Peter, I believe RDG sell them , and I assume they will be at the Alexandra Palace model engineering show in January.

Cibie Z180 . A pair cost me a weeks wages from Larkspeed to uprate my Wolsley 16/60 headlights by 20 years in 5 minutes . Best money I ever spent .

Thread: Soldering brass mesh.
13/10/2016 22:14:43

Mike ,

In the past I have had the same experiences as yourself with mesh . Tried the gas torch route , and that was a spectacular failure . In the end , like JA I used a large soldering iron which I allowed to get really hot before using it . I found that if I thoroughly cleaned the mesh with clean emery , wiped it with Bakers Fluid and then tinned it with resin cored solder first and then went over with lead solder , it worked fine for me . Regarding stainless , it depends on whether it is austenitic or non-austenitic , which determines whether it is magnetic or not . If your mesh is actually stainless steel , then if required I can supply you with a small amount of solder specifically designed to soft solder it.

I hope you will find this information of use .

Scrumpy ,

Would the Stuart Models dynamo be suitable , albeit expensive ?

Thread: Bronze Bearings

Michael,

My suggestions would be that after rough boring you use the boring tool to create an annual groove in the bearing directly under the oiling point so that some of the oil can easily travel to the bottom of the bearing . Then turn the tool so it is pointing down and create a stopped groove running out along the bottom of the bore either side of the annualar groove so as to distribute the oil . In this way oil will always be available instantly upon start up and so extend the life of all mating surfaces . You should also obviously use the stoutest boring tool you can get in the bore in order to reduce spring and thus avoid bell-mouthing . Repeated final cuts should obviously be taken without any additional cut being applied . The finer finishing cuts should be applied using an angled top slide so as to allow you to better apply small cuts . In addition , you will find it beneficial to change the feed to a different feed , and preferably one which is not a permutation of previous feeds . In this way you will have a better chance of removing more of the peaks from the final surface finish.

Thread: Welding
26/07/2016 09:03:57

Alan ,

In my experience thorough and sustained both pre and post heating are essential if the repair is to stand any chance of permanence . The last CI item I welded was a bench vice . I thoroughly pre- heated , then used a No 25 nozzle on o-a to complete the weld , before carefully put the vice in a dustbin full of sand for 24 hours . Vice is still in use many years later . If you know anyone with oxy-acet that can do the work for you , but who lack the materials , I can supply you small amount of rod and flux to complete your work for the cother of the postage . Alternatively you may find Cast Iron Welding Services in Coalville on 01530 811308 ( no connection ) helpful .

Thread: Repairing cracks in cast iron

Speedy,

Since you have Oxy-Acet available , you are welcome to a suitable cast iron rod . One will be more than enough for your needs . No flux yet , but will be ordering some this week , so you welcome to some of that too . Would suggest you thoroughly pre-heat , use a large nozzle ( I used a No 25 on a Sapphire shank to weld a broken vice ) , and then cool as slowly as possible . I buried it in a metal dustbin full of clean sand .

Thread: Custom paint suppliers
26/11/2015 19:54:30

Anna , My alternative suggestion would be R J Stokes . Full contact and company details on www.rjstokes.co.uk Quite a few years ago I had them mix up a litre of special paint and it was excellent . No connection with company other than as a satisfied customer . Hope this helps . Trevor.

Thread: Myford lathe values.

There was an old piece of legislation called the Trucks Act , which stated you had to be paid within a set time after your working period . Not sure if its still in existence , or if , like many others , its been repealed .

Thread: rectangular faceplate?
15/10/2015 20:33:48

In my humble opinion , if there's a reasonable possibility of something going wrong , then its inevitable it will do so at some point . So do not try to accomodate the problem , rather resolve it and remove the corners. Machines do not take prisoners , only victims. Have been unfortunate enough to have witnessed far too many similar life-changing events during my working life .

They also supply a large range of styles of quality tooling arbours and collets . NOT CHEAP, but good . No connection with company other than as a satisfied customer. Hope this helps.
