May I ask how you cut the foam so you could lay the eyepieces flat instead of up and down? And is there any local retail store that I can get foam from? Did you know how deep to cut like measuring each eyepiece? It looks very amazing and I would like to try this!!

Hi Metanmanstan:

For the rectangular cuts I just use a very sharp, stiff knife like a fishing filet knife and take my time. I cut the rectangular plug all the way through the foam to start with. If I need a hole that is not the full depth, then I cut a slice off the bottom of the plug and put it back in the bottom of the hole.

I couldn't find any local stores for the foam so I bought it online. Links are in my posts above.

Foam remnants, large enough for eyepiece cases are often available at upholstery shops.

:graduate: For vertical eyepiece storage take your eyepieces, load them into a rail gun and blast them through the foam. :bigshock: Perfect holes every time. :waytogo: Remember to fold the eye cups down first. :step:

"Electric carving knives work well for stright cuts. They may even be on sale after thanksgiving..."

They still make and sell them?? :question:
Haven't seen one since I guess the '60's or early '70's!
Never missed the one my mother bought way back when. I'd rather use a "real" knife! :D
Didn't mean to hijack the thread...I'm old. :bawling:

You can get electric carving knives at Walmart for $10 in the kitchen section. I use them for cleaning fish, and they beat heck out of the overpriced Rapalla knives and others that are supposedly made for fishing.

I'm a Woodworker so I carve foam with a Dremel Rotary Tool and Carbide cutters. Very easy to do with a stady hand.

You can also wet your foam and freeze it solid, then work it with regular woodworking tools, drill bits and the like.  This works OK in summer, but the warm tools tend to melt surfaces somewhat quickly, but working in cold weather in an unheated space works really well.  Only real problem is, it might take 3 or 4 days for the foam to dry out once it thaws......

restaurant supply stores carry nested sets of metal cutters of graduated sizes that also work well. freezing is a big plus.
