember here, is that all of
these parts form a SYSTEM, and if you want to successfully change one part
in the system, you usually have to change parts of the whole system. Just
changing one part can make the whole system work worse!

Subject: SOL Fileserver
Files on the British-cars file servers and how to get them: Rev. 11/4/93 RG
This file is posted to the list Lucas fashion- randomly.
The file servers are machines where various archives and articles of
interest are stored. You may get copies via "anonymous FTP", or by E-mail.
-----
A) FTP
If your machine has an internet connection, and runs the file transfer
program FTP, you've got what you need. Read your local manual/help on
using FTP.
1) Run FTP on your local machine, opening a connection to
hoosier.cs.utah.edu (155.99.208.5)
2) Logon as user "anonymous", and use your name as the password.
3) Change to directory /pub/sol. (cd /pub/sol)
4) You may list the files using FTP's dir or ls commands to see files.
5) Set the file type to binary using the binary or image command if
you're going to get something other than plain text files.
(Like GIF's, or programs)
6) Use get or mget to one or multiple files.
7) Exit with the bye or quit command when done.
-----
B) E-Mail server
Can't run FTP? If you can send and receive mail, you may also retreive
archives via an E-Mail server run by TJ Higgins. There are many more
seperate
articles in the misc directory of this server thanon hoosier.
To get instructions, send E-mail to:
ARPA'ish: server@ingr.com
or
UUCP'ish: ...!uunet!ingr!server
with the /HELP in the body of the message. The server will then send you the
help file with further instructions. (To your From: or Reply-To: address).
The SOL files are in the drectory pub2/sol/misc, pub2/sol/pic, and
pub2/sol/digest.
-----
C) WAIS
Hoosier is running an experimental WAIS server. (hoosier.cs.utah.edu,
155.99.208.5 port 210 Databases- sol and autocross). This is a networked
database index/search/retreive system. You can access this if you
have a WAIS client on your local machine.
-----
D) WWW
There is an expermental WWW (World Wide Web) link to the anonymous FTP
archives on hoosier.cs.utah.edu. You can get to this at:
old <A HREF=http://infotech.indiana.edu:80/will/b-cars.html>
new <A HREF=http://www.law.indiana.edu:80/misc/b-cars.html>
If you aren't familiar with WWW, it is pretty darn keen. There is
a windows client called Cello and available from
fatty.law.cornell.edu in /pub/LII/Cello.
If you have X you can use XMosaic. It is available from ftp.ncsa.

And, in the same magazine (or was it Vintage Motorsport?) look at the B&W
photos from Mosport. First, there's a picture of Steve Morrison's Ginetta
G15 (car I've been crewing for) behind something. Turn the page, and
there's a picture of my new Bugeye, #111 alongside some Alfa's, being
driven by the previous owner.
