This is new to me, although it isn't very groundbreaking it may have a lot of room for improvement.

What sort of resin are you referring to? "Resin" could mean nearly anything. Epoxies are resins.

Also, Devcon is a brand. I say this because I casually refer to "Devcon" or "Devconning something" a lot, and I am usually referring to Plastic Welder methacrylate or equivalent product. That "Devcon" is not very brittle, not that it would work to cast things.

Apologies, I was rather generic.  For my actual casting, I use this:  http://www.amazon.com/Environmental-Technology-16-Ounce-Casting-Craft/dp/B000GBT8V0/ref=sr_1_1?ie=UTF8&qid=1368544117&sr=8-1&keywords=easycast+resin

And the Devcon epoxy that SGNerf and others have used to cast, but has been found to be rather brittle, is this stuff.  http://www.acehardware.com/product/index.jsp?productId=1382310&cagpspn=pla&CAWELAID=344292287

Has anyone successfully cast gears with a mold like that?

Back a long while, SGnerf was on about casting parts with Devcon steel-filled epoxy. If you could get an accurate enough mold and get a clean pull without any bubbles or flaws (disaster in a gear), that stuff could do the job.

I've been able to cast a slip-clutch before and successfully used it, and it was much smaller than the Stampede main gear.  I wouldn't recommend using Devcon or JB Weld, it's far too brittle.  Resin is excellent for the application.

On the Hammershot:  it looks like it is severely lacking in power.  Look at the darts curve even at that short of a distance....
If you need to replace some of the larger Stampede gears, it is possible to make a mold of it using two-part silicone casting compound and then cast your own gears with resin.  It's not hard, and whenever you break it, make a new one. 

Also, Toruk, I hereby challenge you to make this thing run on electric at some stage. Because if you can, it will be awesome.

With the massive priming stroke this thing has, you're going to have to run a ridiculous amount of voltage through it to get a decent ROF....

Doubled my dart shingle capacity today.  I'm getting ready for some NIC wars this summer....

I know this isn't a major interest of the members here, but it certainly is a useful technique.
Made up a few homemade 45-degree PVC bends for use in choppers.

Question for Elite Alpha trooper owners:

My problem with the blaster is the prime, its not too heavy or difficult by any means but its not smooth at all. It seems to catch against something every time I go to pull it all the way back.

The Question:

Has anyone opened up their Elite Alpha and solved the problem to smoothing the prime on your blaster?

I actually had this problem with one of my Troopers.  There is a mechanical lock that keeps the bolt sled in the halfway position if you do not prime it all the way, and I discovered that it was causing that rather rough prime.  There are a pair of teeth on the right side of the boltsled (looking down the bolt from the plunger end) that engage the lock.  Take that stupid lock out.  Also, if you take out all of the other locks, it makes it much more user friendly to someone who knows what they are doing.

Very slick. I like the whole heavy motif you've got going on what with the punisher and all. Oh and in my opinion? (Not that you asked for it) that thing is absolutely screaming for about another 15psi and threaded 19 shot absolver shells.

Thank you, but it definitely needs some cleaning up before it's battle-worthy.  Opinions here are always welcome (in my opinion)  I had forgotten entrely about absolver shells.....it definitely is a good candidate for that, with the on-board compressor.  The compressor I have now can go up to 100 psi, but without a gauge or OPV I don't want to push my pressure limits.  It could definitely reach absolver-worthy pressures, right now I'm just letting it run for 10 seconds then shutting it off.
EDIT:  I just tried this thing with an 18 inch SCH 80 barrel and a standard slug, and I have no idea where it went, but I do know it went through 4 consecutive layers of cardboard...... I can't wait to get a Mongo breech set up with this thing.
EDIT to avoid double post:
I made a crap ton of darts today.  The EAT is just for size reference.

A little something I built today because I wanted to have a better rocket launcher.  It's ghetto and fugly, but certainly does its job.

Based off of a design by the mod man, but with a few additions.  First is an on board battery and compressor.  Secondly, I like my stock better.
Not sure what kind of pressures I'm working with right now, but I'm guessing 35 PSI or less.  The rocket is going at least 100 feet flat.

The Punisher uses a worm screw for its dart pusher and I've never had a problem with it.

I've gotta say after taking the AR out of my first Trooper, the darts fly visibly faster and hit louder.  Totally worth it, as well as getting all those damned locks out of the system.

Grabbed 2 at the $5.98 price.  Thanks for the heads up.

Just got 2 Elite ATs for $5.98 each. I think it's cause of the old ATs having the same DCPI numbers so when they went on clearance and stopped being sold, these new ATs got that prices affixed to them.

At target?

Finished product:
