Need advise on resin glue please

[willpower]

Hi all,

Am making up some resin glue as bit of an experiment and also because I want to set a flint arrow head into an atlatl dart (will bind as well).

Problem is it doesn't seem to stick that hard and stays quite sticky even once its cooled.

My approximate ratio is pretty much a 50/50 pine resin/ charcoal powder mix with a tad bit of beeswax thrown in.

Anyone suggest what I need to do to harden up mix- add more charcoal powder maybe?

Thanks in advance for any advise

When I used it I only used a small amount of charcoal... maybe 10% or less and didn't bother with the beeswax (because I didn't have any) and it set hard

A guy on a bow forum I use sells the stuff on ebay... http://www.ebay.co.uk/itm/4-pine-pi...Hunting_ShootingSports_ET&hash=item2eb7537e00

I believe he uses the 50/50 ratio of pine resin to hardwood charcoal but also adds plant fibre whatever that is and some bees wax.

I bought some blocks off him a while ago but have not yet used any so cant comment on usage.

to make the mix harder add less charcoal and a bit more resin, also try heating it up a little more to help exspell any moisture and caramelise the mix, when it cools it should be solid...

Hi willpower, at first I had sticky batches and brittle batches but after a few goes it came together and now I just rack of eye it, but if it helps here's my method :- resin from wounded tree

dried animal droppings if it eats grass they'll do, here sheep and rabbit which for some reason go on top of boulders so on a sunny day it's dried for you
or put it in a tin by the fire

here a close up

I use a pedstal and mortar then rubbed through a sive

pedstal and mortar and sive some charcoal

I melt the resin in a stainless (charity shop) tea pot with it's built in strainer and then pour it into a stainless steel pouring jug

with this on a pilot light I add roughly equal ammounts of charcoal and droppings untill the mixture is "jet black" I then stir in a small amount of beeswax I usually make a few batches at one go so pour it into silicone moulds which when cooled it doesn't stick to

I can re-melt these over a pilot light in the pouring jug to either dip a stick in then into cold water then back into the resin mix untill it's built up to the size I want, or I pour it into a bucket of water and mould it into a long roll (but you have to be carefull as it's hot and sticks !)

sorry I can't be more precise but once you've done some it'll all come together

I find mine less brittle with the droppings think of them as the chopped glass mat in glass-fiber
The silicon moulds are great for casting just pine resin or sulphur,

theres a star here in sulphur as well as resin, though I do cast blocks of sulphur in the red mold as well

cheers Danny

Great little tutorial Danny.

A great tutorial!
I have not tried the droppings yet - just char and wax in the resin - and have had good results.... if I get the mix right!

Thanks for that tutorial, the small teapot is a great idea..

Excellent tutorial ... I'd never thought of adding some fiberous material to the mix Thanks for the tip!!

Great tutorial, just out of interest what projects are you using the glues for Danny?

Thanks for the replies guys and that excellent tutorial from Danny. I wonder if I could use human hair to give it that fibrous strength?
