21mmp4 Posted September 22, 2014 Posted September 22, 2014 Nenagh is a 4mm layout based on the original track plan of this north county Tipperary town. The main track work for the scenic side of the layout is nearing completion and I hope to have a reasonable flow of photo's of the next number of weeks. More photo's in the Album. Quote
Dave Posted September 22, 2014 Posted September 22, 2014 Welcome to the forum! Lovely work so far. Quote
scahalane Posted September 22, 2014 Posted September 22, 2014 Very nice! the 21mm P4 really makes all the difference when it comes to looking like the real thing. I'm looking forward to see how it progresses. Quote
Junctionmad Posted September 23, 2014 Posted September 23, 2014 What are going to do for the non scenic track Beautiful track work btw Quote
Weshty Posted September 23, 2014 Posted September 23, 2014 21mm points. Hardcore stuff. Looks very well, keep us updated Quote
21mmp4 Posted September 23, 2014 Author Posted September 23, 2014 Hi Junctionmad, The non scenic track will be the same as the front, hand-built 21mm P4 on Ply Sleepers with C&L 4 Bolt chairs and 75BH NS Rail. No easy way out I'm afraid!! Quote
21mmp4 Posted September 23, 2014 Author Posted September 23, 2014 A few photo's of the track laying and ballasting on Nenagh. More pic's in the Album. Quote
RedRich Posted September 23, 2014 Posted September 23, 2014 It looks fantastic and right when you see the 071 posing on it. Could it be the first 071 to have been re gauged. I'm very interested to hear how you did it. Rich, Quote
Weshty Posted September 23, 2014 Posted September 23, 2014 How are you securing the chairs to the track, pins, glue etc.? Quote
Dave Posted September 23, 2014 Posted September 23, 2014 That looks fantastic, the 071 re-gauged looks so much better. What ballast are you using? Quote
Noel Posted September 23, 2014 Posted September 23, 2014 Absolutely superb craftsmanship. How did you re-guage the 071 axils and bogies? Quote
BosKonay Posted September 23, 2014 Posted September 23, 2014 Wow and wow again! How much better, prototypical and imposing does that 071 look!! Quote
Junctionmad Posted September 23, 2014 Posted September 23, 2014 I was wondering about doing copperclad with wide sleeper spacing in the fiddle yard. I think it could be a lot cheaper Quote
21mmp4 Posted September 23, 2014 Author Posted September 23, 2014 RedRich Hi, The re-gauge on the 071 is nearly identical to the 181, I used P4 Black Beetle NS 14mm wheel sets. These came on 2mm axles. The axles where changed for 2mm bright steel rod filled down to allow a BB of 19.88mm. The plastic gears are removed from the original and pushed onto the new axles (off centre) and a drop of thread lock. I have not required spacers or any removal of plastic! Quote
heirflick Posted September 23, 2014 Posted September 23, 2014 agree with the lads - she is stunning looking...and really looks like the real thing! well done sir! Quote
21mmp4 Posted September 23, 2014 Author Posted September 23, 2014 How are you securing the chairs to the track, pins, glue etc.? The chairs are glued to the Ply Sleepers with Butanone and in area's around the switch blades and nose, brass rivets are soldered to the rail and cosmetic chairs applied. Quote
21mmp4 Posted September 23, 2014 Author Posted September 23, 2014 I was wondering about doing copperclad with wide sleeper spacing in the fiddle yard. I think it could be a lot cheaper Hi Junctionmad, Copperclad with wide sleeper spacing works fine in the fiddle yard, However,Nenagh will only have two loops albeit 18ft long, and at this stage I find building the track easier than soldering up.

jhb171achill Posted September 23, 2014 Posted September 23, 2014 The re-gauging looks fantastic - interested to hear how this was accomplished. Quote

Cheers that's an ingenious method reusing the original gears on the new rod. What are using as a check rail gauge. The Scalefour stores don't seem to have them for 21mm. I was thinking I may have to use a digital caliper. The Jacobean dark oak dye seems to be producing a pleasing creosoted look on the sleepers. Nenagh is a fantastic location for a layout. The work so far is fantastic, I shall be looking in every day for updates, and will rely on your knowledge, so expect lot's of questions. Top quality, Rich, Quote
21mmp4 Posted September 25, 2014 Author Posted September 25, 2014 A few more pic's of Nenagh's track Quote
Junctionmad Posted September 25, 2014 Posted September 25, 2014 Are you using all plastic chairs for the points or a mixture of rivet and chair? dave Quote
21mmp4 Posted September 25, 2014 Author Posted September 25, 2014 Are you using all plastic chairs for the points or a mixture of rivet and chair? Dave Hi, I have attached a photo of the underside of a C10 21mm P4 point in the Album, this shows the area where rivets are used, the rest is just plastic chairs. Quote
David Posted September 25, 2014 Posted September 25, 2014 Lovely looking track work. Which ballast are you using? It looks very well. Quote

Dave Hi, I have attached a photo of the underside of a C10 21mm P4 point in the Album, this shows the area where rivets are used, the rest is just plastic chairs. Thanks, I presume you are supporting the crossing Vee, with rivets as well ? How come you decided to use rivets and not Slide Chairs for the switch rails ? Lovely work , Im really torn with avoiding 21mm ( cause I don't want to make oodles of straight 21mm track) I was even thinking of going EM dave Quote
21mmp4 Posted September 25, 2014 Author Posted September 25, 2014 Lovely looking track work. Which ballast are you using? It looks very well. David Hi, The Ballast is Woodland Scenics Gray B75 fine. Quote
21mmp4 Posted September 25, 2014 Author Posted September 25, 2014 Hi Junctionmad, Your layout plan for Limerick Junction is excellent, would be a serious amount of work if you went down the 21mm route. I started Nenagh in OO with Peco 100 track and got to a near complete layout before taking the plunge into 21mm. EM is a good option, at least you can buy the track in 1 metre lengths, but either way I recommend you use a finescale track. Are you able to see the rest of my photo's in the Album section of this site? You should be able to copy and zoom in on the details of the C10. Slide chairs are used but cut in two and used cosmetically. Quote
RedRich Posted September 25, 2014 Posted September 25, 2014 If you have a Peco large radius point you should place it next to the C10 in a pic to show the difference in size. I love the tie bars they look very neat. I'd say they were fiddly to put together and fit. Rich, Quote

Im ordering some exactoscale bits so will have a go at all plastic points etc dave Quote
David Posted September 26, 2014 Posted September 26, 2014 David Hi, The Ballast is Woodland Scenics Gray B75 fine. Thanks! Looks great! Quote
Horsetan Posted October 21, 2014 Posted October 21, 2014 (edited) .... What are using as a check rail gauge. The Scalefour stores don't seem to have them for 21mm. I was thinking I may have to use a digital caliper. .. No need: ye use the same checkrail gauge available for "standard" P4. If the Stores has none in stock, use a 0.68mm spark plug feeler gauge as a substitute. If ye want it "dead scale", use 0.58mm. 21mm is just so much more convincing than "OO" for Irish 5'3", whereas "OO" is almost right for South African / Japanese 3'6"!!! "EM" is almost correct if doing Irish broad guage in "HO"/3.5mm scale. Some of the Australian finescale modellers who follow the Victorian Railways 5'3" in "HO" have gone beyond "EM" and have pushed out to 18.37mm gauge. Edited October 22, 2014 by Horsetan Quote
21mmp4 Posted October 25, 2014 Author Posted October 25, 2014 Track laying and Ballasting on board number 4. Quote
Mike 84C Posted October 25, 2014 Posted October 25, 2014 Wow! extreme deep ballasting! But I like the track thats under it, thanks for posting. Quote
jhb171achill Posted October 25, 2014 Posted October 25, 2014 How did you re-gauge the 071? Would such a thing be suitable for a steam loco kit? Quote
