    Experiment with Vertical Pouring for Pen Tubes

    I decided to experiment around with some vertical tube pouring this evening - Before I had used PVC 3/4' tubing which works perfectly fine but I did not like the idea of not being able to see the colors in the tube or being able to make swirls in the resin and be able to see it. So, I hunted around and tried something a bit new - I got some used syringe tubes (from the Vet for free) which are fairly see thru and they seemed to be a perfect size to pour a few tubes with - 2 tubes will make up a two pc pen which was the only downside rather than one pour and cutting the tube in half - In 2 seperate measuring cups I put 1 drop of amber transtint and 1drop of purple transtint and mixed with the cuttings - 3 of the tubes were poured with redwood bandsaw cuttings (very fine) - 1 tube had just the resin poured
    How will they turn out ? well we will see in the next couple days and ill post - below are the pics

    I too anticipate the results of this.

    Dan, what do you use for the color and do you pour them together to get a swirl or do you poke a toothpick into the mess to create a swirl? This is very interesting and looks doable with my students.

    Ok took the blanks I poured over to the bandsaw and cut the ends on the syringes - then i pinched the outside all around the cylinders with my fingers to help loosen them up form the inside (which was waxed prior to pouring) - then with a small blunt tip pc of steel i tapped them out - broke the end on one of them on accident but it should be ok because I poured it longer to begin with - Next time it would be better to tap them with a small wood dowel - They slide right out easily - see pics below - these are only two color pours and is being done as a test - you can of course use multi colors and other objects if you wish
    They were still a bit tacky though so ill leave them another 24hrs before drilling out the centers - probably why the end broke a little also

    First Pour notes:::: I used transtint dye - 1oz small medicine cups - castin resin - a wood starbucks stir stick - 10cc syringes - and paperclip bent in a swirl to dip into the pouring to slowly twirl to move the colors in and out of eachother in the tubes - I learned that one drop in one oz is alot and will really darken your resin - Redwood cuttings mixed in

    Second pour notes (this evening) - I did not use any wood shavings - just resin colored with transtint dye and I put the drops in by dipping my wooden stick into the dye on a paper plate - adding it in slowly and stiring in the 1 oz cup - stir slowly or you will get air bubbles in it

    Ill update again tomm after they dry and I do the drilling - but so far the pouring in the syringes seems to work very well and you can see into the tube unlike PVC - you can even reuse the cut tubes if you wish - just coat with wax and stop up one end and you can use them over and over - see last photo

    Tried to drill out the tubes shown above and two broke during the drilling - possibly to thin or I needed to let them dry longer - have a couple left and will wait a couple more days and then try drilling those - the 3/4 pvc works well and no problems on drilling they are thicker to of course - ill post more as i see if the other tubes will work

    dan, would it be possible to have a tube in the center to make the drilling easier? another words cast it with a removable center piece or one that is easy to drill? think of it like a core in a mold to allow a recess after the mold is poured.

    I found out this evening if I leave the syringe on and drill first it adds a bit of additional support and the drillling goes easier without the breaking

    Larry =====Below you will see another round of pouring for the fun of it where i put the tube in first (plugging the one end with wax), painting the tube - putting in the syringe and pouring around it with the tube in place - I could have done something better to center them other than some broken sticks but its all I had and was rushing - ohhhh well we will see tomm evening when i take them out...........................thanks for following

    If you are handly at flatwork Dan, try making your own silicone mold with the tube plugs build in...from what I see on-line, real easy! When drilling, you must go slow!! PR gets brittle with a little to much catalyst. A fun trick is to mark the tube length on the blank and add 1/4". Drill to the tube length and glue in the tube. Once set, cut on your bandsaw to the mark just past the tube length. Works good.
