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:

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