4mm SDJR No.25a - "Dazzler"

[Dazzler Fan]

I am attaching pictures of the current state of progress in the commissioning

of 4mm SDJR No.25a. for my layout of Writhlington Colliery c.1928.

 

The Loco was built in its original form in 1885 and the model depicts its form

immediately before it was scrapped in 1929.

 

 

The model, in 4mm, is only 84mm buffer to buffer, and is in two parts. Cleaning of

printer lines is required on the flat open surfaces of the Saddle Tank:unlike another's

experience, the internal Firebox is cleanly printed.

 

 

A compromise from 5'1" to 5'3" was made for the driver wheelbase to accommodate

available motion parts until a dedicated etch can be drawn. Detail is gradually being

added. The motor is from the Terrier, worm filed off, and replaced with 43:1 gear set.

The 9mm 6-spoke Pony (not shown) is part of the print. There is plenty of room within

for weight.

 

 

This has been a 15 year quest, collecting pictures and information. There are many questions

still unanswered.

Interesting result of an interesting prototype. Good luck with the rest of the work.

Nice idea!

I have been wondering about 3D printing as a way to produce some of the one-off locos on the Brighton (J C Craven bequeathed the company a large collection of locos that were almost all different). My impression was that the technology had not quite got to the necessary balance of cost and precision to make this viable. Could you tell us a bit more about the software and the printing firm that you used please? Would you do it again?

Best wishes
