Production Begins on the Lump Hammer

Posted on 20 June 2018

Today Raney showed me the final pre-production version of the new Crucible lump hammer and – as of this evening – we are officially in production with this long-awaited tool.

Before I tell you more about the lump hammer, let me first explain why things have been so quiet on this blog. For nine months in 2017 and 2018, my sisters and I took care of our father as he ended a long battle with cancer (the cancer won).

This is not to ask for pity or to offer an excuse. It is a simple statement that working on Crucible during that period was simply too much. And so Raney and John have been doing just about everything to keep the company going, except for the blogging. That’s my job, and I’ve been MIA.

I can’t thank John and Raney enough for covering for me during this difficult time. But I am now ready to pull my weight for the company.

So About the Lump Hammer

We don’t have a date as to when the first batch will be complete and ready for sale. We are hoping for August. The price will definitely be less than $100 – we’re shooting for $85 or a little more. And that price will include domestic shipping.

The rest of the specs are the same. The head is hardened steel, weighs about 2-1/2 lbs. and is made in our laboratory in Indiana. The handles are hickory, American-made and charred in Indiana before assembly.


What Do You Use a Lump Hammer For?
Everything. Though I’ve been absent from Crucible, I have been using our lump hammers every day in the shop. I assemble and disassemble furniture with it. I mortise with it. I set holdfasts. Adjust planing stops. Anything that needs a heavy but controlled blow.

In the coming weeks, I’ll post a video showing some of the many uses for this tool.


So it won’t be long. The handles are made. The heads are in the mill. And the torch is getting warmed up.

    Chris my condolences to you and your family on your Dad’s death. To your Dad, from one Vet to another; RIP Brother.

    Chris,
    Glad you focus on family. Family is more important than anything we do or possess. May your hammer sales treat both LAP and Crucible Tool very well.

  • Hasin: June 26, 2018

    Sorry for the loss of your father Chris. Re: the hammers, will you be shipping to Canada?

  • James Watriss: June 22, 2018

    Rock on, very excited about the hammer.

    Salko, mortising with a big hammer is an easy thing, but it’s different.

    In short, to apply the same amount of force as you’d get from a regular swing with a regular mallet, swing less, and more slowly. Basic physics: Force = Mass * Acceleration. For the same force, with a heavier mass, you need less acceleration. So it’s more of a shove than a hit. But the slower action allows for more control.

    Salko Safic – I use a lump hammer for mortising all the time and it is so easy to control it’s insane. Give it a try, you’ll be surprised.

  • Dean Coss: June 21, 2018

    How soon will you be taking orders for them?

  • Adam: June 21, 2018

    Hello, will the hammers be available to your overseas fans (Australia)

  • Mike: June 21, 2018

    Chris, (and Family), you keep doing you. Nothing missed, during the silence. You were busy and that is what you needed to be doing. I’ve read a lot of your posts including the ones you shared with us out here what you were up to. As for the new tool,.. only thing that comes to mind. “KER-THUNK”

  • Nick Rosas: June 21, 2018

    So sorry to hear about your Dad.

  • John Thomas: June 21, 2018

    If the hammer is less than a hundred save one for me.

  • Ryan : June 21, 2018

    Thank you for the update and for sharing the reason for the timeline. We’re all just human Chris, hammers can wait: family can’t. Thanks again.

  • Salko Safic: June 21, 2018

    I’m not entirely sure how you could use this hammer for mortising etc other than in setting of hold fasts. It’s just simply too weighty which would tire you out quickly, plus how could you control your blow.
