Thanks Ray, I do have some professional training and experience but these photos are strictly poin and shoot with available light, hand held. No tripod. My camera is the fairly new Fuji X-10. It's pretty good with the macro. I think I could have done much better with a smaller aperture for...

Ok, so the centering operation turned out to be the easy part. I used two methods - first was the plug method - turned a simple plug as shown in Bogstandards drawing and had the cylinder centered in about 20 mins. Works quite well - but turning the plug did require a lot of test-fit to the...

Thanks for the help everyone. I think I'm going to turn a simple plug & spigot as it seems a simple and elegant solution, and it will be pretty much dead-on. The problem I see with the edge finder approach is that the circumference of the cylinder is pretty small, (1 inch dia.) and it would be...

I have the piston bore held in the vise on my mini-mill. With the DTI that I have, there is no where near enough room between my chuck (or 3/8 collet - tried that too) and the work to insert the DTI to find the center so that I can drill the cover plate holes around the circumference. This is on...

I'm posting this here as it's not something I'm selling, but thought others in the NJ/NY/CT (US) might be interested - looks to be in very nice shape with very good tolerances - not sure if the price is right? http://newjersey.craigslist.org/tls/3002216960.html This older Hardinge...

Pete, I appreciate your candor. In fact you are confirming my own belief that cheap tools are a false economy. In most cases, I try to buy the best I can afford. However, I have to say that in my short experience as a beginner machinist, I have been impressed with how much functionality one...

Cheers John, I think I'll take your advice! I've been thinking about ways to make the little launch engine kit a bit prettier. So far I've decided to replace the cheap cylinder head screws(!) supplied with the kit, with my own threaded rod and bolts - blackened in oil (tip found here on the...

I purchased one of these really inexpensive bench top band saws from HF and I've been really surprised with the performance. I did scrap the junk blade it came with and ordered some really good custom made blades from M.K.Morse (via Victor Machinery). I use it for both wood and light metal. I...

Thanks Bogstandard - that has been my approach as well, cutting a little run out space with a 1/16 parting tool I've ground a little narrower just for this purpose. The trouble is that even on the shallow side of the die, the taper meets the shoulder before the last thread can be cut to the...

I bought a cheap 64 piece set from HF and find that the dies do not let me thread small diameters with any precision. The dies cannot cut up to the inside shoulder and leave a large uncut area that makes threading bolts and precision valve fits impossible. (Yes I am flipping the die and making a...

Handbrake is great! Mac version too. It come with a number of really good presets for optimizing video - pretty much a "point and click and done" app. I use it all the time.

Ah, that explains it! ;D Thanks!

I'm really interested in taking the kids to this - but I don't see the exact dates anywhere. The 2013 dates are there, but no April 2012 dates? Unless I really am going blind. Thanks for any help!

Thanks to Garry and Topos! I will be doing some of those set up procedures this weekend. I have done some, but this is a much more helpful and thorough guide! Might even fix my compound dial issue. I enjoy working on the machine, almost as much as working with it. The more I take it apart...

Thanks for the suggestions. I'f "fixed" the issue for now with rubber O ring. Will probably add little set screw, or just upgrade the wheels altogether.

I purchased a used 7x10 Central Machinery mini lathe and I notice that the graduated dial on the compound advance spins too freely, so that it is impossible to measure advance or retreat. I have fiddled with it some, removing the dial, cleaning up the parts, (thought there might have been too...

Thank you for the kind welcomes from everyone, Bob, Tin, Rick, Dale... I originally found this forum searching for folks who had built the Elderberry Launch Engine Kit, and read every post on the Zeeprogrammer thread - all 29 pages. What I learned is that it takes a lot of patience, a lot of...

I loved going to the steam rallies and model engineering shows as a kid with my uncle in England. Really looking forward to bringing our kids to some of these shows this year - thanks for the links and info!!

Just wanted to say hello to everyone. I'm new to the art and science of model engineering. I was introduced to this world as kid 30 years ago by my Uncle David in England who had built quite a few live steam models including stationary and locomotives. Now that I have two (step) sons aged 6...
