Mini-Mill #4 Post 1

Finished building #4 Mini-Mill for my friend. He has been hounding me to build him one so here it is.

jerry-

Here is the rails for the mill with the throttle handle.

Used 1/4"-20 thread inserts for holding the dust deflector arm when assembled.

Here is the 1/2" thick block for bolting the bar to the mill. Holes are on 1" centers.

Here is the basic throttle piece that bolts to the saw handle. It is made from 1" angle that is tapered to match the saw handle.

Nice work, very clean and tidy.

More pictures of mill build.

Here is view of the the inside of the throttle assembly. I used 1/4" thick material for where the throttle arm bolt pivots to keep stable when in operation.

I welded square 1/4-20 nuts on the outside of the throttle assembly for bolting it to the saw. I like thinks to look right so I made sure the nuts were set at 45* on the bracket. It's just me...

A better shot of the 1/4" stock used for the pivot of the throttle arm.

Fully assembled and painted.

Final assembly pictures.

View of saw mounted on mill frame. The bar is a 24" Carlton using 3/8" chain.

Here you can see the insulation I have attached with zip-ties to the spring loaded dust deflector. I'm hoping to use it next week and give it a try. If I find that the stream of dust is to strong for the spring I can always use a stronger spring.

Here I have added a second compression spring to be sure I get full return of the throttle arm assembly.

On the throttle assembly I used a strip of leather with 2-sided tape on the opposite side. On this side I cut a piece of 1/8" thick aluminum that is also 2-sided taped with leather. It goes between the the saw handle and the two lock wing-nuts so I don't gouge the handle with the wing-nuts. I have found that leather doesn't slip even with oil on it. I have used leather on other compression applications, and it works quite well.

Here is a picture of the assembled mill on the non-bar side, you can see the dust deflector how I mounted it to the two thread inserts. It pivots at the bottom with a spring going to the piece I welded to the mill rail.

Mini-Mill #4 Last Post

Here are the last pictures of the mill build.

Picture is of the throttle trigger arm and how it is bent. I welded it to a 1/4"-28 aircraft stainless steel bolt. It is held on with a NyLock nut and adjusted to limit side movement.

Here is a good view of of the dust deflector and how it is mounted and attached to the recoil spring.

On the throttle handle I used a piece of shrink tube to keep dust out and to keep the cable housing from coming out during milling. I hate things wobbling around.

The trigger pivot is adjustable by moving the entire throttle assembly up or down on the saw handle.

Final shot of the mill. My friend came by today during his lunch and said he can't wait to see it work. Me too!

Thanks Bob,

It's been a slow build on this one. Had the wife in and out of the hospital a couple of times. She is doing better now.

Very nice build Jerry; I always wanted to get into milling just do not have the resources yet. You have a gift with your talents. Thanks for taking the time to post, it is an inspiration.

Hey! I would like to see a better shot of the mustang in the background.Put the saw in front of it so the mods won't holler

logbob · Feb 25, 2012

After seeing this I am never gonna post the pictures of the junk I built !!!!
I envy your welding skills...

MHouse1028 · Feb 25, 2012

Wow very nice it looks Bad Azz....

Ive been trying to figure a nice clean way to run a throttle remotely for a long time. You made it look so simple. Nice work.

Here is a picture of my GT-350H. When I had it repainted I went with the white/blue stripes. At that time no one made the GT-350H stripes in blue. The car was a red/gold rental at the Oakland, Ca airport. I bought it wrecked in 1971 and took two years putting it back together.

Here is a picture of it in the open.

Thanks for the kind words everyone. My hopes is that someone aspiring to build their own mill will see these pictures and give it a try. Seeing a picture may give them an idea on how to build something for themselves. I built this mill for a friend and he can't wait to use it.

Some nice work .

820, Very very impressive! Your attention to detail and ergonomics is amazing. I like the remote throttle a lot and just might have to try to duplicate it to some extent on my mini mill. Thanks for all of the detailed pics. Your friend is very lucky!:msp_thumbup:

Thanks PT,

Let me know if you have questions, it's a pretty simple piece to make.
