An attempt at improving a H and F Lamp.
I have never been overly fond of my halogen machine lamp. I thought that I had an excuse to rid myself of it when Greg told me of a Waldmann lamp he had seen on French Ebay. I won the auction then the seller informed me that the advertised shipping was incorrect and that shipping would cost an additional 70 Euros. I jumped ship.
My main frustration with the H & F lamp is the need to use a pair of spanners to adjust the tension in the joints and to lock them in place. The manner in which I have mounted the lamp to the mill hasn't helped matters. I know Philip "Metalman" has a much lighter task lamp mounted in the horizontal tee slot on the horizontal head of his Schaublin but the H & F lamp is heavy and ungainly and certainly not worth risking damage to the mill if mounted in a similar fashion.
I had a star handled M10 screw I had bought years ago from Carbatec as a replacement for the blade tensioning screw on a 14 inch bandsaw. I had never used it because the original screw was imperial. The plastic handle was the right size for what I had in mind and fortunately Carbatec had another to match. I reduced the diameter of the screw and cut an M8 thread by hand. This was to replace the bolt at the joint.
The nut was a bit more of a puzzle. I deliberated over a number of weird and wonderful ideas before I came up with today's simple answer. I bit of 5mm flat bar, tapped and fitted with a pair of locating dowels.
Works OK. Definitely beats ginning around with spanners. The lamp remains awkward.

p.s. There was another Waldmann lamp on French Ebay. It had a pair of 24 volt fluorescent lamps. My concern was whether lamps of that size and voltage would be available here or would I be throwing money at a citron.

Hi BT,
I've got the same worklight on my mill, the globe went a few weeks back, or so I thought, when I pulled it apart I found the globe was fine, but, the wire to the globe socket had corroded through the crimped eyelet. I had some ceramic halogen globe holders which fitted ok, and replaced the wiring with high temperature silicon insulated wires.
I like the mods to the adjustment mechanism, I have some of those knobs, I think they came with some t-slot track from carbatec .
Thanks for the idea.
Regards
Ray

Hello Ray,
I have heard of that same corrosion problem occuring on other similar halogen lamps. Would the replacement high temperature silicon insulated wire be avaliable from a seller like Jaycar?

Hi BT,
If you need to change the wiring, see if you can get a ceramic socket with the high temperature wires already crimped to the sockets.
Like this one.
That image is from Ceramic Halogen Lamp Holder, 12V transformers Available to Purchase Online at LIGHTING Pro Australia

PS Now we are throwing money at a lemon..

I had the same problem of the light going out on my mill and I found that the contacts and the springs in the socket were very soft and misshapen,probably from heat caused by bad contact. I eventually solved the problem by cutting up some of that terminal strip which has opaque nylon insulation and using the brass pieces with the two screws to connect the wires directly to the pins on the globe. So far so good.
