Down...

How long is this gonna take, Buggys-Boy?

Folks diss on slow bows, but hey would you rather get smacked with a baseball going 100mph or a bowling ball going 50mph?

So, if one were hit by each simultaneously from each side which way would you fall? 🤔

I think thats pretty obvious. A baseball player rarely falls down after being hit by an errant pitch.

Considering I move like a glacier, I'll probably melt before I get it done

You would fall down, doesn’t matter which side you fall on once on the ground. 
Learned that from a few Bar fights while getting smacked in the head from two sides at the same time.!!!,
Read between the lines and you’ll get the moral of the story. !!!lol

I was getting frustrated using the gizmo on the round, skinny belly, and I had an idea.......

Here it is, Gizmo V2 or the Gizmod;

Its 9/16" wide and the hole is stepped for a very tight friction fit of the marker. The narrow width is so much easier to keep on the spine of the belly and the marker does not wear away and change the depth of indication.

[Roy from Pa]

Make a gizmo like this boy:)

When I use a Gizmo on a rounded belly I don't just use it down the center of the limb but also alone both sides of the belly. It also shows limb twist doing it this way.

[Buggs]

My first thought was also a "V" groove or concave contact surface, but I quickly realized with a mock up that as the limb widened, it lost contact with the belly.

[Roy from Pa]

If ya would lay off the Tequila before ya work on a bow, the Gizmo might track down the center of a rounded belly. 

[Buggs]

How did you know I like Tequilla?

[Roy from Pa]

Good guess:)

Why do you guys use those gismos for tillering anyway? Something wrong with yer eyeballs?

With selfbows the Gizmo is a big help because of the irregularities with staves.

Gizmo, it no lie. Plus it keeps you from getting too rambunctious and removing too much too fast. For me that is a big plus!

[Buggs]

Had to step away from this for a while. There are a few challenges with a bow that has to be pre-tillered and I needed to think on it, rather than just go for it. The lams I am using all have grain runout in two directions and were never meant to be drawn with out glass backing. Makes it difficult to put any bend into it without fear of a fracture or explosion!

This is as far as I dare bend it unglassed

Thats 6", about brace height. When a quarter turn of the Gizmo marker is the difference between no markings and a continuous line on the limb, the limit has been reached.
I put a little reflex into it at glue up and am pleased to see that it has retained 1/4". Thought that would have pulled out by now. I think the round, fat Osage belly has something to do with that.

Now I need to sand this blank smooth as glass so I can slip the braided sleeve over without snagging!

Good to see this build-along back in motion! 

[Buggs]

Thanks onetone, this is partially your fault now

Sanded the crap out of it yesterday, down to 400. I have not done a lot with Osage, always have a challenge with the stuff. I had to be careful sanding, or the Osage would stain the Maple! As I was sanding, I was thinking about coloring the Tiger stripe and I did mess around with a bunch of dyes. In the end I decided it might not be worth doing a three step process, especially not knowing how ugly its going to be with the sleeve, or even if it going to work! I ended up just doing a wipe with washing soda, gives it a little age. You can see its like a sun tan, compared to some untouched Maple

The other thing I have been thinking on, is how to press the epoxy soaked sleeve onto the bow?
I could pull the sleeve real tight and leave it open to the air, but it would have to be on a spit to keep the epoxy from sagging
I have some heat shrink tape which would work, but its 1" wide and there is no way I'm going to spiral wrap 6' of bow with 1/2" overlap. Plus I would still need the spit to spiral wrap.
I also have some antique shrink wrap left over from my wife's retail business, but I could not get it to suck up tight enough before it started to melt. Pallet wrap would probably work, but I cant get a small quantity.
Then I had the light bulb moment!

 
Heat shrink tube. Its thin wall polyolefin, so epoxy won't stick. It shrinks 2/1 so I need two sizes and unfortunately my supply house only had the 3/4" in stock. Hopefully the 1.5" will be here soon

[Kirkll]

Why mess with the epoxy sleeve at all?…. Just use the heat shrink tubing, and call er good!   

I’ll be interested to see what kind of draw weight you get out of this thing Buggs…
Id bet she’s going to be seriously heavy.

What kind of draw weight have you got targeted?
