Dvorak Machine - Multiple Carburetor Synchronizer

FOR STREET TIRES OR RACING SLICKS; GAUGE MEASURES TO ACCURACY OF 1/1000 OF AN INCH. ONE BUTTON ON, ONE BUTTON ZERO AND INCH/MM CONVERSION BUTTON. TAKES SECONDS TO OPERATE AND YOU NEEDN’T EVEN GET DIRTY

SORRY, BUT THIS PART MUST BE INCLUDED HERE!
ENSURE CAR IS IN PARK AND SUPPORTED BY STANDS, BLOCKS OR OTHER POSITIVE STOP DEVICE. (CAN YOU BELIEVE WHAT WE ARE HEADING FOR?)

KEEP TRACK OF THE TREAD DEPTH FROM WEEK TO WEEK OF RACING. CHECK IN DIFFERENT PLACES AROUND THE TIRE TO CHECK EVENNESS OF WEAR. CAN GIVE YOU A CLUE AS TO THE FOOTPRINT YOU ARE LEAVING. YOU CAN EVEN FIND OUT IF YOU ARE USING TOO MUCH AIR PRESSURE…OR NOT ENOUGH. CAN EVEN INDICATE BENT HOUSING, AXEL, BAD SPRINGS AND JUST A HOST OF EVIL THINGS THESE CARS GO THROUGH.

WHEN YOU ARE HOOKING GREAT, AND HARD, AND THE ET’S ARE FANTASTIC….THAT IS A GOOD TIME TO CHECK THE PATTERN, TREAD WEAR ETC. AND NOTE THEM IN YOUR BIBLE. (YOU DO KEEP A BIBLE, DON’T YOU?) WHEN THE HOOK BEGINS TO FADE, INDICATE THAT AS WELL. YOU MAY GET A FEW MORE LICKS IF YOU ADJUST THE PRESSURE UP OR DOWN AS THE WEAR INDICATES.

IN ANY CASE, THIS IS A TOOL NO RACER SHOULD BE WITHOUT… OR YOU STREET GUYS. SAME THING APPLIES….SORT OF.

Digital Tread Depth gauge:

NUT AND BOLT THREAD GAUGES

Truly a neat and accurate way to verify the thread sizes of both nuts and bolts, both SAE and metric. This set of 26 gauge plugs have a male end and female end, all sizes clearly etched on the body of the gauge. All gauges are wired together to keep in order of size and group and are easily transported to the work for simple identification.

Sizes run from 6-32 to ½ 13 in both fine and course, and in metric from M-4 - 0.7 to M-10- 1.5.

If you are like me and sometimes the size and/or thread of a bolt doesn’t come automatically, this is the tool for you. I hang mine on the outside of the tool box and I use it more than I’d like to admit. Especially the metric stuff. (Some of you, it would be just the opposite) trial and error is costly and time consuming. Do yourself a great favor and have this set where you can get to it on a moments notice!

Available:

Metric only
SAE Only
SAE METRIC Combo

PORTABLE HARDNESS TESTER

ANOTHER AWESOME TOOL FOR YOUR BOX!

THIS NEW INNOVATIVE FILE SET PROVIDES A QUICK, INEXPENSIVE AND SIMPLE WAY TO CHECK MATERIAL HARDNESS. NO NEED TO BRING THE MATERIAL TO BE TESTED OVER TO A HARDNESS TESTING MACHINE; JUST BRING THIS FILE SET (6 FILES FROM 40 TO 65 HRC) TO THE PIECE TO BE TESTED.

FOLLOW THESE SIMPLE STEPS TO TEST YOUR MATERIAL;

START WITH THE BLACK HANDLE FILE (65 HRC) AND RUN THE FILE OVER THE TEST MATERIAL. IF IT MARKS THE MATERIAL, THE MATERIAL IS LESS THAN 65 HRC!

CAUTION: PICK A NON-CRITICAL PLACE TO TEST. KEEP AWAY FROM MACHINED SURFACES. THERE IS ALWAYS A SURFACE THAT YOU CAN TEST THAT WILL YIELD THE SAME RESULT AS A CRITICAL MACHINED SURFACE.

TRY THE BLUE HANDLE (60 HRC); IF IT DOES NOT MARK THE MATERIAL, THE FILE IS SOFTER THAN THE MATERIAL. IN THIS CASE, THE MATERIAL IS BETWEEN 60 AND 65 HRC.

IF THE BLUE HANDLE (60 HRC) DID MARK THE MATERIAL, SIMPLY TRY THE LIGHT GREEN FILE (50 HRC), AND CONTINUE UNTIL THE MATERIAL IS NOT MARKED. THE APPROXIMATE HARDNESS OF THE MATERIAL IS BETWEEN THE FILE THAT MARKS THE MATERIAL AND THE FILE THAT SLIPS OVER THE MATERIAL.
SEE HOW SIMPLE THAT WAS?

GREAT FOR CRANKSHAFTS, CONNECTING RODS, BOLTS (BE CAREFUL HERE!) RING AND PINIONS* AND SO MANY OTHER THINGS IN OUR PROFESSION OR HOBBY!

*RING AND PINION: THE RING GEAR AND THE PINION GEAR MUST BE VERY DIFFERENT FROM EACH OTHER, OTHERWISE THEY WILL FAIL.
