Thread: H and F Halogen Lamp

Hi Bob, merry christmas
It took 1 1/2 to fail, and after taking it apart I found the wires corroded that go to the bulb behind the reflector..
All the one's mounted on the machines at H&F's are mounted vertical, this might help it be more stable. Factory fitted ones don't have 2 arms like your only a single arm so you will have more reach.
If you remove the 3 screws at the front then the nut at the back you can get behind the reflector to see the wiring. I found on mine it was steel wire not copper.
I have found them to be robust enough, they have plastic washers between the joints for friction.

G'day Dave,

The side mount isn't working in my favour but there was nowhere else that I wanted to mount it.

Phillip "Metalman" has his lamp attached to the horizontal tee slot incorporated in the head of his 13. His lamp is a lot lighter than the H&F and I did not want to court disaster with a similar mounting.

The reach is good. I can swing the lamp around in front of the head. Certainly beats using a Dolphin torch to illuminate the workings!

The steel wire is a nice touch. Novel way of keeping the cost down.

Regards
Bob.

You could use the same 2 bolts but with a piece of angle to come out horizontal to mount it on. This is the way factory ones are mounted and they have a hole in centre of the angle for the cord.

Dave

Dave,

The flat plate was something I had laying around. I was toying with the idea of something far more complicated featuring a quick release mechanism that would facilitate mounting the lamp on other machines but, laziness and a desire to see the lamp working prevailed.

Mounting the foot vertically is something that I will look at. It may remove some of the strain from that bottom pivot.

Bob.

Dave,

While it's still relevant and I'm still sober I rigged up the lamp base to sit on an angle vertically. This isn't going to work because the arms get tangled in both the coolant hose and the on-off switch lever.

I will tackle the task of improving the bottom joint.

Back to the Becks.

Bob.

Hi,
The problem with all these L/V Halogen lamps is the extreem heat they run at. Too hot for copper and the insulation can't take it since asbestos is a no no. The first 2" behind the bulb just cooks, even using 200oc wire.

It's looking like I should have asked Santa for a different toy.

They are handy, I wouldn't be with out mine. Can you put it on top of the ram? that way it would have free movement to almost anywhere and clear everything.
If not what about the other side?

Dave

I have three of these and love them. Now two of them run long duty cycles, they are mounted on mine and my wife's bed side tables as reading lamps. yes they can get hot, but the lamps can be down rated if you want.

The third my wife bought for me last week to mount on the new lathe, and it makes a real difference compared to the puny unit that come with the lathe.

It took I think 4 years to kill the lamp in our reading lamps, and they both went within a week of each other. If can cover the price premium, we use blue lamps to get some color correction for the reading lamps, (day light color temp) which is color matched to the lamps in my study for judging photographic prints under a standard light. We find it easier on the eyes. I would not bother for the workshop.

Dave,

You are going to say "mount the thing in the tee slot" and that's why I've included a photo of the slot. The casting is about 4mm thick above the slot. It's already crowded and will be more so when I make a suitable attachment for mounting a dial indicator above the slot.

Below the horizontal head, there's the variable speed control hand wheel and the hi-lo gear selector. Busier than the other side. The top of the horizontal head is curved. I will persevere with the current location.

Bob.

Thanks for that Tony.

Bob.

Dave,

I'm thinking now about a modified bracket that's hinged, and lockable, to enable horizontal, vertical and anything in between mounting. Shouldn't be too hard.

Same right hand mounting location which requires no modification to the machine.

Bob.

Going buy the photo's above I wasn't sure what was up top or on the other side, but with these pictures I see it would be a bit hard.
