The Digi Hat from DCC Supplies is used to convert Graham-Farish chassis safely to DCC in minutes!

Supplied with Kynar® heat shrink tube. Tougher than standard tubing, and half the thickness!

Q. So, the spring is a fuse?
A. No. The spring is made from 0.32mm (28awg) Beryllium copper wire, which has a capacity of 1.4 amps. Or, put another way, most 'N' gauge decoders provide 0.8 -1 amps. The current draw of an average Farish motor is 0.3 - 0.4 Amps.

Q. OK then, will heat draw the temper of the spring?
A. No. Beryllium copper is tempered at
460° C for an hour. With a loading of 1 amp the temperature increase of the spring is negligible. (see below)

Q. Does the spring get hot?
A. No. At 1amp heat generation is 0.003 W/second (per 1000m of wire!), heat dissipation is 105 W/m*k, again, well within tolerances!

Q. Will the DiGi-Hat melt?
A. No. The material has a melting point of 140°C.

Q. Is it true the DiGi-Hat™ absorbs water, expands, and splits?
A. No!
The material used (a copolymer of Polyoxymethylene) is designed for use as a bushing material, and is specified at less than 0.5% absorption at 100% immersion. (measured by ISO 62-
Sat/23C) - and after all, we're not discussing submarines here!

Q. What makes this the best solution?
A.
DiGi-Hat™ is a designed and engineered solution. It uses high quality materials chosen specifically for the task, and engineered by a specialist company with over 35 years of experience, under compliance with BS EN ISO 9001 : 2000

Wanted to convert some old GF panniers, heard about this product so decided to try. This was my first attempt at this. The product made it so easy with the detailewd instructions. Would recommend this to anyone.

An excellent piece of kit, fits nicely in my P4. Six more Locos to do.

It is really easy to set this up i did a GF class 47 within 15 minutes there is nothing difficult about this follow the instructions given and you will sail thorugh brilliant & easy

I'd heard and read a lot about this product, some good, some bad. So, I decided to try one for the price.First impressions were that it's a very well made item, excellent engineering, and no signs of flash or other manufacturing problems. I tried a 'dry' assembly, using a spare brush and spring, and the fitting was excellent, nice smooth operation of the brush and spring, with no excessive side play.Fitting to the loco (an 0-6-0 tank) was very easy, just remove the base plate, and swap the brass hat with this one. Again it fitted the chassis well.I used the kit version, as I wanted to see how it was made, and the clip (which DCC have modified) had the wire fitted on the side, (under the sleeve out of the way of the wheels), they also use a very thin coating to insulate it, which is extremely tough, but thin enough to avoid problems of wheel binding (this is also supplied with the plain digi-hats). Whilst it would be OK without, I did file the chassis a little to help the clip fit.As I'd read about overheating and other dire warnings I decided to run this on DC for a while, and set-up the rolling road, it seemed to run ok, so I left it for some hours running at full speed. When I checked, the motor was hot (as you would expect), but the spring and 'hat' showed no sign of any problem. I then repeated this with a DCC decoder fitted, without problems. I've since dabbled with 'OO' gauge sound, and notice that the wire gauge used on loksound decoders is as thin as the spring - and these carry almost 1 amp!)Overall:Minimal skill is needed to fit, though a steady hand is a must (the brush and spring can be tricky!) this is a very nice modification, and doesn’t need any drilling or filing to fit. It’s obviously been well thought out, and it's detractors have obviously little grasp of electronics. I've since fitted my whole stable with it, 24 locos of various vintage, and all run very well.
