Metro Made | Bloodlines Slingshots – Meeting Prince Charles

May 21, 2014. The Prince of Whales visits the shop, I am tasked to present him with a unique gift made in the shop. I am proud to say, I have 2 Metro Grade slingshots in the Royal gift collection.

I call these two slingshots, the Bloodlines, as you see, one is for Prince Charles himself and one for his brand new grandson, George. These had to be unique, classic and well crafted, so I didn’t fool around with an unfamiliar shape, I went with my classic Capuchin side shooter.

My goal for the pattern design is to meld a little bit of Brit with a little bit of Canuck. Using the Union Jack as inspiration, maple, paduak and walnut is utilized to make a slightly modified version of it. Here you can see the laser cut maple as the skinny lines of the Union Jack are formed.

As the each piece of paduak is set in place, the ‘Jack comes to life.


As I said, a little bit of Brit and a little but of Canuck. After dry fitting and making sure all the parts fit, it was time for glue up.

Once the glue was set up, the surface was face sanded to reveal the gestalt pattern of the Union Jack being anchored by a purple heart Canadian Leaf. The paste at the bottom is a bit of ghetto wood filler for some gaps left in the lay up.

On one slingshot, I decided to document the date, the event and the location. Also the Assentworks logo is etched into the handle. On the 2nd slingshot, some Metro Grade branding as well as “George”, for obvious reasons. Another purplehear maple leaf would later fill George’s slingshot’s handle.

Some quick router work on the edges and some final sanding before a couple of coats of sealer.

He asked, “are these catapults?” to which I answered “yes, one for you and one for your grandson, George”. He explained how he used to play with one as a child, good to know.

It was an honour to meet him.





It’s funny to review those photos and look at my face….I can’t make a single serious face even when meeting royalty.

Thanks for reading!

Metro Made | Wasply PFS Slingshot

Been a little while since I’ve posted a Metro Made, so there is no reason why NOT to post one. Fresh from the laser cutter to your workshop, this is a tutorial on how to assemble and finish your Wasply PFS Maker Kit. Don’t have one? You can get yours here: Wasply PFS Maker Kit

In the kit, you’ll have two cores, and two sets of palm swells.

First things first, glue up the core, and two palm swells.


When they are set up, I used a belt sander to start to shape the palm swells. This make life a lot easier later if you take off the bulk of the material first.

Once the swells are partial shaped, time to glue up the swells on the body core.



I used a spindle sander to remove the laser burned wood but this can be done with files and sandpaper.


A round file expands and refines the band grooves.


A few more swipes with a first cut file and the inside of the forks is cleaned up.


The hardest part of the build is shaping the palm swells so they are perfectly round. I used the belt sander again, rotating it like a drum stick. Rasps, files and sandpaper will do the same job.


Using some 100 grit nail files, the palm swell is blended into the core, making a seamless joint.


An optional machining step is to cut some scallops with a big 3″ drum into the finger grip area, but this can be done with a 1/2″ round file.

Now to finish it! A variety of 100 grit, 320 grit foam blocks and a final swipe with some steel wool to prep the surface for clear coat or oil.


The one on the left is one designed by Magpie Slingshots and I replicated it to test out the scale. We worked in collaboration to come to the final design of the Wasply PFS.


After a couple of coats of clear and some light buffing with the wool to get it a more matte finish, the Wasply PFS is done!

Metro Grade Tuff Udder Pouches

When building custom slingshots, there three key areas of focus, the frame, the bands and the pouch. The last one often overlooked but it’s one of the most important parts of the slingshot.

We’d like to introduce the first Metro Grade Tuff Udder pouch: The Big Bertha.

Holding the ammo correctly, catapulting it forward, retaining its shape, these are all features of a good ammo pouch design.

Here’s a quick video of the pouches:

We started with a 1/8″ thick, heavily oiled cow hide and threw it under the laser cutter. The design features a ventilated body for increased speed and reduced weight. A middle hole centers the ammo perfectly for consistent results shot after shot.

The laser cutting left the surface dirty, marred with soot and residue. Since we wanted to wash these pouches with a light detergent to remove the surface oil, the bath also removed the grim.

Tuff Udder Fresh Cut

We wanted to start out Tuff Udder series with the biggest and most versatile one, allowing the slinger to shoot anything from 1/4″ steel balls to big rocks found in the wild.

Just under 3″, the Big Bertha isn’t a small pouch, so it’s ideal for heavier band sets.
