Next up is back to the cast iron and the frame support foot.  At first I struggled to work out how to hold it to machine the base as it was too tall to fit in the vise - ended up drilling a hole through the centre and then counter-boring for a SHCS to enable me to bolt down the casting onto some parallels and machine the underside.  Once that was done it was plain sailing.

More cast iron machining this weekend - the main bearing pedestal is quite a lump so drilled some holes in the underside to take some mass out.  Then cleaned up the bottom face, inverted and then a lot of backwards and forwards to cut the inside away for the bearing assembly.

Simon, I have got to ask why you needed to reduce the mass, or is it a F1 thing?

Coming along well though.

Well it could be an F1 thing but I like this quote from Henry Maudsley;

"Keep a sharp lookout upon your materials; get rid of every pound of material you can do without; put to yourself the question what business has it to be there?, avoid complexities, and make everything as simple as possible."

I've also got in the back of my mind that hopefully one day I'll be lugging it up and down the stairs at Forncett so every little bit saved will save my back.  Lastly won't the original have likely been cored out? :-)

I was going to ask the same question but I guess you are right when saying that the original would have been cored out also.

You obviously did not read to the end Simon  :LittleDevil:

"avoid complexities and make everything as simple as possible."

Looking forward to you making those titanium 10BA fixings ;)

Section 15.1.1 of the F1 regs on permitted materials;

6) Titanium alloys (but not for use in fasteners with <15mm diameter male thread).

You're going to need a lot more holes out of that to get that up the stairs Simon  :Lol:  By the time you get my age they just might have installed that lift they talk about but that's only after they install the hard pipe airline of course   :ROFL:

Glad to see you managing to find some time on it

Thanks Willy!  More work on the main bearing pedestal - cleaned up the end faces and the frame mating face.  Pinched Tug's idea of a lump of Blu-tac to stop the sides 'ringing'.

Road to work was blocked by drifting snow so got some time in the workshop to work on the main bearing cap, first sawed some of the waste away which was a good way of keeping warm whilst the heaters took the chill off.  Then machined the side faces to size and drilled holes for the holding down bolts, bearing wedge studs and two oilers,

Casting was then flipped over to machine the pedestal mating faces.  Some of the stud holes are perilously close to the edges so was worried they might break through either through drill wander or from not getting the casting centred again after flipping but all good so far  ;D

More work done, cut a central slot and then a little bit of clean-up on the top face before job done.

Thanks Tug, progress has been really slow for the last two weeks working on the bearing wedges and inserts.  Started by milling and sawing them out of bar using the dividing head and then carefully milling them to final length.  Used the bearing pedestal and cap as a drilling jig for the wedges and then tapped the holes 8BA.  The top and bottom inserts were then bonded in and left over night to go off.
