Poole version Farish 158 conversion
« on: March 31, 2020, 03:16:45 PM »
I have acquired a Poole Farish 158 and was intending to perform two modifications to it.

The first is so it will fit in a Farish Mk1 carriage bodyshell to become a motorised 205 unit.

The second is to convert it to DCC.

What I have now discovered is that I should have bought a China version!

Searching through the forum I see that conversion may be possible but the links are so old they don't exist anymore!

I'd be grateful of any advice beyond put it back together, sell it on and buy a China 158 or 170.

Graham,

It is possible to convert it to fit a Farish MK1 bodyshell, but depending on whether its's a Spring Drive or Drive Shafts will depend on how easy it is to do.

I've done a couple of the Drive shaft ones but have tried to steer clear of the Drive Spring ones, however the chassis block modification is much the same.

Basically you need to saw off the wings at the end of the block and turn the Gear towere clip on the top round and back a slot. This also means you need to shorten the Drive Shafts or Spring by a few MM, but I'm damned if i can remember by how much, I've got it down somewhere just got to trawl through my HDD to find it.

As to DCC conversion, not my territory I'm afraid..

Good Luck

Cheers

Neal.

Just done another conversion on a spring drive 158 (my fourth) to fit in a MK1 coach body.
Strip it down so that the armature and attached springs can be taken out of the chassis block.
Remove the white nylon bearings; three each end; and remove the spring from the armature. It helps if you mark the armature to show how far the spring goes on when being replaced.
Measure the distance between the two holes for the bogie mounting clip at one end of the black plastic chassis top - its about 6 mm.
Mark 6 mm in from the closed end of the drive spring and cut off the excess with wire cutters. File the cut end smooth and replace the drive spring onto the armature shaft up to the mark. Repeat for the other drive spring.
Before reassembling, take the bare chassis block and file or saw off about 5 mm long by 2 mm high from the block sides in line with the new centre of the bogies. This prevents shorting between the bogie pickups and the chassis block. Reassemble and put the bogie securing clips into the inner holes in the black plastic chassis top.
I can provide photographs and more detailed instructions if needed.

That's very useful and interesting. I'm sure photos would help me and maybe others.

Now I know that's possible (And before I start) I need to work out how to convert to dcc. I think I need a digihat but they don't seem to be available anymore.

Yes please, especially as I have a couple to be done.

I feel an NGS article coming on here  ;) ;) ;)

Just to add confusion, I have just received a scratch built class 404 'Nelson' EMU using Farish MK1 coaches and powered with what looks like a modified Dapol class 121 chassis which is DCC compatible/fitted as standard.
Right wheelbase and correct bogie frames.

Oh wow! Any chance of a photo so someone could confirm or can the previous owner advise?

There should be some photos in the gallery showing the Dapol chassis used on the 'Nelson' EMU.
The DCC wiring has been cut about so I had to add the red striped wire to the motor terminals so it would run.

I can see it. As it's been a while since I touched a 121 I've no idea if it is. Does it say Dapol on the underside?

If it is I guess the price of 121's just went through the roof.

Tutorial on conversion now available.
It is the way that I did it, other ways may be available!

I'd be interested to know more on how you did the Dapol chassis mods. It could open up an alternative to the suggestions to my kits for the 204/205/410/411 and some of the others I am currently designing.
