I must be mad posting this but the Aspinall has come home and I am going to build it. Now I have the drawings but this has never been described in any magazine so it is very much like climbing a mountain in a blinding snow storm without a Zimmer. Some bits are quite intuitive but other bits are a nightmare so I hope you will not get too tired of endless questions!! Just putting you on notice in case you want to emigrate! Cheers david

My first dilemma, the brake hanger. The buckles are fine. I have about twenty hangers in various states of ‘ready for the bin’ as I cannot file the curves. I can drill the 5/16” hole to do the inside of the curves but the outside is a challenge. I even have a jig to solder on the little bit at the bottom. Can one mill something like this? Or do CNC machines make things this small? Yours in frustration PS these hangers have stopped me for about ten years on this project., along with work, grandchildren, wifely projects etc of course!!!! Cheers David

You could drill the 5/32" radii too, and then you just need to file that around to blend into the straight sides. And you could make hardened toolmaker's buttons with the o/d to suit the outside curves and a spigot turned to fit into the 5/16" hole. Make two, clamp them on each side and file down to their edges. Hope that makes sense!

Taking a quick look I think I would tackle these in the following manner. start with flat bar to match the hanger.. looks like 15/32 x 9/32 leave over-length for now. Mark out the positions for holes and outline, while in this block state drill all holes in their positions, No.43, the 3/16( to depth) and on the other face the other 3/16 and 5/16 holes. Machine the 3/32 tongue ignoring the collars around the 3/16 hole, I'd braze suitable rings onto these later. now you just have the filing for the inner 5/16 square section, outer curves and small radius for the bottom 3/16 hole which can be done once the two collars have been brazed in place using them as a guide. I'd tackle the outer curves using a belt sander as I did for various parts on my Doncaster build, this should be pretty straight forward as you still have a squared block to rest on the sanding table with, final work can be done with a file and sanding pads to get a polished look. Like all things in life there are many ways to tackle a given problem.. this is how I would do it although admittedly I've only briefly looked at the design. Hope this helps.. Pete

It's not too small for CNC - it might make an amusing project. The trick - as with so much machining, is to figure out the workholding.

Hi Dave & Pete
Thanks for your help. Dave, the idea of hardened tools makers buttons must be in ME 201 , I am still doing ME 101! So Pete, dix points! I must confess that on reflection I did not have a miller / driller last time I tackled these so the drilling in the correct position is going to be much easier. Also your idea of SS two rings is appealing, I set up a jig to SS a small tube into a semi circluar 9/32 hole. Two smaller rings will keep the axis straight and true. And the belt sander. I must confess to correcting all sorts of errors by brute force using sanding disks and I even made up several to put in the chuck and put the item on a small table in the cross slide. This is great for getting a polished surface using 1000 weight paper and lots of oil (and getting very dirty!!!!) I was ashamed to admit to such crude methods but if someone who can build a bloody great pacific does it, so will a little 0-6-0!!!!! Many thanks Now off tomorrow for a week on the Kennet and Avon in a canal boat with my drawings to work out how the make the rest of the tender and then the engine itself!!! Wife thinks I am bonkers.
Cheers David

Can't be milled complete, can't cut the square corners on the inside. I've looked at this one already.... I did wonder about wiring the profile out of the right thickness plate, then it would just need the ends rounding off and the holes drilling, but that leaves you drilling a half and half hole...

It is with great trepidation that I even start to think of this as a build thread but I can report that I have made the brake gear (well most of it) for my Aspinal tender and the blanks for the rail guards. Just need to bend the damn things. No pictures as I am not a pro but thanks to the postings of greenglade et al, I actually drilled holes along the outline and removed the extraneous metal and the finished them (guards that is) on a sort of linisher. Quite remarkable! They look ok! Perhaps I will open myself to ridicule with a picture soon. Until then thanks chaps for your inspiratrion. David

Hi David I doubt you'll find ridicule here...they've a friendly bunch... .. well done on getting started.. before you know it you'll have a rolling tender chassis.. it's the little bits that take the time... Kind regards Pete

Well just woke up! Spring has come, workshop open although not dried out yet as the door will not open fully, Girlie had a full hip operation last week so I am wearing a very smart nurses uniform but on Sunday, I had a full afternoon clearing up and perhaps progress might be evident. I have to confess that this is not to show you my brilliant work but to merely put you on notice that endless advice will be sought as I am not an engineer, just seeking to be one. Also now the Chairman of the Southampton Society less time for the best job. First job is to make new valves for the Princess so I can get Derek Brown’s injector working (Yes Julian still doing that), and then onto my little baby Aspinal! Just hope I live to 150!! Cheers David

Next challenge is to find the tender brake shoes. I have tried Reeves and Blackgates with no luck even though they sell wheels with the correct diameter at 3 7/8". I have shown an extract from my drawings, if any one has a clue I would be most grateful!! Ii ttied to upload a drawing but I am told the forum attachments are full whatever that means!! Will try later. David s1158.photobucket.com/user/brigandchief/slideshow/Try that!

Hi David
Have you tried asking Malcolm at model engineers Laser, he does a fair bit for Aspinal although admittedly the brake shoes aren't listed.
Cheers
Pete

David,Im building a MSWJR loco it has a similar tender and i used the brake shoe ring from the Glen,they are very similar and there is plenty of meat on them ,hope this might help. Garry

Hi David, I put an earlier post here offering you a set of brake shoes along with a photo of a stick of 3 of the shoes and thinking I had the other three. When I went to check a couple of seconds later I discovered the other three were for a loco!!!. I don't think a 75 yo has moved quite as fast to get back and delete the post before it was too late. I do apologise but if three are any good you're welcome to them. The three now orphans. Jim

Thanks Pete, Garry and Jim.
Pete, have emailed Malcolm and he is going to make them from steel. This is after all just a parking brake so making them from cast iron is a bit unnecessary. Now Jim thanks for your offer, I suppose I could come to Australia to get them but even though I live in Southampton the sea voyage would take me away from the railway for too long, so sorry about that. But Garry, now off topic a bit, I have a Midland 'O' gauge in the attic and the other day I found a used book on the Midland that showed a LSWR loco at Hendon station with two LSWR carriages, one from Portsmouth and one from Southampton and they were through coaches to Manchester and Leeds. It must have been a long journey from Southampton to Leeds but what fun!! In future I will run an LSWR through coach and a GWR (horror of horrors) through coach, Penzance to Aberdeen. So I would really love to see your MSWJR loco in all its glory one day on our 5" track here in Southampton. And as I am now Chairman of our club it would need to double head my Princess and certainly get first right of way!!!!
Thanks guys, back to the Aspinal!! David

I know Jim is into 0 gauge too.. actually I wouldn't say I'm into it, more like at the beginning of hopefully a long venture into model railways when I can't handle the heavy stuff any more.. BTW have you seen the new partwork magazine to build the Mallard in 0 gauge, yes it works out a little dearer but I've subscribed anyway. My reason being that if I was to buy a whole kit ( i already have a Martin finney Gresley A1 with corridor tender under the bench to do) it would take me away from 4472, a monthly delivery of 4 magazines would only require a few hours of my attention. Seems like a good plan to me and would be a small break from doing the big un, nothing better than a little relaxing watching TV while building a model on your lap... well actually the computer desk but you get my drift...

David, That a deal,as they used to run from cheltenham to southampton,That would be great,Its being built here in cheltenham (real one was stationed at chelt) and a run in southampton would be very fitting,It is a 2-4-0 no 12 a crack express of its time,finished in lined crimson lake,but about a year away,but ill hold you to it,so stay chairman for a while,also check out SWINDONS OTHER RAILWAY Regards Garry
