I'll put this up as well just to keep it complete - I can remember setting the casting up on the central boss, didn't know any better at the time but I won't be making that mistake again...smile

The 'little shoulder' on the side is only partially painted which makes it look a bit worse than it is..

Cheers

Next is the Eccentric Sheave (Cast Iron).

The Eccentric Drawing..

459. the eccentric drawing..jpg

I did try to sort out my Flywheel, not very successfully really but I'll leave it as it is now I think - shame I was just lacking that bit of basic know how when I did it...

I thought a quick coat of paint (primer) would hide some of my sins - you can see I've been all around the rim on the Mill.. I've not touched the bits I skimmed between centres on the Crankshaft as they seem fine..

I have a video of it spinning on the Lathe but its none too pretty, if anyone wants to see it I don't mind posting it here..

Getting a bit ahead of myself here, but these were cheap (£6 I think) - hole punches ready for some gasket making in due course..

Main thing for me is that I feel I'm definitely learning and going forward...smile

Hi Jeff, that roller photo is impressive.! I wouldn't know where to start with that..

The form tools and holders are very useful to see thanks - and you've set me thinking that I can make one like that in the first two photo's to do the internal groove in the eccentric strap idea smile

Cheers

I was lucky to salvage this as I had a bit of a disaster - I thought because it was such a small part it would be easier to not part off in the Lathe and Mill it out on the Rotary Table from the long bar as it is and being easier to get a good hold. That was a lesson leaned and I won't be trying that again, maybe it would have been ok with better equipment but not with mine and my current cutters, made a terrible mess and then the part moved while milling. So I did by hand and eye (no filing button). Hoping it will be ok though, maybe shorten the short thread a bit on the Valve Rod when it comes to a final assembly and I can see how it fits.. Its a bit thinner than it should be around the radius.

I was going to carry on with the eccentrics now but I've been thinking about trying to improve the inside rim on the Flywheel first - I did the wheel before learning of the 'pencil' method of setting up from Jason and it wasn't set right in the Lathe chuck. Setting up castings have been almost 'easy' with the ones I've had ever since using his method. As I think of this as another 'learning' engine I was going to leave it as it is, expecting there would be lots of mistakes, but the engine is going better than expected so far and it really is the only thing that's not quite right. I wanted to ask if its possible to improve the inside rim on the rotary table on the Mil maybe, or is it too late now, I don't think I would fork out for another casting as its not that bad, I'll just leave it if its a no no..? The outside rim is perfect - to my eye anyway, I just didn't know how to set it right from the beginning back then.. I was just lucky when I did Victoria's.

The finished Valve Rod and Head. (the camera is making it look worse than it is, all looks shiny to the eye...)

If anyone can advise if its worth trying to sort out (flywheel) I would be grateful - I'm not worried though if it stays as it is.. Next engine i'm determined to stay with each part until its right smile

Cheers

Thanks Julian that's very kind of you, I may well take you up on that in the future..!

and if you are ever down this way and fancy calling in it would be great to see you, kettles' always on - I'll pm you our tel no later so you have it just in case.. smile

(same goes for anyone else on here if you find yourself in Abergavenny) smile

There is something I've been thinking about asking about wheel castings, silly question I expect - i'll add to my post later...

I've just added a set of radius gauges to my list for next time I'm ordering..!

RDG seem to do them and very cheap.. smile

edit: thanks, it took me a while to see where the 0.094" comes from but I see now, thats a really useful thing to understand...smile I'll know next time..!

Thanks Jason, I'll have to get another button tool as they are so useful, I lost track of mine when I moved indoors I think, can't find it anywhere, I see now how it could be used for this sort of thing.. idea smile

Hi Jeff

Thanks, very interesting, that's a technique I knew nothing about - if you do come across a photo of the tool and holder that you made it would be great to see..

Cheers

A few more photos of progress with the Valve Rod Head..

Milling out of the 7" bar supplied..

456 the valve rod head 6.jpg

and then onto the lathe for drilling and Tapping - I made a silly mistake in drilling the cross hole in too far from the end, so a bit more facing off afterwards was needed than could have been..

456 the valve rod head 7.jpg

Tapping the 2BA hole for the Valve Rod..

456 the valve rod head 8.jpg

and test fitting the Valve Rod..

456 the valve rod head 9.jpg

I didn't understand the 1/8" radius reference on the drawing for the ends, or rather how to do that accurately on the lathe - so I did at 20 degrees with the top slide - but looks ok I think.

456 the valve rod head 10.jpg

Next to part off and radius the end on the Mill and Rotary Table..

Did anyone see the Rossi - Marquez saga from Sepang on Sunday !!. I reckon Marquez was asking for it.....

Agreed Roger, Marquez was given exactly what he was asking for - brilliant defensive riding by Rossi (as usual)..

Made a bit of a start on the Valve Rod Head - its only a very small piece but needs to come out of the 7" x 1/2" x 5/8" bar supplied for the Eccentric Rod...

456 the valve rod head 1.jpg

I'm finding using edge finders when possible are more accurate than marking out..

456 the valve rod head 2.jpg

Back to drilling Mild Steel again, doesn't seem a problem anymore...456 the valve rod head 3.jpg

The cigarette papers are great Bert, thanks again - its easy to move the tool with it spinning to just drag the paper away, no mark left on the work - and the tool is one thou away, same result each time...

456 the valve rod head 4.jpg

I'm going to try and make on the full length bar so its easier to go on the lathe (for drilling and tapping) - after milling to size, then cut away and radius with the rotary table at the end - the chamfered end left 10 thou over length to face (and clean up) later at the same time..

Jus one side milled down..

Just the Valve Rod done today..

Definitely a lot easier to do in two passes with the Die - I'm not sure its quite straight but very close, I'm guessing it would have been more accurate with a Tailstock Die Holder unless its just that I've not cut the 3'4" length threads quite as deep as the other maybe - it would have been easy to have tightened the die the same for both if I had thought, worth remembering next time to do that..

Thanks Jason that will make things easier and a good way to go about it, I've struggled a bit cutting threads in Stainless Steel and so was especially wary of the oversize Rod - and I'll keep a look out and get a Tailstock Die holder before too long..

Also thanks very much everyone for the other comments - I've just read that not all has been as it seems on here lately which helps..

Cheers

(Just getting ready for carrying on tomorrow..)

Making another 'split sleeve' this time for holding the Stainless Steel Valve Rod.

455 the valve rod 3.jpg

My collection of these is ever growing..

For anyone interested I think the numbers were..

Valve Rod diameter - 4.75mm

Sleeve drilled - 5mm

Slitting Saw thickness - 1.62mm

(so enough slit room to close tight on the Rod when clamped - and easy to get the sleeve on and off)

455 the valve rod 1.jpg

Not a very good photo but the sleeve should be able to hold tight enough without marking the Valve Rod - May reduce the diameter a couple of thou with a file in the lathe to make the threading easier - the rod is slightly oversize for the 2BA thread at the moment.. Unfortunately something I don't yet have is a Tailstock Die holder..

(I'll clean it out before using).

455 the valve rod 4.jpg

Something of nothing I guess but all part of getting the engine built..

Cheers

Garry

ps. for anyone that is still interested in following, if I disappear off here in the coming weeks I may jump over to MEM to finish the build - all the H&S talk on here now is a big turn off for me..

25/10/2015 12:00:14

Thanks Jeff, it's been a while since I've had it in one piece and was good to see the progress..

Next is the Valve Rod and Valve Rod Head - followed by the Eccentrics. First though is to make another split sleeve to hold the Rod in the Lathe..

Cheers Jason thumbs up - and i've managed to get some locknuts ( thanks again Bert ) along with various others for some stock, including some in brass which I may use come the final assembly, oh and some copper washers as well.. smile

Couple of photos of progress so far, nothing tightened and the Top Cylinder Cover isn't on - still lots to do..

I don't think the Flanges look too bad.
