Hey guys, does anyone have good plans to make a bore adaptor that can have the bore sizes changed? Or a link to just buy one.
Cheers

They are pretty easy to make, and as far as I know most here seem to fabricate their own to suit a specific personal favorite engine.

Wow for those prices I will make my own lol, yeah I will just have to get buddy buddy with the local machinist I think, I have lots of different engine types to work on so I will have to make a number of adaptors, oh well add it to the list hahaha. Thanks guys

I've made several using cast iron cylinder sleeves and cabinet grade plywood.

You need something pretty decent to support the weight of the head, but the actual bore tube itself could be pvc pipe or thin wall stuff.

In Australia, standard PVC sewer pipe is 4 1/16" bore (103.2 mm)

MDF with good thickness, router, PVC pipe, as Tony says glue slot PVC ... Easy.
Tony which the measurement system in Australia? metric or inch

We are completely metric here now, we officially converted from imperial in 1970.
But some things like pipe and pipe threads still use the original exact inch sizes rounded to metric.
For instance, 3/4 inch bore water pipe is really 19mm bore, but we call it "20mm pipe"
Four inch sewer pipe is "100 mm pipe" but it's really a bit bigger than that.
We still use the same old British BSP imperial pipe threads on our new metric water pipe.

Only place in the entire world still officially stuck in imperial is USA.

Only place in the entire world still using Imperial is USA.

Here in Brasil, little things still use imperial.

thanks.

This map is pretty interesting.
