These look more like light leaks to me: bromide drag will flow from the highlights in the image, these seem to be coming from specific places on the camera.
The varicontrol is for a 12v point source bulb. The output voltage is to low for the 212 bulb. The 212 bulb will cover 4x5 if it is positioned properly.
Given the amount of disassembly here, it looks like you will need to tension the springs: be very careful doing this, because the springs are extremely powerful. Hopefully, you will have gotten this...

FWIW, I believe that the foam ring on the inside of the rotating back is supposed to press against the back of the bellows frame. If this seals properly, it shouldn't matter whether light gets in...
Correct -- I have the 180mm Componon S in shutter. The end of the rear element also screws into a Durst LAPLA.
I was taken aside after they scanned my Wista 4x5 in a carry-on backpack at the Kona, HI airport. They asked for instructions as to how to unpack the backpack, but then asked me to unfold the...
Sounds good. FWIW, I do my dodging and burning with the timer as well, but the "dodge" foot switch is still handy for things like focusing and setting up filters where you want the light on for a...
I use this timer with both foot switches. The "start" switch starts the timer (as if the red button had been pressed). The "dodge" switch turns on the enlarger lamp as long as the switch is held...
myLightMeter Pro is also nice.
+1 for the 240mm f/9 Fujinon A, especially close up.
Yes, there should be a mixing box. It basically fills the inside of the head with a 45-degree slope opposite where the bulbs project inwards. Mine looks like it is lined with something akin to...
FWIW, I found that Nyogel focus damping grease works admirably in place of the automotive moly grease he recommends...

I use F-stop calculator from Jefro Studio on iOS 10.
Wollensak made a 210mm f/6.8 Raptar.
I've used an adapter like this: http://www.g4leds.com/led-light-accessories/lamp-holder-converter-adapter-to-convert-e26e27-to-mr16mr11g4g635.html
with various 12v bulbs successfully. No...
Also, if anyone ends up buying (or has bought) a Densichron, I would greatly appreciate a PDF scan of any manuals, instructions, or other paperwork that comes with it -- information is scarce on...
docw asked in a PM about equipment for measuring light fall off. My response went over the 2000-character limit, so I'll put the bulk of it here for posterity:
I used a Welch Densichron for my...
Hopefully my last post on this:
I went back to the 300w Thorn bulb and tested again using the diffuser-tipped probe. The results were rather surprising:
4x5 300w Thorn: (09, .08, .07, .08) =...
Here's another set of readings using the translucent-tipped probe. Using it on the G40, I can trace a relatively smooth gradation from the center of the negative carrier to the corners (no...
FWIW, I found a probe tip this morning with a built-in diffuser that seems to give more stable readings in the corners. I'll try again with it and report back.
Ok, I repeated my measurements with 3 different light sources. This time, I elevated the far side of the probe by 1 inch to get rid of the shadow cast by the probe aperture, which I think was...
Yes, Luis, I have a G40 bulb at home -- I'll give it a try. I'll also try the cold-light head for comparison.
Note that when I say "negative" above, I mean "negative carrier" -- I didn't have a...
So, in the interest of "science", I took some measurements off my enlarger using a photometer to compare a 300w Thorn bulb with a PH212 bulb. I zeroed the photometer to the center of the negative,...
I've never had illumination issues using the smaller 211/212/213 bulbs for 4x5 if the bulb position is properly adjusted. There is less margin of error for this than with the larger Thorn bulbs (so...
The PH211/212/213 bulbs work fine on the L138 (with increased contrast). Less than $5 at B&H.
Thanks Jason -- I do like the idea of using the auxiliary standard to support the front. This should make the sagging a non-issue when I have the space in my bag. When traveling light, it's hard to...
My solution to the tragic Norma lens hood incompatibility issue:

The secret ingredient is a pair of 25mm M4 brass hex spacers designed to mount motherboards to computer cases. These are...
Copal 0 shutters will also screw directly into the LAPLA 32.
I use the readily-available PH211/212/213 bulbs in my 138 all the time with no obvious ill effects. The inherent contrast is maybe a grade higher than the larger Thorn bulbs due to the increased...
I use one with my enlarger from time to time. Native contrast is lower than with the condenser head, which is often nice for portraits. I normally prefer the condenser head, so it's nice to be able...
I also have a Victorian home with unlevel floors, so to fix the wobbliness, I bolted the enlarger to the wall. You can use the holes in the legs for bolts once you take off the wheels. The top of...
IIRC, I was able to use a SETOPLA for 50mm on the L1000. LATUB/SEIMAR is overkill. SEIPLA should also work. LAPLA isn't recessed enough. I have never seen a TAUPLA, even in a photo...

I would /not/ recommend laying the enlarger on its side. Bolt it to the wall or leave it alone.

You can buy a Variac (= AC variable transformer) off the evil auction site that will supply 24v from household current. You'll need to rewire your color head with a standard 3-prong plug so that it...
