1st dust collection system

[hayu]

I HAVE PUT TOGETHER A DUST COLLECTOR SYSTEM. THE HOSE IS 4" AROUND BUT SO ARE THE CONNECTERS. I HAVE TRIED TO GET THE HOSES TOGETHER AND CAN'T GET THEM TOGETHER. HELP

Butt them together then several layers of Gorilla tape over some popsicle stick splints.   
that's what I would do

The hoses should fit on standard connectors but  depending on the material of the connector you are using you may be able to cut a slit in the connector pipe allowing it to taper in some and the hose should fit.

I have found a couple of ways to join dust collection hose to machines, especially if you make your own connection to the machine. This http://www.canadiantire.ca/en/pdp/dryer-vent-draft-blocker-0642904p.html is just the right size. (Remove the flapper first.  ) The hose slips over it nicely and it also fits into standard ventilation pipes.  Another possibility is a 40 ounce juice can, the one with the two sets of ribs.  Unfortunately they are slightly larger than the vent blocker so it is a bit harder to slip the dust hose over it.

Some other possibilities

As an aside, these http://www.busybeetools.com/products/hose-clamp-with-key-4in.html are easier to use than the one that need a screw driver or wrench.

Hope this give you some ideas.
