Good Day All, The international workshop manual suggests that bore and fit oversize pistons.
We always used cylinder boring bar such as Van Norman . These boring bars only rotate a cutter at the bottom of the boring bar, also there is adjustable traveling steadies ( called cats paws ) that stop chatter. We have bored cylinders on a horizontal mill but the boring bar must be supported both ends . similar to boring bars used to repair earth moving pivot bushes. Boring a cylinder is the easy part, getting the correct depth and cross hatch on the cylinder bore is the most important part. regards john ________________________________ From: Kirk Wallace <kwall...@wallacecompany.com> Sent: Wednesday, 2 August 2017 4:08 AM To: emc-users@lists.sourceforge.net Subject: Re: [Emc-users] Cylinder Boring On 08/01/2017 10:56 AM, Ed wrote: > First question is: What machinery do you have to work on this? > > Vertical mill? > Boring head? > What size head? > > Lathe with four jaw? > > Etc.
