Hi Is anybody from you who use the following iron bending heater: http://www.aliexpress.com/item/Bending- ... 74601.html There is quite cheaper (50%) of the one in UK. But I would like to ask about shape - is it OK? is different and quality of the stuff and of course effectiveness of the heat;) Please let us some your experience;) |

The shape looks good and that's a good deal. You never know with Chinese products till you try them. The only issue might be if you cook a heating element and need a new one. |

The heating element is cheap c.a. 5 quid - no problem to buy and replace. I have temperature's controller for Fox and I can connect the iron bending to it with themr connector and get control of the temperature  More important for me what is the material of the shape - probably aluminium - but the question is what is internally - full alluminium or space with heater like a big tube |

Big tube is fine. I made mine out of a piece of aluminium from an aircraft strut. It's hollow and works great. |

looks ok to me for the shape. No idea how well it heats or how evenly. It sounds like you're OK with tinkering with a heating element and controller so I'd just build one from scratch. A piece of car exhaust pipe works great with a heater inside (make sure its not still attached to the car) |

Heater cartridge you put a link to - I can give you one! Bought 2, burnt 1st one out first time I used it. Heat cartridges need to be fitted in a similar diameter hole in a solid block, usually aluminium for a bending iron. They need to have an efficient heat sink. I thought I might get away with filling the tube with SS scouring pads, but they didn't seem to provide enough of a heat sink so it burnt out. I did make one with a catering heating bulb like this http://www.ebay.co.uk/itm/CATERING-HALOGEN-HEAT-LAMP-BULB-500WATT-DOUBLE-JACKETED-GANTRY-LIGHT-118MM-R7-/231362300099?hash=item35de4488c3:g:dDoAAOxydyxSQMvs But find the heat with the BBQ lighter quicker and more even (and you need to get a holder for the bulb/heatproof wiring as well, bit fiddly. Maybe I can take some pics tomorrow, its a bit late today. |

Some pics. The tube itself is 325mm long, usable end the of bender about 180 mm. Endplate is pop riveted on as you can probably see. |

Did you think about aluminium foil put inside with heater? It will better lead the temperature on the tube. |

prezio wrote: Did you think about aluminium foil put inside with heater? It will better lead the temperature on the tube. Yes I did actually. But after my experience burning out the cartridge, I though it might be better to leave it as it is, (and most of the others like this I've seen) as it is normally used in a place where it has a fair bit of air circulating. It warms up fast and hot, and heats the business end quite evenly. |

Small question - the question is for people from UK May I ask you where can I find to buy steel sprint sheet/strip with length 100cm, width 15 -20cm and thicknes 0.3mm? (I need for fox bender) I try to find but I can't ;( I found in germany but - hmmm + delivery is quite expensive;( |

| Author: | prezio [ Wed Jan 13, 2016 8:36 am ] |
| Post subject: | Re: Iron Bending heater |
Of course it can be bigger size - I can cut it. (but thickness must be 0.3mm +-) |

| Post subject: | Re: Iron Bending heater |
Is £11 total cost too much? Heard of Ebay? Lots of stuff there, e.g. http://www.ebay.co.uk/itm/Stainless-Steel-Sheet-Foil-Spring-B-100mm-x-Thick-0-01-1mm-1-4310-/171967921128?var=470858277726&hash=item280a163be8:m:mKSXM7RVDo2k-NtM3B38JXQ Search "steel shim 0.3mm" |

yes very hard to find 100cm length with width 15cm or 20 - what you send me is only max 30cm length and 10 cm width. The strip with 10cm (100mm) width I can find on aliexpress - but not wider If yes I need to buy 300kg of it ;(

I still have the other 3 kicking about the workshop somewhere. What I bought was 150 mm X 915 mm, CS95 hardened and polished spring steel, 0.12"/0.3mm thick, http://springsteelstock.co.uk/ They were very helpful - Steve was the guy I dealt with, if he's still there.. |

Thx I"'ve sent question - now they have 152 mm x 1000mm x 0.3mm in their offer Will see when receive answer - thx In meantime I ask - do you have any good company with coloured veneers in UK - I fond quite good on http://www.thewoodveneerhub.co.uk/ and do you have any good company with tonewood about which you can tell me;) |
|
| Author: | Colin North [ Wed Jan 13, 2016 3:01 pm ] |
| Post subject: | Re: Iron Bending heater |
That's the same company I use normally for veneers. Tonewood suppliers. Lots. Googling "guitar tonewood uk" gets you https://www.google.co.uk/webhp?sourceid=chrome-instant&ion=1&espv=2&ie=UTF-8#q=guitar%20tonewood%20uk Quite a few, mostly good, although prices and quality vary. Best to visit yourself and inspect if it's practical. The bulk of my tops I've bought direct from abroad, several at a time usually. It's economic and I've always had good quality. What are you looking for - a starter set to build with? A kit? ? ? I would just mention that if you need to cut/drill that spring steel, it needs diamond cutters or special drills. |

How many bending slats do you need? Usually 2 for light bulb bender, 3 for blanket bender. I really don't have the time to list all the suppliers I've used and know off. but could give you a recommendation or 2 if you give me an idea what you want to buy. As it's a first guitar, perhaps you might be interested in this - UK supplier, kit for classical guitar, discount for a "bulk" buy, more or less all in one, upgrades available. Very reasonably priced. And as a first time builder, and not really knowing how many you intend building. I would suggest using a bending iron. It's always good to have one even if you go on to use a fox bender. http://www.luthiersupplies.co.uk/dcguitar_kits_4.htm Oh, and one question. Do you have humidity control?? If not, I would strongly suggest you do something about that, before starting. |

| Post subject: | Re: Iron Bending heater |
OK - I understand - I want 2 slats if I can 3 - now I have bulb bender but I plan to buy blanket but not now. I'm looking for the tonewood for classical guitar - at the begining all parts dedicated/prepared for guitars. Mostlu Spruce and mahogeny and ebony. but if you now somebody who sell quatersawn timer it can be usefull as well - I have tools/machinery on which I can cut. |
