Default One Cylinder Boring

This is a stand I made for boring 1 cylinder engines. I needed to bore a e-z go golf cart engine and put a sleeve in it. I diden't have the fancy boring mill to bore it with so I made this stand for use with my 905 Perfecto Van Norman boring bar. The Van Norman boring bar indexes off the head surface of 6 Cylinder and V-8 engines. I machined both sides of the 1 1/2" plate steel and milled a step around the inside to accept a plate insert to hold the jug/engine cylinder. It makes it like the head surfaces on the 6 and 8 cylinder engines. It has a bolt pattern on it to index off the head part of the jug/engine cylinder. I used it to bore and sleeve on the e-z go rngine it worked real easy. Now I'm going to try to bore a 4 cylinder wisconsin VF-4 they have 2, 2 cylinder jugs, I'm going to have to make a special insert for them. Kevin

I think that's pretty slick. I was trying to figure out which old saying was applicable, 'utilization of available resources' or 'necessity is the mother of invention'...anyway I'd like to see a picture of your set-up on a Wisconsin block when you have it ready. Wish I had one of those boring units myself. Phil

The Wisconsin V-4 is a wonderful engine and is long lived and dependable. Having said that it is not very forgiving on the overhaul and you have to hold tight tollerences on everything. Also it is prone to oil leaks so the gaskets have to be perfect. But then, I am sure you knew all that. Good luck.

In the early 60s, I worked at a parts house/machine shop, and the machinist had a similar plate bolted to a steel work table that he used on the one and two cylinder engines. He supported the cylinder with long threaded rods, and a companion plate on the bottom. I also saw him use a dry cylinder hone, when he was taking a small overbore on the cylinder.
