Maybe they have some special tape, but most adhesives do a poor job on HDPE, its what's called a low surface energy plastic and is hard to bond to.

CNC mill:

The mill took a small step forwards with some parts for a power draw bar (PDB). I bought an almost new 'air over oil' cylinder off Glen that turns 90 PSI air into 3,500 Kg (7,716 Lbs) of ...

I added some storage for the lathe, it gets tons of stuff off the bench and keeps it handy:

The motor shaft is working out really well so far; all the turning is done and now its off to the mill for a key way and a bolt circle. I don't have the right cutter for the key yet, so that's a job f ...

Thanks for the info, how are your motors working out for heavyweight drive? I need quite a long shaft with a keyway and I definitely need to save weight so the Ti shaft is a must. The magnets and the ...

A huge 50 x 500mm round of titanium arrived last week and now its being turned into new shafts for the weapon motor and bearing block. Parting off the Ti was a nightmare; it had extreme ...

The pulley angle depends on the diameter. As a belt wraps around a smaller pulley, its inner edge gets more and more compressed and deforms outwards, while the outer edge with the reinforcing cords st ...

Absolutely! The pulley depends on the wedge action of the sloped pulley sides for grip.
