Re: A machining question.
Gents, Thanks for the advice and questions that have made me think... Accuracy needed? Visually irrelevant, good enough to work - I've no idea what that means numerically! Number needed? Three (so six suspension links), so no need to think of "mass production" unless the carpet god gets ve...

A machining question.
I was wondering if anyone could suggest a good method of making the part shown in "C" (with fittings) and "D" (plain) below: the side elevation is in "B", "C" and "D" are views from underneath. Capture.JPG My initial thoughts are milling (but I'm not...

Little & Large 4 - The Socially-Distanced Challenge
Progress! And a request for help. Things have moved slowly as, to relieve the tedium of fiddly bits, I've also built a Slater's van kit that has been in the cupboard for over 10 years: and there was the garden and good weather! Little So the CAD drawing was resized differently in the x & y direc...

Re: Exactoscale wagon chassis kits
By chance I've been working with similar problems. As an interlude from the lockdown challenge I decided to do something simple and build a Slater's MR van kit and fit it with Exactoscale suspension bits that I've had in stock for many years. I used the conversion bits (solebar and W irons as single...

Re: Single and Double Slip Operation
If you want to have a nice plan drawn with software then Templot, but for this purpose pencil and paper is much quicker if you have a scanner. Without a scanner a sketch using 'Paint' will also do. Suggest using coloured pencils - at least three, one for each "+ve and -ve" and one for the...

Re: Little & Large - The Socially-Distanced Challenge
... I made up a true faceplate from a lump of brass to secure the tyre to with double sided tape, having removed the moulded centre, after all I was only taking gentle cuts, and I wanted to be able to remove the tyre without distortion. It took a fair time even taking a fraction off at a time, and ...

Re: Socially Distanced Challenge – CR Class 488 Build
Lovely.
I’m looking forward to following this as I’ve a wish to model an 0-4-4WT (with open cab) and have always thought that hiding the motor and gearbox could be a challenge, as will getting the balance right to keep it on the track and able to pull a decent load.

Little & Large 2 - The Socially-Distanced Challenge
Not much progress to report as the weather has meant the garden took priority!

Little & Large - The Socially-Distanced Challenge
LITTLE It became clear as I was doing the model drawing that the original had highly detailed and dimensioned boxes but the underframe was probably best regarded as the equivalent of a loco weight diagram - a good impression but not necessarily correct in all aspects. So the changes & assumptio...

Many thanks for the leads. I hadn't realised that Rumney Models did anything other than items much too modern for my projects! I'll contact Justin for information.

Re: Little & Large - The Socially-Distanced Challenge
can I turn the stanchions? I have doubts about my abilities. Looking at the drawing Andrew, the stanchions look to be parallel above the solebar so they may have just slide into the "socket". Perhaps a plain length of rod/wire of the appropriate diameter and a piece of tube to suit. This ...

Re: Marking gauge?
Here's mine with a frame spacer marked out with it. marking gauge.jpg If I were making another I'd make the guide a bit bigger and possibly have it on a screwed thread to make precise adjustments a little easier. Perhaps, without a lathe, start with a threaded rod, nut for the guide, lock nut to hol...

Re: 7th Chris Kedgley Skills Day
From me as well, very many thanks to all involved with putting on an excellent event. I went hoping to pick up some ideas for solving some of my problems and came away with those and quite a number of extra items as well.
Roll on the next one! (The hunt starts for topics to bring.)

Re: end steps
Have you thought about making a master, moulding it and casting them in resin? You might have a high failure rate at the actual casting stage, and they'd be fragile in life, but it should be possible - I've cast down to 10 thou before, albeit for parts which will not be knocked. Thanks for the sugg...
