who was working on the modern 3d printable Wild Willy's slotted pump?

[bored383]

curious about the outcomes

I'll second that curiosity.

I am going to bump this because I am curious about it, and with the old board being murdered lost track of who was doing it

That was me. JonM made some changes to his model for me in late January, and I took the chance to have it Shapeways printed in their “versatile plastic” SLS.
I got it, then....2020 happened.
It looks and feels great. I just haven’t had the time/gumption to run a 12 gram through it. I was planning on posting a review/results, then get Don back his original handle that he so generously loaned me. Sorry Don, I will PM you to get your address again. The one I had in messages got nuked with the rest of MCB 2.0.
So...a mini review:
Tolerances look good all around. The slot actuates the bolt properly. The Nylon 12 feels plenty strong. The inner dimension slides easily over the body. If anything, I would tighten the body diameter and the width of the lower frame slot just a bit more to take out the little twisting that happens as the bolt knob cams through the cocking motion. Sand paper would take care it if you took it too far. I would also lengthen the rear wings past the bolt slot. Not specifically to give more strength, but to lengthen to as long as possible where the handle interfaces with both the top feed tube and the trigger frame.
On my Nelspot, It just needs a little sanding along the upper slot because it is dragging on the spot welded top tube attachment rails. It will be an easy fix, and actually the gap may be spot on for most Nelspots. Mine have a bit of a bulge in the rail between the spot welds, but I don’t know if that is common.
Here is the only photo I have of it on.

The Shapeways link that JonM sent me is still active it looks like. I just put one in the cart to check. I will check with him if it is ok to post the purchase page link.

I like that short change.

I like that short change.

Thanks. With the trigger shoe it works quite well. Just needs a spring of some sort to keep lever so the plunger is in the “down” position through the whole time from breaking the seal on the old cartridge to puncturing the next. Especially with the extra weight of the trigger shoe making the lever be more of a pendulum, movement of the gun can make the plunger not be fully retracted, which keeps (or prevents) the cartridge face to clear the lip of the pierce cup. Currently, I catch the lever with my little finger during the whole upside down Shaky-Shaky to prevent it.

Honestly, I am really surprised no one on MCB has recreated the Short Change lever. It doesn’t seem that hard compared to much of what we see on here.
With the revival of the Dropout Battle Grip copy development, it sure seems like the logical next step.

Thanks. ...[Snip]...

Or just a good old fashioned speedwheel for the nelspot!

Here are more views of the new design.



I was wrong about where I had it printed. It was i.Materialize.
I got it quoted by 3 services. You can see that it was half the cost compared to Shapeways.



Here are views of the Wild Willy pump handle that Bored383 sent me. At the time, I only had my Nelson Mutt to test it on. I will get some new pictures on a Nelspot.









Here are photos of the only other “Wild Willy” pump I have seen in the wild. Bored383 says he has one like this also. You can see it is much more refined than the one I borrowed. Also below is an APG review/ad for the Wild Willy. It also looks much more refined (but still probably produced from some common grey electrical PVC), than the one I have, which leads me to believe that Don’s shorter one is a hand hacked prototype, or a homemade copy.

This seems like a good time to bring this one back.

[bored383]

yes, let's bring this one back

[ReconSWS]

I will be releasing a 'makers set' of Nelspot STLs and source CAD files over the weekend, similar to the Metadyne thread but a bit more professional. It'll have the files for the front-pump grip with all the internals modeled for a smooth pump action and good tolerance, then ya just mod it how you want put a slot here, texture there, whatever. Stay tuned..

[The Great Equalizer]

Where would I find those files?
