Hi Guy I will start with. Making a D cutter. It would be easiest to take an old .5mm drill and grind off one side and the sharpen to a point either in the middle to make a pin point or one side to make a cutting edge. or both sided and make a paddle drill Making and hardening some silver steel is th...

Hi Andrew Talk to the horses mouth ring up David White at Slaters they do there own waxes and send them on to the Jewellery Quarter to have them lost wax cast Basically you need to make a master which is 3% bigger than the finished product because you are in effect casting it twice once in wax and t...

Thanks Terry and Phil for your input. There are various ways of setting out the holes in the disc the important part is finding the centre and working out from there. Moving onto the hinges I have made a 3:1 pattern of the hinge for the Pantograph Milling Machine, and cut it out in 10 thou nickel si...

With the correct diameter of 34.4 mm I have shaped the door's corner using a shaped cutter. I made it that way round on purpose so I can clearly see what I am cutting. IMG_6039[1].JPG IMG_6024[1].JPG This is one of the reasons why I did two disc as this cutter needed to be in the right position for ...

My Next project again for the 7mm scale SR Lord Nelson Class is the Smokebox Door. Like the Chimney it will go for casting. It will fit in a recess in the smoke box front etching. SB DOOR 2.jpg So first of all I need to cut a large disc in fact I cut two. Now putting the block in the lathe I find it...

Hi Richard You mention you have a lathe and assuming it has a jacobs chuck for the tail stock. Would it not be the simplest to make completely new 3/32 bearings to suit Machining the ends of 1/8 axles to 3/32. I would not recommend using a 3, 4 or 6 jaw self centring chuck. All self centring means i...

Hi Simon
Yes I can do them. How many have you got?

IMG_5960.JPG IMG_5961.JPG With the main base shape made I need to add a ring of Rivets to the base of the chimney and to do this without a boiler to sit on I made a plastic box which I could slot the chimney into. IMG_5964.JPG I have marked on it the centre line, and the outer radius on each side. ...

I agree with Keith. You are not actually measuring the gauge in that picture merely the distance between the two rails it should be wider that way the gauge needs to be perpendicular to the running rails

Hi will I would not bother with the sprung loaded ones, I've had them and find the spring a waste of time especially with the smaller drills. Like you, mine are not holding what they used to. I found the answer really is not to change the drill bit very often, I change the drill instead. When it won...

Turning a chimney in Two pieces Sometimes it has to be done and this is one of them. I have been asked to do a chimney for a 7mm kit for the SR lord Nelson class and at first glance I thought that would be easy enough. Well I was wrong or it was going to take allot of filing. My first attempt went w...

Moving onto the Interior Some of the parts are on the body etch and others are on the roof etch. IMG_5588.JPG IMG_5768.JPG First of all make sure the floors fit in there respective places, file to length if necessary. Now starting with the low partitions, they need to be laminated back to back so th...

Ooh - I can detect a can of worms opening! If this effect comes into play every time there is a bend radius, does that mean there is a danger of cumulative error where there are several bends on the same part? I have a specific example in mind: forming the 4 bends at the corners of a tender in 0.3m...

Hi Mike Just been playing with the single wheeler and been running it with 5 bogie coaches weighing about 225 grams each. Its only an end to end layout so can't run the train very far. There is a little bit of wheel slip but I probably have 95+% of the body weight on the driving axle. There must be ...

A correction to my earlier post its not .3mm I use its 10 thou or .25mm so the numbers need to change from .3mm to .25mm and.6mm to .5mm One other point I thought about since posting earlier, is roll or curve the outer edges before the middle that is trap the edge and pull round a bar of a smaller d...

Hi Alan I think its a bit of a tall order getting tube that Diameter and that wall thickness I would say that .5mm is a probably the thinnest you can get. Some of the early Brassmasters kits supplied copper tubes with a 2mm wall thickness. which I have used a blow torch to fit smoke box rappers and ...

Turning Lancashire and Yorkshire Whistles. I get an order quite regularly for a quantity of these, and they need to be done quickly without mistakes so I use a jig. IMG_5823[1].JPG The jig fits in the tail stock and slots over the 1.2mm wire. Its made from an old axle drilled and milled to under jus...

Hi Mike
The Loco now pulls the tender and 5 bogie coaches at least will take a film of it when I put the coaches back together after I finish painting and doing the interiors.

Hi John Not sure if Emco are still going but spares do come up on Ebay or you could try Pantograph services http://www.pantograph.co.uk/ The do supply spare brushes for my pantograph milling machine which has a similar motor to the Unimat and the defiantly sell Bushes as i have bought some a few yea...

Apart from the challenge, I assume this is about keeping the wheels on the track all the time to give better pick ups. You don't say which gear box you are using I thought there are some which are slim enough for use of hornblocks in OO. You could allow the driving axle to move up and down with the ...

[quote="ralphrobertson" Whilst trawling for inspiration I came across this photo on the Manchester Libraries site which is of shops actually on the opposite side of the road from the one I am using. The photo was taken on the 8th March 1959 and shows just how amazing road vehicles were at ...

Hi Dave not sure if these help 46109 at Low Moor Not found any of the Rebuilt Scots where you can see clearly in the dark underneath. img20201020_19270207.jpg 46109 Low Moor 24.9.61 img20201020_19280413.jpg img20201020_19433836.jpg 46122 Crewe North 22. 10.49 With steam coming out is anything more v...
