  1. Hi Alan, Check the owners planning permission,  and the surrounding area's classification. Quote;     A B1 use must be capable of being undertaken "in any residential area without detriment to the amenity of that area by reason of noise, vibration, smell, fumes, smoke, soot, ash, dust or grit". If that is the case you are going to have long term problems, A lot of the new industrial estates also do not accept byproducts from blacksmithing. Sometimes you even have problems convincing planners it is a rural traditional craft. It is not an easy path but there are ways whereby you can find somewhere to work from. A private chat may be of use.   
  2. Personally I have yet to make a long term assesment of it. My usage may differ from yours, but all reports I have heard from others using it seem to be quite favourable and somewhat cheaper than the coke. We have got the Devon County Show coming up this week on Thursday, Friday and Saturday, so should have something to base an opinion on. If anyone is around, come along and introduce yourself, we usually have a kettle on and a cuppa on offer, Also an excellent static display of competition pieces, and live forging demos and competitions, this year the competitors have two hours to forge a kinetic sculpture, 30 minutes to make something sellable, and 45 minutesto forge an axe head from an old farrier's rasp.  
  3. Anyone ever made a Valet Hook?

    Yes, angled to suit for hangers to facilitate easy removal and air circulation when clothes hung on them. 
  4. Anyone ever made a Valet Hook?

    What springs to mind to hold hangers is similar to the traditional trammel hooks with ratchet like teeth on, instead of the punched hole type, (which would make manouvering your clothes hangers into position somewhat difficult)

    Hi Andy, probably a bit of both, draft angles make for easier removal of patterns in the sand casting process used in making tuyeres, and the taper reduces the possibility of an air lock when the tuyere is being initially installed and filled with water,  Some of the water cooled cast iron tuyeres had no bosh tank directly attached to them, but a reservoir tank was connected by pipes to them. This reservoir tank could also be used to provide hot water for other uses in the area.

    There is no necessity for the tue to be conical in shape, just tilt it forward at a slight angle so any air does not get trapped at the front when you are using it,

    Not argumentative at all, it's called research. It seems there is a lot of "I have heard" and "In theory" around, all I can say is that as you can see, that design works. A few more things that may help, Chimney size works better above 10" diameter, The gentler the slope on the hood the better and make sure your line of sight to the fire when standing by is unblocked by the hood,  The side screen is normally used if there is a substantial amount of wind present, if it is a relatively gentle breeze, it is not needed,

    It is rising heat that causes chimneys to draw, not the smoke. One way to start any chimney to draw smoke away is to light a ball of newspaper or some small kindling and pre warm the chimney as you start to light your fire. Hot air rises and this helps to get the smoke (heavy air) to rise. The smoke will ignite when it is hot enough to, and will clear, whilst you work. Once your fire is going there should be no smoke from it, its new fuel that smokes. The picture does not accurately depict what you perceive as a wind block, there is a side screen as well as the hearth back, in effect forming an L shape and you work it from the open side depending on which way the prevailing wind is,  May be site dependent depending where crowd is looking at you from. This side screen can be detachable so you can choose to use it or not, it is not unknown for one to be hinged from the canopy itself, 
  9. Scrolling inside frame?

    I used to know an old guy who had a couple of large scrolls ( a pattern) and a bit of string, he would use a piece of sheet steel and mark off the width of panel he wanted to make the scrolls fit to, then he would place one of the scrolls over the area and rotate it until a portion of the scroll fitted to what looked ok. then he would mark it out and form his scrolls to suit, measuring the required lengths for blanks with his bit of non stretch string. Scrolls in rose arches look fine when there are no plants up them, but when plants and foliage grow, not much is seen of the scrolls, And scrolls are more expensive to incorporate than straight bars, a point to take into consideration if price is a concern. Good luck with the project

    Your C design will work outside just fine, this one is at a show where the forge hearth has been brought in from a working forge, there is a very short chimney section which is in effect a register plate for a taller chimney when it goes back to the workshop.    You could take your water tank further up to incorporate the hood support to help stiffen the canopy, this would mean you could have a narrower bosh with the same capacity as a smaller and wider one, a drain tap should also be incorporated if you are going to be using it at various events.   ,

    Just a couple of details, you have failed to show where the front of your tuyere is, this forms the basis of your fire centre, so you can move your chimney forward or, move the tuyere and bosh back a relative amount which would then allow you to have a rectangular tank as opposed to the U shaped one. (I am somewhat concerned about convection currents and water circulation if you go with the U shape). Are you using hand cranked or electric motor for fan? If you use coal or charcoal and a hand fan, you will not have to dissipate so much heat as you would using coke which you have to keep a constant air flow through. You also include Super Sucker chimney, How high is this going to be? If you move the chimney forward over the fireball, then the heat will rise straight up , super suckers need height to draw efficiently, this may affect stability and pose mounting problems. Nice theory, and drawing, I hope this is useful and helpful, you have put a lot of time and thought into this project, and I don't want to put a downer on it. The time to alter plans is before putting them into production. Good luck and I look forward to seeing pictures of it finished and in action.
  12. Building a scroll jig?

    Suggest you have a look here, includes most you need to know about making scrolls and a scrolling jig.

    Most bandsaw blades I have been involved with were flash butt welded usually on the welder supplied with the machine, others I have done have been oxy acetylene, mig or tig welded, the weld should be ground off to the same thickness as the blade, and the area where the weld is should be annealed. No need to reharden and temper, blade must be flexible. 
  14. K Blasting at Galmpton for details, but be advised that the works location is not at the address or postcode registered on Yellow pages, but in the old quarry off Kiln Road, it is on the same site as Marina Developments, whose address is  Dartside Quay, Galmpton Creek, Brixham TQ5 0EH, If you google their details and go to the aerial picture, you can see the K Blast buildings as you enter the Quarry. This company sandblasted and hot zinc sprayed the panels that were made at the 2014 International Blacksmiths Festival that are now installed for all to see at Westpoint
