I have started a kitbash to make a 2-6-8-0 from a Mantua 2-6-6-2. The drivers from a Mantua 4-8-0 look to be the same. I measured the driver and axle diameter and they are the same. Also, the 4-8-0 has an uneven axle spacing so one-rod set looks to match the 2-6-6-2
I got the Idea from the GN 2-6-8-0s . It will depend on what I can find that will fit the Mantua frame. I used a Lt Pacific shell on another 2-6-6-2 build and it fit great . I believe the GN engines had bigger boilers. I will make sure the the mech works good before I start the boiler.
I started to work on this project again. Need to let the CA dry and will try powering it. I have a bind somewhere right now.
Project update. Will be testing later today, if I am happy with results will add u joints instead of drive tubes.
Got the boiler from a Rivarossi heavy pacific / Mikado and after no cutting and filing got it to fit. this is just the beginning need to fine tune the fitment and add details.
I have decided to leave the stock motor in it. It can run very smooth and slow speed is great. It is a open frame 5 pole and the magnet is very strong . Do not know if it is the stock motor or not , but it mounts with factory mounting screw.
Thanks. I tried running my two Mantua articulated together and my 1st kitbash Mantua 2-6-6-2 runs faster,so no double heading for now. It has the newer factory can motor with flywheel the 2-6-8-0 is the tube drive with Factory open frame motor ,but is 5 pole. May just keep the open frame motor for now. The motor magnetism so so strong that when I added a crew with a tweezers it keep sticking to the motor and was had to place the crew.
