Building the Buzacott

Useable machining setups for making the Buzacott model.
In general, these examples can apply to any model construction.

The following is intended as a guide to help aspiring modelmakers with a few ideas for setups. I am only offering my methods as one way of achieving a reasonable result. As I have now built 9 of these models, I have found the following setups to be effective in producing a good working model. I must stress that there is no way to take short cuts or be less than spot on with your machining. Errors MUST be rectified as you go along or you can be sure they will show up near the end of the job and DEMAND to be rectified then!

A couple of points that may be of help. Bore and counterbore the block. THEN make the liner o/d to suit. Also, it is easier to fit the piston to the liner than the other way round.Make the o/d of the mains to fit the block. IE, do the block first.
