Your a funny bugga Peregrine,

Thanks people, I'll experiment with your suggestions.

Cheers Muz

Have tried Sharpie type ink pens but when applying wipe on poly it removes the writing.

Think I'll try a fine nibbed paint marker

What does everyone else use?????

Cheers Muz

Hey Rod, yeah the carbon is below the back veneer.

0.030" glass on back
0.020" veneer
0.020" carbon
0.020" carbon
2 bamboo cores with 0.003" tapers each
0.020" veneer
and 0.040" glass on belly

Bugga, better luck next time.

Hey Daryl, just what you'd expect from shooting heavier arrows. Bow was quieter. Won't be using the heavy arrows just wanted to see how she performed. Plan on using the 555gn arrow which is a 400 spine gold tip with a 225gn point. Worked out it gives me a 20%FOC so should be a great hunting set-up. ...

Gave the bow a quick tune and it shoots great. Shot a variety of arrow weights through it and reweighed it at 51# @ 31" 620gn arrows came out at 170fps for 12.1grains/Lb 582gn arrow was 175fps at 11.4gn/Lb 555gn arrow was 180fps at 10.88gn/Lb and 454gn arrow was 195fps at 8.9gn/Lb 10.jpg 11.jpg...

After a bit of sanding and then finished.

I knocked up my third bow. Using WA timbers, though the Mallabie I used wasn't 100% dry but I didn't think It would cause to much drama as its super heavy and dense. WRONG...I have been using my oven to cure the wipe on poly and the extra heat has caused the Mallabie to shrink. So I made a few modif...

Impressive......

Cheers Bob. I've actually ordered other stuff from Big Jim before. Will look at his glass.

Thanks Rod

Its probably been asked many times before but where does everyone source there fibreglass strips from?

I'm about to order more 1.5" clear glass and was wondering other than Binghams where else.

Cheers

Cheers for the tip Rob. Definitely right about lessons learnt the hard way. As this is my first ever attempt at any sort of serious wood working its a steep learning curve but its very enjoyable.

Cheers Mate

It will do the job I'm sure Rod. Wouldn't expect the heat trace to draw to much current. If it does use the PID controller to switch a relay and use that for the heat trace. This is what I've used on my oven.

Cheers Muz

Cheers Rod. Was a lot happier with my second attempt. Have started making Number #3. and will be keeping with the thinner limbs and yes a fare bit of taper to get the limbs to flex.

Then I'll need to order more glass as I'll be out. Bugga...

Great work Tyler

very nice

Good job Rod, very neat, compact and robust. Shouldn't get knocked about in that case that's for sure.

Having just started to glue up a laminated riser I have only just come to appreciate the amount of work you must do on your bows to create such beautiful detail pieces of work.

Bloody awesome mate.

Thanks people. Just been shooting it with my 31" draw and I'm happy with the results. Definitely taking it out on foxes.

Just needs some lighter spined arrows. My lightest are 400 spine and weigh 430gn. Even still its fun to shoot.

Cheers Muz

So I glued up my 2nd attempt on the weekend and have all but finished it off, just needs striker plate and some string serving. Its 58" long and came in at 26lb @ 31". I bought some Western Red Cedar which I made into the veneers and used Coconut Palm for the riser and tips. Should be good...

Starting thinking about the twist in the limbs and how lightly I could move them. So I clamped several bows in the vice and measured the sideways movement verses weight. Came up with a rough figure of 10lbs of weight for 30mm of movement at the string groove. So I used these figures and worked my wa...

Thanks Bob, I used 30 thou glass with the 20 thou carbon on the back and 50 thou glass glass on the belly. I had core laminations of 1 x 94 thou tapered at 003 thou, 1 parallel 94 thou and 1 x 74 thou tapered at 003 thou on the belly. The 74 was made to replace the lams with the split in it and I we...

I think my problem is due to the amount of reflex in my design. I should be treating it more like a recurve in the limb design with thinner wider laminations and only tapering towards the tips.Hence why it has taken on so much weight. Maybe.....???????

I shaped the bow today, marked it all out so that it ran from 31mm at the fades out to 15mm at the tips. After a bit of sanding I was close to my marks so I made my temporary nocks at 68" and tired stringing it. I could only just manage it using both hands and then my knee as well. My 80+lb bow...

Had a bit of time tonight so I glued it up. Ended up chucking a parallel core in the mix as well. All was going well until I placed the riser block on top of the stack on the form and turned my back to apply glue to the next stage. The slippery bugger slid off and damaged the feathered fading edges ...

Cheers Rob, yes there's a 20 thou carbon going in there under Jarrah venneers. The riser is a solid piece of Jam wood ( acacia acuminata ). I've used Vertical bamboo bench top laminations tapered to 3 thou for the core. Only using two cores as I'm trying to get around the 35-40#@31" with the ca...

Great work, Very insperational, love the pig

Cheers Bob, I searched the net and liked the Peregrine hybrid longbow by Cari-bow and based my design on that. Used a 1m metal ruler to get my curves and made it a bit longer for my 31" draw length.

Early days yet but enjoying the journey thus far.

Cheers Muz

Well I'm a few steps closer. Redid the hot box with two new element heaters at $18ea and lined it also. Controls nicely and gets up to temp easily. Mounted a air regulator on the hot box and an isolation valve on the form. This is so I can transfer the form around while disconnected from the hose an...
