Brian Daniels diesel workbench

[Brian Daniels]

Wheels are standard 3/16th Slaters. Instructions say tender are 3'7" and bogie and pony 3'1" which is what the model has.

Brian,

That's fine, are you going to Bristol?

If so I'll have some replacement overlays for you that'll fit (pending PPD delays etc)

Best MD

 

[Brian Daniels]

Yes I will be at Bristol with it, demonstrating with my JLTRT 25/0 whilst I am there. Be great if you can get some that fit done. brilliant, thanks.

 

[Brian Daniels]

As it has been a year since I put anything on my workbench thread I will look back and see what I have been up to. First up is a Heljan 37 detailed with a DJH re-furbished conversion kit.

 

[Brian Daniels]

Heljan 45022 with the headcode changed to a 4 character centre headcode.

 

[Brian Daniels]

A JLTRT as 47004.

 

[Brian Daniels]

My 4TC converted from 4 JLTRT MkI's. Here it's running on Pete's Leamington Spa.

 

[Brian Daniels]

Heljan 05 now in industrial use, ex CEGB.

 

[Scale7JB]

47 and 4tc look great Brian!!

JB.

 

[Brian Daniels]

Done all I can at the moment until I know it runs ok.

 

[Brian Daniels]

Been doing a bit with a Heljan class 20 as well. Added snow ploughs and painted the buffer shanks silver. The chassis is a tight fit on the chassis so whilst it was out I filed a bit off the chassis by the cab and now it goes in ok. I have removed one motor from this and another I have to see if I can run a pair without overloading the controllers!

Brian,

It's something I have contemplated so can I ask if you will post the results of these 'tests'. Incidentally, what DCC controller are you using?

Peter

 

[Brian Daniels]

Just running these on DC Peter but I will let you know how a loaded run goes.

Just running these on DC Peter but I will let you know how a loaded run goes.

Did a run with these single motored 20's and they ran just like single one. I had 22 wagons on and I even ran it with one loco which it seemed to cope with ok.

 

[Brian Daniels]

As the Bristol show is looming I thought I better do these flange lubricator boxes on 37425 that I had 3D printed some time ago.
There are a few .5 holes needed drilling but I still could not do all the pipe runs coming out as there just was not enough room. Think it looks the part but just wondering how well it will show when it's painted. I think some gentle weathering will be needed to highlight it.

 

[FiftyFourA]

Thanks Brian,

Was this run on your outdoor circuit as shown in your YouTube videos?

It tends to support what I have long suspected about Heljan locos being over-powered and the second motor superfluous.

I think I may try taking one motor out of my Cl 25 - it will certainly make converting to DCC alot cheaper

Peter

 

[Brian Daniels]

It was on a nice flat club indoor layout Peter.

 

[delticfan]

If you took one motor out of a Class 20 would you still need an XL sound chip to run it or could it be done with a smaller cheaper chip, without loss of sound and running quality.

 

[Brian Daniels]

Good question, you would have to do a stall test I think to find out its max amperage.

 

[Kev T]

From memory the 20s have a quite high current draw. I suspect that the stall current will bo OK on one motor though. If you have an ohm meter the easiest way to check stall current is to read the motor resistance,I.e. just measure across the wheels. Apply ohms law to the reading. V=IR. For example, if the resistance is 6ohm and your track voltage is 12v, then the stall current is 2A.

This comes from the fact that at stall there is no back emf and dc conditions apply.
