Started the change over to Kadees last weekend. Have a few cars done already. I bought a package of shims from Micro Mark which have made the conversions much easier but I am going through shims at an alarming rate. I worked on a Weaver boxcar last night and it took 4 of the thickest shims for each coupler. I know I can buy styrene which I will probably wind up doing. Have any of you used this much material to shim your kadees? How much leeway do you allow in coupler height? I bought the coupler height gauge Kadee makes and I try to be dead on accurate but honestly even the car which took 4 shims at each coupler might have taken one more thin shim. Is there an acceptable amount of height you can be off when using the gauge?  thanks for your help.  Gerry

Yes    That explains it ! take the whole coupler off. I use plastic sheets from the hobby shops for shim stock, actually anything will work. blister pack plastic, card stock, playing cards, the nice post cards. I cut the holes with a punch I got at hobby lobby they come in different sizes. Have fun

Thanks for your help. I find if the whole coupler arm is removed the wheels will rub on the bottom of the car or sometimes on undercarriage detail. I have been using some small washers which make the height a bit less than if the whole arm is removed. Have you run into this?

Great ideas for shims!

Thanks again.

Gerry,

What has happened to you is pretty common with the Weaver cars when the coupler shank is removed. The cars sit high anyway and look better lowered but the drawback is the tall flanges of the wheels getting close too and sometimes rubbing on the underneath of the car body. Thin washers are a good fix. Stack them until the flanges will clear. Under body detail that is in the way can be trimmed away. I like to use a washer with the largest outside diameter and the smallest center hole I can find. I find the large diameter has a tendency to keep the car body from rocking.

I've run into a few issues with passenger cars and tenders that require a very thick shim. The above solution works well from Weaver. Cut off the truck mounting portion and drill out the coupler mounting holes and you are left with about a 1/8 shim. At about $8.00 a pair they are a bit more than making up your own. The Weaver couplers seem to work well. These I'm guessing were Weaver's answer to Atlas' adjustacoupler.
