Coping sled for the Spindle Moulder

I completed this small coping sled a couple of weeks ago, despite it not being fully complete I thought I would post it anyway, as I know not when the additional required parts will arrive from the Pacific rim.

Other than the awaited parts (two small T slot router cutters) I had all the parts and scraps in the workshop. The sled is intended for my 3HP spindle moulder/shaper but as it it stacked away ready for our hopefully imminent house move I presently cannot access the table to gauge how far the t-track slot Is from the cutter aperture. Rather than guesstimate it I will fit a track bar to the base once I actually need the SM again.

Some of the parts and hardware used. -

Made from 12 & 18mm Baltic birch ply scraps and some hardware from my bits and bobs hardware drawer. I did measure the overall size of the sled at the time, but the two weeks passing since I finished it, the details of which have escaped me. I think it is around 12” long x 9 3/4” wide and allows a board of up to 5 1/2” wide, less whatever size backer block I use to prevent blow out when I pass it through the cutter.

The top sled slides over the base between two M8 bolts I tapped and expoxied into the base. I cut two stopped slots at the router table. A straightforward operation, I just increased the cutter height around 1/8” on each pass. Simple

I drilled two 1/4” holes on the back fence to accommodate T- bolts, counter boring the holes to permit the knobs to sink below the surface of the rear of the fence. I only did this because the T bolts I had were not long enough. A mis -calculation on my part. However, with the holes countersunk the knobs not only travel far enough through the fence for the bolts to engage a slot I will rout in all backer blocks, to reduce blow out on the work. it has the added benefit of gripping more securely with less effort.

I also applied several strips of adhesive backed rough cast tape, the kind used on stair treads to reduce foot slip. This should aid the top sled and backer block from slippage when all clamped down.

A nut for a handle was expoxied into the top of the rear fence using shafting expoxy I use to fit golf club shafts into the club heads. It’s messy stuff so some painter tape over the hole prevented a lot of clean up ensuring a neat tidy job.This particular type of expoxy takes a couple of days to cure fully but I figured the properties of the adhesive would better suit this project. Passing timber through a high speed steel cutter always gives me the willies. Keeping my hand as far away as possible relieves some of the anguish this process brings me.

I had originally intended to use a similar handle on the front of the sled, as I had at the rear, however a trial run proved it didn’t sit well with me, so I made up a block from laminated 12mm ply scraps and moulded a contour around the edges to fit my hand. I then glued and screwed it to the top sled. As well as being good and secure the ergonomics suit me better.

Two coats of a water based poly were applied for protection on all wooden parts. A couple of lock down lever clamps complete the build at this stage.

Thanks for reading this far.

I like the design. Looks to be really safe. I to need to make something like this to us on my big router table. Hope the house and impending move are smooth for you.

Thanks for the comments gents.
Not sure how much woodworking I will get done prior to the house move, Vernon. However I’m bound to be kept well employed in the new house.
Cheers

I love my shaper. This would be a good addition to my selection of fixtures.

Hope the house move has been going well for you. Can’t wait to see update to this, and definitely motivated to do one for myself now that I see roughly how I could go about doing it.
