Re: head gasket leakage question

I am surprised nobody mentioned this, do a compression check, most four cyl engines will leak in the middle 2. Pressurize the cylinder with the lowest compression with the radiator cap off, bubbles in the radiator and you have found the problem. With aluminum heads you have to surface grind. I have ...

Re: Cheap DRO

I am interested in how the cable connects to the encoder. 2 wraps around a carefully made pulley? Almost sounds like a gear (say 100 teeth) and a simple counter could be slapped together easily. Or how about a poor mans' trav a dial? Just thinkin out text.

Re: Counter-acting pitting in boilers

Good Stuff! The problem with alternative fuels has already been solved by conventional fuels, energy density. The world uses a tremendous amount of fossil fuel energy in a day, and it is in a convenient form. Batteries, hydrogen, and particularly fuel cells either can't compete cost wise or bang for...

Re: Scroll saw, jig saw?

Another trick is to take a scroll saw that uses pinned blades and put a section of hacksaw blade innit. I drilled the holes for the pins with a worn out dental carbide bit that a buddy of mine's wife who was a dental assitant got. Slap the bits in a Dremel and drillin holes in a hack saw blade was e...

Re:Apology Accepted

Each tooth (for a bevel gear) is a tapered form. The way to make a gear wheel (bevel or otherwise) is to make multiple teeth and "glue" them in the right places on an appropriately shaped hub. Take some paper and make a rubbing of the large (outside of the gear wheel) tooth and then with another pie...

Re: GEARS Exhibit in Portland Oregon

O please lessen my experience! I have none in that area, all I know is that the fellow said it was from a heliocopter, put out approximately 100 hp and weighed about 100 pounds. Made lots of noise and would look good on my coffee table (if you have to ask then you don't understand).

GEARS Exhibit in Portland Oregon

I just came back from the GEARS exhibition in Portland Oregon, even met an old friend from years ago. I am sorry that I don't have a camera, lots of nice exhibits and it was well attended. Ij even got to see and hear (ouch) an APU (small jet engine) from a helicopter in the back of a pick up. Those ...

Re: MAP-3 diesel......what does it run on?

Model airplane diesels are great fun and it doesn't take a rocket scientist to run one. I mixed my own fuel out of starting fluid, kerosene, and motor oil. Commercial diesel fuel works better because it has amyl nitrate in it. I could write instructions but the instructions for running one can be fo...

Re: Pi Tapes - O/T

Thank you all for this discussion. Thanks especially to Harold for having saved me potential frustration for scrapping something and I did not know why. I use calipers because they are inexpensive, I have some mikes but didn't want to use them unless for the "special projects". I have tried some pre...
