Re: Who would want a form tool for re-profiling wheels?

Hi Terry, Please put me down for one. Hope to learn eventually how to use something like that so should buy one whilst they are available. As a matter of interest there is a German company who sell them for other profiles and the cost you mention sounds appropriate. https://www.fohrmann.com/en/railw...

Re: The Virtual Scalefour Society Stand

Excellent show, well done to everyone for setting this up. Particularly like the layout presentations and some of the in depth talks on how things are done. Wonderful stuff.

Thanks for making this possible under such difficult circumstances.

Re: Ralph's workbench

Been diverted onto DIY projects now that we are able to get the shops and buy things so modelling came to a halt for a time. Got back to things today and the delay has given me time to think over the project I am currently working on. 44456 is running on a Bill Bedford 4F chassis and it runs very sm...

Re: Progress with Slattocks Junction

Took longer than I expected but managed to do some testing yesterday with this RTS Grassmaster. I was using all the products I purchased from Microrama and the results were, to me, very encouraging.

Re: Progress with Slattocks Junction

First trial of the RTS machine has proved very encouraging but I have had to prepare more bits of expanded foam to work on to check out the results. I expect to be able to show more results in the next few days once I have had chance to get to grips with this machine.

Re: Ralph's workbench

Having gone through a mammoth workbench tidy up I thought it would be useful to have a stand to hold some metal sections in so I drew up a design and cut this out on my laser cutter. 2mm MDF which is a pain on the Emblaser cutter but after a few hours work a suitable stand came out. I passed the ide...

Re: Ralph's workbench

Its been a while since I wrote anything but I have been busy. I decided to stop work on the sprung tender chassis for the 4F and change it to a different design along the lines I used for the A Class locos. These have a milled brass block chassis which gives low down weight in the tenders and make i...

Re: Brassmasters Blk5 45232

Hi Dave,

I use this solder most of the time with a phosphoric acid flux and set the iron about 350 degrees. Love it, it flows beautifully and I rarely have to clean up after that.

Love the Black 5 Dave, superb work.

Re: Ralph's workbench

Thanks Dave. Have you thought about selling your jig for putting wheels on square? Yes, I did but so far the reject rate has been pretty high so for now it is a non starter. Once I have got a working version you will see what I mean. Colin Wrangles is sadly missed, but I have one of his locos, a con...

Been a while since I posted but I have been beavering away with things. The L&Y locos have had their chimneys changed and now, thanks to John Redrup and help from L&Y Society boys sending me in that direction, they now have brass lost wax castings which are a bit more circular than the cast ...

I took a look at Lightburn but I don't think it supports the commercial machines like my HPC laser. Hi Dave, It is always worth dropping these guys a line as they are very helpful and obliging. In view of the number of HPC machines around they may well be interested in adding in a driver for it - I...

Re: GWR Steam Railmotor Chassis

Those windows look nice Jeremy. The Photon never ceases to amaze me at what you can do with it, I did try doing some boiler washout plugs the other day and kicked that into touch, perhaps a mite too small but otherwise it is a brilliant piece of kit.

Re: Ralph's workbench

That is very interesting Dave. The Slattocks group have some Black 5s which were built using Hornby bodies with a Comet chassis, Mashima motors and Roadrunner+ 40:1 gearboxes. Whilst they ran perfectly the speed at which they ran with a passenger train was, in our view, far too slow so the ratio got...

Re: Ralph's workbench

Thanks for your encouragement guys. The second loco is now running much better after stripping down the tender, the tender wheels were dragging on the sideframes so did a bit of thinning down and now it runs well. Moved on to my good old 4F. Now this has a long, long history. It is a real combinatio...

Re: Ralph's workbench

Things have progressed since the last post and a lot of detailing has taken place. One loco is running perfectly, the other still needs some tweaking which is tomorrow's job. Need to get a couple of brass whistles and some chequer plate for the fall plate. Getting there.

That goods shed is going to look superb David. I usually find when brick lines don't come out right that it is down to me putting in the same line twice (or sometimes even more times) on the drawing and normally because the step and repeat function gets cocked up (by me!).

I see in all those fine looking bits that the drive shaft has the pins at right angles - they should be in-line in order to achieve a constant velocity drive and minimise wear.
