2020---->What did ya do today?

[Mad Max]

Video don't werk...

I think I fix it

[mmattockx]

Nice...  You should be doing a build on it's own thread...   

Yes he should.

Nope I don't really know what I'm doing, just moving forward to see what happens

Did you say that with a straight face?

Going to glue on a osage overlay and some buffalo horn for the tips

That looks great. How narrow are the tips at this point?

I have been looking at doing static recurves in a similar fashion because none of the wood I use has been willing to survive tight bends, even after boiling. Making static recurves like your siyahs and then splicing them in solves that problem for me.

Lookin good Mark!! Think the titebond will keep her together?

If the joints are done correctly the TBIII will be as strong as epoxy on those woods. It is only the oily tropical woods like ipe that need epoxy, anything that doesn't repel water will glue fine with TBIII.

How narrow are the tips at this point?
The tip are about 1/2" wide now
.050 will bend with the sitca spruce.

This a glass static recurve using the form below
4" from the nock to the bridge


This is the form I made years ago with a top form and fire hose.

The sitca I have is very dry so I dipped them in water about 5 min. before glueup

1/4" at the tips, the belly is 1/2" wide


Did you say that with a straight face?
It's a bamboo slat with no belly lam except the last 10" out to the siyah.
I have more control with a glass bow, so I'm going to give this a try with the slats.

They look even skinnier. Not at all crazy narrow, plenty of room to work with.

.050 will bend with the sitca spruce.

I meant none of the woods I have will bend into recurves at full thickness of a limb, the way guys bend recurves into osage without a second thought. It's a different story when laminated on a form in many thin strips. That works well for almost all woods. I don't have Sitka spruce available but I do have Lodgepole pine that I am going to try some tests with later into spring. It is slightly heavier than the spruce is, but still a better stiffness to weight ratio than most other hardwoods. Should make a decent static recurve tip.

1/4" at the tips, the belly is 1/2" wide

That is beautiful. Is the peg sticking out both sides for the string to bend over?

Regardless, you still seem to have a good handle on making bows, especially tricky wood ones. That snakey osage was a work of art.

It's called a bridge, like on a horn bow lever (Siyah)

Same style bow with different bridge


Regardless, you still seem to have a good handle on making bows, especially tricky wood ones.
I had plenty that I burned and cut up, so maybe I will get lucky again

[mmattockx]

Any more progress with this bow? I'm looking forward to seeing it braced and drawn.


Lest I be the target of derision for not doing anything myself, over the last few days I have got my form and post pieces all worked out and finished, glued up the core lam pieces into a full length single lam and hopefully will be boiling and forming the belly lams on the riser ramps today. After they dry I should be able to do the first glue up stage of core/belly lams/riser. I guess I should be taking pics of all this for a future thread on the form and bow build...

Pictures please
I wiped off all the tru-oil wif Everclear and going to shoot it wif Epoxy.
Same limb dynamics as this bow

[mmattockx]

Pictures please

You posted some, so that seems fair. I will get some this afternoon if the light is manageable and post them. It won't be anything fancy yet, just a bunch of loose parts and a lam bow 'kit' needing gluing.

That tiller shot shows a very sweet bend, I look forward to seeing it with the laminated handle.

If that exotic work of art does not work out as a bow, I bet you could use it to join a Jug band. It looks like its going to have some twang

what you talkin bout willis

Got some of this.

Turned into some of this.

Looks good Brad.

[Mad Max]

Is that canned deer meat?

I promised pics, so here they are.

First off, the new jig/form:





The spine is a piece of 3 1/2" x 2 1/2" x 1/4" steel angle that I inherited with our place. The posts have a shoulder piece brad nailed to them to set the height at that point. They are not set accurately along the angle iron, just clamped on to show the general idea.

This is forming the belly lams onto the riser ramps after boiling them for 15 minutes:





I think I am going to have to do another boil/forming tomorrow to get the ends formed properly and then let them sit a couple days to dry. After that the glue up starts.

I like how it's adjustable.  Do you use a radiused fixture to clamp the lam in while boiling?

[Roy from Pa]

Very nice..

[Mad Max]

 

[Buemaker]

Looking good.

Yeppers.  With a little garlic salt and some peppers and onions.
