SNIP Sorry for the small size, which I will try to correct. (I'm struggling a bit with settings on a new Flicker account.) SNIP When I post a picture from Flickr, I select the 'medium 640 x 480' option before copying the link.

ibb.co/LZNb30FAnd here she is all superbly in mostly timber. The dome and Chimney I suspect are castings but 3 years to build. ibb.co/f0W65V4Not made by me but as part of my collection a superb Asia Crank axle. Toying with the idea of mounting it for display and making another. David, and Lily who would have to have it in the house and polish it.

ibb.co/yVzYVFSHere is today's offering and yes the blob on the right is the broken tap forever holding the parts together. Blow the expense he said as he gains another PLUG TAP in 4 BA. It is very strong in itself but the extra holding power gives more confidence, after all it is not a race to finish as most tracks are very firmly SHUT!!! ibb.co/jf1x7qNShows what they look like when cut off and filed over. The countersink is done at 60 degrees with a centre drill. The bolt is done with a round nosed tool and well tightened in. Six per bracket. The little extension was tested to destruction so gained 2 threaded in once I had re glued it in place. That showed me. David and Lily. Should the broken tap incident go in the joke section?

Today I had that Victor Meldrew moment with the second motion bracket? YES overnight the inner plate gets stuck in place within a little squeeze from the vice and sets at 2 1/4" Drill 2 holes. CAREFULLY tap them out one is perfect and soooo bang and the same position hole as the other breaks.
I decide to have a Break from the bits and go on to putting a backplate onto a spare slim 4 jaw for the Myford. Getting on well but hit some hardened pegs. Can I find my toolpost grinder. Well at least I can unscrew the plate it is mounted on and use the other chuck. Just trying to save myself swapping the jaws round and completing a job that has taken so very long.
David and Lily.

ibb.co/Gkv0J52Here is some progress done just before we hit the Rainy Season. I have abandoned Halfords paint except for the filler primer as it sticks on well. Instead its Paint Services. Well their shop is walking distance from the house and they sell this stuff called cellulose. I got Lily to choose a nice green and can't wait to start applying. Currently reading with interest the 1501 saga discussing paint, grit blasting and painting Rogers model. I still have lots to make and fit onto the frames before painting in the flat and bolting together. David and Lily.

ibb.co/zZ1Ct1BShows Kens Bridget with the oiling system which looks very interesting. One shot in a box and you are fine for the day! Ken had some wonderful ideas on his Locomotive Designs including having very correct and well presented drawings. His rocking grates are a delight to use apparently and you can literally Drop Your Fire anywhere. It goes into the ashpan not on the track!!! Well most of it. David and Lily.

Progress from earlier in the week with milling out the big end bearing and polishing. ibb.co/NWMgCHXBig end almost done. It is surprising just how useful Lidl small drum sanders have become since I bought lots of them. Also a Warco high speed grinder to use them in. David and Lily.

ibb.co/rMKKNctAnd Jeof Theasby mentioning our front cover Photo on the Reading Club Magazine gets us once again in Model Engineer. Page 51. Dearest Lily arranged the pieces in the house and I just did the photo. We have been on 2 front covers so far this year. Of course it is Jessie Related. There was quite a bag of Swarf once I had finished. The brass top was heat fitted on. Will come loose if she is worked hard!!! David and Lily.

ibb.co/Vqtm3r2And on its own looking great. ibb.co/WBgST8kAnd what a lovely way to assemble built up sections for us without heating up facilities. No distortion and all hidden screws (and broken taps) hidden from view. Filed or filled! David and Lily.

ibb.co/M9JD1ZrPlodding on with the many little bits that go to make the whole! Yes a bit too thick but today milled them down to 6.80. Lots of polishing but they are again something that everyone will see and any blemishes noted. The extension makes them more balanced while turning on the Lathe. Next operation is to drill and tap for the securing bolt in the bottoms. Then a careful slot. David and Lily.

The day began with creating a very accurate spacer and alignment thing. ibb.co/Q6SHRFWA tight sliding fit into 3/8 reamed holes. I jumped onto the Emco as it is superb at this. The Myford is superb at powering off metal and stop start for fitting things. ibb.co/vXCDWzmNext comes the 2 holes for 5BA machine screws held in the fitting. Tap one, open out the hole... Bolt and do the other. ibb.co/DCYK1nLMake yet another size of filing buttons on the Myford and get filing. Part way through, the heat finally gets into the workshop. ibb.co/9whLyysLooks very nice showing the spacer. Bit of artistic licence by making the diameter out to 18 mm so that the boss gets to keep the nice radius. Also cheating by a slight overhang so that any slight out of square is hidden. This is a very visible part and will be kept polished. Then of course make another to match!!! ibb.co/443k5P0The TWINS Cruel that they are side by side for checking! Remembering that I filed all the edges with an aversion to letting a cutter catch on the last side of the day. David and Lily.

ibb.co/0VjTBd3I have had this Big brass flangeplate for years, Today it got roughly cut then machined for the Exhaust pipe flanges. These on the drawing are slimmer but as I have all this meat I thought I would use it. Soon Done it was on to a quick file from a new file. I aimed for a tight fit to aid drilling for 4BA. ibb.co/681YQb0And an alternative vice. Next comes marking them TL and TR. ibb.co/d6JGQ58A nice bit of card stuck on and the Cylinders attached once the holes had been punched. Spot through and remove the flange pieces. Drill the Tapping sizes 3mm. ibb.co/GtMxHHwBreak into the exhaust passages and remove the Cylinders. Pop the Flanges back and mark where the holes line up. These seem to be important! David and Lily.

ibb.co/547XC1WIs the front solution I came up with for the anti tip/plunge off the track arrangement. Lily assists superbly holding it and avoids a clamp. As they are on the outside we can take advantage of using 3 holes! The angle is on the inside. The rear is the same only shorter using 2 holes. I am doing them now so that it is all easy to get at. I will have to cut the rear angle down in 2 places to avoid the Brakes... One of the reasons for having them in the first place! Typical. David and Lily.

ibb.co/DLbcMnDIs the result of Tuesday with a bending jig and the first two guard irons. With of course two more in the Pipeline. Just so easy and ensures they all come out the same. I milled the curve and then cut down the taper. It could do with a bit more to be in line with the drawing but I think chunky looks good. I shall leave the more Delicate ones to the 5 inch Locos. ibb.co/cvX2r3pIs a close up and a lovely trick I thought up is to screw the bolts into tapped holes so when painted they remain perfect. Pop through the holes and tighten the nuts. Then a visit to the track bung on the Heavy Duty pair. David and Lily.

Hi David, Yep nothing wrong with heavy guard irons, especially when some little .... puts rocks on the track around a blind corner, or worse in the tunnel!
Cheers Kerrin

Cheers Kerrin Better still clamp a bar across the two tips (about ½" or 7/16" dia), and have it protrude either side beyond the cylinder draincocks. The first time you derail you will bless this bar, and without it you will slice the draincocks off at their roots. Painted black, the bar is surprisingly discreet- I've never had anybody comment, which means they haven't noticed it. Gary

Hi Gary, They work great! Maybe David could incorporate the bar into his pair used when running. The other thing that helps with is, if/when you derail it’s easier to get some form of lifting gear in there to do the job.
My dad didn’t have lifting gear in his ride trolley, until after he had the loco slice about 3/16” off the end of his thumb!!! Mind you he probably wouldn’t of done that if he had asked for / waited for help!
Cheers Kerrin

Mind you he probably wouldn’t of done that if he had asked for / waited for help! Cheers Kerrin The first crash bar I made (for a 5" Speedy) did in fact clamp on to the Guard Irons, and was fully removable. (That was after the third draincock replacement!) But I soon realised that the only good reason to remove it was for a glass case or an exhibition. Bridget/Jessie has exactly the same vulnerability and exactly the same cure, except this time I brazed the bar to the Guard Irons. Then I started building a Paddington and did the same thing, but made the bar ½" dia in deference to the extra weight.... for an exhibit I could quickly replace the device with scale Guard Irons, but I can't see it arising. Lifting gear for a Bridget? Nah. You only lift one end at a time to get her back on the rails, she's a featherweight amongst 7 ¼" gauge locos. Paddington not so much... -Gary
