Large Scale Central

Mogul Chassis from LGB Spare Parts

Made from two dummy drive blocks left over from a LGB LCE repowering exercise. I wanted a staggered axle Mogul drive for another project and decided to use some parts laying around. Drive blocks must be bonded with high-strength epoxy glue, as solvent glues will not attach the parts. LGB Mogul drivers are fitted to the standard four-wheel block LGB axle (the Mogul gear as supplied on the axle is too large a diameter and will not fit the gearbox drive). First axle is rod driven. Second and third are motor/gear driven. Rods are modified B’mann Anniversary. Power pickups are a slight problem as the drive block is designed for smaller diameter wheels and not the larger Mogul drive wheels. I will devise a suitable power pickup. Sliders are able to be fitted as per standard LGB design. Drive will be fitted to a modified (shortened) Anniversary body. I need to bond 0.030" styrene to the sides of the drive block to enable detail parts to be fitted and also to limit sideplay in the axles (as I do not run R1 radius curves).

Neat idea Tim.

Interesting project!

Due larger wheel diameter, sliders are not able to be fitted. I modified an older 2010 series slider to fit, but, as it was obtrusive, I decided to rely on wheel pickup only.

Progress to date - styrene overlay applied to drive block sides and detail in process of being applied. Power pickups fitted and block test run. No-load amperage 0.30, with point of stall 0.89 amps. Block runs very smoothly and is extremely quiet. Will complete detail installation and then proceed with the rest of the locomotive.

Detail installed. Little more than ‘clutter’ to represent a chassis sideframe.

Chassis to date. Original Bachmann moulding is little more than a ‘saddle’ to mount the drive block. (I know that it is not a Mogul configuration!)

What’s that rough, brownish thing on top?

Ray, that would be a weight to increase traction, I beleive!

Ray,
that is the standard cast iron weight fitted to all B’mann Anniversary locomotives (and many others).

Almost complete. just detail items to fit. Boiler shortened by 1 cm just forward of cab. Tender made a couple of years ago from a Big Hauler body.

Nice!

Sweet!

Today, I revisitted this project as I was only 99% happy with the outcome. At extremely slow pace there was a slight binding, even with the rods removed. As an experiment, I removed the aft axle and interchanged with the non-gear driven leading axle. There was an immediate improvement in low speed performance with no trace of binding. Now only the centre axle is gear driven.

Hmmmmm Are your drivers correctly quartered?
