I am using a 35:1 gear ratio for my arm lift, will a 21:1 be suffice. It will definitely be faster but will it support my arm. It is a single bar lift.
It should, I use a 1:15
The most common ratios I have seen are 1:5 with 100RPM cartridges and 1:7 with 200 RPM cartridges.
I have been using a 1:7 for my arms which are holding the intakes
Is it a Dr4b type lift, or just a small lifter?
I mean technically both lifts would use 1:7
It is just a single bar
We have a 15:1 ratio for our dr4b
I feel a 1:7 would work fine, but if you want a lot of torque (heavy claw or rollers), I would maybe double or triple that. I have a Dr4b with a 1:36 gear ratio.
