Bachman coal Tank in P4

[john lewsey]

Hi, I have recently converted a Bachman Coal Tank to P4. This is an easy way to get started in 18-83. It runs really nicely and was easy to do

Hi Rod, yes of course. Unfortunately I didnt take any photos

Hi John, what wheels did you use? Did they just drop in or is it a compensated chassis?
Hope all is well.
All the best

Hi, alan gibson does conversion sets for quite a few rtr models. There are instructions on his website.

I'm I correct in saying that the chassis is unaltered and it's more of a case of swapping out the wheel sets?

Hi Marc, yes it is. Gibson supply bushes for the connecting rods to fit the ag crank pins. The gear wheel has to be pushed off of its axel and fitted to the new one, then fit the wheels using a bb guage quarter them, fit them. Careful adjustment of the pickups is needed. Instructions are on Gidsins website

Sounds like might have to put one into the mix with my pug and Webb 0-4-0T then. Just need to find a small shunting prototype in the LYR/LNWR area of operations.

Thanks John, and to sidetrack I fitted a set of Ultrascale P4 wheels into a Dapol Pug many years ago and it ran beautifully. Very simple drop in conversion but they are quite pricey nowadays.

I have converted a Bachmann Coal Tank and one of the key features of the model is the fact that it comes complete with separate axle boxes. My only issue with the Bachmann model is that the coupling rods are very deep, on the prototype the rods are very delicate.

 

[David Mylchreest]

I wonder if anyone knows the depth of the prototype's rods?

I thought that would be easy to look up, but its not. Until a proper drawing can be found all I can say is about 3in.

I converted one to em a few years ago. A simple conversion & as you say runs beautifully.

You could always get someone to measure it

 

[Dave Holt]

They do look somewhat slimmer than the Bachmann version.

It's not the GA drawing but there is a dimensioned sketch on the LNWR archive that has the rods dimensioned at 3 1/2" x 1 1/2".
