Those look great Dave, well done.. one question, I can't see an oilway for the knuckle joint? might be a good idea to do one even if not on the drawings? And yes, using MEL blanks saves an awful lot of time... Kind regards Pete

Hi Pete
I didn't bother as there is a little Glacier DU bush in there, I find the oil gets into the little joint in the bush ok. I've used DU bushes in the valve gear of a couple of locos and they show no wear at all. I do drill oil holes for the ones that move about a lot, but these should only waggle up and down a bit, thats the theory anyway! Dave

My 3.5” gauge A3, Hyperion, had some annoying paint defects on the tender which I couldn’t colour match, so I masked it up and re-sprayed the tender. Bit of a back to front way of painting an engine, but the green is also a better colour. I will probably do the rear and near side as well. Tim

Went to the visitor's day at the Surrey Society yesterday. Had the pleasure of meeting David Scott and other people I have met at previous events. So good to be able to resume these activities. Have to say it was a very pleasant event, hospitality and help was outstanding, and a nice running track too. Apart from one shower the weather was very good too. Pete. Yes a superb day and carefully calculated to the MILE? YES and upon return had 15 miles of Petrol left. That was close as we passed Reading Services who were OUT of FUEL. Something they are never supposed to do? Tom Parham and I both had problems with the track. We fly round Reading, but the third set of points and we came off. I borrowed some spanners 13 and 17 mm and altered the guard bars. Bliss then fell out with the signalman as it was my first time round and I was heading for the EMPTY raised track. If you like Signals this is the track for you. Then we fell off the raised. Helped back on with no damage. We hit an OUT OF SCALE TWIG. Toms coach came off as I was doing a second circuit as the turntable line was occupied. My driving truck has lots of built in flexibility with rubber washers and Nylocks on everything. We hid under the trees during the SHOWER. I having done a mad dash for coats. It had been so very hot. Too soon we cleared up and had a last chat to more of our BIG FAMILY. David and Lily. Tom Parham organised this years IMLEC. Sue Parham drives Jack for hours having carried him in a bag. Martin Parham won the Award with his 2889 at our FMES at Reading last month. Federation of Model Engineering Societies.

Actually a few days ago, but I’ve only just received the photo below from my mate today..... We attended the GCR Gala on the Thursday and had some trips behind our old 9F friend 92214, that we spent so many years working on during its restoration, plus the visiting 92134 from the NYMR. Thanks to two of the GCR staff that we knew, we had a tour round the shed and it was great to see the “real” smokebox numberplate from 92214 that has recently come to light and has been “donated” to the engine (the one it currently carries is a replica). The original is still in the condition that it was in when removed from the engine back in the 60’s, even still has its countersunk bolts! Good day out. Cheers Don

Dave Great idea, did not think about that. I may do the same on mine, should be just a case of open the hole out.

Dave I'm afraid I can't claim credit for it, the late jim Ewins gave a talk at our club about his 9F "Lode Star" which had lots of innovations, one of them being DU bushes in the axleboxes and motion. I used them in my Simplex which is now very worn, but the DU bushes are still fine, interestingly any bearings of drawn bronze have not worn well at all, the cast gunmetal ones have fared better. The oilite bushes I used for axleboxes are totally knackered, the rears have filled with ash that has acted as grinding paste. Oilite turned out to be a poor choice, but at the time I was working to a very tight budget, small children seem to always need new shoes!. The DU bushes having a thin wall can be fitted in quite easily, a 3/16" bush is only 1/4" od. One of my very few career highs was when I suggested fitting DU bushes in the heavy electrical switchgear we reconditioned instead of boring out the cast iron and fitting non standard oversize pins. Turned out to be ideal and was fitted in new switchgear as well, company saved a fortune and I got a "prize" of £50, and the works manager stopped looking at me with distain! I suppose I should have shared the £50 with Jim. Dave

Do you realise there are 3 Aspinalls being built by 3 Dave's, You, me and Mr Goyder (Midland).

Dave Great idea, did not think about that. I may do the same on mine, should be just a case of open the hole out. Dave These are what I will be using on Calbourne, although I am using the "DX" version instead and "DU/DX" thrust washers at the shaft shoulders. The DX versions require a little oil whereas the DU are PTFE-lined and require no lubrication. The DX are also able to carry a heavier load but I don't know if they will be good enough till I have a running chassis.
Regards, Steve

Not really what I did today, I cut out the centre segments of the crank axle this afternoon, I made it a few days ago and thought I'd let the loctite set off for a bit, never made a crank axle before, I quite enjoyed it, the webs are laser cut by MEL and just needed a clean up and boring for the axle and pins. There is a deliberate mistake, in all the exitement of loctiting it together I've got the lead wrong. The left hand side will lead instead of the right, I so carefully marked it all up and still got it wrong!
Bought down to earth with a bump today, I was hoping to have a rolling chassis fairly soon, was aiming for the end of the month, until Mrs Woo reminded me I've got two weeks jury service to do in October. I may attend dressed as Napoleon and hope they send me home, do these people not realise there are locomotives to be built. looking at the picture I see I caught the inside of one of the webs with the hacksaw ,Doh!...

After reading the comments on the speedometer thread i have now bought one of the types recommended, it will be put aside for a while until I'm back onto the tender for the final bits and painting/lining. I have also finally got around to buying myself a set of riffler needle files, they are only a cheap set but I have tested them and they will do the job in hand which is basically to finally get around to the final filing/polish of the coupling/connecting rods, these will finish the flute radius nicely. I have already done a little work on the R/H connecting rod and I'm happy.... One day I'll get myself a decent set but boy do they cost. Pete

I hear what you're saying chaps but can't afford the top stuff..sure I saw some with a £200 price tag for only 1 file? These weren't the cheapest but certainly cheaper than some mid price stuff which IIRC cost £27 each. The good thing about this set is I can work out which shape works best and perhaps get a good file of the best shape later. These aren't bad though and should last long enough to do the motion even if they are made from tougher material than mild steel. The test I did was very satisfactory... Pete
