Diamond lapping film on edge pro ?

Hello guys,

I built myself a clone of the edge pro to sharpen my knifes. It's doing ok, but I wanted to do better with it. At a jobsite, a fiber optic splicer had some nice diamond lapping film in the 15, 6, 3, 1 and 0,3 or 0,2 micron, can't remember what he told me. He couldn't use them more then on 4 fiber as per their company requirement which leaved them pretty new (6"x6" pad without psa) so he gave me a few as he saw I was interrested in them. Now I built myself some .75" x 6" glass block to put on my edge clone and was wondering what's the best way to fix the lapping film without having some bump that will ruin the flatness. Anyone of you have done this before ?


Thanks for your help!
 
It would defeat the purpose of the hard underlayer and make the lapping filmd work close to a leather strop loaded with paste doesn't it ?
 
I use 'DAP Weldwood Multipurpose Spray Adhesive' to stick sandpaper, or paper used for stropping, to glass or wood. Found it at a Woodcraft store. It can be used as a temporary adhesive, by spraying one surface (back of the paper to be stuck) and waiting 5-10 minutes for it to become dry but tacky. You can then press it to the glass or other hard surface. Holds well, and can be pretty cleanly peeled off and replaced at a later time, as needed.

There are some versions of double-sided tape that aren't foam-backed, and more like regular scotch tape, that might also work for this. I have some 3M 'Scotch Permanent Double Sided Tape' that's 1/2" wide. About 3 mil thickness (0.003"), according to 3M's specs; this is about the same thickness as an ordinary sheet of printer/writing paper. Wouldn't lose much, in terms of maintaining a very firm/hard backing under the diamond film. Due to it's 'permanent' adhesive nature, it may not be as attractive an option for peeling off & replacing as needed.

Thank you for the suggestions. As I cut myself 7 glass piece which are glued to 7 custom base I made I have enough for every size of grit and will only need to remove them once worn out. In the worst case I break one glass I would only need to cut one more which is no brainer. I'll try to find the non-foam 2sided tape it might be an easy way to obtain what I was looking for.
 
Spray adhesive is the way to go. Spray the glass, spray the paper, and it's good for as long as the paper holds up.

Interesting. Can you please elaborate on how you are removing the film? Do you need to use any solvent to peel them off, or afterwards to clean the blank?
Can anyone suggest good PSA diamond films, or pre-cut pieces for standard Edge Pro glass blanks?
 
i would stay away from adhesives and just use some type of clamp on both sides. just pull the film as tight as you can and clamp it down. those black metal clips that are used for clipping paper together that is stacked thicker than a paper clip can do. this will allow you more freedom to change films. you would have to clean the adhesives off between changing films or you could get some buildup that chould lead to high and low spots

This is what I use, it is the 3M 6661X 6x6" diamond lapping film attached with the removable version of the Scotch double sided tape, Cat# 667

On the finer/finest grits, I use little to no pressure and generally a back stroke, so there's not a lot of force against the abrasive..so:

Works great, color optional.

Actually the colour is a good idea, lets you see where it has been applied
 
This is interesting, thanks.
Please elaborate, though: did you use it for attaching abrasive film, or wet/dry paper for sharpening/lapping purposes?
Or, probably just think it should work?
 
Super, fvdk!
Thank you for the responce.
So, I gather you have no problems with replacing the film on the glass blanks, meaning: tape holds well and replacing it is fairly flawless?
What is a good source for purchasing films of different grit sizes in small quantities?
I also wondered if there are ny larger than 6" x 6" area film sizes available for lapping high grid (10,000 - 20,000) stones?
I'm sure your input would be helpful to many: Edge Pro is very popular.
 
I also wondered if this method is really superior to stropping the blades with leather, or some exotic cloths and a diamond spray, or paste?
Which methods you use these days after trying a few and selecting the best?
 
rogerxd45,

Thanks for your input, but I doubt this method could be used with Edge Pro blanks.

Thanks for your input, Obsessed with Edges.
Very interesting. How easy it is peeled off?
Does it need any additional cleaning?
Looking forward for some more info!
And thank you: I think many people would find this information valuable.
If not for use with Edge Pro for sharpening, than for lapping their whetstones with wet/dry sandpaper.

No, absolutely no problems. The tape holds very well and comes of easily without leaving any residue.
I bought the film (3mic and 1 mic) as well as the Scotch tape from a US seller on the big auction site as both are not sold here in the Netherlands.
The 3M diamond lapping is also made in letter size sheets with PSA backing so it should be available in the US.
Wicked Edge and Ken Schwartz also sell strips in smaller quantities I believe.
