Nice setup Dean. Is the fixture sleeve (center bolt) on the crank end elliptical? What holds that end down?
I have a converted Tobin ARp insert resizing machine that i hang the rod by the piston pin hole and center the big end on the outboard end of the boring bar It has a hyd feed and can get almost a insert finish. THe top and bottom bores are within 003 th of parallel.I can adj to any length rod and bore in sets to make sure they are all the same length to smooth out the running of the engine.
Lowell,
Any chance you can post a picture of your converted Tobin ARP setup?
I have got 2 Tobin Arp semi brg. machines converted to bore rods and thyey will bore to almost a insert finish and all the same exact length my son says he can send pictures of the setup and will send in the future You don't have to tare down after to tighten bearings because of the good finish.
Hi all,
Here are a couple pictures of the rod machine I have been fortunate enough to use for 8-10 years.
It is a Peters, made in Paterson, NJ. Sorry for the mess, it has been used quite a bit.
