Looks like you found the issue. I might mention that we ran into a bad batch of standard (non tapered) dies at work. They came in an imported set and would tear up threads (in aluminum) pretty bad. For a while I thought it was me but buying a good quality die proved that wrong. Just...

Very nice work. I can remember years ago throwing out a bunch of high end air bearing spindles due to a change of processes at work. At the time I could not have imagined a use for them. Yours of course is a bit different in application but nice just the same. Do you have any...

With respect to forced air, back in my zinc foundry days just about every burner and furnace was operating with some sort of air supply. That could have been a fan based burner unit for the zinc pots or point torches for heating specific parts of the machine. Your weed burner is most...

to late to edit my post but here is a visual of that manually operated "mill": https://www.amazon.com/Whitney-Veritcal-Miller-Profiler-Instruction/dp/B005F1AYEG. Officially it is called a 2 spindle profiler. Pretty cool as tech from the 1940's.

I'd consider this as a way to make a pattern in a softer material like lexan or maybe even aluminum with hand tools. Then use the pattern in tracer mode on the mill. Back in my younger years I got to work on a "mill" left over from WW2 production that was a manual tracer mill. It might...

flat chat? <--- not familiar with that one. As for your machinist friends complaining about stress on a machine, it is hard to say if the complaint is valid at all. Just because you have a machine running at max RPM with a good feed rate doesn't mean the machine is overloaded in any way...

Most of my use for wood has been to straighten lead screws at work. It really doens't take a lot of force and the wood prevents damage. It is real easy to over do it in a mechanical or hydraulic press. The biggest problem with a crank is figuring out where the distortion is coming from...

Sadly I don't have one but have seen them at auction. At least I think it was a V10, it is a very impressive, high quality machine compared to my little import 9x20. At least it looked that way at the auction. In any event does somebody with a screen name like "Packrat" really need a...

This kinda makes me sick because I see what leaves my plant for the recycle yards. Unfortunately once it leaves the plant nobody can get access to it. I’ve seen things like table saws go out the door with the no you can’t have it reply. Something about liability. Waste in modern...

For those of you interested Gleason Works still operates in Rochester NY! I know that doesn’t help much as nobody will be buying a new gear generator from them. At least not for the home shop.

Bad communications on my part, sorry. I'm not sure where you are form but a 2x4 is a long stick of lumber commonly used in the USA for studs. The lumber is relatively strong but soft, thus you can use it bend or spring shafts and such back into straightness. Basically you find a pivot point...

Even if you machine the crank from bar stock some distortion is likely to happen. Bar stock that is stress free can really help here. So part of the skill comes in straightening the crank. Remember the cranks can easily be bent due to their size, you cna do it with a 2x4 if you really...

nice upgrade. DRO's become second nature real quick and eliminate the need to do a lot of math at the machine. The only way to a better up grade would be to go CNC and many people simply don't want to be bothered. By the way a nice little mill.

Never seen anything like it. However it looks like a long travel dial indicator, with coaxial hands. Interesting design really, but this is the first time I've seen anything like it.

Refactoring old parts is a tried and true method to solving a problem. If it works for you go for it. As for your original plan making a cutter really isn't that big of a chore. However I would go to larger T-Slots and just make the proper T-Nuts for those slots. Why? For a milling...

Looks like you have the boring head going to a good cause anyways. I've never been to England (UK), interesting place but I'm beyuond long flights for travel anymore.

yes you can. MSC has around six different types. A bit expensive but they can be found through numerous tool suppliers.

Yeah the pricing can be a killer and frankly you want to buy decent quality taps and dies. There are lot of threading videos on line but a recent post by Joe Pieczynski over on YouTube covers a technique he uses when a shoulder is involved. Joe certainly has some interesting videos and they...

I'm not sure I can hit anything new here. In any event as pointed out cheap tap sets are next to useless, junk really. They aren't even worth the money spent on them to get a tap wrench. Case in point just today at work I ran a die over a piece that came out grossly undersized, the cheap...

Which Manchester? Manchester in upstate NY (wishful thinking on my part)
