All fired up

[Mad Max]

James Parker got me fired up on these little bows.
I did this one on my own
Turkish Glass Horn bow 43"NTN  6" levers


I snip a picture off the internet and cut out the profile

I draw two lines to keep the scale when zoomed in


I bend a piece of paper to measure from nock to center of riser 21-1/2" to make a ruler

I print a ruler and keep drawing until I get what I want

I've been CAD drawing for 32 years, mostly for the Tool and Die work I did. I love trying to figure out how things work
I hope this turns out

[Mad Max]

I'm going to dye (water base) some veneers today turquoise on some curly Myrtle and wait for them to dry.
My bow room is Dehumidified to 40%, I may go lower until they dry
I will measure them in Grams and maybe Grains before and after dyeing.
I can make the form with 1 piece of plywood 24" x 48" 

[Flem]

Do the limbs not taper in width, or is that a rough CAD drawing?

Looking forward to those seeing those Turquoise lams

You have an accurate grain scale?  I can only get down to 1/10gram

[Mad Max]

Limb taper parallel and taper at the lever
Reload scales

That's got great lines, Max!   Glad to see someone working these up again -- from originals, not some fantasy idea....

[Pat B]

Cool ideas, Mark. James can have that affect on people. 

[Buemaker]

This one will be mucho interesting.

[Mad Max]

Cool ideas, Mark. James can have that affect on people.

Very impressive planning Mark!!!!

[Mad Max]

Very impressive planning Mark!!!!

Just my warped mind at work

[Mad Max]

24 hours they were dry
I glued them to my lams

[Arlo]

So you glued your veneers to the lams prior to lay up?  What's the philosophy behind doing this? and what type of glue did you use? If you don't mind me asking.... Arlo

[Mad Max]

What I wanted to do was glue them on the .050 boo lams with EA-40 and then sand .020 off the veneers side and .010 off the boo side.
the dye did not penetrate the veneers like when I did it years  ago
My stack is .160
2-.030 glass and 2- .050 lams
I wanted a better core thickness.
next time I will use dye in my epoxy mix

[Mad Max]

Dadgummit  The very first measurement I wrote down was 43" NTN and suppose to be 48"
3 looked like  a 8
I got 1" on each side of the form extra, so 45" NTN now

Movin on
The Form is done and I skive jointed the lams together
I made some sanding patterns for the 6" long levers today.
I sanded to the line as close as possible and buttered up that side with EA 40 and clamped it together, Saran wrap to keep it from sticking to the pattern

[Mad Max]

Finished the lever forms and made a test one




I got some kind of strep throat, hope it's not Covid

[Roy from Pa]

Hope all is ok, Mark.

I had a severe sore throat on one side for 4 days from it and cold chills like I never had in my life.....

[Mad Max]

I think it's OK

[Flem]

Thats a great color
It looks like a dark Turquoise in the pic, how did it look wet?

[Mad Max]

It looked much darker when wet.

I ordered some So Slow dye for EA 40 for the next time
