PGA accuracy


Recommended Posts

Which PGA is more accurate, the Lima one or the Hornby one? I kinda got a half rake of both and want to swap the ones I didn't want for the better items.

Cheers

The lima and Hornby PGA's are different wagons so its not quite as simple as which one is better. I personally prefer the Lima, but it has an unfortunate mix of details that Lima obviously didn't spot, so it isn't actually right for any of the different batches.

will give an idea of the more obvious differences between the PGA's that the Lima model might represent.

Didn't realise there was more than 1 type of hopper. Thanks for the heads up. I'll have to do a bit more research into what I want to achieve

Believe me, there are (or at least seem to be) dozens of slightly different types; almost as though they lost the drawings between batches, Someone did an article in the DEMU magazine, which got to about fourteen types; I suspect uniform rakes lasted for weeks in service, before they started to get mixed up.

PhiL Eames did the very informative article for the DEMU UpDate magazine split into 3 or 4 parts iirc. The Lima and Hornby models are a good starting point for some simple modelling to transform them into something else based on the body and chassis designs.

The links in that article are out of date, my PGA photos are in http://paulbartlett.zenfolio.com/poaggregate

 

There is mention of removing the bulkhead. Although completely correct there was a bar across the centre line of the earlier batches of Yeoman hired hoppers http://PaulBartlett.zenfolio.com/yeomanpga/eb517d92The very earliest ones appear to have two. http://PaulBartlett.zenfolio.com/yeomanpga/e206702b

PS Brian, I'm not convinced they didn't lose the drawings during the building of batches. For someone modelling them later in their lives - the later 1980s no two appear to be the same.

I've probably already asked this on another PGA related thread, but can't find the answer if I have, so sorry in advance.

I've got a couple of bashed about Lima PGAs that have lost one or more buffer.

What would be the best way to replace theses?

Which/whos buffers do I need to purchase?

Ta. :)

I think these are the closest I know of:- http://www.lanarkshiremodels.com/lanarkshire%20models%20and%20supplies%20website_106.htm

Even if only one buffer has gone, it's best replacing both, so they're certain to be the same length. From experience, I'd use a fine drill (1mm or so) to pilot drill, then drill out to the final size. Buffer-beams are very prone to splitting. If you've a few to do, it might be worth making a jig with a bit of brass angle as well, to make doubly certain you've constant buffer centres.

I used 16" sprung Oleos from 51L. I think they do castings too in case you have damaged the mount.
