Pretty straightforward to fabricate something effective from the pictures at https://www.lathes.co.uk/myford/page10.html on Tonys site.

Many ways of doing the deed depending on facilities, skill, available materials and just plain taste.

I prefer a lift off style aligned by sliding clip hooks and held down by gravity so it can be easily removed if need be but there is a risk of vibration rattles. These days a few strategically placed magnets would probably sort any such issues. The ones I’ve made in the past have either been heavy and / or had a couple of easy to get at from the front. screws holding the top to the wall so rattles have not been a worry. I don’t advise bolting to the back due to potential access issues. A fixed splash-back does make moving harder.

I like the “speed frame” knock together square tube system with simple flat panels pop riveted in place as a basis for this sort of thing. Simple rectangular frame at the back made to sit on top of the chip tray end panelling. A single piece sticking forward to support the bit at the tailstock end. If you want to support the angled top at the tailstock end a bit of creative bracketed will be needed to get the angle as speed frame joints are 90° only. Panels on the lathe side of the frame. Creatively shaped clip bars hanging over the back to locate.

Objectively speed frame is on the pricy side but it does make a neat job easy for those of us whose panel beating and welding skills are not as good as we would like to believe.
