Another Creation

Hey guys, I got sick of this maze3 in my puter. so I decided to make a simple block, hoping to outperform it by only a little if any. I just want something nice in there.

This is my first block with an o-ring and I would have to say the O-ring groove is successful! Im leaktesting it right now and all is well

the channels are 1/8" and fins are 1/16" in a 7/8" wide total size. The standard 1/2" barbs. There is only one other block with the same material used for the top, and both were made by me. Ill keep that on the DL though and if you know, please keep it to yourself.

First 4 pics are the base being milled. The last 3 are the completed work.




Enjoy

Looks nice! Let us know how it performs.

Looks tight, man I gotta get me a mill. . .

Excellent looking block!

Thanx guys, The top wasnt strong enough, It bowed a little and leaked. Im gonna either make a copper top or put 4 more screws in it or make a new top and seal it with silicone... I gotta decide.

Looks like it'll perform well, Jon. *EDIT* I didn't thoroughly read the first post. sorry.

I sure hope so, but not with the leaking O-ring. I was looking for my silicone to just fill in the groove and seal it up, I couldnt find that so I turned to a more permant solution Marine GOOP

Itll never come off!

Yeah, Its delrin.(maybe thats what you edited out) 1/4" stuff flexes too much for the pressure the O-ring puts on it.

What size groove do you use for your 1/8"(.139") O-rings?

Use at least 3/8" thickness.

It might also help, even though it is more expensive to do so, to put the O-ring groove into the copper. This gives more material/rigidity to the top plate.

You can also increase the number of clamping screws from 4 to 8, and this will decrease the "span" over which the top can flex.

Thats the plan for next time cathar I dont think Ill mess with O-rings and plastic.

The reason I didnt put it in copper this time is because If I messed it up, I would be screwed out of it. And It was the first time making diagonals. I was also using a 1/8" end mill to cut a .16" wide groove. It probably took the same amount of time to cut that one in delrin as just a 1/8" groove in copper.

When this thing is converted to cnc, Ill definately be doing that. plus Ill be able to more than double my feedrates with a higher speed spindle.
