Crucible Holdfast FAQ

Posted on by Lost Art Press

hole_enlarger_use_img_6269

During the last 20 years, most woodworkers have adopted 3/4″ as the standard size for holdfasts, bench dogs and other workbench accessories. So why the heck are we making holdfasts at Crucible Tool that have a 1″ shaft?

Simply put: The larger holdfast has more mass, it doesn’t ream out your bench’s holes as fast and we think it just works better.

During the last couple weeks, I’ve written a series of blog entries on the Crucible Tool website that explain our reasoning. Despite this, we continue to get a lot of questions, and so I’ve consolidated all the answers here.

(Side note: We are working on offering a way for you to subscribe to the Crucible Tool blog so you can get updates via email. In the meantime, if you use an RSS reader, you can subscribe to it via this feedburner link: http://feeds.feedburner.com/Crucibletool-CrucibleNews.)

Q: Why did you choose 1″ instead of 3/4″?

A: We do have a good answer. Really. It’s here.

Q: OK, so if I do switch over to 1”, how do I enlarge the 3/4″ holes on my bench?

A: There are many ways to do it. Here is a quick and inexpensive way.

Q: Hmmm. So I use my dog holes for holdfasts sometimes. So I would need to switch to 1″ dogs. That sounds expensive.

A: It’s really not. Here’s how to make an entire set of 1″ dogs for about $11. Wooden dogs are gentler on your tools.

Q: I’m building a new workbench, where should I locate my holdfast holes?

A: We have a map of what we prefer here.

Q: So why does your holdfast fit so tightly in the hole? Other brands just drop in?

A: There is a very good reason for that. Here’s why. And here’s some more.

Q: How do you make your holdfasts? And where?

A: They are ductile iron and made at the Erhart Foundry. You can read all about it here.

Crucible Tool is Now Open for Business

Posted on by Lost Art Press

You can now visit crucibletool.com, and read up on our holdfasts, our new dividers and why we started this company. I’ll be adding a lot more blog entries in the coming week, including:

  1. How to retrofit a benchtop to use 1”-diameter holdfast holes.
  2. How to carefully ream holdfast holes for a sweet fit with the tool’s shaft.
  3. A tour of Chris Erhart Foundry, where our holdfasts are poured.
  4. An update on the next batch of dividers.

Note that we are not taking backorders for the dividers. To prevent us from getting into a bad situation that plagues many young businesses, we have decided to sell only what we have in stock. No backorders. No waiting lists.

When we have stock, we will announce in advance when the dividers will go up on the site so everyone has a fair shot. And we think we’ll soon have enough to keep them in continuous stock.

We have plenty of holdfasts and T-shirts in stock.

Crucible Tool Update & Dividers

Posted on by Lost Art Press

Teaching and exhibiting at Woodworking in America – and launching a tool company – proved to be an around-the-clock yack-fest. As a result, we are just now putting the finishing touches on the Crucible Tool website and will almost certainly launch it this week.

The other news is that we announced our second tool: 6” dividers that are being made on our Haas CNC mill in Raney Nelson’s Indiana shop. We had a handful of dividers to sell at the opening event and sold out of them. Raney is cranking up production shortly so that we have stock on them in the next few weeks.

Thanks to the foundry, we have a fair number of holdfasts to sell on the site when it launches (priced at $130, which includes domestic shipping), plus T-shirts ($25, including domestic shipping).

We’ll have lots more details about the dividers on the Crucible site, but the short version is this:

They are based on early 20th-century blacksmith-made dividers and can be adjusted precisely with one hand. But instead of securing the divider’s hinge with a peened pin, we have designed a mechanism that can be adjusted with a No. 10 spanner drive bit (included) so you can adjust the hinge’s friction when it becomes loose through normal use.

The dividers are made using O1 steel and are machined and hand-finished in our Indiana workshop. The price is $120, which includes domestic shipping.

Woodworking in America, Crucible Tool & Lost Art Press

Posted on by Lost Art Press

Next week, Woodworking in America will command all our attention. We’ll be selling books and tools in the Marketplace, Raney Nelson and I will be teaching classes upstairs for registrants and we will officially launch Crucible Tool. Here are some details.

Crucible Tool
We’re holding a launch party on Thursday night at our Covington storefront. We are booked up, so if you don’t have a ticket, please visit us in the Marketplace on Friday and Saturday where we will have tools for you to check out. During the launch event, we will demonstrate (and sell) our holdfasts and the second tool in our line.

I’ll be honest, we have been working like crazy to build up inventory, but I’m not sure how many units of our tools we will have on hand. Getting our production levels cranked up has been a challenge.

Lost Art Press
Lost Art Press and Crucible Tool will share a booth at the Marketplace for Woodworking in America. We’ll be selling our full line of books and tools – plus special T-shirts and posters. You’ll be able to try the tools out, check out all our books and even try out the two Roman workbenches I’ve built this summer.

However, we won’t have our storefront on Willard Street open during Woodworking in America. Our companies are – in essence – three guys. And we will both be working hard at Woodworking in America with no time to keep the storefront open. Sorry. I wish we had a way to make everyone happy here.

Classes at Woodworking in America
I’ll be teaching three classes at Woodworking in America and moderating a roundtable discussion amongst the leading planemakers of the day. Raney Nelson, who is one of the three principals at Crucible, will also be teaching classes. Check out his classes here. Here are the official descriptions of my classes:

Nails & the Decline of Western Civilization
Class Times: Friday, 8:30 a.m. – 10:30 a.m.
In the early 19th century, nails represented one-half of one percent of the country’s GNP. That percentage is equivalent to everything that everyone in the country today spends on computers and personal technology in a year (a lot). This country was built with nails. But about 1860, something horrible happened: Nails became terrible, and furniture makers rightly turned their backs on this once-critical fastener. What happened? And what can we do to restore the nail to its rightful place in the shop and as a historical hero? It’s easier than you think. Come learn everything you need to know about nails.

The Roman Workbench – How does it Work?
Class Times: Sunday, 8:30 a.m. – 10:30 a.m.
The Romans (or perhaps the Greeks) invented the woodworking bench, and this robust and simple design lasted more than 1,500 years. Then the form disappeared. Christopher Schwarz has spent years studying benches, and he’s built two of the most famous Roman-style workbenches: one from 79 AD that was shown at Herculaneum, and another from 1505 that was both the last Roman bench and the first modern one – a fascinating example. During this session, Chris takes you on a tour of how these two benches work and shares his thoughts on why they have survived in isolated pockets of civilization, such as Estonia and rural Maine. Participants will even get the opportunity to try the benches for themselves.

Build a Chair without Chairmaking Tools
Class Times: Sunday, 11:00 p.m. – 1:00 p.m.
Many woodworkers are put off by chairmaking because you typically need a lot of specialty tools, green wood and skills that are outside of the typical garage workshop. For the last 12 years, Christopher Schwarz has been developing a number of techniques and joints that allow the typical entertainment-center-building woodworker to make a traditional chair without investing in a lot of new tools, having to take a week-long class or having to chop down a tree. If you own a jack plane, a brace and a spokeshave you are almost there. Come see.

Planemaker’ Roundtable
Class Times: Saturday, 1:30 p.m. – 3:30 p.m.
The plane is one of the fundamental tools of woodworking – even if you use machines, you likely pull out a block plane from time to time. In this roundtable discussion, Christopher Schwarz moderates a discussion of handplanes in the modern shop. With Konrad Sauer, Raney Nelson, Caleb James, Terry Saunders of Lee Valley, Thomas Lie-Nielsen of Lie-Nielsen and more.

Somehow all of this will happen, and it will be as mind-blowingly awesome as it always has been for the last eight years. So if you are in Covington next week, please stop by the booth and say hello.
