These are the inner sections that fit into the Hogarth frames I'm currently making.

The profile is cut from the pine stretcher STR1 from R&H and all praise to R&H as there is not a single knot in the whole batch sent.

I've had to cut such a wide rebate because they are going around a set of Hogarth prints with a lot of uneven and wide margins. Instead of using a mount which would look wrong in an 18th century frame, I evened up the borders by using the sanded slip section to cover up a lot of the paper.

Going that deep into a pine section can get quite scary. You can only take out 2mm at a time, otherwise the pine will splinter and even shatter the moulding. So that was passing all 16m of moulding 8 or 9 times through the spindle moulder.

Now I have to lock myself away for 2 or 3 days pressing out compo.

With such a wide and thin overhang there might be some warping. I was told this by a picture frame moulding milling vendor (Vermont Hardwoods) who warned against it. He suggested gluing 2 pieces of timber together to relieve the stress issue causing warping.

Good point, and I suppose that could happen on a long production length.

These lengths are just over 1 meter, so there's no danger of warping. Also, if you look closely, the actual lip of the moulding is less than 2mm thick with an additional small detail along the centre.
Try working that out of a flat piece of pine.

Impressive and a good way to hide paper rather than a mount.

If i am taking a biggish rebate out, i take most out with the table saw and leave the last 2-3mm to do on the spindle moulder. It is quicker, and quite often you will end up with a useful bit of timber (spacers etc). Also less chance of splintering timber.

I quite often like to cut rebates using a table saw and just clean up afterwards with a bit of sandpaper, it usually turns out quite well. I've also got three different 1/4 inch routers and a boxed set of various router bits, but the table saw is a lot easier for me. Producing my own skinny frame mouldings with a deep rebate is something that I am particularly excited about, again because of the potential for warping. Generally speaking deep skinny hogarths are not really my thing and unfortunately the quality of most commercially produced hogarth moulding is also not particularly great either. Even where some suppliers offer narrower and wider hogarth mouldings in their range, the moulding are not really adequate for producing larger frames and I have needed to use a sub frame to stiffen the frame, if the frames size is more than just a very small frame. At best it's not really my idea of fun. There's never enough rebate depth to accomodate any kind of sub frame and the quality of the wood used by the moulding manufacturer, does not usually provide much density for securing the sub frame with screws. It such cases, I usually cut a very basic sub frame moulding on the table saw and secure the the sub frame with multi points and some screws.

The rebate depths available with the the commercially available hogarth mouldings, which I normally use are not really adequate for accomodating double mounts, as the backing board is tending to hang out of the back of the frame and fixing the backing board in place to easily becomes problematic. As far as I know, this is probably much the same with other hogarth moulding from most other suppliers as well. I suspect the many customers are expecting to save money by choosing these basic hogarth mouldings and are quite taken a back when I need to add a sub frame to ensure the necessary strength and durability and therefore need to charge them more. Personally, I don't much care when customers, object to the extra cost and take their work elsewhere. There not a lot of satifaction in trying to make a silk purse, out of a sows ear. When I am ordering hogarth mouldings, I don't much like the one where the gold is too bright and glitsey. So I usually order the Simons 0585 version, which is not only a little bit wider, but also has a much nicer dull gold effect as well. I'm really impressed with anyone who is able to create their own hogarth moulding from scratch, as I don't think that is going to be an easy thing to do!
