Probably less, if you count sleepy time.

Looks like we have a lot of machinists on FM

Try using a mill file. I believe those are aluminum and would probably foul a bench grinder wheel quickly.

F 'em.

Be glad you are not in Canada. $25 USPS Priority for a flat plate.

I have to ask again, why take an item that holds a good portion of its value used and hack it up so later it has no value at all? seems just a little counterproductive unless it is already damaged in some way.

This. My professor for machining class, who built warships during WWII, told us that the wheel will get loaded up with aluminum which can then expand and tear the wheel apart.

Damn. Some people have too much time. I'd just buy the proper plate.

Mill files are steel. Even forged aluminum is too soft to make files.

Aluminum forms galls on a grinding wheel and the wheel just stops working.
Or send it to Charles Gallo. He has a couple milling machines handy.

Just go to a local machine shop.

NEVER grind aluminum on a grinding wheel. Use a belt sander or files. Or a milling machine if you have access to one and know how to use it. The machine shop is your best bet.

btw, I am a master machinist.

I do not find this to be the case. My L plate for the 1dsII cost around $160 and I sold it for around $55 before I had to pay the post office and paypal. In my experience the plate depreciates like the camera...fast and hard.

+1 ^^

Especially if the plate is for a camera that is discontinued or being phased out. A quick fleabay search tells you this.

was it RRS or Kirk? was it in good shape? these hold their value. if so, then, you sold yourself short. I have been able to sell my plates at a reasonable price every single time. I try to give people their monies worth but I don't give it away. I have no old plates.

oh, any other brands then those two you are on your own.

If one can lightly modify a plate to work with a second version of a camera, then overall I think one ends up ahead. I have not found that used plates get any decent return on selling them, so modification to make them work for me saves a lot of cash. If they were such a valuable commodity, then the resale value would be higher.

I did some milling on my RRS L-bracket for my old 10D body, but for a different reason - I wanted to be able to use a Camdapter hand strap, and there was no strap lug originally.

I'll do anything to keep that old 10D functional, just so I've got something not-too-valuable to keep in the car all the time. I even modified a pair (18-55 IS and 55-250 IS) of modern kit lenses (total cost of $200) to work with it:

I tried a Nikon D40 and their equivalent VR kit lenses, but the 10D output is so much nicer, especially with the improved Adobe LR4.x.

Now back to the original topic . . .

> There is such a small amount that needs to be taken off, I would do it with a "flat bastard" file.

i recently modified a plate with a file. Worked great. I did not have access to a milling machine but it would have been overkill.

Well, this sure turned into an active discussion! Some follow up:

The 5D L plate sells for $50 or less. People just are not looking for them. The 5DmkII L plate sells for $75 and up. I wanted to save some money and do a slight mod and keep it functional. However I realized the 5DmkII has the timer plug in a different position requiring significant modification to get the 5D L plate to work on a mmii. I ultimately bought a standard (non-L) bracket for the mkii and that worked well enough for my trip. I may get a mkII l bracket, when those prices drop also.

I've also realized how many of these I have around: 5D L bracket, 1D standard, 30D standard, long plate for 200-400mm lens, 200 1.8L bracket, and not a 5Dmkii. ANyone need an old bracket? the 200 1.8L bracket comes with a 200 1.8 attached
