Thank you for the thoughtful reply! I'm from northwest Ohio. Because of the auto industry there is a lot of used equipment around here at least if you are looking for bigger stuff. I'm a machinist by trade, so I have most of the important inspection equipment. This is one of the reasons I...

Yep that helps, I was hoping there was a somewhat standard size people use for model engines. Looks like I'll just have to buy or make some as needed.

Thanks Brian. Is there a tooth size you find you use the most?

I've been looking into getting a gear cutting set. Is there a particular sized set that I should invest in first?

I'm building a shop\ mother-in-law suit right now. I'm excited to have my first real shop, but I'm realistically a year away from having the thing finished enough to put a shop in it. So now I have a year to try to figure out what I want to put in the thing. I have a taig lathe that I've been...

If you have dros on your lath and an indicator you can figure out the angle using a triangle calculator from online, but looks like you already have good advice on how to proceed.

I ended up changing the pulley ratio on mine to give it a little more lower end power. I also changed to a wider belt. Those too things helped a lot, but I still have some issues with low end power.

There's definitely a feel to telescoping gages, and you are right, if your hole isn't perfect you are only getting one reading. Usually when I'm using them I check the hole in multiple places to see if there is any variance. A lot of times you want to see if the hole isn't perfectly round and...

I look on ebay, and I've pick up some common sizes there. Every once in awhile you can find a couple for a decent price.

Is your motor variable?

Welcome!

It's going to be some time before I can get back into the hobby as I'm building my shop, (with a mother in law suit up top). In the mean time does anyone have recommendations for books\articles relating to engines and this hobby? Half of this will be a garage but here's where I'm at!

Nice setup, I'm in the process of converting that same lathe into a cnc. I ended up using some granite from a sink cutout as my base.

We have some 6 jaw Pratt Bernards at work and they are great Chuck's. One thing I noticed (at least on the newer models) is they grind a .006" back taper into their jaws which makes holding parts straight a pain. I ended up using a borazon tipped insert and I bored the jaws straight and it...

Wow nice job! Hard parts to make with a limited setup, but you found some nice work arounds.

Welcome to the forum!

Maybe a stiff spring. You could trap the spring with a nut so you can adjust the tension that it applies to your setup.

You shouldn't have any issues machining the material unhardened.

Here is a rough video of some tests I was doing. I switch it from the readout being .0005" per line to .0001" per line. https://youtu.be/2BnobzcxGx4

Our analog amplifier at work stopped working, and because of it's age my boss decided to buy new instead of trying to fix it. I was able to grab it before someone threw it in the trash, and with a little super glue it is working again. Right now it loses accuracy beyond the 5s on the readout...
