    Homemade Induction Annealer

    Can you provide a wiring diagram showing the major components (and their specs...voltage, amperage, wattage, etc.) and how you have them connected and to what voltages. I see the SSR in behind your ZVS board, what look like 2 buck converters on the left, the ammeter and what I assume is the...

    Homemade Induction Annealer

    First impressions...nice build Questions: - what are the specs on your ZVS board? - what diameter of copper tubing are you using? - what amperage does your meter show while the annealing cycle is running? Thoughts: - MORE POWER!!! - Tim "The Tool Man" Taylor (try to get at least 90% out...

    Homemade Induction Annealer

    First I watched this Youtube video My takeaway was that the 3+2 two-layer coil gave the desired power and focus to just heat the upper case, shoulder and neck areas that I wanted to anneal (actually, it is more like 3.5 and 2.5 turns). My coil is about 1" inside diameter (I filled the copper...

    Homemade Induction Annealer

    I am in the process of rebuilding my annealer into a full size tower computer case. I chose the full tower option so that I could use the 3+ CD drive bay space for an integral case feeder (as opposed to mounting it to the top/outside of the computer case). Also, a complete redesign of my case...

    Homemade Induction Annealer

    What is the resolution on your timer? I can only zoom in so far and can't tell if there is a decimal point showing. You should have at least 1/10 of a second control of the time...

    Homemade Induction Annealer

    Do you have any issues with having that big chunk of metal (case holder assembly) right next to your induction coil? For instance, does it get hot too, and does it interfere with the induction field?

    You should always zero at 100 yards (imo). If your hunting and want your scope 'zeroed' at say 200 yards, then just dial the scope to the 200 yard setting and leave it there while you hunt. As far as 0 MOA vs. 10 MOA, go to the following link, select your bullet from the drop down list at the...

    Ruger Precision Rifle Discussion

    I agree with both of the above. Either the 0 MOA or the 10 MOA would be more than adequate, but I would probably go with the 0 MOA in your situation (300 or less, occasionally out to 1000). The existing 20 MOA rail will give you about 70 MOA of 'up' on that scope (looks like about 100 MOA of...

    Ruger Precision Rifle Discussion

    The trade off only comes when your total mounting MOA additive approaches or exceeds 1/2 of the total elevation range in your scope. As an example, if your scope has 80 MOA of total internal elevation adjustment range, and you assume that a typical 100 yard zero would be in the middle of that...

    Homemade Induction Annealer

    If you have the same version of timer (four timers and two relays), then the A relay will close/open during timer 1, then during timer 2 nothing happens (except the timer counts off), then during timer 3 the C relay will close/open, and lastly, during timer 4 it just counts off. For example...

    Homemade Induction Annealer

    There is usually a sticker on the side of the timer with a wiring diagram...I found it to be useful. If your unit does not have a sticker, check the page where you ordered it for a pic with it. Here's the one I got with a pic of the diagram...

    Homemade Induction Annealer

    The coils should NOT touch...that creates a short in the coil circuit that can destroy your power supply. They don't need to be separated by much, but they need to not touch each other. Also, if a case is inside and against the coil , it short circuits the coils, that is bad also...

    Homemade Induction Annealer

    I went against the conventional wisdom around this and the Accurate Shooter annealer forums by using 1/4" tubing and a dual layer coil (3 inner turns surrounded by 2 outer turns... https://drive.google.com/open?id=1oLxBFMN-Ii4Zl__fuFg2fdR_0i7yeShW ) Other than shorting it out that one time its...

    Homemade Induction Annealer

    I fried my first power supply because a case got cocked at an angle when it dropped in and shorted out the coil. I use a pyrex welding shield to prevent that now.

    Homemade Induction Annealer

    Did you make that case drum large enough for larger cases and is the gray part replaceable for different sized cases? The version I made is not nearly as slick as your design, but it will fit belted magnums and 308 sized cases as designed with a little insert for the bottom of the case slot to...

    If you are limited to 36v and 1000w, get a power supply that maxes out all of the metrics that you can - ie 36V 20A which would be in the 720 watt range. (double check the specs on the ZVS board, I would think that they would all be in the normal relation to each other - 36V x 20A = 720W...)

    Homemade Induction Annealer

    Its hard to tell from the pics you show, but something else that jumped out at me as a possibility is the timer unit you are using...it looks like it is switching the full output of the power supply into the ZVS board. I don't know what the specs are on the timer, but it may be limiting the...

    Homemade Induction Annealer

    I would be careful with that single pole relay...as I recall from the accurate shooter forum on this subject, a double pole relay would be better because it disconnects both positive and negative inputs to the ZVS and possible feed back when that much juice is cut off from the board (ie feed...
