I am trying to fix a Magnarc (Type F), the negative feed manual control knob has broken off at the insulator section.I have a spare one which I can put in but am having trouble removing the tapered pins as I do not have an appropriate tool.
Is there an 'easy' way to do this, maybe disconnect it from the clutch end? or should I persevere with my hammer and old nail? I am worried about hitting it too hard and breaking something else.
And what actually does that large magnet do?
Any help greatly appreciated.
Paul

You should use a V block to remove the taper pins or a C-Clamp to slowly pressure in a small nail to force the pin out.
The large magnet is to stabilize the arc and keep the core gasses concetrated in the crater or the positive carbon.

Sears used to sell "pin punches" which are made for the job. While these are available at most any machine tool supply house, I mention Sears because they will probably sell them singly. If you are going to do much work on these old jewels you might even want to buy the set. They really aren't very expensive and will last you a whole lot longer than the nails. I just looked at a recent Enco brochure and found an import set for $5.95.Gordon's comment re the "Vee" block is well advised unless that pin comes out easily. You can substitute anything that has a little weight and with a hole for the pin to go into. Someone else to hold it is almost mandatory.

Hello thanks for the help.
That C clamp idea was excellent and I am kicking myself for not thinking of it.
I ended up taking the whole negative assembly out which made things heaps easier.
Bye Paul

Aren't these things great? Peerless lamps definitely get my prize for "best-looking piece of cinema equipment." They just don't make stuff that looks this good anymore.

In the early 60's zies sold a verticle XenoBlock conversion useing the Xensol III block that fitted the peerless and it included a new glas for the Top with ZiesXenoblock etched in it
It was supplied in both the metal framed and the edgeless one
Strong did much the same when they brought out the X16

Hey Paul, How are they going?
I agree that the top glass thing is pretty cool, but the rest of the body is not so pleasing...couldn't they have used some other colour?

A movie memorabilia collector who visited the booth a while back offered $50. each for the 2 cut glass Peerless logos if I would remove them & get them to him. Tempting I guess, but he was shown the door. If they're ever missing we'll know where to look though.

FrankLooks like you missed out on the $50 each for the 2 glass bits.
One is fully operational but I haven't wired it in yet, the other is missing a couple of vital parts, I may need to come and visit you for spares if no one else has shown interest in them.

Looks like that glass was from a Type G, not F (F's, if I recall, had their glasses in a complete frame). I ran a beloved pair of Gs for about 6 years and still miss 'em.If I can ever get one of those glasses it will occupy a place of honour in my home theare.

Good catch--the glass in the picture is on a type "J" magnarc. I took the picture over the summer at the Cape Cinema (see the picture warehouse...I sent Brad some more pics of the place that he will hopefully put up soon.)This was a surprisingly difficult thing to photograph. I think the exposure was about 1/15th or 1/30th of a second at f/3.5 on 200asa film. (Yes, John, it was Kodak film!)
I wouldn't mind having such a piece of glass, either, but I'm not about to spend $50 on same.

Scott: Thanks for using Kodak film 
. The higher speed stocks would allow a shorter exposure time for great "grab shots" like this in older theatres. I've had great luck with MAX 800 (telephoto shots at figure skating shows) and MAX 400 for my "regular" photos:

My figure-skating fan daughter posted many of the photos we took at recent ice shows on her website:
