Nice score Peter, I think you are the same as me, bamboozled by electwonicals :(

Graham mower engines are only low compression and run better with 91 octane, the higher octane fuels also seem to go off quicker.

Ken, you say it is a Rover and you say it is a 2 stroke, I'm thinking that it likely has a Suzuki engine ?
If so, put the throttle into the choke position, then pull the air cleaner off and stick...

Yes Stuart it is all pretty thin, there is not much to play with and I'm not really happy with the tube.
It's hard not to deform the tube, so I really need 2 plugs, 1 inside the tube at the chuck...

I often went out with the FIL doing fencing, mostly we would just snap them off and belt the pointy bit leftover with the back of the axe.
But if you really need to get them out then a trawalla jack...

G/day Stuart, I wanted to press the boss onto the tube then 4 light weld's internally approx 20mm long 90 deg apart, and then slide and loctite the ring gear on.

If yer got nuffin ter do ya cud fix the leaky float valve in the evap on da shed :D

I ended up skimming .005" off the boss just to get the ring gear to slide onto the boss nicely, now I have the problem that when I

G/day Seymore, I am not keen on tapping into 2 dissimilar metals, and besides that I there isn't much left on the boss that the

Thanks Jekyll, they didn't have it either so they are getting it in.

G/day old biker,
I like it, it looks good and I can appreciate the work you have put into it but I need to ask the question, what does it do ?

Thanks Kryn, Healesville doesn't even have loctite let alone eskimo's :)
thanks m8 but I think I'll go the loctite.

G/day Stuart, there is no mating part, in one of the photo's I put in a another camshaft just to show what the ring gear

Thanks for that data, you gave me a shove in the right...

G/day Gammaboy,
Or even silver solder, or even a stainless rod.
Unfortunately I got sick of paying rental on bottles some time ago for how much I used them.
But good idea, thanks

G/day Ray, the ring gear is to be fitted at the far end of the shaft away from the heat, also I think that mounting work on standoffs will reduce heat transfer.
I thought about the heat shrink fit...

I really hate it when I use a lathe as a welding jig so I thought I would do something about it.

Peter. I have one of those on my mill, if I was to buy again I would get a bigger one.

Hi Simon, you could make a plug with a shoulder and a centre hole to fit in the end of your hollow bronze and then use your tail stock centre into that.

I was having a look at the company that BaronJ got his grinding wheel from and came across this,

"SKYTEC-PCD
Grinding tools for cutting inserts with PCB or PCBN cutting edges or made of ceramics"...

I used a blade similar to this a few years ago, it worked fine
