Re: S&H charges

McMaster ships with envelopes as well. When I order drill bits or taps, they almost always come in the small white shipping envelopes. Jim B I get small items from McMaster in bubble envelopes too, I guess it could have been that they ran out of bubble mailers at Mr Ron's warehouse. Shipping is som...

Re: PM 9X50 knee gib adjustment

I'm going to assume you mill's knee has tapered gibs, if so, there's no easy way of not going one way then the other since you have to back out the jam screw in order to use the other screw to adjust the gib. My PM 932 has tapered gibs and I have to get on and off a small step ladder to adjust the Z...

Re: how to use youtube?

they have bills to pay, Google made 9.4 Billions tax free profits last year. That is a little bit more than paying bills. A by product of not selling ad space to break even. :D But both Google and Youtube are really in the business of focused advertising. I think the bottom line is that Google and ...

Re: how to use youtube?

But both Google and Youtube are really in the business of focused advertising. I think the bottom line is that Google and Youtube aren't in the business of focused advertising, they have bills to pay, G & Y were once ad free, I Google was, but they still needed to pay for their access to the intern...

Re: how to use yooutube?

Youtube has it's own algorithms that determine what you like based on what you click to watch, and I think, not confirmed, but seems to be my experience , they will also use the cookies in your browser to target ads and content at you. So if you frequent political sites, the ads you'll see will be p...

Re: Winding springs

The only problem I see in using a threaded rod is that you wont be able to make the tight coiled lead in and out of the spring, it would depend on the wire gauge that you're using whether you need that lead in and out, grinding the ends flat would work on thicker gauge wire. I prefer using the threa...

Re: RF-45 oil seal replacement

Thanks Inspector, it's a informative link, even though he doesn't get to that oil seal, luckily his Flicker images are still up.It's interesting how my experience with a new, never run RF-45 clone is so similar in regards to the swarf inside the mill head, and a missing bearing cover, I suspect a go...

Do you have an idea who the member is, assuming he's a member of this forum ?
It would make searching for the thread easier.

RF-45 oil seal replacement

Any owners of dovetail column RF-45 mills ? I buggered up one of the two spindle shaft oil seals so I figured I would replace both but these shaft seals are normally pressed in from the flat face side, the seals in the mill are in a end cap so the flat face is facing down, I'm hesitant in removing t...

Optical contact bonding

Taking a break from work ( i.e. goofing off ) I came across a video about the science of flatness, not a very good one but in the segment about gauge blocks and molecular bonding it did mention something about optical contact bonding, decided to look into it further and came across this video from a...

Re: gunsmithing tools

There is quite a bit of gun related stuff on eBay , tools, mainly pin punches, holsters, and surprisingly Airsoft BB guns ! I don't pretend to know what tools are needed for gun smithing ( other than a lathe and mill ). Unless eBay has express rules against gunsmithing tools, I don't see why you sho...
