Glad to have made it there and back Darren.... :thumbup:

A fun day all round, sorted out some electric string and wiggly amps stuff (TM Boggie) and it's all going to plan to get my mill under power...... Just remains for me to get the mechanics done! :) Yep I know... :offtopic:

Now, back to the engine....
The new design boring tool certainly does leave a perfect hole behind, more than adiquate for the job :dremel: :clap:
And the step drills as said will probably be too long for the job.... But you'll definitly find a use for them :headbang:

The other parts I have seen first hand for this little marvel are very nicely finished. It'll be fun to see the rest take shape :)

I tried to write this last night, but Hypnos got the better of me and that was that! So I finished writing it this morning!

Thank you for your hospitality and help Darren. It'll all help me achieve my dreams of power! :borg: :lol:

Visiting is fun :D

Ralph.

Darren:
It was good to have you round Ralph,

You're nowt like wot Bogs said :lol: :lol: :lol:

If I can help any more just ask.... :thumbup:

Back on this engine build, not a lot of progress I'm afraid, apart from working on my garage, started slating the roof :ddb:, which is very tiring I have to say.

But these plates are taking a lot of effort for what they are, for me anyway... :smart:

For the top plate 18mm holes I did it like this, after some practicing on some scrap first of course... :dremel:

All holes where center drilled and 2mm or 3mm bored with an ordinary drill bit, then I used a stepped drill to the depth my vice would allow.

This took enough out of the center to use an off centered two flute milling slot cutter. You cant just plunge in with the cutter offset as it objects quite aggressively.
The offset was pre-calculated on a piece of scrap beforehand.

In case you missed it this was the holder used, similar to a boring head which I assume would also work just as well.

And the result, a pair of nice neat and perfectly sized holes :)

I'll bet!! ::)

Anyhow... Glad to see this all worked :thumbup:

Looks like we'll be seeing a lively little engine in no time?

Tiling ehh..... Now that's fun :hammer:

:)

Ralph.

Way to go Darren :clap:

Like the use of a milling cutter as a boring bar, very inovative :headbang:

I take it the second undrilled plate is for the base will you spot off the drilled plate for this so they are a matching pair.

Cheers
