DG's on 37

Compared to the class 45 with it's old Farish type couplings with coil springs, putting DG's onto my pair of new 37's was a doddle. They are fitted with NEM type coupling pockets which allow the N Rapido type coupling to be just pulled out.

Below we see a DG soldered onto a small brass block that is a tight fit in the NEM coupling pocket housing on the chassis underframe moulding. It is drilled and tapped 12BA and blackened. The screw is a countersunk one, also blackened.

The only modification is to drill and countersink the bogie keeper frame for the 12BA screw. The New DG coupling just drops into the pocket and nips-up tight with the screw. The coupling height comes out just right at the 4.5mm measurement above rail height that I use.

I originally purchasesd a split headcode 37 and a centre headcode one as well. Unfortunately research showed that the centre headcode ones did not arrive on NE Region until after Pool in Wharefdale closed in March 1965. Thanfully Andy Hanson was wanting a centre headcode one, so he purchased a split headcode one and graciously did a body swap with my unwanted one. Thanks Andy !
Next job is to carefully remove the existing tampo printed numbers and renumber them as Thornaby based machines. I've seen two approaches to doing this, cotton buds dampened with meths or T-Cut applied gently with a cocktail stick. I'll let you know which method worked best for me!

Dear Ed

Having read your article 'DG's on 37', I was wondering if these brass block and screw units might one day become available via the 2mm Scale Association???

You see, I like a number of the membership are not engineers so would find it hard producing such products. Also, the same sized unit might well fit future models such as class 20s, 25s, 31s, etc.

Maybe you might consider this?
