Started a new project this week. Making an angle plate to use on the mill.

Nice material to work with 1/2 X 6 ground mild steel from McMaster-Carr.

Cleaning up the plates.

Basic shapes completed

Cutting the notch for the upper plate.
Using the lower plate and clamps to stiffen the part just in case but it cut very nicely. Not quite like aluminium but certainly easier than 4140.

Cutting the bearing holes in the hinge piece.

Taping holes in the hinge piece. Kept the holes blind for looks.

Adding the pin holes to the top plate. Holes were drilled and reamed to 0.250" and then drilled 0.850" for the 5/16 threads. Using the remaining piece of 0.250 hole to maintain alignment of the hinge pins.

Adding pivot screw holes to the upper plate. The G0755 is just big enough to thread with the part on edge!

Making the hinge pins. Using a vertical shear tool to cut down the 5/16 threaded rod to match the 1/4 inch holes.

Rounding the corners of the upper plate for clearance for the hinge.

Drilling and counter-sinking the lower plate for the hinge piece.

Corner rounding the hinge piece with 0.25 radius tool. Learned from Tom's Techniques that the corner rounding mill cutters like climb milling better than conventional. First time using these cutters but they worked well.

IMG_4136.jpg

Taping the piviot holes for the lower plate.

IMG_4139.jpg
IMG_4140.jpg

Preparing the material for the support slides for the sides of the plate. Wouldn't you know that the only handy material was twice as wide and half again as thick as needed for the part?
Might have been quicker to go out and buy more but too late now.

That's as far as I have progressed to date. I will post more photos as the work gets done.

Got back at it yesterday and this morning.

Facing the material down to 3/16 before sawing to the width.

Hinge pins trimmed to length and slotted for screwdriver.

Just needs a few holes now.

IMG_4155.jpg

I thought I got tired of drilling - tapping was worse!

IMG_4159.jpg

Top plate complete.

IMG_4160.jpg

Bottom plate complete. Holes match the t-slots of the mill for the times that I cannot use it in the vise.

Complete!

Really nice. I need to do one of these.
I think you may want a tapping head for the mill though.

Nice project Jim, BTW is that a home made table for using the band saw in vertical mode. I'm thinking of making one myself Do you have any photos of the making?

Thanks Jim,

That would be great, I'm particularly interested in how the plate attaches to the saw frame, and how to keep it square.

Thanks,

Bob.

G'day Jim,

I just noticed that you are in Moncton. My partner and I stayed there back in 2015 while on an 8 month motorcycle tour of USA and Canada, stayed 3 days while we had our bikes serviced and new tyres fitted.

Hope it was in the summer and hope you got a chance to interact with some of the Maritime folks. I grew up in Western Canada but likes the east coast so much during a work stint there that we moved back to Moncton to retire.

Very nice work Cobra. I particularly like the hinging details.

- I would love to try that McMaster supplied ground steel. May I ask, how are you able to order from them? I thought they stopped to shipping to Canada/international common mortals with the exception of institutions or large industrial clients? It was a sad day when I learned that, I use to use them for all sorts of goodies.

- I've thought many times about buying or building an angle fixture. I've always wondered how the typical side brackets/bolts would hold position under typical milling/drilling loads. What makes me think this is my own amateur experience with slight movement shift of parts even held in rigid mill vise jaws without supporting parallels. My machinist buddy says these angle plates are more common on grinders where down loads are smaller, but there are apparently other versions that have some kind of adjustable under arm support. I saw one old school picture that could be this, but forgot to save the link or take a pictures. Any thoughts on this aspect?

I have heard the comment on McMaster as well but had no problem opening an account - probably 3 years ago. Their service continues to be great.
The other option may be the Metal Supermarkets. I am pretty sure that they have an outlet in Calgary. I have purchased ground stock from them in Toronto when I lived there. It was O1 but they may have mild steel as well.

For the times I have used the angle plate, I have not had an issue with it moving but I was taking light cuts. I was using end mills and would not have been going over a 0.02" depth of cut.

So far, so good.

Hi Bob.
I have attached some photos of the table. I also did up a small sketch of the table. Dimensions for this table are for the Busy Bee 4X6 that is available in Canada though most of them are similar.
The smaller plate replaces the little plate/table that came with the saw for work in the horizontal direction. It is held on with two counter sunk 10-24 screws, replacing the 5mm screws that came with the saw. The position of them obviously comes from your particular saw.
The same can be said about the slots for the blade.
The shape of the lower/inside plate allow clearance on the left corner for the vice jaw and on the right for material when cutting at 45 degrees.
The hinges are just 0.125" drill rod 0.75" long. Alignment of these and the 4-40 screws is important to have the table move and be square.
One improvement that could be done is to relieve the back edge of the table plate as shown in the sketch. This will allow the table to swing past 90 degrees when in the up position, making it more stable and not as likely to come down making a hell of a racket and scaring the crap out of the hobbyist!
Any questions, give me a shout.
If you need the sketch as a drawing file, shoot me a PM with your email.

Jim

Thanks Jim, very nice work as with all your projects.

My saw although not much smaller than yours It's 125 x 125mm or 5"x 5". Is, from the look of your pics it is a somewhat lighter build and was not ever intended to be used in the vertical mode, it comes from Taiwan and is quite well made but a little on the light side.

I have modified it so far that I can lift it up so that the blade is now vertical. It was made to only lift to about 75 deg above vertical.

I like your design, but will have to make something slightly different as the little plate that guides the blade into the rear roller guides is onl;y a little bit of bent sheet metal held on with only one 4mm scraw.

I was think of taking off the aluminium block that carries the rear roller guides and fixing a plate behind this block where it bolts to the main frame with I think two 6mm socket head cap screws, and build up the table bracket from there. I was also going to use a long, say, 100mm x 6mm cap screw as the hinge, and remove the table plate when not in use.

It has also occurs to me that some extra rigidity could be obtained by having a leg drop down from the underside of the table and be clamped in the vice, which would not be in use during the vertical blade operation.

It will be a slow build as I don't get much shop time, and have three other projects that I'm starting.

1. A set of 4 machine skates, so that I can move the lathe away from the wall when I need to get behind it. and a means of lifting it up onto the skates.

2. A vertical spindle milling attachment for my lathe as I simply don't have room for a milling machine. And one does need a mill of some sort.

3. a small jib crane that attaches to the back corner of the headstock for lifting heavy things onto the lathe, such as 4 jaw chuck and the milling attachment, when it's finished. I expect it will weigh about 50 Kg. / 110lb.

then I should be ready to take on anything.

Cheers,

Bob.

Yes Jim it was summer although we did have some rain while in Moncton. We really only stopped there because of the HD dealership, our bikes needed servicing and I needed some new rear tyres on my bike (trike) and also on my little trailer. And I had been told there was a big tyre place not far past the HD dealers.

Bob.
