I considered that too Andy, but the chances of finding a suitably short
one takes considerable search time, so I went to Lowes and picked up
enough pvc sched40 pipe and have the stuff nearly all printed already to
make 2 of these out of 3 pieces of 2 foot pipe, 2", 3" and 4" in
diameter. 1st one s/b done by 4AM.
That is the beauty of 3d printing, you can make what you can measure. In
this case moving stuff around for clearance to other stuff in the
environment it has to work in.
Further updates. I'll send pix but no matter what size I scrunch them
down to, JK rejects them. Why is that? I'll attach some png's from
OpenSCAD anyway cuz a pix is worth 10,000 words. The 3 combined is only
around 63k.
This fits the old style shop-vac bucket-vac with both ports facing up.
I assemble this using 1 foot of a 2 foot piece of 4" sched40 as the
outer hull. the inner 2 inch and 3 inch pieces will need to be cut to 10
3/8", 1 & 5/8" shorter.
The internal offset is driven by the clearance to the intake port and to
the motor housing on top of my older style bucket-vac. The top end of
the 2" section will have 4, 1 in holes drilled in the side with a hole
saw to function as the 2 inch to the clearance between the 2 inch and 3
inch sections. The end of the 3 inch fits in the notches cut in the
locating dividers which serves as the 3 inch to 4 inch transition.
The rest will be sawed to length on my Bosch cantilevered chop saw. I
can make more of these end pieces if someone else needs them. PM me for
details.
Take care & stay well, all.
Cheers, Gene Heskett.
