Hello everyone, I have been lurking in the back ground for a little while so I thought I could introduce myself with my first build. I've read through sshire build thread over and over again so I hope I am ready, I have purchased most of the material and while at the midlands show on Friday I picked up all the unf taps and dies required to complete the job, I do need a supplier of the nuts and bolts in the uk any help would be great.

I have a smallish workshop with a harrison 140 lathe and also a aciera f3 milling machine with a cabinet full of tooling.

I hope this post is ok and not breaking any rules,

Cheers gaz

I tend to substitute BA fixings on American designed engines

Thanks guys I may have to convert the drawings to ba threads unless someone outside the uk would be willing to help.

Thank you Jason I've just found a company in the uk called Westfield fasteners they supply most of the fasteners I require which is a big relief as I didn't want the taps and dies to go to waste

Welcome to MEM gaz!

I recently picked up a tooling cabinet very similar to yours; I was told that it was for some sort of a German made grinder. It was painted blue and all the shelf inserts were custom made for the tooling that is used to hold. It is in process of getting repainted and new inserts made for the shelves. I hadn't thought about using one of the shelves for collets but after seeing yours I just may do that.
Will post a picture when I get it completed.

Looking forward to seeing your Farm Boy progress.

Dave

Gazzaleachie · « **Reply #9 on:** October 18, 2015, 09:25:55 PM »

Hello Dave, that's very interesting I look forward to the results, the cabinet is very well made and appear to handle a lot of weight the slotting head on the bottom shelf is a fair lump.

All the best gaz

Dave Otto · « **Reply #10 on:** October 18, 2015, 09:43:20 PM »

Yes very well made; that is one of the things that attracted me to it, that and the very interesting swing out shelves. Can you make out what is says on the front of the shelves?

On the front of mine it reads "versa tool" patent no 803676

Wow where have the last couple of weeks gone , my day job is working for an hgv main dealer and I'm on call 24 hours a day seven days a week so one day blurrs into the next, oh well I've had some time off and have made progress of sorts.

Front frame block all squared up and ready for some layout

Boring work in the lathe

It didn't all go to plan when I machined the radius I had marked two lines on the block and not thinking cut to the second scribe which was wrong, oh well start again this time spot on, I used the scrap part to check set ups for the next steps.

Whattya say Gary. Terrific looking assortment of tooling as well as storage. I especially like what you have done to protect the bed of your mill right up to the vise edges by the making of wooden covers. I never really thought about it much as in school we were beat to death if we were caught having set anything on the mill bed. I will be stealing this idea if you don't mind

Hi Jim I stole the idea from Tom Lipton who's Chanel I watch religiously on YouTube, makes cleaning the mill up very easy, And also as you say you can put things on the table and not damage it. The plywood covers have strips of plywood underneath which locate in the t slots of the mill.

bit more progress, while the milling machine is working away on the engine frames i made a start on the cylinder liner, i turned the liner between centre's and the drilled and bored to size, now all I've done so far is hone the liner and its very smooth does it need polishing? thanks for all the positive comments guys more progress to follow this week. I've also add a picture of the other project I am helping a friend with.

Gazzaleachie · « **Reply #27 on:** November 18, 2015, 11:07:06 AM »

My mill sits at a rather uncomfortable height so I have to move to other parts of the engine to save my back so while having a break from the rear frame I've made a start on the crankshaft the crank pin is on size but all other dimensions are oversize until live made the bearings and finished the frame, I used a piece of en8 round bar for the crank?

Now back on to the rear frame again all roughed out it's not perfect but looks ok

All the best gaz.

I have just joined the forum, nice work there. The last place I worked at before retiring had a mill like yours, it was unused for 12 or more years and I was tempted to ask if they would sell. However it is on a first floor and would cost to much to remove and transport. They may move premises one day so I keep in touch. It would go well with my Bridgeport.

Gazzaleachie · « **Reply #38 on:** November 29, 2015, 03:03:26 PM »

I've been working on the water hopper for a couple of days now I thought I had everything set up smack on but obvously not at the cylinder opening is slightly off centre very annoying . Anyways let me know what you think more progress to follow.

Just a quick question are my post a bit over the too with picture or would more text be welcomed.

The water hopper still requires the one inch radii on the bottom to blend in with the rest of the frame work.

Cheers gaz

Don1966 · « **Reply #42 on:** November 29, 2015, 04:50:25 PM »

Nice work Gaz but I am confused you put the liner in before you bored the hopper. Will the liner be in the water some way?

Don

Gazzaleachie · « **Reply #43 on:** November 29, 2015, 05:41:57 PM »

Hi don, no the water space is 1.5 inches deep and there is almost 1/2 inch before the liner also the liner is only a push fit in the hopper so I removed it after I had got the correct fit, I hope the makes sense all the best gaz

Just a quick question are my post a bit over the too with picture or would more text be welcomed.

Gazz: In my opinion it is difficult to put in too many pictures. I find it helpful to add text explaining what's in the pictures and the thought behind the set-ups, any difficulties, etc. These are the advantages of a forum over a published article, there's space for more detail. I'd suggest that you let your patience be your guide, put in as much detail as you patience allows. If anyone finds it too much they can skip ahead.

Nice build, a hit-and-miss build is on my short list. Thanks for taking the time to post your progress.

Gazzaleachie · « **Reply #48 on:** December 02, 2015, 11:36:22 AM »

Hi guys I made a start on the the radius on the bottom of the water hopper on Monday after a very long day at Daf trucks training center learning about the new advanced emergency braking system very cleaver stuff.
Anyways my mind was fried and for the life of me I couldn't figure out for the life of me why I was unable to turn my rotary table after setting up the hopper.

Well it will never turn if you use a t nut and clamp the whole assembly to the mill table duh! So I give up go inside and have a beer. Tuesday was round two at daf so after the exam I came home and just relaxed.
Today i made a fixture plate which I bolted to the rotary table and then secured the part to that problem solved.

This us the last of the large part roughed out now all parts need the varous holes drilling and tapping

All the best gaz

10KPete · « **Reply #49 on:** December 02, 2015, 11:56:41 AM »

Hi guys not sure if there is a section on this forum but I want to use gib head keys to secure my flywheels as used in full size engines now I know the key should have a 1/100 taper but the keys for this engine are 1/8 x1/8 so what would be the angle required to set my slotting head at for such a small taper if I've worked it out correctly I have it as 0.0015 ?

Hope this makes sense cheers gaz

Dave Otto · « **Reply #55 on:** December 05, 2015, 07:50:16 PM »

Hi Gaz

I have been enjoying the progress on your Farm Boy project.
I believe that the taper is 1/8" per foot; that would work out to an angle of .5968 degrees.

Dave

Jasonb · « **Reply #56 on:** December 05, 2015, 08:20:30 PM »

1:100 would be 0.57deg

You may find it easier to pack one side of the flywheel, 1mm of packing for every 100mm of diameter. Thats how I cut teh tapered slot when making bushes to guide my keyway broaches as well a sgib head keys, cotters and wedges. This is a cotter set up for 1:48 or 1/8" in 6" or 1/4" per ft. You can also put packing under the vice

Happy new year , Time for an update,

First job to tackle was drilling the 3 cylinder mounting holes these are 3 inches deep and a bit of a worry but it all went well with no hick ups i mad a drill jig to aid in correct alignment.

I had been putting off securing the frames together until i was happy that eveything was going to fit, i drilled and tapped the holes as suggested in the plans, then used jb weld to glue everything together.

A good friend of mine was giving away his pantograph so it was quickly snapped up and dropped round to my workshop and wired up to my 3 phase converter i have had a quick play around with a small tag its only a mock up and a better one will be made at a later date. Im keen to use this machine to make some of the smaller parts so we will see how that progresses.

Ive also bored the hubs of my flywheels and put everything together up to date im very pleased so far, i have also made a start on the cylinder head but have been struck down with a cold so dont feel up to doing much.

All the best Gaz

Gazzaleachie · « **Reply #68 on:** January 17, 2016, 09:07:59 PM »

Update time

One of the jobs i was not looking forward to doing was locating and drilling all the holes in the cylinder head and i had hoped to have a dro by now but i still cant make my mind up so a used good old fashioned dti.

Once i was happy of the location i set about getting tooled up and ready

Now my milling machine was supplied with a microscope ????? far too precise for me but hey worth having a play the scribe line was done using the mills center which looked horrific under the microscope.

holes all drilled and reamed where required.

Now I have been looking at ways of using the panto graph for more than just making signs! So i have been scaling up some of the parts by a factor of 3 and today i made a template using some 4 mm plastic sheet.
I thought that using a 6 mm endmill i would need an 18 mm follower but this was not so my part came out under size by about 0.98 mm so i adjusted the follower to 20 mm and this done the trick. Also on the practice piece i used a 60 degree spotting drill which did not give a very clear result so i used an engraving cutter on the second part this gave a much better center to pick up when i come to drill the holes. I should add that i formed the radii using the horizontal mill attachment first then transfered the part to the panto for final machining.

This is the first attempt looks good

Then the second attempt much better

Thats us all up to date i now need to mill out a fixture to hold the rocker arm ready for drilling which i hope to finish tomoorow......................

all the best Gaz

Just a little update, I finally brought myself a dro from machine-dro it arrived the very next day, I had a day of fitting various brackets to fabricate but its all on and working like a dream. A couple of days later my wife called me while i was at working in a bit of panic saying the fuse board in the house keeps tripping out, I quickly came home and tracked the fault down to the milling machine switch gear? I didn't want to repair the switch gear so a quick google put me onto power capacitors supply Variable Frequency Drives now i have never had anything to do with these but from what i had read on the internet i could bypass all my switch gear and run my motor direct, So i ordered the drive and fitted it to my motor wired correctly but i just didn't seem to have any torque so worried i called power capacitors and spoke with Pete we quickly figured out that my motor which is three phase was not duel voltage and that the only solution was a new motor. So i ordered a larger motor and that arrived the next day more fabricating and we are finally up and running again.....

I hope to update this thread in the next couple of weeks.
