What About The Bee

There is a bridge which is quite famous for being struck. 11'8" posted clearance. There are automatic sensors, with stop lights, informational signs & etc. It has everything needed to prevent a strike. It was struck so many times, the railway raised the bridge by 8" to 12' 4", at enormous cost. Didn't work. Still being struck. The proof? 178 videos, most of which are the bridge being struck. Not the aftermath, the actual strike. There are a handful of videos wherein there is discussion. https://youtube.com/@11foot8plus8 Bee

Delta solution 1 v 2 14'6" - 14'3" = 3" OO Scaling 3" / 76.2 = .03937" Convert to metric .03937 × 25.4 = 1 mm The difference between solution 1 and 2, in OO, is 1 mm. The height is measured from the crown of the road in the US. Perlouit95 must therefore also control the surface of the road, including its crown, relative to the underside of the bridge, including its arch. To 1 mm. ~~~~ Hi Perlouit 👋 Unless you are 3D printing the bridge and the road as one unit, it will be difficult to control all of the dimensions precisely. If your bridge is slightly off compared to the real world, the only one to notice will be you! When you consider the OO squish (for the non scale track) a minor height error becomes insignificant. I understand striving for perfection. But I also understand providing tolerance for components. If this were me, I would easily accept plus or minus 1 mm for the bridge clearance. Bee

Hi Three Link When I suggested "rubber cement" to Wapples, my greatest concern was naming. Rubber cement in the US apparently is "contact adhesive" in the UK. But Wapples is in Australia! Very likely there is yet another name for the same product. Bee

If you want an instant bond, try rubber cement. You paint a layer on both surfaces and let dry. Then, touch the surfaces together. Instant bond as they touch. A couple of warnings: 1. It isn't terribly strong. 2. NOT permanent. Use another glue elsewhere on the part to achieve permanence. Think of it as an invisible clamp to hold an item in place, while the other glue sets. 3. No adjustments after the parts touch. Its a one and done. If you do not like the position, you will need to separate the surfaces and try again. Fortunately, see warning #1 4. It may peel off the surface it is painted on. It doesn't stick to everything. But it is the only glue that I know that instantly bonds. Everything else has a set and cure time. For rubber cement, that all occurs BEFORE the parts are in contact. Bee

Hello Big Cheese Do yourself a favor and google "fusion 360 paywall issue". The sense I get is that they can lock up your models behind their paywall, if they arbitrarily deem you to not be a "hobbyist". There are plenty of complaints online about this. That cannot happen with FreeCAD, as everything resides on your computer and you absolutely control all your files. I originally wanted Fusion 360 but had some issues. When I did some poking around to find the solution, I encountered chatter about the paywall issue. I was done. Bye Bye Fusion 360. I intend to invest quite a bit of time in my models and I am not going to be held for ransom Bee

Hi Rana Quick note on the 32 bit. That would be version 0.18 which is available at Github, and the version I am using. https://github.com/FreeCAD/FreeCAD/releases/tag/0.18.3 The tool at this level has been adequate to get OO Planet underway. I have yet to encounter an issue that prevents development. OO Planet Update I've broken through the Gordian Knot of the gear train, valve gear motion bits and motor arrangement. It must all fit in to a OO Planet shell and not interfere with itself. I have just finished installing the eccentric rods and the eccentrics into the gear train. The eccentric sheaves will be along shortly; with the motion on the front of the smokebox afterwards. My goodness I was chasing my tail, but the epiphany came yesterday. A bunch of hours of FreeCAD jockeying and a solution forward was proven. Wow that was tricky! Bee

The Lacey & Allen Carriage may be seen at 2:35 of the video. It appears in a well known image, created by Issac Shaw. Shaw is a known good observer. He understands proper perspective and did draw the things he saw. Two very unusual carriages are illustrated in this one image. The front of the Lacey & Allen carriage is illustrated, showing detail no other artist does. The Carriage is being turned on a turntable, by manpower. It simply would not do to ride backwards. The Lacey & Allen also appears in a few other images, I have described this earlier. The best image of the Chinese Liverpool carriage we have also appears here. It shows the pagoda roof and the strange kickouts on the sides of the carriage. From this image, we can see they were of shallow depth, unlike other depictions. Bee

Hi LT&SR_NSE Thank you for drawing my attention to the awkward nature of the formatting. It should be corrected. Hi Yelrow I appear to be too dense to pick up on your clue. Thank you for trying! Bee

Extra points if you can spot the Lacey & Allen carriage Yelrow! Bee

The government has granted Scheduled Status to Edge Hill Station and cutting for the LMR (LPMRW!). This was the location of the famed Moorish Arch, which housed the winding engines for the Wapping and Crown Street tunnels. Scheduled status is granted to archeological sites meaning it cannot be disturbed without government permission. To which I say Hooray!! The video is filled with wonderful imagery and is well narrated. Some of the images date from the earliest days and I do recognize them and the artist. Others are photographs from more modern times, which I am completely unfamiliar with. Track plans, etc! This is well worth a look. Recommended for all railway enthusiasts. Bee EDIT: White text is a new one on me!? How strange, I use my phone to post which is typically white text black screen as it is easier on the eyes. First time for this. My apologies

Always such good videos Alberto! Bee

Hi JJ Now your selection makes even more sense JJ. You already had some Bassett Lowke Steampunk and decided to add some more. I did enjoy your review. I do hope you got rid of that bump on your test track. That bump will damage your Hornby kit. I had no idea the locomotives were die cast! Bee

2. Attractions, Events and Experiences This is fine for UK consumers, but what of EU and ROW? There is one experience I see discussed here in the forum which I would like to experience, but cannot: TV programs. I see the lads discussing the programs, but alas, they are out of reach for EU & ROW. Perhaps offer a CD of the past season, but only can be purchased with points! Bee

Types of rewards, beyond points and discounts, that would feel like a real coup Hornby website prices are in general higher than the exact same item at a stockist. The rationale is that a consumer's item is guaranteed from Hornby, not from the stockist. The rationale is that your price at Hornby is guaranteed for a pre-order, not at a stockist. The inducement to order from Hornby, even at a higher price, is surety of getting the item at the price you ordered it for. FOMO [fear of missing out] drives sales to Hornby. Points may reduce the price of an item to below that of a stockist, but it may not. If you want the rewards program to feel extraordinary to a consumer, combine the two concepts. Guaranteed item, at a price BELOW what I can expect to get it for at a stockist, but only when I pay for it, or pre-order it, with points. Surely Hornby have an idea what discounts stockists give. Exceed that discount, but only when you pay in points. Bee

Hi Three Link Material between glass sheets should be flat and of uniform thickness. Felt would do. Cardboard would as well. Anything that could apply point loads would be rejected, as localized bending and stress concentrations could be created. Even a sheet of paper of requisite size. I searched for images of your Coral A wagon and there are plenty. One lad did a fantastic job with his model, the wooden crate is loaded. Chains a touch overscale, but acceptable. I also note that "DAZ" has some 3D printed models of Coral A. Some cracking ideas there. Bee

Thank you LT&SR_NSE! That is very well put. I do not like everything in the Hornby range but I can certainly understand if someone likes a model I do not. The world certainly does NOT revolve around my preferences. A perfect example is modern era. Anything diesel or electric holds less than zero interest for me. But are there enthusiasts? Yes sir, there are. I respect that and wish them all the best. Hi JJ. I hope you enjoy your Bassett Lowke models and I do look forward to your review of them! Have fun JJ!! Bee

The oldest person ever whose age has been independently verified is Jeanne Calment (1875–1997) of France, who lived to the age of 122 years and 164 days. If Frank Hornby was alive today, he would break that record by 37 years, 201 days. Not very likely. Happy Birthday Frank. Bee

Hi Three Link There is plenty of information on shipping and transporting sheet glass. Perhaps not in Coral wagons... Glass is shipped standing on edge, never laying down. The box is lifted from the top, and usually not from the bottom. There would be separation packing layers betwixt the sheets. This is all related to Beam Theory! A thin beam will deform more readily than a thick beam, as the deflection goes by the height of the beam cubed, in the denominator. Once accepted, a sheet of glass on edge has a tremendous beam height, a sheet of glass laid flat has little beam height. Next, consider how yield strength and ultimate tensile strength affect this. The material bends, until deformation occurs at yield. When the material bends beyond ultimate, it shatters. Materials that have yield and ultimate tensile strength at nearly the same values are brittle. That is glass! Putting this together, glass deforms under load. The deformation goes by the height of the beam. Orient the glass to maximize beam height to minimize deformation. Minimizing deformation of a brittle material reduces breakages. Separation of sheets reduces scratching. This will have been very well known to glass factories, for the period you describe. Bee

David We will not know until you perform the measurement. It is very possible that the motor got hot without melting insulation. Bee

To clarify my concept. Look at the Bassett Lowke locomotives in the Outlet Shop. They continue to languish, even at ½ price. Suppose there was a Move it, Move it sticker offering an additional 200 reward points. Would that be enough? How about 500 reward points? Maybe 1000 reward points will work. Various tiers, with the objective to move a slow item. This benefits both Hornby AND the consumer. Hornby makes a sale of an unpopular item, and induces a sale of a future item. The consumer gets a Bassett Lowke loco (to continue the example) at a discount and a few points towards a future sale. Now that is a win win. Bee

Hi David Understanding WHY is always a good thing. 96RAF wants you to measure the ohms of resistance for each coil of the motor. Why? An electric motor produces magnetic energy by the number of windings and density of those windings. To obtain maximum power, a motor manufacturer will make the coils with wire dipped in insulation. This allows the wire to be packed closer together, producing more magnetic energy. When you measure the resistance of each coil, you are essentially measuring the length of wire by its resistance. If one coil measures a lower resistance, it means a shorter wire. How could that be? Aren't the wires still the same length? Well, no. A very hot motor will melt that dipped insulating material, causing an electrical short within that coil. The electric energy has a shorter path, and therefore less resistance. Once the coil is shorted, this is only recoverable via rewinding the motor. This may not be economically feasible or indeed, if the motor is potted in epoxy, complete junk. Heat is the enemy of motors. Bee

The purpose of the rewards program is to move merchandise. To induce purchases and generate cash flow. Yet there are models which languish, sitting idle in the warehouse. These occasionally make it to the outlet store, at large discounts. You got to move it, move it Why not combine these two ideas? An additional Hornby Reward on models that need to be moved from the warehouse. An uptick in the reward as a function of the model to be moved. A reward tier for those models Hornby Marketing wishes to enhance sales. Bee

Hello Paul When Garden Leave suggested a stepper motor, I assumed he was to couple the spindle of the turn table bridge to the spindle of stepper motor via helical, bellows or (heaven forbid) rigid coupling. This makes the pan of the turn table just a hole or depression in the layout The circular pinion in the pan would then be superfluous. That said, your experience dwarfs mine. By orders of magnitude. I defer to you sir! Bee

I should hasten to add. Hiding a seam from another person can be accomplished. Hiding a seam from the person who did the hiding? Not going to happen. You will always see it. I've some projects around that are many, many years old. I can never un-see that "thing". Bee

Hello Injury20 Re: hiding seams and joins. Flip the problem over! When making a joint between any two surfaces, you will fundamentally not be able to hide it by subtlety. I have found that emphasizing any joint fools the eye. For example, a fence or hedge, right at the line. The edge of a roadway. Etc. This trick is used quite often in woodworking, a joint is brought forward as a design element rather than being papered over. Re: those dowels. Please be very sure to allow plenty of clearance between the dowels and the holes they go into. Wood changes shape over time and too snug a fit will lead to you flexing the part to force it into position, destroying the materials on top. Yes to locating it via the dowels. No to a snug fit. Build in tolerance. Bee
