NER T2, LNER/BR Class Q6 chassis kit. Price £55.00 including 1st Class P&P, UK Mainland only. Overseas carriage will be charged at cost. for details on how to order ring 01670 362451 or by email from the "Contact Us" page.
 
 Photo © Peter Stanger.  This is the one that started me off designing and producing self-levelling chassis for kit built 4mm scale model steam outline locomotives. This is a photo of one of my stud of Q6's fitted with the Easi-Rider loco and tender chassis.  Before it was converted to EM and I had a large OO layout, this loco used to regularly haul 60 wagons at realistic speeds.  This loco has excellent slow running properties as well as a fair turn of speed when required. 
We can supply Gibson loco driving wheels and crankpin sets for all our loco chassis kits. See "Gibson Wheels" tab for prices.  If ordered with one of our chassis, the wheels and crankpins are post free.  If ordered seperately please add £1.50 to cover P&P. 
 
If ordering by Royal Mail then please enclose a contact phone number or an email address.  In the event of a query it can save a lot of time.
 
This is our first chassis kit designed and manufactured by 52F models.  It transforms the running and looks of any rigid chassis Q6 model in OO, EM scales. Although not originally intended for P4 modellers, there have been six chassis built to P4 standards.
 
One of our chassis was tested on Roy Jackson's "Retford" EM gauge layout with a load of 60, wagons and performed faultlessly.  Roy Jackson was at the Glasgow Show in February 2009 and he had the DVD of the Q6 running on his nationally acclaimed layout.
 
 
 

 

 

  

Image © Peter Stanger.  This computer generated image is of the assembled Easi-Rider Chassis for a LNER/BR class Q6 locomotive.

This image clearly shows the self levelling mechanism with the motor and gearbox incorporated into the rear compensation unit.  The recommended motor (not supplied) is a Mashima 1420D as shown in this image.

 

The image clearly shows the new etched cylinders with new slidebars and crossheads, the new motion bracket, new centre frame stretcher and new rear footplate suports. The new frame stretchers incorporate the brake hanger pivots. The brake gear is assembled as a seperate unit and is removable should this prove to be necessary.  The only soldered parts are the front and rear frame spacers, the motion bracket wrapper, the rear footplate supports, the cylinder slidebars and front and rear cylinder covers. The captive nuts on the inside of the compensation beams are soldered in place.  The whole chassis can be built unpainted, tried out and then completely stripped down for painting. 

 

The chassis was designed to be a direct replacement for the Alexander Models class Q6 locomotive with a minimum amount of alteration below the footplate.  The chassis can be made to fit the older and less accurate Nu-Cast Q6 with only minor alterations to the rear frame extensions and the rear brake pull rod.

Above is the Easi-Rider Q6 Loco and Tender chassis in EM gauge. The photo shows the etched parts in 0.45mm nickel silver and all the other parts included in the kit.  The crossheads are pre machined and drilled and tapped 14BA. The piston rod tubes are pre drilled Ø1.2mm to accomodate the piston rods.  The 2-stage reduction gearbox is incorporated into the rear compensation unit and comes complete with a 54:1 gear set and a 2mm bore brass worm.  Intermediate gear shaft and spacer are pre machined to optomise the position of the intermediate gear relative to the worm.  Also included are loco and tender axle bushes and a pre machined pivot tube for the tender compensation arms.

 

The kit is designed for ease of assembly and a minimum amount of soldering.  The assembly instructions contain a parts list, 2 diagrams and 9 pages detailed instructions.  This kit is available in EM and OO gauge versions.

Instructions.  The kit comes complete with 9, A4 pages of assembly instructions, 2, A4 assembly diagrams and a 2 page parts list.

 

Chassis   Easi-Rider, self-levelling, designed by Peter Stanger, produced and marketed by 52F Models. This conversion incorporates a host of new features. The etching is in 0.45mm nickel silver.  This chassis is available in either OO or EM gauge versions.  Several customers have successfully built the chassis to to P4 standards.

Construction. The loco and tender chassis are folded up construction for ease of assembly and to keep soldering to a minimum. The self-levelling units work independently of each other and the rear unit incorporates the locomotive drive train.  The loco axle bushes are a light press fit into the self levelling beams/unit and can be removed to facilitate disassembly should this ever prove to be necessary.

Drive trainThe revolutionary new drive system is incorporated into the folded up rear compensation unit. The drive unit is a 54:1, 2-stage reduction gearbox and a motor mount for a vertically mounted Mashima 1420D motor. This configuration allows the gears to be in perfect mesh no matter what the self levelling unit is doing.  The intermediate gear shaft is machined to length and a machined spacer is provided to keep the intermediate gear in alignment with the motor worm.  The design and assembly method ensure a perfect result every time. 

Cylinders. The new cylinders are etched nickel silver and are designed so that the piston rod centre line lies at a prototypical inclination of 1:20 through the driving crankpin centre line.  A new redesigned, etched, 2-piece motion bracket incorporating the brake hanger to mounting, supports the rear of the slidebars. 

Slidebars. Slide bars are made from 1/32nd square brass and are located in both the front and rear of the cylinders for perfect alignment and maximum rigidity.

Piston rod guide tube. These are Ø1.6mm brass tube, drilled out to Ø1.2mm and located in both the front and rear of the cylinders.  This tube is machined to a length of 15mm and is matched to the crosshead piston rod.  If assembled correctly, no further work should be necessary.

Cylinder wrappers. These are etched in 0.45mm nickel silver and are bent around a Ø6.35mm drill shank to form them. They snap into position and need not be soldered in place.

Crossheads. These lost wax brass castings are machined on the inside to ensure the connecting rod sits on the slidebar centreline and the leading driving wheel crankpin doesn’t foul the inside face. These items are tapped 14BA to allow the connecting rods to be fitted and removed if necessary.

Coupling Rods.    New 3-piece, double thickness fabricated from nickel silver with prototypical 5’-7” – 5’-7” – 6’-0” wheel spacing. Three-piece coupling rods assist the locomotive around curves and are essential if any form of
self-levelling is to be undertaken.

 

Connecting Rods.  New design, more prototypical looking with double thickness for approximately half their length.  these rods are fitted to the crossheads using a 14BA screw and could be removed should this prove necessary.

Brake gear. New frame stretchers are included and incorporate the footplate support brackets along with the upper mount for the brake hangers. The loco brake gear is designed and fitted as an assembly and can be removed to make wheel fitting and removal easier.

Electrical Pickups. Provision is made for Gibson, plunger type pickups on the locomotive driving wheels only. (Not supplied) With the Easi-Rider chassis, tender pickups are unnecessary. American style of current collection can be used if preferred.

Motor/gearbox unit. Peter Stanger designed unit. The gearbox is incorporated into the rear compensation unit and has a motor mount for a Mashima 1420 flat can motor (not supplied) with custom flywheel. Gears are 54:1, 2-stage reduction with a brass worm and final drive gear. Intermediate gears are Delrin for smooth silent running.

Tender Sub-chassis. This is fold up construction and allows self-levelling. Wheel spacing is a prototypical    6’-4” – 6’-4”. The leading and middle axles move up and down in slots in the chassis supported by compensation beams.

Tender brake gear. New double thickness brake hangers and shoes and redesigned rigging allows a prototypical look and accomodate wheel removal without the need to un-solder the rigging.

Performance. The chassis has excellent slow running properties with a very good turn of speed.

Load hauling ability. A OO version has been tested on my own layout with 60 wagons and will negotiate Peco Streamline small radius point work (24” radius curve).

 

Easi-Rider self levelling Loco and tender chassis with a Mashima 1420 motor (not supplied) in place.  It can be seen that there is room inside the firebox for a custom made flywheel to be fitted to the motor should this prove to be necessary.

The rear 3/4 view of the same loco shows the new lamp irons to good effect.  The top iron has five bends in it to achieve a realistic appearence.
