Extended Knuckles for Kadee® #5 Head, McHenry™ HO Couplers, or Bachmann® E-Z Mate® Mark II HO Couplers



Introduction:

Extended knuckle coupler installed in link & pin draw head on the Robert Dollar shay, Roots of Motive Power, Willits, CA, 5/20/2005. Yes, the draw head IS mounted upside down; No, I don’t know why. It was that way in service.
A common complaint we hear from our customers is the fact that they have trouble finding cars whose coupler height matches very low coupler height of Bachmann’s On30 locomotives and freight cars. (It’s the Bachmann cars that are off, by the way. They’re set to NMRA HO standard gauge height, which quite low for O scale.) While this problem can be somewhat alleviated using couplers with offset heads, real railroads found a solution to this problem ages ago: extended knuckles. Oddly enough, there is no “standard” coupler height in prototype railroading in the United States. The F.R.A. rule-book only specifies that there has to be less than a 4″ mismatch in relative coupler height. Remember, prototype cars can have new/old wheels, different trucks, different draft gear, different couplers, and can be empty or fully loaded. All which effect where a coupler ends up relative to the top of the rails. Coupler mismatches were far more common before WWII on standard gauge railroads and was fairly common throughout the history of narrow gauge and industrial railroading; particularly in the logging industry.

The patterns for this part were made by Dave Squire, an accomplished pattern maker who has done work for PSC and The Back Shop. In fact, if you’ve been around narrow gauge modeling long enough, you probably own some of his excellent work already and don’t even know it! Foothill Model Works is proud to add this incredibly useful part to our line of detail parts. Orignially designed for the old, “whisker spring” McHenry
Installation Instructions:
While the prospect of disassembling and reassembling an HO coupler may seem daunting at first; in reality, it really isn’t as hard as it looks. All of these couplers operate in exactly the same way as Kadee
For Factory Draft Gear (Unmodified Shank):
- Remove the coiled spring from the side of the knuckle with a pair of tweezers and put it in a safe place.
-
Remove the iron trip pin wire. While this can be done with a pair of needle nose pliers, the easiest way is using a wheel puller.

Trip pin being removed using wheel puller. Be sure to fully support the head using a plate with a small hole in it. We used an old screw with the pin ground down to about the same diameter as the trip pin wire. -
Measure your trip pin wire and the drill pivot point hole one drill bit size larger. Kadee
® uses a 0.040″ iron wire trip pin, so use a #59 drill bit. McHenry™ uses a 0.039″ iron wire for a trip pin, so use a #60 drill bit. Bachmann® uses a 0.038″ iron wire for a trip pin, so use a #61 drill bit. Always double check your particular trip pin wire, or, if in doubt, start a couple sizes smaller and work your way up.
Drill pivot point hole here. -
Test fit knuckle in shank housing. The pivot portion of the knuckle should fit as cast, but might require thinning on some non-Kadee
® couplers. The best way to test fit the knuckle in place is to use a scrap piece of brass wire the same size as your trip pin wire to temporarily hold the knuckle in place. Using an unmodified coupler as a guide, check to make sure the knuckle closes all the way. The side of coupler shank housing may need to be shaved with a razor blade or the casting filed down to allow the knuckle to close all the way.
The edge(s) that will need to be modified so knuckle closes all the way. -
The iron wire trip pin you removed in Step 2 has two ears mashed out of its sides where it attaches to knuckle. These will need to be filed down until they are slightly fatter than the rest of the wire, but NOT down to the same size. These ears will be what holds the knuckle to the trip pin. Supporting the head of the coupler and using an unmodified coupler as a guide as the rotation of the trip pin relative to the knuckle, reinstall the knuckle and press trip pin back in place. You will be forcing the fat part of the trip pin into a hole that is too small for it, so some force will be required. Grip the trip pin just outside of the shank housing and press it in a little bit at a time. Never grab the free end of the trip pin and press from there. (You’ll bend the wire and send the coupler flying!)

Trip pin “ears” that will need filing.
Pliers being used to insert trip pin wire a little bit at a time. - Replace coiled spring with a pair of tweezers.
For Slotted, Link & Pin Draw Head (Modified Shank. Only Use with Centerset Shank Couplers.):
- Follow Steps 1-5 as above.
-
File or shave using a razor blade, the fillet in the inside corner, between the back of the head and the top of the shank square.

File this inside corner square. -
Drill a #77 hole through the shank, centered on the shank, up against the back of the head.

Drill here. - Measure the pin used in your slotted, link & pin draw head. Drill one drill bit size larger, through the detent cast into the slotted shank extension casting. Be careful to keep the drill bit square to the part.
- Remove the extension casting from the sprue and file the end to match the curve cast into it.
-
Press the extension into the hole drilled through the shank in Step 3. Using the same drill used in Step 4, drill through the center of the shank, through the hole drilled through the extension.

Drill like this. -
Trim the coupler shank to match the length and shaper of the extension casting.

Shank trimmed and rounded. - Replace coiled spring with a pair of tweezers.

MacLeod Western Truck Bearing Inserts

Introduction:
We have long been huge fans of MacLeod Western’s line of trucks and detail parts. Without them, we would be stuck in a world of really expensive, brass trucks and/or an unending supply of “yet another pair of Delrin
The quick and dirty fix: lubricating the journals. A good, plastic compatible oil can help, but the oil can effect the paint. Packing the journals with graphite works well too. Unfortunately, neither solution is permanent and will have to be redone from time to time.
The more permanent solution: a bearing insert. Those of you who remember Russ Simpon’s West Side Lumber Co. trucks (which were also styrene) will remember that he used half of a brass rivet as a bearing insert. This worked well, but still needed oil for the brass-on-brass wearing surface and finding a reliable supply in the days of Chinese manufacturing is, well, “problematic.” So, we decided to make our own bearing inserts cast out of the same long wearing, Celcon
The result: Beautifully free-rolling truck without squeaks or the need for oil!
A friendly word of warning: While modifying MacLeod Western’s trucks for these bearing inserts is not especially difficult, it does require some specialized tools and does have the risk of breaking the sideframes. Proceed at your own risk as
Tools Required:
-
A 7/64″ (0.1094″) Drill Bit. A good one (aka NOT from Wal•Mart or Harbor Freight). Unfortunately, most drill bits are made for drilling into steel or wood, and are, therefore, WAY too aggressive. The helical angles and rake angles are too high for plastic. In short, they
will snag in the first 1/4 turn and rip the sideframe apart. If you have a good 7/64″ drill bit that cuts a straight, true hole, you can grind the rake angle on the tip to a flat, 0°. So the tip will scrape, rather than cut like a chisel. I started off with a D-bit cutter I ground myself with the same rake angle. If your name isn't Scott Kitts, the simplest solution is to just buy a good straight-flute drill bit. McMaster-Carr has one for $11.19 (part No. 8944A14).
Standard twist drill with hand-ground, zero-degree rake angle (along edge indicated by arrow) for scraping. Courtesy a machinist friend.
Commercial, straight-flute drill bit.
Hand made, D-Bit drill bit. -
A Drill Press. One with a good chuck and that you can control the speed of. One of those contraptions that converts a Dremel Tool into a drill press would
NOT be a good idea here (its 5,000 to 35,000rpmsWILL turn your sideframe into a puddle of goo). You’re looking for around 200-300rpm. We use a Cameron Micro Drill Press Series 164 with a speed control (Variable Speed Control Model 2A), an Albrecht chuck (0-1/8″), and a dial indicator depth gauge (we used one from Harbor Freight). A small milling machine like a Sherline or a Unimat would also work. I can’t see a pin vise working well here. -
A Jig or Clamp. A jig can be something as simple as a plate with a hole in it. Basically, you’re looking to hold the sideframe flat, securely.

Random junk plate with holes in it as a jig. With “ultra-safe” finger clamp.
Sideframe held in Sherline vise. Sideframe may need to be shimmed to get secure hold.
