I'm Quietly watching this Jack
I've always bin fascinated by radial engines.
I really like that that power saw thats one bit of kit I badly need.

Hi Stew, I inherited that when the man who made it passed on, and I named it after him, he must have used it thirty or forty years before I got it fifteen or so ago. I just ran across a set of plans for a power hacksaw using a pair of connecting rods from an auto engine, to give the vertical movement necessary, and at the same time keep the bar carrying the saw frame aligned, I think its in the tools section of the forum. "Joe" is a bit loose, and needs to be set right, and watched for the first couple strokes, and some cutting oil added on occasion, but he cuts very efficiently, and rather straight, the cut shown is splitting a one inch piece of pre-heat treated 4140 in half, and the finished results gave me two useable pieces, one for the cams of the radial, the other for when I screw up the cams for the radial. I've got one of the never ending four by six chinese band saws, and while it's done yeoman's service, being almost twenty five and still cutting, it's giving out signs it may be near the end of its life. I had to spend about four or five hours fixing the bearings in place in their bores, and getting the shafts fixed, when it was brand new, as they used no snap rings, or set screws and didn't leave any room for the same, but 680 locktite has held it unmoving ever since, and all that I've done for it otherwise, is weld the blade guide plates back on their arms, and make them actually straight instead of slightly angled as they were with only one tack, as original. I sawed an anvil out of a piece of regulation railroad track once, about eighteen hours of hacksawing, a pack of a dozen cheap blades, done in by the first hour, and one Sandvik blade finishing the job and still sharp at the end of it, but I wouldn't want to ever do that again. The big deal with a power hacksaw is getting the direction of rotation of the final gear or sprocket right, and getting the link placed right, so it tends to lift the blade on the return stroke, and pull down on it during the cutting stroke. My hacksaw took forever to cut until I figured out it was running backwards, and lifting on the cut stroke. Cheers :nrocks: mad jack

Jack -
Although I've looked in on this thread occasionally, I must have accidentally missed big chunks of it. I just spent the morning re-reading the whole thing from start to finish - and I have to say just one word:
Wow! Amazing work, just fabulous....
OK, 5 words....
I love the way you can see the parts in the raw stock. I've looked at your oil pump over & over again & I just can't figure out how it works.... but I know it will, and that it'll be absolutely bob-on when it does.
:nrocks:
Artie:
So, no updates?
Brass_Machine:
Nice job! Love the frame work. You shoudl start a seperate thread for the custom bike work...
Gotta wipe the drool off the my laptop.
