Overweight but still love 'er.
Planned on making myself a deflex/reflex around 45# - 50# and 66NTN. The gods were frowning and it came in at 57#!!! Not sure just what happened. It's charcoal actionwood riser with Osage accents along with white phenolic.

Re: Overweight but still love 'er.
Very nice indeed Bob, great colors, bummer about the extra pounds. Are you still going to keep it?

Re: Overweight but still love 'er.
Bob, you are certainly putting some work into the handles, I am partial to the charcoal Actionwood, what is it like to work with?
I was building a bow for stock and wanted something around 55 to 60 lbs. Calculated the core thickness from previous records and to my surprise the bow came in at 48 lbs.
The vertical bamboo board was from a new box and I think a different manufacturer to my previous supplies.
The bow can sit on the rack waiting for a buyer.

Yep Rob just going do bit extra trapping and bring it down a bit.
Daryl, the charcoal actionwood is quite good to work with, but care is needed as it is susceptible to imbuing its colour onto the phenolic when sanding. [one direction too] Only downfall I find. Funny you mention about the 'boo as this one came from a new box too.Go figure!.Actually the handle work is probably not quite as laborious as it might seem. The I beam does not go right through to the ramp overlays in one piece as it appears . It is just a standard 1 1/2''x 2'' block with the I beam running through centre .Once I do it I then cut the curve to the form. Once the lams and glass are glued up the ramp overlays are cut from the off cut from the curve and centered to match the I beam.

Re: Overweight but still love 'er.
Very very nice lines Bob.
I agree with Darryl, the Grey Actionwood is very nice.
Great job.
Cheers

Re: Overweight but still love 'er.
Looking good Bob,i like working with the actionwood and diamondwood
Re: Overweight but still love 'er.
i' m starting to like it too Rod except for the small issue I mentioned with Daryl about the sanding dust smearing into the phenolic. It is good to work and obviously has plenty of appeal, though I still like the real warmth of actual timber like our native species.

Re: Overweight but still love 'er.
Very nice Bob. On the subject of colours, that Osage is outstanding. Would be good to know if it stays that bright over time. I have heard it will darken up, but I guess it has a lot to do with UV exposure etc.... That is one stunning bow, I'd be tempted to keep it for that special hunting trip when you don't have to draw it 100+ time per day, it looks to have good "mojo" to me.
Cheers.... Rod
Cheers.... Rod
Re: Overweight but still love 'er.
Tthanks Rod. Truth is the Osage will definitely darken. Left in the sun it will go a deep brown colour, which will still look good against the charcoal. Took it on our club for few arrows. didn't have any with spine that really matched, but it punches out an arrow.I intend to take it to trad shoots to demonstrate my bows, but it does have a blemish at the spliced chevrons on each limb. Purely cosmetic but does take a little away from the overall appeal.

Re: Overweight but still love 'er.
Great looking bow. Where do you source the actionwood/stratabond? I can only find overseas suppliers. Are there any Australian suppliers?
Re: Overweight but still love 'er.
Damo , all my glass, phenolic, and Actionwood etc comes from a US supplier. My glue[smooth on] I source from John Mc [Amso 128 here] with the falling dollar its getting painful too!

Re: Overweight but still love 'er.
Here's a force /draw curve I plotted for this bow. I did hope to include some chrono speeds but for some reason, overcast day or what my chrono refuses to give a reading. I'd say it would be similar to previous ones in the 180FPS range with a 9g per inch amo shaft. for some reason too, the damn scanner did a crummy job of scanning but I think you can read it ok. It is a very smooth bow to draw and sure hits where your looking!

Re: Overweight but still love 'er.
tried another scan of F/d curve, might be easier to see.Still cant get chrono speeds. I've got to shoot through our carport to use it and the minister for War and finance 's car is in the way!Big hassle to move too as we have a drive way that must be about 55 deg.

Re: Overweight but still love 'er.
Hi Bob, not used to working with grains per inch but if my maths is correct an arrow of 28" AMO length at 9 grains per inch converts to 4.5818 grains per pound of draw weight.bigbob wrote:I'd say it would be similar to previous ones in the 180FPS range with a 9g per inch amo shaft.

Hi Daryl.
9x28=252, 252/55=4.5818.

Re: Overweight but still love 'er.
Ok Ok you two leave me alone!
Another case of putting mouth [ finger] into gear before engaging brain! How about 9 grains per pound of draw length.This is what happens if you are chronically sleep deprived.!
I will endeavor to get some chrono speeds next week when the missus is out so I can use the carport.

57# bow @ 28" draw 47# bow @ 28" draw
It looks like we need to make one bow of a "reference" design to "put into stock" each time we open a new box of boo floor boards. Seems OK but I only make small amounts and haven't sold one yet and am not looking for a market either, but it won't be hard to find someone interested I guess.
Is it possible that very stiff timbers compared to less stiff timbers in the riser deflect a little less in the thin fadeout area (say the first inch or so) resulting in a lot less resistance to bending? My fades are on the neutral axis of the limb so the difference should be immeasurable (outside the fade outs the glass back and belly are doing nearly 90% of the work and the outer 2 lams are doing 90% of the remaining work, with the inner 2 lams under nearly no stress, at least as far as what I can understand)!
Sorry for the thread piracy Bob
