    Barn Find Machine Shop

    I am interested in pictures of shops that show evidence of making a living with 100 year old tools. Mine are only 30-40 years old. I find it gratifying when I see evidence that other peoples shops are even dirtier than my own. Don't take offense with some of the responses to the pictures you...

    Advice on TRAK TRM Mill

    I have one. They have a big work envelope for the money, but I don't find the CNC aspect very helpful. The CNC part is probably more hassle than it is worth for you. When on older CNC machine like this breaks down, you pretty well have to troubleshoot and fix it yourself. Something as simple...

    Family business strategy

    Judging by your posts you are the 1% or maybe even the 0.1% of machinists with respect to talent and drive. It would be very surprising if one of your kids could match this. My suggestion is not to push it on them, if they are interested in what you do great, if not use your resources to help...

    Diaform grinding wheel profiler free to pick up in Ontario

    Hi I bought this cheap at an auction 10 years ago, it was obsolete then, it is even more so now. I never removed it from its box, I can't grind things flat let alone with some fancy profile. The new owner must come and pick it up from my shop in Kitchener Ontario. In the unlikely case that...

    Gear hobbing process question, what causes difference on one flank vs the other

    I have actually had the cost of inspecting a set of gears that make up a reducer by a third party using one of those specially equipped CMMs . It was in the range of $3000 for 5 different gears.

    Gear hobbing process question, what causes difference on one flank vs the other

    The drawing had all the gear tolerancing in the table, it is a sizeable list most of which can't be measured without some pretty specialized equipment (CMM with gear software package). Determining what values to put in the boxes is what you pay the gear consultant to use his software for...

    Gear hobbing process question, what causes difference on one flank vs the other

    Hi Emanuel The problem with the helical gears is not so much the gears themselves as the added expense of transmitting the axial forces. There are gear reducers for this application that are built to an overall higher quality level (helical gears) but that is not the part of the market we are...

    Gear hobbing process question, what causes difference on one flank vs the other

    The problem is I would have to fire myself. I am over my head in all aspects of my business, if you think my gear knowledge is wanting you would be shocked by gaping holes in my understanding of managing people.

    Gear hobbing process question, what causes difference on one flank vs the other

    Thanks everyone, I did not consider the fact that these gears were possibly shaped and not hobbed (I am a slow learner I appreciate suggestions as to which parameters to optimize for if noise is a prime consideration. This is for a medium volume ( ramps from 500/year to 5000/years), medium...

    Gear hobbing process question, what causes difference on one flank vs the other

    Hi We make the gears for our first prototype by wire EDM and that works pretty well. When we need to make the first run of 20 gearboxes we get the gears hobbed by a local shop that specializes in this type of work. Gear noise is a big issue for these gearboxes, we are trying to make the...

    Tos Hostivar OD/ID grinder for sale dirt cheap

    I bought my first cylindrical grinder (a small Italian ID/OD) 4 months ago and have found it to be very useful. Way better than trying to use a T&C grinder as a cylindrical grinder. Should have bought one 10 years ago.
