Top tip for cleaning cast angled faces.

[MWParticipant @mw27036]

Hello,

Here's a tip for when you need to clean up a face when milling angled cast iron faces, don't faff about with a tilting head/vice when you don't have to! why not set the face level free hand? for some degree (little joke) of accuracy, use a mini spirit level to do the hard work for you.

Thats the way I do it as I on't have a tilting vice or swivel head mill but use a Wixey angle box for setting the angle

Jason B,

I like your approach as shown in your first photo. If you use this setup often I suggest fastening a piece of round stock to the underside of the plate at thr right end. That way you only need to clamp the round to the table, eliminating the fussy setup on the right.

It is quite a common problem on certain miniature loco designs where the cylinder block needs machining at quite a precise angle for the steam chest. If the angle is not correct it throws out the motion plate dimensions and valve gear accuracy.

I have also machined the cyinder blocks of LBSC's Pansy after silver soldering on an additional block on top to avoid the 'bent' blast pipe arrangement and reposition the steam inlet further forward

In my case it was usually the use of a bit of trigonometry plus double check with careful marking out – probably similar to the method JasonB uses.

Cheers,

Julian
