You can use imperial and scale as such......I think, pretty sure Jim (US) has his set that way.
I've got mine set to 0.05mm which is good enough for etch work as a whole I find.

I'm not sure if this is true but I'm sure I read somewhere that the Russians built copies of the Boeing Superfortress, re engineered in metric which caused problems.

Sorry Brian don't mean to hi-jack your excellent thread.

All the CAD systems I have used can work quite happily in Imperial units - Fusion360, AutoCAD LT, Draftsight, NanoCAD. It's great for taking dimensions from drawings in Imperial units which can then be re-scaled to metric if required.

They did. In 1944 some (memory is 4-5) B-29s diverted to Soviet held territory due to lack of fuel/damage. The crews were eventually returned but not the airframes. Some of the aircraft were taken to the Tupolev factory where one was stripped down to reverse engineer a copy to meet Stalin's demands for an aircraft to attack the USA with the Atomic bomb that the Soviets were developing from information obtained through a massive spying effort (This aircraft would not have the range for the job but obtained technology that could). Within a year the first soviet aircraft was ready for inspection. This was a massive achievement as the American aircraft used imperial thickness materials and alloys unknown in Russia; they also had to develop cloned engines. The Soviet copy was less than 1000lbs heavier than the 120 000lb American aircraft.
From this Tupolev developed a line of aircraft that were capable of attacking the USA and that are still in service today (the TU-85 Bear first flew in the early 1950s and is now receiving new attack weapons so that it can do another 20 years in service. This mirrors the B-52 Stratofortress that will do 100 years on the front line.
Thanks Brian, SimonT is leaving the building!

Ian is correct. If you want to get mathematical, 1:43.5 is an approximation of 7mm:1ft. The true value is 1:43.54285714285714(approx)!11' = 123" = 3352.8mm ÷ 43.5 = 77.07mm

No worries about a little diversion as it's an interesting read.
Mickoo I already downloaded the valve gear bits from the Finney7 PDF
I have built a DJH A4 with working lubricator so can I do it a second time? I got a couple of whitemetel lubricator boxes from Ragstone Models just got to make something to attach them too!

I have my units set to 8 decimal places, or 256ths if using architectural units. Not because I ever intend to go to such extremes when creating drawings. But rather because for me one of the primary qualities of cad is the precision involved. There's no sense in my opinion in being casual with the numbers when you can be purposeful. I'm also compulsive about things, so I tend to quibble even when it isn't necessary.0.4mm give or take
You can use imperial and scale as such......I think, pretty sure Jim (US) has his set that way.
One other thing that has changed my perspective a bit as well is diving into machining as a discipline and potential vocation. In machining terms, a 64th is almost 16 thou, 5 thou would be a generous tolerance in many cases. You might as well be doing carpentry at that point if those are the standards you're working to!!!
I presume you're talking about snapping to a grid with this comment? If so, I never ever have the snap on, unless by accident, as it's next to the F8 ortho toggle function key and I sometimes hit F9 by mistake. I prefer to simply draw things as they are meant to be, as Autocad supports the dynamic entry of distances and angles within nearly all drawing and editing commands. It's really quite simple.
Also, it's quite simple to switch from imperial to metric even if the drawing has been started in the opposite style. The "dwgunits" command will walk you through it.
Jim (US).....should change all of my users names across multiple forums to this....

I have been building a few of the Paul Rolly/Intentio resin wagon kits recently. They are basic but when built look like what they should when running round and round and round. I added a load from Goodwood Scenics stuff which looks convincing I think.

UK high sided gondolas... the certainly look the part.
Don't some of these run in fixed sets with buckeye couplers or is it only the coal hoppers?

DB have EWS maroon ones with buckeyes and a few with swing head couplings on for outers. Here is one with a swing head coupling.

DB hoppers were all built with buckeyes and no buffers but some were rebuilt with screw couplings a few years ago to work with class 60's. Here's a conversion.

So this is what I have been doing recently, building a Heljan diesel depot kit and back dating a Heljan 50 to original spec. The 50 was done with some etches from Vincento on ebay. I have also been adding a few details to the shed as it's a bit plain as bought.

A couple of more shots of the shed. It's still got to be blended in round the base. I did not ever think I would have a shed building on this layout so it's an afterthought and a bit of a tight squeeze to get it in.

Dug out an old MMP 08 that I built when it first came out I think but it needed a bit of TLC on it. I renumbered it as originally I did it with sector decals on the cab side and I didn't want them now. 08792 fitted the bill with number now in fuel tank. Had to repaint the cab sides now though after removing the decals and 08792 had black cab sides anyway. Added a JLTRT electric fuel pump float switch part above fuel tank. Added a JLTRT vac pipe. Main bit I have done is illuminate the front markers with fibre optics plugged into the top of an LED in the hood. Unfortunately I can't fathom out how to get the rears illuminated now it's all built and painted. Also put a nano LED into the cab roof. Cab roof was a terrible fit if made as the kit came so I have modified it now for a better fit.
