Overhead Router

[cadas]

Hi

Can anyone help?

I've aquired a wadkin overhead router, but when it was delivered the 'frequency changer' was disconnected, there are two cables, a three wire cable going to the motor head and a six wire cable going to the control unit.

I've had one go, the frequency changer starts (can't tell if it is going the right way, but I get nothing at the head motor.

I'm guessing the head motor is a DC unit so I am a bit reluctant to keep swopping wires around incase I cause any damage.

Thanks

Welcome to the forum!


I am sure one of the experts will be along soon.
Have you done a Google search at all?

Cheers

Hi

Thanks. I've tried googling for days.

I'm hoping it is something daft, like swop the wires around on the head til it goes but it would help if someone has done this before

Thanks

Hi Cadas, welcome to the forum.

Hi Cadas,

One thing that might - or might not - help is a wiring diagram in section 3.6 of the manual (PDF) (assuming of course that it's a UX). I think though that it show more conductors than you described for the frequency changer.

If not, Scrit will probably be able to advise although I understand his PC is out of commission at the moment.

There are some diagrams here.

Hi, thanks for the replies.

The manual looks like it is for a slightly later model of router, but that said, the F series it refers to looks like it shares a lot of the same components. Mine looks like this www.kestreldevelopments.co.uk/RAREngineering/Router.html

In the touble shooting section it suggests that if the frequency changer starts but the head doesn't then the problem is likely to be with the switching sequence.

So I gues that means trial and error on the connections until something moves.

Hi, all sorted, only took two attempts (ie change wires, plug in and then push apprentice towards start button with long stick)

Does anyone have a manual for one of these, there are a couple of adjustment knobs that I still can't identify

Thanks for all the replies

OK, looks like I guessed the wrong machine when I posted the manual above. I think from your photo it's more likely that you have an LS router, whose manual is available here.

Cheers

EDIT: There's a list of Wadkin and Wadkin-Bursgreen manuals available for free download here

Perfect, thanks

For anyone interested all the British-built frequency changer driven pin routers I've come across (for the Record that's White MU, Interwood OF/OFN, Sagar ACJ9 and Wadkin LS/LE/UXF/URF as well as the Rye automatic shapers) use AC spindles. In fact the early UXs share the same changer as the LS/LE routers. In later years this was a Brook unit (early ones were apparently BTH, Brook Motors predecessor company), whilst the original spindles came from Lancashire Dynamo on Trafford Park, now long gone.

The output from the mechanically driven frequency changer on British units requires 6 cables from the switch gear (high and low speeds - LS/LE types were generally supplied in 12,000/18,000 rpm configuration, hence the doubled-up set of cables) and three cables to the spindle motor.
