Milling profiles (Help!)

[methuselah1]

Folks, I'm usually a Westbury builder, but I've recently started a Whittle V8. The timing gear cover has a basic profile with many lugs around the periphery which the studs pass through... How on earth do you machine these things manually?!

I don't know how to upload photos, but here's a link to a webpage with some photos of what I wish to achieve, to the bottom -

When Ned Westbury made the Wooden moulds, he obviously, made a base and added added set of mugs held by glue.
So you make the base out of steel instead and 'glue' the lugs with a welding set.

If you followed what I was prattling on about a fabricated Universal Pillar tool and a Stent tool and cuttr grinder on another reply today, that is what happened.

I'm a long retired 'bean counter' not anything else and bought sa clapped out baby Mig for £15 and the rest is history. ame old job, same old ****?

My project is a bit small for that, but thank you for replying! I've added a link, so people can see the project, and the timing case I want to make.

Found this pic. Is this the part? If so the main arc (red) looks like it would be made milled on a rotary table. The lug (like where the bolt is) might be made with a filing button as a guide. I just joined up on that io group forum for a looksee. I'm sure there would be some additional help from folks who made the exact part you are wondering about. Let us know if you learn of anything new

Thank you, and I will share anything I learn...

Hi,

As Petertha said - while it would be possible to do all the machining using a rotary table, the numerous set-ups would be tedious and time consuming. It would probably be quicker to file the profiles

Your link doesn't work.......

The plans show the two radius's and the distance betwen centers.
Do you have a rotary table?
Do the center holes then clear out the center and work from there.
One step at a time, it will come to you. Do the outside perimeter with the bolt bosses last. File the outside profile.
