Xtreme Pyro

OK, after doing some research it seems the rollers are 35 durometer rollers. I ordered a pair. If I've made a mistake it's a cheap enough one and easily fixed, but I'm 99% certain they are 35s.

I can confirm they are 35 durometer as well, I asked one of my buddies who owns an actual WASP. Also a typo earlier, I meant to say my tape application roller is actually 20 durometer. If you ordered that in 35 durometer too, it will also work fine.

As for the ball transfers needing to be at an angle, when I built mine I didn't put the block at an angle, even with smaller shells they roll just fine without hitting the housing as long as the shell is centered between the drive rollers (One radius apart). Here's a picture:

The other bearing block looks the same, only it is spring loaded.

EDIT: I will second what pyrosam said about the rollers rusting, I pasted a bunch of shells one night and forgot to WD-40 the rollers and they tarnished up over night i'll be looking to replace them with nylon rollers.

Drive wheels . . . black neoprene, 35 durometer?

Tape application wheel . . . diameter, material, durometer?

For my tape applicator roller i'm using the 20 durometer wheel in black neoprene 1.94" wide. It applies the tape nicely, and sort of forms to the curvature of the shell. It is the four inch diameter wheel.

As far as the drive rollers go, I recommend the 60 durometer. Since they are finned they will still flex quite a bit, 35 would be too soft and possibly screw up your pasting run since the diameter of the drive rollers would be affected from compression 35 durometer is surprisingly soft (think softer than a pencil eraser, even softer since they are finned). The diameter of the drive rollers depends on the motors you use, I use 2" drive rollers on mine to get the full amount of torque out of my steppers for shells up to 8".

I've been following this topic for quite some time, and am very glad to see it has picked up again! I was starting to wonder if you guys had given up, keep at it!

I have done what you all are trying to accomplish, and can say it's not as complicated as it seems. I started this project about 8 months ago, and just recently finished it 2 months ago. I wrote my software in C++, which I recommend since it's not only a very efficient language, but there are plenty of stepper libraries to help get you going (though I recommend you write your own, for something like this). I also eliminated the need for a laptop, by using a Micro controller for all my functions. I have an LCD screen with 4 buttons to change the shell size, and to start / stop the paste run. I've nearly perfected the wrapping pattern on my machine for shells up to 8 inches.

I will be more than happy to answer questions anyone may have.

cheers mark' I have the box section for the main spine and once I've cut and drilled it I can start to build it when i find the t slot frames.
I had a nice email off McMaster Carr when I emailed them about the trouble i had looking on there website' and it said

Due to the complexity of U.S. export regulations, McMaster-Carr accepts international orders only from our established customers. This decision also applies to orders shipping within the United States, because it is based on the final destination of the items. We will not provide a quotation or accept your orders.

I only wanted to look on there website but seeing as there loaded and don't need my money I'll look else were lol.
I've been playing about with the Mach3 CNC Control Software but its way too much for what we need imo.

Bill, i'm not sure where you can order t-slotted extrusion in the UK, but you can order the same exact rollers elsewhere for fairly cheap, I don't reside in the UK but if you check http://www.fairlaneproducts.com you may be able to find a distributor near you.
