andypugh Posted October 14, 2014 Share Posted October 14, 2014 A friend has just bought himself one of these: http://www.boltbusterinc.com And appears to be impressed. Probably of more use on newer stuff, actually, as I have never known an old Whitworth nut to not eventually unscrew, but the UNF threads on old Mini's seemed to permanently fuse the moment they left the factory.

Toner Posted October 14, 2014 Share Posted October 14, 2014 That looks like a handy bit of kit. Quote Link to comment Share on other sites More sharing options...
fv1609 Posted October 14, 2014 Share Posted October 14, 2014 That looks very impressive Andy. But I couldn't see anything about the basic power source. In one picture you can just see a cable folded down out of view. The video doesn't show us that end of the gadget, to presumably enhance the magic effect, but you can see power distribution panel to the left of the work bench with a cable coming from it. I don't see why they are so secretive about not mentioning the power source. But being but for the US market I assume it must be 115v. Andy is your friend in the UK, how did he manage the power source? Quote Link to comment Share on other sites More sharing options...
andypugh Posted October 14, 2014 Author Share Posted October 14, 2014 My friend is in Colchester, which interestingly is where the UK distributor seems to be. http://www.bolt-buster.co.uk/index.html#1 One picture shows a plug-in power supply. It is interesting how the US price of $369.99 (£232) becomes £395 on the UK web site, then £495 when added to the cart, then £594 when VAT is added.

David Herbert Posted October 14, 2014 Share Posted October 14, 2014 (edited) I would have thought that that would only need an ordinary mains input. The HF inverter will be in the handle piece. Quite apart from its intended purpose I would think that it would be great for heating smallish rivits, say up to 1/2" dia when hot riviting. If anyone finds a UK market equivilent I would certainly be interested. David Andy types a bit quicker than me! The £594 is certainly going to limit their market I think. This is a very simple device and really ought to retail at about £200 ! Edited October 14, 2014 by David Herbert Quote Link to comment Share on other sites More sharing options...
John Comber Posted October 14, 2014 Share Posted October 14, 2014 You can purchase these in the Uk, look on ebay they come under an induction heater, both Sykes and Snap-On make good quality ones. We have a pal locally who purchased one , I am forever borrowing it now ,a marvellous piece of kit, and much safer than the old gas torch!!

RattlesnakeBob Posted October 14, 2014 Share Posted October 14, 2014 here's the same thing a lot cheaper ??? http://www.ebay.co.uk/itm/Bolt-Buster-Magnetic-Induction-Heater-Tool-Coil-Kit-Included-110-VOLT-BB2-/161430440206?pt=Motors_Automotive_Tools&hash=item259601090e Quote Link to comment Share on other sites More sharing options...

Tony B Posted October 14, 2014 Share Posted October 14, 2014 110 volts though Easy enough to get a heavy duty 110 transformer. A lot at boot sales for 15 -20 quid recently. Has the added advantage , often a load of cheap 110 v power tools and portable lights with them. Quote Link to comment Share on other sites More sharing options...
fv1609 Posted October 14, 2014 Share Posted October 14, 2014 A rather lower power one (200 watts?) for £39.99 http://www.rmcybernetics.com/shop/cyber-circuits/pulse-generators/induction-heater-circuit http://www.rmcybernetics.com/projects/DIY_Devices/diy-induction-heater.htm Quote Link to comment Share on other sites More sharing options...
Tony B Posted October 14, 2014 Share Posted October 14, 2014 Humm. I'm begining to wonder, could you end up welding the nut on rather than taking it off? Quote Link to comment Share on other sites More sharing options...
Charlie Posted October 14, 2014 Share Posted October 14, 2014 Or just melt it? http://www.ebay.co.uk/itm/25KW-30-80-KHz-High-Frequency-Induction-Heater-Furnace-LH-25A-/231032390071?pt=LH_DefaultDomain_3&hash=item35ca9a81b7#ht_2378wt_1053 Quote Link to comment Share on other sites More sharing options...
Sean N Posted October 14, 2014 Share Posted October 14, 2014 ...a marvellous piece of kit, and much safer than the old gas torch!! You'd buy a lot of gas for the hot spanner for £600 though John!! Quote Link to comment Share on other sites More sharing options...

Tony B Posted October 14, 2014 Share Posted October 14, 2014 Would the smallest coil fit a coffee mug?:cool2: Proably vapourise it! :shocked: I knew an old electrician used to claim he made his tea by knocking two nails through a bit of wood wiring it to the mains and dropping it into the cup. Never had the nerve to ask for a demo though. Quote Link to comment Share on other sites More sharing options...

LOL your quite right there Sean, what we like is you only heat the item with the inductor against which when near 100 psi tyres is more comforting than warning the rim as well.

Charawacky Posted October 16, 2014 Share Posted October 16, 2014 Sounds like an interesting, versatile tool. I have an old Radyne bought for £250 a decade ago, which is used to selectively induction heat, hardened drive chain pins of about 1" diameter. This unit heats and softens the ends of the pins, to allow the ends to be riveted during assembly without loosing the previously hardened load bearing portion in between. It looks like they have now condensed the electrics considerably, our machine has an electrical cabinet of about 2 meter cube fitted with a water cooled triode valve. This thread has got me thinking about using it for re-riveting an old chassis! Tom Quote Link to comment Share on other sites More sharing options...
flandersflyer Posted October 17, 2014 Share Posted October 17, 2014 you can use a stick welder to unfreeze stubborn bearings.... should work the same for tricky bolts, nuts etc.... Quote Link to comment Share on other sites More sharing options...
andypugh Posted October 24, 2014 Author Share Posted October 24, 2014 This thread has got me thinking about using it for re-riveting an old chassis! It could work very nicely with my rivet squeezer: http://bodgesoc.blogspot.co.uk/2014/04/hydraulicrivetsqueezer.html In theory you could probably re-rivet the existing heads. (wouldn't re-swell the body though) Quote Link to comment Share on other sites More sharing options...
