tjo, då jag inte kommer göra nåra fler små engelska hjul så tänkte jag visa lite hur mina va gjorda,texten är på engelska då jag postat detta på ett amerikanskt forum innan å orkar inte översätta

ok this is a WERY simple english wheel that i have made a bunch of now,there are no interchangeble dies,instead the dies are standard bearings (SKF) and the frame are standard box tubing,i'm a simple man with simple tools so have some tolerance
all measurments are in millimeter (1inch=25,4mm) so you'll have to get your calculators to change the numbers
frame base,100X50X3-4mm
1= 490mm cut 45'
1= 530mm cut 45'
1= 400mm 90' both ends
weld the 45' bits together to form an L at 90',then weld the 400mm pice on the 530mm at 260mm from underneath the 490mm piece,now you have the base frame
cut a piece of 40X40X4 tubing to 250mm, i choose to do the ends in my lathe to make sure they are perfect,
,drill a 5mm hole 80mm from one end to tap 6mm tread and one 12mm hole 30mm from the other end countersink the edge on the 12mm
cut a piece of 32X32 solid bar to 170mm,
again do the ends on the lathe,
as you can see i have rounded the edges of the solid bar,this in tha lathe to make it fit inside the 40X40,drill one end with a 6mm drill 10mm rom the end and 7mm from the edge,after that drill one 18mm hole in the end of the bar,this for the up and down control of the lower die,
cut a treaded 20mm bar to 230mm and do one end like shown in the pic,outer diameter 18mm ,match the groove to the 6mm hole in the solid 32X32,
from a 90mm long M20 nut cut a a 30mm bit of then drill 3 holes to tread 8mm,
cut 3 pieces of 8mm bar and tread both ends to 8mm,10mm and 15mm long,
fit a 8mm nut to the 15mm end and a plastic knob to the 10mm,you now have 3 of these,
mount them to the 30mm M20 nut to create this,it's the handle for adjusting the lower die
drill and tap a 6mm hole in a 90mm M20 nut 40mm from one end
match these peices and put them together like this,32X32,treaded bar and M20 nut and slide it in to the 40X40mm
make sure to cut a groove in the end of the treaded 20mm bar or else you cant dismantle the unit later on
put the pieces togehter and line them up like this and tack weld the 20mm nut make sure you can turn it and it don't bind,
remove the treaded bar and weld the nut firmly and grind your welds down (if wanted),i again used the lathe to make this tidy finish to the bit,and here it's assembled again with treded bar and handle,
now it's time to make a simple jig fo make sure the upper and lower dies align,and for this i cut a bit of the 40X40 tube to 250mm,drill a 12mm hole 170mm from one end and cut an acces hole on the opposite side to gain acces to the hole from inside,
put the adjusting bit inside the jig,
cut a piece of 50X10mm flat bar to 100mm and drill and tap a 12mm hole 20mm from the edge
bolt it to the jig with the grease nipple holes in the adjuster facing you and align it to the frame base
if your happy with the alignment weld the adjuster and the 50X10 piece to the frame and grind down your welds (if needed)
now it's time to machine the bits that holds the bearings,one bit 25mmX35mm (widhtXdia) with 2 grooves 3mm from the edge for the locking rings,drill and tap a 6mm hole trouh it
and one bit 35mmX50mm (widthXdia) with a 12mm hole,NO grooves for locking rings yet!!
cut 2 pieces of 40X5mm 55mm long and drill and countersink a 6mm hole 15mm from one end in booth,
mount the lower bearing to the first bit machined and use 2 M6 by 16mm countersunk hexbolt to secure the unit to the 40X5 flat bar pieces,looking like this
fit the upper bearing to the 50mm bit and bolt it to the frame in the treaded hole using a M12X40 hex bolt
adjust the adjuster so that the lower bearing assembly barely cleares the upper and align it as good as you can,
then spot weld the lower bearing mount to the adjuster
and remowe the bearings,use a scrap piece cut to 25mm to make sure the lower brackets stay in place,weld solid,and grind to desired finnish,now you can measure the upper bearing for the grooves
and machine them
desmantle and paint and refit all components
it shoul look something like this (maybe better)
