Making my own liner material with felt, resin and also cardboard stock!
Liners, also called spacers, are usually made of vulcanized fiber, g10 or micarta and are a great detail and touch of color to any handle. I've always wanted to make my own instead of buying from online supply store because here these stuff is pretty expensive and the color range is very limited (red, blue, green, black and white).
I am super happy with how this project turned out, the felt and resin material feels just like the vulcanized fiber I am used to work with but bow I can have it of any color and thickness I like since felt is super cheap and comes in a very wide range of color and thickness.
The resin I used is the cheapest I was able to find and it's just a basic epoxy resin that comes in two part to be mixed (in my case 5:3 ratio) and cures is just around 24hrs. I'm pretty sure any kind of slow setting epoxy would work great for this application. Maybe it can even be done with polyester resin if you have the process clear and work quickly, still I haven't tried, and for the amount of resin you need for this, slow setting epoxy is probably the way to go! For the couple of batches I did this week I used around 40g of mixed resin for each liner (10 by 15 cm wide) but everytime I had plenty squeeze out so I guess it can be used even less resin.
Adding some colored carboard stock to the felt opens up even more possibilities, it works just as well as felt only and it's just as easy. I can't wait to try more color combinations for my upcoming projects.
The vacuum pump I used is one for food storage, I found it locally for very cheap and I guess any similar to the one I have would work for this job. I think that because the small vacuum pump isn't really making much pressure on the felt compared to clamping or locking in the vise, it's more a convinience to remove air from the plastic bag so there is no chance of trapped air or the bag exploding while clamping. Also, the plastic bag I have don't really stick to the resin, so they are reusable. This one looks similar to the one I have: https://amzn.to/2I9lTZY search for "vaccum food" and you'll find many. (Yes, affiliate link, buy wherever you want).
Index of operation and materials:
0:10 Cutting a piece of felt 10x15 cm
0:30 Measuring and mixing up the epoxy resin by manufacturer instruction
0:56 Placing the felt inside some waxed paper to help releasing (probably not needed with my vacuum bags)
1:05 Adding some resin to the felt, this was too much!
1:17 Placing inside the vacuum bag and taking out the air with the pump
1:39 Clamping between flat and rigid surfaces.
2:08 One day later is ready to remove from the bag
2:20 And trimming with my new shear
2:40 The waxed paper can be peeled off easily
2:28 Secon try with purple felt and two layer of yellow cardboard stock
3:50 More experiments with purple felt and white cardboard stock
After that you can watch how it goes on a handle, the process is just the same as any other handle I made, feel free to check other videos if you are looking for more information about that process! I'll just say the wood I used is teak and the steel 420c.
Thanks a lot for watching, I hope you liked the video!
