Magazine Housing - Part 2

Time to create: 2 hours
Cost of materials: €0.00

 

So, here we are, all glued up with JB Weld and sanded. As the substrate was quite thin, I wanted more visual thickness and added some adhesive-backed 2mm craft foam to the inside. This will also provide the compression fit I want for the magazine.

Next I turned to the top button. I noticed that tinner's rivets have a concentric swirl pattern on top so I shopped that rivet around until I found a wash the right diameter with a perfect sized hole for the rivet. I didn't document this part because I was too busy feeling inspired and just working on it. I made a sandwich with two washers and some JB Weld and placed the rivet in the center and then sawed a groove in the top. In the end, I epoxied it to a spring loaded shaft and mounted the assembly into the housing. It even has a nice little "click" sound. :)

I'm pretty happy with this piece. :) I made a mock-up magazine which fits nicely and started on the aluminum version. That will have to wait until my next update though and I'm going on holiday for a few weeks so it'll be a while... but I'll be back.

That looks really good, Michael. The only thing I would suggest, is to replace the grub screw with a bigger one (M6 is a nice fit).

After much self-deliberation, I decided to add the knurling as Tino suggested. I didn't want to do it, I wanted to move on but in the end, Kev's words kept haunting me. :)

I have a habit of haunting people, and that's before I die...

 

the force? oh I'll use the force, bring me a hammer...

Thanks! I had all the pieces in my random bits of stuff in the shop and it came together effortlessly which made it really fun.  :)

It's probably time for an update... :)

I've actually finished the blaster but I'll continue to add to this thread because it's kinda cool to look back and see how far it came.

 

Selector Switch

 

Time to create: 1/2 hour
Cost of materials: €0.05

 

Using Zeroroom's patterns, I cut the switch from scrap 2mm aluminum.

A little filing and sanding...

Having created the front sight guard and knurling, I was emboldened to try other ways of transferring the knurled pattern to my materials...

Very nice, Michael. Loving your detailed work - and the tutorial-like posting style.

 

Hoping we don't have to wait another 4 months for the next update?! ;)

That's fair. I deserve that. 

 

I swear, on my white armor, that you will not have to wait four more months. :)

Pistol Grip Frame

 

Time to create: 3 1/2 hours
Cost of materials: €2.50

 

This part looks simple but I wanted it to be stronger so I used 2mm aluminum which is much more difficult with which to work that the thinner material I used on the magazine housing.

First the pattern was shot with spray glue and adhered to the metal, then I clamped it in the vise and began cutting with a jeweler's saw.

This was a lot of work and I broke several blades but it was worth it to cut a close as possible to minimize the finishing work.

Then the usual filing and sanding to the final shape.

 

I punched the hole for the locking locating pin using my handy-dandy punch and voilà we're done. Oh yeah, don't forget to make two. ;)

Something I didn't illustrate here was the bend along the top edge. I scored the aluminum with a utility knife and carefully bent the edge to create a flange which matched the curve of the barrel and would later attach to it. That took better than an hour to complete.

Great work on this project so far!   I'm loving the whole idea of making everything from scratch.

 

I've never seen a hand punch that could punch metal like that before, I'm going to have to try to find one to add to my tool kit!

Thanks Jon!

 

The punch is a Roper Whitney No. 5 Jr style hand punch. It exerts over a ton of force and can punch up to 16ga cold rolled steel. I use it for any rigid sheet material that needs a hole or two.
