We have been getting hits by spammers using personal messages for about a week. Unless you report them we Admins don't know about them so can't do anything. Please read post #2 on this thread from a few days ago on how to report them so we can ban them. We have also taken a few other step to...

Assuming that you have not used one before, here are a few quick notes. 1. The blade must cut on the pull stroke. The teeth face the handle. 2. Select a blade that will give you about 2 teeth in the thickness of the metal being cut. Less than 2 teeth and the blade will grab and the blade...

A piercing saw is commonly known as a jewelers saw. Look like this? Gail in NM

We have had a rash of spam private messages. Some one registers, waits a few days then sends out a small pile of spam messages as private messages. We ban the spammer and lock then out as soon as we find out about it If any one gets a spam private message, please report it to the...

Very nice engine and excellent workmanship. :thumbup::thumbup: Gail in NM

Great news. It counts, you have a runner. :thumbup::thumbup: Gail in NM

I find that they can be useful, mostly for comparative measurements as in multi-cylinder engines. I have built two compression gauges. Here is a simple one that is useful with engines of at least 5cc displacement.The problem with getting any absolute measurements with small engines is the dead...

Glad you have good parts. That's always the goal and what ever gives us that result is the right way for us. Gail in NM

Gordon, I misread your first post and thought that the MFG was saying that your DXF file was the problem., so what I suggested was just to verify thet the DXF file was correct. If you scale the part as you described the OD of the part will be correct but any bolt clearance holes will be over...

Gordon, It sounds like the plotter software has a bug. DXF files are well defined and I don't know of any CAD that outputs a distorted DXF file. But here is what you can try that won't cost you any stock. Draw a circle in your CAD of known radius, say 1.000 inch, and a known center. While you...

Piston_Broke, Since we have disculssed 3 engines here are the links for all 3. Tiny 4 cylinder in line http://www.burleighmachine.com/ Plans for sale $40 Webster http://www.john-tomcom/MyPlans/SteamPlans2/Webster%204Stroke%20Plans/Webster%204Stroke%20Plans.zip Tiny single cylinder...

I have no real idea what the market price of a Tiny4 engine would be. As a guess I would expect anything under US$ 3000 would be a bargain. Way too many variables to consider. You certainly have equipment suitable for a build, but it sounds like you need to gain some experience. Keep in mind...

Mark, Kel's plan set is very well thought out and of top quality CAD work. 32 pages long with a fair amount of notes. I have not built the engine but I did build the block and a few of the other parts a few years ago. I gather from your previous posts that you are qlulllllllite new to model...

Brian, To further muddy the waters a bit for you, consider the cam follower shape. The Webster uses a flat cam follower. The Kerzel uses a roller follower with an 1/8 inch radius. Your analysis of valve motion appears to be based on using a point contact follower. When doing a math analysis of...

I have been very happy with the 1144 that I have bought from Speedy Metals. http://www.speedymetals.com/c-8238-category.aspx I have bought 1144 from thm about 1/2 a dozen times. I generally buy my 1144 as TGP ( Turned Ground Polished). TGP has a diameter tolerance of *0/-0.001 in under 1 -1/2...

Sorry Brian. I should have explained in more detail. Thanks to Journeyman for doing my job. Gail in NM

Spammers have v\been busy lately. They get very creative about getting around the various systems that iev andAngie implements to keep them out. She gets up to 100 BOGUS registrations a day that never get to post. Herbiev and I field the ones that do get by. The other Admins join in when they...

It has been no problem for me for the last day. I have checked in 8 or 10 times as there is a thread I am following. Just checked now and it is OK. Gail in NM
