    RMS delay tool on hobby line cases?

    I was wondering if you can use the delay drilling tool on the delays for the 29/40-120 and the 24/40 reload delays. If this is in the wrong section(I.E. propulsion), please let me know.

    Thanks!

    I use it. Just have to be careful to go in the middle. I start the hole by hand and then put the drill in the tool.

    Yes, they all use the same 18mm diameter delays.
    I aim at the stars. But sometimes I hit London.

    Does the delay not fit the tool correctly?

    I didn't even know they made a 29mm version...I just use a 38 using the 2-step method I mentioned above.

    Maybe you have the older "non-universal" tool? I'm new so I'm just guessing here. Maybe someone else can enlighten us to whats going on??

    Im confused why you need a “two step method” for the 38? There is an 18-38mm rms drill that works for everything 38mm and smaller, because they use the same delay diameter. There is a separate 54mm tool that works on the wider delays in those motors.

    Well it appears I've been flapping my jowels unnecessarily. It's been a while since I've shortened a Hobbyline and my poor memory played tricks then. Confusing CTI tools where I use the 38 on 29s. My bad, sorry.

    Tip: normally you hold delay & turn drill.
    For Hobbyline it's easier to hold drill & turn delay...better control on tiny item [for me anyway]

    Just be mindful / AT has two different delay drills - an RMS one and a universal one.

    I got caught in the field the other day, - was planning on using my RMS tool on a DMS g80 - had the presence of mind to check and luckily my local vendor knew the score and had the universal one in stock.

    an RMS one and a universal one
    Would I be correct in assuming the universal one is usable with all delays? or just those 38mm and below?

    Universal tool is for DMS motors only.

    According to this:

    http://www.aerotech-rocketry.com/upl...%2012-6-16.pdf

    it should work for DMS motors of 29-98mm diameter.
