favour request??

[andy230]

I like everyone in this club.  You are all great individuals, with big hearts, massive brains, generous to fault, and always willing to go the extra mile.

Some (like Pat) are a bit ugly, but even the ugly guys are nice, even if they do scare the kids...

I am needing a favour.  Is your heart big enough to accomodate??  (I hope so, as it really pains me to say nice things about folk!)

The opportunity exists for someone, probably someone with a lathe, to contribute in no small way, to the ongoing joke which is my supermono racing career.

I'm replacing the decompresser lever on the srx with a blank.  This way, I wont wreck my new valve, by battering it into the piston at full chat.  Like the old one did...

I need a bit of solid 12mm bar, of length 30 cm. (Ideally it would be ally, but thats just daft, especially as I wont even cut the unused lugs off my frame!!)

It has a groove, (of width 4.5mm, depth 1.7mm) machined into it 3.7mm from one end.  This groove engages with the head of a special bolt, and holds the whole decomp. asssembly in place.  I have now removed the decompressor, and rather than glue in a plug, I'd like to keep the oil seals where they are, and just put in a blank.

Can anyone help me out with a bit of scrap they have??  I'm not in a huge hurry, wont be racing till march or so, but it would be *very much* appreciated, and you can claim 1 free ticket to watch me come in at last place, if I do indeed finish.  You can be proud to know that without your time effort and charity, I wouldn't be there humiliating myself!!

In such circumstances you would retain the right of anonymity...

Cheers in advance, it would be very much appreciated.  And if you cant help then dont worry, I'll just have to (god forbid!) pay someone to do it!!  Obviously I'd cover you costs etc, and buy you a beer, and other emoty gestures.

Cheers for now, speak soon, grovel grovel, bootlick bootlick...

Oi ! thats a bit harsh :-(  I know when I was a baby, my Mum would feed me with a catapult, but I've improved with age :-)

[andy230]

Ha!!  Ok, sorry then mate.  You're the prettiest man in all of ThumperLand.  :-)

And I've just noticed a mistake:


I said:

That sould be "length 30 mm".  What kind of rockerbox would that be with a 30cm decompressor lever??!

Just a thought that might make things easier, assuming you can find a suitable diameter piece of stock. The only reason the slot is machined in the decompressor arm is to allow it to turn. If you just want a blank, you could just grind a notch instead of having to do anything with lathe like precision. It just needs to be precise enough to hold it in the vicinity of the oil seal.

[andy230]

Yeah, good point!  Thanks peter.  I hadn't considered that...

Makes it much easier, PLUS I may not have to be nice to my fellow thumpeteers after all!!  ;-)

So to my next question...  Where do I pick up an offcut of 12mm steel/ally bar??  I know a small precision engineer, will drop by on the way home to see if he has any scrap...  The Biomedical Engineering dept in the Hospital are a bunch of sour-faced b'stards, but maybe the Works Dept will be more accomodating...

Anyone got some 12mm diam x 30+mm bar lying around??

[Ian]

If you can't get any for free ,

Try B&Q I bought some 10mm x 1m for around £5.00 about a month ago.

[andy230]

ta!  good to know.

(but "The Blagger" will only part with cash if *absolutely* necessary!!)

If your stuck I'll pop into CG rees in Cardiff and pick some up and post it on.

Always assuming my butt ugly mug doesn't scare the poor sales Lad away!

[Steve Lake]

erm.... daft idea i know.....but why don't you do like wot i did, just saw off the end of the existing lifter assembly

I'm assuming you have discounted this with a view to retaining an intacto assembly to be refitted when said bike is returned to road legal status prior to being sold as 'never raced or rallied, one careful owner, only used on dry sundays to visit church'



i'll get my glasses guide and coat...

[guest27]

I will try to remember to look int he shed - If I have a bit of steel or ally 12mm X 30mm and if I have I will cut a slot in it for you.  How is that?

Hello Chief!

I'd just rather not butcher more than I have to.  Cos if I want to put it back on the road/ punt it/ etc I'd have to shell out for a new part.  Thats why I havent hacked the frame about either (s'not really worth it, it weighs a ton anyway!)

But yes, if I were in the paddock and had to do it, then I would, but when there's a slightly more agreeable solution, I'll go with it while I can.

(tho I dont suppose it'll matter a rat's ass when I pop the rod thru the cases and bend the frame slipping on all the expensive Rock Oil....!!)

And I saw your post on the supermono forum.  GO ON!!!  Aren't you tempted?  I could really do with the help, they could do with numbers on the grid, and your wife would be over the moon at you taking up racing again! 

Cheers for now,

How is that??  Bloody brilliant mate!  Would be much appreciated if you've got any.  I have a grinder, so could put the slot in myself but if you could, that would be top (3-4 mm from one end).

Cheers for now, let me know if you have any scrap that wouold do the trick??

~Nearly done - just need to trim it back to length - would have finished but lil boy needed picking up from school - you would have thought that they could have stayed there all night?
Small apology - could not find any ally stubs that were not earmarked for the TZR so I uses a bit of 12mm steel.  If you find a 12mm stub of ally send it down and I will do a second - but I am guessing that whilst magnesium would have been nice and ally OK steel will pass muster.  Just need an address to send it to - do not think getting it scanned and putting it on here will work.

Now prepare yourself for a good chortle...

Steel - what a wonderfully broad church that is.  12mm stub in tin of odds looked fine. 50mm long and a little rough on the ends.  Yours truly starts facing it off and curses blunt tool - but does not bother to stop and sharpen it.  Grind up a 4.5mm plunge too for slot, bemoan loss of lil RC 6inch rule as I have not got tool centered properly and it is taking a good shove to get it cutting, curse lath for being as loose as wiofe's knicker elastic as tool keeps slipping - still not too bad job done now need to cut to length - not having a parting tool this is a hacksaw in the vice and then turn to length.  Curse blunt hacksaw blade and lack of new one, get angle grinder out and loads of sparks later ready for trimming to length.  Bit od blueing on end of stub - first mmmmmmmmmm.  In lathe and run facing tool across face - bugger is real blunt just bouncing off face. - bouncing off blue face... mmmmmmmmmmm - tries new file against stub, skids and slides, no bite.  Ah hah not blunt tooling just not mild steel.  So a annealing later it seems to be cutting better.  Not sure what it is, may be a silver steel stub, not going to make a difference to its function but sorry I have decided NOT to bore it through part way to lighten it.  Oh well at least I did not set the shed alight with the grinder sparks...

AND - AND it got me out of planting garlic
