so this is not a one size fits all V-block style clamp that puts four highly concentrated points of force on the torch. These are round clamps within .000" to .015" of the torch OD so they greatly reduce the deformation when clamping so that you don’t damage our torch. This allows you to clamp low and allow the Lasers to not cast a shadow.
No need to crush the torch. I tell people to gently tighten the lower clamp first just until the torch doesn’t freely rotate. Then clamp the top clamp.
Overall the round clamps allow for much greater grip with less force than a V-clamp. I’ve been running the prototype for close to 3 years with my IPT-80m. 
Still works great.
Here is the stress loads of the factory clamp from Langmuir. Notice the green parts. This is what causes the deformation that damages your torch. V-Block clamps try to turn round things into square things. lol This is why I use a round clamp to clamp a round object.
