The #23 Pull Truck Resto Stroker

The Project

Just before I contracted farmers lung in May of 2006, this truck is one of the many projects I had going.  Many aspects were planned, including rear air springs and gear. But life can change your plans. This is the last item of my race equipment, essentially unused until 2011 and since rarely. I mean rarely. The camshaft is a high torque low overlap. Originally a Chevy bastardized fuel injection, i.e. throttle body, it is now carbureated. However, no one knows what that is..... New interior and seats. Trans and engine externally cooled and trans rebuilt. Gages, whats that?, replace the "computer".

Lets take a look

engine:

 Headers were coated...oh well

See my wiring harness. What a damn mess. That wasnt me.

Air no longer works. Beats me why.

THIS IS WHY JET LATHE HALF NUT HOUSINGS FAIL

AFTER MORE THAN 4 YEARS

Well, after more than 4 years after delivery and many aborted start - stops, I have determined why the half nut housings fail on JET lathes. Firstly, there is essentially no Q/C. Secondly the half nut leade screw housings do not fit the apron.

typical replacement, I purchased 4":

The problem is the half nuts have to fit the apron cam:

If they do not only one of the bronze nuts will engage, if none.

The apron cam has to fit the leade screw location. So I manually attempted to measure the offset without a jig and my measurements did not repeat themselves to my satisfaction. Finally I constructed a measurement jig.

so above is the JIG, and below it is installed in the apron. The apron was then installed on lathe.

The slot is cut such that I can determine the actual position of the cam lobes. Once this was mounted on lathe, guage blocks and feeler gages gave a high degree of confidence. The gage dimensions were all "square" within +0.001 and -0.001 offset measurements were  greatly simplified.

these are just a few:

from this you can see the simplification of the measurements.

this is where I am to date.

have I received support from JET; yes, however worthless.
Would I purchase another lathe from JET. No. This scenario began in 2011.
