Nixon - that is the silicone i just used for my mould, worked a treat and the 275g pack seems to be about right. For shell material I've gone with some water-clear polyester resin i had laying about, that too has worked great, I've just got to smooth off the surface (my silicone mould had...

Thanks for reassuring me a little. I'll be diying the shells (i hope!)

No, an audiologist did them. He said they were reasonably deep, perhaps 'reasonably' isn't as far as the second bend, perhaps the photo doesn't show them right. Hope they'll be ok, really can't afford to go again

Finally got my impressions done.       Will start mold making this weekend   

excellent, thanks very much!

Need to find some of the tubing for the drivers, in the UK ideally.   It's the last thing i need, got my impression appointment booked for tomorrow.   I can find this...

I'll be starting to put my iems together soon, these turned up in the UK from mouser today, ordered sunday, Free FEDEX delivery  with all VAT and Duty paid :D   They are Knowles BK-26824, bought them because they're fairly cheap, bought 4 because i had to get over £50 for the free delivery...

Quote: Thankyou I'm definitely keen not to ruin my professional impressions as i don't want to spend out on those again once done. So i don't want something that will adhere to the (i'm guessing) delicate impressions and then tearing them apart on removal.   I have polyester casting...

I'd love more details of your shell making process.   I've read through this thread 2+ times but there's a lot to absorb and i might have missed your process

I'd like some info on how people are creating their negative molds and finished iem shells?   I guess the negative from an impression needs to be a soft flexible material (latex?) so as to let the impression and any subsequent hard shells out. Are people then filling the negative void with...

nice, thanks, been looking at mouser the last couple of days, good to hear from someone in my situation

Quote: that would be great, i am just embarking on this journey and you're right, the information is very dispersed regarding what people have accomplished and it what way.

Thankyou, i will contact them!

are the covers removable?   I'm wondering because you can get some pretty small countersunk screws, it'd be great to get back into the shell again

Been reading up on the amazing efforts of the many diy iem builders here and definitely feel like giving it a go.   Got my impression appointment booked for next week and think i've figured out what i'm going to do about cables, jacks and removable connectors, etc...     So far i'm...
