Hemingway Die filer & saw for model engineer

- This comes as a kit of castings with good plans and instructions,
It is designed to fit on the cross slide of a Myford lathe so I have had to make an adaptor to fit my lathe. Using the lathe does give you useful speed control. It does seem versatile as you can fit any type of cutting medium but removes metal slowly when filing.
Thanks for showing the Hemingway Kits Die Filer in action !

Eddy.
Wow, this thing is nice, far nicer than I expected. It looks like a simple and fun machining challenge too. I may get this from Hemingway as my next project.
I think having a saw bow is a big advantage with this machine, but you do have to adapt it to your lathe or build a platform for a motor. a lathe does give you a slow speed and plenty of power. there is some lift to the work so you need to keep a firm hold.
Good to see this in action, i think I could live with the files having a short life rather than ruin hours of work through a lapse in concentration when filing by hand. The plus side with this is that you can take it square up to the line and it will make a much more pleasing result when filing out corners. The most impressive thing about this is the stability of the table most probably because it has an entire lathe as an anvil. Many other proprietary and copy models seem to have a lot of table shake when in operation which even watching the videos at this stage is frustrating me! Good to see that this can manage with a variety of hand files which can be bought anywhere at relatively low cost. The shot of the file tang up was good to see and as with much of this video it explained away very much!
Perfect timing. This kit just arrived as my Xmas project to use on my ml7 !
like the idea , the only down side is the metal / wood dust landing on the ways of the lathe
maibe you can build the add on in line with the pass through hole behind he chuck
you need a longer drive shaft through the pass true hole and fix it to the intoo the chuck from the other side and drive it that way , prolly need to support the driveshaft on the back of the lathe but it can be done , might even be able to mount the add on permanently to that side of the lathe and only make the driveshaft removeable
could even make a sort of pto shaft like on a tractor as the drive gears are on that side of the lathe too
Metal and wood dust land on the bed when it is used for turning anyway so why worry?
Отличное решение для напильника , очень хорошо !
Good video. What saw blades would be used to cut 3/16" (4.5mm) brass sheet, please?
I haven't tried anything this thick but a blade from a coping saw or junior hacksaw might do it, but I think the metal would jump up and down to much unless there was a guide to hold it down. anyway progress is quite slow.
Hey are the rails already milled and ground, or is there any machine work to do on the castings kit?
Hi. The rails are built up from steel strips and need holes drilled, there is plenty of machining to do on the base and table tilting bracket and you need a milling machine to do this. All the metal and fixings are supplied.
@@geoff5269 are the steel strips includet?
I'm going o build this and am interested how you drilled the 1/4" dia. holes in the bow in line.Grateful for any advice.
Nathan, Drill the bottom hole first and you could put this over a pin fixed in the base of the pillar drill if it is tall enough. Also fit a scrap of wood in the bow gap to support it. I don't think alignment is to critical just be as accurate as you can.
Thats a good idea, I have a small universal mill with plenty of height clearance.
The other thought I had was drill top hole (with wood packing) and then pass 1/4" rod through the hole and attach drill with grub-screwed sleeve and drill bottom hole. As you say alignment is only for flexible blades anyway. Thanks for the advice.
Very nice. A question - does a 'proper' die filer use different files, that can accept being used on the back stroke? I see you are using standard hand files; when hand filing, you are supposed to lift off for the reverse stroke, to avoid blunting the file - but this is clearly not possible when using your die filer, so I suppose the adapted hand files are blunted relatively quickly?
I believe an industrial machine would have purpose made files but these are hard to find now. I think the benefit of this machine is you can adapt any cutting blades or files to use in it.
If using the modern diamond covered needle files, they are happy cutting both ways.
Would the diamond abrasive end up on the lathe bed though? Not sure i'd want that.
thank you
Well done
wow
very nice :)
