They get brighter to the point that they burn out. An LED rated for 1.5v will probably work ok at 2v but have a limited lifespan, and will pop instantly at 9v. LED circuits rated for 3v or higher tend to be using driving electronics to maintain a steady output as the battery dies, or are...
I don't know exactly, but just a thought. Considering that typical LEDs of that type require 1.2 to 1.6v, and that there's no funny electronics in side (it's just making a connection between an LED and a battery, simple as that) I don't think it's very likely that it'll be 3v. It's difficult to...
Cheap calipers tend to be lacking in the temperature compensation and low battery protection as well. As long as you're familiar with those effects it's fine though. Even taking cosine error into account, it's still significantly more accurate than trying to split the 0.01" (the smallest...
Pretty simple.
It's just a plate with a pivot that holds any gear in mesh with the gear train as an idler. I even put a key, so that all of the wear is on the pivot, instead of the gear. It just swings to adjust for different gear ratios. Just use any gear there to reverse it. The top and...
Indeed, I rarely use the autofeed myself unless I'm doing something really long. I'm pretty happy about the machine, except for the odd graduations on the tailstock ram. I can never get my head around how much advance is happening per 5 or 10 ticks. I've been thinking about how to add a caliper...
A few things have been delaying this project.
1) I needed to make some tools to radius the under side of the head
2) It's summer and I own a motorcycle
But I've made a little progress on a radius tool. I wanted to make it fit many types of jobs, so I needed a lot of adjustability and the...
Brian, Craftex B2227L? If so, you can turn off the lead screw with the handle to the left of the apron, engage the leadscrew with the apron leadscrew engagement, and move the carriage with the crank at the right hand side of the tail end for much finer feed and dial graduations.
I imagine you...
I was able to make an 1/8" HSS parting blade into a bifurcated tool for this purpose and make it perform cutting sideways by making a toolholder for it instead of using a standard parting blade holder. Rather than clamping down like most parting blade tool holders do, I cut a slot in the side of...
