Product Description

Large On30 roundhouse

Release for 9, 10 and 14 degree angle options!

Made to order. 2-3 weeks manufacturing time.

This kit is intended to go with Kitwood Hill Models 13.5" and 16.25" turntables

Available with 14.5"stalls to use with the 54ft (13.5") turntables and 17.5" stalls for those modellers with the 65ft (16.25") turntables. 

There are 3 angle options and 2 stall length options. Table below shows availability and total sizes including the turntable. (plan diagrams are at the bottom of this description.)

If you run On30 locos then go with 9 degree if you can fit it, as it is more prototypical – and the door openings are wider at 2 7/8”. The longer length stalls can be used for additional machine shop areas, and mixed stall lengths can give a more interesting arrangement at the rear of the structure.

If you run K Class locos then you will need the 10deg version which has a 3.25” gap to get a monster K37 through the open doors. This is only available with 17.5" stalls. Both roundhouse and 65ft turntable will still fit on a 48" long baseboard.

14degree version is for space-starved modellers who need the roundhouse as close as possible to the turntable to squeeze every last inch – the compromise is narrower doors, but at 2 5/8” width through the doors, these are still wide enough for all Bachmann RTR locos including the 4-6-0. You can use the other rectangular KHM engine shed door options from the building depot for this option.  That said, who needs doors ?? – it’s not like you’ll ever close them!

The basic kit has 3 stalls - more stalls can be easily added. Indicate the number in the options list (max extra stalls is 4, to create a 7 stall roundhouse...this is a practical limit for shipping). If you want more than 7 stalls then contact me.
 
FLOOR templates used to set the wall angles also form a base for the floor into which tracks are set. The kit includes inspection pits. With plaster surface treatment this can be made into a concrete floor, or there is optional wooden floor planking. (On3 or On30)
 
WALLS are wooden boards over a wood framework. There are no side windows included to the kit but the framework allows provision to add the engine shed windows from the KHM "building depot" along with extra doors, or you can supply your own.
 
Apex windows are included. These are hinged and open and shut!
 
ROOF has a plain panel over the framework for a DIY covering of your choice. (tarpaper works well and is easy to do - info how I did it in the instructions).  The kit comes with roof stacks (2 per stall) which can be made with, or without, stays.
 
CORRUGATED IRON OPTION: If you wish you can cover the roof in KHM's industrial corrugated iron. For a standard 3 stall roundhouse with 14.5" stalls needs 2 packs of 10 (KHB002). 17.5" stall will need 3 packs.  Each extra stall added needs 3/4 of a pack (sorry!). KHB002 corrugated packs are available in the "Building Depot" part of the website.

Stall doors: as default they are included, but can be omitted as an option. Go to the KHM building depot to find alternative rectangular doors. Note the 10deg version has rectangular doors included as default. 9 and 14 deg stall doors have angled corners.

Check out the photos - scroll along in the images area. there are quite a few from the kit development.
