overall this is quite good quality and amazing value. There is certainly room for some improvement in the device, and most home workshop people will make those mods over time. The mods are; a) bicycle handlebar grip on the actuating lever, b) improve the ram adjustment by either putting brass/nylon tips to the adjustment bolts, or inserting brass packing shims to reduce gaps, and provide a non-galling contact, c) bush out the ratchet pawl so it aligns with the ratchet gear, and centers on the gear. None of the mods described are needed for immediate use, but they do make the tool much nicer to use, and extend the tool life considerably. Ram tooling mount hole is a simple 12mm ID hole with a pinch bolt.
