Thread: wing cam for black diamond drill grinder

hello from France,
j had bought a bw90 grinder, but "wing cam" of drill holder is missing.
J need a picture of it , with measurements, if possible.
Thank you for your help
regards
Etienne

You can probably buy a new one faster and probably for less expense than making one.

There's a dealer in New York (state) here that has a good supply of new old-stock parts for Black Diamond drill grinders. You have one of the newer ones, so you can also get parts from Black Diamond here in Massachusetts, though you'll pay more and they are harder to deal with.

Rush Machinery of Rushville NY will be honest with you and tell you if they'll ship to France.

hello Pixman,
thank you for the address.
If you have a Black Diamond, can you take a picture of your wing cam?
After wieving, j can choose if i make it or if j buy at Rush 's shop.
regards

You are going to need more than a photo to make a wing cam. Without a good drawing there is almost no chance to get it correct. The grinder is useless without an accurate wing cam.

Here it is.

hello,
thank you very much, Michael, for your pictures.
Like the third photo, can you photography the other side of the wing cam ? ("flat photo", after removal of handwheel).
Moonlight machine, if the active part of the cam is a part of circle, it seems realistic to make it.
thank you all for your help.

Here are both sides of the wing after I removed the collet and the handwheel:

Thank you Michaelp, pictures ares really perfect.
Moonlight: sure, j'll see Rush's price before making it.
Etienne

hello,
Moonlight; Wing cam alone: 195 $, complete drill holder assy: 575 $, without sending cost to France.
j had bought machine with plated grind 150 euros.
well, well, well.... J 'll try to made wing cam. If the results are no satisfactory, it will be time to buy.
Michael, can you measure 3 dimensions on wing cam for me? lenght (between tips), width (narrow part of the cam), and diameter of screw ("socket set screw") on Wing cam.
thank you for your help.
regards
Etienne

I have a dimensioned drawing of a wing cam for the 1.12" holder. I made one a few years ago. I will see if I can dig it up.

Sorry for the delay.

The length is 4.160". Those two set screws that are sticking out of the back side of the cam are 1/4"-20. As for the narrow part of the cam, you'll have to show me exactly where you want me to measure.

I think I have one of those surplus

Might I interest you in a used Black Diamond master collet holder?



As you may be able to tell it is in less than prefect condition.
Would $50 and shipping work for you?

Make sure it is the correct diameter.....

hello,
Lazz, sure , Jm interested. J need spindle 1"1/8 OD (rep 100228 and draw in spindle 100235, see photo).
can you check ?
Michael, j need narrow part at angle 60 ° of length axe (see photo), thanks.
eKretz J am interested by numerised drawing.
Mebfab, can you complete your proposal?
thank you for your help.
regards
Etienne

Is this close enough?
I have used it on a 90-AB.
#11 is broken and I can not include a #13.


I would like to make sure you notice it has bumped the wheel a couple times in the past...

It's 2.320"

hello,
Lazz, what do you mean with

I can not include a #13.

, what is the problem? J need also a 9./16 collet, if you have...
can you give me the price with sending cost to Cherbourg in France?
Michael, thank you again.
Etienne

I do not own an extra 9/16 collet.... I did talk to a buddy that would sell one for $25. I also spoke with the nice lady at UPS and she said without an address or postal code her best guess would be between $40 and $60.

Which would make the total bill:$115 to $135
$50 for the Wing Cam ( mine)
$25 for the 9/16 collet ( my buddies)
$40 to $60 shipping.
