1) Cam Test Stand Briggs Adapter  

Because there is a wide variety of cam designs, mounting the magnetic rotary encoder on the end of the cam can presents some problems.  We've developed a new adapter for our rotary encoder when measuring the small Briggs & Stratton flathead cams.

Part Number: CTS-REBF  Magnetic rotary encoder mounting adapter for Briggs & Stratton flatheads, with .75" diameter journals.  The Briggs cam in the picture is being measure with the CTS-REBF and our Universal Flat follower (CTS-UFN).  The standard V Blocks typically provide enough clearance for the gear on the cam.  To accurately measure the intake lobe with the "EZ Pull" compression relief on the intake closing ramp, you need to set the Option of "Cam Lobe may have 2 bumps".  This option is only in the Plus or Cam Grinder version of the software.

For most pushrod cams, the standard adapter which comes with the system works fine.  But for small cams, motorcycle cams, OHC cams we have several other adapters, like at the links below:

for Part Number: CTS-RHD8  Rotary Encoder mount we developed for the Harley Davidson Milwaukee 8 cams.  It is steel and has somewhat higher precision than the "Flat Mount" below, and can be more universal.  It has a steel tapered pin of .250" (6.4 mm) diameter, and a magnet .375" (9.5mm) ID and .750" (19mm) OD .  So if your cam has a small hole in the end of less than .250" and an ID of less than .650" (16.5mm) and an OD of more than .400" (10mm), this will work well for you.

for  Part Number: CTS-RMF and CTS-RMFI  Cam Test Stand Rotary Encoder Flat Mount and Insert will attach the rotary encoder to cams without a flat face on one of the ends.  These are typically motorcycle cams.  

 

  

for Part Number: CTS-LSRI and CTSLSRIC  Larger diameter rotary encoder index (1.00") and magnet/bore to accommodate cams with larger than .625" holes in their ends.  The Compact Design allows for more clearance around index, so it fits on the Cam Test Stand better for more cam designs.

2)  Our Ace Machinist - Mark Sanborn  Mark Sanborn (Tri-Mark Performance, Reedsberg, WI) has been our machinist for about 30 years.  Mark is not only a great machinist and designer, but a great authority on engine building and circle track racing, as well as a great friend.  I call him the "answer man", because of his great knowledge on a wide variety of subjects.  We've asked for his input on most all of our products.  That's him standing behind me in the picture below, PRI show 2010.

About 4 months ago Mark was diagnosed with Hodgekins Lymphoma.  The prognosis is very good, but for about 9 months, Mark will not have the energy he needs to work.  Being a small business man, "no work, no paycheck".

Shane Reinbold, a friend of Mark, started a givesendgo page to help Mark and Tricia cover their expenses.  If you feel you can contribute something to help out Mark, it is much appreciated.  Here's Shane's note:

Hello!  I am writing to you today to both deliver some news, but also to ask for your support. If you haven't already heard, Back in July, Mark was diagnosed with cancer. He's undergoing aggressive treatments and fighting like an absolute champ. However, the troubling side effects and consistent hospital visits have prevented him from working. As you can imagine, this is putting quite the financial strain on Mark and Tricia. And they need our help. I think we all know how generous and caring both Mark and Tricia are, and how they wouldn't hesitate to help anyone in need. It's our turn to help them! I am sending you the link below and ask that you consider how you can help them!
