Hi Lads, After the ram jammed on my Bridgeport , the whole machine ended up having to be moved off the cemented in base situated in the corner of the workshop to gain access to work on the mill. As you can imagine this was a proper pain so I have decided to make a jackable frame with castors on it so the mill can be moved if needed. It will not be the sort of thing you can wheel in and out each time you want to use the machine but should make it easier to move if it needs worked on or if something large ever needs to be mounted on the table that would normally be hitting the wall or other machines.
So after a Google search or two I had a rough plan and a pile of scrapyard related materials, as usual my build was to use what I had rather than build with what you would choose in an ideal world.
This is the mill as its been standing for months in the middle of the floor on rollers

This is the plan

These are the raw materials to construct out of, I thought the orange formed plates might have been included but they were too narrow for the castors to fully rotate

Cut up the large angle into lengths on the big bandsaw , its working nice now its been repaired
(http://i1167.photobucket.com/albums/q631/micktoon/Madmodder%202015/Bridgeport%20frame%20005.jpg) (http://s1167.photobucket.com/user/micktoon/media/Madmodder%202015/Bridgeport%20frame%20005.jpg.html)
All the components cut out, the castor supports had to made from two bits of 5 x 3 inch angle welded together to make some channel , I notched the corners of the large 4 x 4 angle

Draged the welding table over and cleaned up the angle with wire brush on a grinder, the angle is 100 years old or so, reclained from a fire escape, its been lying about for 20 years but I knew it would come on handy one day !

The castor supports were tacked then welded top and bottom

Then the frame all welded up some arc and mainly MIG , I don't think it will come apart anyway. The nuts are M28 or 1 1/18th ish, the plates welded behind the nuts are to give more clearance for the bolt head. I also added a towing eye that was lying about that might come in handy

Next job was to drill four 20mm holes that the mill will bolt to the frame with, used the mill itself to do these with

A coat of machine green paint to match the mill

Then when that was drying it was time to do the bolts and plates for jacking. I turned points on the large studding , drilled recesses for these to locate into in the plates , then welded the nuts to the studs to make the large jack bolts and also the smaller M16 bolts to bolt the mill to the base, again these were made as I already had studding lying about

The finished frame ready for the mill to be mounted, Otto my quality control hound looks bored as he found no defects ! The frame is a two man lift type weight now !

The mill mounted in the frame and bolted down, I used the chain hoist to winch it up and my mate Dave quickly rolled the frame under, it takes two people to push the mill, the castors I used were the hard rubber tyre type so maybe cast iron would roll with less effort ? Anyway it does the job and is movable with a bit of effort it jacks up level once in position using the jacking bolts, the splash guard fits ok too

I would say the basic idea is good for most size milling machines really, dual purpose as you get good jacking points to level the machine but also much easier to move when needed.
Cheers Mick.

Very nice Mick :drool: :drool: :drool:
I have some GREY paint for you once the green primer dries :lol: :lol: :lol:

Mick
Very nice trolly you have made. I am sure that that will give a few MoDDers ideas on how they can build one for their large mills or lathes. Very nicely shown and nice photo's. :D :D :D
Cheers :beer:

Nicely done,Mick,good solution. :clap: :clap:
Now,what about fitting a set of casters to Otto,it would make it a lot easier to move him from under your feet :) ...OZ.

Great design. Have the same machine also sat on rollers for last 6 months since I moved house. If I can find some castors with high enough load I think I'll do something like that. Thanks.
Did you already have the wheels?
-
Nicely/ neatly done Mick! :clap: :clap: :thumbup:

Hi Lads thanks for the comments, I am trying to have as many things as possible on wheels / castors as sick of having to move things and the more ackward something is to move seems to equal the more often it will need to be moved lol.
I already had those castors Porker , I spotted them at the scrap yard on some big old fram , probably from the shipyards, I tried to look up the loads rating but could not find it , they are 5 inch cast wheels with very hard low profile rubber tyres, probably not the idea ones if you asked at a castor suppliers but I wont be doing too many miles I hope.
Oz , as a rule Otto never stops still long enough to fit the castors to him, that was a rare moment of boredom in between bringing his ball or bugging me to take him for a walk, he is 12 years old but still has plenty energy.
My next plan is to fit two small wheels that just miss the ground to the rear of a few things and then have a hitch type locator on the front that a 'wheeled crow bar' type invention can jack the item slightly so it will pull along on the rear wheels :smart: still thinking about how to do it at the moment.
I think a similar type frame I have made for the bridgeport would work great on a smaller mill as you could wheel it about on your own, so you really could just wheel it out , level it when needed and return it out the way when not getting used.
Cheers Mick.

I think that's brilliant putting a Bridgy on castors.
Makes it far easier to wheel to the scrap yard. :poke:

Very nice, Mick, nicely done, and nicely finished off, as usual. :clap: :clap: :beer:

well dune mick

Nicely done.
The "wheeled crowbar" is a neat idea. Go to ebay and search for "paddock stands". These are wheeled crowbars used to raise motorcycles of the ground at one end to enable them to be pushed around and to facilitate maintenance. The bike is fitted with a bobbin on both sides, and a forked arrangement on the end of the stand engages with these. (Many modern bikes are heavy and only fitted with a side stand, but some come complete with locations for bobbins)
The different designs might inspire some thoughts.
