TomN Posted March 5, 2012 Posted March 5, 2012 I need to make myself a bar for twisting material. I need to go over the process, before I start it, to make sure I get it right. I thought i'd write down on here what I was going to do and people can correct me where I go wrong! Firstly I was going to take a piece of spring steel and cut off approximately 60cm of material to give me a 20cm 'handle' on each side and 20cm (+ spreading) in the middle to make my holes for inserting the bars in to twist. I would cut this length off, then make sure all of the toxic paint is burnt off, in a well ventialted area (outside for me). Straighten the bar out to give me a nice ~60cm long piece. Then I would flatten the central area, which would spread it slightly. This flat area, I can cut into to make different sized holes for twisting different sized stocks. I plan on normalising, or even annealing the central part of the bar to make it really soft. Then using the angle grinder with a cutting disc to cut in my holes to insert my different bits of stock into. Once I have all the shapes cut into it, I would make sure its flat and then harden the whole piece. So how far off am I with this, and how many beginners errors have I made? Quote
CurlyGeorge Posted March 5, 2012 Posted March 5, 2012 Tom, to make it simpler, just find an old monkey wrench and weld a length of 3/8" round bar on the top, opposite the handle. That gives you leverage plus the ability to be adjustable for lots of different sizes. I have two of these. One for my shop and one for my "traveling tool box" for demos. They work GREAT!! :) Quote
TomN Posted March 5, 2012 Author Posted March 5, 2012 I've been trying to find a monkey wrench for cheap, as that was the idel, but i've not been able to get hold of one! Quote
CurlyGeorge Posted March 5, 2012 Posted March 5, 2012 I have a second hand store here in town and he usually has a couple of them. Here's a picture of one of my regular ones and (I forgot about this one) a "super sized one that I used to twist 1" square stock with. If you would like for me to, I can pick one up and send it to you. Give me a PM with your address. :) Just realized that you are in the UK. Shipping may not be "cheap". :( Quote
TomN Posted March 5, 2012 Author Posted March 5, 2012 Those look ideal. Exactly what I wanted to make! Thanks very much for the offer, I appreciate it. I've found monkey wrenches over here, but they aren't that cheap. Plus they all come with hardened and tempered teeth, so they will be a bugger to grind down, to stop them marking my work. I will keep an eye out at car boot sales to see if I can find any. Might make the little twisting bar out of tool stool, whilst I wait. Quote
John B Posted March 5, 2012 Posted March 5, 2012 Hi Tom, Cannot post pics for some reason, must be new update like last time, look on Blacksmiths Tools Explained in the other half of this tool section and scroll down to Twisting tools another alternative you can easily make is there, Problem with holes in bars and tap wrenches is acccessing the section of bar to be twisted, as it has to be moved down from the end of the bar, not always convenient, practical or possible the open side is a far better solution, You could also use two pairs of tongs until you get what you want.

Backwoods Blacksmith Posted March 5, 2012 Posted March 5, 2012 10 or 12 inch adjustable open end with handle welded on the end. Adjustr real easy and are cheep to get. No teeth to grind. Quote
Pat Roy Posted March 5, 2012 Posted March 5, 2012 I just use an adjustable wrench without the added handle; haven't had any great difficulty with this. Quote
ianinsa Posted March 6, 2012 Posted March 6, 2012 That monkey wrench that you guys use is seen as antique shop goods outside of the USA and quite expensive I bought one for $50 and would not use it the way you guys do, "our" monkey wrenches have teeth for gripping pipe and they mar your work. Tom, it is not that difficult to modify a standard shifting spanner and add an extra "leg" thus achieving a similar tool!== having used those"american" twisters I must say they work really well.

Eric Sprado Eric, I want to come again this year, this time drag(I'm sure she's keen) my wife along I've raved on about the wonderfull folk/characters I met last trip and to show her where I think we should relocate to. I saw monkey wrenches galore in pawn shops and at yard sales and I was green with envy............. It would be wonderfull to sit round a fire listening to you, not just stories but your tunes!Best Regards my friend.Ian Quote
Randy Posted March 6, 2012 Posted March 6, 2012 Yea, you don't want the bar with holes in it. The monkey wrench is great, but for up to 5/8" square it's not needed. Just use plain hot rolled mild steel, 5/8" square is big enough and round each end for handles. Bend the piece in the center to match the size stock you want to twist in each side. So the drawing shows 3/8" sq. on one side and 1/2" sq. on the other. Two wrenches like this and you have twisting bars for 3/8" to 3/4". This was the way Francis Whitaker taught us. The second photo shows how they hang at the vise. With this style you can reach any where along the piece to twist. Quote
ianinsa Posted March 6, 2012 Posted March 6, 2012 Looks interesting! Hofi has a mean twisting tool! bit of effort to make but as with most(I havent tried all) things Hofi= it works. Quote
GNJC Posted March 8, 2012 Posted March 8, 2012 Tom, trawl through the boot sales once they start which, conveniently, is after the rugger season closes. You'll often get a good sized wrench in good condition for well under £10, often under £5. G. Quote
TomN Posted March 8, 2012 Author Posted March 8, 2012 I've been roped into clearing out my Grandmothers garage on Saturday. No doubt she will just want to throw stuff away, so I will be doing a check for tools whilst i'm there. Fingers crossed that I find something useful, especially if its a monkey wrench! I will be up the forge ALL of Sunday working away and trying stuff out. Quote
Pault17 Posted November 11, 2012 Posted November 11, 2012 found a pic of my stwisting wrench and thought I would resurrect this old thread Quote
