I am moving all of my Skate Bike posts to my new website SkateBike.org

What started as a few posts on restoring my 1980’s Minson has grown to a collection of photos, reference materials and videos on skatebikes and how to restore them. Dedicated collectors keep giving me more details to add and I needed a dedicated site where I could reorganize everything.

We’ve got it all: Minson, Roller Shuttle, Twisties Edition, Garel Monocycle, LeRun and Max Skatebike. A large collection of commercials, ads and video of riders and their skatebikes. Also lots of technical articles on restoring a skatebike including diagrams, dimensions and part numbers.

Do you know this rider from 50 years ago?

Richard Helms was a Clarion State College student from Pittsburgh in 1970 when he snapped a photograph that recently won recognition. “I originally shot this as a Kodachrome slide,” Helms told the CLARION NEWS in an email exchange. Helms said he was sorting through his old slides earlier this year and found the snowmobile shot.

“I entered it and was selected to show in the SPARK Photo Themed Juried Show,” Helms said. “The theme was ‘Motion.’ I recently found out I won honorable mention.” Helms graduated from Clarion State College in August of 1971 and moved to Canada to do graduate work in computer research and development.

As for the photograph, Helms doesn’t know who the rider is and believes the race was held somewhere near Shippenville.

“In 1970 there was a snowmobile turf race,” Helms recalled. “For those not familiar with turf racing, in the 60s and early 70s, snowmobiles were air-cooled and used a bogie wheel suspension. Later sleds required snow as a lubricant and to aid in cooling, but the old sleds ran just fine on grass. Arctic Cat even came out with a limited production of grass racers called the Arctic Cat Turf Tiger.”

If anyone knows the identity of the snowmobile driver, drop us a line at the CLARION NEWS.

Clarion Turf Racing Photo Wins Honourable Mention

Today my photo “Clarion Turf Racing” won the honourable mention at the SPARK Photo Festival Themed Juried Show. The theme this year was “Motion.” I originally shot this as a Kodachrome slide in 1970 at a race in Clarion, PA with a Russian Zenit-E 35mm camera.

The Zenit-E was just about the most manual camera ever. You even had to manually close the iris before pressing the shutter. I found the slide a few years ago while scanning with a slide scanner. It could scan with high enough resolution to print at 11×17 at 300 dpi in 48 bit colour. With photoshop I could pull out the detail and colours as well as clean up dust and such. When I heard the theme was “motion,” I immediately thought of this race.

I am so honoured to receive an Honourable Mention. I am privileged to be included in such a remarkable group of photographers.

Mentos in Diet Coke

Did the classic Mentos in a bottle of Diet Coke for the grandkids. Dropped about 6 Mentos in. The video was shot with an iPhone 11 at 1080P 240 fps slow-motion. I thought it worked rather well. Diet Coke was used so there is no sugar mess left.

SPARK Themed Juried Exhibit 2020 – Clarion Turf Racing

Received exciting news yesterday. I have been accepted into the SPARK Photo Festival Themed Juried Show. The theme this year is “Motion.” I originally shot this as a Kodachrome slide in 1970 at a race in Clarion, PA with a Russian Zenit-E 35mm camera. Last year I was scanning my slides and discovered these. Many hours later in Photoshop the image was ready to enter.

For those not familiar with turf racing, in the 60’s and early 70’s snowmobiles were air cooled and used a bogie wheel suspension. Later sleds required snow as a lubricant and to aid in cooling, but the old sleds ran just fine on grass. Arctic Cat even came out with a limited production of grass racers called the Arctic Cat Turf Tiger.

202 entries were received for the juried show and 25 selected. All entries had to be 11×17″ or 17×11″ and the selected works are printed and framed by SPARK. I am looking forward to the reception on April 3, 2020.

Two other interesting shots from the event was the appearance of the Arctic Cat Boss Cat. It held the world speed record for a snowmobile of 125.87 mph.

Rich Helms’ Farewell When He Left IBM in 1997

Paper Mache – Distressing the Teeth

Now that I had a technique for making teeth, it was time to do some mass production. The picture above is of 28 teeth: formed, sanded, smoothed, gessoed, base coated and first layer of distressing applied. I want the teeth to look old so I have been investigating how to distress them.

I still need a few more layers to build up the antiquing look.

And this is ONLY the lower jaw. I still have another 28 to make for the top.

Paper Mache: Types of Glue – White vs Wood

When I started into paper mache I tried several types of glue but quickly choose traditional white resin glue as my favourite. I surfed for more details but one question intrigued me: white vs wood glue.

Weldbond, Wood and White glues

Weldbond, Wood and White glues

For my work I use three glues.

  1. “White glue” or “hobby and craft” – polyvinyl acetate (PVA)
  2. “Carpenter’s glue” or “wood glue” or “yellow glue” – aliphatic resin emulsion
  3. “Weldbond” – a brand of glue by FT Ross

Other than Weldbond, I tend to use generic or house brands of white and carpenter’s glue. Here are my observations of each as it pertains to paper mache.

First thing I learned is all white glues are not the same. Some are thicker and made to grab and dry faster. For paper mache you want the basic white glue. I buy it in three litre jugs and fill smaller dispensers. In the image above, the left dispenser with the crazy top is white glue, the right is carpenter glue. I found a four pack of these pictured small squeeze bottles in an art store. I drill a hole in the top then make come sort of cap. Then I fill them as needed.

The small bottle of white glue called “Craft Glue” is an example of a thicker, faster drying glue. I found it too thick for most of my work and tough to control the flow of glue when dispersing in a thin line.

Latch Bail Jar

Latch Bail Jar

For paper mache glue I use a latch bail jar. Easy to mix up a new batch (90% white glue, 10% water), quick to open and close. It is important to keep the jar closed when not using it to avoid dried chunks. I usually apply my glue with long flat brushes.

Let’s walk through the three for strengths and weaknesses.

White Glue

  • Easiest to find. Cheap.
  • Mixes with water for paper mache. I run 10-25% water depending on what I am doing. 10% water is my most common recipe.
  • Flexible when dry.
  • NOT SANDABLE. Clogs up the sand paper.
  • Will not chip. Of you have a drip or clump off of the side it is not easy to break off.
  • Softens when exposed to water.

Carpenter’s Glue

  • Easy to find.
  • Use full strength.
  • Sandable when dry.
  • NOT flexible. It cracks when bent.
  • Chips off if you have drips off to the side.
  • Resists water.
  • I use when gluing wood parts together such as a tongue depressor to a dowel. The drips out the side chip off easily and you can sand the edges of the bond.

Weldbond

  • Use full strength.
  • Great for gluing an object to paper mache. Dries fast, strong bond.
  • Closes small gaps nicely.
  • Shrinks when dried.
  • Resists water.

So what’s the best glue for paper mache? For me it is all of them. They each have a purpose.

Paper Mache: Trying Teeth in Pottie Mouth

Not that I had a technique for making teeth, it was time to make some and try them on the jaw.

Tooth Forming Jig

I created nine teeth and attached a short length of bamboo skewer to the bottom. This will serve as the root when putting them into the jar as well as a way to stand them up while painting. I took a board and just drilled a few rows of holes.

Lessons Learned

  1. The toilet seat needed to be sanded. The finish is designed to resist staining so it also resists paints and glue. I wish I had sanded the seat before attaching anything like the gullet. Removing 8 screws and the two parts would have been free and easier to work on.
  2. Next time I am going to drill into the base of the tooth with a drill press to make the hole centred and straight. It is hard to hand drill into them.
  3. The depressors sitting in water last about 3 days then they start to fall apart. 

Now that I see how they work, I will start on the side ones shortening them towards the back of the jaw.

This is definitely fun.

Steps to form a tooth

After much experimenting I have come up with the approach I am using for Pottie Mouth's teeth. As I learn more I will modify this post to reflect what I learn.

  1. Start with a $9 box of 500 unsterilized 3/4" x 6" tongue depressors
  2. Soak a few depressors overnight in water Jun 17 - I tried just boiling dry depressors and it worked fine so I no longer presoak.
  3. BOIL them in water for 5 minutes - What I do is put the depressors in a pot with water. Then I bring it to a full rolling boil and turn the burner off. Then I let it sit for 10 minutes.
    The boiling weakens the hard wood's lignin bond, which makes them pliable
  4. Return them to the jar with water.
  5. Remove one from the water and towel dry the surface.
    This prevents diluting the glue
  6. Select a cut piece of 5/8" dowel
  7. Cut off the rounded end of the depressor so that it will be flush with the dowel
  8. Cut the sides to form sharp tooth
  9. Add Wood Glue (not white glue) to the depressor where dowel will join
    Wood glue is sand-able when dry, white glue is not
  10. Place a piece of wet tongue depressor below between the clamp and the tooth. This acts as a guard against the clamp marking the tooth.
  11. Tighten host clamp over end
    By placing a piece of hose or popsicle sticks over depressor you can minimize damage from the tight clamp
  12. Place in the jig
  13. Let dry
    It needs to be bone dry. Exposing to a fan or air flow helps speed the process
  14. Remove from jig, remove clamp
  15. Sand any glue clumps or rough areas
  16. Fill in side between the depressor and dowel with a mixture of Sheetrock 20 and acrylic paint
  17. Paint balance of tooth

June 15. I love tuning a process as I work. Today I decided to use an end of wet tongue depressor to protect the tooth from the clamp.
I added step 10 to put a piece of wet depressor between the clamp and the tooth. I also predrilled the dowel so that I can arrange them on my tooth stand.

Tooth Variations

I made several variations of teeth. Here are some of them.

Seven variations on making teeth

Seven variations on making teeth

  • 7 - This is one of the originals. Note the use of a square cut 1/2" dowel and marks on the face from the hose clamps.
  • 6, 5, 4 - These show the tooth front of variations on 7 where I tried building a transition on the back with paper mache. The problem is the paper on the front hurts the appearance of the tooth. The backs shown below aren't very appealing either.
  • 1 - This is a 5/8" dowel with a sloped cut at top. The clamp marks have been minimized with a piece of hose
  • 3 - The side is just painted. White glue was used so the extra clumps of glue could not be sanded or removed
  • 2 - The side is filled in with acrylic paint thickened up with some Sheetrock 20. Sheetrock is a sandable drywall compound. The 20 means that mixed with water it will harden in 20 minutes. You can also get 5 and 90. As most of my drying is dependant on the drying of the paint, 20 was a good compromise
