Been busy with a health issue with my Son. It's something we need to sort, and we think we have a handle on what it is. but it's been keeping me busy
I started to build on something I've had on the list for a while, only because it's some thing I can start and stop when time allows....and my leg is willing!
A die filer.
Now I have had the Martin castings for a while. I realized after I bought them, that I didn't have the bench space to build and use this kit! You need a motor too!....so the castings sat idle, albiet fondled occasionally.
Then I saw this on the Web, Its a die filing attachment driven by the lathe. ......and it clicked.
So I got started
-
As this die filer will be driven by Samantha Bell, It doesn't need a base. So that is the first thing to come off.
-
Next I set up and bored the casting for the bushings. I made up some out of bronze and put them in
I then made up a 5/8 reamer out of 0-1 ground stock and reamed the bushes to size.
-
I made up an arbor, and it drops right in pretty as you please.
Next was to bore the casting for a Blank MT2 arbor I bought off the bay....
And here is where I am currently.. Next is the table, I wanted to do that in lathe, but it's just too big a bite for Samantha....I'll do it in the mill

Dave,
Nice bit of lateral thinking. I know what you mean about the size. My recently obtained Excel Die Filer hasn't really got a home. At present it sits on top of hydraulic lift table.
I have sorted out a selection of files for it, but now need to draw up a pattern to have a couple of arms cast to match the missing ones and get them machined.
Colin
-
I'm going to add a top file guide roller, and some hold downs.
I'd like to have a reciprocating arm like the Stark as well...but I'll get it running first
Dave
-
Martin Model has a selection of die filer files for this machine, so I just ordered up 10
3 square
3 triangular
4 rounds
All 3 1/2 inches long

Nice looking project Dave, and a good start on it too.

Ya know Don.....it might be.....I thought I bought it....but my name may be aloishis.....
Dave
-
I know it came with drawings...that I can't find...so I ordered them again....
Dave
-
Hey Don....you are right my friend....April 2013 you sent them to me.
:lolb:
I guess they've aged long enough to machine now huh? 8)

Ok so i faced 3 1/4 inch diameter spot on the underside of the table and drilled the table 1/2 inch in the center.
Next i chucked a off piece of 3 inch round and faced it and put a center hole in then I held the table agaist the stub arbor with a live center. Turned and faced the table. Ill post some pics after I resize them to fit
-
Here's some pictures of the process....it went very easy. I need to reach down to the center a little further....but it's almost done
-
And some more
-
Looks great Dave but hey buddy why do I see rust on that tailstock center, just saying!
:popcorn:
Don

Cause I never took it off when I got the lathe!....I did clean the bearings.....
"Yeah I'll do it eventually"......I said 6+ years ago...
Dave

Table top and OD are turned. I started on the Scotch yoke just squaring up the casting. Next is the swivel plate on the side of the table, and then finish the yoke. There will be a couple of interesting set ups on that. Tonight, I just gave Samantha bell a good bath......She got pretty dirty with all that Iron.
Dave
-
Top of the table is done. next is the pivot bracket...next pic
Nice castings.....
-
Those sure are some nice looking castings Dave. Did you get the files yet? Please post a picture of them when you can.
Bill
-
My castings were super nice also. Matin do good work
Eric
-
I'm thinking that the MLA die filer is one of those casting sets that everyone has, but few have actually built. (I have a set somewhere, that I bought at the APM show in Vermont about 15-20 years ago)
I like the idea of modifying it to run off the lathe. Should be an interesting project.
-
I ordered the files actually they may be home
Mike cut the base off and add a MT2 arbor to the cover and youre done
Iron is really nice Cletus.....
-
I ordered the files from Martin......NICE files. I got the short one, but they're exceptionally nice
I'll post a pic tomorrow....
Dave
-
Dave, am I correct in assuming that the files from Martin do not require any modification for use in the die filer? Looking forward to seeing them when you have the chance.
Bill
-
Here ya go Bill. They are NOS Nicholson die filer files No modifications required. 1/4" shank except for the 1/8th which is 1/8
I got an assortment from Martin. good files!
Dave
-
Thanks Dave. Those look sweet!!
Bill
-
Dave,
If its not too rude a question what do you have to pay for those in the States.
I have modified some files to fit my Excel machine but it would be nice to be able to buy and not have the messing around.

Hey Colin
Here's the order sheet. I chose the buy 10 files at once deal for a discount. I think it was $110+shipping I might buy some more....probably last the rest of my life I suspect.

Dave,
Those files look good. Can you confirm a couple of things for me.
What is the diameter of the shank, I need to ensure will fit in the Excel clamp mechanism. On the basis these are clamped below the table do the files all cut on the down stroke.
Cheers,
Colin
-
Hi Colin Ill measure them up today and report back here
-
Hi Colin
I measured up 3 and got a range of 0.248" to 0.251" (6.30mm to 6.375mm) The shanks are soft.
They all cut on the down stroke
They are made by Nicholson, a pretty well respected file company in the day. and are die filer files, not modified hand files
Dave
-
Dave,
Thanks for that. They will fit in the Excel clamp mechanism. I made some small steel blocks and drilled them out to use chainsaw files. I used Araldite to secure the files.
This works well, so could repeat if necessary for these.
Colin
-
A little more done tonight
-
It's beginning to look like something now
-
It's coming along nicely Dave. Looks good.
Bill
-
Looking good Dave your going to enjoy using it. :ThumbsUp:
:cheers:
Don
-
A little more yesterday
-
Ok its beginning to look like a die filer. On to the crank
-
She lives!!!

-
Yep, sure is. Looking good too!!
Bill

OK made a pivot support and a clamp washer today....I had my daughter helping me on Samantha bell with the washer...she had fun
next is the over arm for top support and the work hold down finger.....then a nice coat of paint to match SB.
Dave
-
the overarm support is done, minus the thumb knob....I'll get to it
Now to make the hold down. I've come up with a very simple design, and I'll get on it tomorrow I think
I know Pictures
Dave
-
Looking great Dave and yeah buddy piccys would be nice... :ThumbsUp:
:cheers:
Don
-
Here ya go Don....
Over arm support for the back of the file. Neatly designed to position and lock up with one thumb knob on the right. Next is another similar assembly with a work hold down finger that will swing and pivot and rise and fall on the vertical post on the right like this one does, but independent of it.....needs a shorter screw....
Dave
-
OK got the hold down clamping block done....no picture as it's the same as the one in the picture above. I'm working on the arm.
The design is a cotter design, and I originally did a .38 radius groove, but I don't have a ball turner that will do that and I don't want to make a form tool for 1 cut
So I'll simplify that design just a skosh....and make it trapazoidal....it'll work the same way, but be easier to machine.
Dave
-
Here's the alternative design....easy to make on the lathe
-
Done!!!
https://www.facebook.com/mcandrew.piper/videos/2372990136311712/?t=1
Works well, Some of my file shanks are a bit long, so I'll need to shorten them a bit...but I'm happy
Next!
-
Very nice Dave!! Thanks for the video too. Should be a handy addition to have on hand as well.
Bill
-
Thats pretty neat, Dave!
I don't remember seeing that top roller bearing on other die filers I've seen. Is that your own addition?
Kim
-
Oh many did..and they had different configurations to fit the files. Some flat wheeled, and some V wheeled. This casting set didn't have provision for one, so I drew one up and added a hold down arm as well.
The arm could be 3/8 of an inch shorter or so....to get closer to the file...but it works well enough and making a new one is pretty easy If I choose to...
Dave

Here's a picture of one with both
