Preview Backpacks

Scout Camp 2017

Time to carve: who cares it Scout Camp

Location: Rotary Scout Reservation #rsrbsa

Finishing: TBD

Just a quick preview of a set of backpack slides coming up that are being carved right now while at summer camp with our Troop. Its being carved from a piece of maple I had from another project and you might notice I haven't  cut the slide off the stock yet. This allows for a good hand hold and keeps my hand away from the carving. This slide is one off the Internet and the author wasn't sure where he had found it. Another pack (not shown here) is a Bill Andrews "Slide of the Month" #boyslife from February 1984. The final pack is one of my own design and mimics the pack I use as a youth.

Slide of the Month July - Apollo and LEM

July 2017

Time to design: 2 hours
Time to print: 2 hours (your times may vary
Finishing: 2 hour
Original design: Tinkercad
Original designer: xmbrst
Try it yourself: Mini Apollo Mission

Another in my 3d printed space series, the Apollo mission captured the imagination of many including myself. Today I find it even more impressive considering the computing power of both combine craft was less than a Timex wrist watch today. The fact we could go to the moon, land and return safely is testament to the thousands of folks dedicated to the mission and the astronauts who's quick thinking saved many a mission. For a great set of articles on Apollo 11 mission, check out the NASA webpage

I found a few designs out there but I liked xmbrst design because of the modifications he did to reinforce the LEM legs and to make the rocket nozzles solid which could have been a problem when printing. The funny part is when these were printed, I did have some issue with the Apollo capsule breaking loose when printing and the rocket nozzle on the service module was a bit deformed. Well since I was gluing the parts together, it really didn't matter to me that the capsule's heat shield did not print since you would not be able to see it. As to the rocket nozzle, I used a UV activated glue (like these) as filler and then shaped it with sandpaper.  All the parts were glued together using super glue and I drilled a couple of holes in the back for a wire loop.  I used paint pens and home printed water slide decals to detail the slide.

From old to new: sewing kit

June 2017

Time to make: 1 hours
Boys Life "Slide of the Month"
Sept. 1965, page 64
Original design: Bill Poese

So continuing with the old film can slides here is a simple sewing kit than can be very helpful out on the trail for sewing up a button or a tent. The original design contained buttons, thread, needles, a paper ruler, safety pins, straight pins, a thimble, and a small jackknife.

The plastic film container version

My updated design uses an Altoids Smalls tin. I started by painting the outside white and when dry, I applied a water slide decal I had printed on a printer. Next I attached an aluminum loop to the tin using pop rivets

The contents are essentially the same but there are pre-threaded needles. I did leave out the knife because most Scouts have a jackknife with them or you could use (my dentist shutters) your teeth. I also left out the ruler because, well, who measures.

Slide of the Month June - Celtic Knot

May 2017

Time to set up: 5 days

Time to turn: 45 minutes

Finishing: 2 hours

Designs from: Dan Lecocq

Youtube:  Celtic Knot Pen

Inspired by another hobby, I thought turning a 4 ring Celtic Knot would make a great slide. I made the slide from red maple, white maple, and black walnut and turned it on a lathe. While I would suggest watching the youtube video for the setup, I'll try to describe it here.

I cut a piece of red maple 1.5 x 1.5 x 4 inches as the base wood of the slide. Next I cut some thin pieces of white maple (about 1/16 inch thick) and black walnut (about 1/8 inch thick). I glued the thin strips together, white maple- black walnut-white maple, with some wood glue, clamped the whole length of the sandwiched wood and let it dry overnight. The next day I cut the sandwiched wood 1.5 inch strips. Going back to the red maple, I next labeled each side, with a pencil, the first side with a 1, 2 on the opposite side, 3 to the right side of the first side, and 4 to the left side of the first side. Setting up my table saw with a 30 degree tilt and fence at 1 inch from the blade. The height of the blade was set so the was just a 1/4 inch left after the cut. I moved the fence just a bit so the slot was the width of the sandwiched wood. Using some wood glue, I glued the sandwiched wood into the slot, cut off the excess, clamped and left it overnight to dry. The following day I repeated the cut, gluing, and clamping on side 2. The process was repeated for sides 3 and 4. Twenty-four hours after the final glue up, its time to turn the slide.

While it looks very square and nothing like interconnecting rings, rounding the piece brought the rings out in wonderful spender. When I got the piece to the diameter I wanted, I cut a V cut on ether side of the finish length (approximately 2 inches).  Still on the lathe, I sanded the piece down using some very fine sandpaper. Using a finishing method I learned from pen making, I applied several layers of super glue wet sanding between layers.

Removing it from the lathe, I drilled a 3/4 inch hole down the length of the piece and then carefully cut the slide to size using the V cuts as a guide. Finally I coated the inside of the slide with additional super glue.

Slide of the Month May - Project Gemini

May 2017

Time to design: 2 hours
Time to print: 2 hours (your times may vary Finishing: 1 hour
Original design: autocad123
Original designer: unknown
Try it yourself: Gemini capsule slide

Another slide you can 3D print and paint! Fascinated by the space race as a kid, I watched every launch I could. Project Gemini was a test platform for testing many of the things and maneuvers, like docking,  that would be needed in our quest to land a man on the moon.  It was nicknamed the "Gusmobile"  by fellow astronauts because of Gus Grissom  deep involvement in its design. The design was so versatile and dependable there was going to be a Gemini-B and Big G versions.  The  Gemini-B version that was going to be used by the Air Force for a planned a Manned Orbiting Laboratory (MOL). (Great documentary on it called Astrospies on PBS)

The Big G was to be an extended version of the Gemini-B that would carry 9 man missions

I believe I found the original out at autocad123 and I brought it into tinkercad to scale and modify. (Note: The ring is kind of thin and you might want to enlarge the thickness a bit.) When done with my modifications, the project was imported into Cura to convert it into a printable file with the Ultramaker 2 printer at my local library,  Berkshire Athenaeum, to print. When done priniting, I cleaned up the model with a sharp knife and sandpaper. I painted the model with some white and black spray paint and detailed the windows with paint pens. The lettering and flag where done using water slide paper and a printer.

From Old to New: Fishing Kit

April 2017

Time to make: 1 hours
Boys Life "Slide of the Month"
Sept. 1951, page 37
Original design: E.F.S
...and now for another new part of the blog "From Old to New" were I will attempt to update older neckerchief designs from "Slide of the Month" to updated versions. First off the a film can fishing kit to my versions. I remember my dad having a few of these aluminum 35 mm film cans around the house but by the time I was taking pictures the metal film cans became plastic film cans. (see below)
The can was painted with model paint made for metal and a fly was glued to the front. The slide piece was a piece of aluminum flashing pop riveted to the can and then bent into a loop.  The inside includes fishing line, hooks, sinkers, flies, and a cork for a bobber. It all fits very nicely into the can.

Here is the plastic film can

Updated version

Time to make: 1 hours
Original design: Bill Macfarlane

When thinking about an updated version of this slide, I had a couple of options that came to mind. The first was the Altoids Smalls tin and the second was a contact lens cleaner (see below). Altoids tins of all sizes have been a favorite with hobbyists for a few years now and these make great slides.
I spray painted the outside of the tin white and, once it was dry, I pop riveted a piece of aluminum flashing loop to the back. The fly on the front was printed on white water slide decal film. The insides were also updated with day glow fishing line, a piece of foam rubber for a bobber , and a plastic lure. It also includes sinkers, hooks and flies. The same pieces also fit into the contact lens container.

Forget me Knot - Royal Carrick Bend

April 2017

Time to tie: days

Finishing: none though I might try Mod Podge

Designs from: Clarke Green

Knot Website:Royal Carrick Bend

How did I forget to post this knot with the others? Well my friend Clarke Green posted this neckerchief slide back in the summer of 2014 and it's had me gnashing my teeth for a while. I finally got it one night while staying at a hotel in Springfield, MA. (My apologizes to hotel staff who might have seen me carrying a coil of nylon cord, duct tape, and a utility knife up to my room. Nothing weird going on really.)

The first thing to do is to head over to Clarke's site and find the Royal Carrick Bend infograph. Next cut a good length (five feet is what I used) of nylon or paracord.  Now here is the part that just about drove me crazy, lay out the first weave of the knot. I found it was really hard to follow the pattern because the rope was sliding all over the place as I was trying to tie it. This is where the duct tape came in to play. Using small pieces of the tape, I taped each section down to the table as I worked so it would stay in place but also allowing for me to pass the next level through. Once you have woven the knot twice, pick it up and put the center around something round like a 3/4 inch dowel (or a hotel shampoo bottle) and begin to tighten the knot. Once it is tight it becomes a really intricate looking knot neckerchief.  Cut off the excess cord and fuse it with heat or leave on some tails for frayed ends. On mine, I tied the ends into a carrick bend (not shown) and fused the ends.

 For those of you who have never heard of Clarke Green, his Scoutmaster blog, or the Scoutmaster podcast, you really need to find him on the net! The Scoutmaster's Oracle, the podcast Commissioner and really nice guy, Clarke shares his thoughts, wit, and wisdom weekly to the folks that follow him world-wide. Always happy to answer a question for Scouter, his answers are spot-on relying on his many years of Scouting experience. On his site he shares his wisdom and thoughts on Scoutmastership, gear reviews, highlights some of the best books on Scouting, program ideas, and information on high adventure areas.
