Coming to grips with my vises...

So Richard you just drill the hole, place the tap in a holder and chuck it into the impact wrench?

Any issues with breaking taps?

That Morgan's nice Richard...reminds me of the early Record 53 although the 2 tie rods look larger on the Morgan.

The last time I checked (about 4-5 years ago) on thread forming taps, the only items available were from Guhring and they cost around $50-$75 each. They needed a ton of force, a ton of speed and a ton of lubricant, not easily performed operations in a small home shop.

This new version appears to be formed using just a hand operated impact gun? Is that correct?

Who makes the taps and please share your thoughts on the process. I assume you thread formed the cold rolled?

[member=44099]Cheese[/member] mostly answered in the prior posts but yes, power tapped using the impact driver on #2 speed setting with a couple drops of Tap Magic and I've had zero issues. YG taps, I suspect they are best used under power, probably not suitable for hand tapping.

Yup & nope. I'll try to grab video next time, only issue is taking my finger off the trigger fast enough, I normally run past the threads before I get it stopped. 100% recommended.

What kind of holder secures a square ended tap?

I would assume you use a standard jacob's chuck around the round part of the shank.

I've used these with regular cutting taps.  There's some wiggle in the square end, but it never seemed to hurt anything.

Lisle Tap Sockets. Basically the same as the Irwin.

I hadn't done much research on form/roll tapping but all the questions got me curious. MSC has a page with a ton of good  info:

I also use the Lisle sockets for conventional taps...the issue is drills have soft shafts and so they chuck up tightly (deform) in the drill chuck, taps have hardened shafts and if you try to chuck them up they simply spin in the chuck. Your only alternative to drive hardened cylindrical shafts is to use diamond imbedded chucks...ya that's expensive.  [smile]

This is the same problem when you chuck up end mills in drill presses. That's where collets come in.

The Lisle tap holder sockets are the same as the Snap-on version, just priced at a 50% discount.  [big grin]  Lisle manufactures these for Snap-on.

This positive socket drive stuff always makes me nervous because I've had my share of hardened taps being broken off in various materials...and that is always a huge PITA.

Hey Ron, thanks for the heads-up, I ran across that today after I read Richard's post.

I decided to investigate this new thread forming technology today on the MSC website.

When I first looked at it about 4-5 years ago MSC said there were about 100 thread forming taps available to purchase.

Today they said there were over 8000 taps available...how the world turns in just 4-5 years.

Dang! I just realized that you flipped a vise over to get the tail vise, brilliant. Thanks for sharing.

The toolmaker's vise is now back in stock!https://www.leevalley.com/en-ca/sho...hes/vises/110469-toolmakers-vise?item=70G1115

At $29.50 Cdn, it's pretty much the cheapest in the market, based on my previous research. I missed it last time, and I'm getting one now.

That’s a really handy item Chuck…I keep a Palmgren version on the drill press table permanently. Just used it yesterday for drilling small aluminum parts. Dinner winner.  [smile]

For anyone looking for a really nice quick action drill vice there's a 3" Heinrich on eBay ending tonight. Bid is $75 now.

I'd be bidding myself but a similar Yuasa is heading towards me now.

The 6" Grizzly G5761 like I have is on sale right now for $138.37...not including shipping.  I also have their smaller 4" one G5760 that I use on my small bench drill press.

 

[rmwarren]

Very happy with the latest addition to the fleet. I was waffling on buying a 3" but it's as much vise as the little drill press can handle.

Turns out it's made (or simply sold?) by Yuasa, label has just fallen off. The finish is original & it grips like a pit bull. Should have taken the quick action plunge sooner.

FWIW, the Homecraft DP is a late 50's sibling of Walker Turner which Rockwell acquired. Found it on CL years ago for $100 & it still had the cardboard sleeve on the post. Great little machine.

Again, couldn't resist.

I've been hunting for a nice low profile Versa Vise to complement the older, tall vise. So many junk ones (mostly damaged jaws) hit eBay with inflated prices I was beginning to think I was outa luck. Someone else did the restoration on this one then decided they liked their tall one better and listed this.

Nice Richard......really nice. That's the last model that Will-Burt manufactured before Gaydash took over the production and tried their hand at cost cutting.  [sad]

I really like the finish on it, is that painted? It almost looks like a hammer tone finish.

[member=44099]Cheese[/member] seller said it was Hammerite Hammered Bronze. I'm not familiar with the product but it is really nice. He also found a replica sticker, overall I think I scored with this one.

Sadly, I think I've accepted that I'll never end up with a use for the large Morgan 200 I posted earlier. Removing the big rolling MFT cart was the best change I've made to the shop but it leaves me with no place for it. I'll probably offer it here soon, it's a really nice specimen.
