This close helm is  patterned after one dated c.1510 in "European Weapons and Armour" by Ewart Oakeshott on Plate 7 item C.  The bar grill visor that is closely patterned after a late 16th century style tournament visor.  It is all  304 Stainless Steel, (12 ga top and rondel,) 14ga. visor, bevor, and back, and 16 ga. gorget. The weight is about 11 pounds. It has dual spring pins to keep visor closed.
        The pattern is sized for someone with a head that is 24 inches around at forehead level and 10 inches from the top of their head to the top of their shoulders.

Notes about Patterns:        All of the patterns by Craig Nadler on this web site are on 8.5 inch by 11 inch graph paper. The large squares on the paper are 1 inch by 1 inch. If you print the patterns as 8.5 inches by 11 inches with no margins they will be full scale. Instructions on how to do this are at the bottom of this page. If the patterns don't give a size they are men's size medium.        This pattern is copyrighted, but this is only to stop someone from publishing it without giving me credit. Feel free to use any of my patterns on this site to make armour for personal use or for sale.       -Craig Nadler Armour Projects by Craig Nadler

I would build this helm in the following order:

1)   Cut out the plates.
2)   Finish the plate edges and corners.
3)   Punch/Drill the two pivot holes in the bevor and the tops of the visors where they are marked on the patterns.
3)   Role the edges on the two bottom neck lames.
4)   Dish and shape the top halves.
5)   Weld the top halves together.
6)   Shape the back plates and weld them onto the back the helm's top (also weld them together) .
7)   Grind welds flush on the outside and cleanup weld on the inside if needed.
8)   Put a medium (around a 220 grit) finish on the helm.
9)   Shape the bevor and fit it to the helm.
10) Shape the plates for the sparrows beak visor and fit them together.
11) Weld the plates for the sparrows beak visor together.
12) Grind welds flush on the outside and cleanup welds on the inside if needed.
13) Put a medium (around a 220 grit) finish on the sparrows beak visor.
14) Fit the visor and the bevor to the helm and mark where you want the two pivot points.
15) Drill/Punch 1/4" holes for the two pivots.
16) Use 1/4" rivets for the pivots. I drill 3/32" holes near the end of the rivet shafts for cotter pins. This way I can remove the rivets and change the visors. Be sure that the length of the rivets aren't excessive.
17) Shape the plates for the bar grill visor and fit them to the helm.
18) Weld the plates together for the bar grill visor.
19) Grind welds flush on the outside and cleanup welds on the inside if needed.
20) Put a medium (around a 220 grit) finish on the bar grill visor (frame).
21) Fit the visor to the helm again and adjust as needed.
22) Shape the bars and rivet them in place. I use 5/32" rivets for this.
23) Drill/Punch a 3/8" hole in the tail plate on the back of the helm where you want to attach the post and rondel.
(24-31 This is how I make the post and rondel)
24) Grind and/or sand the head of a 3/8" partly threaded hex bolt so that it is a semi round head. The part of the shaft of the bolt that is seen
on the outside of the helm should be unthreaded.
25) Cut a 3" diameter disc out and finish the edge.
26) Drill/Punch a 3/8" hole in the middle of the disc.
27) Put the bolt through the hole in the disc so that the disc is against the head of the bolt and weld the disc onto the shaft of the bolt.
28) Weld a washer onto the bolt just above where the threading ends.
29) Clean up the welds on the post and rondel (bolt and disc) as needed.
30)  Put the threaded end of the bolt through the hole on the tail on the helm and use a nut to attach it.
31)  Be sure to cut off  any excess on the bolt shaft that extends pass the nut. Finish the end of the bolt so that it isn't sharp. If you plan on
using the helm with the post and rondel  you will want to get or make a low profile nut so it does hit you in the back of the neck.
32) Put each visor on the helm and mark a line on the top of the helm where the top edge of the visors are near the center. If one visor comes up higher in the center then the other you will need to cut and/or grind it down until they both line up the same.
33) Drill holes for spring pins on each side of the comb/crest where the lines for the top edge of the visor are.
34) Attach spring pins and adjust the holes for the pins as needed.
35) Polish the helm and neck lames.
36) Attach the neck lames.

How to print the patterns: From Redhat Linux 5.1 with xv (Should work on any Linux or UNIX with "xv"):     Load the JPEG pattern files into "xv" (example "xv elbow_p1.jpg"). Print the file from "xv" as a grayscale image on a 8.5" X 11" page with the height and width set to 102.50%.  Remember to "Center" the image after setting the height and width set to 102.50%. From MS-Windows 95 :     If you run the program "Imaging" that's under the "Accessories" menu you can load the JPEG pattern files (*.jpg) and save them as MS-Windows Bitmap files (*.bmp). After that load the Bitmap files into "Paint" (which is also under the "Accessories" menu). Then stretch the image 128% both horizontally and vertically. I set all the margins to 0.25 inches, which was as small as the printer driver would allow. It this point I was able to print the pattern so that the squares were 1 inch by 1 inch as they should be.
