About time Ade :poke: :poke: :poke: :poke: :D

Good to see you back on the job :thumbup:

Great to have you back at it, Ade. I watch a number of projects here that are my favorites.
This is one of my "favorites of the favorites".
Keep at it! This is such a good one!

Hi Ade :wave:

Bout time too (he said hiding, as he hasn't finished bu6637 all for an age!)

I drove past your place working on Friday, figured I'd have to give you a nudge :poke: just to see if you were still with us ::) :)

Looking good.... All except the clamp :(

Glad you've got it back in order.... Thought you might have rushed through it to get out for a race season.... Next year now then?

Looking forward to seeing how the rest takes shape :thumbup:

Ralph.

AdeV:
Thanks chaps... I'll try not to let it go on too long, I have my own engine now, so the 2nd sump will have to be made pretty soon after this one...

Ralph - I don't know whether the car will be out again this season. Dad would say "yes, of course it will".... but we shall see. It had better be off the bloody ramps before the end of the year, I want to get my car moving now! Feel free to drop in any time (except Wednesday morning as I won't be here...)

I'm not too worried about the clamp. I made up for it somewhat with today's progress, tempered by the untimely death of the shop vacuum cleaner, which expired in a fusillade of crackles & a huuge cloud of smoke.

Anyway, on with the show. First job was to do some head-scratching, trying to work out the angle I needed to cut the drain slots at. Eventually, I gave up trying to figure it on a sketch, & drew myself a 2x scale version - which had the advantage that I could check the angle by both measurement & calculation:

19.9o was a surprise, I was expecting a much steeper angle than that. Looks like I wasted £10 buying a 6" long 18mm end mill... I can easily make that cut with my regular 12mm ripper. So, lob it all on the mill, looks like it landed in about the right place:

Note the clamps are further back this time :hammer:

A bit of :dremel: later, and the 1st two channels are done:

The left-most pair of drain holes will be channeled into the wide right-hand slot; the second leftmost drain hole will go into the single width left-hand slot. I've not decided yet whether they'll slope in or just be flat... the slope would be preferable, but will be an absolute bitch to do, it'll either mean mounting the rotary table on the angle plate (THAT would be an interesting challenge), or manually setting the sump at an angle on the angle plate & clamping it down. I'll have a think about that one. There are times I wish I'd bought a CNC mill....

Anyway, a bit more trig got the second angle, and I did the remaining drains that empty on this side of the sump:

The four drains towards the bottom edge of that picture need their slots cutting in from the other side, hence the work is off the mill again. It's late, again, so that'll be tomorrow's job.
