    Factors affecting choice of wheel width.

    Like Buck said, you have to figure out how you prefer to grind first. If you down feed .0002 and step over 1/2", then the 3/4" wide wheel might be useful. Like Buck, i am mostly working with situation where " a fair amount" has to come off, but not so much as to waste time milling it first. So...

    JJ Smith Belt sander issue.

    PS: unless you have gone over the machine completely and adjusted it up from first principles, the above might or might not be a band-aide. Is the contact drum true? How about the idler rolls? Are all the above adjusted in their bearings to have parallel axes? (Or possibly with wear...

    JJ Smith Belt sander issue.

    Do what M said and take the belt off, then put your hand in front of the air signal on each side and see if the piston cycles freely. Try it with a finger directly over the port, then try it out at about the distance the belt would be running as is approaches & passes the port. When i got my...

    Whitcomb planer

    On mine the bolts in that area only hold brackets for the overhead drive. The threaded holes are also not quite like yours, in that they are radial along the circumference of the curve. (rather than square/parallel to the table) The brackets on mine are probably shop made, although...

    is the field of robotics and automation worth going into?

    One thing that does seem to happen with all the pissed off and laid off brilliant engineers who would do the work in their basements whether employed or not, is that they end up combining and starting new products, services, and industries that innovate across the board, and sometimes even...

    What I Am Currently Building

    I deleted some rants and gave some warnings. He must have accrued enough warnings here and elsewhere to get the boot. Gonna lock this now, should have before setting off this morning. It's not serving any useful purpose.

    Small punch milling for horology

    It sounds like the task is for fun and education? So you don't have to exactly replicate ancient industrial methods. I've made lots of simple punches from hardened, usually M2 steel blanks or busted endmills and such. Only a few with mating dies, for simple things. It does make sense for a...

    college versus trades

    Most kids have not been exposed to enough, to actually know what they want to do. If so, great, chase that path! If not, try all sorts of options and experiences, and keep getting educated including armed service stints, peace core, etc, as it suits the trip until something grabs. I know that...

    OD Grooving Tool Recommendations

    Thinbits? (Kaiser) No idea how pricing compares. All my holders, and boxes of inserts came in a tray in the bottom of a box of Hardinge chucker tooling. I like how the gang tool holders set up; but very little actual use. smt

    Is that 25" or is it 1/4"? mm's ? Inches? Not picturing this very well - so the slot is closed on both ends? smt

    Are there any tricks to planing quartersawn Sycamore?

    I love that stuff! My memory is that it planes fine until it doesn't, but that the issues tend to be small pockets that suddenly pull out, rather than going bad all over as a lot of wood does once a wild grain area is encountered. The only sort of recent projects have been calibrated in the...

    Milling slot in 316 s.s.

    how many/how long? think i'd re-grind a saw to .047 if any quantity. Re-grind wood-cutting wing cutter for "a few" For one only, i'd plane it in the shaper...... smt

    Custom Cast Iron castings - any rec’s?

    I've never used them, but several friends including Dave Richards routinely use Cattail Foundry. They seem to be responsive & relatively fast, and will cast from existing parts. All points made by OP's in this thread about you cleaning them up, filling holes, smoothing/blending surfaces, etc...

    Oliver patternmakers mill

    Nice/interesting work. Hope it works out well for you! Any special reason to land in Des Moines? Can't tell from pix - did you bring all your machines over, or will you be starting up again with locally sourced machinery? I'd love to ski some of the areas in Bavaria, but that is probably...

    How the Artemis 1 Rocket is made a good example of the US and Europe building in cooperation together.

    What a well written post. The US government essentially followed this plan nearly nationwide after WW2. During the 50's and early 60's which most people "remember" as a golden era, the jobs, technical development, and production that occurred was not completely unrelated to the fact that the US...

    Northrop Grumman lousy machining quality

    Sometimes true, sometimes not so much. But from the bean-counter and executive suite, it takes skilled specialists out of the equation & removes an element of floor workers control. Sometimes just defining a regular time-per-part is the advantage for putting together proposal docs. The skilled...

    Re-machine surface on a 5 feet square Acorn welding table, Greenville, SC.

    A versamil is capable, but you would have to position it multiple times. Maybe also shim depending on how flat the low section actually is. It would be easy to bolt down through the stake holes, too. Cut the plate in half & it will fit a lot more planers. :) With 4 repositionings/2 each side...
