Hi CS, Those gears look great! I like the y c-sunk screws on the water pump. Very clean look. I am excited to see more. The bushings which were wearing out were 1/4 the thickness of the ones in the plans, and they had no oil passages. The plans have the heavy duty bushing in them, and so far I...

Hi Edi, The method you describe for making the crankshaft sounds a little hairy. (But that's just me) It works fine for the camshaft, but the crankshaft journals will need to be vary concentric, with a smooth finish. I don't see a problem with making the main journals larger in the block, as...

Hi Edi, I love the pictures, keep 'em coming! I do like the oil pan you made, it looks great! I will be watching for sure. Kel

Congrats Jason! Well Deserved for a beautiful engine. Kel

Could you make it out of sheet brass, formed and soldered? Kel

Hi Herbie, With the jaws out, turn the chuck key counter clockwise, and you will see the scroll turning. Keep you eye on one of the empty jaw slots and look for the end of the scroll at the outermost part of the chuck. Let the end of the scroll go slightly past the slot and then insert the #1...

I agree, 304 is a machining nightmare. Do whatever you can to keep it from getting hot. I generally peck drill 25 thou at a time with a 1/4" bit. I just worked with copper for the second time at work today. I got to make two copper bolts 1/2"-20 thread, turned down from 3/4 by 3-3/8" long. I...

Hello Dave, I have been using Solid Edge 2D drafting for 2 years. I find it very easy to use, and it has all the capabilities required to make professional quality drawings, and easy enough to create a quick doodle in the shop. You can download it for free, 100% unlocked from their website...

Thanks again guy's, for your kind comments. Kevin, We are using solid works, and I am not sure of any version number. I wrote my first lathe program after work today, just a simple OD turning from 2-1.5" diameter. I will be bringing the text file to work tomorrow to see what 30HP of lathe...

Thank you all for your kind comments, and words of encouragement. I know that I have a great teacher there to help me get where I need to be, and I will be sad to see him go, but he won't be to far away so I will still have access to his wisdom, along with the great help I receive here, I am...

This story starts over a year ago with this thread. http://www.homemodelenginemachinist.com/index.php?topic=10623.0 I have been employed there for almost 4 months now, I have enjoyed every minute, and have been learning new interesting things every day. I LOVE IT! Last week my boss brought me...

Thanks George. Teflon id the one thing I have not tried yet. I have thought about the machinable ceramic, but ya, it is quite expensive. A guy at work found a product from http://www.cotronics.com/vo/cotr/ that might do the trick. One of the adhesives I think (I can't find the exact one on their...

Thanks Doc, it is nice to know that the Delrin is working for you. With my Tiny Inline I used Delrin for the spark plugs. However, with the hard use, high rpm and load, the delrin would burn away. I have had better luck with corian, but I am currently researching ceramic paste material, and...

Those governor parts look great Doc! It is nice to see another Hit&Miss version getting built. Hope you feel better Doc, looks like we are in for some more nice days, that should help. Kel

Hello dgjessing, ABS stands for absolute. Lets say the bottom left corner of the part is 0-0. You would find these edges and then zero the DRO. This would be done in "ABS" mode. Now lets say you need to make a 2 holes 1 inch apart, with the first hole .5" from both the X and Y. You would move...

Brian, which cutters are you looking at to get the $400+ price tag? From what I seen, cutters between 20 and 48 DP (or pitch diameter as they refer to it as) are about $31-$33 US a piece. (Not a whole lot different in Canadian Dollars) If you buy one, they should :hDe: send you a coupon for 20%...

I have a full set of 48DP gears. Sometimes I wish I had a smaller DP set, but this is pretty much the smallest that is readily available. a 12 tooth gear is about .291" in diameter. I have also made 12 tooth 45 degree bevel gears with the same cutter and they ended up just under 1/2" in...

I like this engine design Steve. how big is this going to be? I am curious as to the placement of the rockers being perpendicular to the cam lobes. Is there any funny stuff involved in the design of the cam and or tappets to make it work at the angle? I have seen this before on motorbikes...

Great job on the Tiny so far Doc! I too am very partial to this engine, although I don't posses a stockpile ;) I would like to build another one, or two. Gails "Hit and Miss" version is really neat, and its so darn........well.......Tiny, you cant help but want more. Kel

Hello and Welcome plumbman! I have Both those machines. The Mini lathe you are referring too is a great machine. It comes from many different distributors like Grizzly, Harbor Freight, I got mine from a Cummins Traveling tool store. I have been pleased with it and taught myself how to turn...
