so i printed some loco lamps,

Need to sort a bit of light blead around base, and cab, but that's for latter:)

find the stl here OO/HO Loco Lamps by calvinstreeting - Thingiverse

There is sooo much printed stuff in this one photo :)

Ok
So i had a pair of old Hornby class 25 (well more like 1.75 class 25's). bothe with burntout ringfield motors

and wanted to see if i could save one and upgrade one to dcc an improve its runnings by:

1. changing the motor
2. removeing traction tyres
3. adding more pickups (all wheels)
4. add lights
5. add cab details (as had none).

Motor 1:
I sourced some replacement cd rom motors and rather than using a 6v replacement i found a 12v version on aliexpress

MABUCHI RF-300FA-11410 D/V 13.0 DC
https://www.aliexpress.com

and designed a bracket to fix it in place

Wheels 2:
As i had 2 (ish) i noticed that I could scavange the unpowed boggie wheels from both locos and combine into 1 set of non traction tyre versions. i know i loose some traction ut will add a bit more wieght to help that.

pickups 3:
Designed a bracket for the unpowerd boggie that i could put in bronze wires to top of wheel (would Have gone with side pickups, but the boggie has a metal frame and i wanted to avoid shorts. this method was also added to the motor mount (and a small piece for the gear side, to be glued in pace)

As a by product I had to remove the nub on unpowed bogie end, but that helped solve the lean. and i now have 8 wheel pickup

Lights 4:
Got some by colour (red/yellow, with common anaode) led's for headlights and yellow for cab and headcode light (which i cut a hole in the window glass so headcode and cab can be one light and folowing this guide https://loco-updates.uk/class-153-2/index.htm and added directional led's to front (one red/yellow and other side just yellow wiried up.

Cabs 5:
Ok i had none in the 2 (ish) loco's so out can cad and a few mins latter i had a set. (notice the motor end version is shorter due to gears, but i can live with that as some is better than none.

Done:

on the layout :) and alot better.

Next:

next need to sort some headcodes and some weathering to grim the to 1960's grime. and sort some headcodes, and onto a tender driven 8F that i wont to convert to loco powered.

update.. i have altered boggies and printed a set . (and used some temp wheels to make sure height is correct, as should be solid not spoked)

they are very detailed when compared to old Hornby ones (respraied old coaches)

next on to frame as i can print the 6 compartment 3rd class varient in one go on my printer (45feet on is just to big )

and then i can see if it roles

@calvin Streeting I can't help noticing the splendid seating in your designs. When you have got your own coaches sorted, if the seats could also be made available separately for filling out other errr ... "interiorly challenged" coach kits that would be great.

that sounds like a good idea (and they are seperate objects so should be simple :)

in other news print is now curing but initial view is:

A: better panel defernition (as now 2x real scale)

B: "S" hand rails seem to look ok embosed on side.

C: end panel detail worked (handrails on here will be wire)

but todo

A: door handles need a bit more stability as still break easy

B: Lugage racks need more as even tho 3 times scale size are still failing, so i might figure out other methods, or seperatly print

C: side wall thickness might need to be more as now with deaper panels has made them very thin in places..

and

A: need a bigger printer to print in one go, rather than spliting length :) any one got one , and want to see if it works ? (once sI have sorted A,B,C todos :)

Many thanks

now have underframe done.. mostly drawn for strenght (aka a bit thicker in places), ooo and buffers (but might compress them in a bit when i get to couplerings (thinking of adding a nem pocket to bogie.

did these have much under the frame ?

calvin

ooh and trying a increased depth panel and embosed handrail version print atm so wonder if it will come out ok

Calvin you are developing some very interesting CAD models.

I would very much like to print a test in 5 inch gauge scale of 27 mm/ft.

I'm just finishing a batch of wagon kits so I'll have capacity on my printers shortly.

I'd have to make the underframe in laser cut steel and the bogie sides and frames also in steel.

I already had a plan to draw a Midland clerestory carriage as my next project (maybe after the Midland single verandah brake van, which is very much requested) but if you would be prepared to share your model, it would speed up the process very much.

ooooh

intresting, i am sure i can share copies of the 3d models etc

and even tho i am working in oo scale, i am drawing correct scaled size and then making it larger / thicker to compensate for scale.. :)

so lets see what we can do :) as good to test models on other printers / systems / scales

Many Thanks

calvin

I am atm thinking to print main underframe on fdm printer in ABS to get strenght / flexible base, and then resin body and maybe boogies for detail :)

and i looked at your wagons :) love the sprung buffers.. as was thinking obout the same lol

January 10, 2023

right test print 1st class compartment (hot of printer so not UV cured)

panel detail is visable, but might want to incress the depth of them (again fight scale v real world)

door handles and handrails, way to fine for real scale replication. so..

Thickern up and maybe embose of coach side
use wire, and other materials

but it got most of the detail esp tiny hinges, and the vent outside looks scaled ok (but paint might fill the gaps quickly

the interor... :) happy with seats very with texture. , but luggage rail needs more to be thicker and maybe add a net representation, and vent needs a bit more thickness..

I suppected most of the thin parts would be sus.. but happy on the most part as is first print...

and i have a ROOF :) so its buffers, under frame and some amendments / tweeks

calvin :)

wonder what a O gauge would look like :) lol ... back to OO as havent got room for that

January 9, 2023

ELEGOO Saturn 192x120x200mm
Elegoo Mars 120x68x155mm (mine)

that extra 5 cm makes all the differance :)

but i draw it whole, and plit if needed.. as i can always 1: use a print service 2: buy another printer :)

I have to apologise as it has dawned on me that this drawing, Drg. 589, is for a type not built! This one has three first class compartments. The type actually built, to Drg. 617, had two first class compartments - the middle two. The Study Centre has a copy of Drg. 617, item 88-D0373, but I don't - I don't know if it has yet been scanned.

There were 80 45 ft carriages to Drg. 617 built as composites, with compartments arranged Lug/T/T/F/F/T/T, diagram D513, Lot 108, and 20 built as brake composites, Bke/T/F/F/T/T, diagram D526, Lot 109, all ordered in march 1884. It will be straightforward to adapt your cad, as the third class compartments were 1' 3" shorter than the firsts, so the luggage compartment 1' 3" longer than on Drg. 589 and the double doors moved 9" further from the end and the RH door made the standard 2' 0" width. The 1' 10" width on Drg. 589 is to fit the double doors within the restricted length of the luggage compartment; perhaps the need for this non-standard component was a factor in this design being dropped in favour of Drg. 617, although a Traffic Department decision about the amount of first class acccommodation needed was probably the main driver.

oh my :) i am thinking that is if i draw it in sectios (1st class, 3rd Class (normal and at end) and various luguage compartments, then should be able to asemble various like using lego :) i am going to have to split the job for printing as its 1.5 cm larger than my print box :) but thats another issue

many thanks

A Partition between a Third Class compartment & a Luggage compartment?

oooh nuts.. so mised one 3rd class :)

thanks

calvin

January 9, 2023

Sorry another question do we know what happens in the end compartment ?

January 8, 2023

Interior (basics) for 3rd class :)

just trying to get enough to test print

calvin

January 8, 2023

question :) do the doors open same way on both sides

there is something very pleasing withthe way this is starting to look :) (note the drawing is not 100% to scale on X axis as drawing might hve been streched when scanned, used to happen on my old drawing board ... back in the old days of pen's :) but i have drawn this to scale dims from the drawings

calvin

and now with a curve :)

@calvin Streeting Interesting! I dunno whether this is relevant to your bogies, but in later Midland days other coach bogies were fitted with helical springs in place of the elliptical transverse ones. I expect @Compound2632 will have chapter and verse on this.

@billbedford I believe you were working up 3D printed MR bogies. Is this still in your plan?

intresting.. i am drawing it for printing, as i have used my printer to make senary items (see https://www.thingiverse.com/calvinstreeting/designs ) and i recently got a resin printer and thought i know wonder if i can do trains / carriages etc now :) and the carriage is first, so i thought can i print some slightly shorter old style (love onld midland coach, with an air of style glamour).. hence i am now working on modules (ist class compartment, 3dr class, brake, luggage etc.. so can make many difernet types :) and when done i will probley end up sharing my models as they only got draw by others sharing drawings etc.

many thanks

dam.. "30 Ft. CLOSE-COUPLED FIRST CLASS 6 WHEEL CARRIAGE Diagram No.262 Drawing No.547 Dated 1882:" is a 404 error anyone got a copy downloaded ?

Hi Calvin,

You might like to make a close study of Drg. 547 of 1882, Midland Railway Study Centre item 88-D0001, a scan of which is available for download. Although this is for a 30 ft 6-wheel first, all the body details, panel dimensions, etc. are the same as for the contemporary 40 ft &c. bogie carriages. The door and window dimensions are the same for third class compartments as for firsts so the only adjustment that needs to be made, from an external point of view, is reduction of the distance between partitions from 7 ft 3 in for firsts to 6 ft for thirds.

perfect.. even comes with interir drawings :)

January 4, 2023

thought i would show a update.. I test printed the boggie and have had to thinkern up a little (the foot plate, and supports. scaled in hight the springs.) for stability and to make it printable. but was supprised with the detail it did manage to get.

I also have started on the cariage sides (in sections), note: yet to curve bottom as easyer to do that last, found some good photos of a few various midland (or LMS ex midland) coaches to help with details and is that edge rounded etc :)

calvin.

January 2, 2023

ok a update.. had to thickern window bars to avoid/minimise warping. and a adjustment to the window crank handle to stop it snaping of :)

but got enough to dry asemble/test fit (using blue tac to keep it in place. and seems to work. the valance/roof hieght is a bit, but dose give room to hang the crane over rolling stock i suppose :)

January 2, 2023

I personaly would recomend blender (it has more control than sketchup, but is a bit more complex to learn) a good resourse is https://www.youtube.com/@ArtisansofVaul as he talks alot about modeling for printing, hut also alot of other videos about basics of software.

What scale is this anyway?

I have a oo layout, :) so yep i am altering a fw things for scale/print/model use etc. and unless this derails i doubt i will see much of the under carriagei :)

and thanks for the coach pics/ref as they will be helpfull for drawing. I am doing this as want some shorter coaches that are not 6 wheels, (and love the old panel style), if this works I might do more but this is first carriagei have tried to make

calvin

January 1, 2023

Do you meen this bit on lower (under middle springs) is a blank rather than battern style

once again thanks for helping :)

note: upper wood is filled in to provide support for fixings etc

I think you need to look at the arrangement of the bolster again.

i can see the main (mid) spring was way more open on the photo v the drawing. but i jiggled it around a bit to A: better suit printing, B: look more like the photo.

also moved diagonal braces a bit to allow 12.1 wheels, so its time for a test print, and find a body drawing... then work out couplerling last as that would not be part of any drawings ..

calvin

so in 4:hrs ish as printer is printing a coach shed part atm

January 1, 2023

oooh thanks. i can see that photo also has the brake shoes :)
