Hi Ray,

The valve gear as drawn by LBSC is very poor and I would recommend using the updated design by Don Ashton which was described in Engineering in Miniature January 2008. I can let you have a copy if you don't have access to it. I also redesigned the valve gear independantly of Don as I didn't realise he had already done it! Both new designs give much improved valve events.

You will need to update the boiler design by fitting bushes for all the fittings. On the drawings the blower valve and water gauge screw directly into the backhead and the top feeds screw directly into the boiler barrel which is not allowed now.

I started drawing PG in 3D CAD and found a few errors so far. The hornstays are shown as 3/8" wide but should be 5/16" to match the horns. Also if the front bogie stretcher is fabricated using brass angle, the angle obscures the bottom cylinder mounting holes in the frames.

Hi Ray,

Ok will pm you.

Just to wet your appetite, here's a photo of a very nice chassis being built by David Williams taken last Sunday at our 40th Anniversary Rally at Cheltenham.

If anyone has a part built Purley Grange in 21/2" gauge (in any condition) or any redundent parts and wish to sell them PM me.

Since starting this thread i have progressed somewhat, the main frames incl. axle guides, as in pinture from John, Bogie complete, axle punp, regulator and a few other small bits and pieces.

I would still be interested in hearing from anyone who has built the PG from LBSC or in any parts for sale, incl. built or part built PG's.

Hi Ray,

How are you getting on with the Grange? I have the beginnings of one and have just started work on the boiler. What other issues have you found with the deawings to date, please?
