    O.T.- Can you help me with a hydraulic system mod?

    I have a PTO driven wood chipper with a self-contained hydraulic system for the infeed roller which is driven by a single hydraulic motor. I need to tap the pump output to run a low-pressure (200 psi), low flow auxiliary cylinder, but when the infeed roller is free-wheeling (no load) there is...

    Anyone dealt with Heidenhain re: warranty service? Not impressed with them at all..

    Last year I bought an Acu-Rite M203 series DRO through MSC. (I'd have much preferred another 200S like I've been using for over 10 years without a blink, but like all good things the 'new, improved' version is all that's available). This fancy 203 display went blank-screen about a month ago...

    Metallurgists: I need advice on material selection to avoid stress-fracture

    Good Morning. At my place of employment we fabricate a product that is exposed to all manner of climatic stress. This particular query relates to wind-induced cyclic stress on a solid mild steel/stainless steel shaft. I cannot post a photo or drawing of the actual product, but I can give you a...

    OT- What is in PVC smoke/soot that gives bare cast iron and steel color?

    Had a small fire in the shop New Year's eve. The fire was contained entirely in the top of a good-sized toolbox but the smoke and soot blanketed everything, upstairs and down. After cleaning the machines, the bare steel and cast handwheels, etc. have a soft golden look as though they'd been...

    OT- To my friends in the UK: How much is a pint?

    Since a 'cup' of coffee can be much less or much more than 8oz., how much beer do you get when you go to the pub for a 'pint'? (Yes, its a slow day today!)

    What is the bending strength of 2" OD 304L tube; .065 & .120 wall?

    I've been asked to fab a set of 'adult-sized' monkey bars for a Christmas present. The user is 6' 2", 180lbs. They'd like the run to be as long as possible, up to 20' but at least 10'. I've requested a quote for 2" welded 304L round tube in wall thicknesses of .065" and .120". Cross bars will be...

    Potential 'hot spot' in shop wiring during TIG weld

    Had another senior moment this morning & forgot to attach the ground clamp to the welding table/workbench. My table is on casters, all steel and has multiple 120V outlets around the perimeter which are supplied with a 12ga cord from the shop wall outlets. The welds (aluminum @ 150A) were short...

    How does the Rear-Drive go together?

    Howdy. I am working on a very old (1929) 9" with back drive. I think I have all the castings but not all the linkage. Could someone post or point me to detailed photos or illustrations of the back-drive from various angles? I've looked through hundreds of photos on this site but naturally...

    Hi- Can someone please help with my 1929 9" gear train configuration? Thanks!

    Hello folks, I've got a Model 82-YB, SN 41755, with a date cast inside the bed of 2-11-29. There is an exact illustration of my lathe in a South Bend flyer from 1927/1928. Here's what has me confused: With the drive gear assembly engaged, the gear cover doesn't line up. The sliding gear shaft...

    Unfamiliar Boring Head Shank Add-on: What is it?

    This is a recent eBay purchase. I thought when I got it in-hand I'd be able to figure it out, but I can't. The boring head is a standard 2" Criterion, the shank a straight .750 Criterion. The part in between? It has an index mark on the top flange, a scale 0-30 in the middle and a lock screw on...

    OT- Ever had V-belts shrink?

    I put two automotive-type belts on a machine with a slip/tensioner engagement mechanism. The drive-to-driven pulley distance is fixed, the pulleys are dual groove cast iron. The belts went on easily and had plenty of slack when 'disengaged'. I ran the machine (an Ariens Rocket tiller) hard for...
