The only problem that I have with ) scale Kadee's is that steel truck axles are attracted to the magnets--other than that, I don't have a Kadee magnet anywhere on the layout--homemade electric, and commercial magnets all.

Two things are important. As I mentioned before the magnetic poles MUST be crosswise to the track, and the pole ends of the magnets should be slightly farther apart than the ''air hoses'' when they are spread in the uncoupling position--and the magnet poles should be centered over the average coupler pair--slightly to the outside rail on a curve.

One of these days I'm going to have to run off a bunch of stainless axles, and have a glorious truck rebuilding session

Hi Herb

Thanks for the magnetic mystery tour !

As a big DIYer, I must say giving Kadee $$$$$$$$ for magnets...

...when I could just raid the fridge HURTS !

Not enough patience obviously !

If it's possible to explore outer-space...

...DIY Kadee magnets MUST be doable.

Cheers.

Si.

P.S. Herb, my all time favorite Kadee in ANY scale...

...is the metal option O-scale one...

...it looks right (when you polish the knuckle), it feels right (nice weight), & just operates ACE !!!

But you already know that, right !

(could be good for 1:35)

Thanks Herb, another expert lesson !.

I have indeed arranged the pole faces across the tracks BUT with the paired magnet pole ends touching rather than leaving an air gap between them.

OK Houston, back to the test rig track.

Hi Michael.

Just saw this for UK buyers, who might have heard of CPC.CO.UK

' Microfine Graphite Powder ' 50 grams.

CPC order# ... SA02595

2.97 quid + VAT

Page 2449 in paper-BIG BOOK

Might be good for all sorts of things, as well as couplers !

Cheers.

Si.

I used graphite powder on my Kadees after smoothing the parting line in the shanks. The difference was enormous. They coupled almost by touching the cars with a feather!. Jose.

Hi Salada,
if you are using non-Kaydee magnets for uncouplers the problem may be which way the magnetic fields are pointing for you magnets as described by Herb above - Yes that are directional and the Kaydee magnets are set up with a "offset magnetic poles that are specifically designed to pull the "air hoses" sideways.

What type of magnets are you using? Are they the more powerful rare-earth shiny ones or the way-less powerful grey ferrite ones? I have seen articles where they have used 3mm diameter rare earth magnets successfully.

As for using buckeye couplers in preservation service may I point you to my 2'gauge museum railway? check out the rear of Car 430.

These are 1/2 size standard gauge ones.

Buckeye coupler progress. Goodbye to 'Mr Bachmann's stuff !!.

I have now purchased a bulk pack of Kadee No. 148's on behalf of the D&RGW. Also a few Kadee 803's to allow the K 27's to (hopefully) couple up to Bachmann cars.

Si :

According to a review I have read the San Juan Car Co couplers only work on straight track so of no use in my "compact" track plan ! And so no 'magic wand' required.

Jose :

Could you please explain a bit more "..smoothing the parting line in the shanks". I have not yet examined or fitted any of the Kadees.

John :

I have been using grey ferrite looking magnets but rather stronger than the older type ferrites (a newer type iron alloy perhaps). I understand your comments re: magnetic polarity. To allow a fair test of magnetic strength I have also bought 1 Kadee magnet (Yes Si, rather expensive !) for trial use.

Your Car No. 430 looks very pretty. Was it regauged to run at your Museum or is/was 2'. 0" a normal tram gauge in Australia ?.

Also, I see the ends of your guard rails & wingrails are painted white, which I have seen in various other countries but hardly ever in the UK. I presume it is to prevent PW staff tripping over them ?  But you never see the switch toes white painted. ??.

My thanks to Si, Herb, Jose & John for your helpful replies,

Regards                    Michael

Michael:
Kadee shanks are cast in a two-part mold. Most likely there will be a parting line. File it down (inside also) with horizontal strokes (parallel to the ground) then sand with 600 or higher and finally burnish with graphite. Check attached pic. Jose.
