the iron dwarf

not contacted them yet, some places are not happy to help when you got a few thousand $ worth of their kit from a scrapyard or they want you to only have it fixed at their authorised dealers for a lot of money an induction heater I bought for 10 uk pounds, the makers want me to pay them over 500 uk pounds so they can inspect it and test it before they supply me with a spare part costing a few pounds

I know it is not metric, looks very similar to m5 but is just a little smaller and about the same pitch, the screws are a bit short to count the tpi on I think the item was made about 2008 casing damaged so had to remove it to bash out dents http://int.haascnc.com/we_spec1.asp?intLanguageCode=1033&id=HRT310&sizeID=310MM_ROTARY

we dont often get problems with them here but an event I am trading at in july is in a bad area for ticks and last year several people were known to have contracted lyme disease there

have a 4th axis ( rotary table for a cnc mill ) and it has a few screws missing or damaged it is made in the US and is a HAAS HRT 310, it is recent and not an antique so can anyone tell me what threads are likely to be used the main one I need is about 3/16", measured at 0.186" or 4.7mm on the outside of the male thread and is quite fine. another thread of interest is the one for the lifting eye, measures about 7/16" and looks like our whitworth or UNC thread it weighs 438 pounds

visit when you can and we will have a chat, I have a few ideas

those metal sheds are paper thin and may even make things sound louder also they are very low roofed. foliage outside will dampen sound more the old fast growing leylandii would do well but need the tip cutting when tall enough or they get to be monsters and they are a bit flammable

weather here tomorrow humidity 63% temp 73F or 23C https://www.google.co.uk/search?client=firefox-b&ei=BaHsWtPOCIi9gAakq5nIBA&q=weather+kettering&oq=weather+kett&gs_l=psy-ab.1.0.0i131k1j0l9.12204.28310.0.30894.21.15.0.0.0.0.468.2228.0j2j4j0j2.8.0....0...1c.1.64.psy-ab..14.7.2032...0i67k1j0i22i30k1j0i22i10i30k1j0i131i67k1.0.Tpm0LpHhAAQ

you only need one shovel of sand nick enjoyed today but it was a bit warm

about 1960 IIRC when we both started using the same standard inch one of us had to add and one subtract a millionth of an inch to make them both the same. your survey inch is older and still in use

if on monday you do well you may be making a hot cut too Thomas did you know that about 50 years ago both US and UK inches changed? and that the US uses 2 different inches or that there used to be many different inches and feet from IIRC 11 inches to 17 inches to the foot, wales and england and germany had many systems and then you get to fingers, palms, shaftments and ells

how about a hot cut to fit your 3/4"?

yup, we can make a stand and maybe a hardy tool or two and metric or imperial is ok with me

ok, all I needed was 30.5 by 34 and you will want the height of it the size of your hardy holes is something to check so you know if tools will fit tap lightly all over the top to see if the sound changes, these may be areas of delamination, the area where the top has broken away is where you dont want to be using it or that can spread

and you have not met john yet. go measure your anvil and check for markings at the same time

may be able to make an anvil stand on monday as you are heading back this way, depends on having the right metal here and you knowing the height and base of your anvil ( and you wanting me to make a metal one )

if you are writing in English then Vice is the correct spelling if you are writing in American then it is vise the English language comes from England ( the clue to this is in the name ) it was not invented in America, America copied it miss spelling many things and changing it

there will be many places local to you for mild steel, some are expensive and some cheap, some will only deal with big customers others deal with anyone. depends on what you need and in what quantities

lat me know when is convenient for you, we are normally open from about 9.30am to 5 pm, the forge may be going from about 11am most days

the fire in my forges is roughly conical, it is controlled by depth of fuel and airflow, airflow is controlled by a ball valve. turning the air down to no more than is needed saves fuel, come and visit for a chat when you can. have just got back tonight from a weekend of demoing at stratford on avon and need a little rest now and then to unpack and to get ready for the next event I got a message from someone here, thank you to that person

hi Nick how you line my forges depends on fuel you use, coke, coal, charcoal, peat and many more, simplest is coke, one shovel of sand in the bottom, coal or coal some firebricks, peat not sure yet

the frequency determins how many of the motor poles pass per second, change the frequency and you change the speed, keep the frequency the same and lower the voltage and the motor will try to run at the same speed but with much less power so can stall or overheat. here 2 or 4 pole motors are most common but you also can get others meaning the most common motor speeds are about 2850 and 1425 rpm, it the us 2 and 4 pole motors will run faster so your common speeds will probably be more like 3300 and 1750 at a guess. with DC shunt motors you vary voltage to vary speed run a motor expecting 60 hz on 50 hz as long as voltage is correct motor will run a bit slower. the magnetic field in the motor rotates at a speed determined by the frequency and that frequency is not determined by the load, if the motor cannot turn that fast due to the load on it it will get hot

altering the frequency of the ac is the best way, feeding a 240 volt 50 hz ac motor with 110v will stall it under even slight load. most motors I work on are 415 volt and I can vary the frequency from 25 hz to 300 on some if the motor can take it

I have what may be the worlds smallest forging press, it weighs about 66 pounds, just over 10 tons, can do a stroke in less than 1 second, and I can set the stroke to within a few thou in both directions. I have lots of large rivets but may think about smaller ones

great tooling, may suit a forging press more than a hammer but how to load faster and eject?

hi there Medi I do not know but one of my customers in the shetlands told me his grandfather used peat in his forge, have not heard about how it went and I believe he had coke to use up first
