Don Young's Black 5

[jools]

Hi everyone

I've been reading this thread from the beginning at 2009 and was expecting it to have petered out, so I'm really glad its still active.

Its been a lifelong ambition to build my own steam loco since seeing the live steam models giving rides at Ingoldmels near skeggy as a child.

work and family gets in the way but now I have taken delivery of a set of DY plans from AJ Reeves so its only take 50 years in the planning stage!

given the time it seems to take I'm beginning to wonder if I left it too late.......

Look forward to reading more from the experts I here, as well as those just kicking off like myself. I suppose I'm fortunate to have a garage full of machinery to put to good use.

My first question - given that 3 D printing has reached the realms of availability, I wonder if there is a way to use this in producing casting plugs ?

cheers

Julian

Excellent advice guys, i dont suppose anybody here has them scanned in?

Hi Max,

I suspect they are too large for your average home scanner, but some of the commercial places might do it.

like you I intend to draw up the sub assemblies on AutoCAD a3 or A2 "sacrificial" sheets. I've also found that printing at full size (for 5" scale) they can be glued to the material to assist accurate marking of hole centres and datum points.

I also noted that many of the previous images posted are no longer available due to Photobucket no longer supporting 3rd party sharing, unless you pay a monthly fee.

I recently changed over to Flickr, which was a right royal pain in the butt. I had to download all my images from Photobucket then open a Flickr account and upload them all again.

In other forums I then went back through my posts and replaced all the image links.

As I re draft these plans to add decimal measurements rather than fractions, I'm wondering what sort of rounding off in terms of decimal places I would use?
This redrafting in itself has shown up areas that have missing dimensions difficult to determine, probably due to them being castings.

Although trained in the UK during the period when both imperial and metric machines were in use, I have long been a metric convert so its taken a while to get back over the fence so to speak. This raised another question should I just convert the drawings to metric and be done with it..................decisions

hi Jools

just realised that you are posting in the good Dr's thread, I'm afraid that this build will not go any further, the good Dr passed away IIRC about a year ago...

Kind regards

Pete

I see no reason not to continue this thread as a way of helping each other to build a Don Young Black 5. Of course it's sad to loose the originator of the thread but there has been revived interest in it recently.

Now, here is a part I struggled with when I was first starting in the hobby. I made mine by grinding a tool to the curved contour and making a long strip in the shaper then turned it over and shaped the step, drilled the holes and then parted them all off. Quite a job for a small part but I learned a lot from it.




Move on thirty-five years and new technology is available! If you're building this model this will save you a lot of time to have a set of these spring grippers supplied as a lost wax casting. Get in touch if you'd like a set.
