Thanks, guys!

Hi Emgee,

I assumed that 1/4" steel wasn't thick enough, given that the cast iron back plate for sale is 5/8" thick with another 1/8" for the chuck register.

Mike

The $45 price for a cast iron chuck backplate to my door has me wondering if I would be fine welding up a couple pieces of 1/4" scrap mild steel and then stress relieving it in the oven for an hour or so. This will be for mounting my 3" mini-lathe chuck to my 4" rotary table. Any reason not to do this?

Mike

My basement workshop is 3m x 1.4m and has plenty of room for my 7x14 mini-lathe, mini-mill, and a drawer unit next to the lathe. It'll be even better when I build a new stand for the mill to include multiple drawers instead of the current single shelf. Some tasks get done outside, of course, but like Andrew said...better than nothing!

I have several sets of cheap Chinese bits that cut poorly until I properly sharpened them. I have a set of HSS bits that I bought decades ago, made in West Germany (remember that?!), that cut really well. Does the package mention material and Country of Origin?

Only if driving were a legal right.

Out of curiosity I tried WD-40 and it does not remove Dykem.

Mike

Useful...And humorous!

I should point out...While I do use isopropyl alcohol, acetone will remove Dykem more quickly. I just don't like the smell of acetone. I have both. Acetone is pretty good at removing stickiness from labels and such, where isopropyl alcohol isn't so good. And acetone is also known as "nail polish remover". The store where I buy it has it as 100% acetone, without the nail/skin conditioners. (Interesting fact: Your body actually makes acetone in small quantities.) Acetone will also cause temporary skin cooling...If you use it outside when it's bitterly cold and get it on your fingers you'll not want to do that again. There's probably potential there for nerve damage if done too much. It may be a trigger for those who get Raynaud's syndrome.

Does that mean you can't buy isopropyl alcohol at the local pharmacy where you live?

Here in the US I've only seen as high as 91% at the pharmacy. I think 70% is becoming more typical. If you do any electronics soldering, then get the 99% isopropyl as it cleans soldering flux better (less water).

I can confirm that isopropyl alcohol does work; it's what I use. Acetone also works. Both of which are safer than brake cleaner...which will also work, but is nasty stuff.

Nevermind. I got ideas from this thread:

Hi guys,

I'm trying to understand how this power feed clutch works so that I can add one to my own power feed that has no clutch. The clutch itself has no power and is just activated with the rotation of the knob. The right side of the clutch contains a pin in the bore that engages a slot in the table's X feedscrew. The left side of the clutch has a D-shaped bore that engages the motor shaft. How do the two halves engage? Would there be a yoke involved?

It's a bit unfair to expect anyone to match a huge corporation like Amazon. I wish Amazon would disappear altogether.

Is this it here?...

I've been watching a bunch of cosmology videos recently. I like the idea that the creation of a black hole in one universe is the big bang in an offspring universe.

I'm in America and I don't know why anyone would buy a Hershey chocolate bar...They're disgusting.

That's my thinking too. I also think there are people who are listing books available at the library, which they then steal when someone wants to buy it from them.

Wow, I didn't think sewing machine motors were that big. I have a typical sewing machine and the motor is quite small.

Is it a used, out-of-print, book? If so, I would download it and not worry about it. While I prefer to have the physical book in hand, the prices for many used books has gotten insane. I've seen some books list for over $1000USD.
