KRM HO 40ft Ladder Stiles
Information Page


Price $6.70 (Aus$)

This page is dedicated to information that will assist the modeller in using the 40ft Ladder Stiles
As with all Photo Etched parts, be very careful when handling them, and always read through the instructions a few times before working with any new kit.

This kit has been designed to be constructed with the use of the KRM MISC 004 Ladder Forming Support Jig. The ladder can be constructed witout the jig, but the jig makes the job much easier.

Step 1 - Tools & Equipment
Tools & Equipment

If there is one thing that I would like to impress upon you, it is the benefit of using quality tools to do your work, The end result of any job is plainly due to the use of good quality tools. And there is also a saving by using good tools, because they last longer, and therefore you do not need to replace them as often.

  1. Stainless Steel Scissors
  2. Tweezers or other small no maring clamping device
  3. (Metric) Number Drills & Pin Vice
  4. Small Files
  5. Soldering Iron
  6. Hold & Fold Tool
  7. Solder & Flux or Solder Paint
  8. Snap-off Cutting Blade
  9. Fine Wet & Dry Paper
  10. 0.3mm brass wire (0.012")
  11. Burnishing Brush (Be very Careful)
  12. Selleys Acrylic Quickgrip
  13. Cutting Board
Lets get ready to Moddddddeeeeeelllllll
Step 2 - Preparing the Etch
Prepare the etch
  1. Re-Read the instructions (Yeah I Know!!!!!!)
  2. This kit supplies four (4) ladder stiles to construct 2 x 40ft HO ladders.
  3. PLEASE NOTE - because of the limitations in the etching process, some of the rung holes may have flash in them, or may not be etched through completely. This may require them to be drilled through.
  4. Using a 0.3mm drill, clean out the holes in the ladder stiles. You may choose to use 0.4mm wire rather than 0.3mm, if this is the case, you will need to drill out the holes in the stiles to suit.
  5. The ladder stiles can be cut to suit the ladder length required, and formed in the ladder support forming jig.
  6. The ladder construction is much easier when using the KRM MISC 004 Ladder Forming Support Jig
Step 3 - The ladder>

  1. Place the ladder stiles in the jig in the appropriate slots, depending on your ladder width (Refer to top photo at left)
  2. Locate a piece of 0.3mm brass wire (with overhang) into the top and bottom rung holes of the stiles and drag the stiles and rungs down so that the rung hits the vertical sections of the jig. This squares the stiles to the jig. (Refer to 2nd photo at left).
  3. Place 0.3mm wire into the ladder rungs and solder into place (do one side first). I prefer to use Carr's 188 solder paint. Simply place a dab of paint on the end of the rungs and heat with the soldering iron. The solder paint flows so that the joint forms through capillary action. (Refer to 3rd photo at left)
  4. Take the time to work your way down the ladder, leaving the rungs that are near the support brackets until later.
  5. Once all of the rungs are soldered in place move the ladder in the jig, so that you can solder the rungs into the remaining holes. (Refer to bottom photo at left)
  6. You need to be aware that the use of only enough solder paste is advised, to reduce the amount of clean up required.
Step 4 - The Clean Up
the clean up
  1. You need to be very careful with the clean up of the ladder, as it can be easily bent and twisted.
  2. Once, all of the rungs have been soldered into place, cut away any excess wire.
  3. Using a fine file, file away the excess solder on the outside of the stiles, and use fine wet and dry paper to finish the job.
  4. If you have use the solder paste sparingly, there should be a minimum amount of solder on the inside of the ladder stiles. Carefully clean up what solder has built up.
  5. When the ladder has been cleaned up, wash it in warm soapy water to remove any trace of the flux from the solder paint (as it can be corrosive). (Refer to photo at left)
  6. The alternative to the solder paste is a home made solder flux by a friend of mine, which is available by contacting Keiran Ryan Models by email or phone on 61 2 46772462
