Inspecting the Ride
Craig Sanderson, Ph.D.,
P.Eng. Was the engineer I chose to inspect my ride.
He is based in Burnaby BC. I chose him for several reasons.
1) He had all the credentials necessary to
do the job 2) he had lots of experience being an engineer for some 40 years and
3) because he inspects the rides at the Pacific National Exhibition (PNE) and therefore specializes in amusement

Craig (the engineer) came over on a nice sunny day, I met
him at the Ferry terminal in Departure Bay as he came over as a foot passenger which was an effort on my
part to keep the costs down, engineers don't come cheap.
I had already set the ride up for him so that there
were no delays, time is money! I was feeling pretty good and was hopeful that there would be some minor issues that
could be dealt with easily, and then I could order my BC Safety Authority inspection and finally get my license and
permit to operate my ride.
By this point I was getting nervous about my time
constraints with the beginning of my season fast approaching and contractual obligations looming. Of course
generating some income with the ride would have been welcome since all I had done for two months was shell out
money on a daily basis.
I could not have been prepared for the blow I was about to
be dealt. Craig began to inform me that the quality of the welds did not even come close to complying with either
Canadian or US standards. I swear I didn't hear half of what he said I was so dazed/shocked.
He spoke of compromised welds, porosity and other technical
terms I've never heard before.
He pointed out the seat belts, some bolts were lose, some
missing completely, these were put on at the factory and so I never gave it a thought to check them. However,
considering my experience to that point I should have known that the quality of the seats would be no different
than the rest of the ride.
Not only that but Craig pointed out that the bolts used
were inadequate since they did not protrude through the nut by at least two full threads, which as I have stated
before is of common knowledge to manufacturers, and if it is not then they shouldn't be building things that can
endanger peoples lives. I do intend to let all safety authorities in each of the US states become aware of what I
have received from Poretskin.

It was the welds that was now the major setback the seats I could handle by simply
replacing the inadequate fasteners, yes it was a cost I didn't need but then Poretskin had agreed to
reimburse me. I found that promise to be as hollow as his description of his ride.
I will highlight the Engineers report on page 7 since there will be much space
needed. In the meantime I will show just a few of the images the engineer took and marked the
Many cross sections of the seat posts were not even fully welded here are a few of
Other welds were incomplete or so poorly done there was rusty water dripping
out of them, which confirmed the weld was compromised. I have spoken
to many professional welders who have suggested that a second year apprentice could do a better job
than this manufacturer Fun Attractions USA Corp. was turning out.
The towing yolk the welders at the manufacturers plant realized that their welds were
so poorly done on the towing yolk that they put reinforcing/strengthening plates (called doubler's) on
the welded joints then proceeded to weld them just as poorly.
I could put over a hundred images of the welds here but it will simply take
up bandwidth and my time.
I was now looking at a major undertaking in both time and labour not to mention
the cost of a professional welder. All the welds had to be ground down before they could be re-welded. To
save costs I had my son and a retired welder friend help me it was arduous back aching work.
