Re: How Risky are Old Surface Grinders?
I've never noticed the dust spreading very far with my dry DoAll 6x12, but it certainly gets in the nose. If you can find one with coolant and power feed, you'll like it a lot better!

Re: $1.99 Arc and Circle Cutter
I like it! Always great to make stuff using the scrap pile, particularly when it does such a nice job.

Re: Surface grinding machine
I'd suggest getting one with hydraulic feed if you can. Cranking the handle back and forth on a manual gets old pretty quick. And set up for coolant - makes a better job and keeps the dust way down. I have a manual dry machine and a hydraulic machine with flood coolant. Really don't use either very ...

Re: DC conversion on lathe.
You may as well use the controller that came with the treadmill. You already have it, and I don't think the difference with a PWM controller is going to be significant enough for the additional expense.

Re: Bidding advice on E-Bay???
I bid in the last 3 to 5 seconds - short enough to not let someone change their mind and add a higher bid. Won't beat a sniping program and of course a higher previous bid still wins. If you really gotta have the item, bid accordingly.

Re: VFD help.
Wally, There are lots of choices for VFD's that will power a 2hp motor off single phase. You will not loose any power when the motor is run at it's nameplated speed, but as it's speed is reduced, HP will also be reduced. Torque stays the same, more or less. I'm running several VFD's, not one of my m...

Re: Using Mill Vise
DWT2, The typical technique used for a non pull down type vise is to use a lead or brass hammer to give the part a whack downwards after getting the vise fairly snug. This lets the part slide down in relation to the jaw. If the part is on parallels, you can feel the part lift when tightening and aft...

Re: Shop made spur gear cutters
Rich, Gotta say that your method of generating relief has got to be the easiest and most practical way I've heard of! I made a backing off device from one of the gear cutting books - it does work nicely. Had I heard of your method, I'm pretty sure I wouldn't have bothered. Really worthy of it's own ...

Re: End Mill Storage
I store a couple hundred endmills vertically in pieces of foot long 2x10 with a grid of holes of common shank sizes. Doesn't take long to make and keeps them handier than in the packages. I don't have a photo, but I think you can get the idea. Also store reamers the same way, but use a 4x4 with the ...

Re: Anvil Tips
For general use, that 93lb Peter Wright should be a good anvil. Probably want heavier if you were going to do a lot of smithing, but if not, they certainly made good anvils.

Re: Newbie from Norway
Hi and welcome! I have a Beaver vertical mill, which is just a bit larger than a B'port. It has a 40 taper spindle in which I used to just use a collet chuck most of the time. This allowed the tool changing to be done at chest hight instead of up top. It worked, but still wasn't all that convenient....

Re: chip size via tensile strength
I have a hand powered shaper. Can't say as I've measured a chip off it, but it can be used to remove reasonable amount of metal, when set up properly. I would hazard a guess at up to 20 thou square chip, but it's been a few years since I've used it. It has a crude automatic feed system that uses a p...
