    Miller Dynasty Vs. Lincoln Aspect

    A buddy of ours is shopping for a more powerful welder. He has a Dynasty 210 which works well but he's running into jobs that need more amperage. He has actually ordered a Dynasty 400 from our local welding supplier but they're telling him that there isn't a single unit available anywhere in...

    What Would This Backplate Be Used For?

    Picked this backplate up with some other stuff. I've never seen anything like it before. Does anyone have any idea what it might have been used for? It's a D1-6 size--those pins are 3/4" diameter and about 3" long. Looks to be a production piece, not something home made...

    Difference Between BSPF and BSPP Threads?

    I have some sight glasses to install and but won't actually have them for a couple weeks. In the meantime I need to finish the parts so they can be sent out for paint while we're waiting. The catalogue lists them as having a 3/4-14 BSPP thread. All the taps I can find locally are listed as...

    How Good Are Noga Style Indicator Stands?

    I have a couple Noga style indicator stands--both are imports, one is an Insize and the other an even cheaper import acquired from Princess Auto. Build quality of both is really quite good and I love the convenience of how they work but when I use them both seem to be just a bit "springy", for...

    A Question About Surface Plate Support

    We have a customer who wants us to build a stand for a 24" x 36" surface plate that they've purchased. I'm familiar with the principle of Airy points but what I can't seem to find is whether the three mounting points should be rigid or if it's better to make them swivel so they make full...

    Mystery Metric (?) Thread...What Have I Got?

    I have to machine up a simple aluminum coupler for a small Mitsubishi marine diesel exhaust manifold. It's essentially a threaded nipple used to connect two parts but allow rotation for positioning. Everything on the engine is metric and when the customer brought me the parts he told me the...

    How Much Interference Fit For A 5" Bearing?

    Title pretty much explains it. I've machined up a replacement housing for a single row ball bearing on an old Howard Rotovator. Right now I have an interference fit of about .0023" which may be a tad tight. Being that close I'm reluctant to make another pass as I definitely don't want to go...

    Beat Way To Drill/Tap 3mm Holes?

    I have a project that involves drilling and tapping twenty 3mm x .5 holes in the back of a 10" x 17" aluminum heat sink. Because of the alignment of the holes to the fins on the opposite side some will be through and some, where the hole lines up with the fin, will be blind. Screw length is 5...

    Fonts for laser cutting?

    I need to make a sign for a customer and I want to have it laser cut. I've done this before and to get a stencil style font I had to draw the letters out myself--doable but a lot of work. That was 8-10 years ago and I'm thinking that, given the proliferation of plasma, laser and water-jet...

    Question About Cast Iron Back Plate...

    I have a 13 x 40 lathe with a D1-6 spindle mount and I would like to mount a nice little Bison 6" 3-jaw chuck that came on a rotary table I acquired in a separate deal. To mount the chuck I planned to use a backplate that came as a spare with the lathe. I cleaned the back plate up and mounted...

    Reoairing a Nider Drill Press...

    Friend of mine has a Nider (Swedish) gear-head drill press that has taken to slipping when too much load is applied. He's pretty sure it's a broken shear pin but he has no manual and is not sure how to attack the gear box. I was at his place this afternoon and we tried to get one half of the...

    Source for 1/16" SS wires/pins?

    We have an ongoing job where we make SS fingers out of 4" lengths of 1/16" SS spring wire. Not a high volume thing; we make an average of 2 batches of 1000 pcs. per year. The material is run from a coil and cut and straightened--pretty straight forward. We've been using a local supplier and...

    Best way to mill phenolic carb spacers?

    Just got a call from a customer wanting to reduce the thickness of a phenolic carb spacer from 1/2" to 1/4". I'm concerned that simply clamping them in the vise on parallels will result in the middle bowing up under pressure and leave me with a low spot when the pressure is released. I thought...

    Milling Machine Spindle - How much runout is OK?

    I have a 20+ year old First LC18 VHS milling machine which I acquired used about a year ago--it came with an NMTB 30 taper in the spindle. A few months ago I picked up a used Jacobs 14N chuck mounted on an appropriate arbor. I hadn't gotten around to using the chuck until recently and when I...

    Tips for threading 1/2" alum. pipe?

    Have a request from a customer to quote on threading both ends of 500 pcs. of 1/2" alum. pipe. No special tolerances; just a good fit in an elbow and/or a coupling. We have a Rigid 300 threader with the proper dies so I know we can do the job; I'm just wondering how we can speed it up a bit...
