I've almost completed drilling the frame plates.... I've just got a 1/2" hole to open out to clearance for the brake shaft in the driver's side plate, and then a set of holes under the cylinder for a stretcher. I only discovered on my last visit that this stretcher is no longer fitted, and after drawing up the center coupler that its currently fitted with it became evident why, the two foul each other! Whilest Penrhyn may not have been bothered about loosing the strength of the stretcher, I am, so I've opted for moving it backwards enough to clear the coupling, but obviously I'll need to mark and drill new holes as they weren't spotted y the laser in the new place. Sadly, work may very soon grind to a halt. My wife's employer has announce 1700 redundancies and she's in danger. As she's already spent 4 years looking for a job with no luck, we're rather worried to say the least. If it happens it'll be just after Christmas, and I will have to cease all expenditure on the workshop and the engines. I won't be giving up on it, but when I'll be able to finish the workshop and get on with the engine will be anyone's guess.

Had a bit of a push just before Christmas and got a few bits done. Can't claim credit for all the work, one of the millers was short again so he's done a little milling for me. With everything going on I took the photo's but didn't have time to upload them and post an update, but now Christmas is out the way I've some free time....I'm sure Matt's having picture withdrawals.... The brake shaft bearings are now finished, holes drilled and flats milled, although it looks like I actually haven't photographed them, and they're still at work...must try harder... I have rough milled the brake hangers and I stressed relieved them while at work between Christmas and new year.... Studying photo's this morning while designing the missing stretcher, looks like I slipped up somewhere....For some reason I designed the hangers (Matt - they are pivoted at the top, hold the brake block in the middle in line with the wheel, and have the pull rods pivoted on the bottom ) with a boss on both sides top and bottom....looking at the photo's this morning its only one side.... No idea how that happened, but no problem, I'll use the extra material to hold it while I finish mill them, and then machine it away. That probably means the pivots are too long as well, but again, I can just put them back in the lathe and part off the extra length. No idea what happened there! Not doing very well here...the other job was the machining of the forks for the brake linkage....turns out I haven't photographed them either...and they're at work too....!!! I have photographed the embryo drop links for the brake shaft, although it was only after machining them I relaised I'd slipped up....only needed 1..the drivers side has a double arm for the hand brake screw as well! These need some milling attention now, turn them in to a pear drop shape. Slightly out of sequence, but this morning I silver soldered the bolting pad to the steam brake cylinder.... The main update I'll do a separate post for just in case...give me a minute!

So, the main excitement for Christmas week...are you ready for this (Matt ! ) ...... Ta da! I'm a happy chappy to say the least, there's a few things I'm not 100% ok with, but nothing that's going to make me take it apart again. I've started a notebook to keep a list of things to modify, before I think about publishing the design. Not much, just reducing rivet sizes on the strecthers, tweaking the pitch away from corners a little. Few detail shots.... Fitted bolts for the stretcher just in front of the firebox... Underneath... Guide angles for the Penrhyn buffer/coupler.... Front... Rear... Yes they are different...typical Quarry engine Stretcher under the cylinder...the first bit I finished, only to discover its no longer fitted to the engine! Horn keeps... (nothing to do with music Matt, strengthens the bottom of the frame and stops the axle falling out if it's lifted ) General inside shot... Today I've progressed the drawing for another stretcher that fits behind the smoke-box and cylinders. There's a lot of flex in the frames at the moment I'm a bit worried about, well, perhaps that's too harsh, I'm hoping this one stretcher alone will make a big difference, its a beefy affair. Will look for some material next week and then I can start fabricating. I think it'll be a case of (Aubyn) weld and some silver soldering..not sure yet. Casting would be best, but it's a complex pattern and I don't think justifies the expense...The pattern making is beyond my abilities. What else is there...umm.. Currently thinking of getting that stretcher fitted, finished and bend the outside motion brackets and fit them, two angles on the rear buffer beam that need riveting on, finish the (dummy) riveting on the front buffer beam and then taking it to Coventry and have it media blasted and then primed. I can't blast it it's too big, and getting at least a coat of primer on will keep the rust at bay. Wouldn't mind starting work on the horn castings too, some of the milling I can do on mine, but the holes and finishing will need doing on a machine with a DRO if not NC. I also need to get the replacement fly-crank milled to shape, I've turned it and bored it, and cut the excess material away, just the crank-pin hole and profiling need. On Holly's job front, we've no news Nothing has been said either way so we're still in limbo a bit. 2013 was a dreadful year for us, all the way up to the death of a friend suddenly on Christmas Eve. We've got 3 very ill friends and family starting 2014 so it's not peachy, but the year has started well, Holly's got an interview on Friday...we hope it's a good sign!

That looks brilliant Ed... you've been a busy man... I hadn't appreciated how big it was until I looked at the last picture and realised that the tiny electric drill is in fact a normal sized one... that thing is massive... Great work Ed I look forward to the next update.. oh and fingers crossed for Holly's job interview.... all the best for 2014. Kind regards Pete

Hello there, "Mr Parrot"---------Strewth !! You HAVE been busy....I particularly appreciate your use of the slotted table for accurate assembly, nice touch that......'tis a tad B-I-G, eh ??....Are you planning to do some contract freight haulage for EWS ?? LoL !!...........

Whats worrying is that the Pics Ed has taken really dont do the frames justice when your up close to them.

hi ed, excellent thorough and prototypical work of which you should be very proud! i do like the fitted bolts! nothing like following the odd details of fullsize to give that extra bit of satisfaction! BTW anyone found any clips on youtube of JUBILEE working? ive got plenty of Ivo Peters stuff of the quarries at Penrhyn and Dinorwic, but none show JUBILEE. cheers, julian

Thanks guys, its a great feeling to have these together I've failed Julian...very little to be found actually. I think I've found one dreadful photo of her in a shed, and there's the (in)famous photo of the Coed Y Parc scrap line in about 1955 which shows her and Lilla, think Eigiau is there too, can't remember the rest. I'd be very interested in ANY material anyone has on Jubilee, though I'd rather this thread concentrated on the model

Missing photo's... The brake adjuster forks.... and the finished brake shaft bearings....although, I think an oil hole in the top might be a good idea....

I've been busy doing odd little bits when I can, not a lot of time in the week and being doing a bit at the club recently. Not a priority at the moment, but I made a start on the brackets that go inside the buffer beams, and take the strain from the couplings. 4"x2" steel channel is just a touch over size for scale helpfully, so I'm using that for the basic shape. The mill table was clear so I've started by milling the legs flat and parallel to the back.... I then started work on the missing stretcher which sits behind the smokebox, and I think this will make a huge improvement to the strength and rigidity of the chassis. First up was machining some 10mm plate down to 5/16"....Its great being able to do this again! Aubyn then applied the big welding torch for me and added a piece of 32x20 bar to one side, and I cut the material to make the ends and side.... Following which Aubyn applied the big welding torch again and produced what is currently I biggest fabrication on the end! Quite a lot of this will disappear during machining, but I've had to do it this way mostly because of holding it for future machining ops - always plan the job out complete! I'm hoping to get in the workshop tonight to start on it but we'll see. I then popped an angle plate on the table and machinined off the ends of the outside motion brackets. The angles were welded to this quite some time ago but I'd not got round to machining them properly, a Senior M type mill proving to be nowhere rigid enough. These can now have the (dummy) rivets put in, the bolt holes drilled, the bend out in and be bolted to the frames.... Finally, I've also machined the bolting pad flat on the steam brake cylinder....this can be set aside now until I can set out the bolt holes...

nice job there ...
a silly question .. how are you going to go about putting the 6.5deg bend in the motion bracket .. or are you mounting the whole bracket at the required angle?
its one of the jobs I have coming up on my loco in a few weeks..

very nice Ed... looks like your loco is going to be a heavy bugger.. better start eating well in preparation for adding more bits to the frames.. Pete
