Hi all,

Finding metal holddowns here (NZ) is far from being trivial. the word that springs to mind is “impossible”. I was thinking that nothing much prevents me from making some from wood but was wondering if someone already tried doing this. internet search didn’t find anything.

Is the main issue shipping to NZ? I’m assuming your wanting to secure something to the top of a bench. I just picked up a pair of these from Tools for working wood…. Plan to use them in saw benches…

But, it would help if you described what your trying to hold down. Lots of stuff can be done with wedges and dog holes….

Another thing would be to check for local blacksmiths and see if they could make some.

yes, exactly like these. Blacksmiths are also a very rare animal here. I just thought that if there is a way of making them from timber, it would be both elegant and simple and cheap for me. shipping this kind of stuff here is prohibitively expensive as they are pretty heavy. I generally know all the tricks with wedges etc, but thought it would be nice to have these as well as they are very quick to use.

I’m not sure I’ve ever seen any made of wood before. I ran a quick google search and came up with this one

made these long time ago, however they are not the same. slower to set and takes more space on the bench. I would think that bent wood or even laminated bent wood would work great for this but as there is no footprint of this ever being done, i was trying to find out why…

what about this type Stefang made :-)
http://lumberjocks.com/projects/16919

or like this clap just with a wood instead of the metal bar
and with the movingpart upsidedown in the top
http://lumberjocks.com/projects/25857

there is others on LJ that had made them in wood only

take care
Dennis

The Stefang ones are on my todo list but they are not really suitable for this. the wood/metal combination should work. one of the options I considered was using a shaft with piece of timber pinned on top. not as pretty as bent wood but would probably work well :-)

I lI like the homemade ones from Dan’s Woodshop, but what popped in my head, is why couldn’t you use a carriage bolt with a piece of scrap hardwood? The Popular Woodworking article claims 83 degrees is the perfect angle, so drill a tight hole through one end of the scrap at that angle, shape that end a bit thinner than the other end, mallet the both through your scrap and voila.

I think you could have most any welding shop make a pair for you. They would not be very difficult to make.

I would be worried a wooden model would break….

Another idea would be to go to the metal scrapyard and just find some 3/4” steel bar(again) ( remember we pulled some out of the tip in Murchison? but you forgot to take your piece with you) and bend it into this kind of shape. Or really leave it in the fire for a spell and bend it while hot and become your own blacksmith.

I can probably get steel bars but unlike this bar (which was mild) the ones I can get are hard steel…
I never did this kind of stuff and would probably need someone to look over my shoulder…

I wouldn’t think 3/4” bend beech will break that easily. again, just wondering. I will do some tests and let you all know.
as I have 3/4” beech dowel I made some time ago, i will probably just glue and pin a piece on top and give it a try.

again, the main point was that it was never done. woodworkers make such weird things from wood to get along (threaded rods, for example) but no one made these

There are a few decent blacksmiths up our way. I was meaning to get some made. If we find someone who can make nicely working holdfast, maybe we should get a few each. We’d all need to agree on the side of the holes though.

Metal and woodworking go hand in hand, so I suppose it was natural to use metal for some things and not wood for everything.
No suggestions in any of your books from Sir Roy Underhill? I guess there was always the shaving horse but I guess it depends why you want things clamped down.

Craig’s suggestion is a good one.

August – I know, I have seen that clamp idea at least once a week, but now trying to find that photo took forever.
