I suppose I've been indulging in some new vises. 

After years of relying on various clamps for work holding, I've added several vintage vises to the fleet, and belatedly realized how useful they are. I've been clamping stuff for cutting, filing etc. and sometimes really sketchy workholding setups resulted. As usual, lack of space in the little shop meant I had to skip the mega bench mounted Wilton I lusted for, but eBay provided some great finds.

For metalworking, after looking at every large bench vise out there and not wanting to sacrifice a corner of the welding table to it, I realized a woodworking vise was a great option. This Wilton corner vise is perfect and didn't take up any work surface.







Doubles as a drill vise for big stuff.



The old Will Burt is awesome for fine work, but I still wanted a traditional bench vise.



Eventually came across a 3" cutie that I can mount to a plate and move around as needed.



Mounting plate is a holiday week project. I'm thinking perhaps a 5/8" hole pattern on 2" centers to fit the welding table and some countersunk threaded inserts in another work surface so I can swap it around when I need the top clear for jigging up stuff to weld.

Being on a roll, I found a really nice Morgan that I plan to quick-mount to the 80/20 Sys Cart for woodworking. It's winging its way to me now.



About the only thing lacking is the big-iron-whack-it-with-a-3-pound-sledge vise, there's just no room for it.

Any thoughts/suggestions from your personal vises?

Those vises are robust!

As a woodworker, I have only a small metal vise for my primitive metal needs.

A few years ago before the pandemic, I fabricated (with $50 Cdn of supplies) and added a tail vise to the bench, which is useful for hand-tool woodworking.

The Wilton corner vise is a nice add to the welding bench.

Do you have a tree stump or large section of log you could mount the big vise on in a manner similar to an anvil?

If not, there is likely to be someone cutting a tree down not far from you.

Bob, I got one, from a neighbor's yard, several years back for that very purpose. It ended up being repurposed as a beverage stand...

Good eye.

Something similar to this $29.50CAD vise (which wasn't carried by LVT at that time): https://www.leevalley.com/en-ca/shop/tools/workshop/workbenches/vises/110469-toolmakers-vise?item=70G1115

Here’s my go to:



Red Seal 55 by American Scale Co. 5 inch jaws.

Got it at a yard sale.

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

I noticed that too, pretty slick idea.

OK on the stump. Makes a nice table.

The latest (& last?) member of the fleet arrived. It's a beauty, and oddly enough the second time I've owned this exact same model vise. The first one went to a new home (attached to a large maple bench) after we moved to the shore and I'd given up my large shop, I've always missed that vise.

The Morgan 200 is fast acting (partial turn to engage/disengage the screw), 10" wide with 12" capacity. When it came up on eBay $200 seemed like a deal from Oregon to my back yard.

Anyway, it needed an interface to mount to the 1530 extrusion, so Saturday involved some metalwork. Started with 1/4" cold roll, 3-3/4" wide. Forming taps are my 2021 find of the year, I didn't know they existed & I've always used thread cutting taps.













Sits nicely below the level of the top, shouldn't interfere with using a track saw.




 
Still need to remove & finish somehow & add jaw faces. In theory I can loosen the fasteners and slide it anywhere along the extrusion, but experience dictates it may never move again.

I think spring will be about time to put some lipstick on the shop, it's looking a mite beat up.

I guess the pilot hole for a thread forming tap is larger? How is that determined?

From what I remember about Guhring, they were less critical about the pilot hole size but I presume that was because they were just applying brute force to complete the job.

These newer taps seem to be more nuanced and they talk about the criticality of the actual HOLE diameter and not the drill diameter. They recommend several hole sizes based on the percentage of thread that's required. However, they go on to say that it's best to drill the hole and experiment with the drilled hole size.

One manufacturer referred to a hole diameter changing by .001" would increase/decrease the percentage of thread by 10%...that's a ton.

I'd like to learn more about this latest generation of thread forming taps, specifically if they are this sensitive to hole diameter because that could be a real challenge. No more hand sharpening of drill bits. 

@Cheese it took me forever to track down the forming taps, finally bought my most common sizes from a seller on Amazon, Suncoast Precision Tools. I kept seeing taps used on YT (The Metalist) but couldn't figure out what they were.

Yes, pilot is slightly larger than a thread cutting tap, L drill for the 5/16-18 I used. .033" larger than for a cutting tap in this case.

When the tap arrived they'd included a tap/drill chart with pilot hole specs for both.







Really happy with these YG taps, I'm probably going to invest in a set soon.

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?

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

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:
