When I left school at fifteen my first job as a Turner Improver was at a small shop in London UK machining water pump castings and one job was on the production line chasing brass shafts and I found that slow rpm was not good it went 100% better with a higher speed, that was 70 years ago, don't...

I built Westbury's Sealion and he uses the recessed cup and circlip type and that engine should run rpm up to 10,000 Edmund..........Alberta

I have a Taig Mini Lathe and I scaled down a copy of an old fashioned spring parting off toolholder it really works great, Edmund.........Alberta

G Jones, The Taig lathe is actually very accurate in use and if Jerry Kieffer can produce small Models on Sherline equipment the Taig will also, incase you might be interested take a look at some of my videos on you tube my channel is listed Walter Maisey

G JONES, put your $100 away for 5 months and you have enough to get yourself going with a new Taig lathe and a milling attachment that is what Taig is all about maki9ng your own tools to increase its versatility,

If you have a Dremel tool and some diamond shank bits, and if you are careful, it is possible to grind a chip breaker on a hss or carbide toolbit,

Sorry made mistake 7/8 bores and Flex-Hone was 7/8 180 grit Meinhite cast iron liners Edmund

I used a Flex-Hone on the four cylinders of my Sealion 1-inch bores got a beautiful crosshatch, placed oil in a large Coffee container and used slow speed hand drill worked a treat, Edmund

I never use a file card, the only thing I use is a thin narrow strip of brass sheet about 1/2- 3/4 inch wide x .020/.025 thick just a few angled wipes on the file produces the form on the strip then it does the cleanup just fine

I hope nobody bought that Taig or Sherline 3 jaw chuck in the add for $178 you can buy a brand new one for $70

Strange that no member has suggested using a dti (dial test indicator)?

Daniel, you can try metal supermarket in Canada Edmund

Hello Brian, I was browsing today and came across your post on rocker block, it looked a very interesting engine, unfortunately, I already have too much on my plate to contemplate adding to all my unfinished symphonies, but what did get my attention was the lower line in the post, ie...

Hello John, good to hear from you, not many Sealions around that are under construction these days, I'm afraid I do not have a spare camshaft but when I made the rockers I made two identical sets, so that's what I have spare just 1 set, see attachments,

Is there any member thinking about or already starting E T Westbury's Sealion 30cc Engine, if yes please respond, I have some extra parts available that could ease machining of parts, Edmund........Alberta

When I built my Sealion 4 cylinders (cast Iron liners) I finished to size and honed with an Auto Flex Hone, http://www.brushresearch.com/flex-hone.php?gclid=CJeGkKaM_8oCFQgxaQod01ILJg placed the block in a coffee tin container fill with oil submerged the block and with the Flex Hone in a elec...

Thank Chuck, there are certainly a few operations that are causing concern, it would go a little smother with better endmills, it is a pretty good test for such a small machine, of course I have had to give it a boost by adding the wider drive belt system the thin belts just weren't up...
