Elbow Engine

[PhiberOptix]

WhoooHooooo look what arrived last night


the bronze offcut to make the replacement cylinder

also working on a saddle stop/mount for an X axis dro

and the start of a machine vice

as I am already set up for milling i will do some more on the vice first then change over to turning mode do the cylinder and pins for the vice and I want to use round bar on the stop in place of Chamffers then put the rapid indexer on and over into drill mode finish the cylinder

tomorrow I want to make a jig by cutting a 45 degree vee along two edges of a right angle block of aluminium
I plan to use the block by clamping one end o a piston in one vee heat up the middle of the piston bend it into the second vee and clamp in situ til cool and see if that gives me the required 90 degree angle on the piston

I have a just barely started elbow engine as well thanks to you. ;D

Its looking great Andy, despite the small glitch with the one cylinder. I am looking forward to the final stages of construction and seeing it run.

Me and you both m8 and theres plenty enough bronze to get 3 cylinders (IF NEED BE) lol

I cant wait till my project list gets down to only half a dozen

Great stuff I trust you will be posting your progress too

right here we go

the vice Base is done - just stopping for a munch and a coffee

Now to start on the new cylinder

ill be back with pics

 

[RobWilson]

Very nice vice Andy , It will be a handy addition to the workshop :bow: :bow:

Regards Rob

Good luck with the cylinder ;D

turned down OD to size, parted off, and faced off (wrapped in aluminium from a beer can)

piloting the center hole

main drill after pilot drilling
(pilot drill still visible on the compound slide behind the toolpost)

holes already center drilled and piloted and main drilled

Reamed the cylinders out

And the pistons in the cylinders proving alignment with the holes of both cylinders is a match

Ah...the beer can wrap...Robert (Foozer) put me onto that.
I'm interested in that vise/vice too. Keep the pics coming.

 

[Krown Kustoms]

glad to see the second one came out ok, I would have made 4 or 5 before a good one.

Nice recovery Andy,

just for you Zee

sorry no coins in this one lol
but you can use the caphead for scale its an M6

 

[Krown Kustoms]

Are you using plans or one off?
it looks good, what are you using for finish I dont see any tooling marks.

Its a one of a kind m8, done from memory of ones I've seen before,
I am thinking of making a 2 and 1 inch version and also a real small one

The finish is with a fly cutter and a quick burst spray of wd40
and a very slow feed rate (by hand)

I made a vice as a joke one day, someone asked me if I could make him a small one for his dremmel mill.
I made one 1" x .5" It was tiny, it took about 6 hours to build, half way through I was wondering who the joke was on.
I ended up drilling a hole in the corner of it and making it into a keychain, one day I picked up my keys and it was gone only the ring was there. I will try to find a pic, after my last accidental file deletion I think I lost all of those pics.

Nice one Andy Thm: very pro looking

regards rob

big brother and little one born today, just needs a polish
I will not be using this one its just an ornament for mantle piece
tho I am toying with this idea of having a model engines flywheel powering a
model workshop complere with lathe mill grinder power saw tool chests etc etc
all driven via a belt like in 'Fred Dibnars' workshop
the new baby vice could be used in that senario

tomorrow its making the jig time for the bending of the pistons
then Sunday its over to my m8s workshop and on his oxy acetylene
wish me luck

 

[arnoldb]

Nice job Andy, And - Good Luck !
Regards, Arnold

 

[zeeprogrammer]

Neat idea for an ornament. I'll have to remember that.

Good luck!

 

[RobWilson]

Hi Andy , very nice, great idea about building a steam powered workshop

Regards Rob

 

[Krown Kustoms]

Very nice, you complete projects faster than I make parts.

bending the pistons and making the jig
Milling in a slot with a ball nose cutter the same size as the pistons

My m8 got hold of my phone and photographed me, here i am milling on his XYZ 4000 CNC machine

MIlling out the corner of the jig

First Piston in the jig and held in place in a vice ready for heating

Heating up the piston ready for bending

piston bent and clamped while it cooled

the finished piston

three finished pistons

Sorry its been a while but ive been busy with a serious case of projectitus
Angle plate
2 plates welded together with webs (Thank You Rob)
milling the faces true

QCTP
Made this a couple of days ago works a treat

tool holders
made these after the QCTP

Gear holder (got sick of finding the right cog in the box, this way they are kept in order)

cutting tool height set tool/guage

tap wrench (copied from some one elses idea)

mandrill handle

tail stock tool tidy
