No problem Geoff,

You do that or pay using paypal and I will post to OZ, either way I am happy.

The good news is I am up to about 20 units now, which could help with the price.

I wonder if the 7mm narrow gauge society would want some for their store, could help with the numbers?

Any one a member and able to ask for me?

James Hockley?

Hi James,

Please put me down for one as well, I live in Australia, but I can send you a Barclays Bank Cheque and give you an address in the Black country to send it to.

I am now up to 15 in total.

I have had chat with Malcolm from Model Railway Parts, at these kind of numbers the gauge will come out around ?9.

Obviously a little more than his O gauge item, but he makes many more of those.

If the numbers go up the price will come down.

I will handle distribution of these in the first instant, expect postage to about 80p as they should go in a large envelope, over seas will be at cost.

Is every one OK with that price?

Lead time will about 4-5 weeks.

James, many thanks for taking this initiative!

Just to repeat my confirmation from the NGRM-online forum so that you have my e-mail address attached.

As for?proper use of the Yahoo?group, in my opinion, absolutely!

best regards from Sweden, George!

The interest in this is looking good, thank you guys.

There is no great rush, Malcolm won't be making them for about 4 weeks, I have a list going of who wants what, if the numbers go up any price reduction will be passed on.

I am not intending to make money out of this, just cover the costs.

I will not ask for any payment until they arrive.

Closer to the time I will email a list of who wants what, to ensure no one has been missed.

I hope this is proper use of the Yahoo group.

I am in the process of getting a back to back gauge produced for me by Model Railway Parts. I have been after one for a while, I am aware of what is on the market but they are not quite what I am after.

The gauge will be similar to the standard gauge one they offer at present

The back to back will be 12.4mm.

At present I do not have a cost for the item, as with all things the more I order the cheaper it will be, so I am looking to see what the interest in such an item would be.

I have ordered 5 to start with but if more people are interested I can get a price on what an increased order would be.

If you are interested let me know.

I know several people have made excellent ones, but I do not have the skills or equipment to do so.

Please tell Malcolm that if he wants to make this a standard product (or make a few extra for stock) then we can put details and links on the O14 group website.
And Adrian may want to put details in 7mm NGA News.

Hi James

I have always seen this Group as an online self-help group and this sort of project is real and practical self-help.? You are to be applauded for your initiative (and doggedness, I know how long you have been after one of these).? The availability of more 'home-grown' solutions, tools and jigs can only help 014.? Well done.

Now does someone fancy producing a three-point track gauge so I can get consistent gauge widening on curves?

Cheers

David

David,

Make your own, buy either a three point gauge in 00 finescale or EM.

Make yourself a few inches of 14mm dead straight track gauged with callipers.

Cut the bought gauge in half, and take a few mm out of the centre. Place one part on each rail of your standard track. Apply Araldite to the top surfaces. (File flat first if there is any raised lettering). Put a piece of metal, almost anything will do, on the Araldite. Weight on top of the rails so the whole lot goes flat, or clamp, hair grips, plate and gauge sections. The other way is to build it upside down with the track rail down on top.

?

Go to bed, Araldite will have set by morning.

?

I'll be offering one of those as well, if I can find it!

Thanks for that!? Your pragmatic method is an awful lot simpler (and more foolproof?) than the method I had previously attempted - and failed - which used a triangle of brass, three carefully drilled holes and three 4BA bolts soldered in place with the screw slot widened to accept the rail section of my choice.? Try as I might I just could not get the accuracy I needed; but the gauge widening worked fine!

Does anyone make a three point 00 track gauge anymore?

Cheers

David

David,

Worth trying anyone doing finescale track, Carrs maybe, or is there a society?

?

Your bolt method works fine, widen the slot first, drill the plate oversize and Araldite the bolts with it sat on your 'standard' track. There's then no stress on the bolts whilst they set.

Hi James
Yes I would like one.
Will the gauge be similar to their O gauge one and show the maximum back to back of 12.50 mm as well as the minimum of 12.40 mm as in RCL standards?

Hi Julian,

I had not planned to have the gauge done in that way.

It is possible but would increase the price due to the increased production process.

I can discuss the options with Malcolm when I see him on Sunday and see how that would affect the price.

Hi James,

Okay still count me in for one whatever you decide to go ahead with.

Up to now I have been using G.W. Models adjustable back to back for 3mm scale, it goes from 10.3 to 12.8. ?Which is handy for ?moving 16.5 wheel sets, as you can set the back to back for each wheel ?to be moved along the axel so as to be equidistant from the centre. I use an axel push made by Fahrmann. Even so a fix gauge will be very useful.

Regards

Julian

Given the level of support from individuals 7mmNGA Sales cannot justify?buying stock.

Sad to say, the collective memory of the?volunteers who man the Sales stand cannot recall being asked for a B to B gauge?for 14mm gauge!

Thank you every one who has asked for one.

Currently up to 28 units. ?I might round it up to 30 and sell a couple on the Narrow Gauge online forum.

Closer to when they are produced I will ask everyone to email me personally with confirmation of order and address details.

Thanks for all the interest so far.

I will update on Monday when I have spoken to Malcolm on Sunday at the O gauge show in Bristol, with any luck a slightly better price, no promises!

James,
I noticed that Romford [Markits] have a back to back gauge which is 12.8mm., I don’t know what these gauges are going to cost, but was going to suggest looking at what these Romford gauges cost and just putting them in a lathe and running .4mm. off.

Hi Brian,

I agree that would be a good solution (I think they are for 3mm fine scale), but I don't have access to a lathe or the knowledge on how to use one. ?If I did it would a good method to produce a gauge.

I am quite far advanced down the road of getting this gauge sorted and I am hoping the price will come down a bit as I can place an order for 30+ units.

Dear All,

Re the proposed back to back gauge being proposed. Note that the min-max of 12.40 to 12.50mm applies ONLY if you have the matching wheel profile - which is that proposed by the BRMSB as ‘EM’ in 1950. This profile was used by Alan Gibson and MayGib and sold by them as ‘fine scale OO’ during the time I was developing and producing my range of O14 kits. I took wheels from both, the loco tyres coming from Alan and those used in the rolling stock from Ken Pelham at ?MayGib. I moulded my own centres in polypropylene - the rolling stock axles were purchased jointly with Alan Gibson in batches of 20,000 (split two ways). Alan sold them for ‘ TT fine scale’.

Use of any other wheel profile will cause varying problems - good tracking is only assured if standards are kept to quite strictly - particularly on locos with more than two axles. Mixing profiles, especially those un-published is risky.

My standards were the result of practical experiment - based on the old BRMSB measurements and logic. They allowed perfect tracking of small four wheel locos and wagons around sharp radius curves without derailment, either pulled or propelled. A long time ago I did propose that, for models of larger two-foot gauge prototypes, it would be better to adopt modified NMRA ‘Sn3’ standards - which are more sophisticated than those of the BRMSB - which were more guidelines.

Thank you every one who has asked for one.

Currently up to 28 units. ?I might round it up to 30 and sell a couple on the Narrow Gauge online forum.

Closer to when they are produced I will ask everyone to email me personally with confirmation of order and address details.

Thanks for all the interest so far.

I will update on Monday when I have spoken to Malcolm on Sunday at the O gauge show in Bristol, with any luck a slightly better price, no promises!

Regards?

Hi James,

Could you please put me down for two back to back gauges.

One of them is for a friend.

I’m in Australia.

Roy,

Can you suggest to me a s newbie a min-max other than 12.40-12.50 that you feel would have wider applicability to O14?

Many thanks

Gary

Dear All,


Re the proposed back to back gauge being proposed. Note that the min-max of 12.40 to 12.50mm applies ONLY if you have the matching wheel profile - which is that proposed by the BRMSB as ‘EM’ in 1950. This profile was used by Alan Gibson and MayGib and sold by them as ‘fine scale OO’ during the time I was developing and producing my range of O14 kits. I took wheels from both, the loco tyres coming from Alan and those used in the rolling stock from Ken Pelham at ?MayGib. I moulded my own centres in polypropylene - the rolling stock axles were purchased jointly with Alan Gibson in batches of 20,000 (split two ways). Alan sold them for ‘ TT fine scale’.

Use of any other wheel profile will cause varying problems - good tracking is only assured if standards are kept to quite strictly - particularly on locos with more than two axles. Mixing profiles, especially those un-published is risky.

My standards were the result of practical experiment - based on the old BRMSB measurements and logic. They allowed perfect tracking of small four wheel locos and wagons around sharp radius curves without derailment, either pulled or propelled. A long time ago I did propose that, for models of larger two-foot gauge prototypes, it would be better to adopt modified NMRA ‘Sn3’ standards - which are more sophisticated than those of the BRMSB - which were more guidelines.
