    Planet Mesquite is now dry - MC is below 7% - ready to start final turning / finishing. First order of the day is to secure loose bark and fill bark inclusions. In past replies to posts I've mentioned injecting low-viscosity epoxy - in brief, the combination below is Aero-Marine 300/21 and a #22 hypodermic which costs $0.25 at CVS.
    If anyone on the forum would like detail I'll be happy to provide.
    John

    Do you warn the wood before injection?
    :). This is going to pinch a bit :)

    Seriously thanks for the update.....

    Have you had any problems with the epoxy curing process? I have heard large amounts of epoxy "crystalize" if you pour too much at one time. Have you had this experience with Aero-Marine?
    I am very impressed with your Oneway setup that you have posted about. How hard was it to line up the tailstock with the spindle?

    "I'm going to give you a shot. Then I'm going to pour one for myself."
    Do you not need a doctor's Rx to buy a needle/syringe? I used to get mine at Tractor Supply. No needles needed but used to measure epoxy.

    No Rx needed. I use syringes (sans needle) to inject small amounts of Inlace into crevices in mesquite.

    Here on the farm we go through a lot of syringes for veterinary use. Order them by the case. But they sure come in handy for all kinds of other tasks.

    It depends on what state you are in . Some states do require RX to help control drug abuse. Some Pharmacists will only sell syringe to people with RX for injectable medications.

    Gerald, I live part-time in the state of confusion. TSC has the needles in a locked cabinet. I would think that there would be certain requirements to purchase the needles.
    FWIW- Controlling drug abuse is like trying to nail a piece of Jello to the wall.

    Nailing jello to the wall can be accomplished just takes some thought. ( one solution don’t take it out of the box)
    The brute force approach usually gets a little bit under the nail head.

    As far as hyperdermics some jurisdictions give them out to prevent spreading diseases.

    I’m often amused at how much money, time, cancelled events, inconvenience ....
    are spent to prevent about 30 lighting deaths a year. of course lightning has no lobbyists.
    The reality ispeople still die from lightening because the only way to stop lightning deaths is prevent lightning.

    To tie this to woodturning don’t cut wood in a thunder storm.

    Happy new year all

    REPLY to epoxy questions:
    I have not had the problems of curing or crystalization - that may be due to the material and the application.
    MATERIAL: Aero Marine, West and System-3 are all the slower setting types - at 70-degrees I can mix a 36-gram batch and take up to 30-minutes to apply. I found that the pressure of a hypodermic can accelerate the thickening so I use only the 3ml syringe instead of the 10ml. The reason I stick with the 300/21 is its lower viscosity.
    APPLICATION: To my thinking there are two primary variables: STRESS/COSMETIC and SIZE OF GAP. One of the most challenging is a crack across the pith. I always start by injecting the 300/21 and then filling with 400/21 or a thickened 400/21. If a high stress and large gap (see pics below of steady rest collar glued on to surface) the only way to go is WEST G/Flex-655, especially if the wood is wet. WEST G/Flex is also cycloaliphatic - I will generally injected the 300/21 and then work-in/glob on the G/Flex. G/Flex is also compatible with System-3 pigment which is also cycloaliphatic.

    REPLY to lathe modification: I used transits (both laser and optical), lots of string overhead with several plumb-bobs - it took some hours.
    The larger question is how it went together: After several, and I mean several, really bad ideas, I called Kevin Clay - he is the president and an engineer at Oneway. Because he has all the drawings and CAD/CAM files, he made the bracket (where the I-beams attached to the lathe) and the two risers that elevate the 17" extension - I think he charged enough to maybe cover the cost of the 1/2-inch steel. Now my arms are a bit longer for hugging myself for making the decision to buy a Oneway - it's made at their shop in CA and cost maybe a bit more, but you get the expertise, creativity and help when you need it.

    John, I have always enjoyed viewing your turnings but really appreciate the time and thought you put into doing it safe.Thanks for sharing.
