I like making micarta but it sure is messy!
I'm going to make some for one of the projects I have on the go. Thanks for the tutorial. It's a good starting point for me
see if this works....
Works good! That is a very clean process.
Great work and tutorial Dan. love the full flat grind and scales.
I've made My-carta before but the mention of the casting resin just gave me a great idea. I had a request from a co-worker for something in the handle of a knife but I wasn't sure how to go about doing it. Now to order a few things and give it a try. Would the casting resin from a place like Michael's work?
My casting resin I bought from Kidder: http://kidder.ca/clear-polyester-casting-resin-946ml-with-catalyst.html
I think Michael's has something called "Crystal Resin" from Pebeo. Never used it before.
A while back, Icho put a couple of casing heads from bullets into handle with casting resin. Maybe he can say where he got his resin from.
Here is what I used.
I got it at hobby lobby in the US. I am not sure exactly what Michael 's has but I would think any clear casting resin should work.
Here's the link to my attempt
The West Sytem is known for its clearness for high end finish.....and is probably the best epoxy available
Great tutorial Dan. One thing to mention is that sanding micarta, the dust isn't good for you. Or so I have read. My first two attempts, I was plagued with the fuzzies. Not to sure where I went wrong.
Yup, sanding just about anything isn't good for you. Micarta is fabric or paper, so not as brutal as G10 which is glass. Respirator up! G10 gets into the skin too. I learned to wear long sleeves after the first time. It's itchy as hell like insulating the attic.
I need new scales for my ship knife so I'm going to do this during my down time at work this weekend. Great post!
I just finished making some micarta i used cotton and bondo fibreglass resin my results were disappointing it hardened up nice but the micarta is fraying almost pulling layers apart. I used about 420 ml of resin for a piece 6 by 6 inches about half inch thick after it cured piece was quarter inch thick. A lot of resin squeezed out I saturated both sides of cotton and scraped excess off with a putty knife before i put in mold should i have only spread resin on one side only? And i could of squeezed it harder but wasn't sure how hard to go.
I squeezed mine moderately with three C-clamps in wooden form. I made 4 oz (~120 ml) of resin for about a 4" x 12" x 3/8" piece, and it oozed out like crazy. At least I was confident that every layer was saturated.
Do you mean it's "pulling apart" when cutting it into scales?
Can you post a photo?
When I cut some it, there were the odd thread that frayed from the surface layer, but when sanding these disappeared.
I made two batches with the bondo fibreglass. One with jeans and the other with dyed canvas. The canvas turned out better than the jean. Im going to try some with some west system I have and some water clear stuff I bought from the fake flower display section at Walmart. I think I'll try paper this time.
It's important for every layer to be totally saturated... I re-learned this lesson last week when I had to make another block of my-carta because I was a little overzealous cleaning off the excess resin between layers. When cut the whole slab delaminated, I'm not sure if there's any way to save it but as it was made with West Systems 105/207 (the $125 a can stuff) so I sincerely hope so. Had to remake a new slab and made sure I didn't use too little resin. The real kicker is I had a bunch extra on the original slab that I ended up not using for anything because I wasn't ready to do anything else and only have a press set up for one slab at a time.
