Our scheduled speaker was unable to be with us tonight but is expected to be at the June meeting. Member Frank Dorion filled in with a very interesting talk on spring making. I video taped the presentation and it looked OK on the camera monitor but came out very dark on the computer. Still it is better than nothing so I hope that you are able to get some useful information out of the tapes. I have broken up the talk into six minute segments to keep download times within reason. Since the film quality is so low I have posted the clips in WMV format since that format loads faster and the lower quality is not so important here.
I will be visiting Frank's shop in the next week or so to photograph the tools he was showing and passing around during the talk so check back to see those photos. I am sure that they will make the talk more informative.

UPDATE 26 May 2009
I was able to visit Frank's shop and take some photo and video which should add greatly to his talk.

Above: A variety of tools used in the spring making process. L to R are winders, various cutters, mandrels, a sample of wire used in making springs and a specialty pliers used for making the end loop on extension springs.
An excellent site for information about making springs is: http://home.earthlink.net/~bazillion/intro.html
Another style of spring maker. The wire is fed down between the rollers and forms the coil against a stop. This style machine can be seen in the opening part of the Watch it Made or How it's Made TV show.
The di-acro spring winder that Frank demonstrated during his talk. He plans to draw up sketches which will enable one to make a similar machine.
Torsion springs Frank is making for a fellow who is rebuilding a machine. The center photo is of a pile of "practice pieces". In the right photo note the two rusty looking springs. These are originals and are being used to guide the process. Note too that there are left hand and right hand springs to be made. Note also the small "kick up" on the short end of the spring. The di-acro bender in the photos below will be used to make that detail.
Here are some photos from the meeting.
