Irish Railway Models A Class Re-wheeled to 21mm
JohnMcGahern replied to JohnMcGahern's topic in Irish Models
Hi Christian, It's been a while since I purchased any wheels from this guy who I believe is in England but gets these wheels that are manufactured in Australia. http://branchlines.blogspot.com/2006/07/black-beetle-nickel-silver-wheels.html I can't seem to find any contact information on this link but these are the wheels I've used with all my locos. I had used Ultrascale once, but they don't come in an all metal back so it is a pain to try and get the pick ups to make constant connectivity. With the all metal backs it's easy. You need the fully insulated ones which I believe are a special order. The down side to them is the hub area I find is not manufactured as well as the Ultrascale ones and as a result are not as easy to get squared to the axel. Ultrascale ones are better made and have a larger (deeper) hub and are so much easier to square. If they came in an all metal back I would go for them all he time as a wobbly wheel )although functional) is annoying as hell! -
No problem, thanks for the reply!

Love the tall grass on some of these photos. How did you do it? Is it static grass?

When I initially started the layout about 7 years ago (hadn't touched it for the past 4 years) I hadn't even heard of the under track magnets otherwise for sure I would have gone that route. Although, there would have to be considerable planning made ahead of time for cutting out the baseboard (unless someone here has another way - I'm all ears) I know what you mean though, they are an eyesore but those magnets are only temporary and held in place with believe it or not, blue tack! To be honest I'll probably never stick them down permanently in case I ever want or need to work on that area of track and it actually works well as you can easily adjust them to the right height. I've even tried the small neodymium magnets between the sleepers but never had any luck.

Thanks popeye! I know, neither of them have moved a muscle all f***in' day! Ha! Thanks Patrick!

Amazing detail! -
Photos of re-wheeled 121 and A Class to 21mm plus shunting video
JohnMcGahern replied to JohnMcGahern's topic in Irish Models
Thanks for the compliments guys! It's amazing how a camera can create the illusion of expanse since the whole thing is only 6' x 2.5' -

I've had great success with all of them. I always try to go with the smallest I kind before getting buffer lock on smaller radius turns.

Awesome work Brendan. It actually reminds me of a technique used by a company here in North America called Fast Tracks. I had tried their 00 point work years ago and loved the smoothness of the crossover with no "drop" as the vee and adjacent rails were a lot closer together than a standard Peco point. I still have their point jig which is made out of some sort of metal which you would solder the sleepers to the rails in. I'll throw in a pic so you can see it. Anyway I had actually contacted the company years ago and inquired about a custom point jig in 21mm - needless to say the price was ridiculous so I decline and that's how I got started in P4. Actually I still have a bag of copper clad sleepers which I use for my 'tiebars" on the points. A complete fluke as they fit under the bullhead rail and slide back and forth with just enough resistance to keep the point rails tight against the stock rails. I solder the point rails to the copper clad tiebar. I then use a push rod from underneath the layout to switch the points as well as an electrical switch to change the polarity. -

Thanks! Yeah, I only just installed the wheels and still trying to correct a couple of wobbly ones so once I'm happy with it I'll spray paint then. Thanks for the compliment, always great to get feedback positive or negative as we sometimes wonder what kind of a job we're doing. So what kind of spacing do you have at your crossings? It must be like 00 right? If that's the case I almost wish I'd have known that years ago as it would be a lot less hassle! -

Irish Railway Models A Class Re-wheeled to 21mm
JohnMcGahern replied to JohnMcGahern's topic in Irish Models
Thank you sir! Yes it does, especially for the Irish models with the difference between 16.5mm and 21mm. At 4.5mm that's 13.46 inches in real life! If I was modelling English stock I don't think I'd bother with only 2.33mm difference but this is almost twice the difference. -

Furthermore to an example of my not so fussy P4 ways...If you look at the beginning of the video you can see one of my rail joints. I'm using a standard Peco joiner as opposed to having nothing but the P4 soldered scale fishplate. I do like to use those wherever I can, but that depends on the accuracy and flushness of the two adjoining rails. If the two rails aren't sitting flush for whatever reason then I simply use a Peco rail joiner which would make for a nice flush connection and thus smoother running of rolling stock. Honestly speaking at my age and deteriorating vision, the scale fishplates are only there for the benefit of better photos. -

Regarding the P4 profiled wheels yes, as any standard 00 will not fit through the crossings. As far rolling stock is concerned. Since my layout is a 6 x 2.5 shunting yard there no coaches, just wagons. Compensation: Ironically, I found that the wagons I did compensate derail more than the ones that I didn't. Having examined the bottom of the compensation I have since realized that I didn't aline the two sets of wheels perfectly, and I believe this is the problem. With the uncompensated ones, it's just a simple case of gluing the sole bars to the body approximately 1.5 - 2mm out from center. FOr some strange reason they work perfectly fine. So in future I won't be bothering with that extra step. Based on that I strongly believe that the most important factor is as close to perfectly laid track as possible. ie; joints should be as flush as possible and the overall track as flat as possible. I don't build in situ but construct each piece on a piece of glass (can't get any flatter than that) over Templot templates, test run them on the glass with a loco/wagon then transfer them afterwards. I dod "cheat" with the crossings however (purchased from C+L Finescale) as I found trying to construct my own far too frustrating. Everyone has a different level of patience I suppose. I found the best route was to buy some Parkside Dundas kits as I found trying to manipulate a standard Hornby or Bachman model was too difficult. Just to add, I'm not so much a P4 stickler that I have to have everything perfect and the odd elitist may not approve of my methods but I care more about making it work mechanically well rather than going against the "allowable tolerances". Example: You may have noticed a wobble on my A Class video, yes that bothers me and I will try to fix it, but other stuff I can live with. II'll take some more pictures/videos when I get the chance. -

JohnMcGahern replied to JohnMcGahern's topic in Irish Models
Yes, I replaced with P4 wheels as the profile (flanges and tyre width) are too big to fit through the point crossings, so if you have P4 track then you won't be able to keep the original wheels. Hmm, now there's something worth trying. The problem is getting them to sit perfectly without any wobble. Like I said before though, as I forget they're even rotating half the time, I'm not sure I'd be willing to put in the effort. In fact, the only time I've looked at the rotation recently on the A Class recently was watching the video I made
