Default Homemade Pin Router

I have been wanting a pin router for some time but was not satisfied with what was out there. Meaning I could not afford it or it's purpose for what I wanted it to do was limited.

So I created this one,
The features are;
*Mechanical control of lowering router with foot control.
*I can raise the carriage in the back up to 12" off the table and still have the same foot control.
*I have a slide table for rabbits dado's or cutting tenons.
*The head can angle left or right up to 45 degree's for cross cutting at angles or routing into an angled cut.
* It has a 1/4" pin in it that is adjustable for height and has 1/2" and 3/4" bushings for larger bits.
*It has a stop feature for depth and one to hold it for depth.
*It has a moving measurement rule to set and adjust depths.
*The down movement of the router is run on modified drawer guides encased to help prevent sawdust from entering the bearings.
*The foot control is tied to a floating choke cable. This gives the unit the ability to work mechanically and still have adjustments for height. The foot control gives 5" of vertical movement.

I am really pleased with it and am discovering different ways to use it. I am making a jig to be able to cut and rout circles too.

I will let you know how things go with it.

Holy smokes, that is fantastic! You did a great job, I like all the features, especially the adjustable angle, too cool.

Have you thought of building some kind of safety guard for it?

Mark,
A fine job, it looks like you'll have an endless supply of new ways to enjoy it.
Sometimes the ingenuity of the members on this forum just amazes me.

Hi Mark:

You have achieved something rather difficult with the router -- the ability to use it at an angle. Nicely done. With your permission, I'll include it in the pin router section of my notes. I'd love to see some of the things you make with the angled router. Please also note that when you now combine bits cutting at an angle you open up a tremendous range of new mouldings and shapes -- add to that your circle cutting jig and now you have some very interesting options, only duplicated by a pivot frame.

MArk, it looks fantastic! Well done.

Actually the bits I liked best are the twist-handles for the locking bolts! A really nice touch.

I am interested that you should use drawer slides for your apparatus, do they give sufficient support? I am thinking that they would be slightly loose and would chatter? I have used the carriages from very old electronic printers which have aluminium (?) castings running on ground steel rods and are particularly good if you find (literally in some cases) the right ones.

I am about to embark on a router lathe with an oscillating facility, posts will follow as it progresses. I like making pretty things, but most of my clients just want a nicer wardrobe.

As it seems with every one else, do let us see what you can do with it :-) Gemma xx

Way to go, Mark! I, too, would be concerned about the rigidity of the slides you've chosen especially if heavy cuts were made, but nevertheless it is an excellent and ingenious solution you'e arrived at. My own experience of using industrial cast-iron pin routers is that they generally have a much deeper swan neck and so can handle larger pieces, but I concede that it is difficult to see how that could be achieved in timber

From my own commercial experience I'd say that industrial overhead routers are one of the most difficult machines to guard adequately, fortunately they are normally used in conjunction with a workholding jig and template rather than freehand and it is the design of the jig which allows for same use. Almost all the conventional guards I've used or seen either limit visibility of impede easy working

Thanks everyone!
To answer a couple questions;
Yes safety is always a concern but like Phil P explained it is hard to put safety devices on this. I do wear a face mask and anything I run through it is either attached to a jig or a sacrifice piece of wood to keep my hands away from danger.

Using Drawer slides was a last resort until I figured out a way to keep them tight. Everything else I tried was to sloppy or so tight it wouldn't move very well.

I included some pictures, I am not sure if you can understand what I did but here goes.
I started with 16" full extension guides. There are 3 tracks on the full extension which created to much play so I removed the smallest inner one and its bearings.
These 2 tracks are fairly tight but to tighten them a little more and keep them tight I tightly fitted a piece of hardwood into the inner track and fastened them with screws through the back.
Then when I mount them in the carriage on the machine the outer tracks are pinned between 2 pieces of wood so they can't flex at all. This tightened everything up and there is no play at all.
I am not sure if this makes sense but it works.

Super job! I have a Shop Smith Pin Router which I prefer to simply call it an "Overhead Router." I do little if any actual Pin Routing on my unit, I prefer it to simply replace my Table Router for most jobs. I often wonder why these Pint Routers are not more popular.
In any event, you did a super job on this project.
