Sorry. I understood what you said in the past. Thank you for clarifying/confirming.
BTW I never tried bending a razor blade before. Hell, there might be some ideal (perfect) angle for the ultimate cut lap result. Maybe I should heat it with a propane torch before bending. I ain't no pro.
But this sounds like the opposite of what you posted in an earlier thread:
[quote="$1"] ... then fold the tape all the way up and cut from underneath the foam . This way you are not cutting toward the foam ... [/quote]

sorry for my lashing earlier...
there is no specific angle to the bent blade, just bend the backbone of the blade and you will get a curve to the blade. this will give you just enough angle to lay the blade flat on the cutline.
what Ogre stated doesnt sound completely correct but I know what he meens, cutting above the foam not into the foam, blade flat to the surface.
thanks G Rat
I have my moments
A bit of bend in the blade will help to keep from scoring the foam, and even then be careful. Cheap Chinese razor blades snap and do not bend. Bent razor blades help when trimming b-stage ding repairs too, as to not score the substrate; the late great Paul McKinney taught me that one, but I bet he wouldn’t use the term substrate.
As they say, “A picture is worth a thousand words:”
Glassers call that a zipper or shingle cut. But I have to add that’s not the best placement of your index finger in the second picture.
by 69 my glassers were doing zippers and the word said it all
pics look ok but hands in wrong place? and indicate a slow process when you do this day inn and day out
it is a natural cut ziiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiip

ha ha you guys are super critical! I have never once cut my fingers doing this… and the epoxy was still a bit soft but I was out of time for the day because I was at Ray’s place, my son was with me and wanted to go home, so I was cutting a bit early, and it was going slowly because of that…as you know if the resin isn’t quite ready it doesnt’ make that nice zippy sound, (and you can’t cut as fast either).
Also I dont always do the vertical cuts in the tape but sometimes its a helpful trick to find the edge of the tape …particularly if you haven’t done many cutlaps before.
Anybody who does this for a living, please post up a picture or three of you doing it with your fingers in the right place!! I am not a pro glasser but my cutlaps do come out nice and clean and tidy, even if it takes me an extra 3 or 4 minutes.
cheers from the lower tech lab where its all good fun!
Hi,
I want to do a cutlap on my next board. I will use a fully tinted epoxy on the deck. But I am wondering, will I see the tape line through the tinted epoxy? I have the epoxy 101 by Greg Loehr it’s a great tool, but he freelaps the tinted board, bummer!
For example this picture, how does one see the edge of tape? Is it still visible? Do you have to lift to see the edge? I don’t want to glass and find out there’s no way to find the tape!
Sounds silly but someone told me to use a flashlight. Shine it from under the board and you can see the tape edge. It works! even with very dark opague colors.
That could work, if not my board had a solid wooden deck and rails …
I might just try it and see how it works.
