3M double-sided tape

Setting up a model shop, hell, I wish I was saddled with such a "bummer" project.

Sounds good, doesn't it. Dream job, really.... if you have management support. If you're not fighting them constantly, every time they doubt your competence, every grand that's spent, with no plan, no vision, no budget. The CNC arrived on the loading dock, Jan '07, in time to get accounting another line item of capital expenditure for '07. But, it was almost 6 mos before management decided where to put it and to "make ready". That's just the tip of the iceberg. "The rest of the story" would take volumes that a better man would have quit over. And I've basically given up a design career for this horse manure. Yeah, it's been loads of fun. Hey, it's in Sunny San Diego... I'll send them your Resume (maybe make a couple grand for a referral). My boss keeps saying they're going to hire somebody to do the job. Yeah, sure, once I get them to the place where they can hire a cheap, button pushing zombie. No, forget sending the Resume, you're WAY overqualified.

I've never used an Oi-MC, but I've had good luck with an O-M C just using a default Pro/E post, #12 I think...

I am about to revisit the post processor question. I'll take a look at the output of #12. I know what code I'm looking for. Ideally, I'd be making my own with G-post. Any experience with this? Pointers?

I clean both parts, roll out some of the sheet and sandwich it between my material and the REN, I then heat the material with a propane torch (moving quickly) until the adhesive melts (under 200F) then I set a weight on it until it cools. Your safety committee probably wouldn't like that too much...

I used to do the sandwiching but also applied Kant-Twist clamp. This was especially useful with tape. You could see the effect through Lexan. I think I'm gonna try a Milwaukee heat gun on the Mitee-Grip: no explosion hazard, no cylinders to go empty, better temp control. Although, yeah, I really do like fire! And the little pop it makes when you light it.

The ability to remove something thin without bending it is nice. Down sides are the goop is too thick for extremely tight thickness control in Z, the bond strength isn't that high, and it can leave a residue that needs to be removed (don't try to remove it in a tumbler, mucks up the media).

But Z depths are probably good enough for prototypes. And they are machine accurate from one depth to another on the same operation.

When using an aluminum sacrificial table surface I clean the part with a coolant damp towel, and I clean the fixture with acetone. The glue stays on the fixture, the part usually stays clean. When using REN, I skim it dry and blow it off with air. Again, the glue favors the fresh REN. This is all good stuff.

¡Muchas gracias, Señor!

Well, Mike, we tried those numbers, didn't check out. Can you ask the guy that orders the stuff?

Much appreciated, David Janes

Thanks again. What do you use if for? How well does it work?
