UPDATE: FENCE, RAIL & CLAMP IN PROGRESS

Here’s today’s progress on the Biesmeyer style fence for my dinky toy saw. The spring clamps are clamping the cam handle together prior to working it into shape. The socket head cap screws on the top will secure the fence to the clamp. I was going to use plain hex cap screws but I thought the socket heads would look better and either way they are going to be counter-bored below the surface.
I already tried the clamp with the MDF cam and it clamps completely solidly tight. I’ll probably go to a Maple or oak cam later on. You can see in some of the photos how the ¾”dowel is in there acting as a plunger for the cam to press. I’m likely going to need to bush the holes with at least steel bushings or they will wear oval and I want the pieces that wear out to be replaceable not the ones that aren’t.
I’m going to build a micro-adjuster next for it because I don’t believe as nicely as it slides around that it will be an ‘adjust by bumping’ type of fence. This fence is very heavy.
p.s. If you ever use carriage bolts then you need to use the thing that is lying on top of the fence by the cap screws to prevent the square on the carriage bolt from rounding out the hole.

Further update:
I tried the fence out with the clamping assembly attached in one place by the cap screw and clamps in two other locations and all I can say is: ‘That dog will hunt!’ It is heavy but it glides over the table and it locks right in square again. And, the longer fence face even gives a better cut without the wobble at the beginning and end of the cut. It is so smooth sawing against it with the Melamine faces but I am still intending on installing thread inserts and using a removable face so as not to wreck the body of the fence itself. At this point I would be willing to say; ‘It worked’. I have my Biesmeyer fence now.

Looking better every day, keep going, good progress.

This looks extremely clever to me and it looks practical to boot.Your MDF wheel might not last very long. That stuff delaminates awfully easy, but no harm in giving it a try. That said, it might be ideal because it probably gives a little when it contacts the plunger. I wonder if a hardish rubber wheel wouldn’t be ideal? Great work with a lot of ingenuity!

I have had a delamination problem with MDF which I use as a collar on my ball chuck. I like to use the MDF because it doesn’t leave marks on the ball. My solution was to glue an oak ring on the front to reinforce it.

Reinforcing on both sides in your case might be possible using hardwood rings on both sides with connecting bolts, to keep the MDF compressed so it can’t spread much at the contact point with the plunger. Here’s a pic of my solution just to illustrate.

dang this is sweet. It really goes to show, it’s not the tools that make things possible, but the individual that is using them. Fantastic job.

Thank you all for your supportive and generous comments. So, here it is basically finished; is anything ever, which it never really is. Stefang, you can see how the handle and cam are integrated together but it is compressing the cam a little but not too much. I will probably make the eccentric/cam out of some maple that the fellow with the cabinet shop gave me or some of the jungle wood he also gave me that is a sub-species of mahogany; really dark and oily like lignum vitae or similar. [Can you believe that Word’s dictionary knew ‘lignum Vitae’ and made no effort to correct it?]
You can see that it already has its own push block in an effort to keep my fingers attached to my hand. I close my eyes when sawing; I don’t want to see my fingers get chopped off. Just jesting. [I told the conductor one day on our light rail [MAX] that I close my eyes when I cross the tracks not heeding the computer telling you to look both ways when crossing the tracks and he was shocked. I told him, ‘I don’t want to see myself getting hit by a train, light or not.’]
I’m going to make a micro-adjuster this afternoon for it after I eat to recharge my batteries.
I’m considering facing some of the areas with Formica™ and if I don’t summarily I will use this means to repair wear in the future if I live that long with my liver condition which it appears I will because I thought that I was going to be a different configuration of chemicals by now considering what my physicians told me and my own research.
Please share with me any ideas you all may have and thank you once again for being so kind in your commentaries.

However you do it I think this is an amazing fence system and far better than the one that came with my combo machine. I’m sure you will get a lot of pleasure out of it. Sorry about your liver problem. Doctors are very often wrong so I figure everyone has at least a 50/50 chance to beat their diagnosis, and I hope you do too.
