Re: Milling vise choice

Ok Thanks, good info. I'll keep watching for Kurt. I have 17.5" Z travel. Question, With that much travel why would that be a concern? I woud'nt think one would do any milling using a vise to hold down a tall piece of work with so much distance between cutter and area clamped. Not very much rigidit...

Re: simple qick change tool post

Why is this considered a QCTP? Doesn't look like it would be very quick to change a tool Maybe quicker than an Armstrong?

Re: Thinking about cnc

There's a PCNC1100 at the local makerspace that a few people run. There are some shortcomings, but it sounds like most of that can be worked around. One thing somebody mentioned a few days ago when we moved it was that for the current price, a person can get a used Haas that is far more machine. I u...

Re: fixing go cart for next generation

I'll add that even in such things as an electric motor, you'll often find wavy washers keeping pressure against the bearing at one end to keep axial slop to a minimum. While it doesn't provide significant preload, it performs the same function by keeping the play out of they system.

Re: fixing go cart for next generation

...Putting pressure against the two inner races of the ball bearings just seems wrong. Perhaps drilling the axle and using a castle nut is the answer and not putting much if any preload on the bearing is the way to go. Putting pressure against the inner races is exactly what preload is. If you want...

Re: fixing go cart for next generation

That's not how it works. The way it is installed is exactly how bearings should be. How are you going to prevent wear on the sliding surface of the outer race vs the washer? Another bearing?

Re: fixing go cart for next generation

I'm having trouble picturing what you want to do, but it sounds like a bad idea. The way the bearings are preloaded is the same way they are done on automobiles. If you don't want the bearings preloaded, just use a nylock nut and leave it loose from the bearings. I can't think of a good reason to do...

Re: Brico Band Saw

Dang! Talk about reviving an old thread! That style of saw is everywhere. Many different variations, but one thing they all have in common is the gear eventually wears out and it's near impossible to find parts. Different brands used different tooth pitch and count so if you really want one, you'll ...

Re: Eye bolt rating

Ended up not using eye bolts at all. No time to go look for them. It also started raining, so I didn't want to drag the plasma cutter out to cut lifting eyes. So, I just bent up some 3/8" round bar and welded it to the ends of the tubing. Also welded up a spreader to hang the machine from. The round...

Re: Engine hoist capacity beware

A friend and I were discussing today the woes of these little machines and one of the issues is that there is enough slop in the joints that a load can swing a little bit, but still pull the boom off center a ways. Mine, the boom goes from center to several inches to the right, when extended. Static...

Re: Engine hoist capacity beware

Those engine hoists work well at what they were designed for, re/re automotive engines. Where they run into real issues when used in a home shop is getting the suspended load up to and onto at least the center of a bench top if the bench has a base that doesn't allow the horizontal legs to roll und...

Re: Engine hoist capacity beware

I've started a design that should be far stronger overall. Bigger, fixed wheels up front, pallet jack-like steering, heavier wall tubing.
