Scott flame licker build
Bogstandard:
DKM,
I am using standard bits that are obtainable anywhere. For people working at home, I find that there is no need to go to the trouble of obtaining anything special.
Also, you will find I very rarely, if ever, quote numbers and letters etc in my posts, purely because they only confuse people even more. If it can't be kept relatively simple and easy to understand, I don't show it.
Dave and Graham,
I am very lucky, my wife cleans up after me, so as long as she can reach the shop vac, I don't worry about the mess. When I have finished with the CI maching tomorrow, I will call her in.

Dean W:
Cylinder looks good, John. It's nice to see a more experienced fellow do things the way I do it.
Makes me think I'm doing my own stuff right. : )
NickG:
Nice work John,
That bore doesn't look to me like it needs any lapping or honing to be honest.
Bogstandard:
Thanks Dean and Nick.
Dean, maybe I am doing it the same as you, rather than the other way around, and Nick, the surface finish on that bore has a long way to go, it should come up like dull chrome eventually. Then you know you have a very friction free surface, ideal for this type of engine, whereas with an ic one with metal rings, you can leave it rough and let the engine bed itself in whilst running.
Mind you I don't suppose you remember the signs on new cars from the 50's & 60's - RUNNING IN, PLEASE PASS. Even after running in correctly, 30,000 miles and it was due a rebore. Crappy metals and manufacture, even worse lubricants.

NickG:
John,
On my ridders engine and poppin I didn't lap any bores or polish any pistons and they seem to work well. I am sure you will extract superior performance but not sure how much better.
Some people seem to really go over the top on lapping in my opinion.
Good point about car engines of old, I guess a car is lugging a lot of weight around though, they have serious stress on them and at an average speed of say 30mph that's 1000 hours of running. I doubt my engines will see more than 100 hours of ticking over over the course of my life!
