The chassis and body of Locomotion's tender are made of English Ash with everything held together with little mortice and tenon joints, then held tight with long square headed tie rods (4 BA). The axleboxes fit into plummer block type castings which are bolted to the outer chassis longitudinals. I used 4 BA Allen cap screws, with the heads hidden under short wood dowels.I suppose I didn't have to, but when I assembled the chassis finally about 6 months ago I also used a good quality waterproof wood glue in the joints. The chassis, without the body sides, was then set on one side while I did other, non Locomotion type things, such as gardening. When I picked it up again a couple of weeks ago, I noticed that the axles didn't seem quite square across the chassis. Indeed, they were not, a matter of about 1/16" in 6" (its 7 1/4" gauge). When I finally glued up the chassis, using woodworkers clamps, I can't have paid enough attention to checking the final squareness. Grr! I toyed with the idea of just letting it go, it wasn't a huge discrepancy for a 2 axle tender, but my better self (who doesn't pay me many visits I'm afraid) wouldn't let me. So, its been a case of removing both plummer blocks on one side, drilling out the bolt holes 6mm and glueing wooden dowels into the holes. After that had set for 48 hours, I then reset the plummer blocks in the correct position so the axles were parallel to each other and square across the chassis, clamped them up, and drilled the bolt holes through the side rails. The axles are now square across the chassis, and parallel with each other within 0.002" Its a good job that I hadn't fitted the wheels to the axles, this rectification exercise would have been more difficult with them in the way. Anyway, wheel fitting is next, followed by fitting the tender sides and rear, and mounting the tank, which perches above the body sides. The tank baseplate has brass angles underneath which bolt to the tops rails of the body sides. More tie rods (theres 38 in all) fasten it all together. The tank has a 3mm bottom plate and plays an important part in stiffening the tender framework. The whole thing is surprisingly heavy even without any water or coal. All these bits (except for 24 short tie rods) have been made, so final assembly shouldn't take too long now. Then it will be a visit to the track to make sure it rolls through the points and crossings without coming to grief. The woodwork is Ronseal medium oak satin stain, and the tank, wheels and other bits of ironmongery are satin black over an etch primer, which seems to have taken quite nicely, and look the part. As far as is known, in service there was no lettering, lining or crests, so thats a task saved. Then it can reside in state on a shelf in my study for about 4 years till the loco catches up with it.

I do appreciate those who have done model engineering today. Quite inspiring! My day started with roding the blocked drains, a s****** job. Back to the milling or should that be smiling!!! D DIY for me David... has been for the last week... the bathroom is nearly there, the hall still looks a mess.... waiting for my son to phone his plasterer... Pete

What I've done today is to stop doing anything! I just seemed to keep dropping things today, and only about a 50% recovery rate even of things I thought I'd seen where they dropped. Give it a rest now, see if I'm better tomorrow.

Today I went steaming at the Yeovil track, really did well right up to the point my leading truck lost a wheel. This wheel dropped into the track and derailed the rest of the locomotive, tearing springs off hornblocks, chipping a driving wheel flange and thrashing the underside of the ashpan. I burned myself a bit lunging to keep it upright on the track (nothing major), but managed to stop it becoming a bigger disaster. As a result my battered and bruised locomotive is now on its side on a big blanket (my Britannia is hogging the spit) while I assess the damage. It had been running well (I'd just refilled the lubricator for the third time, used an entire lunchbox of coal and the ash was halfway up the smokebox door) so its a shame, but all I can do is repair, improve and learn from it. Not sure how I would have forseen the wheel coming off however, they have never given any real issues in the past!
I need to fully inspect and check for any further damage; hopefully what I have listed is the worst of it. Enough to keep me busy for a few weeks...
Bruised but not defeated.

Ouch indeed... glad that you're not badly hurt but that could have been a lot worse.
Did the wheel lose its interference fit on the axle or was it held on with Loctite?
Regards,
Dan

How frustrating Jon. You were getting well on top of it too.
I've been laid up for a couple of days, having taken a tumble and jarred my knee.
I did manage this morning to clean and polish the Polly 1 ready for the new owner who is due to pick it up on Monday.
As the weather was OK today I was planning to push the mileage up on my bike. It was not to be.
Always another day!
Pete.

Regards, Dan I cant see any evidence of loctite, but the wheel now spins freely. I suppose its possible something had jammed the axle but its unlikely, there doesn't seem to be any marking on the wheel thats still connected to the axle. I would have expected some sign of skidding (and hopefully noticed it from where I was!)

JonL I had a set of wheels solidly on axles that I carefully began cleaning up far more than had been done. Did the first pair and was just moving off for Lunchtime Nibbles and the wheel rotated in my hand. Oh the struggles to get to the inside. They then all came off just a bit of rust holding them on.
Yesterday we had our AGM.
Did more bricks for the front. Went to Berkshire metals on a 2.6 mile round drive. We have walked.

I would have expected some sign of skidding (and hopefully noticed it from where I was!) It could have been a marginal interference fit and the effects of a fixed axle caused it to be the weak point in the wheelset w.r.t. self steering. Remember one wheel will always want to rotate faster than the other around curves. One of the Brit's tender wheels was loose on its axle when I started stripping it all down. Better check all the others while you've got it apart for repairs. Regards, Dan

Not done any model engineering for a while. The latest project has been setting up the garage/workshop. It’s been 3 yrs since we emigrated to NZ, now in our own place with a 12m x 7.2m man cave. It sounded like we may have been heading into another lockdown here in Northland so after work I did some panic buying and got 56m of 4” x 2” timber to do the partition wall between the two halves just in case! TomorrowI should get the stud wall finished and then it will be time to start getting the workshop layout finalised.

Today was the East Grinstead Model Engineers steam up at a member's private track.
A lovely morning spent watching, chatting and driving a few laps on the club Maid of Kent.
A great way to spend a few hours before leaving early for family business!

Did an unload of yesterdays metal some of it nicely cut. Try and fit 4 meters in the car or walk 1.3 miles with it!
I got the hand held rev counter set up and working... Next job during the quiet of a Monday is to try the mowing machine motor and the E Beast for their revs at the crusing setting, so we can get a better top speed this time. Yes E Beast has an unknown top speed. Someone once hinted "Don't hold up the others on the track with THAT!!!" They kept quiet after I set a new track record for the Straight. So needing a pair of W. Heath-Robinson name plates for it/her.
Then it was back to insulating and adding bricks to the front. The step ladder has come in to help the high bricks so we are almost back in the workshop. The Weather Radar was visited 4 times today and it still rained during our Evening meal.

On my weekly Sunday visit to the club I borrow a bound volume of 'Model Engineer'. I'm up to 1965 this week and a February edition makes reference to Churchill's state funeral and draws parallels with Nelson's funeral in 1806. From what I can gather one was pickled in brandy after death and one was pickled in brandy before death. Too much time reading old magazines and not enough time doing anything practical I hear you say. Guy

Brandy to cope with what was going on at Churchill's finest hour!!!
Outside and missing 2 rain patches by several miles Abingdon and Bracknell getting them instead! I got to the top on one side of the front window with bricks. These are cleaned up and flap wheeled to get some nice colours. Tiles to be added later when I get to the top of the other side.
So missing the workshop but the house is getting warmer without going down and sitting on the M 25!!!!!!!

Not often we get a celebrity knocking on our door....
Answered the door yesterday to a lady with a parcel for my wife. I thought she looked familiar. It was Jodie Neale, the local lady who won the 2021 Great Pottery Throwdown on TV. My wife knows her because they are both keen cyclists and did a girls' cycling holiday in Majorca a few years back. Anyway, it was a pot, and I have to say, I have a new appreciation for such things. It is bloody magnificent to be honest.
As we see on here, there are some very creative people about, making things that take your breath away.
Pete.

As we see on here, there are some very creative people about, making things that take your breath away. Pete. I've an appreciation for anyone making things themselves with learned skills rather than putting money in Amazon's pockets. I used to routinely make candles and soap (from scratch, traditional methods) which I'd use round the home and give as gifts. Until the family begged me to stop.... Not as skilled as pottery (something I'd love to try) but interesting all the same. For my second date with my now wife I took her to a marble sculpture workshop where we both made an apple from Italian marble. At the end the instructor looked at my wife's lovely looking organic apple, and mine that looked like a mummified toilet roll, and said "are you an engineer by any chance?"

Did you watch the TV series? She is such a modest person but with the most incredible vision and gift for creating the vision. I've designed and created many things, all 100% functional, but no-one would ever want to stand and admire them. Pete.

You are guilty of the same thing as me; comparing your work to the watchmaking artistry going on elsewhere on this site and thinking it somehow devalues your efforts! We are making locomotives; something I never thought I'd be able to do, and every tiny sliver of metal cut is a bit more learned. As for the TV show, sadly I don't have a TV connection at home; we have netflix for the odd film but for the most part I don't see much else.
