Hi guys,
well for the 4th knife in a row that i have been trying them on i am unable to pin brass or nickel silver bolsters to my blade. I know this is something i am going to feel like a complete idiot for not being able to do and i am embarasssed to ask but i am out of options. This is the process i have been going through to try to attach them
drill holes for pins (usually 1/8") then HT blade
finish knife and get ready to do handles
the area that the bolster is going on i rough up with a 60 grit belt, there are also usually 1/4" weight reduction holes drilled through here
on the bolsters i tap some small holes on the bottom to allow something for the epoxy to grip, i also rough up with some 60grit
mix epoxy and glue one side on, hold down with clamps
i will wait until the next day so the epoxy is set up correctly and then drill the holes through, starting 1 or 2 drill sizes smaller and working my way up to the final size (usually 1/8")
now at this point several of the bolsters have come off but not most
I will then glue the other side and and once set up overnight i will drill it out, again here i have lost several sides while drilling even though i go as slow as my drill can go (around 300rpm) and i have used rem oil to try to reduce heat build up. and i drill smaller pilot holes and step my way up to the correct size bit to reduce pressure.
if everything has held then i will try to drive my pins through. i cut them and rough them up with a 60grit belt and i taper one side that i will be driving through, then coat with epoxy and slowly use a small hammer to drive them through. well i have never made it past this point, everything at least by now has broken off.
Tonight i was trying a brass bolster, the hole i drilled should have given around .001-.002" clearance for the pins , they started fine but once i got to hammering them through the other side pop!! the bolster snapped off!! If i wasnt already going bald i would rip all my hair out i swear, its driving me crazy!!!!
if any one could help me i would love it, im at my wits end! oh and im using Devcon 2ton epoxy
thanks
steve
