The Iron Dwarf

im not in the sca, nor have I been to any sca events but....... if a person is short and wants to be a dwarf you could help by steering them in the direction of a historical persona of someone who is also short and there must have been some, were there vikings who were 3' 6" rather than 6' 3" or may...

The Iron Dwarf

sold out of forges, been making more all through the holiday and its freezing

The Iron Dwarf

I have some on ebid at the moment

The Iron Dwarf

ones I have I normally sell for a fiver per 100

The Iron Dwarf

they should be a lot cheaper than that, I have brass and steel flat head and steel csk but only a few round head, will ask at a place near me when I get a chance

The Iron Dwarf

have what looks like a problem buyer on ebay at the moment, will see in a few days. calling dibs on here I think is ok as long as it is only untill size and other things are agreed, then pay up or cancel. EG PB has an instock item on at a very special price and I call dibs asking size and delivery c...

The Iron Dwarf

have sent you a PM dave

The Iron Dwarf

well im not in the SCA and certainly wont be fighting as a dwarf at one of your events, the reenactment events I do go to here in England I trade the metal items I make and working metal is a good dwarfish tradition

The Iron Dwarf

welcome Dave J
looks good to me but im no expert, there are many on here who are!
Im a bit north of you but if you go to the major events here in the UK no doubt we will meet some time.
I go to ILHF, TORM, tewkes and others and may be able to give you a few ideas for making tools as that is what I do

The Iron Dwarf

accept no imitation, real dwarves only!!!!!!!

The Iron Dwarf

a few years ago I had literally hundreds of countersunk headed screws to remove from cast iron plus lots more with normal heads, others had tried and nearly every time the head had broken ( these had been in place about 100 years ). I found out that if I placed a nut over the head or the remains of ...

The Iron Dwarf

you will probably find that without anything else your springs will be over the 15 pounds you are aiming for and you will want more than 3 speeds, you will probably want 3 ratio's and a speed controller.

The Iron Dwarf

they are different hammers, the second one may be a modified brick hammer I think

The Iron Dwarf

as the tube is round but most handles on hammer are oval slightly flatten the tube to get the right shape and it will feel much better then add the fingered grip with some glue or a tape

The Iron Dwarf

AP, take it easy, recover first.
waiting a month is not too bad compared with what some have waited, take in a few less orders.
from what I hear you do good work at great prices so your customers will be happy to wait

The Iron Dwarf

have had delivered today 3 new motors have the metal for 2 anvils except the top plates which I should get this week (anvils need to be made first to be left for the concrete to go off) most of the metal frame parts are cut to size, lots of small details like drilling to do another crank to make, an...

The Iron Dwarf

Thank you John a friend has put forward testing the impact with a plastic strip that you then measure the width of after drawing it through the hammer so the hits are different places, have heard of a system years ago called plastigauge or something for measuring bearing clearances in car engines. I...

The Iron Dwarf

maybe, if I can get the sort of equipment for measuring the speed in the final few mm we can work it out. a reason for my design using an 'unstable system' like it does to is make it work with different weights of hammer and still be controllable. so far with the same springs and only needing one nu...

The Iron Dwarf

at a couple of recent events I taken a portable dvd player and a 4 min vid of my hammer hitting first a piece of lead and then some hot metal and passed round the actual pieces, since then it has been improved quite a bit. I plan on doing the same in the spring events and will see what else I can do...

The Iron Dwarf

on mine I control the speed of a motor that is geared down to give 220 rpm at its normal speed, the motor drives a crank that is not directly linked to the arm with the hammer on it but has springs . going slow the hammer moves, going faster it is thrown from one spring to the other. a calculation l...

The Iron Dwarf

looked at the tekscan stuff and it is for very low pressure like 7 PSI and pressure rather than an impact. will ask some digital gauge people to see what they think. maybe if I can get the KG force of mine and a few other types of hammer to compare it will help. at a couple of recent events I shown ...

The Iron Dwarf

been chatting to the guy who makes the springs in my hammer, yes calculations make my head hurt and his too so a load cell may be the answer

The Iron Dwarf

have been sent a link to a digital force gauge with a load cell but at about 2000 US$ it maybe something I would not want to hit that hard

The Iron Dwarf

I feel your pain Wade, mine also varies the stroke length with speed but using the stored energy in 2 opposing springs there is quite a long dwell time at the top and some at the bottom and it can be seen that each stroke starts slow and increases in speed as it nears the anvil so near the moment of...

The Iron Dwarf

I think the speed the hammer is traveling is not consistent, as the stroke starts it is slow then it gets faster till it hits, will that complicate things? will be seeing a friend into maths and may try filming it with a rule in site to see how fast it moves in different parts of the stroke, how muc...

The Iron Dwarf

I have been developing a small power hammer and cannot think of a way of measuring the force it produces. it is an 'unstable system' using springs, the static hammer weight is 9.3kg at the moment and speed is varied to control stroke length and power, max stroke I have measured is about 30cm at a sp...

The Iron Dwarf

which part of the world are you from Pinoc?
on this forum there are members just about everywhere and maybe some near you

im in England, also you may want to add it to your profile

The Iron Dwarf

actually even though it is not fixed down it does not move, one side of it on the floor is a stack of heavy plates and it cant move backwards so maybe it wants to move in one of those directions

The Iron Dwarf

now the v1.2 is installed I will start on v2 by ordering the motor and getting the parts ready for the new chassis, this week getting the metal for more anvils. the casing of the next 2 anvils is 152mm box section about 8mm thick ( 6" box 5/16" thick ) with a top plate 25mm thick mild steel ( 1" ) a...

The Iron Dwarf

just upped the static hammer weight from 8kg (17.6lbs ) to 9.3kg ( 20.5 lbs ) and max motor frequency from 34hz to 45hz and seems to have a lot more power now. bearing in mind this machine only weighs about 150kg in total ( 3cwt ) and is not fixed down it is remarkably stable and hits real hard, sti...

The Iron Dwarf

have built a small hammer that hits pretty hard, still testing it to see if anything breaks, unfortunatly im on a different continent
