THE METAL RISER (PICS)

[shapeshifter]

it is still very rough but the brunt of the milling is complete (i still have to mill the holes for the mathews harmonic dampeners). now i have to grind the final profile both back and belly, round off all the sharp edges, sand it down and then get some color to it. this riser will accept both my recurve and hybrid limbs through the use of interchangable limb pads that have the correct limb pad angles (i'll include some pics of them the next time i post). in the pics you can see some elongated ovals that are machined at an angle on the sides of the riser...... they are .020 deep and will hold exotic wood inlays (veneers). the reason that they are not in the grip section is because the grip will be glued up with matching accent stripes. sorry that the pics are so poor, with or without the flash there is so much reflection that you really cant see the detail in it. i am hoping to be shooting it by the end of the weekend or early next week (still have some limbs to lay up). i have completely redesigned the limb pads since i started this one. the next riser will have have pivoting limb pads that will ride on ball bearings so that i can adjust tiller and change limb pad angles with just the twist of the limb bolt but still have the ultra tight fit/zero limb slop that this system has. the grip section will also have a 15 degree cant versus the vertical one that this has.

I can't wait to see it done because it's the best one I have seen so far(IMHO). I am not a metal riser type of guy but this look good. Looks great<><

nice.....great work

[thp]

Man, that is really cool.  Impressive metal working.  
That is the cyborg robot monster of traditional bows! Watch out DAS and Hoyt!  Keep up the good work.

Gino has some good ideas thats for sure.

Dase looks good, I mean dose

Rico- that is funny (LMAO) but you still misspelled "does".......unless you are spelling it with that New York accent (hehe). the next one will be radically different but i figured for a newbie machinist like me, the simple design of the DAS (incorporated with the geopmetry of my bows) would give me less headaches to mill out. bill howland and i were joking around and said that this one would be called the BAS ("B" for bruno) and be pronounced "boss" since my limbs outperform the fita limbs by such a large margin.

[HalfRack]

Nicely done! Was it designed in 2D or 3D? Was it machined manual or CNC? I'd like to try this at some point too, but have too much development of limbs left to even think about trying now.

Very interesting and a nice job, looks like it is way past centershot.

what kind of metal are you using for the riser/ why does it look gold????? aluminum?

[shapeshifter]

halfrack- it was done on my manual mill (see the "pretty riser material?" thread there are some pics of it being cut).

bue- thanks! it is .40 past center

ironrhino- it is T-6 6061 aluminum (the next one will be titanium). it looks gold in some of the pics when the flash was off on the camera. because of the machining marks, it reflects the light really bad and i was having troubles betting some pics.

[shapeshifter]

i have had a bunch of people ask how long the riser is so i figured i would post a few pics of it next to a couple of my "in progress" wood riser (they just have the first 3 coats of gloss to start filling in the pores of the wood so they are not purdy yet. the leopardwood bow still has to have the glass limb pads trimmed off). the aluminum riser is 15 1/4" and with the recurve limb pads on will be 17" (for a 58" bow)overall. the hybrid limb pads make the riser 15 1/2" (64" bow).

I am a Mechanical Engineer in a Tool & Die shop and I have to tell you if you did all of that on a manual mill that is impressive.  As soon as I seen your pics I started thinking about drawing that in the 3D software and programming that for our CNC's.  That is fantastic.  You are quite the metal worker.  Keep up the good work.  If you ever want a 3D model of that and don't have the means to do so let me know I would be willing to draw that up for ya and get you some blue prints.

tim- thanks! all done on my manual mill.....it took a while especially since this is the first time i have every machined a piece of metal this size!

[Talondale]

Seeing the wooden models are you going to raise the heel of the metal riser with the wooden grips when you add them?  Your wooden risers have a high heel and the metal is straight grip.

[shapeshifter]

Talondale- the grips will be nearly identical other than the fact that i can make the throat of the grip much smaller because of the strength of the aluminum.

SS,

Impressive !!

Seeing how I can't draw two straight lines without a ruler!

This is the last straw...I have had it with this site. We got people making unbelieveable knives, call boxes, bows, arrows, all kinds of leatherwork and now this?  What kind of people are you???????...oh yea the answer is ...unbelievably talented.

Thats pretty cool. We have an endmill at work and I've thought of trying something like this. can't wait to see the finishe product.
