I wasn't really giving precise data but the means of acquiring it. My math is probably all wrong just as the wish to help out on this forum. I need counseling too... I've made out OK for 72 years without smart ass comments from here so my help of any sort will be curtailed completely. I'm away...

All's well that ends well! Happy for you and your success... My wife has the same unique ability to find what I can't in my mess of a shop with too many projects going at the same time. I'll get frustrated and walk in the house, then a few minutes later she will walk in with the lost item in her...

NIGHTMARE!!

Appreciate the advice as I'm sure Brian does too. Your ideas are good but there is another factor that is dominate in my case. I'm recovering from knee replacement surgery - both knees - and I'm not so steady on them yet. Time flies, the wind blew and I'm not going to risk my equipment just to...

Brian, I feel your pain... We must move our home machine shop a distance of about 30 miles and I'm agonizing. I'm usually a DIY person but this will not be one of those. My largest lathe weighs a bit over 2300 lbs. One milling machine weighs about the same but for some reason I'm not as alarmed...

Your drawing shows the depth as .0627" which will not result in a .225" dia. countersink.

Trigonometry - all (most all) hand held calculators have trig functions. Tangent of 41 degrees = .869286. From there basic math. Then touch off the countersink on a suitable shim and plunge the hole for the countersink size needed. Handy for multiple holes for consistency. Your drawing shows the...

That would be considered a 'wasted spark' system since it fires the plug on every stroke rather than just on the compression stroke - unless that is, you are building a two stroker. If not; yes, that is far more range than you really need.

Well, considering the six cylinder point cam: the 'corners' of the hex are the open areas of the points. If the points are adjusted so that they open only slightly at the cam lobes, the dwell angle will be great: each lobe will act on the points during a very small angle or rotation of the cam...

Point gap is also called the 'dwell angle' or as you may visualize; the period of time or dwell time between when the points make contact and break contact. This also effects ignition timing since a close or narrow point gap has very little dell and vice-versa. There is a period of time when the...

I have the Jet version of that gearhead lathe, the 1440GH... they all appear very similar. I have been happy with it for probably 18 or so years. It has a gap bed but I don't intend to remove the gap since the old tale is that it is not always easy to get back in correctly. All lathes (I have...

Chuck (one of the good) Fellows, You have always been upbeat - we know because we have been reading your posts here and on other forums for a good while and have seen it - you're good people - smart too! You have given of yourself, share your wit and knowledge, and have given to your sons very...

Ambition, These engines are so 'low power' that they must have very, very little friction anywhere; absolutely no piston drag for example. The Poppin that I built years ago did OK at first but the more it was run - with an addition in the bore of some Marvel Mystery Oil- the better it ran. Use...

Old? What's 'old' have to do with it....? We all like new and trendy stuff but when we get serious about it, we love the 'old stuff' just as much if not more. I have the bike with this engine -R100/7 - on post #8. I build miniature engines as a hobby but it never occurred to me to take my bike...

Hey Antie, A good grade of emery cloth will not do your lathe any harm. You're correct that some of the cheap stuff will allow the abrasive to strip from the cloth. Since you are reluctant to us emery cloth, use carborundum with some light oil like WD40 - cuts fine too. Sounds like you know...

Ant, You just need to get yourself psyched up to do your job and just do it...Begin by getting accustomed to making your measurements. The old tried and true way to bring a shaft to size is to leave about .002 over and use emery cloth to put it on size.... BillC

I bought a book sized bare bones computer for dedicated use with the mill. The small size is out of the way easily with a small keyboard. That computer knows nothing of the internet and never will. I have gained confidence in the mill enough to load a program, set up the material, start it up...

Hi Bill I wonder would you mind giving me a little more detail on your thoughts about running internal oil lines. In particular what changes would I need to make to the patterns to permit these internal oil lines. I'd be happy to discuss this publicly, in the thread if you wish, but I just...

KeyCreator/KeyMachinist or FeatureCam, they are both user friendly and very professional results. Contouring is a natural for either package.

There isn't enough copper in a penny to plug a gnat's ass. They're plated zinc worth about the same proportion that a dollar is actually worth about .4¢ or less.
