damn Rev im sorry i missed this i got the silicone sheet and tubing from McMasterCarr.com the sheet was like a 2" X 6" piece about a 1/4" thick. i believe the highest working temp with this stuff is 600deg. this should be taken into consideration when choosing a temp to start/heat up the hakko before its first use. but with my hakko i set the dial around 5 or 6 hundy and its ready to use within a minute. i dont remember the tubing size exactly, but i do remember when first getting it the DBV HC fit VERY tightly so i thought i would need to re-order a dif size w/ larger ID. but after some fiddling i got it to slide in and that fucker isnt going anywhere. since then ive removed it and re-installed numerous times and its perfect. ive got some others who are asking me to put one of these together for them. ive told them a couple times now that if they just buy the actual soldering station that they wouldnt have to make a temp dimmer/dial, but they insist that i make it so im going to. im going to try to convert as many of my friends to vaping as i can. im also working on (loosely) a new all glass air path heater cover that will mate perfectly with a hakko iron. ive got an idea that im certain will work, but i need to get its specs and everything ironed out and then have a glassblower make it. im actually very happy with how this idea is coming along. it will attach to the hakko using the stock hakko nut/flange set-up. all glass air path and adapters available to cater your HC needs to your bowl. anyone wanna start a vape company?
