First time gluing experience

This user has no status.
I used DHS No. 15. Put two layers on the rubbers. The cutting is where I ran into problems. I should have used a paper cutter. The scissors just weren’t good enough. Any advice anyone can give me on how to cut DHS rubbers?

I should mention that the blue sponge is a bit beyond the edges of the blade and can be trimmed further. Should I do it?

Finally, someone who cuts rubbers worse than I do LOL.

Getting some good scissors or a scalpel will help. The blue sponge is tough so you will need to cut, move, cut, move. Some softer sponges you can almost just glide through.

The H3 sponge was too dense. I should have used something with a less dense sponge for my first cutting. The 8-80 was a lot easier though. Also,
Can you please elaborate on the cut move thing?
Im going to get a paper cutter and trim the blue sponge tonight.

If you cut with scissors, it can be hard to glide forward and cut the blue sponge, you will probably need to jam it tight against the edge and deflect the scissor arm to cut, then move forward. In some softer sponges you can do it simultaneously and smoothly. So I suggest to make small cuts when cutting blue sponge and go slowly.

Trimming after is more difficult, but you can make it work. Beware that the legal limit is 2mm sticking out.

I will try trimming tonight. I only play casually so I don’t think the legal limit will be a problem. I am also going to measure it to check how far its sticking out.

Buy a pair of small tailoring scissors - they will comfortably cut through hard sponges and it will be fairly easy to have a neat finish.

I do it with a lot of short snips without fully closing them and gently curving around the edge of the blade as I go. I deliberately leave about a 1mm gap rather than trying to make it perfectly flush.

I’ll try and find some. Tt scissors are 3k INR here so hella expensive. Craft knives are more easily found. Tailoring scissors ill have to look for.

Moisturizing the scalpel blade will reduce friction and you will have easy cutting. I am lazy and most of the time use small scissors. The bonus of scissors is that they leave additional 1mm rubber on all sides. That can compensate for future shrinkage. But there are some tricky parts:

1. Maintain small pressure in the direction of the rubber surface just to reduce the chance of separation.

2. Maintain small pressure toward the cut.

3. Make small movements with the scissors. Cut 1mm at a time.

For regluing I use 2 pieces of baking paper between the blade and the rubber. The small one covers the lower part of the rubber, 20mm above the handle. When the rubber is positioned correctly, I remove the small piece of paper and press the rubber. After that, I remove the bigger piece of paper and press the rest of the rubber with a roller. For soft, thin or sticky rubbers, I put a paper sheet between the roller and the surface. If the rubber is bent too much during the pressing, it will stretch and after removal will be shorter.
