cameron micro drill press 164-7 cord help

[gc210]

hi

I got ahold of a cameron micro drill 164-7, and there is a weird cord situation going on. When I look online the photos of the drill press all have normal cords but this is set-up with a resister? I have no idea what it is. It kinda looks like this part for sale on the cameron site. Sometimes it would get very hot, like burn you immediately hot. Most the time it didn't. I saw today the cord broke. I did not cut it I do not know why it looks like it was.

So does anyone know what the deal is, why it would have a resistor(?), if I can just rewire the drill press with a normal cord?

Thanks for any help. I called Cameron customer service 3 times, left 2 voicemails, and never got a call back!

Take a look at item 25, it may be essential for low speed operation

It sure as hell doesn't belong taped to the side of the cord!

From the parts diag^, it looks like it goes on or in the back of the case, where touching it would be less likely.

Hm well if it’s in the wrong spot that would explain why I don’t see it in photos. The guy I got it from never used it, and got it from another guy in a bulk tool buy.

I bet the drill came with a reostat type speed control that was later replaced in the field with a power resistor. Either the reostat went bad or they used the drill for only one precise speed.

Or they used an internal resistor for speed control and it went bad and they did a hack job by splicing it into the power cord.

I bet you could use a Dremel speed control as a substitute. (I have one if you need one)

P.S. That's a very high end drill press

There is a speed-reducing resistor shown in the parts dia above.

Those are very high end devices. Generally, the chuck is worth more than my entire DP.

It has a switch on the motor for a "high" and "low" speed, and beyond that the speed is mostly controlled by the changing the pulleys. From what I understand.

It is a very nice drill and I am hoping to get it fixed up, unfortunately I have zero tool savvy. I use it for drilling rocks and silver for jewelry making.

Cameron sells a cord that matches the parts number (thank you for the link) so I think I will buy it. There is no photo on the website though so I am not sure if it has a resistor, so I might just buy the resistor as well which also matches the parts number.

The Cameron 164 series was offered at one time with a one speed or two speed motor. It ready is a single speed motor with a power switch that can run the motor with or without the power resistor in series.

You can see the two mounting screws for the power resistor on the back of mine. But they had some odd restrictions in the manual if memory serves on using the low speed setting.

i believe in your case the previous owner got sick of burning the stock power resistors up. So the put a much higher wattage power resistor in series with the power cord.

You show a 23ohm 50w resistor in line with the power cord. That is close enough to 20 ohm difference I see on my drill press. But the stock resistor was about 15 watts judging from the resistor mounting hole spacing if the resistor is mounted at an angle.

Be sure to oil it!

The Cameron drill presses are a bit controversial in our family. I am of the opinion that any drill press that you can hold with one hand counts as 0.2 SDPU (standard drill press units).

My better half contends that a drill press is a drill press regardless of size, and I have TOO MANY OF THEM.

My response is that if she embraced the SDPU concept, I would effectively have less drill presses and she would be less stressed regarding their existence in our house.

She still disagrees.
