  1. to run it faster you will need a bigger motor and that means more starting current until it gets the flywheel up to speed

    larger motor pulley means needs more power to turn flywheel

    there will be a limit as to how much starting current you can get as most houses these days dont have a very heavy supply, my house has a 60A supply but that was built in 1950, my workshop  has a 3 phase supply but that is on a farm

  2. starting current will be a bit more than 13A, if you know a local sparky talk to them.

    turning the flywheel will mean a lot of load to get it up to speed, it will be like starting your car engine with it in top gear and getting it to 90mph in 3 seconds, when the motor is going it will take a lot less.

    reduce the pulley size on the motor to run the hammer

    you will want that same power and try working out the correct pulley size to keep the flywheel at the same speed it was before

  3. welcome to IFI

    there are plenty of things you can learn here, spend some time reading the forums

    there are many things on youtube but a lot of it is rubbish ( and some is dangerous rubbish ) so watch things that people here recommend at first until you know a bit more

    I would suggest any video by joey van de steeg known here as technicus joe, or any video by people on this forum, if in doubt about anything ask here

    do not worry about your English, there are thousands of posters here to whom english is not their first language

  4. from here it looks like a lot of US stuff actually originates in asia or south america like snap-on and harleys and lots of other stuff, from the makers to you then a tariff when you send them here, also you need to export to be able to import and one of our problems here is outsourcing so we buy things made in other countries and then complain about no jobs making things here, people want cheaper and quality drops.

    then you get things you cant import to the US, I make armouring tools including ball stakes from ball bearings up to 4" diameter that I buy new but it is against the law to send them there due to some US helicopter maker buying bearings from china and a helicopter accident

  5. 2 hours ago, Reeltree said:

    Right , sometimes we send our raw materials oversees , have it milled and such then shipped back here, was just wondering if the tariff was say like a reentry tax, trying to get the milling to return to the US

    You may end up paying a tariff both ways because if you add a tariff to goods from here we can do the same to yours, like recently an aircraft maker in the UK had a 300% tariff on sales in the us imposed, such things can work both ways or even mean places dont buy your goods

    protectionism of one area can affect others that are unrelated

  6. mostly we used coke until recently with nothing but a little sand lining the bottom of the forge but as it is harder to get here now we have switched to coal and are using a bituminous coal mostly and sometimes some welsh steam coal.

    we needed to reduce the size of the fire a bit so we added some hard fire bricks just over 3" deep, forge is 6" deep in total

    it seems to be working well so I thought I would post it here

    2 pix of my forge with no lining at all then some pix of adding bricks and lighting it with charcoal and then onto fresh coal.

    we coke the coal and gradually move it into the firepot

    pix of forge we added bricks to are by john who wanted to try this to see if it worked better and it does, we can now supply bricks with forges if people want

    the firebricks we used were from old storage heaters as we can get these, they have been in use most days since the start of the year

  7. so you use at least 10 times as much fuel as you need to costing you in a week what it would you to buy new ones.

    a car brake disc / rotor is a much better size for a small forge

  8. is that the only marking on it? no handling holes? numbers what does it look like underneath?

    if you had read the post you just quoted in full you would know a lot more looks to be forged not cast value will depend on maker, size, condition, and where in the world it is is it london pattern, soho, or anyone of a hundred more types what condition is the face in??  what was the result of the rebound test?

  9. they are generally for low pressure as are ones from fork lifts, a lot I have seen operate at 100 to 120 bar, personally I would buy a new cylinder so you know the specs and these days they are quite cheap.

    the ones I get are 200 to 250 bar and I can get the bore, stroke, end fittings I want
