Ahhhhhhhhhhhhh  ............... technology I can understand, though to be fair the slightly older Kent ohv engines were more my era favourites :bugeye:

Ralph,

I was so impressed with that valve tool you made that I showed the missus tonight and explained the y's and hows......pointless of course.... :lol:

A dead impressed Darren..... :clap:

Divided he ad:
Ok, so I left this post for a while.....

I've been very busy.... Doing all manner of summery type things (yer summery is a word. it don't not look right but it's in dictionaries etc  :ddb: )

The job was a success.... It has cured the most violent bursts of smoke and only a bit is left.... Probably residue in the exhaust?

Still.... it did the prescribed job and that's a result  :)


Oh, and thanks for the thumb well wishes.... it's now healed up but still a little tender  :thumbup: The nail is a pain, snagging everything, I'll just have to wait for it to grow out!


Now, a little extra for Darren....

I'll not be using it for a while, well I don't have plans to so here's a pic of it when used on the frame and the base of the Baldy engine I made.

The standard radius. (it's a 1/4" radius cutter.... They're silly money.... but e-blag helped with the slightly cheeper 1/8th one I got :) )


Or lower it a fraction more and move it into the work the same amount and you get an attractive step look (Thanks Bogs :thumbup: )





Hope that helps?







Ralph.

Way :offtopic:  but just a reply to Ralphs little display above.

This sort of tooling can be very expensive, so I have played about with the el cheapo sets of tungsten wood router bits to very good effect. DON'T try them on tuff stuff, but for ali and brass, they give very good results after playing a little with speeds and feeds.
Actually they came up again the other evening when Stew and myself were gasbagging in my shop. I showed him how I was considering how to hold them in a boring bar setup, and use them for turning nice profiles on the lathe.

Loadsa tungsten profilers, for lotsa little cash.

Darren:
Yes I think I did a post on these somewhere once, I bought a handful for about 20p each.

I did use one to make a very small boring bar for my SS crank which worked well. But I wouldn't get any more adventurous on harder materials as John suggests.

But for alloy I had quite acceptable results..... :thumbup:
