Thread: Need help with meddling pillar drill.
15/09/2019 10:57:21

I made a bad mistake last night and now my pillar drill as stopped working. I overlooked that my battery charger was still plugged into the extension lead along with pillar drill when I turned on the power. The charger clamps had made contact. The fuse was blown on the extension lead which I replaced. But now the pillar drill will not work. I have checked with a electrical wire tester and power is going to the drill motor and the switch. Is there a fuse inside the meddling drill, or have I blown the motor. If it’s the motor who supplies replacement ones. Thanks, michael

Hi Robert, here are further readings.

Black to brown. 3.9

ground to green/brown. Ol

case to black. 1.3

case to brown. Ol.

thanks, michael

Hi Dave. Ok these are the figures. Black to green/yellow=8 ohms. Brown to green/yellow 4.5 decreasing. So with this new info. How or should I wire my two controller wires. Thanks, michael

Hi, yes I do have a multi meter. There are two of these dynamos wired so that one works forward and the other for reverse. I only wish to wire up one dynamo. So Dave if I am reading you correctly.both brown and green/yellow wires to positive and black to earth.

Ron I do have a 2nd loco that I am going to fit in the 500w motor and 36v. I need to purchase a L/H tap tomorrow from Tracy tools to be able to fit the old chain gear to the new motor. But that’s a difference project from this one. I am keeping the old dynamo on this one as I don’t have time available to make or find new fittings for a new motor, so would just like to get this working to use over the next few months.

Thread: Long tender means the controls need extending

Thanks Nigel. Lots of input. I have spoken to a chap using a Bowden cable for regulator and it clipped onto the rear wall of the tender. However as you stated the injector controls would be a lot harder to deal with. I like the idea of placing the tender controls at the rear. Thanks. Michael

Hi, thanks for getting back. But it’s not about being a cheapskate, it’s about knowing how to wire it up to a two wire feed. It did work on 12v. So I just need to know which two wires to use.

Hi. Not to sure that would work due to the heat, and I would always worry about fire from the firebox catching any servos.

Hi, I am trying to wire a controller to this motor. The controller as a live and negative outlet wire . But the motor as three wires. Can anyone please let me know which wire connects to which. Thanksf1f905c0-df76-4eb8-aa29-47e10b6b51e7.jpeg

Thread: Long tender means the controls need extending
04/09/2019 13:07:24

hi. I am coming to the end of my Martin Evans designed Columbia, and need some help. The tender is very long and there is no way I will be able to get to the controls. I have figured a way to extend the regulator by using a Bowden cable. But what is the best way to extend the injector valves. Thanks.

Thread: How to wire a 4QD controller
29/08/2019 14:02:04

All sorted, rang the company and had a step by step walk through. It’s easy once you know how. Thanks again for all your interest.

Thanks Bill, will phone later today.

Hi chaps, I am a complete thicko when it comes to wiring. I am trying to understand how to wire 36volt battery’s to the control. It’s as clear as mud to me what wire needs to go where. Is there anyone out there who understands the black art of electronics who can help me out. Thanks.

Thread: Need a lot of help from you good people
22/08/2019 10:40:39

Hi Robert, thanks. Just ordered three batteries, new control unit from 4QD and a 500w motor. So will see if it all works, when it turns up. Should be interesting. Michael

21/08/2019 17:12:22

500w 36volts.

20/08/2019 18:45:35

Thanks Dave.i have removed both motors but there is nothing on them. I think it’s time for both of them to hit the bin. So far I am looking at a 500w motor to run the loco. My problem now is what battery’s to use. If I go for leisure battery’s I will be adding a ton of weight. If I go for more modern battery’s it’s a mine field. But if I am to keep it,I know I need to keep it simple. So chaps the question is what battery to run a 500w motor for say 3/4 of an hour. With one maybe two adults. Thanks.

20/08/2019 17:12:45

Hi Ron, I have know interest in pulling people around and the club I am a member of doesn’t do public running. Fitting a 1000w motor in place is not an issue. However the battery’s are. At the moment I am thinking 500w motor but still stuck with what battery or battery’s to use.

20/08/2019 11:21:00

Hi. Thanks for all the physics. I have a question. Would fitting a motor from an electric bike and a 48v 15ah battery with new controller work. These motors come in 350w 500w and 1000w. But getting information on the torque they produce is hard to get. Surely there must be an answer to this.

19/08/2019 20:59:50

Thanks Robert, I am in Somerset. Commutator skims, new brushes are way out of my knowledge. I have always been a hit it with a hammer type of guy and if that does not work, use a bigger hammer. Much the same goes for resistance checks. What I can’t get my head around is why into days world there is not a replacement 12v motor I can fit in. I would think that a lot of power would be lost with the locos old control system. Taking out and fitting in new motors I can do. Understanding what looks like 50 year old units I have not a hope.

19/08/2019 19:26:01

Ron, I think you are right the Sinclair motor is not man enough. I think that this is going to be too much for me to sort out as I am a complete donut when it comes to electronics. Sad to say that there is nothing useful in my location in the way of motor servicing. So I think I will get on with the repaint and eBay it. Thanks for your input.

19/08/2019 17:24:41

Hi chaps, just connected a fully charged battery directly to the motors, no movement at all so looks like both motors are U/S. So the question is. Is it possible to fit a new motor and control unit without breaking the bank, if so what motor and which control system.. Or is it time to past it on to someone with more electronics knowledge and interest then I have.
