Of course I like more the bonded tube solution, in fact, none of the blocks i've made have barbs.

But still lots of people likes brass barbs, and it seems to me that improving the reliability in this case is good. Also, the microfractures problem is present in every machining step made on polycarbonate: Sawing, milling, drilling, etc.

I'm sure that none of the block manufacturers that produced the cracking tops that polycarbonate a bad fame tried the "solvent trick" Maybe it don't avoid completely the problem but sure helps a lot.

If someone wants to use solvent in machined surfaces there's another precaution needed: No cutting oil can be used, It's going to penetrate the cracks and ruin any solvent job.
