Has anyone built this engine? If so, I have a question. I am in the process of building a "doubled up" version of the engine. The original plans say the plug holes, which break through the combustion chamber, should be drilled to where the bottom of the hole is .025 from the seat of the...

I've recently started the whittle v8 and am doubling the size. I saw one poster on here that started doing the same, but he hasn't posted in his build thread since late last year. Has anyone else attempted this project? If so, where did you obtain the bearings and gears, and what size should...

First off, I'm a newb to machining and model engine building. My question is what is the best approach to turn a smaller diameter in between two larger diameters (two shoulders)? For example, a journal on a crankshaft. What is the proper tool to use? A parting tool? If so, how do you get...

My cousin just sold his 9X20 Lathe and is looking for a 12X36. He is located in South Alabama. If anyone has one for sale in that general area, please let me know.

My cousin has found one for sale. It is a 12X36 (model #1236). The guy told him it was made in the 80s. Are these considered good machines? From what I can gather, they are Taiwan machines. Is that correct? Are they better than the Chinese machines? What would this particular machine be...

Anyone know what I could expect to pay for a good used Starrett dial test indicator that measures in tenths, and in reasonably good condition? Something like this one sold by LMS: http://www.littlemachineshop.com/products/product_view.php?ProductID=3168&category=

My cousin ran across an old Sears Craftsman 12X48 Lathe, model 101 (I believe that is what he said). He says it appears to run smoothly and is in what he calls "overall pretty good condition". Sorry, wish I had pictures to show, but I don't. It also has a 4 jaw chuck and steady rest with it...

Very much a newb here, and was wondering how you go about milling a smooth radius, such as the front bearing housing on the Whittle V8 in the second post of this thread: http://www.homemodelenginemachinist.com/f31/whittle-aero-v8-wip-4583/index45.html Looks like he's using a rotary table and...

I'm new to this hobby and was wondering if, in addition to safety goggles (which is obvious), should a dust mask/respirator be worn at all times while machining metals? Are certain metals hazardous when machining them? Most of the safety rules in the shop are common sense (turn machine off...

Has anyone installed these on their mini mill? I'm thinking of installing one of these on all three axis of my mini mill, and was wondering if anyone has gotten any good results from them. Would also love to see some pics of installation...

Newbie to machining here. I need to drill a precise hole 7/32" in 6061 aluminum. Will be using my mini mill. The dept of the hole will be about 2.8". Any suggestions on what drill size I should start with before the reamer? And what mill RPM should I use for both the drill and the reamer?

Anyone have any recommendations for a 3-axis DRO for the sieg mini-mill? I know LMS carries them for $700+, but I was hoping for something more inexpensive than that.

I'm a complete newbie, so forgive me if this is a stupid question but.........How do you go about drilling holes to precision? In other words, if I have plans that call for holes that are .208, .157, .123, etc., and don't have drill bits for every size, how do you get the holes to the exact...

I have the HF X2 mini mill. After I convert to the belt drive, what is the maximum diameter facemill/flycutter that would be recommended? I know out of the box, 1" is the maximum recommended, but with the belt drive, I was hoping to use one a little bigger.

I am just starting up this hobby. I've recently built a nice shop in my backyard and am just starting to purchase the tools I will need to build model engines. My first purchase was the Harbor Freight x2 mini mill. I also bought one of the tooling kits from LMS that contains collets, end mills...
